I was basically suggesting you open a few ports to anyone (e.g. any IP
address), and Jeff suggests you open all ports to a few trusted IP addresses.
btw, how many network ports do you have ?
if you have two

Hello Llolsten
Is there a specific reason you run as root? This practice is discouraged, isn't
it?
Also, isn't it true that OMPI uses ephemeral (i.e. 'user level, randomly
chosen') ports for TCP transport? In that cas
you can direct OpenMPI to only use a specific range of ports (that
should be open in your firewall configuration)
mpirun --mca oob_tcp_static_ipv4_ports - ...
if you use the tcp btl, you can (also) use
mpirun --mca btl_tcp_port_min_v4 --mca btl_tcp_port_range_v4
...
Cheers,
Gilles
