It is the "only" way, Solar just didn't know about it. Latest Hashcat 
can do it on its own, but the previous version needed od6config. We are 
not currently planning to add any such things to Jumbo, just keep using

I would use --autofix. It is the way to go if you want maximum 
performance without overclocking. Do not bother overclocking until you 
master everything else.

"My case" is a laptop. I do not own a 290X but yes, it sounds like a 
chinese vacuum cleaner if you set it to 100%. You can use a lower fan 
setting but it may lead to worse performance (card will throttle clocks 
instead, to keep temps down).

We can't. How are we supposed to know whether you mean "default 
wordlist, and hashfiles file1 and file2", or "wordlist file1, and 
hashfile file2"? It is just ambigous.

It read /test.txt and hashes.txt as two hash files. It must have found 
108 valid hashes in /test.txt. This indicates you have a wordlist of 
poor quality but that is another issue.

Go with Hashcat's recommendations (currently 14.4 which is also the 
latest release). That way you can use both JtR and Hashcat.

Jeremi Gosney, yes.
