$ ssh remote-host "epmd -names"
epmd: up and running on port 4369 with data:
name some_node at port 58769
Note the running on port for epmd itself and the port of the node you're interested in debugging. Reconnect to the remote host with these ports forwarded:
$ ssh -L 4369:localhost:4369 -L 58769:localhost:58769 remote-host
