Hello,
my cluster does a simple thing:
- a node is asking everybody - "do you have this thing?"
- if yes - "give it to me"
- if not - "I'll make it myself"

It is all done via RpcDispatcher and everything works well on my local
machine, when I'm running all the nodes locally.

Once I've deployed it on the Virtual Machines in Data Center (Digital
Ocean), my nodes stopped seeing each other.

I've tried to troubleshoot by following the documentation, but I'm no
Linux/LAN expert.
I guess I need to set up my Linux (CentOS) to support unicast, or something
like this.
Could you point me to some direction, where I could find exactly what I
need? Or better if there is a step by step documentation of how to enable
Linux Cluster work with JGroups?

BTW: I'm using default configuration udp.xml, maybe I could use some other
config file, which would make my life easier running the cluster in a Data
Center?

Thanks in advance,
Eugene
