I am new to backtrack and i am using it to crack a wpa network. I was wondering if there is a way to create a table specific to a ssid and wether to use a txt or a lst file to create the table because i am not having any luck bruteforcing it with aircrack-ng. I am aware there is a utility in cowpatty that does this but i am not sure how to use it and what kind of dictionary to use.
