VCL + Hashcat Troubles

[roflcopter]

Hi all,

I am attempting to setup VCL with Hashcat 0.15. After setting up the broker and the computer nodes, when executing any hash cracking function, the program hangs after the cards have been identified. I have tried several variations found in this forum to resolve this issue, most common being the VCL restart command on all nodes, but that was no-such-luck.

I decided to try the Hashcat 0.14 version, which requires Catalyst 13.1 drivers on the computer nodes. However, this is very difficult to install on the latest Ubuntu, and throws several errors about not having all the necessary files in order to install (linux header.h files I believe). I tried an earlier version of Ubuntu, the drivers install, but upon the next boot, I am greeted with the "AMD Unsupported Hardware" watermark at the bottom-right corner of the screen.

Does anyone have any ideas as to how I can resolve these issues?

Specs:

GPUs: VisionTek HD 7970
Distro: Ubuntu 12.04.3 (and tried 12.04.1 as well)

Thanks!

I've gotten the Catalyst 13.1 driver to successfully install on Ubuntu 12.04.2, but it appears that for Hashcat 0.14, that it just sits there after listing off all 3 devices. Thereafter, it mentions Device #1 Kernel and some information on that same line. Any thoughts as to why?

Here is the current output after it hangs:
