Rocks Cluster 6.4 & JtR over 8+ nodes MPI

Sry its Rocks Cluster 6.1.1

On my spare time I am playing with hash cracking while taking college courses for Network Security.

The Project:
  • 7 X Dell PE 2950 (2) QC / 4GB RAM / 73GB HD ( nodes )
  • 1 X Dell PE 2900 (2) DC / 4GB RAM / 3x73GB RAID 0 ( master )
  • 1 X gigabit switch
  • Downloaded john-1.7.9-jumbo
  • Downloaded short & long password lists 250MB & 4.5GB

Whats been done:
  • I have setup the master node & included and installed the other slave nodes via "insert-ether" with no real issue.
  • Compute nodes register on the cluster and are detailed in ganglia
  • Created a general user account on the system
  • As normal user edited john's make file for mpi and ran "make linux-x86-64" as per john's mpi instructions.
  • Created machines file in normal user path for involved compute node
  • Made the standard HPL.dat file in normal user path

The Problem:
I can run john --test locally on master node without issue "mpirun -np 16 ./john --test"

But when I run the same test using the machine file I get errors that the directory or command is not found on remote nodes. "mpirun -np 16 -machinefile machinefile ./john --test". there is a /exports/home/"normal user" DIR on the master node -but- there is no related files including john's dir on the nodes in relation to where it should be according to ROCK documentation. I have resynced the NFS but no change.

The Question:
Am I totally missing something in the case of my user programs and files on the master node and how it is propagated to the compute nodes?

Or am I being dumb and totally not setting up MPI calls correctly?

Other than the Rocks Cluster initial setup is smooth...

Any idea's are appreciated

using a Virtualbox install to see if I can work it out if possible before I re-install ( somethings is goofy with the first install )
