Subject Re: Setting up a multi-node cluster
Date Thu, 29 Aug 2013 05:41:07 GMT
Hi John,

I had my firewall disabled in both the nodes
To make sure. I checked it
# rcSuSEfirewall2 status
Checking the status of SuSEfirewall2
                                                                 unused

if it's, on it says running

Please suggest the further steps, where to look and troubleshoot, if you
have any idea
