Pyrit Python2.5 segment fault when using CUDA

[Loser3000]

I have been working on a WPA cracking rig using nvidia Gforce 9800GTX+ cards and have been struggling with the same error for a few months now.

I am feeding Crunch into pyrit (r265) into cowpatty and I'm getting about 3000 passwords a second. This will run for either minutes or days and then die with a "fread success error". dmesg says it is something along the lines of a "segment fault...python2.5...error [4,6,7]".

I have tried to run pyrit using "/usr/bin/python2.6 /usr/bin/pyrit...." as well as "/python3/" and they won't even try and run. I have also tried installing the latest pyrit using "/usr/bin/pything2.6 setup.py" and that won't run either.

I am almost positive it is a pyrit issue because I have run crunch into cowpatty and it ran without issue for almost a week. I have also done plenty of other trouble shooting but it would take too long for me to type it all up and nobody wants to read about that much failure.

Any input is appreciated.

I forced an error and received additional information. I know what it says I just have no idea what it means. Any Pyrit programmers out their know what happened?

Edit: Complete re-write; I'm retarded.

I'm guessing you have already found this issue on pyrit's Google Code page

The creator mentions changing "/usr/bin/env python" to point to python2.6

Have you tried this? This way, you wouldn't need to type /usr/bin/python2.6 ./setup.py
My guess is that some of the pyrit code uses /usr/bin/python while compiling. Since /usr/bin/python doesn't point to 2.6, it's not compiling correctly.

This method worked for pyrit r209. You might need to roll back to this revision for it to work.

Derv82 thanks for your reply,

I think I read the same thing you are referencing. I also found that some people had the rest of their system eat itself by having python point to 2.6 instead of 2.5 so I was a little weary.

I'll give it a shot though.

Thanks

I also found that some people had the rest of their system eat itself by having python point to 2.6

Confirmed. Had to reinstall.

I have tried to compile pyrit-3.0 with python 2.6
/usr/bin/python2.6 setup.py build
and the build fails (am I doing that right?)

Anyone else have any ideas or suggestions?

you will have to change the setup files to use the python2.6 you installed.

So /usr/bin/python needs to read /usr/bin/python2.6

So it know which one to build with

i installed in old folder itself how to change this
