mate, can u pls explain a lil more. i am also in a need of this kinda thing...
unfortunately today the backtrack servers has an internal error. its a linux operating system based on ubuntu kde running with a patched kernel to support penetrative, analytical, forensics and much more. download it, use 32 or 64 architecture, make sure u r downloading ISO,
Either burn it or run it using VM player.
(google for this!) and if u burnt it on a CD and boot live CD.
you should be having a network card which can be put in to monitoring mode. u can check it using terminal on back track and type
airmon-ng
then it will show your interface mostly this is wlan0 or mon0 oe eth0 depending up on ur card, then type
airmon-ng start (your interface)
my one is wlan0 so i type it as
airmon-ng start wlan0
then if its enableing monitoring mode.. ( you can see that on terminal)
you can do much more things than hacking wep and all...
learn these not to harm or steal credentials or spy on anyone. just use this to find out and explore the vulnerabilities.
