I've been wondering about this for some time, but have never found anywhere, other than a few obscure archived forum posts on the topic, that shed much light on this problem.
John the Ripper (I HOPE you know what that is ), has an MPI build available, and I have to say, it works quite well. (By the way, my cluster on consists of a five node test environment with about 12GHz and 10GB RAM all up but it's better than nothing ).
However, when it comes to WPA hash cracking, JTR falls short. I've done the usually generating combinations with JTR, and piping that into aircrack, but aircrack does a HORRIBLE job of running on more than one core!
I was wondering if anybody knew of a program (does coWPAtty work I've never tried it) that support multiple cores/a cluster environment?
All responses appreciated!
