`man 5 xinetd.conf` seems to imply that it listens on all interfaces by default... thoughts?

    bind    Allows a service to be bound to a specific interface on the machine.  This means you can have a   
    telnet server listening on a local, secured interface, and not on the external interface.  Or one port on one 
    interface can do something,  while  the same port on a different interface can do something completely 
    different.  Syntax: bind = (ip address of interface).
