Hello,
The cluster communication is nothing more that SSH traffic. (Ok.. which an be any traffic in a tunnel)
We are using the TCP2222 port but if I remember the manual correct there is even a notice that customers are advised to use the standard SSH interface in stead of the CCS interface.
I'm not sure what is behind that advice, maybe someone from HQ can clear this up and give me an argument to migrate from CCS to SSH..
Steven
