[Csync2] Using Csync2 when hosts are not resolved by dns

[Vadim Comanescu]

Hi Michi,
Thank you very much for your prompt reply. Indeed this solved my problem. Some small changes like starting the server in stand-alone mode as i am on solaris and it works better, and to figure out how to trigger the update. From node1 csync2 -xv -N node1 just works as i expected. 
Maybe I could contribute somehow to the documentation for such a setup, as I consider it to be a very common when one would use a private network for the heartbeat in a cluster. Don't really see a way to do that.

Thanks again, really appreciate it.
Vadim

The problem I have that each time a node would join the cluster i would have to modify the hosts file on each node of the cluster so that csync2 would be able to propagate the changed files to the new node.
