root at mf-01:~# telnet
telnet> open mf-02 5672

AMQP    Connection closed by foreign host.

telnet works…

whats the directory / file path for the erlang cookie?

Running the following doesn’t really say much..

root at mf-01:~# rabbitmqctl status
Status of node 'rabbit at mf-01' ...
                        {os_mon,"CPO  CXC 138 46","2.2.7"},
                        {sasl,"SASL  CXC 138 11","2.1.10"},
                        {mnesia,"MNESIA  CXC 138 12","4.5"},
                        {stdlib,"ERTS  CXC 138 10","1.17.5"},
                        {kernel,"ERTS  CXC 138 10","2.14.5"}]},
{nodes,[{disc,['rabbit at mf-01']}]},
{running_nodes,['rabbit at mf-01']}]

Ok thanks for checking. When you say you can communicate between machines, can you explicitly telnet onto the port on which epmd is running? I'm assuming not (as it isn't listening). Is it very silly of me not to have asked this, but are the $HOME/.erlang.cookie files on all machines identical? Running rabbitmqctl status should show exactly the same cookie hash on each machine.
