Ive had limited success - I tried cracking the gawker list for two days and got 3 passwords - this of course was with zero tuning .. just pointing jtr 1.7.6 with some patches at the files and using MPI. I'm not %100 I'm doing it right. But a question for SolarDesigner - does your roadmap for jtr define any distributed capabilities? I suppose what I'm getting at is "are we stuck with mpi"? -Dan > On Wed, 2010-12-15 at 23:52 +0300, Solar Designer wrote: >> Hi, >> >> Here's a curious blog post by Jon Oberheide: >> >> http://www.duosecurity.com/blog/entry/brief_analysis_of_the_gawker_password_dump >> >> People are actually starting to make use of the OpenMP support/patches >> in/for recent versions of John the Ripper.
