Hashcat not recognizing my GPU - aku - 05-22-2020

I am running debian with the the latest driver for my graphics card available. Hashcat doesn't seem to detect my card or use CUDA when it runs. Any advice?

Code:
$ nvidia-smi

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

my nvidia card appears to be installed correctly with CUDA 10.2 - why isn't it being recognized?

RE: Hashcat not recognizing my GPU - philsmd - 05-22-2020

see: https://hashcat.net/faq/wrongdriver

also test with
Code:
clinfo
to test and make sure it's working with other tools and therefore is not a hashcat problem.

Thanks for responding phil - my driver appears to be correct (367.x or later for nvidia and I have 440.82) but clinfo isn't detecting my card at all!

clinfo has a lot of information about my CPU, here's the relevant info  -

nvidia-current would be the NVIDIA driver 440.82, right?

running hashcat as root gives me this output:

This is pretty close to fixing my problem, but I tried to follow the post in the stack exchange link above and couldn't find libOpenCL.so or libcl.so, even with root access...

RE: Hashcat not recognizing my GPU - philsmd - 05-22-2020

it's not clear what the problem now is.

Does clinfo only work (i.e. list your devices) with root ? that would be very bad and just proofs that your driver installation/configuration is broken. It would also proof that hashcat has nothing to do with the problem, if also other tools can't see your devices with non-root users.

RE: Hashcat not recognizing my GPU - MicroPanda123 - 05-23-2020

I don't know if that will help, but when i had this problem, i just deleted completly nvidia drivers, and used "sudo apt-get install -y nvidia-driver nvidia-cuda-toolkit" and it worked for me.

"The pocl project"

That's not likely to work well. I've had terrible trouble with POCL getting in the way of my other OpenCL configs, and I've basically blacklisted it from my systems now, it's more trouble than it's worth. Uninstall anything listed by `dpkg -l |grep pocl`, if necessary install `ocl-icd-libopencl1`, and you'll almost certainly have a much better time.
