[rabbitmq-discuss] Rabbit client works from one machine but not another

[Steve Leibman]

Hi,

I have RabbitMQ client code (I've reproduced the issue with just the sample 
consumer code from http://www.rabbitmq.com/tutorials/tutorial-one-java.html 
) that works fine from one machine, but not from another (both attempting 
to connect to the same broker/server). The machine that fails to run this 
successfully is in a completely different location, with its own firewall 
rules, so the first obvious thing to check is connectivity to tcp port 5672 
on the server machine, and I have confirmed (via both "telnet <hostname> 
5672" and via a simple java program that runs new Socket("<hostname>", 5672) ) 
that basic connectivity works fine.

My exception stack trace is shown below.

Any suggestions for next steps?
