Tips for Reading User's Guides On-Screen

When reading a ZyXEL User's Guide On-Screen, keep the following in mind:

• If you don't already have the latest version of Adobe Reader, you can download it from http://www.adobe.com.
• Use the PDF's bookmarks to quickly navigate to the areas that interest you. Adobe Reader's bookmarks pane opens by default in all ZyXEL User's Guide PDFs.
• If you know the page number or know vaguely which page-range you want to view, you can enter a number in the toolbar in Reader, then press [ENTER] to jump directly to that page.
• Type [CTRL]+[F] to open the Adobe Reader search utility and enter a word or phrase. This can help you quickly pinpoint the information you require. You can also enter text directly into the toolbar in Reader.
• To quickly move around within a page, press the [SPACE] bar. This turns your cursor into a "hand" with which you can grab the page and move it around freely on your screen.
• Embedded hyperlinks are actually cross-references to related text. Click them to jump to the corresponding section of the User's Guide PDF.

Above is the NSA in a home network. Users back up and share data on the NSA. The DMA-2500 plays the NSA's media files on the TV. A USB hard drive provides extra storage space and files are copied directly from the USB mass storage device to the NSA.

Place the NSA behind a firewall and/or IDP (Intrusion Detection and Prevention) device to protect it from attacks from the Internet.

Note: See Chapter 18 on page 359 for a more detailed list of NSA features.

Refer to the Quick Start Guide for hardware connections and how to install and remove hard drives from the disk trays.

Note: Turn off and disconnect the NSA before you install or remove the internal hard disk.

1.2 Hard Disks

Your NSA has two internal hard disk bays. Install one or two SATA (Serial Advanced Technology Attachment) hard disks. Note that both SATA hard disks are treated as internal or SATA volumes in the Storage > Volume screen (Section 7.4 on page 153). Any hard disk connected to the USB port(s) is considered an external or USB volume.

1.3 LEDs

    F --> G["Password"]
    G --> H["Release to Clear All Settings"]

- Press the RESET button until you hear one beep (after about two seconds), then release it. You will hear one more beep after you release the button. This resets the NSA's IP address and password to the default values.

- Press the RESET button until you hear two beeps. After the second beep, continue pressing the button for five more seconds, then release it. You will hear three quick beeps after you release the button.

This resets the NSA to the factory default configuration. All settings you have configured on the NSA, including IP address, password, user accounts, groups, and so on will be reset to the factory defaults.

The reset process does NOT affect the volume settings, nor data stored on the NSA.

You should periodically back up your configuration file to your computer (see Section 15.5 on page 318 for details about managing the NSA's configuration file). You could then restore your configuration in the event that you or someone else reset the NSA to the factory defaults.

Note: You should keep the NSA in a secure location in order to prevent unauthorized reset of the device.

NAS Starter Utility

2.1 Overview

This chapter describes the NAS Starter Utility. Use the NAS Starter Utility to find, set up, and manage the NSA as well as copy files to it and access the files on it.

Make sure you have a backup of any existing data in the hard disk before installing it in the NSA. Using the initialization wizard formats the hard disk and deletes all data in the process.

There is a NAS Starter Utility available for Windows XP, Windows Vista, or Windows 7. Click Help to open a web help page about the NAS Starter Utility screens. NAS Starter Utility screens are shown here as they display with the Windows platform.

Note: Refer to the Quick Start Guide for your NSA's hardware connections and the steps for installing the NAS Starter Utility.

2.2 Starting the NAS Starter Utility

• The NAS Starter Utility broadcasts a request packet when you first run it. Each NSA has an NAS Starter Utility Agent that always listens and responds to requests from the NAS Starter Utility. The NAS Starter Utility receives the response packet that contains information, such as host name, IP, and so on.
• If you plan to use more than one NSA in your network, configure them with unique server names. This enables you to identify each NSA in the NAS Starter Utility screens.

2.3 NAS Discovery Screen

Use this screen to view the NSAs in your network. The NSA's Server Name (default is 'nsa221'). See Section 2.9 on page 44 for how to change it to a more recognizable one in your network.

Start the NAS Starter Utility (click the icon in your Desktop or in Start >

Programs > ZyXEL > NAS Starter Utility). The first time you open the NAS

Starter Utility the discovery screen appears as follows.

3.4.3 File Browser

Click File Browser to open the following screen. Use the file browsing screens to play, open, upload, and download files. A share is a set of user access permissions for a specific folder on a volume (gives someone access to a folder). It is equivalent to the Windows concept of a shared folder, but the access rights are independent of the folder (you configure the share and the folder separately). You

can map a share to a network drive for easy and familiar file transfer for Windows users.

• A folder icon with a hand indicates a share.
• The administrator owns and manages the public shares.
• Double-click a media file to open it. Double-click other types of files to be able to save them.
• Click to the right of a file or folder name to select it.
• Use the [SHIFT] key to select a range of entries. Hold down the [CTRL] key to select multiple individual entries.
• Drag and drop files to open a screen that lets you choose whether to copy or move them.
• You can upload files of up to 2 GB in size.
• You can download individual files of up to 4 GB in size with Mozilla Firefox and Internet Explorer 7 and later or up to 2 GB in size with Internet Explorer 6.

3.4.4 Share and Folder Names

The name can only contain the following characters:

- Alphanumeric (A-z, 0-9) and Unicode.

The NSA allows FTP access to shares, folders or files with names encoded in the UTF-8 (8-bit UCS/Unicode Transformation Format) format. So your FTP client must support UTF-8 in order to access shares, folders or files on the NSA with Unicode names.

• Spaces
• _ [underscores]
  • . [periods]
• [dashes]

Other limitations include:

• All leading and trailing spaces are removed automatically.
• Multiple spaces within names are converted to a single space.
• Share names must be unique (they cannot be the same as other share names).
• The NSA creates automatic volume names for external (USB) disk volumes. These are a type of share, so the share name you configure cannot conflict with the external (USB) disk volume names. "ExtVol1" or "ExtVol2" are examples of external (USB) disk volume names.
• Folder names must be unique (they cannot be the same as other folder names).

• The minimum character length of a name is one character, that is a name cannot be blank.

• The maximum character length of share name is 239 characters.

• Unicode is supported for share names, although your FTP client must support UTF-8. Full support should be available in all Windows versions after Windows 2000.

4.2 Creating a Volume

This section shows you how to create a volume on your NSA.

Creating a volume deletes all existing data in the hard disk. Make sure you have a backup of your existing data before following the steps in this section.

Your NSA has two bays for SATA (Serial Advanced Technology Attachment) hard disks. The JBOD storage method is used if you are using a single hard disk for your NSA.

This JBOD volume shows up in the Storage > Volume screen (Section 7.4 on page 153) as follows.

Storage - Volume Internal Volume Status Volume Disk Configuration Disk(s) Capacity Actions Healthy Volume1 RBCD RBCD disk1 0.11% (523.01 MB) Used 465.14 GB Total 99.89% Free Create an Internal Volume External Volume Status Volume File System Disk(s) Capacity Actions There are currently no volumes. Create an External Volume

4.2.1 Creating a RAID 1 Volume

This storage method allows recovery of data if your hard disk fails. To create a RAID 1 volume, you must install two SATA hard disks in your NSA. There are two ways to create a RAID 1 volume:

• Click the Migrate button - If you already have a SATA hard disk with a volume and you later install a second SATA hard disk in your NSA, use the Migrate button to convert the existing JBOD volume to a RAID 1 volume.
• Click the Create a SATA volume button - Use this if there are no existing volumes in your NSA.

4.2.2 Migrate Button

Do the following steps to create a RAID 1 volume.

1 Once you install a second SATA hard disk in the NSA, the Storage > Volume screen shows the Migrate button.

Storage - Volume Internal Volume Status Volume Disk Configuration Disk(s) Capacity Actions Healthy V RBCD MBCD Disk Capacity (JBOD) disk2 74.00 GB Total 1.98% (1.47 GB) Used 98.02% Free Create an Internal Volume

2 Click the Migrate button and you can see the following progress bar. Wait for the RAID 1 volume to be created. This may take quite a while depending on how much data you have in the original volume.

4.2.3 Create an Internal Volume Button

If you do not have an existing volume in the Storage > Volume screen, do the following steps to create a RAID 1 volume.

1 In the Storage > Volume screen, click Create an Internal Volume.

Storage - Volume Internal Volume Status Volume Disk Configuration Disk(s) Capacity Actions There are currently no volumes. Create an Internal Volume External Volume Status Volume File System Disk(s) Capacity Actions There are currently no volumes. Create an External Volume

2 In the Disk Configuration screen, you can select the storage method.

• Type in the Volume Name for your RAID 1 volume. The volume name can be 1 to 31 characters (a-z, 0-9, " " [spaces], "_", and ".").
• Choose RAID 1 and click Apply.

This deletes all existing data in the SATA hard disk. Make sure you have a backup of any existing data in the hard disk.

Disk Configuration Volume Name RAID 1_Example performance but does not deliver fault tolerance. If one drive falls then all data in the array is lost. RAID1 RBCD RBCD RBCD Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks. Apply Cancel

The NSA starts creating the volume and you can see the following progress bar. Wait for the RAID 1 volume to be created.

3 The Storage > Volume screen displays with your RAID 1 volume.

Internal Volume Status Volume Disk Configuration Disk(s) Capacity Actions Resync 0.1% RAID 1_Example ABCD disk1 0.11% (523.03 MB) Used Data Protection (RAID1) disk2 465.14 GB Total 99.89% Free Create an Internal Volume External Volume Status Volume File System Disk(s) Capacity Actions There are currently no volumes.

4.3 Deleting a Volume

Delete an existing volume in your NSA by doing the following steps.

1 In the Storage > Volume screen, select the volume you want to delete and click the delete icon.

Storage - Volume Internal Volume Status Volume Disk Configuration Disk(s) Capacity Actions Healthy Volume1 ABCD disk1 0.11% (523.01 MB) Used 465.14 GB Total 99.89% Free Create an Internal Volume External Volume Status Volume File System Disk(s) Capacity Actions There are currently no volumes. Create an External Volume

2 A confirmation window appears as follows. Click Yes.

Delete Volume 'Volume 1' ALL Data On this Volume will be DELETED. Are you sure you want to DELETE this Volume? Yes No

This deletes all existing data in the volume. Make sure you have a backup of any existing data in the hard disk.

4.4 File Sharing Tutorials

The following sections cover using the NSA for file sharing. This chapter assumes you have already followed the Quick Start Guide instructions to perform initial setup and configuration (so you have a working volume). See the rest of this User's Guide for details on configuring the NSA's various screens.

4.4.1 Creating a User Account

Bob wants to create accounts for his sons Jimmy and Kevin. This is how he would do it.

1 Log into the NSA web configurator (see Section 3.3 on page 48) and click System > Administration to go to the configuration screens.

Settings Administration System

2 Click Sharing > Users to open the Users screen. Then click Add User.

Users Add User Search Edit User Delete User Info Display Number 20 Go to Page 1 Page 1 Of 1 User Type Username Bob admin Page 1 Of 1

3 Configure the screen as follows and write down the username and password to give to Jimmy. If the username and password are the same as Jimmy's Windows login, Jimmy will not need to enter a username and password when he logs into his share from his computer. Set the Account Type to User so Jimmy doesn't get to configure the whole NSA. Click Apply to create the account.

Add User Username Jimmy New Password **** Password (Confirm) **** Account Type Administrator User Available Group(s) children family Group Membership Add Selected Group(s) → Group Membership ← Remove Selected Group(s) Apply Cancel

4 The account now displays in the Users screen.

Page 1 Of 1 User Type Username Bob Jimmy admin Page 1 Of 1

Now that Bob has created Jimmy's account, he can go through the steps again to create another account for Kevin. After both accounts are created, he can go to Section 4.4.2 on page 76 to create shares for Jimmy and Kevin.

4.4.2 Creating a Share

Suppose Bob has already created separate accounts for his sons Jimmy and Kevin. Now Bob wants to create a share for each son. He also wants to make sure that each son can only access his own share (to keep them from deleting each other's files). This is how he would do it.

1 In the NSA's administration web configurator screens, click Shares > Add Share. Click Add Share to create a new share.

Shares Add Share Recycle Bin Edit Share Delete Share Browser Status Share Type Share Name Share Path Share Owner Permission Type pre-defined video volume/video admin public pre-defined photo volume/photo admin public pre-defined music volume/music admin public built-in public volume/public admin public built-in admin volume/admin admin private

2 Specify a name for the share and select which volume it should be on. Configure the screen as follows. Then click Edit.

Add Share Share Name Jimmy Volume volume ( 183.26 GB ) Make this share owned by admin Enable This Share Enable Recycle Bin Publish this share to Media Server Publish this share to Web Share Access Advanced Edit Apply Cancel

3 Configure the screen as follows to give Jimmy full access right to the share. Then click Apply to create the share.

Share Access Configuration Available User(s)/Group(s) Bob Kevin anonymous-ftp everyone children family Authority : Full Jimmy admin Note: You may select multiple users/groups by using Ctrl + Click. Apply Cancel

Now that Bob has created Jimmy's share, he can go through the steps again to create another share for Kevin.

4.4.3 Creating a Group

After creating user accounts for Jimmy and Kevin, Bob wants to create a group for his sons and another one for the parents. Bob can assign access rights to his sons' group for certain shares such as a cartoons share and allow only the parents' group to access the scary movie share. This is how he would create the group.

1 In the NSA's administration web configurator screen, click Groups > Add Group.

Groups Add Group Search Edit Group Delete Selected Group(s) Display Number 20 Go to Page 1 Page 1 Of 1 Status Group Name Page 1 Of 1

2 Specify a name for the group. Select the user(s) you want to add to the group from the Available User(s) list and click Add Selected User(s). Configure the screen as follows. Then click Apply to create the group.

Add a New Local Group Group Name Children Available User(s) Group Membership Bob admin Simmy Kimv Group Membership Add Selected User(s) → Remove Selected User(s) Apply Cancel

Now that Bob has created a group for Jimmy and Kevin, he can go through the steps again to create another group for the parents. Then he can see the rest of the tutorials for how to use the groups in assigning access rights to shares.

4.4.4 Accessing a Share From Windows Explorer

If you map a NSA share (where data is stored) to a Windows network drive, you can use Windows Explorer to transfer files to and from the NSA as if it was another folder on your computer. Here he maps Jimmy's share to Jimmy's computer.

1 Start Windows Explorer and go to the NSA's server name ("nsa221" is the default) or IP address.
2 Click Tools > Map Network Drive.

NSA File Edit View Favorites Tools Help Address \nsa Folders Map Network Drive... Disconnect Network Drive... Synchronize... Folder Options...

3 Select the network drive that you want to map the NSA to from the Drive list box. This example uses I. Then browse to and select the share on the NSA. Click Finish.

Map Network Drive Windows can help you connect to a shared network folder and assign a drive letter to the connection so that you can access the folder using My Computer. Specify the drive letter for the connection and the folder that you want to connect to: Drive: I: Folder: Browse... Example: \\server\share ✓ Reconnect at logon Connect using a different user name. Sign up for online storage or connect to a network server. < Back Finish Cancel

Browse For Folder Select a shared network folder Nsa Nsa Nsa admin Jimmy music photo public video Printers and Faxes Make New Folder OK Cancel

4 Enter the username and password for Jimmy's account and click OK. You do not need to do this if the username and password are the same as Jimmy's Windows login.

Connect to nsa localdomain Connecting to nsa User name: Password: Remember my password OK Cancel

5 After the mapping is done, you can then simply copy and paste or drag and drop files from/to your local computer's drives to or from this network folder. Just like the NSA's share was another folder on your computer.

Now that Bob has mapped Jimmy's share to Jimmy's computer, he can go through the steps again to map Kevin's share to Kevin's computer.

4.4.5 Accessing a Share Using FTP

You can also use FTP to access the NSA. Suppose Jimmy is temporarily using a different computer and wants to access his share without mapping it to the computer. This is how he would do it.

1 Open the FTP client (Windows Explorer is used here) and type "ftp://username@server" where "username" is the account's username and "server" is the NSA's IP address or server name.

4.5 Download Service Tutorial

This tutorial covers using the NSA to download a file from the Internet. Use this same procedure for BitTorrent downloads as well as regular HTTP (web) and FTP downloads. See Section 9.11.2 on page 207 for more on the download service.

4.5.1 Copying/Pasting a Download Link

1 Open your Internet browser (this example uses Internet Explorer).
2 Find a download link for the file you want. In this example, www.zyxel.com has a Download Now link for downloading a datasheet for ZyXEL's GS-2024 (a device for making phone calls over the Internet).

Download Library USER'S GUIDE Model: GS-2024 Version: 3.80 Language: English OS: N/A Release Date: 06-20-2008 Size: 7 MB Description: error correction Download Now

Note: Make sure the link opens either the file you want or a pop-up window about how to handle the file.

Note: It is also OK for the link to open a .torrent file. If you are redirected to a screen that says the download should start in a few seconds, there may be a link to click if the download does not start automatically. See if that link opens the file or the pop-up window.

3 Right-click the download link and select Copy Shortcut in Internet Explorer (or Copy Link Location in Firefox).

6 The download task appears in the Download Service screen's Active or Queue tab. It may appear in the Completed tab if the NSA already finished downloading the file or it may appear in the Error tab if the NSA failed to download the file.

By default the NSA stores all downloads in the admin share's download folder. See Section 4.4.4 on page 78, Section 4.4.5 on page 80, or Section 4.4.6 on page 82 for how to access a share.

4.5.4 Configuring the Download Service Preferences

Once you added a list of download tasks to the NSA (see Section 4.5.1 on page 83 and Section 4.5.3 on page 91), you can have the NSA download files during a specific time period of the day. You can also configure the BitTorrent settings to control bandwidth and optimize download efficiency.

Say you have the NSA turned on all the time, but you only want the NSA download files at night. Here is how you use the download period control feature to set the time range.

1 Click Applications > Download Service > Preferences to open the General Settings screen.
2 Select Enable Download Period Control and use the arrows to adjust the time period from 23:30 to 09:00. Click Apply to save your changes. The NSA only downloads files within this 9.5-hour period every day.

Preferences General Settings BitTorrent Location of Downloaded Files Share Path Put incomplete downloads in admin /download Move completed downloads to admin /download Edit Note: 1. BT Jobs will be stored in /admin/download/incoming 2. HTTP/FTP Jobs will be stored in /admin/download 3. Jobs triggered by RSS Channel will create the Channel Name to /admin/download Download Period Control Enable Download Period Control Download Service is active in the specified time period (hh:mm - hh:mm) 23 30 09 00 Apply Reset Cancel

Note: If you configure the Power On/Off Schedule feature in the Power Management screen, make sure your active download period does not conflict with the power-off period.

Note: If power failure occurs during the active download period, the NSA will verify whether the downloaded files were damaged. If a file is corrupted, the NSA will download the file again. If the file is intact but not completely downloaded, the NSA will resume the download task after it restarts.

3 When it is not the download time, you see a message in the Download Service screen, indicating the active download period.

Download Service Download service allows you to download files from the Internet directly to the NSA.

Amy has to activate the NSA's auto upload feature. See Section 11.4 on page 274 for more details on setting up a Flickr account for auto upload. In this example Amy select the NSA's photo share for auto upload.

This is how Amy would transfer the files from her USB disk to the NSA.

1 Click Applications > Copy/Sync Button in the navigation panel to open the screen.
2 Configure the copy settings as shown and click Apply.

4.9 FTP Uploadr Tutorial

FTP Uploadr can automatically upload files saved on the NSA to a remote FTP server. Amy wants to share files on her NSA with Susan. They each have an NSA

at home, so Susan has to set her NSA as an FTP server for Amy to automatically send files using FTP Uploadr.

    B --> C["Susan's NSA"]

To set the NSA as an FTP server, click Applications > FTP to open the FTP screen. Select Enable FTP and click Apply.

FTP Enable FTP Connection Limit 10 Connection Limit: 20 Idle Timeout 15 minutes Max timeout: 300 minutes Port Number 21 Enable Anonymous FTP Access Customize the port range for data transfer. Note: To configure a share to allow anonymous FTP access go to the configure shares page and modify a share's access rights to allow the user 'Anonymous FTP'. Character Set [UTF-8] Apply Reset

Susan also has to create a user account and share on her NSA for Amy to upload files. The share is used for files uploaded from Amy's NSA. Amy will then use the following information to configure FTP Uploadr on her NSA.

Table 17 FTP Uploadr Tutorial: FTP Server Information

FTP Domain Name or IP Address	example2.com
FTP User Name	Amy
FTP Password	xxxxx

Now, anyone who connects to the NSA's Web Configurator screens will automatically do so by HTTPS. Use a secure method to let your users know the correct fingerprint for the NSA's certificate so they can check it before adding a security exception (as in steps 6 to 7 on pages 119 to 120). See the next section for how to use FTPES with the NSA for secure FTP transfers.

4.11 Using FTPES to Connect to the NSA

This section covers how to use FTP over Explicit TLS/SSL with the NSA for secure FTP transfers. Before you go through this section, read Section 4.10 on page 110 to configure HTTPS. This example uses FileZilla.

1 Open FileZilla and click File > Site Manager > New Site.

• Configure the Host field with the NSA's address.
• Set the Servertype to FTPES - FTP over explicit TLS/SSL.
• Configure the account name and password.
• Click Connect.

Always trust certificate in future sessions. OK Cancel

The shares and folders to which Gonzo has access display. Now you can use FTP to securely transfer files to or from the NSA. Use a secure method to let your users know the correct fingerprint for the NSA's certificate so they can check it before adding a security exception.

4.12 How to Use the BackupPlanner

Note: The screens and links in this section appear only after you have installed and enabled BackupPlanner. BackupPlanner is an application that you can install using Package Management (see Chapter 10 on page 219.)

Use the NSA's BackupPlanner to have a backup of your files and folders.

Schedule backups for times when the network is not busy (like at night or on weekends). For example, you might do daily backups of important individual files or folders and a weekly general archive. You can save backups to another location so your files can survive even if the original RAID or NSA fails.

4.12.1 Creating an Archive Backup

To backup the NSA every week to a remote NSA:

1 Click Protect > Backup > Add Job.

2 Identify the backup job and select Archive.

New files are often added to the shares that you need to back up and existing files are not frequently changed so select Incremental. The NSA does a full backup first and later only copies source files that are new and/or modified since the last backup. This example sets the NSA to do another full backup after every four incremental backups.

4 For this example, assume the connection to the German branch office is a good one and not many files need to be backed up so leave the compression off.

• Turn on the encryption to protect these sensitive files during the transfer. The final files stored on the remote NSA will be unencrypted (usable).
• Restrict the bandwidth usage to 256 KB/s to stop the archives from using all of your network connection's available bandwidth.
• You don't have to configure a purge policy for a synchronization backup.
• Click Next.

System Setting

6.1 Overview

This chapter gives an overview of the various features included in the system setting screens. You can identify your NSA on the network and set the time that the NSA follows for its scheduled tasks/logs.

6.2 What You Can Do

• Use the Server Name screen (Section 6.4 on page 142) to specify the NSA's server and workgroup names.
• Use the Date/Time screen (Section 6.5 on page 143) to set up date/time and choose a time zone for the NSA.

6.3 What You Need to Know

Windows/CIFS

Common Internet File System (CIFS) is a standard protocol supported by most operating systems in order to share files across the network.

• CIFS is included by default in Windows operating systems.
• You can use Samba with Linux to use CIFS.
  • CIFS transfers use security.

Time Lag

Time lag occurs when the time on the NSA falls behind the time on the time server. This may happen if:

• the time server is no longer reachable
• if the NSA is shut down often (the NSA internal battery keeps time when the NSA is shut down and this may cause possible variance)

• power surges occur.

The NSA gives no warning if time lag occurs. You should resynchronize the time after a power surge or after you have shut down the NSA several times.

6.4 The Server Name Screen

Click System Setting > Server Name to open the following screen. Use this screen to configure your CIFS settings. In this screen you can set your server name and specify if your NSA is a part of a workgroup.

Note: CIFS cannot be disabled on the NSA.

Storage

7.1 Overview

Several NSA features require a valid internal volume. This chapter covers the management of volumes and disks (both internal and external).

Use the Storage screen (Section 7.2 on page 148) to display information on all volumes, create internal and external volumes, and configure the volume's properties.

7.1.1 What You Need to Know About Storage

Volume

A volume is a storage area on a disk or disks. You can create volumes on the internal disks and external disks attached to the USB port(s). You can spread a volume across internal disks but not between internal and external disks.

Storage Methods

RAID (Redundant Array of Independent Disks) or JBOD (Just a Bunch of Data) is the storage method that the NSA uses. The storage method you use depends on how many disks you have and how many volumes you want to create. It's important that you consider this carefully as all data is deleted when you re-create a volume. See Figure 7.6.2 on page 157 for details on choosing a storage method.

Finding Out More

See Section 7.6 on page 156 for more technical background information on storage.

7.2 The Storage Screen

The Storage screen allows you to create and edit volumes in the NSA.

7.2.1 Disk Replacement Restrictions

See the Quick Start Guide for information on replacing disks in the NSA. When replacing a disk in a degraded or down RAID volume, the new disk must be at least the same size or bigger than the other disks that are already in the RAID volume, so as all data in the volume can be restored.

For example, if you have RAID with 250 GB disks, you must put in a 250 GB or bigger disk as a replacement in order to restore all original data in that volume. If the replacement disk is of a higher capacity, the extra space on the disk will not be used except if it is for a RAID 1 volume and you follow the Expanding a RAID 1 Volume procedure.

Note: The NSA automatically repairs a degraded RAID volume if you insert an empty disk without an existing file system. Otherwise, when you replace a disk you must go to the Storage > Internal Volume > RAID screen, select the degraded array, and click Repair.

Resynchronizing or Recovering a RAID 1 Volume

Resynchronizing or recovering a RAID 1 volume that was down is done block-by-block, so the time it takes depends more on the size of your hard drive(s) than the amount of data you have on them.

Note: Do not restart the NSA while the NSA is resynchronizing or recovering a volume as this will cause the synchronization to begin again after the NSA fully reboots.

Note: You can access data on a RAID volume while it is resynchronizing or recovering, but it is not recommended.

Expanding a RAID 1 Volume

Replace a RAID 1 volume's hard disks with higher capacity hard disks to be able to increase the RAID 1 volume's capacity. For example, you have two 500 GB hard disks. You replace one 500 GB hard disk with a 1 TB hard disk and repair the volume. After the NSA finishes resynchronizing the volume, you replace the second 500 GB hard disk with another 1 TB hard disk and repair the volume again. After the NSA finishes the second repair, use the Expand icon to have the RAID1 volume use the rest of the hard disk capacity.

7.2.2 Storage Screen

Click Storage > Volume in the navigation panel to display the following screen. Use this screen to display internal and external volumes on the NSA.

Note: It is recommended to scan the volume every three months or 32 reboots.

Apply	Click this to save your changes and create the volume.
Cancel	Click this to exit this screen without saving your changes or creating a volume.

Note: Once you create the first volume on the NSA, it is recommended to restart the NSA for better performance.

7.3.1 Volume Status

You (the administrator) can see the status of a volume in the Status or Storage screens.

The NSA has the following classifications for the status of a volume:

• Healthy if all disks in the volume are OK and the file system is functioning properly.
• OK means the USB connected device is functioning properly.

• Resync when you create a RAID volume.

• Recovering appears when repairing a RAID 1 volume. (A RAID1 volume was once degraded, but you have installed a new disk and the NSA is restoring the RAID1 volume to a healthy state.)

• Degraded when a volume is currently down, but can be fixed. Data access may be slower from a degraded volume, so it's recommended that you replace the faulty disk and repair the volume as soon as you can.
• Inactive when a disk is missing from a RAID 0 volume or a two-disk JBOD volume. The volume is unusable. If you removed one of the disks you should be able to re-install it and use the volume again (as long as you did not change anything on the disk). If a disk has failed, you need to replace it and re-create the whole volume. All data will be lost. See page 340 for how to install or replace a hard drive.
• Down when a volume is down and can not be fixed.

A down RAID volume cannot be used until you repair or replace the faulty disk(s) in the volume. Degraded means one of the disks in the RAID volume is not available but the volume can still be used. For a degraded volume, you should replace the faulty disk as soon as possible to obtain previous performance. See your Quick Start Guide for more information on replacing a disk.

If it's down, then the only indication is that you can no longer transfer files to/from the shares in the down volume. If it's degraded, then file transfer to/from the shares in the degraded volume will be slower.

Note: There is no explicit message from CIFS that tells users their volume is degraded or down.

7.4 Editing a Volume

7.6 Storage Technical Reference

This section provides some background information about the topics covered in this chapter.

7.6.1 Volumes and RAID

A volume is a storage area on a disk or disks. You can create volumes on the internal disks and external disks attached to the USB port(s). You can spread a volume across internal disks but not between internal and external disks.

RAID (Redundant Array of Independent Disks) or JBOD is the storage method that the NSA uses. The storage method you use depends on how many disks you have and how many volumes you want to create. It's important that you consider this carefully as all data is deleted when you re-create a volume.

Note: Back up your data before deleting or re-creating a volume!

For example if you originally have one disk configured as JBOD, and you then install another disk and want to configure the two disks to use RAID 1, you should first back up all your data on the two disks (see the Memeo Autobackup utility on the included CD) and then restore your data later after you create the new volume type.

Below is a table that summarizes some attributes of the various RAID levels as supported on the NSA. For capacity and storage efficiency, "S" is the size of the smallest drive in the array, and "N" is the number of drives in the array.

Storage efficiency assumes all drives are of identical size.

Performance rankings are approximations.

Write Performance	YYYY	YYY

7.6.2 Choosing a Storage Method for a Volume

The following is a guide to help you choose a storage method for the various number of disks supported on the NSA. See Section 7.6.3 on page 157 for theoretical background on JBOD and the RAID levels used on the NSA. Typical applications for each method are also shown there.

One Disk

If you only have one disk, you must use JBOD. All disk space is used for your data - none is used for backup. If the disk fails, then you lose all the data on that volume (disk). You can add another disk to your one-disk JBOD volume later without having to re-create shares, access rights, and so on. Alternatively, you could create a different JBOD volume if you install a second disk. (and create new shares, access rights and so on).

Two Disks:

You may choose JBOD, RAID 0 or RAID 1. With two disks you could create:

• up to two JBOD volumes
  • one RAID 0 or RAID 1 volume

- Choose JBOD for flexibility and maximum usage of disk space for data.

- Choose RAID 0 if performance matters more than data security. RAID 0 has the fastest read and write performance but if one disk fails you lose all your data on the volume. It has fast performance as it can read and write to two disks simultaneously. Performance may matter more than data security to gamers for example. This method may also be acceptable for data that is already backed up somewhere else.

- Choose RAID 1 if data security is more important than performance. Since RAID 1 mirrors data onto a second disk, you can recover all data even if one disk fails, but the performance is slower than RAID 0.

7.6.3 Storage Methods

This section contains theoretical background on JBOD and the RAID levels used on the NSA. Redundant Array of Independent Disks (RAID) is a method of storing data on multiple disks to provide a combination of greater capacity, reliability, and/or speed. JBOD (Just a Bunch Of Disks) is not a RAID storage method but it is included in this discussion.

These are some terms that you need to know in order to understand storage systems.

- Mirroring

In a RAID system using mirroring, all data in the system is written simultaneously to two hard disks instead of one. This provides 100% data redundancy as if one disk fails the other has the duplicated data. Mirroring setups always require an even number of drives.

- Duplexing

Like in mirroring, all data is duplicated onto two distinct physical hard drives but in addition it also duplicates the hardware that controls the two hard drives (one of the drives would be connected to one adapter and the other to a second adapter).

- Striping

Striping is the breaking up of data and storing different data pieces on each of the drives in an array. This allows faster reading and writing as it can be done simultaneously across disks. Striping can be done at the byte level, or in blocks. Byte-level striping means that the first byte of the file is sent to the first drive, then the second to the second drive, and so on. Block-level striping means that each file is split into blocks of a certain size and those are distributed to the various drives. The size of the blocks used is also called the stripe size (or block size).

- Parity

In mirroring 50% of the drives in the array are reserved for duplicate data. Parity is another way to allow data recovery in the event of disk failure using calculations rather than duplicating the data. If you have 'n' pieces of data, parity computes an extra piece of data. The 'n+1' pieces of data are stored on 'n+1'drives. If you lose any one of the 'n+1' pieces of data, you can recreate it from the 'n' that remain, regardless of which piece is lost. Parity protection is used with striping, and the "n" pieces of data are typically the blocks or bytes distributed across the drives in the array. The parity information can either be stored on a separate, dedicated drive, or be mixed with the data across all the drives in the array.

Note: In the following figures, A1, A2, A3 and so on are blocks of data from the A file. Similarly, B1, B2, B3 and C1, C2, C3 ar blocks of data from the B and C files.

JBOD

JBOD allows you to combine multiple physical disk drives into a single virtual one, so they appear as a single large disk. JBOD can be used to turn multiple different-sized drives into one big drive. For example, JBOD could convert 80 GB and 100 GB drives into one large logical drive of 180 GB. If you have two JBOD volumes (with one disk in each), a failure of one disk (volume) should not affect the other volume (disk). JBOD read performance is not as good as RAID as only one disk can be read at a time and they must be read sequentially. The following figure

shows disks in a single JBOD volume. Data is not written across disks but written sequentially to each disk until it's full.

Table 26 JBOD

A1	B1
A2	B2
A3	B3
A4	B4
DISK 1	DISK 2

RAID 0

RAID 0 spreads data evenly across two or more disks (data striping) with no mirroring nor parity for data redundancy, so if one disk fails the entire volume will be lost. The major benefit of RAID 0 is performance. The following figure shows two disks in a single RAID 0 volume. Data can be written and read across disks simultaneously for faster performance.

Table 27 RAID 0

A1	A2
A3	A4
A5	A6
A7	A8
DISK 1	DISK 2

RAID 0 capacity is the size of the smallest disk multiplied by the number of disks you have configured at RAID 0 on the NSA. For example, if you have two disks of sizes 100 GB and 200 GB respectively in a RAID 0 volume, then the maximum capacity is 200 GB (2 * 100 GB, the smallest disk size) and the remaining space (100 GB) is unused.

Typical applications for RAID 0 are non-critical data (or data that changes infrequently and is backed up regularly) requiring high write speed such as audio, video, graphics, games and so on.

RAID 1

RAID 1 creates an exact copy (or mirror) of a set of data on another disk. This is useful when data backup is more important than data capacity. The following

figure shows two disks in a single RAID 1 volume with mirrored data. Data is duplicated across two disks, so if one disk fails, there is still a copy of the data.

Table 28 RAID 1

A1	A1
A2	A2
A3	A3
A4	A4
DISK 1	DISK 2

As RAID 1 uses mirroring and duplexing, a RAID 1 volume needs an even number of disks (two or four for the NSA).

RAID 1 capacity is limited to the size of the smallest disk in the RAID array. For example, if you have two disks of sizes 150 GB and 200 GB respectively in one RAID 1 volume, then the maximum capacity is 150 GB and the remaining space (50 GB) is unused.

Typical applications for RAID 1 are those requiring high fault tolerance without need of large amounts of storage capacity or top performance, for example, accounting and financial data, small database systems, and enterprise servers.

RAID and Data Protection

If a hard disk fails and you're using a RAID 1 volume, then your data will still be available (but at degraded speeds until you replace the hard disk that failed and resynchronize the volume). However, RAID cannot protect against file corruption, virus attacks, files incorrectly deleted or modified, or the NSA malfunctioning. Here are some suggestions for helping to protect your data.

• Place the NSA behind a hardware-based firewall. It should have stateful packet inspection, IDP (Intrusion Detection and Prevention), and anti-virus (like ZyXEL's ZyWALL UTM products for example).
• Use anti-virus software on your computer to scan files from others before saving the files on the NSA.
• Keep another copy of important files (preferably in another location).

Network

8.1 Overview

This chapter discusses the network configuration screens. The Network screens allow you to configure TCP/IP and PPPoE settings for the NSA.

8.2 What You Can Do

• Use the TCP/IP screen (Section 8.4 on page 163) to assign the NSA a dynamic or static IP address and DNS information.
• Use UPnP port mapping (Section 8.5 on page 166) to automatically configure your Internet gateway's firewall and Network Address Translation (NAT) to allow access to the NSA from the Internet.
• Use the PPPoE screen (Section 8.6 on page 170) to configure PPPoE settings for a direct Internet connection.

8.3 What You Need to Know

IP Address

The NSA needs an IP address to communicate with other devices on your network. The NSA can get an IP address automatically if you have a device on your network that gives them out. Or you can assign the NSA a static (fixed) IP address.

DNS Server Address

A DNS (Domain Name System) server maps domain names (like www.zyxel.com) to their corresponding numerical IP addresses. This lets you use domain names to access web sites without having to know their IP addresses. The NSA can receive the IP address of a DNS server automatically (along with the NSA's own IP address). You can also manually enter a DNS server IP address in the NSA.

Jumbo Frames

Jumbo frames are Ethernet frames larger than 1500 bytes. They enable data transfer with less overhead. The bigger the frame, the better the network performance. Your network equipment such as computers, switches and routers must be capable of supporting jumbo frames. You also need to enable jumbo frames in all related network devices.

PPPoE

Point-to-Point Protocol over Ethernet (PPPoE) allows the NSA to establish a direct Internet connection if you do not have a router. PPPoE is a dial-up connection. You need a username and password from your Internet Service Provider (ISP) to set up the connection.

Jumbo Frames

To use jumbo frames, your LAN must support 1 Gbps transmissions (Gigabit Ethernet). All of your network devices (computer Ethernet cards and switches, hubs, or routers) must also support the same size of jumbo frames that you specify in the NSA.

Note: If you enable jumbo frames on the NSA in a network that does not support them, you will lose access to the NSA. If this occurs, you will have to restore the factory default configuration. Push the RESET button on the NSA's rear panel and release it after you hear a beep.

In the following example, the NSA has jumbo frames enabled and set to 8KB frames. This means the computer, notebook computer, and switch must also have jumbo frames enabled and be capable of supporting 8KB frames.

8.4 The TCP/IP Screen

Use the TCP/IP screen to have the NSA use a dynamic or static IP address, subnet mask, default gateway and DNS servers.

Click Network > TCP/IP in the navigation panel to open the following screen.

Note: If you change the NSA's IP address, you need to log in again after you apply changes.

8.5 UPnP Port Mapping Screen

Use UPnP (Universal Plug and Play) port mapping to allow access from the WAN to services you select on the NSA. It is recommended that you place the NSA behind an Internet gateway firewall device to protect the NSA from attacks from the Internet (see RAID and Data Protection on page 160 for firewall type suggestions). Many such Internet gateways use UPnP to simplify peer-to-peer network connectivity between devices. UPnP can automatically configure the Internet gateway's firewall and Network Address Translation (NAT) to allow access to the NSA from the Internet.

Figure 79 UPnP for FTP Access

192.168.1.20

graph LR
    A["Database"] <-->|TCP: 21| B["River"]
    B <-->|TCP: 21| C["Internet"]
    C --> D["Computer"]

In the above example, UPnP creates a firewall rule and NAT port forwarding mapping to send FTP traffic (using TCP port number 21) from the public IP address a.b.c.d to the NSA's private IP address of 192.168.1.20.

Use the NSA's UPnP Port Mapping screen to configure the UPnP settings your Internet gateway uses to allow access from the WAN (Internet) to services you select on the NSA. You can also set which port Internet users need to use in order to access a specific service on the NSA.

Note: To use UPnP port mapping, your Internet gateway must have UPnP enabled.

If your Internet gateway supports Port Address Translation (PAT is sometimes included with a port forwarding feature), you can have the Internet users use a different TCP port number from the one the NSA uses for the service.

Figure 80 UPnP Port Address Translation for FTP Example

192.168.1.20

graph LR
    A["Storage Server"] <-->|TCP: 21| B["River"]
    B <-->|TCP: 2100| C["Internet"]
    C --> D["Computer"]

In the above example, the Internet gateway uses PAT to accept Internet user FTP sessions on port 2100, translate them to port 21, and forward them to the NSA.

8.5.1 UPnP and the NSA's IP Address

It is recommended that the NSA use a static IP address (or a static DHCP IP address) if you will allow access to the NSA from the Internet. The UPnP-created NAT mappings keep the IP address the NSA had when you applied your settings in the UPnP Port Mapping screen. They do not automatically update if the NSA's IP address changes.

Note: WAN access stops working if the NSA's IP address changes.

For example, if the NSA's IP address was 192.168.1.33 when you applied the UPnP Port Mapping screen's settings and the NSA later gets a new IP address of 192.168.1.34 through DHCP, WAN access stops working because the Internet gateway still tries to forward traffic to IP address 192.168.1.33. Since you can no longer access the NSA from the WAN, you would have to access the NSA from the LAN and re-apply your UPnP Port Mapping screen settings to update the Internet gateway's UPnP port mappings.

8.5.2 UPnP and Security

UPnP's automated nature makes it easier to use than manually configuring firewall and NAT rules, but it is also less secure. Using UPnP may make your network more susceptible to snooping and hacking attacks.

8.5.3 The NSA's Services and UPnP

This section introduces the NSA's services which an Internet gateway can use UPnP to allow access to from the Internet.

BitTorrent

BitTorrent is a distributed peer-to-peer file-sharing protocol that the NSA's download service can use. Using UPnP port mapping for BitTorrent lets BitTorrent work faster.

CIFS (Windows File Sharing)

Common Internet File System (CIFS) is a standard protocol supported by most operating systems in order to share files across the network. Using UPnP port mapping for CIFS allows users to connect from the Internet and use programs like Windows Explorer to access the NSA's shares to copy files from the NSA, delete files on the NSA, or upload files to the NSA from the Internet.

If you configure UPnP port mapping to allow CIFS access from the WAN but cannot get it to work, you may also have to configure the Internet gateway to also allow NetBIOS traffic. See Section 6.3 on page 141 for more on CIFS.

FTP

File Transfer Protocol is a standard file transfer service used on the Internet. Using UPnP port mapping for FTP allows remote users to use FTP from the Internet to access the NSA's shares. A user with read and write access to a share can copy files from the share, delete files from the share, or upload files to the share. See Section 9.4 on page 176 for more on FTP. If you use UPnP to allow FTP access from the WAN, you may want to use a different WAN port number (instead of the default of port 21) to make it more secure. Remember to tell the remote users to use the custom port number when using FTP to access the NSA.

HTTP (Web Configurator)

You can use UPnP port mapping to allow access to the NSA's management screens. If you use UPnP to allow web configurator access from the WAN, you may want to use a different WAN port number (instead of the default of port 80) to make it more secure. Remember to use the custom port number when accessing the NSA's web configurator from the Internet.

HTTP (Web Published Shares)

This is the NSA's web publishing feature that lets people access files using a web browser without having to log into the Home screens. Use UPnP port mapping to allow access to these files from the Internet without having to enter a user name or password. See Section 9.7 on page 192 for more on web publishing.

8.5.4 Configuring UPnP Port Mapping

Click Network > UPnP > Port Mapping to display the UPnP Port Mapping screen.

Use this screen to set how the Internet gateway's UPnP feature configure's the Internet gateway's NAT IP address mapping and port mapping settings. These settings allow Internet users connected to the Internet gateway's WAN interface to

access services on the NSA. You can set which port Internet users need to use to access a specific service on the NSA.

Note: Some Internet gateways will delete all UPnP mappings after reboot. So if the Internet gateway reboots, you may need to use this screen again to re-apply the UPnP port mapping.

Figure 82 Network > UPnP > Port Mapping

Network - UPnP Port Mapping UPnP Port Map Settings Note: • In order to use a port number on the gateway device(WAN) that is different from that on the NSA (LAN), your gateway device should support Port Address Translation. • For Distributed Hash Table (DHT) support, the BitTorrent service will also attempt to open the following UDP port: 9089 LAN Service Name LAN Port BitTorrent ▶ 9090 CIFS (Windows File Sharing) 445 FTP 21 HTTP (Web Configurator) 80, HTTP (Web published shares) 80 172.16.26.2 WAN Service Name Enable WAN Access WAN Port BitTorrent ▶ ✓ 9090 CIFS (Windows File Sharing) □ -- FTP □ -- HTTP (Web Configurator) □ -- HTTP (Web published shares) □ -- : This service requires that the LAN port setting is the same as the WAN port setting ○ : This port setting currently conflicts with another service's port. ◆ : This port is being used by another service but will be replaced if you apply this setting.

9.3 What You Need to Know

FTP

File Transfer Protocol (FTP) is a file transfer service that operates on the Internet. A system running the FTP server accepts commands from a system running an FTP client. FTP is not a secure protocol. Your file transfers could be subject to snooping.

FTPES (File Transfer Protocol over Explicit TLS/SSL)

File Transfer Protocol over Explicit TLS/SSL (FTPES) is a file transfer service that uses either TLS (Transport Layer Security) or SSL (Secure Sockets Layer) for secure transfers across the Internet. It requests for a mutual method of encryption from the FTP server for its file transfer sessions. Your FTP client must be set to use FTPES as in the following example.

Figure 84 FTP Client Example

Media Server

The media server feature lets anyone on your network play video, music, and photos from the NSA (without having to copy them to another computer). The NSA can function as a DLNA-compliant media server and/or an iTunes server. The NSA streams files to DLNA-compliant media clients or computers using iTunes. The Digital Living Network Alliance (DLNA) is a group of personal computer and electronics companies that works to make products compatible in a home network.

iTunes Server

The NSA iTunes server feature lets you use Apple's iTunes software on a computer to play music and video files stored on the NSA. You can download iTunes from www.apple.com.

Download Service

The NSA's download service downloads files from the Internet directly to the NSA. You do not have to download to your computer and then copy to the NSA. This can free up your computer's system resources.

The NSA can download using these protocols.

• HTTP: The standard protocol for web pages.
• FTP: A standard Internet file transfer service.
• BitTorrent: A popular distributed peer-to-peer files sharing protocol.

BitTorrent

The NSA includes a BitTorrent client for fast downloading and sharing of large files (such as educational public domain videos). With BitTorrent, you share while you're downloading the file. BitTorrent breaks up the file and distributes it in hundreds of chunks. You start sharing the file as soon as you have downloaded a single chunk.

Web Publishing

Web publishing lets you “publish” shares (containing folders and files) on the NSA so people can access the files using a web browser without having to log into the Home screens. This way you can share files with others without them having to know and enter a username and password.

For example, if you want to share photos in a FamilyPhotos share, you could "web publish" it and others could use a web browser to access the photos at http://my-NSA's-IP-Address/MyWeb/FamilyPhotos.

Broadcatching

Broadcasting is the downloading of digital content from Internet feeds. Use broadcatching to have the NSA download frequently updated digital content like TV programs, radio shows, podcasts (audio files), and blogs.

RSS

RSS (Really Simple Syndication) is a format for delivering frequently updated digital content. A channel uses a feed to deliver its contents (items). Subscribe the NSA to a feed to be able to download the contents.

9.4 FTP Server

9.11 Technical Reference

This section provides technical background information on the topics discussed in this chapter.

9.11.1 Sharing Media Files on Your Network

The media server feature lets anyone on your network play video, music, and photos from the NSA (without having to copy them to another computer). The NSA can function as a DLNA-compliant media server and/or an iTunes server. The NSA streams files to DLNA-compliant media clients or computers using iTunes. The Digital Living Network Alliance (DLNA) is a group of personal computer and

electronics companies that works to make products compatible in a home network.

• Publish shares to let others play the contained media files.
• The media server is a convenient way to share files you download using the broadcatching service (see Section 9.8 on page 194).
• Hardware-based media clients like the DMA-2500 can also play the files. See Section 18.4 on page 366 for the supported multimedia file formats.

Note: Anyone on your network can play the media files in the published shares. No user name and password or other form of security is used. The media server is enabled by default with the video, photo, and music shares published.

Songs from the iTunes Store

After using iTunes on your computer to download songs from Apple's iTunes Store, you can copy them to the NSA. Many of these songs have DRM (Digital Rights Management). At the time of writing, you can use your Apple account ID and password to authorize up to a total of five computers to play the files. To authorize a computer, open iTunes and click Store > Authorize Computer.

9.11.2 Download Service

The NSA's download service downloads files from the Internet directly to the NSA. You do not have to download to your computer and then copy to the NSA. This can free up your computer's system resources. The download service also handles your broadcasting downloads. See Section 9.8 on page 194 for information on broadcasting.

The NSA can download using these protocols.

• HTTP: The standard protocol for web pages.
• FTP: A standard Internet file transfer service.
• BitTorrent: A popular distributed peer-to-peer files sharing protocol.

Note: Do not use the NSA for illegal purposes. Illegal downloading or sharing of files can result in severe civil and criminal penalties. You are subject to the restrictions of copyright laws and any other applicable laws and will bear the consequences of any infringements thereof. ZyXEL bears NO responsibility or liability for your use of the download service feature.

Torrent Files

The NSA needs a “.torrent” file for BitTorrent to download a file. The torrent file gives the NSA information about the file to be downloaded (and shared) and the tracker(s) (computers) that coordinates the distribution of the file.

When you add a BitTorrent download task in the NSA's web configurator screens, you can copy and paste the URL of the torrent file. The NSA automatically downloads the torrent file and saves it in a torrent folder within the folder where the NSA stores downloaded files (the admin share's download folder by default).

If you already have the torrent file saved on your computer, you can just specify its location when adding a download task through the web configurator. Another method is to use FTP or a CIFS program (Windows Explorer for example) to copy the torrent file into the torrent folder. The NSA automatically uses the torrent file.

After your BitTorrent download and sharing are finished, you can go to the incoming folder within the destination share or folder and delete the .torrent file if you need to free up hard disk space.

9.11.3 Link Capture Browser Plugin

The link capture browser plugin is an add-on feature for your web browser. Use the plugin to directly add a file's URL to the NSA's download service.

Note: The link capture browser plugin is located in the included CD.

The following screen displays how the plugin works.

Send Link... Copy Link Direction Send to NSA Properties Pictures Podcasts Short Form Video Sounds - Samples

Instead of copying and pasting a file's URL to the NSA's download service, you can right-click on the URL in the web browser and select Send to NSA. The URL is then added to the NSA's download service list.

See Section 4.5.2 on page 86 and Section 4.5.3 on page 91 for tutorials about installing and using the link capture browser plugin.

Note: At the time of writing the plugin supports Internet Explorer 6.0/7.0 and Mozilla Firefox 2.0/3.0; it does not support Windows 7.

9.11.4 Download Service Notification

Use the download service notification to keep track of downloaded files on the NSA. You can subscribe to the NSA's download list on your computer. When the NSA finishes downloading new files, your RSS reader displays the information and links for the files. You can also download the files from the RSS reader to your computer.

See Section 4.5.5 on page 95 for a tutorial about using the download service notification.

In the Download Service screen, select Enable Download Notify and click Apply. An RSS feed icon appears. Click the icon to subscribe to the NSA's download list.

Note: The download service notification only keeps track of files downloaded via BitTorrent.

9.11.5 BitTorrent Security

When you download using BitTorrent, you reveal your IP address. This increases the risk of hacking attacks, which can be protected against by a good firewall.

Use a Hardware-based Firewall

Place a hardware-based firewall between your network and the Internet (a software-based firewall on your computer would just protect the computer itself, not the NSA since your computer is not between your NSA and the Internet).

Figure 104 Firewall

graph LR
    A["Router"] --> B["Rugger"]
    C["Router"] --> B
    D["Router"] --> B

    style F fill:#ccf,stroke:#333
    style G fill:#cff,stroke:#333
    style H fill:#ffc,stroke:#333
    style I fill:#ffc,stroke:#333

Ideally your firewall should have the following:

• Stateful packet inspection to control access between the Internet and your network and protect your NSA (and computers) from hacking attacks.
• IDP (Intrusion Detection and Prevention) to detect malicious packets within normal network traffic and take immediate action against them.
• Anti-virus to check files you download for computer viruses.

BitTorrent and Your Firewall

The anti-virus feature on a firewall probably cannot check BitTorrent downloads for viruses, so use anti-virus software on your computer to scan the NSA for viruses.

When you download using BitTorrent, many other BitTorrent users are also trying to download the file from you. The firewall slows this down because by default, it only allows traffic from the Internet in response to a request that originated on the LAN (it lets you get files from the Internet and blocks those on the Internet from getting files from you).

Figure 105 Firewall Blocking Incoming BitTorrent Requests

    E["Container"] -->|Incoming BitTorrent requests blocked| B
    B -->|Outgoing BitTorrent request allowed| F["Internet"]
    B -->|Corresponding BitTorrent reply allowed| G["Internet"]

To speed up BitTorrent file transfers, configure your firewall's port forwarding to send incoming TCP port 9090 and UDP port 9089 connections to the NSA. You probably need to use your firewall's HTML (web-based) configuration interface to

set this up (see the firewall's manual for details). You may also have to configure a corresponding firewall rule.

9.11.6 Web Publishing Example

This example covers how to configure the Web Publishing screen to let people use a web browser to access a share named FamilyPhotos without logging into the Home screens and shows how to access the share through the Internet.

1 Click Applications > Web Publishing and configure the screen as shown (enable the web publishing and move FamilyPhotos over to Published Shares) and click Apply.

Figure 107 Applications > Web Publishing (Example)

Applications - Web Publishing Web Publishing Disable Web Publishing Enable Web Publishing Support HTTPS Port Number 80 Note: The format of URL: "http://IP_Address:Port_Number/Share_Name/", "https://IP_Address/Share_Name/" Unpublished Shares Jimmy Jimmy2 admin music photo public video Published Shares FamilyPhotos ← Unpublish Selected Share(s) Publish Selected Share(s) → Apply Reset

2 Now open your web browser and type in the address of the NSA's FamilyPhotos web page. In this example, the NSA's IP address is 192.168.1.33, and the name of the web-published share is FamilyPhotos. So you would enter "http://192.168.1.33/MyWeb/FamilyPhotos/" in your browser's address bar. Then press [ENTER] or click Go. A screen displays listing the share's files.

• Click a file's link to open the file.
• Right-click a file's link and select Save Target As.. (in Internet Explorer) to save a copy of the file.
• Click a label in the heading row to sort the files by that criteria.
• To customize how the page looks and works, create an index.html or index.htm file and store it in the share.

9.11.7 Web Publishing

Web publishing lets you “publish” shares (containing folders and files) on the NSA so people can access the files using a web browser without having to log into the Home screens. This way you can share files with others without them having to know and enter a user name and password.

For example, if you want to share photos in a FamilyPhotos share, you could "web publish" it and others could use a web browser to access the photos at http://my-NSA's-IP-Address/MyWeb/FamilyPhotos.

Note: The NSA does not use any security for the files in the published folders. It is not recommended to publish shares if you do not have the NSA behind a good hardware-based firewall. See page 209 for more on firewalls.

Additionally, you can use HTML editing software (not included) to create an index.html or index.htm file to define and customize how your website works and looks.

Accessing Web-published Shares from the Internet

You need to use a public address to access the NSA's web-published shares from the Internet. If your NSA uses a private IP address, you may need to use the public IP address of your Internet gateway and configure NAT or port forwarding on your Internet gateway and possibly firewall rules in order to let people access the NSA's web-published shares from the Internet.

Web Publishing Port Number

If the web-published shares use a port number other than 80 (the normal port for web traffic), users must include it after the NSA's IP address in order to access the NSA's web-published shares. For example, say you specified port 8080, the NSA's IP address is 192.168.1.23, and the name of the web-published share is FamilyPhotos. You would have to enter "http://192.168.1.23:8080/MyWeb/FamilyPhotos/" in your browser's address bar to access the share's web page.

The NSA's web configurator uses port 80. To make the web configurator more secure, you can have the web-published shares use another port number. Then you can configure one set of firewall rules and NAT or port forwarding settings on

your Internet gateway specifically for allowing access to the web-published shares and another separate set of rules for accessing the NSA's web configurator.

9.11.8 Channel Guides for Broadcasting

Here are some popular broadcatching channel guide web sites.

Note: ZyXEL does not endorse these web sites and is not responsible for any of their contents. Use these or any other web sites at your own risk and discretion.

9.11.9 Printer Sharing

The NSA can act as a print server. A print server lets multiple computers share a printer. Connect a printer to the NSA's USB port to let multiple computers on your network use it. See www.zyxel.com for a list of compatible printers.

Figure 110 Printer Sharing

You can copy files from a USB device to the NSA or from the NSA to a USB device. Simply press and release the COPY/SYNC button to start copying files. See Section 9.10 on page 204 for details about configuring the copy settings.

The following figure illustrates how copying files works when you copy files from a USB device to the NSA. The same concept applies when you copy files from the NSA to a USB device.

Figure 111 Copying Files Example
Before Copy

Both storage devices contain file A.

• A copy of files A and B from the USB device is transferred to the NSA.
• File A from the USB device replaces file A on the NSA.

9.11.11 Synchronizing Files

Synchronization makes the contents on the target device identical to the ones on the source device. You can synchronize files from a USB device to the NSA or from the NSA to a USB device. In addition, you may also synchronize files in both directions simultaneously.

Press and hold the COPY/SYNC button until you hear a beep to synchronize files. See Section 9.10 on page 204 for details about configuring the synchronization settings.

USB -> NSA or USB <- NSA

When you synchronize files in one direction, contents on the source device replace the files on the target device.

The following figure illustrates how synchronization works when you synchronize files from a USB device to the NSA. The same concept applies when you synchronize files from the NSA to a USB device.

Figure 112 Synchronizing Files Example 1

USB A B NSA A B

Both storage devices contain A.

• A copy of files A and B from the USB device is transferred to the NSA.
• File A from the USB device replaces file A on the NSA.
• File C on the NSA is deleted.

USB <-> NSA

When you synchronize files in both directions simultaneously, both storage devices transfer unique files to one another. Files with the same file name are synchronized according to their modification date/time. The difference in modification time between the two files has to be greater than five minutes. More recently modified files overwrite the older ones during synchronization.

The following figure illustrates how synchronization works when you synchronize files in both directions simultaneously.

• A copy of file C from the USB device is transferred to the NSA.
• A copy of file D from the NSA is transferred to the USB device.

Package Management

10.1 Overview

Package Management can be used to set up more useful applications in your NSA. The NSA can download multiple packages/files at once and automatically goes through all the installation steps.

10.2 What You Can Do

• Use the Package Management screen (Section 10.4 on page 220) to download and install applications from the web.
• Use the eMule screens (Section 10.5 on page 224) to configure the server, task and search settings for the eMule application.
• Use the DyDNS screen (Section 10.6 on page 240) to configure the domain name settings of your NSA.
• Use the NFS screen (Section 10.7 on page 241) to configure the Network File System (NFS) settings of your NSA.
• Use the SMART screens (Section 10.8 on page 245) to view your NSA hard disk(s) statistics and monitor their performance.
• Use the Protect screens (Section 10.9 on page 249) to configure and schedule the backup and restore jobs of your NSA.

10.3 What You Need to Know

This feature enables you to use the following applications:

• eMule - eMule is an open-source peer-to-peer (P2P) file-sharing application similar to eDonkey, which can be used to download files from the Internet. It uses the Kad protocol.
• DyDNS - This gives your NSA a domain name with a dynamic IP address. At the time of writing, this package supports accounts from the following service providers: DynDNS, NoIP, 3322, ZoneEdit, and DHS.

- Gallery - This web-based application allows your NSA to host pictures. You can upload images in your local computer or shares to this application. Use the administrator account of your NSA to log in to the Gallery console. The administrator can then create accounts for other users.

- NFS - NFS (Network File System) is a file-sharing protocol most commonly implemented on Unix-like systems.

- PHP-MySQL-phpMyAdmin - This tool can be used to manage MySQL through the web. Enter 'root' as the username and '1234' as the password to log in. This includes MySQL 5.1.30, PHP 5.2.8 and phpMyAdmin 3.1.1.

- SMART - Use S.M.A.R.T. (Self Monitoring, Analysis, and Reporting Technology) to monitor hard disks. It detects and reports the reliability of hard disks using standard indicators, enabling administrators to anticipate possible disk failures.

- SqueezeCenter - This enables you to manage a Logitech's Squeezebox device connected to the NSA.

- WordPress - This allows you to create and manage a blog. Use the NSA administrator credentials to log in. The administrator can then create accounts for other users.

- BackupPlanner - Use this to schedule and run backup jobs for files stored in your NSA to an internal drive, external storage device or to another NSA in the network.

The following applications come with their own web configurator and documentation:

• Gallery
• PHP-MySQL-phpMyAdmin
• SqueezeCenter
• WordPress

Table 66 Storage > S.M.A.R.T: Full Summary

LABEL	DESCRIPTION
ID	This is the identification number used to tag a hard disk attribute.This is standard across all S.M.A.R.T-enabled storage devices.However it depends on the storage vendor which attributes it will allow S.M.A.R.T to diagnose.
Attribute Name	This refers to an attribute of the hard disk that S.M.A.R.T can assess.Attributes describe the hard disk's physical state, performance, wear-and-tear, and so on.
Flag	This shows a code that S.M.A.R.T uses to determine the current state of the hard disk.
Value	This is a value that corresponds to the Raw Value. Compare this with the Threshold Value.S.M.A.R.T compresses the raw value(s) into a digit from 1 to 253, where 1 indicates the worst scenario while 253 indicates the best scenario.The values 100 or 200 usually represent the mean or normal value.
Worst	This is the lowest value attained by the hard disk since S.M.A.R.T started its assessment of the hard disk.
Threshold	This is the attribute's threshold value. If the attribute's current normalized value is less than or equal to the threshold, the attribute has failed. An attribute value close to or below the threshold indicates the hard drive is no longer reliable.
Type	This shows S.M.A.R.T's assessment of the hard disk.Old_age indicates end-of-product life from old-age (normal wearing out) if the attribute value is less than or equal to the threshold.Pre-fail indicate imminent hard drive failure if the attribute value is less than or equal to the threshold.Note that just because an attribute is of the Pre-fail type does not mean your hard drive is ready to fail. It only means this if the current normalized value of the attribute is less than or equal to the threshold.
Updated	This indicates when the hard drive updates the value for this attribute.Always means the hard drive updates this attribute during normal operation and during offline activities.Offline means the hard drive only updates this attribute when no one is accessing the hard drive.

Table 66 Storage > S.M.A.R.T: Full Summary

LABEL	DESCRIPTION
When Failed	This column indicates when (if ever) the attribute failed. An attribute has failed if the normalized value is less than or equal to the threshold.-: This displays if the attribute is not failing now and has never failed in the past.FAILING_NOW: This displays if the attribute's current normalized value is less than or equal to the threshold.In_the_past: This displays if the attribute's current normalized value is greater than the threshold but the worst recorded value is less than or equal to the threshold.
Raw Value	This is the attribute's unprocessed raw data. These values show exact amounts of time or numbers of attempts or errors. The meaning to the raw values is specific to the hard drive manufacturer. Table 42 on page 156 has some information about whether a higher or lower individual raw S.M.A.R.T. attribute value is better.

Backup Type	Choose the backup type that you want the NSA to implement for the backup job.Archive- This is a backup of the source folder in an archive format. Once you backup your files in the target folder, you cannot access the files individually unless you have the extracting tool used by the NSA. If there are existing files in the target folder prior to the NSA's backup job, the files remain undisturbed. You can also choose between the following types of archive:Full- The NSA does a fresh backup each time. This provides the most protection but also requires the most storage space.Incremental- The NSA backs up new or modified files from the source folder since the last backup. The first backup is a full backup. You can also do a full backup after several incremental backups. Enter how many incremental backups the NSA runs before it performs a full backup of the source folder. You must keep the latest full backup to be able to restore the files later.Synchronization- This does a backup of individual files. If you use this type, you cannot use theRestorefeature of the NSA. You can also choose between the following types of synchronization:Mirror- The NSA deletes all data in the target folder before running the backup. It makes a copy of the source files.Publish- The NSA does a backup of individual files to the target folder without overwriting existing files in that folder. It makes the target folder identical to the source folder.

The following table describes the labels in this screen.

Table 70 Protect > Backup: Step 3

LABEL	DESCRIPTION
Compression	Select Yes if you want NSA to compress the files for your backup. Otherwise, choose No.In an Archive backup, compression is a method of packing computing files in a way that saves hard disk space.For a Synchronization backup (to a remote target), the source data will be compressed before the transmission to reduce the transmission time. It is used in slow networks only.
Encryption	Select Yes if you want NSA to encrypt the files for your backup. Otherwise, choose No.In an Archive backup, this means using a password to secure files.For a Synchronization backup (to a remote target), this means securing the file transfer session. However the final file stored on the remote NSA is unencrypted. This takes a long time. Make sure you really need this feature before enabling it.
Bandwidth	Restrict the bandwidth of synchronization backups to help stop them from using all of your network connection's available bandwidth. This is more important when backing up to a remote NSA or computer through the Internet.

10.12 Technical Reference

This section provides technical background information on the topics discussed in this chapter.

10.12.1 S.M.A.R.T Attributes

The following table describes some common S.M.A.R.T. attributes. If a higher or lower raw attribute value is better, it is indicated in the BETTER column. Since

S.M.A.R.T. attributes and their definitions vary by manufacturer, refer to the hard drive manufacturer for details about the attributes your hard drive supports.

Table 81 S.M.A.R.T. Attributes

ID	ATTRIBUTE NAME	BETTER	DESCRIPTION
01	Read Error Rate	Low	Shows the rate of hardware read errors. If this is not zero, there is a problem with the disk surface or the read/write heads.
02	Throughput Performance	High	This is the hard drive's general (overall) throughput performance. A decreasing value indicates a problem.
03	Spin-Up Time	Low	This is the average number of milliseconds the hard drive took for spindle spin up (from zero RPM to fully operational).
04	Start/Stop Count		The total number of spindle start and stop cycles.
05	Reallocated Sectors Count	Low	Total number of reallocated sectors on the hard drive. When the hard drive detects a read/write/verification error, it marks the sector as “reallocated” and transfers the data to a specially reserved (spare) area. The process is also known as remapping with “reallocated” sectors known as remaps. The more sectors the hard drive has to reallocate, the slower read and write speeds become.
06	Read Channel Margin		This is the margin of a channel when it reads data.
07	Seek Error Rate	Low	This is the rate of the magnetic heads’ seek errors. A failure in the mechanical positioning system, such as servo damage or a thermal widening of the disk, results in seek errors. An increasing number of seek errors indicate the condition of the disk surface and the mechanical subsystem are worsening.
08	Seek Time Performance	High	This is an average performance indicator for the seek operations of the magnetic heads. Mechanical subsystem problems cause this value to decrease.
09	Power-On Hours (POH)	Low	This is how many hours the hard drive has been in a power-on state. The raw value lists the total number of hours (or minutes, or seconds depending on the manufacturer).
10	Spin Retry Count	Low	This is the total number of spin start retry attempts. This is the number of attempts to spin up to fully operational speed the hard drive has made when the first attempt did not succeed. An increase in this value is an indicator of hard disk mechanical subsystem problems.
11	Recalibration Retries	High	This is the number of times recalibration was requested when the first attempt did not succeed. A decrease in this value is an indicator of hard disk mechanical subsystem problems.
12	Device Power Cycle Count		This is the number of times the hard drive has gone through a full power on and power off.
13	Soft Read Error Rate	Low	This is the number of uncorrected read errors the hard drive has reported. If this is not zero, back up your data.
190	Airflow Temperature	Low	This indicates the temperature of the airflow measured by a Western Digital hard drive.
190	Temperature Difference from 100	High	This indicates the value of 100 - the temperature in degrees Celsius. Manufacturers can set a minimum threshold that corresponds to a maximum temperature.
191	G-sense error rate	Low	This is the number of mistakes caused by impact loads.
192	Power-off Retract Count	Low	This is how many times the heads are loaded off the media.
193	Load/Unload Cycle	Low	This is the number of load and unload cycles into head landing zone position.
194	Temperature	Low	This is the hard drive's internal temperature.
195	Hardware ECC Recovered	High	This is the time between ECC (Error Correction Code)-corrected errors.
196	Reallocation Event Count	Low	This is the total number of reallocation (remap) operations. The raw value is the total attempts to move data from reallocated sectors to a spare area. Successful and unsuccessful attempts are both included.
197	Current Pending Sector Count	Low	This is the number of unstable sectors awaiting reallocation. If the sector is later successfully written or read, this value decreases and reallocation is not performed. Only failed write attempts cause a reallocation, not read errors. This can be difficult to test since only direct I/O writes to the disk cause reallocations, not cached writes.
198	Uncorrectable Sector Count	Low	This is the number of errors reading or writing a sector that were not correctable. An increase in this value is an indicator of disk surface defects or mechanical subsystem problems.
199	UltraDMA CRC Error Count	Low	This is the number of data transfer errors through the interface cable according to the ICRC (Interface Cyclic Redundancy Check).
200	Write Error Rate / Multi-Zone Error Rate	Low	This is the total number of errors in writing sectors.
201	Soft Read Error Rate	Low	This is the number of read/write head off-track errors. If the value is not zero, make a backup.
202	Data Address Mark Errors	Low	This is the number of data address mark errors. This could also be a different, manufacturer-specific attribute.
203	Run Out Cancel	Low	This is the number of ECC (Error Correction Code) errors.
204	Soft ECC Correction	Low	This is the number of errors corrected by software ECC (Error Correction Code).
205	Thermal Asperity Rate (TAR)	Low	This is the number of thermal asperity errors. Thermal asperity is a read signal spike caused by sensor temperature rise due to touching the disk surface or contaminant particles.
206	Flying Height		This is the height of the hard drive's read/write heads above the disk surface.
207	Spin High Current		This is the quantity of high current used to spin up the drive.
208	Spin Buzz		This is the number of buzz routines to spin up the drive. When the arm holding the read/write heads is stuck, the motor driving it tries to oscillate the arm to free it. This causes an audible vibration.
209	Offline Seek Performance		This is the hard drive's seek performance during offline operations. Offline operations are tests the drive does itself as opposed to those that an external diagnostic tool has it do. Seek performance is how quickly the drive moves from track to track.
220	Disk Shift	Low	This is how far the disk has moved relative to the spindle (this kind of shift is usually due to shock).
221	G-Sense Error Rate	Low	This is the number of errors that have resulted from external vibration and shock.
222	Loaded Hours		This is how long the hard drive has operated under data load (this requires movement of the magnetic head armature).
223	Load/Unload Retry Count		This is how many time the magnetic head has changed position.
224	Load Friction	Low	This is resistance caused by friction in mechanical parts during operation.
225	Load/Unload Cycle Count	Low	This is the total number of load cycles.
226	Load 'In'-time		This is the total time that the magnetic heads actuator has had a load (not been in the parking area).
227	Torque Amplification Count	Low	This is the number of attempts to compensate for variations in platter speed.
228	Power-Off Retract Cycle	Low	This is how many times the magnetic armature was automatically retracted because the power was cut.
230	GMR Head Amplitude		This is the amplitude of thrashing (or the distance of repetitive forward and reverse head motion).
231	Temperature	Low	This is the hard drive's temperature.
240	Head Flying Hours		This is the total time that the head has been positioning.
250	Read Error Retry Rate	Low	This is the number of errors in reading from the disk.

Auto Upload

11.1 Overview

This chapter discusses the features in the Auto Upload screens.

The auto upload feature uploads media files stored in the NSA to the Flickr and/or YouTube sharing websites. Besides web publishing and media server, auto upload is another convenient way to share media files with your friends and family. You can link the NSA to your Flickr and/or YouTube account and select shares for the NSA to upload. The NSA uploads the media files stored in the specified shares to your Flickr and/or YouTube account. When you add new files to the specified shares, the NSA also automatically uploads the new files to your Flickr and/or YouTube account.

11.2 What You Can Do

• Use the Flickr/YouTube screen (Section 11.4 on page 274) to upload photos and videos to your Flickr and YouTube accounts.
• Use the FTP Uploadr screen (Section 11.5 on page 284) to upload files to FTP servers.

11.3 What You Need to Know

FTP

File Transfer Protocol (FTP) is a file transfer service that operates on the Internet. A system running the FTP server accepts commands from a system running an FTP client. FTP is not a secure protocol. Your file transfers could be subject to snooping.

FTPES (File Transfer Protocol over Explicit TLS/SSL)

File Transfer Protocol over Explicit TLS/SSL (FTPES) is a file transfer service that uses TLS (Transport Layer Security) or Secure Socket Layer (SSL) for secure transfers across the Internet.

Maintenance Screens

15.1 Overview

This chapter discusses the Maintenance screens. The Maintenance screens allow you to manage system configurations.

15.2 What You Can Do

• Use the Power screen (Section 15.3 on page 310) to configure power settings for the NSA, including power saving, UPS, power on/off during power failure and power on/off schedule.
• Use the Log screen (Section 15.4 on page 314) to check the system's logs.
• Use the Configuration screen (Section 15.5 on page 318) to backup or restore the NSA configuration file.
• Use the SSL screen (Section 15.6 on page 319) to configure HTTPS and the NSA's SSL certificate.
• Use the Firmware Upgrade screen (Section 15.7 on page 322) to upload new firmware.
• Use the Shutdown screen (Section 15.8 on page 323) to restart or shut down your NSA.

15.3 The Power Screen

Use this screen to manage power settings for the NSA, including power saving, UPS, power on/off during power failure and power on/off schedule.

Click Maintenance > Power to display the following screen.

Figure 173 Maintenance > Power

Maintenance - Power Power Management Turn off hard disk(s) 3 minutes Minimum UPS Capacity Minimum UPS Capacity 50 % Note: • This feature will not work now because there is no UPS control cable connected. • The NSA automatically shuts down if the UPS's remaining charge gets down to this level. Power On After Power Failure • Keep Former Status If the system was on when the power failed, it restarts automatically when the power is restored. If it was off, it stays off. • Always Power On The system restarts automatically when the power is restored. • Always Power Off The system will not restart after power failure. You must press the power button manually to restart it. Power On/Off Schedule Enable Power Control Schedule Edit Apply Reset

The following table describes the labels in this screen.

Table 100 Maintenance > Power

LABEL	DESCRIPTION
Power Management
Turn off hard disk(s)	Enter the number of minutes the NSA will sit idle before spinning the hard disks down to sleep. The default power-off time is 3 minutes.
Minimum UPS Capacity
Minimum UPS Capacity	When you use an APC Uninterruptible Power Supply (UPS) with a USB connection to the NSA, the NSA shuts itself down if the APC UPS's battery charge gets down to the percentage you specify in this field. This allows the NSA to shut down properly and avoid data loss caused by a power failure when the UPS stops supplying power.A setting around 50% is recommended. A setting close to 100% is not recommended since it would cause the NSA to shut down whenever the UPS is charging. A setting close to 0 is also not recommended since the UPS would not have enough power to allow the NSA to shutdown properly.
Power On After Power Failure	Select an option to set whether or not the NSA restarts when the power is restored after a power failure.
Keep Former Status	Select this option to have the NSA automatically restart only if it was operating when the power failed. The NSA remains off if it was already off when the power failed.
Always Power On	Select this option to keep the NSA operating as much of the time as possible. The NSA restarts automatically even if it was turned off when the power failed.
Always Power Off	Select this option to keep the NSA from automatically restarting when the power is restored after a power failure. This is a computer's "traditional" behavior. Select this if you have other servers such as a domain controller or DNS server that you want to start or check after a power failure before the NSA turns on.
Power On/Off Schedule
Enable Power Control Schedule	Select this option to have the NSA turn itself off and on or reboot according to the schedules you configured.Click Edit to go to the screen where you can configure the power control schedules.Refer to Section 15.3.1 on page 312 for this screen.

Protecting Your Data

16.1 Overview

This chapter compares the different ways of protecting data on the NSA and explains how to use backup management software included on the CD.

16.2 Protection Methods

There are a variety of ways to protect your data on the NSA. Below is a summary table of what can be done in each situation.

Table 114 Overview of Protection Methods

SITUATION	ACTION
Unexpected NSA behavior after configuration changes	Back up the NSA configuration file before you make major configuration changes.
Need to transfer data from your computer to the NSA after volume(s) have been created	Use the Memeo Autobackup program.
Data infected by virus	Use anti-virus software on your computer to scan files before saving them onto the NSA. Although this may be slow so you may want to schedule it to occur while no one is using the NSA.Use a firewall with anti-virus capability on your network.
Hard drive malfunction.	Use RAID.
NSA malfunctionNetwork downNatural disaster such as a fire or earthquake occurs where your NSA is located	Back up data to another NSA or external USB hard drive.

The following sections describe these methods in more detail. See Section 7.6.3 on page 157 for more information on RAID.

16.3 Configuration File Backup and Restoration

Use the Maintenance > Configuration menus to create a file of your NSA configurations such as passwords, shares and volumes created, network settings and so on. If you're going to do some major configuration changes, then it is advisable to create a configuration backup file. If things go wrong after you make the configuration changes, you can always go back to the previous configuration by restoring an earlier configuration file.

If you forgot the NSA password, then use the RESET button (see Section 17.4.1 on page 344) to return the NSA to the factory default configuration.

Note: Configuration File Backup and Restoration does not affect data (your files and folders), volumes on the NSA.

16.4 Memeo Autobackup

Use the Memeo Autobackup software (included on the CD) on your computer to schedule and manage backups. You can backup from your computer to the NSA. You can also backup from one NSA on your network to another. You can set the Memeo Autobackup software to automatically back up files from your computer to the NSA whenever you modify the files.

Install the included DLNA-compliant Memeo Autobackup software on your Windows XP or later computers to let them browse and play files stored on the NSA.

Note: The Memeo Autobackup program uses the same network port as the NAS Starter Utility to discover the NSA. To avoid a port conflict, do not run the Memeo Autobackup program at the same time as the NAS Starter Utility.

Use the Memeo Autobackup software included on the CD to automatically back up selected files from your computer to the NSA whenever you modify the files.

Memeo Autobackup works with Windows XP, Windows Vista, and both the 32 bit and 64 bit versions of Windows 7.

16.4.1 Memeo Autobackup Installation and Setup

Note: The Memeo Autobackup program uses the same network port as the discovery utility to discover the NSA. To avoid a port conflict, turn off the discovery utility before using Memeo Autobackup.

1 Since a computer restart is required, close your other files and programs before installing the Memeo Autobackup software.
2 Insert the included CD into your CD-ROM drive. Click the Tools icon in the screen that displays. Then click Memeo Instant Backup Software.

Note: If this screen does not display, use Windows Explorer (My Computer) to go to the CD-ROM (commonly drive D). Double-click setup.exe.

17.2 Power, Hardware, Connections, and LEDs

The NSA PWR LED does not turn on (no LEDs are on).

- Make sure the NSA is turned on.

• Make sure you are using the power adaptor or cord included with the NSA.
• Make sure the power adaptor or cord is connected to the NSA and plugged in to an appropriate power source. Make sure the power source is turned on.
• Turn the NSA off and on.
• If the problem continues, contact the vendor.

An HDD LED is off.

The HDD LED is off when the NSA cannot detect a hard drive in the drive bay. Replace or install a hard drive. See Installing or replacing a hard disk.

An HDD LED is red.

Red means that the NSA detected an error on the hard drive (like a bad sector for example). The NSA automatically tries to recover a bad sector, but the LED stays red until the NSA restarts. Even if the hard drive still functions, it is recommended that you replace it since errors are a sign that the hard drive may fail soon. See Installing or replacing a hard disk.

Installing or replacing a hard disk.

Do not remove or install a hard disk while the NSA is turned on. The NSA must be turned off before you remove or install the hard disk.

1 Turn the NSA off, remove the front panel and make sure:

• there is a SATA I or SATA II (3.0 Gbit/s) compatible hard disk installed.
• the hard disk is installed correctly in the disk bay. Push the disk back into the NSA disk bay until the hard disk is fitted snugly inside the NSA (see the NSA Quick Start Guide and Section 7.2.1 on page 148).
• the hard disk could be faulty. Try a different hard drive or test the original hard disk in a different NSA or computer.

2 If you had to replace the drive, turn on the NSA and go to the Storage screen.

• If you have a RAID I volume click the Repair icon next to the new drive.

• If you are using RAID 0 you will need to recreate the whole volume. All of your data is lost.

• If you are using a single-disk JBOD volume, you need to create a new volume on the new drive.

• If you are using a two-disk JBOD volume, you need to create a whole new volume on both drives.

The LAN LED (by the LAN port) is off.

• Make sure the Ethernet cable is connected properly to the NSA and connected to another (Ethernet) device. Make sure the other device is turned on. If it's connected directly to a computer, make sure that the computer network card is working (ping 127.0.0.1 on the computer).
• Use another Ethernet cable. If you're connecting to a Gigabit Ethernet, make sure you're using an 8-wire Ethernet cable.
• If the problem continues, contact the vendor.

See Section 1.3 on page 23 for a description of NSA LEDs.

The NSA turns off or reboots by itself.

Check the Power Management screen. This is where you configure power settings for the NSA, including power saving, UPS, power on/off during power failure and power on/off schedule. The NSA may be set to turn off under certain conditions.

A power failure occurred while the NSA is downloading files.

• If power failure occurs during the active download period, the NSA will verify whether the downloaded files were damaged.
• If a file is corrupted, the NSA will download the file again.
• If the file is intact but not completely downloaded, the NSA will resume the download task after it restarts.

17.3 NAS Starter Utility

The NAS Starter Utility cannot discover my NSA.

• Close the NAS Starter Utility and reopen it.
• Check your hardware connections and make sure they are set up correctly.
• Only one instance of the NAS Starter Utility can run on your computer. Make sure you close any duplicate windows for this application.
• Wait for the SYS LED to stop blinking before clicking Discover.
• Confirm that the computer running the NAS Starter Utility has a network connection. See the section on the NSA's LAN connection for related information.
• The computer running the NAS Starter Utility can only discover NSAs in the same subnet. NSAs connected to the same switch or router as your NAS Starter Utility computer are usually in the same subnet unless the router is doing subnetting or the switch is implementing VLAN.
• The Memeo Autobackup program uses the same network port as the NAS Starter Utility to discover the NSA. To avoid a port conflict, do not run the Memeo Autobackup program at the same time as the NAS Starter Utility.

I was able to access the NSA on a previous attempt but I cannot access the NSA anymore.

If you enable jumbo frames on the NSA in a network that does not support them, you will lose access to the NSA. If this occurs, you will have to restore the factory default configuration. The reset process does NOT affect the volume settings, nor data stored on the NSA. Push the RESET button on the NSA's rear panel and release it after you hear a beep (Section 17.4.1 on page 344).

I have at least two NSAs in my network, how do I identify which one I want to configure in the NAS Starter Utility screens.

If you have several NSAs connected to your computer/network, give each a unique name. You may have to disconnect all but one and use the NAS Starter Utility to rename it. Then connect another NSA and rename it and continue to connect and rename the NSAs one-by-one until they are all connected and each has a unique name.

Alternatively, if you have a DHCP server on your network and you can access it's list of assigned IP addresses, you could see which IP address belongs to which NSA. You can check the MAC address of your NSA by checking the attached sticker in the device housing.

17.4 NSA Login and Access

I forgot the server name of the NSA.

• The default server name is nsa221.
• Use the NAS Starter Utility to discover your NSA. If you have admin privileges, you can directly change the IP address of the NSA using the NAS Starter Utility.
• If the server name has changed and you don't have the NAS Starter Utility, see Section 17.4.1 on page 344 to use the RESET button to return the default setting.

I cannot get to the NSA login screen.

• Use the NAS Starter Utility to discover your NSA. If you have admin privileges, you can directly change the IP address of the NSA using the NAS Starter Utility.
• Make sure you have used the NAS Starter Utility to initialize your NSA.
• If you used the RESET button, the NSA may have a new IP address. Close and reopen the NAS Starter Utility to discover the NSA.
• Make sure the NSA is turned on.
• If you are trying to login directly by typing the server name into your web browser's address field, make sure you are using the correct server name as the web site address.
• The default server name is nsa221, if you have changed the server name, use the new one.
• If the server name has been changed and you do not know the new server name, see the troubleshooting suggestions for I forgot the server name of the NSA.
• If it still doesn't work, try using the NAS Starter Utility.

• Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide and Section 1.3 on page 23.

• By default, the NSA gets an IP address automatically. The NSA assigns itself an IP address if no device assigns one. If your computer is also set to get an IP address automatically, the computer and the NSA can both assign themselves IP addresses and communicate. See Section 8.4 on page 163 if you need to configure the NSA with a static IP address.

• Make sure your computer's IP address is in the same subnet as the NSA's IP address. You can use the NAS Starter Utility to find the NSA's IP address. See Appendix A on page 369 for how to change your computer's IP address. Skip this if you know that there are routers between your computer and the NSA.
• Ping the NSA from your computer. Make sure your computer's Ethernet adapter is installed and functioning properly. In a (Windows) computer, click Start, (All) Programs, Accessories and then Command Prompt. In the Command Prompt window, type "ping" followed by the NSA's IP address (use the NAS Starter Utility to find the NSA's IP address if you don't know it) and then press [ENTER].
• Make sure you are using Internet Explorer 6.0 (and later) or Firefox 1.07 (and later).
• Make sure your Internet browser does not block pop-up windows and has JavaScript and Java enabled. See Appendix B on page 385. With Internet Explorer 6, you may also have to enable scripting of safe ActiveX controls. See Section 17.4.2 on page 345.

17.4.1 Reset the NSA

If you forget your password or cannot access the web configurator, use the RESET button at the rear of the NSA. When you use the following reset procedure, the system name and admin password are returned to the factory defaults.

You may need to close and re-open the NAS Starter Utility to discover the NSA. This is because the NSA automatically re-acquires IP address information, so its IP address may change since. If no IP address information is assigned, the NSA uses Auto-IP to assign itself an IP address and subnet mask. For example, you could connect the NSA directly to your computer. If the computer is also set to get an IP address automatically, the computer and the NSA will choose addresses for themselves and be able to communicate.

1 Press and hold the RESET button (for about two seconds) until you hear a beep, and then release it.

2 The NSA automatically restarts to complete the reset.

I forgot the password.

• The default password is 1234.

- If you have changed the password and forgotten it, you will have to reset the NSA.

17.4.2 Enabling Scripting of Safe ActiveX Controls

If pages of the web configurator do not display properly in Internet Explorer, check that scripting of safe ActiveX controls is enabled.

1 In Internet Explorer, click Tools, Internet Options and then the Security tab.

Figure 192 Internet Options: Security

2 Click the Custom Level... button.
3 Under Script ActiveX controls marked safe for scripting, make sure that Enable is selected (the default).

4 Click OK to close the window.

Figure 193 Security Settings - Script Safe ActiveX Controls

Security Settings Settings: Run ActiveX controls and plug-ins Administrator approved Disable Enable Prompt Script ActiveX controls marked safe for scripting Disable Enable Prompt Downloads File download Disable Enable Font download Reset custom settings Reset to: Medium Reset OK Cancel

I can see the login screen, but I cannot log in to the NSA.

• Make sure you have entered the username and password correctly. The default username is admin, and the default password is 1234. These fields are case-sensitive, so make sure [Caps Lock] is not on.
• Turn the NSA off and on.
• If this does not work, see Section 17.4.1 on page 344 to reset the device.

I cannot see the multi-language web configurator screens while using Internet Explorer.

Use Section 17.4.2 on page 345 to enable the scripting of safe ActiveX controls.

The Web \Configurator logs out by itself.

The web configurator management session automatically times out if it is left idle for 15 minutes. Simply log back into the NSA if this happens to you.

17.5 I Cannot Access The NSA

I cannot access a share.

• Check that the NSA is turned on and connected to the network. Try to ping the NSA or use the NAS Starter Utility to discover it.
• Make sure you have used the NAS Starter Utility to initialize your NSA. See Chapter 2 on page 27 for more information.
• Check that you entered your login name and password correctly.
• Check that the share exists and check its access settings.
• Check if the shared folder is a subfolder of another (parent) share. Check that the parent share's access rights do not conflict with the subfolder share. It is recommended that you do not create subfolder shares.
• Check if there are any existing mapped network drives to the NSA. You may need to disconnect existing mapped network drives as a new mapped network drive connection may use (different) previously-saved login information. To do this, open Windows Explorer and click Tools > Disconnect Mapped Network Drives.
• Check that the volume in which the share resides, exists and is not down or degraded. If it is down or degraded, see Section 17.2 on page 339.
• Make sure you have the client for Microsoft networks installed and enabled in your network connection's properties.
• In Windows XP or 2000, click Start > Settings > Control Panel > Network Connections (Network and Dial-up Connections in Windows 2000/NT) > Local Area Connection > Properties.
• Check that Client for Microsoft Networks is in the list of components and has its check box selected.

17.6 Users Cannot Access the NSA

A local user cannot access a share

• Check that the NSA is turned on and connected to the network. The local user should try to ping the NSA or use the NAS Starter Utility to discover it.
• The local user should check that he entered his login name and password correctly.

• Check if the share exists and has the correct access settings for this user.

• Check the Access Control List (ACL) of read/write permissions associated with specific files and/or folders. Account names added to the list are linked to the files and folders that they are allowed to access, along with what kinds of actions they are allowed to perform with those files and folders (delete, move, rename, and so on).

• The user's computer may already be connected to another of the NSA's shares using a different user name and/or password. This can happen without the user realizing it if the user's computer automatically connects to a share at logon. Right-click any other connected shares and click Disconnect. Then re-attempt to connect to the desired share.
• Check if the share has an ANONYMOUS or EVERYONE access right. If the user is already logged into a share using her username and password, she will NOT be able to access a share that has ANONYMOUS FTP only access rights (as these require 'no login'). In this case she should log out and try to access the share again without logging in. See Section 9.4 on page 176 for more details.
• Check if the shared folder is a subfolder of another (parent) share. Check that the parent share's access rights do not conflict with the subfolder share. It is recommended that you do not create subfolder shares.
• Check if the user belongs to a group with conflicting access rights. DENY always takes precedence. If you allow a user FULL access to a share but set his group to DENY, then he will NOT be able to access the share.
• The local user should check if there are any existing mapped network drives to the NSA. He may need to disconnect existing CIFS connections as new CIFS connection may use previously-saved login information that may be different to NSA login.
• Check that the array in which the share resides, exists and is not down or degraded. If the array is down or degraded, see Section 17.2 on page 339.
• If the user is using DFS links, then he can only access the NSA using CIFS and not FTP.
• Check that the share has not been disabled.

I cannot import domain user or user group information even though testing of the connection to the domain controller is OK.

- Check the NSA's DNS setting. The DNS server the NSA is using must be able to resolve the domain controller's address. If the domain controller uses a private IP address, the NSA needs to use a private DNS server. If the domain controller uses a public IP address, the NSA needs to use a public DNS server.

- Leave the domain and re-join it.

A domain user can't access a share.

In addition to the checks listed previously for local users, check that the domain controller is turned on and connected to the network.

A user can access a share but cannot access individual folders or files within the share.

- Check the Access Control List (ACL) of read/write permissions associated with the share's specific files and/or folders. Account names added to the list are linked to the files and folders that they are allowed to access, along with what kinds of actions they are allowed to perform with those files and folders (delete, move, rename, and so on).

17.7 External USB Drives

The COPY LED is red.

Copying files from a USB device failed. The USB device may not be compatible with the NSA. Try save the files onto a computer and then from the computer to the NSA (through the network connection).

17.8 Firmware

I want to know the firmware version on the NSA.

Go to the Status screen. The Firmware field shows you the current firmware version running.

17.9 File Transfer

I want to transfer my file(s) from my local computer or storage device to the NSA.

- After you initialize your hard disk, you can directly access the folders in your NSA and transfer files in the same way you transfer files in your local computer:

1 On your Windows computer, click Start > Run or open a web browser.
2 Enter \nsa221 (default) or the Server Name you assigned the NSA. This shows you the folders in the NSA.
3 Use drag-and-drop or copy-and-paste to transfer files over to your NSA.

- Use the COPY/SYNC button to transfer files from an external (USB) storage device to the NSA.

- If the file you want to transfer is less than or equal to 2GB, you can use the NSA Starter Utility's zPilot screen (see Section 2.6 on page 41).

I want to transfer my file(s) from the NSA to my local computer or storage device.

- After you initialize your hard disk, you can directly access the folders in your NSA and transfer files in the same way you transfer files in your local computer:

1 On your Windows computer, click Start > Run or open a web browser.
2 Enter \nsa221 (default) or the Server Name you assigned the NSA. This shows you the folders in the NSA.
3 Use drag-and-drop or copy-and-paste to transfer files from your NSA to your local computer's folder or your storage device.

- You can download the files from your NSA. Just click on the file(s) in the Share Browsing screen (Section 3.4.3 on page 55). Your computer will prompt you for the location where you want to save the file.

17.10 Networking

I want to control who can access my folder(s)/file(s).

• If you are an administrator, you can configure a user's access rights. Use the Shares screen (Section 14.3 on page 300) to do this.
• If you enabled Web Publishing for a folder, anyone on your network can play the media files in the published shares. No user name and password or other form of security is used. The media server is enabled by default with the video, photo, and music shares published.

One of the computers in my network cannot use the printer I connected to the NSA.

• You must install the printer driver on each computer that will use the printer.
• Check Section 17.4 on page 343 and check for related connectivity issues.

17.11 Some Features' Screens Do Not Display

Many NSA features require a valid internal volume.

Features like the print server, download service, broadcatching, FTP and Windows/CIFS access will not work without a valid internal volume. Make sure you have a volume on an internal disk and that the volume is in the healthy state.

• Install an internal disk if one is not installed yet or has failed. See the Quick Start Guide for how to install an internal disk.
• Create a new volume if you do not have one on the internal disk yet.
• Make sure the volume on the installed internal disk is in a healthy state.

I cannot use some applications in the Web Configurator.

• The firmware installed in your NSA includes the features mentioned in Section 3.5.2 on page 64. This does not include the applications you can install using the Package Management screen.
• You can use the Package Management screen (Chapter 10 on page 219) to install more applications from a web location (specified in the firmware) to your NSA.
• If you have installed the application and can see the application's configuration screen but still cannot use it, check that you have Enabled the application.

17.12 Media Server Functions

I set the media server function to publish a folder, but some of the files in the folder do not display in the list on the media client.

Files with formats that are not supported on the media server may not display in the list. See Section 18.4 on page 366 for the file formats that the media server supports.

I published a folder with the media server function, but the media client does not play some of the files (or does not play them properly).

1 Files with formats that are not supported on the media server may not display in the list. See Section 18.4 on page 366 for the file formats that the media server supports.
2 If you are using media client software, you may need to install codecs on your computer. Since the media client software uses your computer's installed codecs, files do not play if the required codec is not installed on your computer.
3 The media client may not support the file's format.

iTunes does not display the names of all the music or video files I just put on the NSA.

1 Make sure the files are a format supported by iTunes. See Section 18.5 on page 367.
2 Go to Applications > Media Server. Make sure the share containing the music and video files is published and the iTunes server option is enabled.

3 If an iTunes client is connected, the NSA's iTunes server function scans the published media server folders for files every three minutes. Leave iTunes connected to the NSA for three minutes. Then use the NSA's eject button (as shown next) to disconnect.

5 Another way to get the NSA's iTunes server function to scan the published media server folders for files is to go to Applications > Media Server and disable and re-enable the iTunes server option. If you uploaded many files, it may take awhile for the NSA to find and list all of them. Then try reconnecting your iTunes client.

I cannot use iTunes to play files located on my NSA.

1 Make sure the files are a format supported by iTunes. See Section 18.5 on page 367.
2 If you have files from the iTunes Store that use DRM, you need to use your Apple account ID and password to authorize other computers to play the files. Apple permits you to authorize up to five computers at a time. To authorize a computer, open iTunes and click Store > Authorize Computer.
3 If you are connecting through a NAT router, make sure that TCP port 3689 and UDP port 5353 are open for traffic on both the server and the client and all points in between (especially the NAT router). If your router includes a firewall, make sure it also allows TCP port 3689 and UDP port 5353 traffic.

17.13 Download Service and Broadcasting Functions

The download list or broadcatching items are missing after I removed a hard drive.

The NSA's download and broadcasting lists are stored on the system volume. If you have two JBOD volumes, it is possible to remove one and still use the other. However if you remove the system volume, you may lose the download and broadcasting lists. With two JBOD volumes, the hard disk that was installed first is usually the system volume.

The channel I added in the Broadcasting screen is active but no files are downloaded to the NSA.

Check the Download Policy for that channel (see Section 9.8.1 on page 196). It may be set to manual download. You can configure your NSA to download all items or only new items automatically once the channel is updated.

I cannot find the download files.

By default, the Download Service and Broadcasting features store downloaded files as follows:

• BitTorrent jobs are stored in /*/incoming (where '*' is a folder that you have set.)
• HTTP/FTP jobs are stored in /* (where '*' is a folder that you have set.)
• All jobs triggered by RSS channels create the subfolder in /* using the channel name where it store all files downloaded from that channel (where ‘*’ is a folder that you have set.)

Check your Preferences in the Download Service (Section 9.6 on page 179) and Broadcatching (Section 9.8 on page 194) screens to know or configure where downloaded files are stored.

17.14 Web Publishing

A web-published share cannot be accessed by web browser from the Internet.

• Make sure the person trying to access the share is using the correct web address (and port number if the NSA's web publishing feature is not using port 80). See page 213 for details.
• Make sure the publishing feature is turned on and the share is in the list of published shares.
• Make sure the person trying to access the share is using Internet Explorer 6.0 (and later) or Firefox 1.07 (and later).
• You need to use a public address to access the NSA's web-published shares from the Internet. If your NSA uses a private IP address, use the public IP address of your Internet gateway (firewall) and configure NAT or port forwarding on your Internet gateway and possibly firewall rules in order to let people access the NSA's web-published shares from the Internet.
• Make sure the firewall's public IP address is static or that the firewall uses a Dynamic Domain Name (DDNS).
• Web publishing uses TCP protocol and the port number you specify. Make sure there is not another service using TCP protocol with the same port number. See Appendix C on page 395 for a list of common services and their associated protocols and port numbers.
• If Firefox access to the share does not work, check that you did not set the Web publishing feature to use one of the following ports. (Firefox blocks these ports by default.)

• Make sure your ISP allows you to run a server and is not blocking the port number of the NSA's web publishing feature.

17.15 Auto Upload

The NSA does not automatically upload files to Flickr or YouTube.

1 Make sure the NSA is connected to the Internet. See Section 8.4 on page 163 for details about testing network connections.
2 Click Maintenance > Log to check the NSA's log for a message about the file.

2a If the log message displays "no such file or directory", the file may have been removed from the NSA. Make sure the file still exists in the watch folder.
2b If the log message displays "filename is queued", the file may still be waiting for auto upload. Check the grace period setting in the service's Configuration screen. You can set a smaller grace period to shorten the queue time.
2c If you cannot find any log messages about the file:

• Make sure the Folder Watch List includes the folder containing the file. You can upload the file to the watch folder again.
• Make sure the file's format is supported by Flickr or YouTube. You can find the supported file extensions in the Folder Watch List.

2d If the log message displays "not authorized yet", check if you can enter the NSA's Configuration screen for the service. If you changed the password of your Flickr or YouTube account, you cannot access the service's Configuration screen, and the NSA cannot auto upload files. Make sure you also update the account information in the NSA.

3 Make sure the file size does not exceed the limit imposed by the service. At the time of writing, Flickr restricts the file size to 10 MB, and YouTube restricts the file size to 100 MB.
4 Make sure you did not exceed the service's upload quota. Flickr and YouTube have different policies about how much you can upload within a certain period, for example, 100 MB/week.
5 The NSA may have temporarily failed to connect to the service. You can upload the file to the watch folder again.

17.16 Package Management

The NSA won't install the package(s) I selected in the Package Management screen.

• The web location of the package may be undergoing maintenance. Try again at a later time. Upgrade the firmware of the NSA.
• If a new firmware is available, do an upgrade and try installing the package(s) again.

The eMule Search screen does not work.

You need to be connected to an eMule server before you can use the Search screen. Wait for the NSA to connect to a server before configuring the Search screen.

I want to know how my hard disk is performing.

Use S.M.A.R.T. (Self Monitoring, Analysis, and Reporting Technology) to monitor hard disks. It detects and reports the reliability of hard disks using standard indicators, enabling administrators to anticipate possible disk failures. Go to the Package Management screen to install the S.M.A.R.T. application.

17.17 Backups

I cannot make a backup.

• Check that enough space is available on the external disk. If there isn't you may need to purge older backups or delete other files on the backup USB disk or NSA (see Section 10.9 on page 249).
• If you are using BackupPlanner (Section 10.10 on page 249):
• You can look at the Backup screen's Last Run Result display.
• If you're backing up to another NSA, another NSA, or a computer, check that it allows the NSA to write files to it. For a synchronization backup, the target must be another NSA or another compatible model.
• Check that the NSA is not performing another backup job. Scheduler queues backups when a different backup is already going on at the time a backup is scheduled.

The backup does not run at the time configured.

• Check that the correct time is configured on the NSA.
• Check that the NSA is able to access the time server from which it gets the time; see Section 6.5 on page 143.

Product Specifications

See also Chapter 1 on page 21 for a general overview of the key features.

18.1 Physical Features

These are the main external physical features.

18.2 Firmware Features

These are some of the main firmware features of the NSA.

Table 117 Firmware Features

DLNA Server	The NSA is a DLNA-compliant media server that lets DLNA-compliant media clients play video, audio, and photo content files stored on the NSA.
RAID File Storage	Use RAID 1 if you have two drives and want to mirror primary data to the second drive. If one drive fails, replace it and then re-synchronize to recover all data.
User Passwords	Configure a password for an individual User to restrict access to the NSA.
Client Support	Data can be shared among all Windows, Mac, Linux, and UNIX users that have FTP client software or CIFS file sharing support (such as Samba for Linux and UNIX users).The NSA is also a DLNA-certified media server that lets DLNA-compliant media clients play video, audio, and photo content files stored on the NSA.
HTTP and HTTPS	Access the NSA using a regular web connection (HTTP) or secure web connection (HTTPS).
DHCP (Dynamic Host Configuration Protocol)	DHCP (Dynamic Host Configuration Protocol) allows the NSA to obtain an IP address and subnet mask at start-up from a centralized DHCP server. Alternatively, you can give the NSA a static IP address and subnet mask.
Full Network Management	The embedded web configurator is an platform-independent web-based utility that allows you to easily access the NSA's management settings.
Hard Disk Drive Power Saving	If a hard disk inside the NSA is idle for six minutes, the NSA puts it to sleep until you use it again.
Firmware Upload and Configuration File Management	Upload new firmware to the NSA using the web configurator. You can also back up and restore the NSA configuration file containing all its settings to/from your computer.
NAS Starter Utility	Use the NAS Starter Utility from a Windows computer to find NSA(s) in your network, access the NSA login page, change its IP address configuration or map to a Windows network drive.
Memeo Autobackup	Memeo Autobackup is a tool for Windows users to create backups of data stored on their Windows computers to an NSA. This software is included on the CD.
Time and Date	Configure a time server and set a time zone for your NSA to show the correct times in logs.
Auto Upload	The auto upload feature uploads media files stored in the NSA to the Flickr and/or YouTube sharing websites. It is a convenient way to share media files with your friends and family. You can link the NSA to your Flickr and/or YouTube account and select shares for the NSA to upload. The NSA uploads the media files stored in the specified shares to your Flickr and/or YouTube account. When you add new files to the specified shares, the NSA also automatically uploads the new files to your Flickr and/or YouTube account.
iTunes Server	The NSA can mimic the iTunes application and download content from the iTunes server.
Package Management	Package Management can be used to set up more useful applications in your NSA, including eMule, DyDNS, NFS, SMART, BackupPlanner, Gallery, PHP-MySQL-phpMyAdmin, SqueezeCenter and WordPress. The NSA can download multiple packages/files at once and automatically goes through all the installation steps.
DyDNS	Dynamic DNS allows you to update your current dynamic IP address with a dynamic DNS service so that anyone can contact you (in NetMeeting, CUSeeMe, etc.). You can also access your FTP server or Web site on your own computer using a domain name (for instance myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an IP address that changes each time you reconnect. Your friends or relatives will always be able to call you even if they don't know your IP address.
Download Service	The NSA's download service downloads files from the Internet directly to the NSA. You do not have to download to your computer and then copy to the NSA. This can free up your computer's system resources. The download service also handles your broadcatching downloads.
Power Schedule	Use this screen to manage power settings for the NSA, including power saving, UPS, power on/off during power failure and power on/off schedule.

7 After the network card restart process is complete, make sure the Status is Active in the Network Configuration screen.

Using Configuration Files

Follow the steps below to edit the network configuration files and set your computer IP address.

1 Assuming that you have only one network card on the computer, locate the ifconfig-eth0 configuration file (where eth0 is the name of the Ethernet card). Open the configuration file with any plain text editor.

- If you have a dynamic IP address, enter dhcp in the BOOTPROTO= field. The following figure shows an example.

Figure 212 Red Hat 9.0: Dynamic IP Address Setting in ifconfig-eth0

DEVICE=eth0
ONBOOT=yes
BOOTPROTO=dhcp
USERCTL=no
PEERDNS=yes
TYPE=Ethernet 

- If you have a static IP address, enter static in the BOOTPROTO= field. Type IPADDR= followed by the IP address (in dotted decimal notation) and type NETMASK= followed by the subnet mask. The following example shows an example where the static IP address is 192.168.1.10 and the subnet mask is 255.255.255.0.

Figure 213 Red Hat 9.0: Static IP Address Setting in ifconfig-eth0

DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.10
NETMASK=255.255.255.0
USERCTL=no
PEERDNS=yes
TYPE=Ethernet 

2 If you know your DNS server IP address(es), enter the DNS server information in the resolv.conf file in the /etc directory. The following figure shows an example where two DNS server IP addresses are specified.

Figure 214 Red Hat 9.0: DNS Settings in resolv.conf

nameserver 172.23.5.1
nameserver 172.23.5.2 

3 After you edit and save the configuration files, you must restart the network card. Enter./network restart in the /etc/rc.d/init.d directory. The following figure shows an example.

Importing Certificates

This appendix shows you how to import public key certificates into your web browser.

Public key certificates are used by web browsers to ensure that a secure web site is legitimate. When a certificate authority such as VeriSign, Comodo, or Network Solutions, to name a few, receives a certificate request from a website operator, they confirm that the web domain and contact information in the request match those on public record with a domain name registrar. If they match, then the certificate is issued to the website operator, who then places it on the site to be issued to all visiting web browsers to let them know that the site is legitimate.

Many ZyXEL products, such as the NSA-2401, issue their own public key certificates. These can be used by web browsers on a LAN or WAN to verify that they are in fact connecting to the legitimate device and not one masquerading as it. However, because the certificates were not issued by one of the several organizations officially recognized by the most common web browsers, you will need to import the ZyXEL-created certificate into your web browser and flag that certificate as a trusted authority.

Note: You can see if you are browsing on a secure website if the URL in your web browser's address bar begins with https:// or there is a sealed padlock icon ( ) somewhere in the main browser window (not all browsers show the padlock in the same location.)

In this appendix, you can import a public key certificate for:

• Internet Explorer on page 400
• Firefox on page 410
• Opera on page 416
  • Konqueror on page 424

Internet Explorer

The following example uses Microsoft Internet Explorer 7 on Windows XP Professional; however, they can also apply to Internet Explorer on Windows Vista.

1 If your device's Web Configurator is set to use SSL certification, then the first time you browse to it you are presented with a certification error.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts

as the successor of the GNU Library Public License, version 2, hence the version number 2.1.

Preamble

The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users.

This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below.

When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get

it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things.

To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it.

For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights.

We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library.

To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others.

Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the

users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license.

Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs.

When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library.

We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances.

For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system.

Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library.

The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run.

GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

1. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License").

Each licensee is addressed as "you".

A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".)

"Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does.

1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied

by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote

it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

1. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library.

2. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not

compelled to copy the source along with the object code.

1. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License.

However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself.

1. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding

machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a

copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.

It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute.

1. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work.

2. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

3. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its

terms and conditions for copying, distributing or modifying the Library or works based on it.

1. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License.

2. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to

refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

1. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.

2. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later

version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation.

1. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing

and reuse of software generally.

NO WARRANTY

1. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

2. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCHDAMAGES.

Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate

to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and modification follow.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

1. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.

2. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

3. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:

a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.

b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.

c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

1. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,

b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code,

to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the

scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.

1. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

2. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.

3. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.

4. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this

License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

1. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.

2. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.

3. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.

NO WARRANTY

1. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

1. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

GNU LESSER GENERAL PUBLIC LICENSE

Version 3, 29 June 2007

Copyright (C) 2007 Free Software Foundation, Inc. http://fsf.org/

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below.

1. Additional Definitions.

As used herein, “this License” refers to version 3 of the GNU Lesser General Public License, and the “GNU GPL” refers to version 3 of the GNU General Public License.

"The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below.

An “Application” is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library.

A “Combined Work” is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the “Linked Version”.

The “Minimal Corresponding Source” for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version.

The “Corresponding Application Code” for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work.

1. Exception to Section 3 of the GNU GPL.

You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL.

1. Conveying Modified Versions.

If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version:

- a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or

- b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy.

1. Object Code Incorporating Material from Library Header Files.

The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following:

• a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License.

• b) Accompany the object code with a copy of the GNU GPL and this license document.

• Combined Works.

You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following:

- a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License.

- b) Accompany the Combined Work with a copy of the GNU GPL and this license document.

•c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document.

•d) Do one of the following:

o0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.

o1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version.

- e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.)

5. Combined Libraries.

You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following:

- a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License.

- b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work.

1. Revised Versions of the GNU Lesser General Public License.

The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation.

If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library.

GNU GENERAL PUBLIC LICENSE

Version 3, 29 June 2007

Copyright (C) 2007 Free Software Foundation, Inc. http://fsf.org/

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

Preamble

The GNU General Public License is a free, copyleft license for software and other kinds of works.

The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.

To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these

terms so they know their rights.

Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.

For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.

Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most

unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.

Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free.

The precise terms and conditions for copying, distribution and modification follow.

TERMS AND CONDITIONS

0. Definitions.

"This License" refers to version 3 of the GNU General Public License.

“Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.

“The Program” refers to any copyrightable work licensed under this License. Each licensee is addressed as “you”. “Licensees” and “recipients” may be individuals or organizations.

To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a “modified version” of the earlier work or a work “based on” the earlier work.

A “covered work” means either the unmodified Program or a work based on the Program.

To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.

An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.

1. Source Code.

The “source code” for a work means the preferred form of the work for making modifications to it. “Object code” means any non-source form of a work.

A “Standard Interface” means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.

The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A “Major Component”, in this context, means a major essential component (kernel, window system, and so on)

of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.

The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.

The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.

The Corresponding Source for a work in source code form is that same work.

1. Basic Permissions.

All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.

You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.

Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.

1. Protecting Users' Legal Rights From Anti-Circumvention Law.

No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.

When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.

1. Conveying Verbatim Copies.

You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.

You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.

1. Conveying Modified Source Versions.

You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:

- a) The work must carry prominent notices stating that you modified it, and giving a relevant date.

• b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to “keep intact all notices”.
  •c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
• d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.

A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.

1. Conveying Non-Source Forms.

You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:

• a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
• b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
  •c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
• d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.

- e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.

A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.

A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, “normally used” refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.

“Installation Information” for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.

If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).

The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.

Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.

1. Additional Terms.

“Additional permissions” are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.

When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.

Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:

- a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or

- b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or

•c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
- d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
- e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
- f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.

All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.

If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.

Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.

1. Termination.

You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).

However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.

Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.

Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.

1. Acceptance Not Required for Having Copies.

You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.

1. Automatic Licensing of Downstream Recipients.

Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.

An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or

could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.

You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.

1. Patents.

A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's “contributor version”.

A contributor's “essential patent claims” are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, “control” includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.

Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a “patent license” is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To “grant” such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.

If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. “Knowingly relying” means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.

If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.

A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.

Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.

1. No Surrender of Others' Freedom.

If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.

1. Use with the GNU Affero General Public License.

Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License.

The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.

1. Disclaimer of Warranty.

THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

1. Limitation of Liability.

IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

1. Interpretation of Sections 15 and 16.

If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.

This Product includes rsync 3.0.0 software under GPL 3.0 license

GNU GENERAL PUBLIC LICENSE

Version 3, 29 June 2007

Copyright © 2007 Free Software Foundation, Inc. http://fsf.org/

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

Preamble

The GNU General Public License is a free, copyleft license for software and other kinds of works.

The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.

To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.

For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.

Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.

Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free.

The precise terms and conditions for copying, distribution and modification follow.

TERMS AND CONDITIONS

0. Definitions.

"This License" refers to version 3 of the GNU General Public License.

"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.

"The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations.

To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a “modified version” of the earlier work or a work “based on” the earlier work.

A “covered work” means either the unmodified Program or a work based on the Program.

To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.

To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.

An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.

1. Source Code.

The “source code” for a work means the preferred form of the work for making modifications to it. “Object code” means any non-source form of a work.

A “Standard Interface” means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.

The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A “Major Component”, in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.

The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.

The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.

The Corresponding Source for a work in source code form is that same work.

2. Basic Permissions.

All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.

You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.

Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.

3. Protecting Users' Legal Rights From Anti-Circumvention Law.

No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.

When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.

4. Conveying Verbatim Copies.

You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.

You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.

5. Conveying Modified Source Versions.

You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:

• a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
• b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to “keep intact all notices”.
  •c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
• d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.

A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.

6. Conveying Non-Source Forms.

You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:

• a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
• b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.

•c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
- d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
- e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.

A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.

A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, “normally used” refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.

"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.

If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply

if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).

The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.

Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.

7. Additional Terms.

"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.

When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.

Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:

• a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
• b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
  •c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or

• d) Limiting the use for publicity purposes of names of licensors or authors of the material; or

• e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or

• f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.

All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.

If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.

Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.

8. Termination.

You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).

However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.

Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.

Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.

9. Acceptance Not Required for Having Copies.

You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.

10. Automatic Licensing of Downstream Recipients.

Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.

An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.

You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.

11. Patents.

A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's “contributor version”.

A contributor's “essential patent claims” are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, “control” includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.

Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.

In the following three paragraphs, a “patent license” is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To “grant” such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.

If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. “Knowingly relying” means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.

If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.

A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.

Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.

12. No Surrender of Others' Freedom.

If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.

13. Use with the GNU Affero General Public License.

Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.

14. Revised Versions of this License.

The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.

If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.

Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.

15. Disclaimer of Warranty.

THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE

COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

16. Limitation of Liability.

IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

17. Interpretation of Sections 15 and 16.

If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.

To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the “copyright” line and a pointer to where the full notice is found.

Copyright (C)

This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.

You should have received a copy of the GNU General Public License along with this program. If not, see http://www.gnu.org/licenses/.

Also add information on how to contact you by electronic and paper mail.

If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode:

Copyright (C)

This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

This is free software, and you are welcome to redistribute it

under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box".

You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see http://www.gnu.org/licenses/.

The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it

more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read http://www.gnu.org/philosophy/why-not-lgpl.html.

Version 1.2, November 2002

Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.

51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

0. PREAMBLE

The purpose of this License is to make a manual, textbook, or other functional and useful document "free" in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way

to get credit for their work, while not being considered responsible for modifications made by others. This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.

We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.

1. APPLICABILITY AND DEFINITIONS

This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law.

A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with

modifications and/or translated into another language. A "Secondary Section" is a named appendix or a front-matter section of

the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.

The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none. The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may

be at most 5 words, and a Back-Cover Text may be at most 25 words.

A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of

pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text or matters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been

arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque".

Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary ormats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.

The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text. A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition.

The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.

2. VERBATIM COPYING

You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept

compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.

You may also lend copies, under the same conditions stated above, and you may publicly display copies.

3. COPYING IN QUANTITY

If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.

If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.

If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.

It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.

4. MODIFICATIONS

You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:

A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions

(which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission.

B. List on the Title Page, as authors, one or more persons or entities

responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the

Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement.

C. State on the Title page the name of the publisher of the Modified Version, as the publisher.

D. Preserve all the copyright notices of the Document.

E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices.

F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below.

G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice.

H. Include an unaltered copy of this License.

I. Preserve the section Entitled "History", Preserve its Title, and add to it an item stating at least the title, year, new authors, and

publisher of the Modified Version as given on the Title Page. If there is no section Entitled "History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence.

J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the "History" section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission.

K. For any section Entitled "Acknowledgements" or "Dedications", Preserve the Title of the section, and preserve in the section all

the substance and tone of each of the contributor acknowledgements and/or dedications given therein.

L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers

or the equivalent are not considered part of the section titles.

M. Delete any section Entitled "Endorsements". Such a section may not be included in the Modified Version.

N. Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title with any Invariant Section.

O. Preserve any Warranty Disclaimers.

If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material

copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles.

You may add a section Entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.

You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.

The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.

5. COMBINING DOCUMENTS

You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers.

The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work.

In the combination, you must combine any sections Entitled "History" in the various original documents, forming one section Entitled "History"; likewise combine any sections Entitled "Acknowledgements", and any sections Entitled "Dedications". You must delete all sections Entitled "Endorsements".

6. COLLECTIONS OF DOCUMENTS

You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.

You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.

7. AGGREGATION WITH INDEPENDENT WORKS

A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an "aggregate" if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document.

If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the

electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate.

8. TRANSLATION

Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4.

Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include

translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a

translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.

If a section in the Document is Entitled "Acknowledgements", "Dedications", or "History", the requirement (section 4) to Preserve

its Title (section 1) will typically require changing the actual title.

9. TERMINATION

You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this License. Any other attempt to copy, modify, sublicense or distribute the Document is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

10. FUTURE REVISIONS OF THIS LICENSE

The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in

spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/.

Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation.

ADDENDUM: How to use this License for your documents

To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page:

Copyright (c) YEAR YOUR NAME.

Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.2 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled "GNU

Free Documentation License".

If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the "with...Texts." line with this:

with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.

If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the

situation. If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.

1. Distribution Obligations.

3.1. Application of License.

The Modifications which You create or to which You contribute are governed by the terms of this License, including without limitation Section 2.2. The Source Code version of Covered Code may be distributed only under the terms of this License or a future version of this License released under Section 6.1, and You must include a copy of this License with every copy of the Source Code You distribute. You may not offer or impose any terms on any Source Code version that alters or restricts the applicable version of this License or the recipients' rights hereunder. However, You may include an additional document offering the additional rights described in Section 3.5.

3.2. Availability of Source Code.

Any Modification which You create or to which You contribute must be made available in Source Code form under the terms of this License either on the same media as an Executable version or via an accepted Electronic Distribution Mechanism to anyone to whom you made an Executable version available; and if made available via Electronic Distribution Mechanism, must remain available for at least twelve (12) months after the date it initially became available, or at least six (6) months after a subsequent version of that particular Modification has been made available to such recipients. You are responsible for ensuring that the Source Code version remains available even if the Electronic Distribution Mechanism is maintained by a third party.

3.3. Description of Modifications.

You must cause all Covered Code to which You contribute to contain a file documenting the changes You made to create that Covered Code and the date of any change. You must include a prominent statement that the Modification is derived, directly or indirectly, from Original Code provided by the Initial Developer and including the name of the Initial Developer in (a) the Source Code, and (b) in any notice in an Executable version or related documentation in which You describe the origin or ownership of the Covered Code.

3.4. Intellectual Property Matters

(a) Third Party Claims.

If Contributor has knowledge that a license under a third party's intellectual property rights is required to exercise the rights granted by such Contributor under Sections 2.1 or 2.2, Contributor must include a text file with the Source Code distribution titled "LEGAL" which describes the claim and the party making the claim in sufficient detail that a recipient will know whom to contact. If Contributor obtains such knowledge after the Modification is made available as described in Section 3.2, Contributor shall promptly modify the LEGAL file in all copies Contributor makes available thereafter and shall take other steps (such as notifying appropriate mailing lists or newsgroups) reasonably calculated to inform those who received the Covered

Code that new knowledge has been obtained.

(b) Contributor APIs.

If Contributor's Modifications include an application programming interface and Contributor has knowledge of patent licenses which are reasonably necessary to implement that API, Contributor must also include this information in the LEGAL file.

(c) Representations.

Contributor represents that, except as disclosed pursuant to Section 3.4(a) above, Contributor believes that Contributor's Modifications are Contributor's original creation(s) and/or Contributor has sufficient rights to grant the rights conveyed by this License.

3.5. Required Notices.

You must duplicate the notice in Exhibit A in each file of the Source Code. If it is not possible to put such notice in a particular Source Code file due to its structure, then You must include such notice in a location (such as a relevant directory) where a user would be likely to look for such a notice. If You created one or more Modification(s) You may add your name as a Contributor to the notice described in Exhibit A. You must also duplicate this License in any documentation for the Source Code where You describe recipients' rights or ownership rights relating to Covered Code. You may choose to offer, and to

charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Code. However, You may do so only on Your own behalf, and not on behalf of the Initial Developer or any Contributor. You must make it absolutely clear than any such warranty, support, indemnity or liability obligation is offered by You alone, and You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of warranty, support, indemnity or liability terms You offer.

3.6. Distribution of Executable Versions.

You may distribute Covered Code in Executable form only if the requirements of Section 3.1-3.5 have been met for that Covered Code, and if You include a notice stating that the Source Code version of the Covered Code is available under the terms of this License, including a description of how and where You have fulfilled the obligations of Section 3.2. The notice must be conspicuously included in any notice in an Executable version, related documentation or collateral in which You describe recipients' rights relating to the Covered Code. You may distribute the Executable version of Covered Code or ownership rights under a license of Your choice, which may contain terms different from this License, provided that You are in compliance with the terms of this License and that the license for the Executable version does not attempt to limit or alter the recipient's rights in the Source Code version from the rights set forth in this

License. If You distribute the Executable version under a different license You must make it absolutely clear that any terms which differ from this License are offered by You alone, not by the Initial Developer or any Contributor. You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of any such terms You offer.

3.7. Larger Works.

You may create a Larger Work by combining Covered Code with other code not governed by the terms of this License and distribute the Larger Work as a single product. In such a case, You must make sure the requirements of this License are fulfilled for the Covered Code.

4. Inability to Comply Due to Statute or Regulation.

If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Code due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be included in the LEGAL file described in Section 3.4 and must be included with all distributions of the Source Code. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to

understand it.

1. Application of this License.

This License applies to code to which the Initial Developer has attached the notice in Exhibit A and to related Covered Code.

1. Versions of the License.

6.1. New Versions.

Netscape Communications Corporation ("Netscape") may publish revised and/or new versions of the License from time to time. Each version will be given a distinguishing version number.

6.2. Effect of New Versions.

Once Covered Code has been published under a particular version of the License, You may always continue to use it under the terms of that version. You may also choose to use such Covered Code under the terms of any subsequent version of the License published by Netscape. No one other than Netscape has the right to modify the terms applicable to Covered Code created under this License.

6.3. Derivative Works.

If You create or use a modified version of this License (which you may only do in order to apply it to code which is not already Covered Code

governed by this License), You must (a) rename Your license so that the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",

"MPL", "NPL" or any confusingly similar phrase do not appear in your license (except to note that your license differs from this License)

and (b) otherwise make it clear that Your version of the license contains terms which differ from the Mozilla Public License and

Netscape Public License. (Filling in the name of the Initial

Developer, Original Code or Contributor in the notice described in

Exhibit A shall not of themselves be deemed to be modifications of this License.)

7. DISCLAIMER OF WARRANTY.

COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,

WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,

WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF

DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGEMENT.

THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE

IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,

YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE

COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER

OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF

ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.

8. TERMINATION.

8.1. This License and the rights granted hereunder will terminate automatically if You fail to comply with terms herein and fail to cure such breach within 30 days of becoming aware of the breach. All sublicenses to the Covered Code which are properly granted shall survive any termination of this License. Provisions which, by their nature, must remain in effect beyond the termination of this License shall survive.

8.2. If You initiate litigation by asserting a patent infringement claim (excluding declaratory judgment actions) against Initial Developer or a Contributor (the Initial Developer or Contributor against whom You file such action is referred to as "Participant") alleging that:

(a) such Participant's Contributor Version directly or indirectly infringes any patent, then any and all rights granted by such Participant to You under Sections 2.1 and/or 2.2 of this License shall, upon 60 days notice from Participant terminate prospectively, unless if within 60 days after receipt of notice You either: (i) agree in writing to pay Participant a mutually agreeable reasonable

royalty for Your past and future use of Modifications made by such Participant, or (ii) withdraw Your litigation claim with respect to the Contributor Version against such Participant. If within 60 days of notice, a reasonable royalty and payment arrangement are not mutually agreed upon in writing by the parties or the litigation claim is not withdrawn, the rights granted by Participant to You under Sections 2.1 and/or 2.2 automatically terminate at the expiration of the 60 day notice period specified above.

(b) any software, hardware, or device, other than such Participant's Contributor Version, directly or indirectly infringes any patent, then any rights granted to You by such Participant under Sections 2.1(b) and 2.2(b) are revoked effective as of the date You first made, used, sold, distributed, or had made, Modifications made by that Participant.

8.3. If You assert a patent infringement claim against Participant alleging that such Participant's Contributor Version directly or indirectly infringes any patent where such claim is resolved (such as by license or settlement) prior to the initiation of patent infringement litigation, then the reasonable value of the licenses granted by such Participant under Sections 2.1 or 2.2 shall be taken into account in determining the amount or value of any payment or license.

8.4. In the event of termination under Sections 8.1 or 8.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or any distributor hereunder prior to termination shall survive termination.

9. LIMITATION OF LIABILITY.

UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL

DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,

OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR

ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY

CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,

WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER

COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN

INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF

LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY

RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW

PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE

EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO

THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.

1. U.S. GOVERNMENT END USERS.

The Covered Code is a "commercial item," as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer software" and "commercial computer software documentation," as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government End Users acquire Covered Code with only those rights set forth herein.

1. MISCELLANEOUS.

This License represents the complete agreement concerning subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. This License shall be governed by California law provisions (except to the extent applicable law, if any, provides otherwise), excluding its conflict-of-law provisions. With respect to disputes in which at least one party is a citizen of, or an entity chartered or registered to do business in the United States of America, any litigation relating to this License shall be subject to the jurisdiction of the Federal Courts of the Northern District of California, with venue lying in Santa Clara County, California, with the losing party responsible for costs, including without limitation, court costs and reasonable attorneys' fees and

expenses. The application of the United Nations Convention on Contracts for the International Sale of Goods is expressly excluded. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not apply to this License.

12. RESPONSIBILITY FOR CLAIMS.

As between Initial Developer and the Contributors, each party is responsible for claims and damages arising, directly or indirectly, out of its utilization of rights under this License and You agree to work with Initial Developer and Contributors to distribute such responsibility on an equitable basis. Nothing herein is intended or shall be deemed to constitute any admission of liability.

13. MULTIPLE-LICENSED CODE.

Initial Developer may designate portions of the Covered Code as "Multiple-Licensed".

INTRODUCTION

The Boost Software License specifies the terms and conditions of use for those Boost libraries that it covers.

Currently, some Boost libraries have their own licenses. The hope is that eventually all Boost libraries will be covered by the Boost Software License. In the meantime, all libraries comply with the Boost License requirements.

HISTORY

As Boost grew, it became unmanageable for each Boost file to have its own license. Users complained that each license needed to be reviewed, and that reviews were difficult or impossible if Boost libraries contained many different licenses. Boost moderators and maintainers spent excessive time dealing with license issues. Boost developers often copied existing licenses without actually knowing if the license wording met legal needs.

To clarify these licensing issues, the Boost moderators asked for help from the Berkman Center for Internet & Society at Harvard Law School, Cambridge, Massachusetts, USA. It was requested that a single Boost license be developed that met the traditional requirements that Boost licenses, particularly:

oMust be simple to read and understand.

oMust grant permission without fee to copy, use and modify the software for any use (commercial and non-commercial).

oMust require that the license appear with all copies [including redistributions] of the software source code.

oMust not require that the license appear with executables or other binary uses of the library.

oMust not require that the source code be available for execution or other binary uses of the library.

Additionally, other common open source licenses were studied to see what additional issues were being treated, and additions representing good legal practice were also requested. The result is the Boost Software License:

Boost Software License - Version 1.0 - August 17th, 2003

Permission is hereby granted, free of charge, to any person or organization obtaining a copy of the software and accompanying documentation covered by this license (the "Software") to use, reproduce, display, distribute, execute, and transmit the Software, and to prepare derivative works of the Software, and to permit third-parties to whom the Software is furnished to do so, all subject to the following:

The copyright notices in the Software and this entire statement, including the above license grant, this restriction and the following disclaimer, must be included in all copies of the Software, in whole or in part, and all derivative works of the Software, unless such copies or derivative works are solely in the form of machine-executable object code generated by a source language processor.

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR

IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,

FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON-INFRINGEMENT. IN NO EVENT

SHALL THE COPYRIGHT HOLDERS OR ANYONE DISTRIBUTING THE SOFTWARE BE LIABLE

FOR ANY DAMAGES OR OTHER LIABILITY, WHETHER IN CONTRACT, TORT OR OTHERWISE,

ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER

DEALINGS IN THE SOFTWARE.

RATIONALE

The following rationale was provided by Devin Smith, the lawyer who wrote the Boost Software License. It has been edited slightly for brevity. Editorial additions are shown in square brackets.

Benefit of Common Software License

If one of Boost's goals is to ease use and adoption of the various libraries made available by Boost, it does make sense to try to standardize the licenses under

which the libraries are made available to users. (I make some recommendations about a possible short-form license below.)

[Standardizing the license will not] necessarily address the issue of satisfying corporate licensees. Each corporation will have its own concerns, based on their own experiences with software licensing and distribution and, if they're careful, will want to carefully review each license, even if they've been told that they're all standard. I would expect that, unless we're remarkably brilliant (or lucky) in drafting the standard Boost license, the standard license won't satisfy the legal departments of all corporations. I imagine that some will, for instance, absolutely insist that licensors provide a warranty of title and provide indemnification for third-party intellectual property infringement claims. Others may want functional warranties. (If I were advising the corporations, I would point out that they're not paying anything for the code and getting such warranties from individual programmers, who probably do not have deep pockets, is not that valuable anyway, but other lawyers may disagree.)

But this can be addressed, not by trying to craft the perfect standard license, but by informing the corporations that they can, if they don't like the standard license, approach the authors to negotiate a different, perhaps even paid, license.

One other benefit of adopting a standard license is to help ensure that the license accomplishes, from a legal perspective, what the authors intend. For instance, many of the [original] licenses for the libraries available on boost.org do not disclaim the warranty of title, meaning that the authors could, arguably, be sued by a user if the code infringes the rights of a third party and the user is sued by that third party. I think the authors probably want to disclaim this kind of liability.

Short-Form License

Without in anyway detracting from the draft license that's been circulated [to Boost moderators], I'd like to propose an alternative "short-form" license that Boost could have the library authors adopt. David [Abrahams] has expressed a desire to keep things as simple as possible, and to try to move away from past practice as little as possible, and this is my attempt at a draft.

This license, which is very similar to the BSD license and the MIT license, should satisfy the Open Source Initiative's Open Source Definition: (i) the license permits free redistribution, (ii) the distributed code includes source code, (iii) the license permits the creation of derivative works, (iv) the license does not discriminate against persons or groups, (v) the license does not discriminate against fields of endeavor, (vi) the rights apply to all to whom the program is redistributed, (vii) the license is not specific to a product, and (viii) the license is technologically neutral (i.e., it does not [require] an explicit gesture of assent in order to establish a contract between licensor and licensee).

This license grants all rights under the owner's copyrights (as well as an implied patent license), disclaims all liability for use of the code (including intellectual property infringement liability), and requires that all subsequent copies of the code [except machine-executable object code], including partial copies and derivative works, include the license.

FAQ

How should Boost programmers apply the license to source and header files? Add a comment based on the following template, substituting appropriate text for the italicized portion:

// Copyright Joe Coder 2004 - 2006.

// Distributed under the Boost Software License, Version 1.0.

// (See accompanying file LICENSE_1_0.txt or copy at

// http://www.boost.org/LICENSE_1_0.txt)

Please leave an empty line before and after the above comment block. It is fine if the copyright and license messages are not on different lines; in no case there should be other intervening text. Do not include "All rights reserved" anywhere.

Other ways of licensing source files have been considered, but some of them turned out to unintentionally nullify legal elements of the license. Having fixed language for referring to the license helps corporate legal departments evaluate the boost distribution. Creativity in license reference language is strongly discouraged, but judicious changes in the use of whitespace are fine.

How should the license be applied to documentation files, instead? Very similarly to the way it is applied to source files: the user should see the very same text indicated in the template above, with the only difference that both the local and the web copy of LICENSE_1_0.txt should be linked to. Refer to the HTML source code of this page in case of doubt.

Note that the location of the local LICENSE_1_0.txt needs to be indicated relatively to the position of your documentation file (../LICENSE_1_0.txt, .././LICENSE_1_0.txt etc.)

How is the Boost license different from the GNU General Public License (GPL)? The Boost license permits the creation of derivative works for commercial or non-commercial use with no legal requirement to release your source code. Other differences include Boost not requiring reproduction of copyright messages for object code redistribution, and the fact that the Boost license is not "viral": if you distribute your own code along with some Boost code, the Boost license applies only to the Boost code (and modified versions thereof); you are free to license your own code under any terms you like. The GPL is also much longer, and thus may be harder to understand.

Why the phrase "machine-executable object code generated by a source language processor"? To distinguish cases where we do not require reproduction of the copyrights and license, such as object libraries, shared libraries, and final program executables, from cases where reproduction is still required, such as distribution of self-extracting archives of source code or precompiled header files. More detailed wording was rejected as not being legally necessary, and reducing readability.

Why is the "disclaimer" paragraph of the license entirely in uppercase? Capitalization of these particular provisions is a US legal mandate for consumer protection. (Diane Cabell)

Does the copyright and license cover interfaces too? The conceptual interface to a library isn't covered. The particular represen-

tation expressed in the header is covered, as is the documentation, examples, test programs, and all the other material that goes with the library. A different implementation is free to use the same logical interface, however. Interface issues have been fought out in court several times; ask a lawyer for details.

Why doesn't the license prohibit the copyright holder from patenting the covered software? No one who distributes their code under the terms of this license could turn around and sue a user for patent infringement. (Devin Smith)

Boost's lawyers were well aware of patent provisions in licenses like the GPL and CPL, and would have included such provisions in the Boost license if they were believed to be legally useful.

Why doesn't the copyright message say "All rights reserved"? Devin Smith says "I don't think it belongs in the copyright notice for anything (software, electronic documentation, etc.) that is being licensed. It belongs in books that are sold where, in fact, all rights (e.g., to reproduce the book, etc.) are being reserved in the publisher or author. I think it shouldn't be in the BSD license."

Do I have to copyright/license trivial files? Even a test file that just contains an empty main() should have a copyright. Files without copyrights make corporate lawyers nervous, and that's a barrier to adoption. The more of Boost is uniformly copyrighted and licensed the low problem people will have with printing a Boost universe CD on a corporate series

TRANSITION

To ease the transition of the code base towards the new common license, several people decided to give a blanket permission for all their contributions to use the new license. This hopefully helps maintainers to switch to the new license once the list contains enough names without asking over and over again for each change. Please consider adding your name to the list.

License Issues

Curl and libcurl are released under a MIT/X derivate license. The license is very liberal and should not impose a problem for your project. This section is just a brief summary for the cases we get the most questions. (Parts of this section was much enhanced by Bjorn Reese.)

We are not lawyers and this is not legal advice. You should probably consult one if you want true and accurate legal insights without our prejudice.

6.1 I have a GPL program, can I use the libcurl library?

Yes!

Since libcurl may be distributed under the MIT/X derivate license, it can be used together with GPL in any software.

6.2 I have a closed-source program, can I use the libcurl library?

Yes!

libcurl does not put any restrictions on the program that uses the library.

6.3 I have a BSD licensed program, can I use the libcurl library?

Yes!

libcurl does not put any restrictions on the program that uses the library.

6.4 I have a program that uses LGPL libraries, can I use libcurl?

Yes!

The LGPL license doesn't clash with other licenses.

6.5 Can I modify curl/libcurl for my program and keep the changes secret?

Yes!

The MIT/X derivate license practically allows you to do almost anything with the sources, on the condition that the copyright texts in the sources are left intact.

6.6 Can you please change the curl/libcurl license to XXXX?

No.

We have carefully picked this license after years of development and

discussions and a large amount of people have contributed with source code knowing that this is the license we use. This license puts the restrictions we want on curl/libcurl and it does not spread to other programs or libraries that use it. It should be possible for everyone to use libcurl or curl in their projects, no matter what license they already have in use.

6.7 What are my obligations when using libcurl in my commercial apps?

Next to none. All you need to adhere to is the MIT-style license (stated in the COPYING file) which basically says you have to include the copyright notice in "all copies" and that you may not use the copyright holder's name when promoting your software.

You do not have to release any of your source code.

You do not have to reveal or make public any changes to the libcurl source code.

You do not have to reveal or make public that you are using libcurl within your app.

As can be seen here: http://curl.haxx.se/docs/companies.html and elsewhere, more and more companies are discovering the power of libcurl and take advantage of it even in commercial environments.

SQLite Copyright

All of the deliverable code in SQLite has been dedicated to the public domain by the authors. All code authors, and representatives of the companies they work for, have signed affidavits dedicating their contributions to the public domain and originals of those signed affidavits are stored in a firesafe at the main offices of Hwaci. Anyone is free to copy, modify, publish, use, compile, sell, or distribute the original SQLite code, either in source code form or as a compiled binary, for any purpose, commercial or non-commercial, and by any means.

The previous paragraph applies to the deliverable code in SQLite - those parts of the SQLite library that you actually bundle and ship with a larger application. Portions of the documentation and some code used as part of the build process might fall under other licenses. The details here are unclear. We do not worry about the licensing of the documentation and build code so much because none of these things are part of the core deliverable SQLite library.

All of the deliverable code in SQLite has been written from scratch. No code has been taken from other projects or from the open internet. Every line of code can be traced back to its original author, and all of those authors have public domain dedications on file. So the SQLite code base is clean and is uncontaminated with licensed code from other projects.

Obtaining An Explicit License To Use SQLite

Even though SQLite is in the public domain and does not require a license, some users want to obtain a license anyway. Some reasons for obtaining a license include:

• You are using SQLite in a jurisdiction that does not recognize the public domain.
• You are using SQLite in a jurisdiction that does not recognize the right of an author to dedicate their work to the public domain.
• You want to hold a tangible legal document as evidence that you have the legal right to use and distribute SQLite.
• Your legal department tells you that you have to purchase a license.

If you feel like you really have to purchase a license for SQLite, Hwaci, the company that employs the architect and principal developers of SQLite, will sell you one.

Contributed Code

In order to keep SQLite completely free and unencumbered by copyright, all new contributors to the SQLite code base are asked to dedicate their contributions to the public domain. If you want to send a patch or enhancement for possible inclusion in the SQLite source tree, please accompany the patch with the following statement:

Copyright Release for

Contributions To SQLite

SQLite is software that implements an embeddable SQL database engine. SQLite is available for free download from http://www.sqlite.org/. The principal author and maintainer of SQLite has disclaimed all copyright interest in his contributions to SQLite and thus released his contributions into the public domain. In order to keep the SQLite software unencumbered by copyright claims, the principal author asks others who may from time to time contribute changes and enhancements to likewise disclaim their own individual copyright interest.

Because the SQLite software found at http://www.sqlite.org/ is in the public domain, anyone is free to download the SQLite software from that website, make changes to the software, use, distribute, or sell the modified software, under either the original name or under some new name, without any need to obtain permission, pay royalties, acknowledge the original source of the software, or in any other way compensate, identify, or notify the original authors. Nobody is in any way compelled to contribute their SQLite changes and enhancements back to the SQLite website. This document concerns only changes and enhancements to SQLite that are intentionally and deliberately contributed back to the SQLite website.

For the purposes of this document, "SQLite software" shall mean any computer source code, documentation, makefiles, test scripts, or other information that is published on the SQLite website, http://www.sqlite.org/. Precompiled binaries are excluded from the definition of "SQLite software" in this document because the process of compiling the software may introduce information from outside sources which is not properly a part of SQLite.

The header comments on the SQLite source files exhort the reader to share freely and to never take more than one gives. In the spirit of that exhortation I make the following declarations:

1. I dedicate to the public domain any and all copyright interest in the SQLite software that was publicly available on the SQLite website (http://www.sqlite.org/) prior to the date of the signature below and any changes or enhancements to the SQLite software that I may cause to be published on that website in the future. I make this dedication for the benefit of the public at large and to the detriment of my heirs and successors. I intend this dedication to be an overt act of relinquishment in perpetuity of all present and future rights to the SQLite software under copyright law.
2. To the best of my knowledge and belief, the changes and enhancements that I have contributed to SQLite are either originally written by me or are derived from prior works which I have verified are also in the public domain and are not subject to claims of copyright by other parties.
3. To the best of my knowledge and belief, no individual, business, organization, government, or other entity has any copyright interest in the SQLite software as it existed on the SQLite website as of the date on the signature line below.
4. I agree never to publish any additional information to the SQLite website (by CVS, email, scp, FTP, or any other means) unless that information is an original work of authorship by me or is derived from prior published versions of SQLite. I agree never to copy and paste code into the SQLite code base from other sources. I agree never to publish on the SQLite website any information that would violate a law or breach a contract.

This Product includes crypto++ 5.5.2 software under below license

License

The License of Crypto++ is somewhat unusual amongst open source projects. A distinction is made between the library as a compilation (i.e., collection), which is copyrighted by Wei Dai, and the individual files in it, which are public domain (with the exception of mars.cpp which is subject to its own license, included in that file).

The library is copyrighted as a compilation in order to place certain disclaimers (regarding warranty, export, and patents) in the license and to keep the attributions and public domain declarations intact when Crypto++ is distributed in source code form. The fact that individual files are public domain means that legally you can place code segments, entire files, or small sets of files (up to the limit set by fair use) into your own project and do anything you want with them without worrying about the copyright.

Because one purpose of the project is to act as a repository of public domain (not copyrighted) cryptographic source code, the code in Crypto++ was either written specifically for this project by its contributors and placed in the public domain, or derived from other sources that are public domain (again with the exception of mars.cpp).

Compilation Copyright (c) 1995-2009 by Wei Dai. All rights reserved.

This copyright applies only to this software distribution package

as a compilation, and does not imply a copyright on any particular

file in the package.

The following files are copyrighted by their respective original authors,

and their use is subject to additional licenses included in these files.

mars.cpp - Copyright 1998 Brian Gladman.

All other files in this compilation are placed in the public domain by Wei Dai and other contributors.

I would like to thank the following authors for placing their works into the public domain:

Joan Daemen - 3way.cpp

Leonard Janke - cast.cpp, seal.cpp

Steve Reid - cast.cpp

Phil Karn - des.cpp

Andrew M. Kuchling - md2.cpp, md4.cpp

Colin Plumb - md5.cpp

Seal Woods - rc6.cpp

Chris Morgan - rijndael.cpp

Paulo Baretto - rijndael.cpp, skipjack.cpp, square.cpp

Richard De Moliner - safer.cpp

Matthew Skala - twofish.cpp

Kevin Springle - camellia.cpp, shacal2.cpp, ttmac.cpp, whrlpool.cpp, ripemd.cpp

Permission to use, copy, modify, and distribute this compilation for any purpose, including commercial applications, is hereby granted without fee, subject to the following restrictions:

1. Any copy or modification of this compilation in any form, except in object code form as part of an application software, must include

the above copyright notice and this license.

1. Users of this software agree that any modification or extension they provide to Wei Dai will be considered public domain and not copyrighted unless it includes an explicit copyright notice.

2. Wei Dai makes no warranty or representation that the operation of the software in this compilation will be error-free, and Wei Dai is under no obligation to provide any services, by way of maintenance, update, or otherwise. THE SOFTWARE AND ANY DOCUMENTATION ARE PROVIDED "AS IS" WITHOUT EXPRESS OR IMPLIED WARRANTY INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR

PURPOSE. IN NO EVENT WILL WEI DAI OR ANY OTHER CONTRIBUTOR BE LIABLE FOR

DIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, EVEN IF

ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

1. Users will not use Wei Dai or any other contributor's name in any publicity or advertising, without prior written consent in each case.

2. Export of this software from the United States may require a specific license from the United States Government. It is the responsibility of any person or organization contemplating export to obtain such a license before exporting.

3. Certain parts of this software may be protected by patents. It

is the users' responsibility to obtain the appropriate

licenses before using those parts.

If this compilation is used in object code form in an application

software, acknowledgement of the author is not required but would be

appreciated. The contribution of any useful modifications or extensions

to Wei Dai is not required but would also be appreciated.

This Product includes wxWidgets 2.8.9 and wxWidgets 2.9.0 software under below license

Licence

Background

wxWidgets is currently licensed under the "wxWindows Licence" pending approval of the "wxWidgets Licence" which will be identical apart from the name.

The wxWindows Licence is essentially the L-GPL (Library General Public Licence), with an exception stating that derived works in binary form may be distributed on the user's own terms. This is a solution that satisfies those who wish to produce GPL'ed soft-

dgets, and also those producing proprietary software.

Participants in the discussion that led to this decision include the folk from Abisource, Robert Roebling, Julian Smart, Markus Fleck, Karsten Ballueder, and some advice from Richard Stallman. Richard has confirmed that the new licence is compatible with GPL'ed applications. However, there are no significant restrictions on proprietary applications.

The wxWindows Licence has been approved by the Open Source Initiative, and you can find the licence on their site here.

In August 2005, an ambiguity in Clause 2 was removed (replaced "the user's" with "your") and the version bumped to 3.1.

The wxWindows Library Licence

Copyright (c) 1998 Julian Smart, Robert Roebling [, ...]

Everyone is permitted to copy and distribute verbatim copies

of this licence document, but changing it is not allowed.

EXCEPTION NOTICE

1.

2. The exception is that you may use, copy, link, modify and distribute under the user's own terms, binary object code versions of works based on the Library.

3. If you copy code from files distributed under the terms of the GNU General Public Licence or the GNU Library General Public Licence into a copy of this library, as this licence permits, the exception does not apply to the code that you add in this way. To avoid misleading anyone as to the status of such modified files, you must delete this exception notice from such code and/or adjust the licensing conditions notice accordingly.

4. If you write modifications of your own for this library, it is your choice whether to permit this exception to apply to your modifications.

If you do not wish that, you must delete the exception notice from such code and/or adjust the licensing conditions notice accordingly.

Perl5 is Copyright (C) 1993-2005, by Larry Wall and others.

It is free software; you can redistribute it and/or modify it under the terms of either:

a) the GNU General Public License as published by the Free Software Foundation; either version 1, or (at your option) any later version, or

b) the "Artistic License".

For those of you that choose to use the GNU General Public License, my interpretation of the GNU General Public License is that no Perl script falls under the terms of the GPL unless you explicitly put said script under the terms of the GPL yourself.

Furthermore, any object code linked with perl does not automatically fall under the terms of the GPL, provided such object code only adds definitions of subroutines and variables, and does not otherwise impair the resulting interpreter from executing any standard Perl script. I consider linking in C subroutines in this manner to be the moral equivalent of defining subroutines in the Perl language itself. You may sell such an object file as proprietary provided that you provide or offer to provide the Perl source, as specified by the GNU General Public License. (This is merely an alternate way of specifying input to the program.) You may also sell a binary produced by the dumping of a running Perl script that belongs to you, provided that you provide or offer to provide the Perl source as specified by the GPL. (The fact that a Perl interpreter and your code are in the same binary file is, in this case, a form of mere aggregation.)

This is my interpretation of the GPL. If you still have concerns or difficulties understanding my intent, feel free to contact me. Of course, the Artistic License spells all this out for your protection, so you may prefer to use that.
