Hi All,

little background.

I am running an AMD 1055T Overclocked to 3.6Ghz at highest speed Ive lowered this down as I am running a WPA crack using pyrit & crunch.

My pc
AMD clockspeed about 3.4GHZ six cores
I am also using CUDA on an Nvidia GTX260 (this is quite an old card I had lying around)
8Gig Ram
Backtrack 5r1 fully patched working with cuda.

I also have a linux server box well webserver as well which just sits there all day not doing much.

This is a 3Ghz Dual core AMD
2gig Ram
1TB harddisk
no special card or other bits.


What I would like to do is run "./crunch 10 10 -f charset.lst lalpha-numeric -i -d 1 -s abababababab -u | pyrit -i - -r mywpa.cap - mywifi attack_passthrough"
This command will bruteforce to pyrit starting from abababababab

All well and good as its running this now on my BT box I am getting aprox 14000PMKs

I would like to shift some of the load onto my other linux box I know it can be done with pyrit but if I want to do this will I have to generate a 32Pbyte wordlist then import that into pyrit then I can attack that using multipule machines or is it possible to do this using the command i have with crunch?

Many thanks.
To give you an idea of what I have tried ...

I ran a vm on my windows machine running Backtrack 5
I then run crunch with the above command but created a 50gig file once this was completed I compressed this file using gzip then tar'd it to make it smaller the resulting zipped size was about 10-11gig
It got to the stage where I couldnt zip up my files fast enough.... I had some serious fun in the beginning crunch filled a 3TB eternal harddrive in just over a day it was amazing I came home expecting the drive to have been about half full but it just gobbled up 3TBs way cool...

Anyway if anyone has any ideas
So you are aware I have the 4 way handshake I captured this using airodump-ng I also verified this using pyrit and checked in wireshark for the EAPOL(i might have that wrong)



So again 2 machines I would like to spread the load so to speak

Thanks all....

Live long and prosper

Many thanks for your quick reply,

I have actually been watching the threads on BT forums...

What I am trying to do might not be possible its ive seen clusters sharing cpu work...

What I am doing is a bruteforce so I dont have a text file to use so would be unable to spread the load across each of the machines although I may end up doing this.

Thanks for your reply.

Correct if I am wrong, but doesn't Pyrit only use dictionary files? Instead of pure brute forcing!

I would set up Pyrit and the server setup as described in the links.

then you can run a command like

crunch 10 10 0123456789 | pyrit -i '-' -r keyfile attackpassthru

and if the servers are all setup and running it should work as a cluster.

But after looking at the systems you are using It might be more effective to buy a 100 dollar video card that will do more pmk that your setup clustered for like half the power cost and the lack of use of whatever machines are doing the cracking.

You just have to make sure the servers are running on other machines and you have set the pyrit config file to know about them.

have you looked at oclhashcat-plus?

[TheRaver]

Hi Infiltrator,

no you can pipe data from number crunchers like crunch. which is what i had started to do...
But i dont think it was possible to do a cluster without using a dictionary.

As a starting point I am creating a 27Pbyte list I am on about 5Tbytes with a week of crunching

Cheers

Hi intertan no I havent looked at oclhashcat-plus I've had a read about it but havent had any experience yet.

Hi leapole,

my intention is weavering towards 2-3 AMD 5870s as they seem to get about 32000Psk
My ideal setup would be my trusty GTX260 on my server box running 2Gig Ram & a 3Ghz Quad AMD
Then my normal BT5 box running AMD 1055 6 cores overclocked 3Ghz per core with 2-3 5870s I can fit upto 4 cards on my board.

Thanks again I am constantly reading and learning and am always open to suggestions.

If anyone is interested
55 files of 100Gig compressed with bzip2 to 8gig a file.
This hasn't really touched much of the create list lalphanumeric.

Cheers

Nice. You should have nps using the pipe for the cluster. You might want to setup the database up so you can save all the crunch that you do. Pyrit is an extensive program and well setup for your plans.
