I have noticed a few servers (included mine) lately with port 4 open.
somone know what this port is for?


Anybody searching for a port number should start with
http://www.isi.edu/in-notes/iana/assignments/port-numbers.  Mind you,
according to that list, port 4 is unassigned.  Find out which program
has it open, use lsof or a similar tool.
