Hi Mike,

I recommend checking if you have a firewall that's blocking traffic on 
any or all of the nodes.
Perhaps you can temporarily "service iptables stop" and see if it 
connects that way.
If that's your problem, here is a link to which ports to enable:

http://sources.redhat.com/cluster/faq.html#iptables

If that's not your problem, please let everyone know what version of the 
cluster
software you're running.  There are vast differences between the stable 
code
(such as STABLE in cvs and RHEL4, etc) and the development code (HEAD in 
cvs).
