Pyrit Segmentation fault

I am having an issue with pyrit on my linux system and i have no idea how to fix and i hope someone has an answer.

Everything was working fine without any issues until i had to reinstall my desktop. And ever since then i have been unable to get pyrit to work correctly. I have tried lots of linux distros but still have the same result.

I don't know the solution. I have ran into this issue. Seg faults at startup or even at about 4hours into a crack.

 

reinstall nvidia drivers and cuda. I went through this many times. I have a kali usb stick with working pyrit.

Do i need to install nvidia and cuda drivers as my desktop has a amd cpu and radeon gpu? I don't remember having to do that last time

Oh yah, sorry. I'm a nvudia guy. The installation process maybe identical.

 

Maybe start with a fresh kali usb stick? Check if the LIST_cores works.

I have a laptop with an nvidia card and that worked no problem.

I ran dmesg to try and see what my segmentation fault could be and i got this result back:

 

[80391.176164] pyrit[26339]: segfault at 77468 ip 00007f1b63bc6741 sp 00007f1b50ff84b8 error 4 in libLLVM-5.0.so.1[7f1b63163000+3245000]

i have no idea what to do to fix this issue

I was getting no where so i started trying different OS's and i had some limited success using Linux Mint. On the Live CD i install mesa-opencl-icd version 11.2.0-1ubuntu2 (xenial) version as well as my opencl headers and an LLVM 3.8.0.

At this point i can run pyrit benchmark and have it comple normally using my GPU.

Great, I thought. Now all i would have to do is install it to my actual machine and i would be good to go. But Nope.

I installed it to my machine and preformed the same steps as what i did on the live cd before install and i get alot of errors that suddenly appear:

My pyrit stopped working for me as well the other day, no idea why. I got it ro run once then it just stopped(I had another thread in here about it). Never did get it working, which sucks because, like you, I liked pyrit.

I ended up moving over to hashcat and it was easy and it works just as well. I'd honestly suggest that.

I used to love pyrit. I was frustrated by its failure to log data and after 8 hours of cracking and excessive heat (seg fault) with no way to recover or see its last know attempt.

 

I have had a lot of success with pyrit, its a incredible addictive feeling.

 

But there are basic functions that are missing. Pause, stop, restart and zero logging that is the most frustrating part.

 

Move onto hashcat.
