The ability to be able to (kick) deauthenticate a client is very important to be able to do if you don't want to wait around for ever to collect the 4Way handshake.

If you had a deauthenticate button in Faircrack you could collect the 4Way handshake in seconds.

We could also do with pyrit on the N900 so we can check that the captured WPA 4Way handshake is good because sometimes airodump-ng says the 4Way handshake has been collected but it does not contain enough information so is no good.

If anyone knows where to obtain a copy of pyrit which has been compiled for the N900 could you post a link.
