the Device. In addition, it briefly describes the layout of the Device’s Web interface.
3.1 Configuring Your Computer
To configure the Device via Web UI, you need to properly configure TCP/IP settings on the
computer that you use to manage the Device. To do this, follow these steps:
Step 1 Connect the computer to a LAN port of the Device, or connect the computer
to the Device wirelessly.
Step 2 Install TCP/IP protocol on your computer. If it is already installed, please
skip this step.
Step 3 Configure TCP/IP settings on your computer: set the IP address to an
unused one in the 192.168.1.0/24 subnet, set the subnet mask to
255.255.255.0, and set the default gateway to the IP address of your
gateway. Note: the Device’s default LAN IP address is 192.168.1.253
with a subnet mask of 255.255.255.0.
Step 4 Use the Ping command to verify network connectivity between the
computer and the Device. Open the command prompt on the computer, type
ping 192.168.1.253, and then press Enter. The following uses Windows XP

Chapter 4 Fit AP
In this chapter, we first provide an overview of AP centralized management. Then we describe the
features and parameters supported in Fit AP mode.。
AP Centralized Management Overview
4.1 Terminology
Client: A PC, laptop, or other terminals with a wireless Network Interface Card.
WLAN (Wireless Local Area Network): A WLAN is a type of local area network that uses high
frequency radio waves rather than wires to transmit data.
WAC-1000 / WAC-1001 (Wireless LAn Controller): An WAC-1000 / WAC-1001, also known as
WLAN controller, is a network device that is used to control and manage access points in the
network.
AP (Access Point): An AP is a network device that acts as a base station for the wireless LAN, and
acts as a bridge between wired and wireless networks.
Fat AP: A standalone AP that independently controls and manages wireless clients.
Fit AP: A simple AP that relies on WLAN controller to control and manage wireless clients. The
Device in Fit AP mode can retrieve firmware and configuration file from the WLAN controller.
Intra-Controller Roaming: Intra-controller roaming occurs when a wireless client roams between
APs managed by the same WLAN controller.
Layer 2 Roaming: Layer 2 roaming occurs when a wireless client roams between APs on the
same subnet and VLAN.
4.2 Communication Process
The figure below shows the communication process between a fit AP and WAC-1000 /
WAC-1001.
For the implementation of Fit AP + WAC-1000 / WAC-1001 solution, the first and crucial step is
the issue of Fit AP's registration on the three-layer switch, and the WAC-1000 / WAC-1001 can
manage Fit AP only after Fit AP is successful in registration. In the practical applications, it is
common for WAC-1000 / WAC-1001＋Fit AP to register by crossing three-layer network. Our
18
device has three ways of implementation: the first is the DNS mode, which requires the support
from DNS, DHCP Server, and is relatively complex; the second is the DHCP Option43 attribute
mode, that is, using the Option43 attribute of the DHCP Server; the third is to configure the
WAC-1000 / WAC-1001 address on AP, and this method is relatively simple.
When the wireless controller WAC-1000 / WAC-1001 is connected with the Fit AP by crossing
three-layer network, the Option 43 mode is used; when Fit AP is connected to the wireless
controller by crossing three-layer network, Fit AP can directly obtain the IP address of the wireless
controller through the Option 43 attribute of DHCP, thus completing the registration on the
wireless controller. The specific process is shown in the figure below:
Figure 4-1 WAC-1000 / WAC-1001 and AP centralized manager communicate on the second floor
When the Fit AP and the wireless controller cross three layers of network connection, the
registration procedure of the Fit AP in the wireless controller through the Option 43 attribute of
DHCP server is as follows:
1) Fit AP obtains IP address, option 43 attribute (the attribute carries the IP address of the
three-layer switches) through the DHCP server.
2) Fit AP will obtain the IP address of three-layer switch from the option 43 attribute, and then
sends the unicast discovery request to the wireless controller.
3) The wireless controller of the wireless switch that receives the discovery request packet will
check if the Fit AP has the access to this machine, and answers that it discovers a response if any.
4) Fit AP downloads the latest version of software from wireless controller of the wireless switch.
5) Fit AP downloads the latest configuration from the wireless controller.
19
6) Fit AP begins to work normally to exchange of user data packets with the wireless controller.
Tip:
(1) In the process of device operation, while the configuration file is modified on the AP,
for instance, it joins in a service area, WAC-1000 / WAC-1001 will save the
modified configuration file locally and send it to AP, and the configuration file will
be deleted after WAC-1000 / WAC-1001 powers off.
(2) WAC-1000 / WAC-1001 will delete the configuration file saved before after
recovering the AP to its factory configuration remotely.
(3) The AP uploaded configuration file will not be displayed in the configuration file list.
(4) AP can start transmitting user data immediately after successfully obtaining the
software, configuration file.
4.3 Layer 2 Roaming
Mobility, or roaming, is a wireless client’s ability to move from one AP coverage area to another
without interruption in service or loss in connectivity.
The Device supports layer 2 roaming, which allows wireless clients to roam across access points
on the same subnet and VLAN. To implement layer 2 roaming, you need to assign the same
WLAN profile to the access points, so that they have the same SSID, on the same subnet and the
same VLAN. Figure 4-2 shows intra-controller layer 2 roaming, which occurs when the two APs
are joined.
Figure 4-2 Intra-Controller Layer 2 Roaming
As shown in the above figure, AP1, AP2 are associated with WAC-1000 / WAC-1001.
20
1） A terminal is wirelessly associated with AP1, and AP1 is connected to WAC-1000 /
WAC-1001.
2） The terminal disconnects its association with AP1, and roams into the AP2 connecting the
wireless controller WAC-1000 / WAC-1001.
The process that the terminal is connected to AP2 is referred to as two-layer wireless roaming.
Way of implementation: Configure a service area on the device and enable the two-layer roaming
function by adding AP1, AP2 into the same service area.
4.4 System mode:
The device supports fat AP mode and thin AP mode, and the device's factory default mode of
operation is thin AP mode. If you need to change the working mode of the device, please go to
Start-> System mode Page, or Wireless configuration -> System mode page for modification,
while modifying via AC remotely.
Note: The AP will automatically restarted during switching of modes.
Figure 4-3 Working mode
4.5 Configuration of LAN port
The default IP address of the device LAN port is 192.168.1.253, and the IP address of the device's
LAN port needs to be changed to adapt to the existing network, which can be modified by either
of the following methods.
Method I: Local modification
Enter Network parameters ->LAN port configuration page to configure the LAN port IP
address of the device. The access mode supported by the device LAN port: fixed IP access,
dynamic IP access. These two access modes will be introduced respectively in the subsequent
sections.
Method II: Remotely modification
When the device is connected to AC as a thin AP, the administrator can modify the device's LAN
port IP address on AC through remote management. For configuration details, refer to Item 2.8
21
Advanced Configuration of Wireless Controller.
4.6 Fixed IP access
The default of LAN port access is fixed IP access. The following describes the meaning of the
parameters for configuration of fixed IP access.
Figure 4-4 Fixed IP access
Access mode: Selects fixed IP access here;
IP address: The IP address of device LAN port, through which the administrator can manage
this device;
Subnet mask: It is the subnet mask of device LAN port, which should be consistent with the
subnet mask of the network computer;
Gateway address: The IP address of the device LAN port with the intranet as a gateway;
AC address: Sets the IP address of AC.
Primary/Secondary DNS server: Sets the IP address of the primary/secondary DNS server.
MAC address: It is the MAC address of device LAN port, which needs no change if there are
no special requirements.
4.7 Dynamic IP access
If the IP address of device LAN port is acquired from the DHCP server dynamically, select the
access way of dynamic IP.
22
Figure 4-5 Dynamic IP access
Tip:
1） After the address of the LAN port is modified, please log in the device using the new IP
address of LAN port.
2） When the LAN access mode is dynamic IP access, please confirm the LAN port IP address at
the DHCP server.
4.8 Status of wireless host

6.1 DHCP server settings
The the DHCP server functions on the device are disabled by default.
Figure 6-1 Configuring the DHCP service
Enable DHCP server: Select to enable the device's DHCP server function;
30
Origin and destination address: The IP address fields the DHCP server assigns to the network
computer automatically (which should be on the same network segment as the IP address of
the device LAN port);
Subnet mask: The subnet mask automatically assigned by the DHCP server to the network
computer (which should be consistent with that of the LAN port of the device);
Gateway address: The gateway IP address the DHCP server automatically assigns to the
network computer (which is set to the LAN IP address of the device with Intranet as a
gateway);
Leasing time: The leasing time for the network computers to obtain the IP address assigned
by the device(Unit: Seconds).
Primary DHCP server: The IP address of the primary DNS server assigned by the DHCP
server to the network computers automatically.
Secondary DNS server: The IP address of the secondary DNS server assigned by the DHCP
server to the network computers automatically.
Tip:
1. If the device's DHCP server function is to be used, network computer's TCP/IP protocol can
be set to "obtain an IP address automatically".
2. In the case where the Intranet already has a DHCP server, it is not recommended to enable the
DHCP server function of the device.
6.2 Static DHCP
This section describes the static DHCP list and the way to configure a static DHCP.
Using the DHCP service to automatically configure TCP/IP properties for the network computers
is very convenient, but it can cause a computer to be assigned with different IP address at different
times. And some Intranet computers may need a fixed IP address, in this case, the static DHCP
function is required, to bind the computer's MAC address with an IP address, as shown in Figure
6-2. When a computer having this MAC address requests the address from the DHCP server
(device) , the device will find a corresponding fixed IP address based on its MAC address and
assign it to the computer.

Wireless basic configuration
This section describes the Wireless Configuration -> Wireless basic configuration page and the
configuration methods. In this page, you can configure the AP work mode, SSID, wireless mode,
channel, channel bandwidth, enabling or disabling the SSID broadcast and other functions of the
device. IN This section, the AP working mode is used: The wireless basic configuration is
introduced in the order of AP Mode and WDS.
WDS (Wireless Distribution System) wireless distributed system, is a protocol for two access
points (AP) in wireless connection. Throughout the WDS wireless network, multiple APs are
connected by the way of bridging or repeater, make the entire LAN be dominated by wireless
mode.
The WDS configuration provided by the device consists of three modes: Bridge Mode, Repeater
Mode and Lazy Mode, which only plays a bridging function only in the practical application, and
in configuration, the LAN IP of the device must be in the same network segment, while the
parameters for security mode and channel bandwidth for connecting with each other must be
consistent.
35
7.1 AP Mode
Figure 7-1 AP Mode
Enable wireless function: Only after the wireless function is enabled can the wireless clients
be connected to the device, to have wireless communications through the device, connect and
access the cable network to which the device is connected;
AP work mode: Selecting the AP Mode, namely the pure AP mode, in which the peer device
can be a single cli ent;
SSID (Service Set Identification) is used to uniquely identify a character string of wireless
network, and is case sensitive.
Wireless mode: This parameter is used to set the modes of the wireless device, to providing
four options: only 11g, only 11n, 11b/g/n hybrid and 11g/n hybrid:
Only 11g: pure 802.11g mode, in which the maximum rate is up to 54M bps. The
wireless sites compatible with the IEEE 802.11g standard can be connected to the
device;
Only 11n: pure 802.11n mode, in which the maximum rate is up to 300M bps. The
wireless sites compatible with the IEEE 802.11n standard can be connected to the
device;
11b/g/n hybrid: The wireless sites in compliance with IEEE 802.11b, 802.11g or
802.11n standard will be connected according to their modes, with the maximum rates
of 11M bps, 54M bps and 300M bps respectively;
11g/n hybrid: The wireless sites in compliance with IEEE 802.11g or 802.11n standard
36
will be connected according to their modes, with the maximum rates of 54M bps and
300M bps respectively;
Channel: This parameter is used to select the frequency bands in which the wireless network
works, with the available range from 1 to 13, and it provides automatic options, which means
that the device can automatically select the optimal frequency band. If there is more than one
wireless device, the settings of frequency band of the devices cannot affect each other;
Channel bandwidth: The channel bandwidth occupied by the wireless data transmission, with
the options: 20M/40M 和20M. Note that this parameter works only with the wireless site
accessed using the 802.11n standard; for those using the 802.11b or 802.11g standard, only
the channel bandwidth of 20M can be used:
20M/40M: When 20M/40M is selected, it means the wireless sites accessed using
the 802.11n standard will use the channel bandwidths of 20M or 40M according to
the results of the negotiation with the accessed peer end;
20M: When 20M is selected, it means the wireless sites accessed by using the
802.11g standard will use the channel bandwidth of 20M.
SSID broadcast: Enables or disables the SSID broadcast function. If this function is enabled,
the device will broadcast its own SSID to all the wireless sites so that the wireless sites
without SSID (null) will get the correct SSID, to be able to connect to the device, and join
into the wireless network with this SSID identifier. This function is enabled at risk (illegal
sites are very easy to get the SSID information), so it is generally recommended to disable
this function.
Tip:

Wireless Advanced Configuration
This section describes the meaning of the wireless advanced parameters in the Wireless
Configuration-> Wireless advanced configuration.
In this page, you can set wireless advanced parameters, and under normal circumstances, keep the
default values of these parameters. If you have special needs, you can configure in this page.
Figure 7-15 Wireless Advanced Configuration
RTS threshold: When a packet exceeds this threshold, it will activate the RTS mechanism.
Before transmitting data frames, the device will send RTS (Request to Send) packet to the
destination site for negotiation; after receiving an RTS frame, the wireless site will respond to
the device by sending a CTS (Clear to Send) frame, which means wireless communication
can be made between both of them. Value range is generally 1~2347 bytes, and the default is
2347 bytes;
The RTS mechanism is used to avoid data transmission conflicts in the wireless LAN. The
transmission frequency of the RTS packet needs to be set reasonably, and setting of the RTS
threshold requires weighing. If this parameter is set to low, the transmission rate of RTS
packets is increased, consuming more bandwidths, which may significantly affect the
throughput of other network packets. But the more frequently the RTS packet is sent, the
more quickly the system can recover from disruption or conflict;
Segmentation threshold: It is used to define the maximum transmission length of the wireless
data packets allowed by the wireless MAC layer to be transmitted, when the length of Data
frames exceeds this value, they will automatically be segmented into multiple data frames,
and then transmitted again. If the segmented transmission is interrupted, only the parts that
are not sent successfully need to be sent, and the throughput of segmented packets is
generally low. Value range is generally 256~2346 bytes, and the default is 2346 bytes.
49
The transmission efficiency for large segments is high, but if there is a clear conflict in the
wireless network, or if the network is used at a high frequency, the reduction of segments can
improve the reliability of data transfer. In most cases, keep the default value as 2346;
Beacon interval: The device synchronizes the wireless network connection through regular
Radio Beacon frames. This parameter is used to define the transmission interval of beacon
frames which are transmitted periodically at the specified time interval. Value range is
generally 20~999 ms, and the default is 100 ms.
DTIM interval: This parameter is used to specify the transmission interval for the Delivery
Traffic Indication Message (DTIM). DTIM interval is used to decide the frequency of beacon
frames containing Traffic Indication Map (TIM) to be transmitted. TIM will issue a warning
to the sites entering into the sleep status, by indicating that the data is to be received. DTIM is
usually the multiple of beacon interval. Its use range is 1~255, and its default value is 1;
Enable Short Preamble: Enables or disables Short Preamble.
When enabled, the short preamble type will be used; the short preamble type can
provide better performance. Because the use of short preamble can minimize costs,
thus maximizing the network data throughput;
When disabled, the long preamble type (Long Preamble) will be used; the long
preamble type will be able to provide more viable connections and a large range of
connections;
Enable WMM: Allows you to enable or disable the WMM support. WMM (Wi-Fi
Multimedia) is a subset of the 802.11e standard. WMM allows wireless traffic to have a
priority range based on the data type. Time-sensitive information, such as video or audio, will
have a higher priority than the normal traffic. To use the WMM function properly, wireless
clients must also support WMM.
Status of wireless host
This section describes the Wireless Configuration -> Wireless host status page. Through the
"List of the wireless host status information", you can view the status information of the wireless
hosts currently connected to the device. In addition, through the "List of the wireless host status

Chapter 8 System management
In the System Management main menu, you can enter the Administrator configure, clock
management, configuration management, software upgrade, and scheduled task pages. This
chapter mainly describes how users set the device clock; how to back up and import the
configuration files; how to upgrade device, etc.
8.1 Administrator configuration
Enter into the System Management-> Administrator configuration page, to view and configure
the device administrator's user name and password.

User name: Customize the user name of the administrator who logs in the WEB interface;
Password, confirm password: Customize the password of the administrator who logs in the
WEB interface;
3) Modification of administrators' factory user name, password
For security reasons, we strongly recommend to modify the initial administrator user name and
password, and to keep them with care.
Enter into the System Management-> Administrator configuration page, click on the Edit icon
with the user name as "admin", enter into the configuration page to modify the factory user name
and password. After modification, you must use the new user name and password to log into the
device.
8.2 Clock management
This section describes the System Management-> Clock management page.
In order to guarantee that the functions of the device relating to time work normally, the clock of
the device needs to be accurately set, to make it synchronize with the local standard time.
The device provides two ways of setting system time, "Manual setup time" and "Network time
synchronization". It is recommended to use the "Network time synchronization" function to obtain
the standard time, and the device will automatically get the standard time from the Internet after it
connects Internet in bootup.
Figure 8-3 Clock management
53
Current system time: Displays the current date and time information of the device (unit:
Y-M-D, H:M:S).
Time zone selection: Selects the international time zone in which the device resides. Only
choosing a correct time zone can the network time synchronization function work properly.
Manual time setting: Manually enters the current date and time (unit: Y-M-D, H:M:S);
Network time synchronization: After using the network time synchronization function to set
up the right NTP server, and when the device is connected to the Internet, it will
automatically synchronize the time with the set NTP server. The addresses of two NTP
servers preset by the system by default are 192.43.244.18, 129.6.15.28, which generally
requires no change. If you need to know more about the NTP knowledge and the server, just
visit http://www.ntp.org.
8.3 Configuration management
This section describes the configuration methods of System management -> Configuration
management. In this page, you can back up the current configuration file to a local PC, import the
new configuration file to the device and restore the factory configuration of the device.
Figure 8-4 Configuration management
1) Backup configuration files
Click on the <Save> button in the above figure, to back up the configuration file to the local PC,
with the format of the configuration file as .xml.
2) Import configuration file
In the previous figure, click < Browse ... >, and select the configuration file saved on the local PC.
Then click <Import> again. If you have checked the check box "Restore factory configuration
before import", click the <Import> button, and the device will be restore to the factory settings.
54
3) Restore to factory settings of device
If users need to restore the device to its factory settings, enter into the Systems management ->
Configuration management page, and click <Restore>.
Tip:
1） Do not cut off the device power supply in loading configuration, in order to avoid unexpected
errors.
2） Restoring the device's factory settings will delete all the custom settings. It is strongly
recommended that before restoring the factory configuration, first back up its configuration
files.
3） The user name and password of the device's factory administrator are as follows: admin, and
the default LAN port IP address/subnet mask is: 192.168.1.253/ 255.255.255.0.
4） After clicking <Restore>, the device needs to be rebooted before restoring its factory settings.
8.4 Software upgrade
This section describes the System management-> Software upgrade page and the software
upgrade procedure. In this page, you can view the information of the currently running version,
and download the latest software from the LevelOne web site.

2) It is recommended that before upgrading, enter into Systems management -> Configuration
management to back up the current configuration of the system.
3) It is strongly recommended to upgrade when the device load is low (less users).
4) Upgrading device software on a regular basis enables the device to get more functions or to
have a better working performance. The right software upgrading will not change the current
device settings.
5) During the upgrading process, the device's power supply cannot be cut off, otherwise it will
cause unpredictable errors and even irreversible damages to the hardware.
6) After the completion of upgrading, the software will automatically restart to take effect,
without the need of human intervention.
8.5 Scheduled task
This section describes the System management-> Scheduled task page. By configuring
scheduled tasks, administrators can predefine the actions completed by the device at a specified
time.
1) List of scheduled tasks
The scheduled task list is an editable list. You can operate the instances in the list.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301,
USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away
your freedom to share and change it. By contrast, the GNU
65
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 Lesser 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.
66
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 Progra m" 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
67
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.
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 c ommands
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
68
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:
we use this doubled UL to get the sub-sections indented,
while making the bullets as unobvious as possible.
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
69
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.
70
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 r oyalty-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.
71
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.
72
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

How to Apply These Terms to Your
New Programs
If you develop a new program, and you want it to be of the
greatest possible use to the public, the best way to achieve
this is to make it free software which everyone can
redistribute and change under these terms.
To do so, attach the following notices to the program. It is
safest to attach them to the start of each source file to most
effectively convey the exclusion of warranty; and each file
should have at least the "copyright" line and a pointer to
where the full notice is found.
one line to give the program's name and an idea of what it
does.

Also add information on how to contact you by electronic and
paper mail.
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
to redistribute it under certain conditions; type `show c'
for details.
The hypothetical commands `show w' and `show c' should
show the appropriate parts of the General Public License. Of
course, 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:
Yoyodyne, Inc., hereby disclaims all copyright
interest in the program `Gnomovision'

by James Hacker.

This General Public License does not permit incorporating
your program into proprietary programs. If your program is a
subroutine library, you may consider it more useful to permit
linking proprietary applications with the library. If this is what
you want to do, use the GNU Lesser General Public License
instead of this License.
