Configuring Your NAS Now that everything is connected and powered on, you are ready to configure your NAS so that it is acces-sible to the users on your network. • This procedure only needs to be done ONCE, by the NAS Server's Administrator. • Other LAN users should follow the Client PC Setup procedure described in the following chapter. Quick Setup with the NAS Wizard 1. Insert the NAS CD into your CD-ROM drive of your computer. 2. If the installation program does not start automatically, run the program NAS_Setup.exe in the root (top) folder of your CD-ROM. 3. Click "Setup" to start the Setup Utility. The Utility will begin scanning your network for installed NASs, and a screen like the following will be displayed. A list of all the NASs on your network will show on the left side. The right side displays details of the currently selected NAS. Page 15
If the desired NAS is not listed, check the following: • The NAS has finished the start up and boot process. • Your PC and the NAS are on the same LAN segment (there is no Router between your PC and the NAS). Otherwise, select the desired NAS, and click the "Next" button. 4. The following screen will then be displayed. Obtain an IP address automatically (DHCP Client) Select this only if your LAN has a DHCP Server. Normally, it is better for servers to use a Fixed IP address (see below_ Page 16
Fixed IP Address This option is recommended. If this option is used, the IP address or the NAS will never change. You need to enter the following data. • IP address - The utility will suggest a unused IP address within the address range used on your LAN. If you wish, you can change this, but you must ensure the address is unused. • Network Mask - This must match the value used by PCs on your LAN. • Gateway - This must match the value used by PCs on your LAN. 5. Click "Next" to continue. The following screen will then be displayed: The following data is required. Server Name: The Default Name is shown. Change this if you wish. Workgroup Name: Normally, this name should match the Workgroup name used by PCs on your LAN. Page 17
Time Zone Select your time zone from the list. Local Date/Time Enter the local date (mm/dd/yyyy format) and time. 6. Click "Next" to continue. The following screen is displayed. 7. Click "Save" to save your data to the NAS. On the resulting screen, click "Exit" to close the Setup Utility. The NAS is now operational. Other Configuration After the configuration above, all Windows users can access the NAS with "guest" access rights. This allows access to the public shares (by default, DISK and FLASH or USB HDD). However, we recommend creating an NAS "User" for each person on your LAN. This will provide each person on your LAN with their own login (name and password) as well as their own personal folder on the NAS. See the Administration chapter for details on creating users via the Web-based interface. Page 18
Client PC Setup Overview Supported versions of Windows are: • Windows 95/98/ME or later • Windows NT 4.0, Windows 2000, and Windows XP The following items need to be checked or configured: • Network Logon (Windows 95/98/ME only) • Locating the NAS on your LAN. • Mapping to the NAS Server's storage. Page 19
Network Logon (Windows 95/98/ME only) If using Windows 95, Windows 98, or Windows ME, you must Logon to the Network correctly in order to use the NAS. To check your Network Logon, following this procedure: 1. Check your Window logon using Start - Settings - Control Panel - Network. Ensure the Primary Network Logon is set to "Client for Microsoft Networks", as shown below. Window Logon 2. Windows will prompt you to Logon to the Network when it starts (boots). You must logon ! If you press ESC, or click Cancel, no network resources will be available. When you logon, you need to use a valid User Name and Password. If the NAS Administrator has defined users on the NAS, use the User Name and password they supply. Page 20
Using the NAS Server's Storage To use the NAS Server's storage, you should "Map" a drive letter to each folder on the NAS folder which you wish to access. The "Network Drive" will then be available to all Windows programs. The procedure is as follows: 1. Open Network Neighborhood (or My Network Places). 2. On the "View" menu, select Details. The Comment column will now be visible. 3. Locate the NAS, as shown below. If it is not listed, double-click Entire Network. Then double-click the Workgroup that the NAS is in. (By default, the NAS is in Workgroup.) Network Browse 4. Double click on the NAS icon. You will then see a list of shares (shared folders). You can read and write files to these shares, unless the NAS administrator has blocked access. Page 21
5. To create a shortcut to an NAS folder, drag its icon to the desktop, and accept Windows offer to create a shortcut. Mapping a Network Drive You can give a share (shared folder) on the NAS a drive letter on your PC, such as "F:" This is called "mapping" the drive letter. To do this, follow this procedure: 1. Right-click on the desired share on the NAS. 2. On the pop-up menu, select "Map Network Drive..." Map Network Drive 3. Select a drive letter for this folder, check the Reconnect at Logon checkbox, then click "OK". 4. This drive will now be available in Windows Explorer, and from the File- Open or File-Save As dialog in all Windows applications. Page 22
Notes: When you try to access a folder, you may be prompted for a password, as shown below: Network Resource Password Dialog • If your Windows logon name is the same as your user name on the NAS, but the passwords are differ-ent, you can enter your NAS password here. • But if your Windows logon name does not exist on the NAS, you will have only guest access rights, and there is no password which you can enter in this dialog. You must ask the NAS administrator to create a username and password for you on the NAS. • Even if your username and password are correct, you can't gain access if the NAS administrator has not allowed access. Page 23
Tips for Storing Data on the NAS • Change your Windows logon so it matches the user name & password assigned to you on the NAS. This will allow you to login only once. • You can "map" multiple folders to drive letters on your PC, as described above. • You can backup your data to the NAS by copying files from your PC to the NAS. • If you have Windows ME, 2000, or XP, there is a backup program supplied with Windows. You can use this backup program to automate the process of backing up your data to the NAS. Please read the instructions and help file supplied with this program for details of correct usage. Page 24

Wireless Screen This screen allows you to set the wireless function. Wireless Function Enable Wireless Func-tion Can use it to disable/enable Wireless Function. Page 42
Wireless Settings Network Type Select Infrastructure mode if you are connecting the server to a network Access Point. Choose Access Point mode if the server will acts as one Access Point. SSID The network name is a value that identifies a collection of wireless devices found in a particular network. The default value for the Wireless Broadband Router is "wireless". All worksta-tions and access points must use the same SSID to be able to communicate with one another. The SSID is a 32-character field, and the value is case sensitive. For example, your street address or some other identifier of the physical location of the WLAN, your name, your company name, or the company name and department, a favorite slogan or saying, etc. Broadcast SSID This option only works in Access Point mode. If checked, the server will broadcast its SSID in the wireless network, and not if unchecked. Channel No Select the appropriate channel from the list provided to corre-spond with your network settings, between 1 and 11 (in North America). All devices in your wireless network must use the same channel in order to function correctly. Wireless Security WEP If you wish to enable WEP encryption, select WEP in the Wireless Security list. Page 43
WPA If you wish to enable WPA encryption, select WPA in the Wireless Security list. WEP WEP An acronym for Wired Equivalent Privacy, WEP is an encryp-tion method used to protect your wireless data communications. WEP uses 64-bit or 128-bit keys to provide access control to your network and encryption security for every data transmis-sion. To decode a data transmission, each device in a network must use an identical WEP key. Higher encryption levels offer higher levels of security, but due to the complexity of the encryption, they may decrease network performance. Authentication The default is set to Open System, in which the sender and the recipient do NOT use a WEP key for authentication. Shared Key is when the sender and recipient use a WEP key for authen-tication. To disable WEP encryption, keep the default setting, Disable. WEP Encryption An acronym for Wired Equivalent Privacy, WEP is an encryp-tion method used to protect your wireless data communications. WEP uses 64-bit or 128-bit keys to provide access control to your network and encryption security for every data transmis-sion. To decode a data transmission, each device in a network must use an identical WEP key. Select the level of WEP encryption you wish to use, 64-bit or 128-bit. Higher encryption levels offer higher levels of security, but due to the complexity of the encryption, they may decrease network performance. Page 44
Default Transmit Key Select which WEP key (1-4) will be used when the Access Point sends data. Make sure the receiver is using the same key. Key 1 ~ Key 4 WEP keys enable you to create an encryption scheme for wire-less LAN transmissions. Manually enter a set of values. (Do not leave a key field blank, and do not enter all zeroes. These are not valid key values.) If you are using 64-bit WEP encryption, then each key must consist of exactly 10 hexadecimal characters in length. If you are using 128-bit WEP encryption, then each key must consist of exactly 26 hexadecimal characters in length. Valid hexadecimal characters are "0"-"9" and "A"-"F". WPA WPA WPA is an upgrade to the WEP (Wired Equivalent Privacy) standard for securing your wireless network. Pre-Shared Key WPA Pre-Shared Key (PSK) is a field where the password is entered. All wireless clients must also use this password to gain access to the network. Note that the Key format must also match the setting for the wireless clients. Its length rangs from 8bytes to 63bytes. Group Rekey Interval WPA Group Rekey Interval is used to specify the frequency of encryption key rotations. The lower the number, the faster your encryption key will rotate, however, setting this number too low may cause your wireless network to slow down. Page 45
Encryption WPA Encryption has 2 choices: TKIP (Temporal Key Integrity Protocol) - it is the most commonly used encryption method and AES (Advanced Encryption Standard) - it can be used if your wireless clients do not support TKIP. Page 46
LAN Screen This screen allows you to set the IP Address and related information required for TCP/IP networks. • Wireless Access Point: If you are using this device as a Wireless Access Point, IP Address = The IP Address of the NAS. DHCP server = The IP Address range that the NAS will serve out to the client that is wirelessly connected.

LAN (TCP/IP) Screen IP Address Obtain IP Address automatically (DHCP Client) Do NOT select this unless you have a DHCP Server on your LAN. A DHCP Server can provide an IP Address to PCs and other devices when they boot. Fixed IP Address Select this if your LAN does not have a DHCP Server, and enter the following data. Page 48
IP Address: (Default:192.168.0.100) The IP Address must be unused, and compatible with the PCs on your LAN. Usually, this means the first 3 fields should be the same as your PC, and the last field must be an unused number between 1 and 254. Network Mask: (Default:255.255.255.0) Enter the same Network Mask (Subnet Mask) used by PCs on your LAN. Gateway (Router): Default: None If your LAN has a Router or Gateway, enter its IP Address here. Otherwise, leave this blank. DHCP Server Enable Use this to Enable/Disable the DHCP Server. If you already have a DHCP Sever, do not enable this feature. Start Address Enter the beginning of the range of IP Addresses to be allocated by the DHCP Server. Generally, the first 3 fields of the IP Address must match the NAS Server's IP Address. The 4th field must be between 2 and 250. Finish Address Enter the last address of range of IP Addresses to be allocated by the DHCP Server. The first 3 fields must match the corre-sponding field in the "Start IP Address". DNS Server Primary IP Address of the first DNS Server. Backup IP Address of the DNS Server to be tried if the first server is busy. Page 49

The NAS Server will set its own clock according to the time you provide. Remember that this is not sent to the Server until you click "OK". NTP Enable NTP If enabled, the NAS Server will synchronize its clock with a NTP (Network Time Protocol) Server. NTP Server Enter the domain name or IP address of the NTP server you wish to use. The NTP server can be a public server (on the Internet) or a local server (on your own network). NTP Status This shows the status of the NTP update procedure. Synchronize ... Select how often you want the NAS Server to synchronize its clock with the specified NTP server. You can also specify the time of the next synchronization. This allows you to specify that the synchronization should be performed (for example) at 11.00 pm each day. Sync Now Use this button to synchronize with the NTP server immediately. Page 52
WINS Server Enable WINS Enable this if your LAN has a WINS Server. If enabled, this device will register with the WINS Server. This will allow users on the LAN to locate this device through a Router. (Without WINS, "Network Neighborhood" or "My Network Places" only scans the local LAN segment.) WINS Server If WINS is enabled, enter the IP Address of your WINS Server. Normally, this will be a Windows NT/2000/XP Server. Options Enable Guest Logins If enabled, then the user can use "guest" as user ID to login to the NAS. If disabled, then "guest" will not be accepted as a login. Convert failed logins to "guest" logins If enabled, then all Windows users will be able to access the NAS via Network Neighborhood/My Network Places, with "guest" access rights. By default, the "guest" user has Read/Write per-mission to the "Disk" folder on the USB HDD, and all folders on the Flash Drive. Enable FTP Server If enabled, then it will be possible for users to upload and download files using a FTP client program on their PC. Allow anonymous FTP login (“guest” right) The FTP server will prompt for a Username and Password when clients attempt to connect. If this option is Enabled, users will be able to enter "anonymous" as the Username, and any string as the Password. If this option is Disabled, users must provide their correct Name and Password. Page 53
Enable UPnP Support If enabled, the NAS will broadcast its availability. On systems which support UPnP (e.g. Windows ME, XP), an icon for the NAS will be automatically generated. Port Number.. This port number is used for HTTP (Web Browser) connections to this Server. The default is 80, as used by Web Servers. If this is changed, you should use a number greater than 1024 (8080 is often used). Also, if the port is not 80, you must specify the port in your Web browser, in order to connect. To do this, add a ":" and the port number after the address: e.g. HTTP://192.168.0.100:8080 This example assumes the NAS IP Address is 192.168.0.100, and the port number is 8080.

NAS via the Internet Overview If your LAN is connected to the Internet, typically by a Broadband Gateway/Router and Broadband modem, you can make the NAS available via the Internet. Features available to Internet users include: • Using a Web browser to view and download files. • Remote management Making the NAS available via the Internet If your LAN is connected to the Internet via a Router or Gateway, you can make the NAS available from the Internet. No changes to the NAS configuration are required, unless you wish to use a port number other than the default value of 80 for Web connections. Your Router or Gateway must be configured to pass incoming HTTP connections (and optionally, IPP connections) to the NAS. This feature is normally called Port Forwarding or Virtual Servers, and is illus-trated below. Page 76
Connecting via the Internet • The default port number for Web browser connections is 80. If you prefer to use a different port num-ber, you can specify the port number on the NAS System screen. The "Web" entry for /Port Forwarding / Virtual Server must then use the port number specified on the NAS System screen. • To connect to the NAS, Internet users need to know and use the Internet IP address of your Router/Gateway. (If the port number is not 80, they also need to know the port number.) Page 77
• If you have a domain name, users can connect using the domain name instead of the IP address. If your Router/Gateway supports Dynamic DNS, you can use a domain name even if you get a different IP address every time you connect to your ISP. Check the documentation of your Router/Gateway for further information. Using your Web Browser from the Internet This is identical to using your Web browser from the LAN. See Using the Web File Sharing for details. But remember: • You must use the Internet IP address to connect to the NAS, NOT the LAN IP address. • If the port number used by the NAS has been changed from the default (80), you must specify the correct port number when you connect. For example, if the port is 8080, and the Internet IP address is 203.70.212.52, enter the following as your browser's Address or Location: HTTP://203.70.212.52:8080 Page 78
Printing via IPP (Internet Printing Protocol) To print to the NAS via the Internet, the port used for IPP (TCP port 631) must be associated with the NAS. See Making the NAS available via the Internet earlier in this chapter for details. The NAS is an IPP Server. To use IPP, your PC must be an IPP client. Windows 2000 and XP have built-in support for IPP, so there is no need to use the provided IPP client program. IPP Setup - Windows 2000/XP 1. Start the Add Printer wizard. 2. Select Network Printer, and click "Next" to see the Locate your Printer screen, as shown below. Windows 2000 - Locate your Printer Page 79
3. Select Connect to a printer on the Internet or on your Intranet, and enter the URL of the NAS as follows. http://ip_address:631/printers/printer_name Where: • ip_address represents the IP Address used to access the NAS. (As explained earlier, this may be the Internet address of a Gateway, rather than the NAS itself.) • printer_name is the name of the printer, as set on the NAS System screen. • The other text is fixed, and can NOT be changed. It must be entered exactly as shown, including the same case. (The path is case sensitive.) Example: http://203.70.212.52:631/printers/LKLKG974163_p1 4. Click "Next". If the connection can be established, and the printer on that port is on-line, the following dialog will be displayed. Windows 2000: No printer driver 5. Click "OK", and then select the printer manufacturer and model to match the printer connected to the port on the IPP Server. Page 80
6. Click "Next", and complete the Wizard. The IPP printer is now ready for use. IPP Client Setup (Windows 9x, ME) You need to install the supplied IPP client program, as follows: 1. Insert the NAS CD-ROM in your drive. If the program does not start automatically, run the NAS_Setup.exe program in the top-level folder. 2. On the first screen, click the icon for IPP Client. 3. Follow the prompts to complete the installation. IPP Client Configuration 1. Click the "Add IPP Port" icon. (In future, you can use the program entry created in the Start Menu) 2. A screen like the following will be displayed. Page 81
IPP Port 3. Configure this screen as follows: IPP Server Enter the Internet IP address used to connect to the NAS, as follows. http://ip_address:631/printers/printer_name Where: • ip_address represents the IP Address used to access the NAS. (As explained earlier, this may be the Internet address of a Gateway, rather than the NAS itself.) • printer_name is the name of the printer, as set on the NAS System screen. • The other text is fixed, and can NOT be changed. It must be entered Page 82
exactly as shown. Example: http://203.70.212.52:631/printers/LKLKG974163_p1 Proxy Server If Internet access from your PC is via a Proxy Server, check Access IPP Server via Proxy Server, and enter details of your Proxy Server. (These will be the same as your Browser configuration, so check your Browser settings.) 4. Click Save to create the IPP port on your system. You will see the following dialog: Select Printer for IPP Port Page 83
5. Either select an existing printer to use the new port, and click OK. OR a) Click the "Add New Printer" button to start the Add Printer wizard. b) Complete the Wizard, installing the desired printer as a local printer on your PC. c) When returned to this screen, select the new printer and click OK. 6. The selected printer is now associated with the remote NAS, and installation is complete. Changing the IPP Port Settings After the IPP port is created, you can reach the IPP Port screen via the Windows Port Settings button: 1. Open the Printers folder (Start - Settings - Printers) 2. Right-click the IPP Printer, and select Properties. 3. Locate and click the Port Settings button (on the Details or Port tab, depending on your version of Windows). Using the IPP Printer The IPP Printer can be selected and used like any other Windows printer, but your Internet connection needs to be active. An NAS may be unavailable for IPP printing for any of the following reasons: • It is powered off. • The IP Address of the Router/Gateway for the remote LAN has changed. • The Internet connection used by the IPP Server is down. • Network congestion causes the connection attempt to time out. Page 84
Remote Management Connection via your Web browser from the Internet is the same as connecting via the LAN. But remember: • You must use the Internet IP address to connect to the NAS, NOT the LAN IP address. • If the port number used by the NAS has been changed from the default (80), you must specify the correct port number when you connect. For example, if the port is 8080, and the Internet IP address is 203.70.212.52, enter the following as your browser's Address or Location: HTTP://203.70.212.52:8080 Once connected to the NAS via the Internet, all the Web-based management features are available. However, the "Browse" button on the Shares screen only allows Web-based file browsing. (If using Internet Explorer on Windows, LAN users can Browse shares using Windows Explorer.) Page 85
Troubleshooting This chapter lists some common problems, and the solution to them. Problem 1: The NAS Utility doesn't list any NAS Servers. Solution 1: Check the following: • The NAS is installed, LAN connections are OK, and it is powered ON and startup is complete. • Ensure that your PC and the NAS are on the same network segment. (If you don't have a router, this must be the case.) • Ensure that your PC has the TCP/IP network protocol loaded. In Windows, this is done by using Control Panel-Network. If an entry for TCP/IP -> Network card is not listed, use Add - Protocol - Microsoft - TCP/IP to add it. You then need to select the new entry (TCP/IP -> Network card), click Properties, and configure the IP Address tab. • If your LAN has a DHCP Server, you can select "Obtain an IP Address auto-matically". • Otherwise, you must select "Specify an IP Address", and enter values for IP Address and Subnet Mask. The IP Address range commonly used is 192.168.0.1 to 192.168.0.254, with a Subnet Mask of 255.255.255.0. (The NAS Server's default IP Address is 192.168.0.2, with a Subnet Mask of 255.255.255.0). Remember that each device needs a unique IP Address, and the same Subnet Mask. Problem 2: The NAS is configured, but I can't find it in Network Neighborhood. Solution 2 Try using Start - Find - Computer, and enter the NAS Server's name. If this does not work, use Control Panel - Network to check the following: Page 86
• TCP/IP protocol is installed. If not, use Add - Protocol - Microsoft - TCP/IP to install it. • Check the network Bindings: • Ensure the TCP/IP protocol is bound to your Network card (NIC). Select your Network card, click Properties, and then the Bindings tab. If TCP/IP is not bound (checked), check it. • Ensure the TCP/IP -> Network card entry is bound to the Client for Micro-soft Networks service. Select the TCP/IP entry for your Network Card, click Properties, and then the Bindings tab. If Client for Microsoft Networks is not bound (checked), check it. • If you don't have a router, check that your IP Address is compatible with the NAS Server's. This means it needs to be from the same address range (e.g. 192.168.0.1 to 192.168.0.254) and using the same Subnet Mask (e.g. 255.255.255.0) • If you DO have a router, check that your Gateway IP Address is set correctly. Ask your LAN administrator for the correct value. Problem 3 When I click on an NAS folder icon in Network Neighborhood, I get prompted for a password. Solution 3 This can happen in the following situations: • The Logon name you used on your PC is recognized by the NAS, but the password is not. Simply enter your NAS password, or make your Windows password the same as the NAS password. • The logon name you used on your PC is NOT recognized by the NAS, and was converted to guest, with guest access rights. Ask the NAS Administrator to create a user name for you. (Use the same name as on your PC.) Page 87
• You do NOT have access permission for this share. Ask the NAS Administrator to grant you access. Note: Windows uses the Computer name, as shown on Control Panel - Network - Identification, as the default Logon Name. But you can create a new Windows logon name by merely entering a new name and password at the Logon prompt. Page 88

FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator your body. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may cot cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The antennas used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmit-ter. Channel The Wireless Channel sets the radio frequency used for communication.  Access Points use fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use differ-ent Channels to reduce interference.  In “Infrastructure” mode, Wireless Stations normally scan all Channels, looking for an Access Point. IF more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.) Page 90
 If using “Ad-hoc” mode (no Access Point), all Wireless stations should be ser to use the same Chan-nel. However, most Wireless stations will still scan all Channels to see if there is an existing “Ad-hoc” group they can join. CAUTION: 1) To comply with FCC RF exposure compliance requirements, a separation distance of at least 20 cm must be maintained between the antenna of this device and all persons. 2) This transmitter must not be co-located or operating in conjunction with any other antenna or transmit-ter.

GNU General Public License 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 Page 95
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 soft-ware or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. Page 96
GNU GENERAL PUBLIC LICENSE Terms And Conditions For Copying, Distribution And Modification 0. 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. 1. 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. 2. 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. Page 97
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. 3. 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 Page 98
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. 4. 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. 5. 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 condi-tions for copying, distributing or modifying the Program or works based on it. Page 99
6. 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. 7. 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 consis-tent 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. Page 100
8. 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. 9. 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 condi-tions 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. 10. 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 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN Page 101
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, Page 102
REPAIR OR CORRECTION. 12. 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.
