Quitting aircrack-ng..

What exactly are you trying to do? Are you trying to crack wep or WPA? To crack WPA you need to run a "wordlist" against the "handshake". If a word in your list is the password you have cracked it. BT comes with some small wordlists or you can download larger lists from the internet.
