addresses when the dhcp provided address changes.

That appeared to be a firewall issue.
I do see the timeout happening, every so many minutes, did anyone solve
that port. (The head node of that clusters runs IPtables/NAT so that all
the nodes can use AFS as a "common file system" for running MPICH apps)
The authentication server was running. Other clients don't have any
issues at all. (it was a masquerading issue on the head node of that
(PS: "not too many" AFS guru's here.. that's why I am on the list)
