I noticed that in the hostnames YaST widget, box #1 has entries for both boxes, but box #2 has no entries for either box. I believe they should both have entries for both boxes (both are connected to a switch). Should I manually enter this in YaST on box #2, ir is there some other better way to do this, such as joining a windows domain or setting up samba? The goal is to have both of these running a single job via MPI.
I should have said these are two vanilla opensuse 12.1 x64 installations. I thought they should both have their own machine names in YaST/hostnames. I guess one of the machines is misconfigured and I am not sure how to fix the configuration.
