Hello 
I'm on the latest The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) Linux (brand new install).
Code: ─$ cat /proc/version
Linux version 6.6.15-amd64 (devel@The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali).org) (gcc-13 (Debian 13.2.0-13) 13.2.0, GNU ld (GNU Binutils for Debian) 2.42) #1 SMP PREEMPT_DYNAMIC The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) 6.6.15-2kali1 (2024-04-09)
I have an old GPU, so I installed "legacy nvidia driver", the latest one, which supports my GPU, and still receives updates.

The compatible CUDA version is indicated to be 11.4 (not only as the output of nvidia-smi but also in the official documentation).
When I run hashcat to use CUDA, I unfortunately run into the following issue:
Code: ─$ hashcat -m 0 -a 0 hash.txt /usr/share/wordlists/fasttrack.txt

This is a common error. Try using `--backend-ignore-cuda` and it should work, it's just because your hardware is very old that nvrtc isn't very happy and neither is k ali

I installed via nvidia-tesla-470 package for my legacy GPU and executed the runfile for CUDA 11.4
When installing CUDA via the runfile, multiple packages can be installed (of which, a driver that goes with CUDA 11.4).
I did not install the driver shipped with the runfile, only the CUDA toolkit.

Hello @penguinkeeper,
Sorry, I missed your post while supplementing additional data.
Thanks for your response!
I'm aware that I can run hashcat on my CPU. However, I hope it will be faster on my GPU, albeit nothing comparable to a modern GPU (or CPU for that matter).
Is there a way to make nvrtc happy with my old hardware?

Oh that's interesting that you don't have an OpenCL interface for your GPU, I didn't notice. That's incredibly rare. You may have to install OpenCL separately but as the forum has picked up on, The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) doesn't handle OpenCL at all well so if you can, it may just be easier to switch to a different distro or to Windows. It is possible to fix your error but would mean you'd have to edit code and I can't promise it'll be stable or accurate after the relatively brief modification

That seems completely off, no?
I'm looking here and I see the API is OpenCL https://compubench.com/device.jsp?benchm...e+GTX+870M
(well, it says Windows, but still)
I'm also pretty sure I've used this GPU, with this old laptop in the past both on windows and ubuntu, to perform some GPU CUDA tasks on hashcat...
It seems unnatural to me that the distribution made for pentesting has the most difficulty with harnessing GPU for password cracking haha
What can I do to make sure I haven't messed up anything related to the configuration/drivers?
What version of OpenCL should I install?
If you can shine some light on that matter
Thanks!

Yeah, welcome to the state of security tooling in general.
