    Question Cowpatty / Genpmk noob questions

    I need to build my own hash table to brute force a WPA router that has a unique ssid. A few questions if you guys don't mind:

    (1) I'm running genpmk on my quad core using Win7 since I was hoping it would be faster then my laptop w/ backtrack. But in task manager I notice genpmk will only use 25% CPU max (like it's limited to 1 core). Any way to get it to use all 4 cores? If I boot into backtrack on this machine would it use all 4 cores? Anyway to get my GPU in on the action too?

    (2) Is there a faster way to do this other then using cowpatty/genpmk? My wordlist is 18 million entries (200MB), is that a bit overkill as opposed to using a smaller one and john the ripper? Any general tips are appreciated, I'm new at this.

    Cowpatty/genpkm is a single threaded application. You would be able to make a table faster with airolib-ng (part of aircrack) since it would take advantage of all your cores. Other than that using a compatible GPU device would be the only way to get going any faster.

    No WIN7!
    seriously it looks faster but in the end it takes FOREVER to run anything on it.

    Are you trying to crack the device password? or a WPA key?

    If it's WPA:
    Use BT4 and pyrit to build a db as you go, you could rip though your 18M words no problem.

    pyrit -o - -i (wordlist) passthrough | cowpatty ------- []

    This is basically the code check the Mans to set all the right flags.

    He is trying to make a hash lookup table with a cpu and not a gpu so your instructions will not really help him. Thanks for trying though :-)

    Thanks for the replies folks

    Ya.. genpmk has been running 10 hours now on one core and it's only at 3.5 million out of 18.. I definitely need to step this up a notch. Guess I will abort it & boot the quad core into BT tonight to compare speeds of pyrit and airolib - btw which is faster? do either support using GPU's by default (SLI nvidia gts 250)? is there additional setup I will need to do to get my gpu's involved?

    Pyit lists all CPUs as cores and lists their power in it's benchmark tests.
    I just assumed it would use them to hash.
