Today at work a client he needed to access a cisco router but no-one new the password but we had the config files saved which included the MD5 hashes of the enable and enable secret passwords. So I set about cracking the hashes, which was done successfully btw, following on from that I then remembered a John the Ripper MPI patch which I had seen some time ago I ended getting it going at home and the results are good!

Directions for installation are as follows (on Fedora 11)

yum install mpich2 mpich2-devel
tar -zxvf john-1.7.2-bp17-mpi8.tar.gz
cd john-1.7.2-bp17/src
make linux-x86-64 (for 64bit version duh!)
cd ../run
touch ~/.mpd.conf && echo "MPD_SECRETWORD=secret" > ~/.mpd.conf && chmod 600 ~/.mpd.conf
mpd & -n 4 -path ./ -wdir ./ ./john --test

Initial Benchmarking looks good. Below is 1 core vs 4 cores

About a 100% increase per core! Life is good!
