I have fooled with this a little. This is a polite service. You allow this
service on your host if you want to let the remote host know who you are. It
is useful if you were to only allow "polite" hosts access. In other words,
you could mandate that all connections made to your host will be validated
if they support service 113. And you would do the "polite" thing by
instituting 113 on your host. Good for finding out who is logging not only
just what host.
