Hi,

I've previously installed a Rocks-6.1.1 cluster which comletely works as it should.

Now, I recently mentioned on this list about network-problems with a new cluster, \
caused by the reason that I had to change the public and private Ips of the headnode. \
At the end I fixed all anomalies, such as pxe-boot-server address and routing tables, \
but I was unable to get ganglia see the compute node (I just started with 1 compute \
node...). Then I decided to start allover and reinstall the frontnode with Rocks-6.2, \
and deploy 1 compute node. All seems fine now, but I still cannot get ganglia to see \
more than the frontnode.

What is missing here ?

- /etc/ganglia/gmond.conf seems right on both frontnode and compute node
- /etc/ganglia/gmetad.conf seems right on frontnode
- services gmetad and gmond restarted on frontnode, gmond restarted on compute-node.

Still no luck.

- $ gstat -a only shows frontnode.

Private network is on a basic DELL switch.

How can I test 'multi-cast'-ability of my private network ?

Regards,
Carel
