Incoming requests to epmd use port 4369. Until recently the subsequent
connection to the node used a random port but there is now the possibility
to configure the ports using some kernel parameters - inet_dist_listen_min
and inet_dist_listen_max.

e.g. erl -name sean -kernel inet_dist_listen_min 4711 inet_dist_listen_max
4720 will allow you to have 10 nodes listening.
