This might not be a libtirpc program, but maybe someone here can shed some light on the problem.
"rpcinfo -b <prognum> <versnum>" sends a broadcast to RPC service routine 0 for the given program and version number. The problem is that none of our servers on Redhat 8.10 (and, I think, other redhat versions) responds to it. We have lots of Solaris hosts and they all respond as they should.
Does anyone know why this might be happening? ifconfig shows that broadcast is enabled.
Thanks,
Dave
