Hi all

I am using backtrack off a usb memory strick(live install made with unetbootin)with crunch 3.0 installed. when i try to pipe the output of crunch into aircrack with the following command it runs ok for about 2 mins at just over 1000 kps but then the system shuts down

/pentest/passwords/crunch/crunch 8 8 | aircrack-ng -e ???????? -w - /pentest/wireless/aircrack-ng/handshake/wpa.cap

Anyone have any ideas??

Also is there any way to stop crunch trying a combination with 3 of the same characters in a row? as this will vastly reduce my combinations

Thanks for any help
