[rabbitmq-discuss] Initial cluster set-up questoin

Wed Dec 14 08:47:19 GMT 2011

Hi,

	I have installed Rabbit & Erlang and followed these instruction
http://www.rabbitmq.com/clustering.html to set-up a two node cluster.
Both nodes are be started, but when node 2 attempts to join node 1 it
fails.

There are no firewalls between each other. Both are on the same vlan and
a /22 subnet.

O/S: RHEL 6.2  Fully patched from RHN.

Node 1:

I have tried the command above with the FQDN and had the same error
returned.

Any ideas where I could look?
