ok. that makes sense. thanks for the explanation :)
I wonder why using the same IP works ok on our intel kit?
perhaps its IPMI is smart and re-injects messages not meant for it back
onto the wire, or does RHEL AS4's NFS just not have a problem with port
623 being used? seems also like it should be pretty easy to hack
portmap to tell it not to use the IPMI port.
