Which TCP port does Erlang use for connecting to a remote node?

Question

I need to open a firewall port so that I can connect from one Erlang node to another. Is there a standard port?

You can limit the TCP ports used by Erlang to a specified interval using the following kernel app. parameters:

erl -kernel inet_dist_listen_min 9001 inet_dist_listen_max 9005

You also need to enable the 4369 TCP port, as it is used by epmd. (This port can also be changed by the ERL_EPMD_PORT environment variable.)
