Is the existing rabbit running with the same Erlang cookie as the new 
one? The cookie hash produced by rabbitmqctl is for the current node, 
not the one you're attempting to contact.

The list of nodes/ports on the given host indicates which Erlang nodes 
are up, but not necessarily whether they're allowed to connect to or 
not. Check your cookie and let us know how you get on.
