Hi,

If I give the localhost as value for the Listen Address for the machine (and this the Node Manager), I can start/stop any managed server belonging to the domain
and related machine.

When I change this address to the value of the IP address I get from "ping hostname" (that is to be found in /etc/hosts), or the corresponding host name found in /etc/hosts,
I get the following Warning from the Console:

- For server <managed server>, the Node Manager associated with machine MyMachine02 is not reachable.
- All of the servers selected are currently in a state which is incompatible with this operation or are not associated with a running Node Manager or you are not authorized to perform the action requested. No action will be performed.

Can someone explain me how can a machine and the node manager be configured with another value than localhost for the Listen Address?
Is there maybe a configuration that must be done at physical server level?

Having this functionality will be a necessity for a cluster.

Thanks by advance for sharing your experience.
