CPU v GPU configuration

[weitenma]

Hey gang...
I am currently running a recent version of hashcat (hashcat -V pull/1273/head) on an Ubuntu 18 VM.

When running a crack against an MS Office doc, I have to use the --force option which produces this output:


hashcat -m9600 '<obfuscated hash>' -o test05 --force

Device #1: pthread-Intel(R) Core(TM) i7-4870HQ CPU @ 2.50GHz, 1478/1478 MB allocatable, 4MCU

Hashes: 1 digests; 1 unique digests, 1 unique salts
Bitmaps: 16 bits, 65536 entries, 0x0000ffff mask, 262144 bytes, 5/13 rotates
Rules: 1

Applicable optimizers:
* Zero-Byte
* Single-Hash
* Single-Salt

The above keeps repeating itself and the Speed.Dev.#1 never increases.  It works 'normally' on other hashes and I get 'normal' results.

Is there a file that I can edit to force the DEVICE_TYPE to 1 to force to CPU?  I have to use --force to get hashcat to work at all in the current configuration.

Thanks in advance from the new guy!  Let me know if there are any questions or clarifications...
