Yes, all the machines participating in the grid have valid IP addresses
on their interfaces.

I assume that both of you have seen the reply from Aleksej Saushev,
who seems to be the bloke looking after the port of OpenMPI to the
NetBSD platform.

Aleksej suggested some mods he had partially looked at, in

opal/util/if.c

was that were you would have told me to go Jeff ?

I have not as yet tried anything.

I am awaiting being given the local ability to build the OpenMPI
within the NetBSD PkgSrc environment and am building externally
to it at present, so would be happy/able to try any suggestions
out.

Kevin
