<div dir="ltr">Thanks Jason. The cookies are the same. Running anything from rabbitmqctl to the remote host fails, unfortunately. The list_queues call fails to connect, the same as join_cluster.<div><br></div><div>As I indicated, the telnets all work just fine, so I'm stuck for what to diagnose next. Any ideas would be great.</div>

I THINK that's rabbitmqctl -n <servernode> list_queues for example. If both servers can talk to each other then it should be rabbitmqctl stop_app, join_cluster, start_app.<br>

This is different than the script at <a href="http://www.rabbitmq.com/clustering.html" target="_blank">http://www.rabbitmq.com/clustering.html</a>, which says to start with "rabbitmq-server -detached".

<div><br></div><div>So, the script says to stop the RMQ2 server and then join the cluster. The following transcript shows how well all this goes:</div><div><br></div><div><div><font face="courier new, monospace">02:~$ sudo rabbitmqctl stop_app</font></div>

<div><font face="arial, helvetica, sans-serif"><br></font></div><div><font face="arial, helvetica, sans-serif">However, as I said above, telnetting to the ports works just fine:</font></div><div><font face="arial, helvetica, sans-serif"><br>
