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

[Steve Leibman]

Update: these same observations are true even if I point my clients to 
dev.rabbitmq.com.
I can connect to 5672 on dev.rabbitmq.com from either machine (e.g. using 
telnet), but my rabbit client fails from one of the two machines with the 
exception shown previously.
