What do you mean "all files"? What about the missing ones?

Ignore MPI until this is solved. If you can't run john on the nodes, you 
can't expect to have them working under MPI.

What is the content of that shell script?

I'm not sure I understand your problem and some of your wordings are not 
helping. For example, you say twice here that you "ssh into a 
directory". Such statements leave me guessing what you really did.

Once you can ssh to each host and succesfully run john, you should be 
able to start an MPI job using all of them - as long as all nodes and 
the master have the same view of the working directories. There's 
nothing more to it.
