Setup Wizard
Step1. “LAN Setup” is shown in the diagram.
Each setup item of the local area
network is default setting, and is not necessary to make change to it for normal
operation. Please input the settings on your own if change is needed.
DHCP Setup:
- ”enable” indicates that the DHCP function of the GN-BR404W is initialized,
and you configure the computers on your network to “Obtain an IP address
automatically”, then when you turn your computer “On”, it will automatically
load the proper TCP/IP setting from GN-BR404W. (Configure the DHCP
starting address and the DHCP allocation number on your own.)
- “disable” indicates that it will not automatically load proper TCP/IP setting
from the GN-BR404W. You will have to configure all the TCP/IP setting for
your network manually. (It is not necessary to configure the DHCP starting
address and the DHCP allocation number.)
DHCP Start Address / End Address :
When the DHCP setting is “enable”, the GN-BR404W uses this allocable
range of the IP address as the initial value to assign the IP to the PC connected
to the LAN end.
For example:
The DHCP start address is 192.168.1.1 and the end address is 192.168.1.50 .
The IP allocable range of the DHCP is from 192.168.1.1 to 192.168.1.50.
The LAN IP address “192.168.1.254” is the default IP address of the
GN-BR404W.

Those information are provided by your ISP company.
• MTU(Maximum Transmission Unit)
This defines the maximum size of the packets sent from your computer onto the
network. Any messages larger than the MTU are divided into smaller packets
before being sent. Leave this on the default value(1500) unless you have a
particular reason to change it.
• NAT Setup
The Internet is expanding at an exponential rate. As the amount of information and
resources increases, it is becoming a requirement for even the smallest
businesses and homes to connect to the Internet. Network Address Translation
(NAT) is a method of connecting multiple computers to the Internet (or any other IP
network) using one IP address. This allows home users and small businesses to
connect their network to the Internet cheaply and efficiently.
Universal Plug and Play (UPnP) is an architecture for pervasive peer-to-peer
network connectivity of PCs and intelligent devices or appliances, particularly
within the home. UPnP builds on Internet standards and technologies, such as
TCP/IP, HTTP, and XML, to enable these devices to automatically connect with
one another and work together to make networking - particularly home networking

- possible for more people.
Normal user please select “NAT enable” or “UPnP&NAT” then connect to the
Internet in general.
• UPnP Delete Time
This variable determines the time to live in hours of a port-mapping lease when the
value of Lease Time is 0.
Note: If the WAN IP address which got form a DHCP server and the LAN IP address
are on the same subnet, the LAN IP address will be changed to another subnet
automatically and reboot the device.
Verify the desired setting and then click the “Finish” button to set the value into
GN-BR404W.

• Authentication Type
You may choose between “Auto”, “CHAP” and “PAP”. The default is set to “Auto”.
Challenge Handshake Authentication Protocol(CHAP). This is the preferred
method of authentication for PPP dialup links. With CHAP, the server sends a
challenge to which the remote router sends an encrypted reply containing a secret
key.
Password Authentication Protocol(PAP) is a simple authentication protocol for PPP
allowing a router to identify itself with another router by sending a simple name and
password combination. PAP is defined in RFC1334.
• Connection
“Automatic” It connects to an ISP without delay when the router is turned on. If
connection is disconnected by something troubles, connection have
to retry to connect automatically.
“Manual”
It connects to an ISP when user presses the “connection” button. If
connection is disconnected by something troubles, connection have
to stop.

ꢂ
Multisession Configuration
The Multisession configuration allows you to setup the priority of WAN connection after
you complete the WAN configuration. In our PPPoE multi-session, three connections
will be established in three visual interfaces. Each interface owns ip address, gateway
and netmask belong each sub network. So we can use a set of rule to routing packet.
Which packets all information is matched of rules, it will be routing to different gateway.
On the PPPoE connection when established one connection peer to peer is call
session. If we have multi PPPoE connect at the same time. We must have way to
manager each session.
• Backup Session
User can set the alternate session to the main session as the backup session.
In addition, if main session is fail to connection a backup session is replace main
session.
For example,
The main session could not connect to an ISP.
Further the backup session could not connect too, the main session
Automatic : main -> backup->main->backup…….
Manual : main->backup (Backup tries to connect once only.)
Session keep alive was no response after the main session connected. Sub1 or

Sub2 session have no backup sessions. Backup session can be set the main
session only.
Note: The backup session can be specified LAN type connection.
• Our priority of rule
SUB2 > SUB1 >MAIN
In other words, every packets pass thought the router would be matching SUB2
rule first. If it is match, packet next hop will be change to SUB2 session gateway. If
it is not, the Router check packet information matched with SUB1 rule. If it still not
matched that will be route to main session gateway.
Note:
1. Rule could be overlap for any condition.
2. All of rule in one session must be match.
3. Check order is SUB2->SUB1->MAIN, if any session rules matched. It will
jump out the check order.
4. Main session is default session. All of packets match fail will be group under
main session.
Exception:
1. If sub session connection fail, the rule also to break down. Another session
route path is alive. Packet will pass thought this session. It seems backup the
sub session use main or sub1.
2. If main session is unlink or connection fail, sub1 and sub2 still by pass the
match packet.
3. Each session are independent with NAT address translation.

• RF Type
The option of the RF type is depend on your WLAN Card. If your WLAN Card
supports the network standards of IEEE 802.11b and 802.11g, then the option will
have two setting you can select.
• Channel
Please choose the channel, which you can get best performance. Normally, it
doesn’t need to change. The default value is channel 6.

• SSID
The SSID is the name represent the router in the wireless network. This SSID
string is case sinsitive of up to 32 ASCII characters. The default value is
“GIGABYTE”, if the setup value is the default value, like “router”. Only can accept
the computer connection, which use the wireless card SSID (or ESSID) set up, is
“router”.
• Rate
You can select one of the rates among 1M, 2M, 5.5M and 11M based on your need.
The default value is “auto/best”.
• Hidden SSID
This setting allows you to hide the SSID in wireless transmission. Those who don’t
know the SSID will be able connect to the router. The default value is “disable”.
• Authentication Type
You may choose between “Open System”, “Shared Key”, “WPA Radius with
802.1x” and “WPA Pre-shared key”. The Authentication Type default is set to
“Open System”.
Open System, in which the sender and the recipient do NOT share a secret key.
Each party generates its own key-pair and asks the receiver to accept the
randomly generated key. Once accepted, this key is used for a short time only.
Then a new key is generated and agreed upon.
Shared Key is both the sender and the recipient share a secret key.
If the “Shared Key” option is selected, and then the option “disable” of the WEP
will be disabled.
WPA adius with 802.1x, if you have been using Wi-Fi for a while, you are probably
familiar with the 802.1X authentication protocol. This protocol allows users to
authenticate into a wireless network by means of a RADIUS Server. In standard
Wi-Fi, 802.1X authentication is optional. However, 802.1X authentication is a
requirement for WPA. If your environment does not have a RADIUS server in place,
you can still use WPA in spite of the 802.1X requirement. As an alternative to
RADIUS, WPA supports the use of a preshared key.

WPA Pre-shared key, One of the biggest drawbacks to traditional WEP security is
that changing the encryption key is optional. Even if you do switch encryption keys
from time to time, there is no option for globally rekeying all access points and all
wireless NICs.
Instead, rekeying is a tedious manual process and is completely impractical for
large organizations. After all, the instant you rekey an access point, none of the
clients will be able to access it until they are also rekeyed.
But with WPA, the rekeying of global encryption keys is required. In the case of
unicast traffic, the encryption key is changed after every frame using Temporary
Key Integrity Protocol (TKIP). This protocol allows key changes to occur on a
frame by frame basis and to be automatically synchronized between the access
point and the wireless client. Global rekeying works by advertising the new keys to
wireless clients.
The TKIP is really the heart and soul of WPA security. TKIP replaces WEP
encryption. And although WEP is optional in standard Wi-Fi, TKIP is required in
WPA. The TKIP encryption algorithm is stronger than the one used by WEP but
works by using the same hardware-based calculation mechanisms WEP uses.
The TKIP protocol actually has several functions. First, it determines which
encryption keys will be used and then verifies the client's security configuration.
Second, it is responsible for changing the unicast encryption key for each frame.
Finally, TKIP sets a unique starting key for each authenticated client that is using a
preshared key.
• WEP Key
Protects your information with the highest level of industry-standard WEP
encryption: 64/128/152-bit for 802.11b standard, and up to 152-bit for 802.11g
standards. When the “Disable” is selected there is no WEP encryption. When
“64bits”, “128bits” or “152bits” selected there is encrypted date transfer to prevent
unauthorized user to access the wireless network.
There are three levels of encryption 64 bits, 128 bits and 152bits. The 64 bits
encryption is referenced as a lower level encryption. The 152 bits encryption is
referenced as a higher level encryption.
The 64 bits WEP encryption use 40 bits as a secret key, which can controlled by
user, and 24 bits as the initialize vector, which user can not control. These two
portions plus together is 64 bits encryption. Some other vendor’s product might
refer as 40 bits encryption. It is the same thing.

The 128 bits WEP encryption use 104 bits as a secret key, which can controlled by
user, and 24 bits as the initialize vector, which user can not control. These two
portions plus together is 128 bits encryption. Some other vendor’s product might
refer as 104 bits encryption. It is the same thing.
The 152 bits WEP encryption use 128 bits as a secret key, which can controlled by
user, and 24 bits as the initialize vector, which user can not control. The 152 bits
WEP encryption spawns a KEY ID containing 32 HEX digits.

802.1x
802.1x authentication for wireless LANs provides centralized, server-based
athentication of end users.
1) A client sends a “start” message to a router, which requests the identity of the
client.
2) The client replies with a response packet containing an identity, and the router
forwards the packet to an authentication server.
3) The authentication server sends an “accept” packet to the router.
4) The router places the client port in authorized state, and traffic is allowed to
proceed.

WDS
Wiring is headache and complex problem on the Networking environment all the time.
The Wireless Access Point solves the connection problem between end-users and the
backbone of the network. But it still is requiring establishing a wired backbone network
on this framework.
Wireless Distribution System (WDS), the technology provide a method that use
“Wireless” to take place of the wired backbone networking, allows several of the
access points to compose a wide Wireless LAN network. However, even if the general
business or home use, the access point with WDS function has decreased the
difficultly of the wired wiring. On the real network environment, it is still need to use
wired method to connect router and access point when they want to link ISP to
Internet.
In order to built an entire wireless solution to get rid of the wiring problem. Integrate the
technology of the WDS and Routers that connect the routers and access points
through the WDS has created the concept of the Wireless Distribution.
Advantage:
1. Convenience Environment: It gets rid of the wiring problem and allows all devices
to connect through the Wireless LAN except the connection between the ISP and
routers on the networking environment.
2. Strong expansibility: It can expand the network just add new access point directly
where needs to have the network.

RIP Configuration
RIP(Routing Information Protocol) is a dynamic internetwork routing protocol primary
used in interior routing environments. A dynamic routing protocol, as opposed to a
static routing protocol, automatically discovers routes and builds routing tables.
Static Routing Table
Under some of Internet environments, some of the subnet do not go through the
default gateway. Users can add those routing information to Static Routing Table
themselves.
• Destination IP
The Destination IP address is the address of the network or host to which the
static route is assigned.
• Netmask
The Netmask determines which portion of a destination LAN IP address is the
network portion, and which portion is the host portion.

• Gateway
This is the IP address of the gateway device that allows for contact between the
router and the network or host.
• Metric
Type a numeber between 1 and 15 as the Metric value. This represents the
number of routers between your network and the destination. Usually, a setting of
2 or 3 works, but if this is a direct connection, set is to 1. The default value is 1.

3-4-4. Virtual Server
Virtual server setting split into two different case. Case 1 is router having only 1 global IP
address, PPPoE/DHCP/Static is this case. Case 2 is router having more than 1 global IP
address, normal having 8 or 16 IP address, PPPoE unnumbered is this case. In case 1,
virtual server only need to configure LAN host information, because WAN IP address
always the same, but in case 2, virtual server also need to configure which WAN IP address
need redirect to internal LAN host.

DMZ Support of the Virtual Server
If you have a computer that cannot run an Internet application (e.g. internet game,
vedio conferencing, or VPN connections) properly from behind the NAT firewall, or set
up a server which can connect to the Internet in the Intranet then you can open the
computer up to unrestricted two-way Internet access.To use the DMZ, you have to set
a static IP address for the computer. The IP Address (such as 192.168.1.2) of the
computer at the LAN terminal can be used to input to the field of LAN IP Address.

VPN Pass Through
Virtual private networks (VPN)are secured private network connections, built on top of
publicly-accessible infrastructure, such as the Internet or the public telephone network.
VPNs typically employ some combination of encryption, digital certificates, strong user
authentication and access control to provide security to the traffic they carry. They
usually provide connectivity to many machines behind a gateway or firewall.
GN-BR404W supports Internet-industry standards technology to provide customers
with open interoperable VPN solutions such as Internet Protocol Security (IPSec) and
Layer 2 Tunneling Protocol (L2TP) as well as Point-to-Point Tunneling Protocol
(PPTP).
• PPTP Pass Through setting
PPTP stands for Point-to-Point Tunneling Protocol. It basically allows you to
establish a connection to a corporate network and you can share files and other
data as if your machine were actually on that local network.
• IPSec Pass Through setting
IPSec stands for IP Security. It provides authentication and encryption over the
Internet. It functions at Layer 3 and thus secures everything on the network. It has
become a standard protocol used for virtual private networks (VPNs).

• L2TP Pass Through setting
L2TP stands for Layer 2 Tunneling Protocol. It is an extension of the Point-to-Point
Tunneling Protocol and is also used to establish virtual private networks.
Enable/Disable VPN pass through. If administrator configure a host to enable VPN
pass through, router will automatically setting virtual server and firewall setting for this
host. All VPN packets will be transparent and will redirect to this host. VPN pass
through works, either VPN server behind the LAN side or VPN server locate at WAN
side. For different VPN pass through setting, only 1 host can be configured as pass
through.

3-4-6. DNS Configuration
ꢂ
ꢂ
DNS Replay
The default value of the DNS replay is “Enable”. The DNS query packets will send
through the router. When a DNS query packet enters the router, and the router will
sends an answer to the host that sent the DNS query packet. And then users have to
set the IP address of the router as the IP address of the DNS.
Dynamic DNS
The Router offers a Dynamic Domain Name Server service. The Dynamic DNS allows
you to assign a fixed host and domain name to a dynamic Internet IP address. It is very
useful when combined with the “Virtual Servers” feature. It allows Internet users to
contact to your virtual severs using a URL, rather than an IP address. Before you to
use this feature, please register for an account with one of the dynamic DNS service at
1. You can Disable or Enable the Dynamic DNS service.
2. Select the name of your dynamic DNS service provider.
3. Type the Domain Name(or Host Name) that your dynamic DNS provider gave you.
4. Type the login Name(or Username) and Password for your dynamic DNS account.
5. If your dynamic DNS provider allows the use of wildcards in resolving your URL,
you may select the Enable wildcard to active this function.

3-4-8 VPN Configuration
A VPN is a secure, private communication tunnel between two or more devices across a
public network (like the Internet). These VPN devices can be either a computer running
VPN software or a special device like a VPN enabled router. It allows your home computer
to be connected to your office network or can allow two home computers in different
locations to connect to each over the Internet.
Clients and Servers
A VPN server is a piece of hardware or software that can acts as a gateway into a whole
network or a single computer. It is generally ‘always on’ and listening for VPN clients to
connect to it.
A VPN Client is most often a piece of software but can be hardware too. A client initiates a
‘call’ to the server and logs on. Then the client computer can server network can
communicate. They are on the same ‘virtual’ network. Many broadband routers can 'pass'
one or more VPN sessions from your LAN to the Internet. Each router handles this
differently.
The Gigabyte router is a IPSec VPN which support following function:
1. Groups for Diffie-Hellman key negotiation - group 2, modp 1024-bit
2. Encryption transforms - Triple DES
3. Authentication transforms -HMAC using MD5

4. Troubleshooting
This chapter gives information about troubleshooting your wireless broadband router. Read
the descriptions below to help you diagnose and solve the problem.
Q: What to do if you forget your password or forget the IP address of the router?
A: Please press the “init” bottom on the router. The router will be restart and the system
setting will restore to the default value.
Q: Unable to connect to the Internet?
A: 1. Please confirm whether or not the power cord is connected properly, and the
power indicating light of the router is normal.
2. Please confirm whether or not all of the settings described in this manual are
set.
3. Please confirm if ADSL or Cable Modem operates properly, and if the ISP
network service expires.
4. Please confirm if your network cable is connected properly, and the LED status
is normal.
Q: What is the IEEE802.11b standard?
A: It also referred to as 802.11 High Rate or Wi-Fi. It is an extension to 802.11 that
applies to wireless LANS and provides 11 Mbps transmission (with a fallback to 5.5,
2 and 1 Mbps) in the 2.4 GHz band. 802.11b uses only DSSS. 802.11b was a 1999
ratification to the original 802.11 standard, allowing wireless functionality
comparable to Ethernet.
Q: Unable to access the router’s Web Configuration Interface?
A: 1. Please check the Ethernet connection between the PC and the router is
correctness.
2. Make sure your computer’s IP address is on the same subnet as the router.
3. Make sure you are using the correct login information.
Q: Where is the router installed on the network?
A: In a typical environment, the router is installed between the ADSL or Cable Modem
and the LAN. Plug the router into the Ethernet port of the ADSL or Cable Modem.

Q: Can the router act as DHCP server?
A: Yes. The router has the DHCP server function built-in.
Q: What is WEP?
A: Wired Equivalent Privacy. Security mechanism defined within the 802.11 standard
designed to make the link integrity of the wireless medium equal to wired cable. Data
privacy mechanism based on a 40 bits (128 bit optional ) shared key algorithm, as
described in the IEEE 802.11 standard.
Q: What is the IEEE802.11g standard?
A: IEEE 802.11g standard specifies data rates of up to 54 Mbits/s in the 2.45-GHz
band. It uses orthogonal frequency division multiplexing (OFDM), mandatory
provisions have been made within the standard to make it inherently compatible with
the well-established 802.11b standard at 11 Mbits/s, which uses complementary code
keying (CCK) modulation. Both .11g and .11b operate at ranges of up to 300 feet.

Appendix A: Glossary
ADSL
Asymmetric digital subscriber line (ADSL) is a new modem technology that converts
existing twisted-pair telephone lines into access paths for high-speed communications of
various sorts.
Auto-MDI/MDIX
On a network hub or switch, an auto-MDI/MDIX port automatically senses if it needs to act
as a MDI or MDIX port. The auto-MDI/MDIX capability eliminates the need for crossover
cables.
Auto-negotiate
To automatically determine the correct settings. The term is often used with
communications and networking.
DHCP
The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for automating the
configuration of computers that use TCP/IP. DHCP can be used to automatically assign IP
addresses, to deliver TCP/IP stack configuration parameters such as the subnet mask and
default router, and to provide other configuration information such as the addresses for
printer, time and news servers.
DMZ
In computer networks, a DMZ (demilitarized zone) is a computer host or small network
inserted as a "neutral zone" between a company's private network and the outside public
network. It prevents outside users from getting direct access to a server that has company
data. Typically, the DMZ contains devices accessible to Internet traffic, such as Web (HTTP )
servers, FTP servers, SMTP (e-mail) servers and DNS servers.
DNS
The Domain Name System (DNS) is a distributed Internet directory service. DNS is used
mostly to translate between domain names and IP addresses, and to control Internet email
delivery. Most Internet services rely on DNS to work, and if DNS fails, web sites cannot be
located and email delivery stalls.

Dynamic IP Address
An IP address that is automatically assigned to a client station in a TCP/IP network,
typically by a DHCP server.
Firewall
A system designed to prevent unauthorized access to or from a private network. Firewalls
can be implemented in both hardware and software, or a combination of both. Firewalls are
frequently used to prevent unauthorized Internet users from accessing private networks
connected to the Internet, especially intranets. All messages entering or leaving the intranet
pass through the firewall, which examines each message and blocks those that do not
meet the specified security criteria.
Gateway
A device, usually a router, that connects hosts on a local network to other networks.
IP Address
Every machine on the Internet has a unique identifying number, called an IP Address. A
typical IP address looks like this: 216.27.61.137
IPSec
IPSec stands for IP Security. It provides authentication and encryption over the Internet. It
functions at Layer 3 and thus secures everything on the network. It has become a standard
protocol used for virtual private networks (VPNs).
MAC Address
On a local area network (LAN) or other network, the MAC (Media Access Control) address
is your computer's unique hardware number. Usually written in the form 01:23:45:67:89:ab
MTU
The size in bytes of the largest packet that can be sent or received.
NAT
A technique by which several hosts share a single IP addree for access to the Internet.
Ping (Packet Internet Groper)
A utility to determine whether a specific IP address is accessible. It works by sending a
packet to the specified address and waiting for a reply. PING is used primarily to
troubleshoot Internet connections.

SSID
The SSID is the name represent the router in the wireless network.
PPPoE
Point-to-Point over Ethernet is a protocol for connecting remote hosts to the Internet over
an always-on connection by simulating a dial-up connection.
Router
A device that forwards data packets along networks. A router is connected to at least two
networks, commonly two LANs or WANs or a LAN and its ISP network. Routers are located
at gateways, the places where two or more networks connect.
Subnet Mask
A mask used to determine what subnet an IP address belongs to. An IP address has two
components, the network address and the host address. Subnetting enables the network
administrator to further divide the host part of the address into two or more subnets.
TCP/IP
TCP/IP (Transmission Control Protocol/Internet Protocol), the suite of communications
protocols used to connect hosts on the Internet.
VPN
Virtual private networks are secured private network connections, built on top of
publicly-accessible infrastructure, such as the Internet or the public telephone network.
VPNs typically employ some combination of encryption, digital certificates, strong user
authentication and access control to provide security to the traffic they carry. They usually
provide connectivity to many machines behind a gateway or firewall.
WAN
Wide Area Network, a communication network that covers a relatively large geographic
area, consisting of two or more LANs. Broadband communication over the WAN is often
through public networks such as the ADSL or Cable systems, or through leased lines or
satellites. In its most basic definition, the Internet could be considered a WAN.
WEP
WEP (Wired Equivalent Privacy) is a data privacy mechanism based on a 64/128-bit shared
key algorithm, as described in the IEEE 802.11 standard.

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 redistributors of a free program will individually
obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free
use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
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:
101
Download from Www.Somanuals.com. All Manuals Search And Download.
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.
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 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 conditions for copying, distributing or modifying the
Program or works based on it.
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 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.
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 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.
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 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.
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.

If the program is interactive, make it output a short notice like this when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
type `show w'. This is free software, and you are welcome

for details.
The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be
called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is
a sample; alter the names:
