My password files and my pot are majority formed by DES Hashes.
I use JtR version 1.7.3.1 without any patches, downloaded from http://www.openwall.com/john/

My machine brute forcer is old one, 1,7 processor and only 512 RAM memory with Debian Unstable, maybe, slow machine is the problem.
john --show put my processor at 0.7 %CPU and 67 %MEM.

Well, i tried to follow you, i looked for DES_fmt.c file in jtr 1.7.3.1 source, and try to comment block, previous post say, but i couldn't find that loop anywhere...

Any suggestion?

Thank's for help, and Happy Christmas for everybody
