I am a linux noob trying to optimize John the Ripper for a security class. I am trying to use both processors to run John by using the
mpirun program as suggested in this tutorial. I installed
mpirun, but when I run this command, I get the following error:
# sudo mpirun -np2 /usr/share/john --test=10 /usr/bin/mpirun: 1: eval: usr/share/john: Permission denied.
Why am I getting this error and how can I run John with two processors using
mpirun? I am running Ubuntu 12.10 on a VMware Fusion machine on a Mac with an Intel Core i5
