The other cluster that I finished last month is on the same physical network,
so need to choose a different port number so ganglia doesn't see them.

I reinstalled very carefully this time. I think previously I missed the second
port number entry on the ganglia config screen (could that screen be
enlarged so scrolling is not necessary?)
After Complete Cluster Setup, the ganglia webpage still did not see the
nodes. I also re-ran Complete Cluster Setup, both in the current session,
and after quit, logout, login, oscar_wizard, but still no nodes showed up.
I had to edit the port under udp_send_channel (only) on each node and
restart gmond on all nodes, then they all showed up on the webpage.
[perhaps it is not pushing gmond.conf to the nodes?]

I only have one image on this (suse) cluster, and it is a different frontnode
from the other (CentOS) cluster. Different subnets too, just happens to be
on the same switch.
