Wireless AP/Repeater

The Wireless-N Access Point/Repeater is designed as an access point that extends an existing wired network to support wireless users. It also supports use as a wireless repeater/bridge that can extend the range of the network or connect to remote LANs.

This chapter explains some of the basic features of the Wireless-N Access Point/Repeater and shows some network topology examples in which the device is implemented.

LAN ACCESS POINT

The Wireless-N Access Point/Repeater can provide an access point service for an existing wired LAN, creating a wireless extension to the local network.

A Wi-Fi wireless network is defined by its Service Set Identifier (SSID) or network name. Wireless clients that want to connect to a network must set their SSID to the same SSID of the network service.

Wireless Bridge

The IEEE 802.11 standard defines a Wireless Distribution System (WDS) for bridge connections between access points. The Wireless-N Access Point/Repeater can use WDS to forward traffic on links between units.

Up to four WDS links can be specified for the Wireless-N Access Point/ Repeater.

The WDS feature enables two basic functions to be configured in the wireless network. Either a repeater function that extends the range of the wireless network, or a bridge function that connects a remote LAN segment to an Internet connection.

Wireless Client

The Wireless-N Access Point/Repeater can operate as a wireless client on one SSID interface, which enables a connection to another Wi-Fi network. When the wireless client option is enabled, the client SSID interface functions as an external gateway WAN port. When the wireless client option is enabled as a LAN connection, the other SSID interface and LAN ports all function as the local network within the same IP subnet.

3 INSTALLING THE ACCESS POINT/

REPEATER

This chapter describes how to install the access point.

SYSTEM REQUIREMENTS

You must meet the following minimum requirements:

◆ An Internet access device (DSL or Cable modem) with an Ethernet port

connection.

◆ An up-to-date web browser: Internet Explorer 6.0 or above or Mozilla

Firefox 2.0 or above.

LOCATION SELECTION

Choose a proper place for the access point/repeater. In general, the best location is at the center of your wireless coverage area, within line of sight of all wireless devices. Try to place the access point in a position that can best cover its service area. For optimum performance, consider these guidelines:

◆ Mount the access point as high as possible above any obstructions in

the coverage area.

◆ Avoid mounting next to or near building support columns or other

obstructions that may cause reduced signal or null zones in parts of the coverage area.

◆ Mount away from any signal absorbing or reflecting structures (such as

those containing metal).The access point can be mounted on any horizontal surface, or a wall.

BASIC SETTINGS

The IEEE 802.11n interface includes configuration options for radio signal characteristics and wireless security features.

The Wireless-N Access Point/Repeater’s radio can operate in six modes, mixed 802.11b/g/n, mixed 802.11b/g, mixed 802.11g/n, 802.11n only,

802.11b only, or 802.11g only. Note that 802.11g is backward compatible with 802.11b, and 802.11n is backward compatible with 802.11b/g at slower data transmit rates.

The Wireless-N Access Point/Repeater supports four virtual access point (VAP) interfaces. One VAP is the primary (Network Name SSID), and the the others are referred to as "Multiple SSID1~SSID3." Each VAP functions as a separate access point, and can be configured with its own Service Set Identification (SSID) and security settings. However, most radio signal parameters apply to all VAP interfaces.

Traffic to specific VAPs can be segregated based on user groups or application traffic. All VAPs can have up to 64 wireless clients, whereby the clients associate with these VAPs the same as they would with a physical access point.

OTE

The radio channel settings for the access point are limited by local regulations, which determine the number of channels that are available.

◆ Broadcast Network Name (SSID) — By default, the Wireless-N

Access Point/Repeater always broadcasts the SSID in its beacon signal. Disabling the SSID broadcast increases security of the network because wireless clients need to already know the SSID before attempting to connect. When set to disable, the Network Name SSID, and SSID1~SSID3 are automatically set to “Hide.” (Default: Enabled)

◆ AP Isolation — The Wireless-N Access Point/Repeater will isolate

communincation between all clients in order to protect them. Normally for users who are at hotspots. (Default: Disable)

◆ MBSSID AP Isolation — The Wireless-N Access Point/Repeater will

isolate wireless clients from different SSID. (Default: Disable)

◆ BSSID — The identifier (MAC address) of the Wireless-N Access Point/

Repeater in the Basic Service Set (BSS) network.

◆ Frequency (Channel) — The radio channel that the Wireless-N Access

Point/Repeater uses to communicate with wireless clients. When multiple access points are deployed in the same area, set the channel on neighboring access points at least five channels apart to avoid interference with each other. For example, you can deploy up to three access points in the same area using channels 1, 6, 11. Note that wireless clients automatically set the channel to the same as that used by the Wireless-N Access Point/Repeater to which it is linked. Selecting Auto Select enables the Wireless-N Access Point/Repeater to automatically select an unoccupied radio channel. (Default: AutoSelect)

HT PHYSICAL MODE

SETTINGS

The HT Physical Mode section on the Wireless Settings Advanced page includes additional parameters for 802.11n operation.

Figure 19: HT Physical Mode Settings

The following items are displayed in this section on this page:

◆ Channel Bandwidth — The Wireless-N Access Point/Repeater

provides a channel bandwidth of 40 MHz by default giving an 802.11g connection speed of 108 Mbps (sometimes referred to as Turbo Mode) and a 802.11n connection speed of up to 150 Mbps. Setting the HT Channel Bandwidth to 20 MHz slows connection speed for 802.11g and

802.11n to 54 Mbps and 74 Mbps respectively and ensures backward compliance for slower 802.11b devices. (Default: 20MHz)

◆ Guard Interval — The guard interval between symbols helps receivers

overcome the effects of multipath delays. When you add a guard time, the back portion of useful signal time is copied and appended to the front. (Default: Auto)

◆ MCS — The Modulation and Coding Scheme (MCS) is a value that

determines the modulation, coding and number of spatial channels. (Options: value [range] = 0~7 (1 Tx Stream), 8~15 (2 TxStream), 32 and auto (33). Default: Auto)

◆ Reverse Direction Grant (RDG) — When Reverse Direction Grant is

enabled, the Wireless-N Access Point/Repeater can reduce the transmitted data packet collision by using the reverse direction protocol. During TXOP (Transmission Opportunity) period, the receiver could use remaining transmission time to transmit data to a sender. The RDG improves transmission performance and scalability in a wireless environment. (Default: Enabled)

HAPTER

| Access Point Mode Wireless Configuration

Advanced Settings

The following items are displayed in this section on this page:

◆ BG Protection Mode — Enables a backward compatible protection

mechanism for 802.11b clients. There are three modes: (Default: Auto)

■

Auto — The unit enables its protection mechanism for 802.11b clients when they are detected in the network. When 802.11b clients are not detected, the protection mechanism is disabled.

■

On — Forces the unit to always use protection for 802.11b clients, whether they are detected in the network or not. Note that enabling b/g Protection can slow throughput for 802.11g/n clients by as much as 50%.

■

Off — Forces the unit to never use protection for 802.11b clients. This prevents 802.11b clients from connecting to the network.

◆ Beacon Interval — The rate at which beacon signals are transmitted

from the access point. The beacon signals allow wireless clients to maintain contact with the access point. They may also carry powermanagement information. (Range: 20-999 TUs; Default: 100 TUs)

◆ Data Beacon Rate (DTIM) — The rate at which stations in sleep

mode must wake up to receive broadcast/multicast transmissions.

Known also as the Delivery Traffic Indication Map (DTIM) interval, it indicates how often the MAC layer forwards broadcast/multicast traffic, which is necessary to wake up stations that are using Power Save mode. The default value of one beacon indicates that the access point will save all broadcast/multicast frames for the Basic Service Set (BSS) and forward them after every beacon. Using smaller DTIM intervals delivers broadcast/multicast frames in a more timely manner, causing stations in Power Save mode to wake up more often and drain power faster. Using higher DTIM values reduces the power used by stations in Power Save mode, but delays the transmission of broadcast/multicast frames. (Range: 1-255 beacons; Default: 1 beacon)

◆ Fragmentation Threshold – Configures the minimum packet size that

can be fragmented when passing through the access point. Fragmentation of the PDUs (Package Data Unit) can increase the reliability of transmissions because it increases the probability of a successful transmission due to smaller frame size. If there is significant interference present, or collisions due to high network utilization, try setting the fragment size to send smaller fragments. This will speed up the retransmission of smaller frames. However, it is more efficient to set the fragment size larger if very little or no interference is present because it requires overhead to send multiple frames. (Range: 2562346 bytes; Default: 2346 bytes)

◆ RTS Threshold — Sets the packet size threshold at which a Request to

– 45 –

HAPTER

| Access Point Mode Wireless Configuration

Advanced Settings

After receiving an RTS frame, the station sends a CTS (clear to send) frame to notify the sending station that it can start sending data.

If the RTS threshold is set to 0, the access point always sends RTS signals. If set to 2347, the access point never sends RTS signals. If set to any other value, and the packet size equals or exceeds the RTS threshold, the RTS/CTS (Request to Send / Clear to Send) mechanism will be enabled.

The access points contending for the medium may not be aware of each other. The RTS/CTS mechanism can solve this “Hidden Node Problem.” (Range: 1-2347 bytes: Default: 2347 bytes)

◆ TX Power — Adjusts the power of the radio signals transmitted from

the access point. The higher the transmission power, the farther the transmission range. Power selection is not just a trade off between coverage area and maximum supported clients. You also have to ensure that high-power signals do not interfere with the operation of other radio devices in the service area.

◆ Short Preamble — Sets the length of the signal preamble that is used

at the start of a data transmission. Use a short preamble (96 microseconds) to increase data throughput when it is supported by all connected 802.11g clients. Use a long preamble (192 microseconds) to ensure all 802.11b clients can connect to the network. (Default: Disable)

◆ Short Slot — Sets the basic unit of time the access point uses for

calculating waiting times before data is transmitted. A short slot time (9 microseconds) can increase data throughput on the access point, but requires that all clients can support a short slot time (that is, 802.11gcompliant clients must support a short slot time). A long slot time (20 microseconds) is required if the access point has to support

802.11b clients. (Default: Enabled)

◆ TX Burst — A performance enhancement that transmits a number of

data packets at the same time when the feature is supported by compatible clients. (Default: Enabled)

◆ Packet Aggregate — A performance enhancement that combines data

packets together when the feature is supported by compatible clients. (Default: Enabled)

WI-FI MULTIMEDIA The Wireless-N Access Point/Repeater implements Quality of Service (QoS)

using the Wi-Fi Multimedia (WMM) standard. Using WMM, the access point is able to prioritize traffic and optimize performance when multiple applications compete for wireless network bandwidth at the same time. WMM employs techniques that are a subset of the developing IEEE 802.11e QoS standard and it enables access points to interoperate with both WMMenabled clients and other devices that may lack any WMM functionality.

– 46 –

HAPTER

| Access Point Mode Wireless Configuration

Advanced Settings

WMM defines four access categories (ACs): voice, video, best effort, and background. These categories correspond to traffic priority levels and are mapped to IEEE 802.1D priority tags (see Tab le 3). The direct mapping of the four ACs to 802.1D priorities is specifically intended to facilitate interoperability with other wired network QoS policies. While the four ACs are specified for specific types of traffic, WMM allows the priority levels to be configured to match any network-wide QoS policy. WMM also specifies a protocol that access points can use to communicate the configured traffic priority levels to QoS-enabled wireless clients.

MULTICAST-TO-

UNICAST CONVERTER

The Multicast-to-Unicast Converter section on the Wireless Settings Advanced page allows you to enable multicast traffic conversion.

Converting multicast traffic to unicast before sending to wireless clients allows a longer DTIM (Data Beacon Rate) interval to be set. A longer DTIM interval prevents clients in power-save mode having to activate their radios to receive the multicast data, which saves battery life.

The following items are displayed in this section on this page:

◆ Multicast-to-Unicast — Enables multicast traffic streams to be

WLAN SECURITY

The Wireless-N Access Point/Repeater’s wireless interface is configured by default as an “open system,” which broadcasts a beacon signal including the configured SSID. Wireless clients with a configured SSID of “ANY” can read the SSID from the beacon, and automatically set their SSID to allow immediate connection to the wireless network.

To implement wireless network security, you have to employ one or both of the following functions:

◆ Authentication — It must be verified that clients attempting to

connect to the network are authorized users.

◆ Traffic Encryption — Data passing between the unit and clients must

be protected from interception and eavesdropping.

WIRED EQUIVALENT

PRIVACY (WEP)

WEP provides a basic level of security, preventing unauthorized access to the network, and encrypting data transmitted between wireless clients and an access point. WEP uses static shared keys (fixed-length hexadecimal or alphanumeric strings) that are manually distributed to all clients that want to use the network.

When you select to use WEP, be sure to define at least one static WEP key for user authentication or data encryption. Also, be sure that the WEP shared keys are the same for each client in the wireless network.

The following items are displayed in this section on this page:

Security Mode — Configures the WEP security mode used by clients. When using WEP, be sure to define at least one static WEP key for the Wireless-N Access Point/Repeater and all its clients. (Default: Disable)

◆ OPEN — Open-system authentication accepts any client attempting to

connect the Wireless-N Access Point/Repeater without verifying its identity. In this mode the default data encryption type is “WEP.”

◆ SHARED — The shared-key security uses a WEP key to authenticate

◆ WEP-AUTO — Allows wireless clients to connect to the network using

Open-WEP (uses WEP for encryption only) or Shared-WEP (uses WEP for authentication and encryption).

◆ Encrypt Type — Selects WEP for data encryption (OPEN mode only).

◆ Default Key — Selects the WEP key number to use for authentication

or data encryption. If wireless clients have all four WEP keys configured to the same values, you can change the encryption key to any of the settings without having to update the client keys. (Default: 1; Range: 1~4)

WPA PRE-SHARED

KEY

Wi-Fi Protected Access (WPA) was introduced as an interim solution for the vulnerability of WEP pending the adoption of a more robust wireless security standard. WPA2 includes the complete wireless security standard, but also offers backward compatibility with WPA. Both WPA and WPA2 provide an “enterprise” and “personal” mode of operation.

For small home or office networks, WPA and WPA2 provide a simple “personal” operating mode that uses just a pre-shared key for network access. The WPA Pre-Shared Key (WPA-PSK) mode uses a common password phrase for user authentication that is manually entered on the access point and all wireless clients. Data encryption keys are automatically generated by the access point and distributed to all clients connected to the network.

Figure 26: Security Mode - WPA-PSK

The following items are displayed in this section on this page:

Security Mode — Configures the WPA-PSK and WPA2-PSK security modes used by clients. When using WPA-PSK or WPA2-PSK, be sure to define the shared key for the Wireless-N Access Point/Repeater and all its clients. (Default: Disable)

■

AES — Uses Advanced Encryption Standard (AES) keys for encryption. WPA2 uses AES Counter-Mode encryption with Cipher Block Chaining Message Authentication Code (CBC-MAC) for message integrity. The AES Counter-Mode/CBCMAC Protocol (AESCCMP) provides extremely robust data confidentiality using a 128bit key. Use of AES-CCMP encryption is specified as a standard requirement for WPA2. Before implementing WPA2 in the network, be sure client devices are upgraded to WPA2-compliant hardware.

■

TKIP/AES — Uses either TKIP or AES keys for encryption. WPA and WPA2 mixed modes allow both WPA and WPA2 clients to associate to a common SSID. In mixed mode, the unicast encryption type (TKIP or AES) is negotiated for each client.

encryption. WPA2 uses AES Counter-Mode encryption with Cipher Block Chaining Message Authentication Code (CBC-MAC) for message integrity. The AES Counter-Mode/CBCMAC Protocol (AESCCMP) provides extremely robust data confidentiality using a 128bit key. Use of AES-CCMP encryption is specified as a standard requirement for WPA2. Before implementing WPA2 in the network, be sure client devices are upgraded to WPA2-compliant hardware.

■

◆ Key Renewal Interval — Sets the time period for automatically

changing data encryption keys and redistributing them to all connected clients. (Default: 3600 seconds)

◆ PMK Cache Period — WPA2 provides fast roaming for authenticated

clients by retaining keys and other security information in a cache, so that if a client roams away from an access point and then returns reauthentication is not required. This parameter sets the time for deleting the cached WPA2 Pairwise Master Key (PMK) security information. (Default: 10 minutes)

IEEE 802.1X AND

RADIUS

◆ Pre-Authentication — When using WPA2, pre-authentication can be

enabled that allows clients to roam to another access point and be quickly associated without performing full 802.1X authentication. (Default: Disable)

IEEE 802.1X is a standard framework for network access control that uses a central RADIUS server for user authentication. This control feature prevents unauthorized access to the network by requiring an 802.1X client application to submit user credentials for authentication. The 802.1X standard uses the Extensible Authentication Protocol (EAP) to pass user credentials (either digital certificates, user names and passwords, or other) from the client to the RADIUS server. Client authentication is then verified on the RADIUS server before the client can access the network.

Remote Authentication Dial-in User Service (RADIUS) is an authentication protocol that uses software running on a central server to control access to RADIUS-aware devices on the network. An authentication server contains a database of user credentials for each user that requires access to the network.

The WPA and WPA2 enterprise security modes use 802.1X as the method of user authentication. IEEE 802.1X can also be enabled on its own as a security mode for user authentication. When 802.1X is used, a RADIUS server must be configured and be available on the connected wired network.

WIRELESS DISTRIBUTION SYSTEM (WDS)

The radio interface can be configured to operate in a mode that allows it to forward traffic directly to other Wireless Access Point/Repeater units. This feature can be used to extend the range of the wireless network to reach remote clients, or to link disconnected network segments to an Internet connection.

To set up links between units, you must configure the Wireless Distribution System (WDS) forwarding table by specifying the wireless MAC address of all units to which you want to forward traffic.

OTE

All units in a WDS wireless network must be configured with the same SSID and use the same radio channel. Also each WDS link must be configured with the same encryption key on both units in the link.

Up to four WDS links can be specified for each unit in the WDS network. The following figures illustrate an example WDS network. Figure 30 shows the manual set up of MAC addresses for units in the WDS network.

used at the start of a data transmission. Use a long preamble (192 microseconds) to ensure connection to all 802.11b devices. When set to Auto, a short (96 microseconds) or long preamble will be used depending on the capabilities of other Ad Hoc network devices. (Only available when “Ad hoc” is selected as the network type.) (Default: Auto)

◆ RTS Threshold — Sets the packet size threshold at which a Request to

Send (RTS) signal must be sent to a receiving station prior to the sending station starting communications. The access point sends RTS frames to a receiving station to negotiate the sending of a data frame. After receiving an RTS frame, the station sends a CTS (clear to send) frame to notify the sending station that it can start sending data. If the RTS threshold is set to 0, the access point always sends RTS signals. If set to 2347, the access point never sends RTS signals. If set to any other value, and the packet size equals or exceeds the RTS threshold, the RTS/CTS (Request to Send / Clear to Send) mechanism will be enabled. The access points contending for the medium may not be aware of each other. The RTS/CTS mechanism can solve this “Hidden Node Problem.” (Range: 0-2347 bytes)

◆ Fragment Threshold — Configures the minimum packet size that can

be fragmented when passing through the access point. Fragmentation of the PDUs (Package Data Unit) can increase the reliability of transmissions because it increases the probability of a successful transmission due to smaller frame size. If there is significant interference present, or collisions due to high network utilization, try setting the fragment size to send smaller fragments. This will speed up the retransmission of smaller frames. However, it is more efficient to set the fragment size larger if very little or no interference is present because it requires overhead to send multiple frames. (Range: 2562346 bytes; Default: 2346 bytes)

C CABLES AND PINOUTS

TWISTED-PAIR CABLE ASSIGNMENTS

For 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.

OTE

Each wire pair must be attached to the RJ-45 connectors in a specific orientation.

AUTION

only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

DO NOT plug a phone jack connector into the RJ-45 port. Use

The following figure illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.

Figure 55: RJ-45 Connector

– 89 –

10/100BASE-TX PIN ASSIGNMENTS

Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).

The RJ-45 port on the access point supports automatic MDI/MDI-X operation, so you can use straight-through or crossover cables for all network connections to PCs, switches, or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable.

This product includes copyrighted third-party software subject to the terms of the GNU General Public License (GPL), GNU Lesser General Public License (LGPL), or other related free software licenses. The GPL code used in this product is distributed WITHOUT ANY WARRANTY and is subject to the copyrights of one or more authors. For details, refer to the section "The GNU General Public License" below, or refer to the applicable license as included in the source-code archive.

THE GNU GENERAL PUBLIC LICENSE

GNU GENERAL PUBLIC LICENSE Version 2, June 1991

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

Preamble

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

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

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

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

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.

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

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

| License Information

The GNU General Public License

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

1. This License applies to any program or other work which contains a notice placed by the

copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.

2. You may copy and distribute verbatim copies of the Program's source code as you receive it, in

any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

3. You may modify your copy or copies of the Program or any portion of it, thus forming a work

based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:

a). You must cause the modified files to carry prominent notices stating that you changed the

files and the date of any change.

b). You must cause any work that you distribute or publish, that in whole or in part contains or is

derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.

c). If the modified program normally reads commands interactively when run, you must cause

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

These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.

In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

4. 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,

– 93 –

PPENDIX

| License Information

The GNU General Public License

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.

5. 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.

6. 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.

7. 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.

8. 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 royaltyfree 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.

– 94 –

| License Information

The GNU General Public License

9. 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.

10. 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.

11. If you wish to incorporate parts of the Program into other free programs whose distribution

conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.

NO WARRANTY

1. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY

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

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.
