hi ,

when I'm writing continuation lines

Code:
/pentest/passwords/john/john --stdout --incremental :all | pyrit -e meine_essid -i - -o -passthrough | cowpatty -r /root/Victim.cap -d - -s meine_essid
than i will become this output:

Code:
cowpatty 4.6 - WPA-PSK dictionary attack. <jwright@hasborg.com>

Password files specified, but no option would use them
Collected all necessary data to mount crack against WPA2/PSK passphrase.
Starting dictionary attack.  Please be patient.
Using STDIN for hashfile contents.
