If you want to connect to your rabbit node via the Erlang REPL then you can start another node in the REPL like this -

 erl -sname test -setcookie "ERLANGCOOKIE"

then try -

net_adm:ping('rabbit@hostname').

If it returns 'pong' then you're in business, but if you see 'pang' returned then you have not managed to reach your rabbit node.
