aircrack not working even with wpa key in dictionary

[Maxime Alarie]

Im not a security expert,  but  .. 
To save you some time.. If you have a WEP encryption,   it'll be
cracked.  If you have a WPA or WPA2 encryption key, and a huge
dictionary, it can be cracked if your passphrase is a word in a language
dictionary (I think  the biggest list is 40 million words). If your
passwors is like p at 55w0rd.


You may already know this but you might find the answer you are looking
for on the Backtrack forums.  Backtrack is a special Linux Distribution
built for penetration testing: http://www.backtrack-linux.org/forums/

Subject: aircrack not working even with wpa key in dictionary

Hi all,
to test my wireless network I played with airodump and aircrack
following the 
tutorial
here:http://www.ubuntu-unleashed.com/2007/08/howto-aircrack-ng-quick-
and-simple.html.

Now I've captured packets untill airodump presented me the WPA-PSK
handshake 
title in the top right corner of the screen. Then I stopped the program 
airodump, and tried to guess the passprhase using the dictionary of john
the 
ripper:

aircrack-ng -w /usr/share/john/password.lst *.cap

and the program quitted after testing (only) 472 keys without founding
the 
right one. So I added the right passphrase to the dictionary, as last
entry, 
and ran it again, but the system is still unable to guess the
passphrase.  Am 
I doing something wrong?

Luca
