Hey
A bit inspired by ippsec’s cracker machine to crack hashes on an external machine. I have installed an older laptop with kali in my junk drawer.
Not quite state of the art, but it’s just practice, isn’t it? 
Only I run into some problems with hashcat, in particular that it cannot find devices. The only option I have to use hashcat is with the --force option. Actually, I don’t want this, after all, after the exercise we also want to gain some speed compared to hashcat in the VM.
Now I have already been google a bit but I don’t really get any further. Some posts suggest it has to do with AMD no longer supporting some things. But I can remember that hashcat used to run in the past, maybe something about lumping with an installation or something like that.
Long story … short story I hope any of you can help me with this.
Below some commands and output with which I tried to find out some things.
hashcat -I
hashcat (v5.1.0) starting...
No devices found/left
hascat -- benchmark
hashcat (v5.1.0) 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.
* Device #1: Not a native Intel OpenCL runtime. Expect massive speed loss.
You can use --force to override, but do not report related errors.

And so there are other commands I have tried to gain insight, including openCL installed after every major step of installing something a reboot, unfortunately no result at all.

I am now on completely new ice, so it may be that I have used completely unnecessary commands and / or that I am missing something important.
Anyway, I hope someone has an idea of what’s going on here and more importantly how I can fix it. In any case, thanks in advance
