[erlang-questions] Interconnect question: how to work with names

[Dániel Szoboszlay]

The host part of the node name has to match, otherwise the master node
would believe the debug node is trying to connect to someone else and would
refuse the connection.

Try this command instead:
erl -name debug -remsh master@$(hostname)
