Getting to Know Your NSA

This chapter covers the main features and applications of the NSA.

1.1 NSA Overview

The NSA (Network Storage Appliance) provides file sharing and data backup for your home network.

• Use SATA (Serial Advanced Technology Attachment) I or 3.0 Gbit/s hard disks.
• RAID (Redundant Array of Independent Disks) protects your data even if a hard disk fails.
• You can expand the NSA's storage capacity with USB devices (like hard drives).
• Use the COPY button to copy files directly to the NSA from USB devices like card readers, MP3 players, memory sticks, and digital cameras without using a computer.
• The NSA is a media server. Media clients can play the NSA's video, music and photo files. Use the included media client software to make your computers into media clients. You can also use hardware-based media clients like the DMA-1000.
• The NSA has a 10/100/1000 Mbps Ethernet port for connecting to your network.

Figure 1 Example of the NSA in a Home Network

Above is the NSA in a home network. Users back up and share data on the NSA. The DMA-1000 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 memory stick 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.

See the product specifications appendix for a more detailed list of NSA features and lists of compatible hard drives and USB devices.

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

Turn off and disconnect the NSA before you install or remove internal hard drives.

1.1.1 LEDs

The NSA LEDs (lights) tell you important information.

Figure 2 NSA Front Panel

Figure 3 NSA Rear Panel

This table describes the NSA's LEDs.

Table 1 LEDs

LED	COLOR	STATUS	DESCRIPTION
POWER	Blue	On	The NSA is turned on and receiving power.
		Off	The NSA is turned off.
HDD1/HDD2	Green	On	The hard disk drive is connected properly to the NSA.
		Blinking	The NSA is saving data to the hard disk drive.
	OrangeA	On	The NSA detected an error on the hard disk drive (like a bad sector for example). The NSA automatically tries to recover a bad sector, but the LED stays orange until the NSA restarts.
		Blinking	The hard disk drive connection came loose or the NSA detected an error on the hard disk drive (like a bad sector for example) and is saving data to the hard disk drive.
	Red	On	The hard disk drive has failed and the NSA can no longer detect it.
		Off	The NSA cannot detect a hard disk in the disk bay.
SYS	Green	On	The NSA has fully started and is operating normally.
		Blinking	The NSA is starting up.
	Red	On	The NSA has failed.
LAN	Green	On	The NSA has a successful 10/100Mbps Ethernet connection.
		Blinking	The 100M LAN is sending or receiving packets.
		Off	The NSA does not have a 10/100Mbps Ethernet connection.
	Yellow	On	The NSA has a successful 1000Mbps Ethernet connection.
		Blinking	The 1000M LAN is sending or receiving packets.
		Off	The NSA does not have a 1000Mbps Ethernet connection.
COPY	Green	On	A USB device is connected to the NSA.
		Blinking	The NSA is copying files from the USB device.
	Red	On	Copying files from the USB device failed.
		Off	No USB device is connected.

A. The HDD1 and HDD2 LEDs are dual-color (green and red). The green LED is normally on when you have a hard disk installed. If the NSA detects an error on the disk, the disk's connection comes loose, or the disk fails, the red LED also comes on. Since the green LED still stays on, the color appears to be orange. If the NSA is no longer able to detect a hard disk in the disk bay, the green LED turns off and the LED appears as red.

1.1.2 COPY Button

Use the COPY button on the front panel to copy files from a connected USB device to the NSA. The files are stored in a folder created within the public share. The name of the folder created for the copied files consists of the date and time of the copy in

year_month_day_hour Minute_second format. Up to a total of 10 GB for files can be copied. If the USB device has more than 10 GB of files, the NSA emits a long beep and does not copy any of the files.

Web Configurator Basics

This chapter describes how to access the NSA web configurator and provides an overview of its screens.

2.1 Web Configurator Overview

The web configurator is an HTML-based management interface that allows easy NSA setup and management via Internet browser. Use Internet Explorer 6.0, Mozilla Firefox 1.07, Netscape Navigator 7.0 or later versions of these browsers. The recommended screen resolution is 1024 by 768 pixels or higher.

In order to use the web configurator you need to allow:

• Web browser pop-up windows from your device. Web pop-up blocking is enabled by default in Windows XP SP (Service Pack) 2.
  JavaScript (enabled by default).

2.2 Accessing the NSA Web Configurator

Make sure your NSA is properly connected and that your computer is in the same subnet as the NSA (refer to the Quick Start Guide or the appendices).

2.2.1 Access the NSA Via NDU

If you don't know the IP address of the NSA, then use the NDU to find it. Refer to the Quick Start Guide to see how to install and run the NDU.

Figure 4 NDU Main Screen

From the NDU main page click an icon under Admin to see the web configurator screen login screen.

2.2.2 Web Browser Access

Open your browser and type in the server name of the NSA ("nsa220" is the default).

Figure 5 NSA URL

2.3 Login

The default username and password are 'admin' and '1234' respectively. Enter your username and password, then click Login. See Chapter 9 on page 85 for how to create other user accounts.

Figure 6 NSA Login Screen

You should see a screen asking you to change your password (highly recommended) as shown next. Type a new password (and retype it to confirm) and click Apply or click Ignore.

Figure 7 Change Password Screen

2.4 User-level Screens Overview

All users (including the administrator) first see the user-level access My NSA screen after login.

Figure 8 My NSA

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.

The icons and language label at the top-right of the screen (1) are visible from most screens. Use the tabs at the top of the screen to navigate between the user-level screens and menus. The following table describes the 'global' icons and tabs in the user-level screens.

Table 2 User-level Global Labels and Icons

2.5 My NSA Screen

Use the My NSA screens to manage your shares and access the files in folders to which you have access.

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.

The main MyNSA screen displays the shares to which you have access.

Apply	Click this button to save your changes back to the NSA.
Cancel	Click this button to begin configuring this screen afresh.

2.5.4 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 255 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.

2.5.5 Share Paths

A share path is the full path to a folder on a volume that will be shared, for example, /mysna/topsecret/ugs/. This is independent from a "share name" which is the name shown for this share when accessing the share via CIFS or FTP. The path should start with a '/' (forward slash) followed by a parent folder, child folders leading to the folder that is to be shared.

The share path can include all characters including unicode characters (that is, you can use Chinese folder names for example) except for the following characters:

• [backslash] this will be converted to forward slash and interpreted as a path delimiter
• / [forward slash] this is always interpreted as a path delimiter, so a folder cannot include it in its folder name
  : [colon]
• [asterisk]
  ? [question mark]
• "[double quote]"
• < [less than]

• [greater than]

• | [pipe]

Please also note the following as regards share paths:

• If the share path is missing the root path slash (the first forward slash), the system will automatically add the initial slash.
• If the share path is missing the end trailing slash, the system will automatically add the trailing slash.
• If the share path has ' (backslashes) instead of ' /' (forward slashes) they will all be automatically converted to forward slashes.
• Share paths are case sensitive.
• The maximum share path length is 600 characters (the entire path string including slashes)
• The share path cannot be blank
• You cannot have an empty folder name, that is, two consecutive slashes (for example, '/ My//Corner/')
  Each individual folder in the path (that is, the content between the slashes) cannot exceed 255 characters

This chapter provides tutorials that show how to use the NSA.

3.1 Tutorials Introduction

The following tutorials cover how you use 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 Quick Start Guide for how to play media files using the included DLNA-compliant media client software. See the rest of this User's Guide for details on configuring the NSA's various screens.

3.2 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 2.3 on page 30) and click Administration to go to the configuration screens.

Figure 16 My NSA
2 Click Users to open the Users screen. Then click Create a New Account.

Figure 17 Users

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.

Figure 18 Users > Create Example

4 The account now displays in the Users screen.

Figure 19 Users (Account Created)

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 3.3 on page 44 to create shares for Jimmy and Kevin.

3.3 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 > Create a New Share.

Figure 20 Shares

2 Specify a name for the share and select which volume it should be on. Then click Browse.

Figure 21 Shares > Create Example

3 Type a name for a new folder and click Create Folder.

Figure 22 Shares > Create > Browse > Create Folder Example

4 Select the new folder and click Apply.

Figure 23 Shares > Create > Browse > New Folder Example
5 Configure the screen as follows and click Apply.

Figure 24 Shares > Create Example

Now that Bob has created Jimmy's share, he can go through the steps again to create another share for Kevin. Then he can see the rest of the tutorials for how to use the shares.

3.4 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. In this example, Bob has already installed the NDU on Jimmy's computer (see the Quick Start Guide for details). Here he maps Jimmy's share to Jimmy's computer.

1 Start Windows Explorer and click Tools > Map Network Drive.

Figure 25 NSA Top Level

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

Figure 26 Map Network Drive

3 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.

Figure 27 Enter Network Password

4 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.

Figure 28 Example Share Mapped (Folders View)

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.

3.5 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.

Figure 29 FTP Example: Typing the FTP Target
2 Enter your password and click Login.

Figure 30 FTP Example: Enter the Password

3 Now you can access files and copy files from/to your local computer's drives to or from this network folder.

1. Even though the admin share displays, user accounts cannot access it unless you change it's share access settings.

Figure 31 FTP Example: Logged In

3.6 Accessing a Share Through the Web Configurator

You can browse and access files through the web configurator.

1 Log into the NSA web configurator (see Section 2.3 on page 30) using your username and password.

Figure 32 My NSA User Login

2 Click a share to see the top level of the share's contents. Here is the Jimmy share.

Figure 33 My NSA User Login

3 Click a folder's file name to browse the folder. You can open files or copy them to your computer. However at the time of writing you cannot use the web configurator to upload files to the NSA (use CIFS or FTP to upload files, see Section 3.4 on page 46 and Section 3.5 on page 48).
4 Click the logout icon when your are done (see Table 2 on page 32).

This chapter introduces the NSA Status screen.

System Setting Screens

This chapter discusses the system setting screens.

5.1 System Setting Screens

This section gives an overview of the various features included in the system setting screens.

Use the system setting screens to:

• Specify the NSA's Windows/CIFS server name and workgroup name.
• Chose a time zone and/or allow the NSA to synchronize with a time server.
• Create and edit volumes (see Chapter 6 on page 61 for details).

5.1.1 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 and Mac OSX operating systems.
• You can use Samba with Linux to use CIFS.
• CIFS transfers use security.

5.2 Server Name

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 or domain.

CIFS cannot be disabled on the NSA.

Click System Setting > Server Name to open the following screen.

5.3 Date/Time

Use this screen to select a time zone and a time server from which your NSA can get the time and date. This time is then used in NSA logs and alerts.

5.3.1 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.

5.3.2 Date/Time Screen

Click the System Setting link in the navigation panel and then click the Date/Time link to access the System Setting > Date/Time screen.

Storage Screens

This chapter covers storage systems, volumes and disks on the NSA.

6.1 Storage Introduction

Use the Storage screens to create and manage NSA volumes (internal and external) and disks.

• See Section 6.3 on page 62 for more information on volumes.
  See Section 6.5 on page 68 for more information on disks.

6.2 Storage Overview Screen

Click Storage in the Navigation panel to display the following screen.

Figure 38 Storage

The following table describes the labels in this screen.

Table 14 Storage > Overview

LABEL	DESCRIPTION

You see a warning screen before you delete a volume.

Figure 39 Delete a Volume Warning Screen

6.3 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.

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

For example if you originally have one disk configured at 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.

Table 15 RAID Quick Comparison

RAID Level	0	1
Number of Disks	2	2
Capacity	S*N	S*N/2
Storage Efficiency	100%	50%
Fault Tolerance	None	YYYY
Availability	Y	YYYY
Read Performance	YYYY	YYYY
Write Performance	YYYY	YYYY

6.3.1 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 6.4 on page 65 for theoretical background on JBOD and the RAID levels used on the NSA. Typical applications for each method are also shown there.

6.3.1.1 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).

6.3.1.2 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. You can either add an additional disk to your one-disk JBOD volume (and you don't have to re-create shares, access rights etc.) or create a different JBOD volume (and create new shares, access rights and so on).

• 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.

6.3.2 Volume Status

You (the administrator) can see the status of a volume in the Status, Storage > Overview or Storage > Volume 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 your USB disk was formatted as NTFS. It is read-only for the NSA.
• Resync when you create or repair a RAID volume.
• 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 112 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.

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

6.3.3 Resynchronizing a RAID 1 Volume

Resynchronizing a RAID 1 volume 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.

You should not restart the NSA while the NSA is resynchronizing a volume as this will cause the synchronization to begin again after the NSA fully reboots.

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

6.4 RAID

This section contains theoretical background on JBOD and the RAID levels used on the NSA. Skip to the next section if you already understand RAID and know what storage system you want to use 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.

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.

6.4.1 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 16 JBOD

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

6.4.2 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 17 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.

6.4.3 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 18 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.

6.4.4 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 firewall and/or IDP (Intrusion Detection and Prevention) device to protect it. Preferably it should be a hardware-based firewall with stateful packet inspection, anti-virus, and IDP (like the ZyWALL UTM products).

• 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).

6.5 Disks

Here is information on the NSA internal disks and external disks attached to the USB port(s).

6.5.1 External Disks

You may connect USB storage devices that support the following file systems to the NSA.

• Windows File Systems: NTFS (read only), FAT32 and FAT16.

If your USB storage device uses a NTFS file system, then the NSA can read files from it, but cannot write files to it. If you want to be able to write files to that storage device, you need to reformat it. You should back up any data on the device that you want to keep (to an internal drive for example) and click the Storage screen's Create an External Volume button to reformat the external hard drive. You can then both read and write to that hard drive and restore your data to it.

Linux File Systems: ReiserFS, EXT2, and EXT3.

6.5.2 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 you put a bigger disk, the extra space on the disk will not be used.

After replacing the disk, go to the Storage > Disk page and click the Repair icon next to the new disk.

The NSA does not repair a disk automatically when you replace it; you must click Repair.

6.5.3 Disk Replacement and Volume Labels

When you create a volume, the NSA writes the volume label to the disk.

Deleting a volume removes volume label information on its disk(s). It is recommended that you first delete a volume before removing its disk(s).

If you do not want to keep the data on a disk that you will remove, it is recommended that you delete the volume before you remove the disk. If you remove a disk(s) without deleting its volume and you later put the disk(s) back in a different volume, you may have more than one volume with the same name. For example, suppose you have two disks, Disk A and Disk B and you create two JBOD volumes, volume1 (with Disk A) and volume2 (Disk B). Later you remove Disk A and replace it with another disk, Disk C and you re-create volume1. (You did not delete volume1 when you removed Disk A.) Later you replace Disk B with Disk A. Disk A still retains the volume1 label, so at this point both Disk A and Disk C have the volume1 label. Although you can still use the volumes, you may find the naming confusing.

6.6 Creating a New Internal Volume

Click the Create a New Internal Volume button in the Volume screen as shown in Figure 38 on page 61 to create a new NSA internal disk drive volume.

Network Screen

This chapter discusses the network configuration screen.

7.1 Network Settings

Use the network configuration screen to assign the NSA a dynamic or static IP address and DNS information.

7.1.1 IP Address

The NSA needs an IP address to communicate with the media servers 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.

7.1.2 DNS Server Address

A DNS (Domain Name System) server maps domain names (like www.zyxel.com) to their corresponding IP addresses (204.217.0.2 in the case of www.zyxel.com). 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.

7.2 Network Config Screen

Click Network in the navigation panel to open the following screen.

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

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

Application Screens

This chapter discusses the application screens.

8.1 Application Screens

Use the application screens to:

• Enable FTP file transfer to/from the NSA, set the number of FTP connections allowed and an FTP idle timeout.
• Enable or disable the media server and select which shares to publish (share with media clients).

8.2 FTP

File Transfer Protocol (FTP) is an Internet file transfer service that operates on the Internet and over TCP/IP networks. A system running the FTP server accepts commands from a system running an FTP client. The service allows users to send commands to the server for uploading and downloading files.

• 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.
• FTP is not a secure protocol. Your file transfers could be subject to snooping.

8.3 FTP Screen

Click Applications > FTP to open the following screen.

Use the FTP screen to configure your NSA FTP settings. In this screen you can enable or disable FTP, set a connection limit, idle timeout, and enable or disable anonymous FTP access. See Section 8.2 on page 77 for more details on FTP.

8.4 Media Server

The NSA can function as a media server where you store multimedia files (videos, music, and photos). By default, computers on your network can use media client software (included on the CD) to play multimedia files stored in the Public, Video, Music and Photo shares (you can also apply the multimedia server function to other shares). Hardware-based media clients like the DMA-1000 can also play the files. See Appendix A on page 126 for the supported multimedia file formats.

The NSA provides no security for the multimedia server function. Any DLNA-compliant media client on your network can play the multimedia files.

Protecting Your Data

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

12.1 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 42 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 malfunction Network down Natural 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 6.4 on page 65 for more information on RAID.

12.1.1 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 reset the device to go back to the factory default configuration.

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

12.1.2 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.

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

Media Client Software

This chapter introduces the media client software included on the CD.

13.1 Media Client Introduction

The NSA can function as a server to allow DLNA (Digital Living Network Alliance) compliant media clients to play files. The DLNA is a group of leading personal computer and electronics companies that works to make products compatible and able to work in a home network in order to make digital living easy and seamless. The group's members include Nokia, Intel, Microsoft, Sony, Motorola, Philips, Samsung, Matsushita, and Hewlett-Packard.

Install the included DLNA-compliant media client software on your Windows XP computers to let them browse and play files stored on the NSA.

• The software requires Windows XP.
• See the Quick Start Guide for how to install the media client software and the requirement details.

13.2 Using the Media Client Software

Refer to the Quick Start Guide and the help (Start > All Programs > DigiOn > Help) for details on how to use the media client software.

Memeo Autobackup Software

This chapter introduces the Memeo Autobackup software included on the CD.

14.1 Memeo Autobackup Introduction

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. You can have Memeo backup specific files, folders of files, or types of files.

Install the included DLNA-compliant Memeo Autobackup software on your Windows 2000 or later computers to let them browse and play files stored on the NSA.

• The software requires Windows XP.
• See the Quick Start Guide for how to install the Memeo Autobackup software and the requirement details.

14.2 Using the Memeo Autobackup Software

Refer to the Quick Start Guide for how to use the Memeo Autobackup software. The software also includes help that you can display by clicking the help link in the screens.

Troubleshooting

15.1 Troubleshooting Overview

This chapter offers some suggestions to solve problems you might encounter. The potential problems are divided into the following categories.

• Power, Hardware, Connections, and LEDs
• NSA Login and Access
• Reset the NSA
• I Cannot Access The NSA
• External USB drives
  Media Server Functions

15.2 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 drive

An HDD LED is orange.

Orange 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 orange 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 drive

An HDD LED is red.

Red means the hard drive has failed and the NSA can no longer detect it. Replace the hard drive. See Installing or replacing a hard drive If you are using a RAID I volume, you may still be able to use the volume but you should replace the faulty drive as soon as possible.

Installing or replacing a hard drive

Do not remove or install hard drives while the NSA is turned on. The NSA must be turned off before you remove or install hard drive(s).

1 Turn the NSA off, remove the rear panel and the drive tray and make sure:

• there is a SATA I or SATA 3.0 Gbit/s compatible hard drive installed.
• the hard drive is installed correctly in the drive tray. Push the tray back into NSA drive bay until the screw hole at the top of the drive tray is flush with the drive bay (see the NSA Quick Start Guide and Section 6.5.2 on page 68).
• the hard drive could be faulty. Try a different hard drive or test the original hard drive in a different NSA or computer.

2 If you had to replace the drive, turn on the NSA and go to the Storage Setting 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 1.1.1 on page 26 for a description of NSA LEDs.

15.3 NSA Login and Access

I forgot the server name of the NSA.

• The default server name is nsa220.
• Use the NDU (NSA Discovery Utility) to discover your NSA. If you have admin privileges, you can directly change the IP address of the NSA using the NDU.
• If the server name has changed and you don't have the NDU, see Section 15.3.1 on page 114 to use the RESET button to return the default setting.

I cannot get to the NSA login screen.

• Use the NDU (NSA Discovery Utility) to discover your NSA. If you have admin privileges, you can directly change the IP address of the NSA using the NDU.
• If you used the RESET button, the NSA may have a new IP address. Close and reopen the NDU 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 nsa220, 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 NDU.

• Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide and Section 1.1.1 on page 26.

• 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 Chapter 7 on page 73 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 NDU to find the NSA's IP address. See Appendix B on page 129 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 NDU 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 JavaScripts and Java enabled. See Appendix C on page 143. With Internet Explorer 6, you may also have to enable scripting of safe ActiveX controls. See Section 15.3.2 on page 115.

15.3.1 Reset the NSA

If you forget your password or cannot access the web configurator, use the RESET button at the rear of the NSA.

15.3.1.1 Using the Reset Button

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 NDU 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 - see Section 15.3.1 on page 114.

The NDU cannot discover my NSA.

• Confirm that the computer running the NDU has a network connection. See the section on the NSA's LAN connection for related information.

• The computer running the NDU can only discover NSAs in the same subnet. NSAs connected to the same switch or router as your NDU 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 NDU to discover the NSA. To avoid a port conflict, do not run the Memeo Autobackup program at the same time as the NDU.
• Close the NDU and reopen it.

15.3.2 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 60 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 61 Security Settings - Script Safe ActiveX Controls

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 15.3.1 on page 114 to reset the device.

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

Use Section 15.3.2 on page 115 to enable the scripting of safe ActiveX controls.

15.4 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 NDU to discover it.
• 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 15.2 on page 111.

• 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.

15.5 External USB drives

My external USB drive is read-only.

If your USB drive was formatted as NTFS, then it is read-only on the NSA (the volume status displays as OK). To solve this problem, re-format your USB drive using the NSA (or FAT or FAT32 using a computer). See Chapter 6 on page 61 for information on volume creation using the NSA (recommended). Back up the files on your computer before you format the USB drive.

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).

15.6 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 Appendix A on page 126 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 Appendix A on page 126 for the file formats that the media server supports.
2 If you are using media client software, you may need to install CODEs on your computer. Since the media client software uses your computer's installed CODEs, 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.

Feature Tables

Physical Features

These are the main external physical features.

Table 43 Physical Features

USB Ports	2 USB (version 2) ports. Copy files directly to the NSA from compatible USB devices like card readers, MP3 players, memory sticks, and digital cameras without using a computer. Expand the NSA's storage capacity with compatible USB devices (like hard drives).
Gigabit Ethernet Port	The 10/100/1000 Mbps auto-negotiating Ethernet port allows the NSA to detect the speed of incoming transmissions and adjust appropriately without manual intervention. It allows data transfer of either 100 Mbps or 1000 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network. Use an 8-wire Ethernet cable for Gigabit connections. The port is also auto-crossover (MDI/ MDI-X) meaning it automatically adjusts to either a crossover or straight-through Ethernet cable.
SATA Interface	Serial ATA is a low cost interface technology that allows high speed data transfer. Serial ATA also allows more efficient internal airflow and also smaller chassis design.
Reset Button	If you forget your (admin) password, then use the reset button to restore the factory default password to “1234” (with username “admin”), and auto-IP address (DHCP client).

Firmware Features

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

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

• If you have a static IP address, enter static in the BOOT proto = 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.

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.

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 re-link 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 COOPYING, 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 accessories, 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 relent 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.

4. 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.

5. 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.
3. 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 NOW 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 WARRANTYES 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.

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

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

59 Temple Place - Suite 330, Boston, MA 02111-1307, USA

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 re-distributors 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 COOPYING, 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 WARRANTYES 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.

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 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. 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 unscrupulous) reasonably calculated to inform those who received the Covered Code that new knowledge has been obtained.

(b) Contributor Apes

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 Sections 3.1, 3.2, 3.3, 3.4 and 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.

5. 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.

6. 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", "MOZILLA", "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-infringing. 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 licenses 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:

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.

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.

10. 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.

11. 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". "Multiple-Licensed" means that the Initial Developer permits you to utilize portions of the Covered Code under Your choice of the MPL or the alternative licenses, if any, specified by the Initial Developer in the file described in Exhibit A.

Exhibit A - Mozilla Public License.
