Subject: Re: [OMPI users] open mpi on non standard ssh port

We don't have an easy way to specify using different ports for each
host (this is a fairly uncommon configuration), but you can set it up
in your $HOME/.ssh/config file, perhaps something like this:

Host 192.168.0.101
     Port 5101
Host 192.168.0.102
     Port 5102

...and so on. Then "ssh 192.168.0.101" will automatically uses port
5101, etc.

See the man page for ssh_config(5) for details.
