I made a prog which solves the problem of typing and tping in order to hack a WEP.I've heard about spoonwep etc but I've heard about bugs in backtrack 4.Of course this prog is much less important than spoonwep but it becomes extremely useful sometimes.

Open a terminal,go into /hak directory and type "make" without the brackets as root.Type hak as root as well.
