<wpa-buddy> wpa-buddy is a tool to decrypt WPA-PSK protected traffic. It can work in real-time (sniffing packets from a network interface) or in batch mode (reading packets from a capture file). It also produces nice output telling you what's going on. wpa-buddy currently supports WPA and WPA2 (this last only in the unstable version).<AIRCRACK FAQ> AIRCRACK FAQ

aircrack documentation Cracking the WEP

Now we have a file ready to be sent to the butcher. This is where Aircrack comes in. It will use the Airodump data and start the cracking process to generate the correct key. To break 128 bit WEP, the file will need to have 200,000 to 700,000 unique IV packets. Assuming that we have a good enough file, we attack the file to get the key. Using Aircrack, the command should look like this from the root level command line shell:

root@home[]# aircrack -f 2 -m XX:XX:XX:XX:XX:XX -n 128 -q 3 keygen*.cap
<MAC address> How do I change my card's MAC address ?

Under linux: for example, if you have an Atheros card:
ifconfig ath0 down
ifconfig ath0 hw ether 00:11:22:33:44:55
ifconfig ath0 up

Pay attention, it doesn’t work with all drivers.
Under Windows, you may use macmakeup.

If you want to associate to this AP with linux :
iwconfig ath0 mode managed essid key 9A:22:XX:XX:XX channel

with Windows :
enter the key : 9A22XXXXXX in windows wifi manager
