<h2><a name="news">News</a></h2>
<div class="news-date">Fri Oct 17 2003: </div> <p class="news-text"><a
href="@PACKAGE_URL@waproamd-0.3b.tar.gz">Version 0.3b</a> released,
changes include: minor bug fixes.</p>
<div class="news-date">Fri Oct 17 2003: </div> <p class="news-text"><a
href="@PACKAGE_URL@waproamd-0.3.tar.gz">Version 0.3</a> released,
changes include: split <tt><a href="http://0pointer.de/lennart/projects/aeswepd/"><tt>aeswepd</tt></a></tt> into its
own package, add documentation, several bug fixes.</p>
<h2><a name="overview">Overview</a></h2>
<p><tt>waproamd</tt> is a roaming daemon for wireless IEEE 802.11 NICs supporting the
Linux wireless extensions. It is intended to configure the WEP
keys according to the networks found.</p>
<p><tt>waproamd</tt> is intended to be used together with <a href="http://0pointer.de/lennart/projects/ifplugd/"><tt>ifplugd</tt></a>. Whenever
an association succeeds, <tt>ifplugd</tt> detects it and runs further
configuration commands for it.</p>
<h2><a name="status">Status</a></h2>
<p>Version 0.3 works fine on <a href="http://www.hostap.org"><tt>hostap</tt></a> 0.0.4 and <tt>airolan</tt>. Other driver/card combinations not tested, but may work too.</p>
<h2><a name="documentation">Documentation</a></h2>
<p>Have a look on the man pages <a href="@PACKAGE_URL@waproamd.8.xml"><tt>waproamd(8)</tt></a>, <a href="@PACKAGE_URL@waproamd.conf.5.xml"><tt>waproamd.conf(5)</tt></a>. (An XSLT capable browser is required)</p>
<h3>Mode of Operation</h3>
<p>As long as the local NIC is not associated to any wireless
network <tt>waproamd</tt> scans iteratively for them. If one is detected, a
script in <tt>@sysconfdir@/waproamd/scripts/</tt> named after
the MAC address of the access point is called. If this script is
not existent, <tt>@sysconfdir@/waproamd/scripts/default</tt>
is called instead. The first argument to this script is
<tt>"start"</tt>. If the association is lost, the same script is run with
the argument <tt>"stop"</tt>. While the NIC is associated no scans are
issued.</p>
<p>If multiple WLANs are detected at the same time, the network
which is detected by the hardware first is selected. However,
networks where a matching script exists take precedence.</p>
<p><tt>waproamd</tt> requires a network driver supporting the Linux
wireless extensions v15 or newer. The driver needs to support scanning
for wireless networks, which may be tested by running <tt>"iwlist
scan"</tt>. If the driver supports the wireless event subsystem,
waproamd may use it to improve latency behaviour. It is not required,
however.</p>
<h3>Configuration</h3>
<p>Edit <tt>/etc/waproamd/waproamd.conf</tt> for configuration
changes. This file is a bourne shell script sourced by the init script
and used to generate a suiting command line. You may specify more than
one ethernet interface in <tt>INTERFACES</tt>. For each interface a
seperate instance of <tt>waproamd</tt> is spawned. The arguments specified in
<tt>ARGS</tt> are append to <tt>waproamd</tt>'s command line. Have a look on
<tt>waproamd -h</tt> or <tt>man waproamd</tt> for further information
about the options available.</p>
<p>Put your WEP keys in <tt>/etc/waproamd/keys/</tt> in files named
after the AP's MAC address with an appended <tt>.wep</tt>. If the AP
uses <a
href="http://0pointer.de/projects/lennart/aeswepd/"><tt>aeswepd</tt></a>
for automatic rekeying, you may put the AES key into a file with the
suffix <tt>.aes</tt> instead.</p>
<p>The configuration is similar to <tt>ifplugd</tt>.</p>
<h3>Troubleshooting</h3>
<p>Not all drivers/cards support the wireless event subsystem of the
Linux wireless extensions. Its support on your machine cannot be
detected automatically, you have to test it yourself with <tt>"iwlist
scan"</tt>. See <tt>man 8 iwlist</tt> for more information. If your
driver/card combination does not support this, you have to enable
polling of association status by passing <tt>-e</tt> on the command
line. This will increase the reaction latency of waproamd.</p>
<h2><a name="requirements">Requirements</a></h2>
<p>A newer Linux Kernel with a compatible device driver and WLAN NIC
(Wireless extensions v15 or newer). Most modern cards and drivers are
compatible, like mines which work with the <a
href="http://www.hostap.org/"><tt>hostap</tt></a> driver, version
0.0.3 and above. The driver has to support the scanning interface,
wireless event support ist nice to have.</p>
<p><tt>waproamd</tt> was developed and tested on Debian GNU/Linux
"testing" from October 2003, it should work on most other Linux
distributions since it uses GNU autoconf for source code
configuration.</p>
<p>The machines used for development are a Medion 9580-F laptop with a
TEAC and a ZONET PCMCIA WLAN NIC. Both cards feature a PRISM2 chipset. <tt>hostap 0.0.4</tt> was used as driver.</p>
<p><tt>waproamd</tt> needs <a
href="http://0pointer.de/lennart/projects/libdaemon/"><tt>libdaemon</tt></a>.</p>
<h2><a name="installation">Installation</a></h2>
<p>As this package is made with the GNU autotools you should run
<tt>./configure</tt> inside the distribution directory for configuring
the source tree. After that you should run <tt>make</tt> for
compilation and <tt>make install</tt> (as root) for installation of
<tt>waproamd</tt>.</p>
<p>The installation scripts create an init script in
<tt>${sysconfdir}/init.d/waproamd</tt>, however no <tt>/etc/rc?.d/</tt> links are created
for it.</p>
