Noticed that the ethers files was a bit screwed up following our cluster install. For \
one rack of compute nodes Rocks repeated the same hostname for all the MAC addresses \
but was ok for all the rest of the compute nodes. Result of this was that one node \
was unreachable from the head node due to the incorrect entry in the ARP table.

This is what we ended up with:

Was fine for all the other nodes. An easy fix once I tracked it down but thought I'd \
mention it just in case it shows up for anyone else.

John Kissane.
