[rabbitmq-discuss] RabbitMQ Clustering issue - (2x Virtual Box OpenSuse machines) (NOOB)

[Liam Reilly]

I've got a couple of OpenSuse VM's configured in Virtual Box.  

I have rabbit running on both.

rabbit at devserver
rabbit at devagent

I've added both machines to each others hosts files and I can do a sudo 
/usr/sbin/rabbitmqctl -n rabbit@{hostname} status from either machine to 
see the full status output of the node.

So both machines are happy at this point.  

I've also got Celery working and load balancing tasks using the 
rabbit at devserver RabbitMQ queue.

Now I stopped the rabbit at devagent instance and tried to add to the 
@devserver using the cluster command

sudo /usr/sbin/rabbitmqctl cluster rabbit at devserver 

to which I get 

Clustering node rabbit at devagent with [rabbit at devserver] ...
Error: unable to connect to node rabbit at devagent:  nodedown

DIAGNOSTICS

nodes in question:  [rabbit at devagent]

hosts, their running nodes and ports:
- devagent:  [{rabbitmqctl10831, 48309}]

current node details:
- node name rabbitmqctl10831 at devagent
- home dir: /var/lib/rabbitmq
- cookie hash:  LczRqz4mQrqdzWYMcog==

I have modified the erlang cookie on both machines so these match btw.

Any idea's?
