CUDA Issues with Nvidia 3080s (hc v6.2.5) - rumham - 07-29-2022
Hey all, I recently built a new rig and am running into an issue with what appears to be CUDA from my hashcat output. Pretty strange as I believe I've installed the proper nvidia drivers and latest cuda sdk toolkit. I'm sure I'm missing something simple here... Below is some output from my system.
GPU info:
4x Gigabyte NVIDIA GeForce RTX 3080
Hashcat Version = v6.2.5
uname -a
Code:
Linux loki 5.15.0-43-generic #46-Ubuntu SMP Tue Jul 12 10:30:17 UTC 2022 x86_64 x86_64 x86_64 GNU/LinuxHashcat output testing benchmark against NTLMv2.
Code:
hashcat -m 5600 -b
hashcat (v6.2.5) starting in benchmark mode
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.

Did you follow the post installation steps of adding everything to the PATH/ENV?

Hey Chick3nman, thanks for the assist there. That fixed the issue above. Now I'm running into an additional problem. Seems hashcat is hanging directly after listing the devices and right before starting a benchmark:
Code:
hashcat (v5.1.0) starting in benchmark mode...

Quote:hashcat (v5.1.0) starting in benchmark mode...
seems you are invoking an old installed version of hashcat (distribution?) instead of your downloaded/self compiled one
try running directly in your 6.2.5 directory with prepended ./

Okay so I went back and ran with v6.2.5 and am getting the same CUDA issue again. Not sure what the difference being with v.5.1.0 and v.6.2.5.
I did make sure to double check that I followed this exactly https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#post-installation-actions

can you please show your output of hashcat -I
benchmark tries all possible devices and it seem it starts with opencl on your cards instead of cuda
