This is what the documentation says about node naming for the erl command:

"-sname Name
Makes the Erlang runtime system into a distributed node, similar to
-name, but the host name portion of the node name Name at Host will be
the short name, not fully qualified.

This is sometimes the only way to run distributed Erlang if the DNS
(Domain Name System) is not running. There can be no communication
between nodes running with the -sname flag and those running with the
-name flag, as node names must be unique in distributed Erlang
systems."

HTH,
