Hello, and a good day to you all.  I run a couple slackware 9.1 boxes where
I work for our Internet related services.  I like to use nmap to make
sure I am running only the services I need.  While nmap'n both these
boxes today I noticed something I have not seen before.  All of a
sudden both boxes are listing this:

Port        State      Service
1720/tcp    filtered   H.323/Q.931
also
690/tcp     open       unknown  # this has also appeared on one of
                                # boxes.

I'm kinda concerned.  I have not introduced, or turned on any new
service.  I did upgrade the kernel on both boxes to 2.4.24 since I last ran nmap I
think.  Could the new kernel be doing something with this port 1720?
Or perhaps, someone it exploiting my machines?  Hope not.
I can't figure out the 690 port either.

here are the ip's of the boxes in question
64.122.144.195
64.122.144.196

Any thoughts would be greatly appreciated to help solve my mystery.

Many Thanks,
