This is pretty much a complete rip of this site: http://www.wsec.be/blog/2010/09/27/optimizing-john-the-ripper-for-multiple-cores/
and mainly just for my own quick reference.
So the first thing we need is to install some stuff. I did this on Ubuntu 10.04.
sudo apt-get install libmpich1.0-dev libmpich-mpd1.0-dev libmpich-shmem1.0-dev mpich2 mpich2-doc john libssl-dev
Download the source-code for the MPI-version of JtR here: http://www.bindshell.net/tools/johntheripper/john-1.7.3.1-all-2-mpi8.tar.gz
Extract the file by running this:
tar -zxvf john-1.7.3.1-all-2-mpi8.tar.gz
cd into the src-folder and compile JtR for the 64-bit platform by running this:
make linux-x86-64
mpd (of mpich2) is some sort of multi-processor thingy that lets us run JtR in multiple processes. To make it work, we need to create a conf-file for it’s daemon. Do this by running nano /etc/mpd.conf and enter this single line:
MPD_SECRETWORD=secret
Afterwards, do chmod 600 /etc/mpd.conf to make it accessible to the right people.
Now start the daemon by running mpd –daemon
cd into the run-directory and run JtR like this:
mpirun -np 8 ./john <regular jtr-switches>
This will make it run in 8 processes, and is awesome on an i7 system. Here’s a comparison:
