Overview

   waproamd 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.

   Due to driver and stability issues, starting from version 0.5 ifplugd
   is no longer recommended for joint use with waproamd. The default
   action scripts of waproamd are modified accordingly: they run
   ifup/ifdown on their own behalf when a new network became available or
   and old one is lost. If you like you may still use waproamd and
   ifplugd on the same interface together, but you have to modify the
   default configuration to reflect that.

   An alternative implementation of a tool like this is [17]wlandetect.

Status

   Version 0.6 works fine on [18]hostap 0.0.4 and airolan. Other
   driver/card combinations not tested, but may work too.

Documentation

   Have a look on the man pages [19]waproamd(8), [20]waproamd.conf(5).
   (An XSLT capable browser is required)

  Mode of Operation

   As long as the local NIC is not associated to any wireless network
   waproamd scans iteratively for them. If one is detected, a script in
   /etc/waproamd/scripts/ named after the MAC address of the access point
   is called. (First lowercase, than uppercase is checked) If a script
   like this is not found a script named essid:<ESSID> in the same
   directory is used. Special characters are escaped in an HTTP URL like
   fashion. If this script is not existent, /etc/waproamd/scripts/default
   is called instead. The first argument to this script is "start". If
   the association is lost, the same script is run with the argument
   "stop". While the NIC is associated no scans are issued.

   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.

   waproamd 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 "iwlist scan". If
   the driver supports the wireless event subsystem, waproamd may use it
   to improve latency behaviour. It is not required, however.

   waproamd supports the host_roaming private ioctl() as defined by the
   [21]hostap driver.

   Don't forget to install a firewall on your computer, since waproamd
   will try to log into any network it finds with default settings, if
   not configured otherwise. Yes, you a right, waproamd is war-driving on
   steroids.

  Configuration

   Edit /etc/waproamd/waproamd.conf 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 INTERFACES. For each interface a seperate
   instance of waproamd is spawned. The arguments specified in ARGS are
   appended to waproamd's command line. Have a look on waproamd -h or man
   waproamd for further information about the options available.

   Put your WEP keys in /etc/waproamd/keys/ in files named after the AP's
   MAC address with an appended .wep. If the AP uses [22]aeswepd for
   automatic rekeying, you may put the AES key into a file with the
   suffix .aes instead.

   The configuration is similar to [23]ifplugd.

  Troubleshooting

   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 "iwlist
   scan". See man 8 iwlist for more information. If your driver/card
   combination does not support this, you have to enable polling of
   association status by passing -e on the command line. This will
   increase the reaction latency of waproamd.

   You can priorize networks over others by adding symbolic links to the
   default script to /etc/waproamd/scripts.

Requirements

   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 [24]hostap driver, version
   0.0.3 and above. The driver has to support the scanning interface,
   wireless event support ist nice to have.

   waproamd 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.

   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.
   hostap 0.0.4 was used as driver.

   waproamd needs [25]libdaemon.

Installation

   As this package is made with the GNU autotools you should run
   ./configure inside the distribution directory for configuring the
   source tree. After that you should run make for compilation and make
   install (as root) for installation of waproamd.

   The installation scripts create an init script in
   ${sysconfdir}/init.d/waproamd, however no /etc/rc?.d/ links are
   created for it.
