Ethereal is a free network protocol analyzer for Unix and Windows. It allows you to examine data from a live network or from a capture file on disk. You can interactively browse the capture data, viewing summary and detail information for each packet. Ethereal has several powerful features, including a rich display filter language and the ability to view the reconstructed stream of a TCP session.

A nifty tool to use when looking to discover access points and save captured traffic. Comes with a configure script and supports Cisco Aironet and random prism2 based cards. Kudos to AC for the USR card.

Airpwn is a platform for injecting application layer data on an 802.11b network. Airpwn requires two 802.11b interfaces, one for listening, and another for injecting. It uses a config file with multiple config sections to respond to specific data packets with arbitrary content.
Now supports WEP and has support for large responses to be split into multiple TCP segments.

kimate is a bash-script for linux with the use to connect to wireless networks, which allow only some clients with special mac-adresses to participate. It analyses log-files from kismet and tests the wlan for them. The whole thing works if one of the special clients leaves the network and you can use the mac-adress for your purpose.
