Haven't messed about much either, i used it mainly to test my own network (god
i miss that UTP cable) and did a quick drive through of the neighbourhood
checking out their networks.
Perhaps i'm one of the few who just likes to read a ton first and then try it
out a bit.
anyway, the tables in reality are only +-36gb so that saves a bit of time :p

also yeah I havent messed too much with wpa so da_eternal yeah you are very
right about psk and the rainbow tables and junkness. I'll have to do some more
research in this area myself and start on that juicy 40gb download.

Thanks Adese. Yes bruteforce attack against a WPA are only posible when the
key is no more than 8, and then only if they aren´t very imaginative.
I have the possibility of capturing handshakes and there seems to be a few
everyday, does aircrack support doing this?
Where can I get a detailed information of the airodump, aircrack and air
replay functions?

router.
bruteforcing with JTR could take a very long time. refer to this :
http://lastbit.com/pswcalc.asp so you can start disappointing yourself.
this is why you should at least try a dictionary attack with a real big
wordlist before you try the lengthy task of bruteforcing.

How long could Jacktheripper take to crack WPA?
Is it possible to capture a handshake, how many handshake could you
need?
