Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Have you tried putting the port numbers into google to see what comes up?
I just put "port 3130" in and got 3 pages of hits.
I'll freely admit that the 2 or 3 links that I looked at didn't help much, but that's hardly suprising, seeing as my Linux/IT knowledge could be written on the back of a very small postage stamp
Seriously though, I don't mean to sound patronising/condescending, because it's taken me forever to get into the habit of googling for something first, well at least after I've searched here, before asking a question - it saves a fair amount of repetition.
You might just want to see what happens when you close the ports i.e. see if something doesn't work in your system, if it's something essential, then re-open, if not leave it closed.
Is there a nice simple command for closing and opening a specific port? I've tried looking through various firewall scripts but i really have no idea what is going on in them.

As far as I can tell, is a port associated with named. It is not always the same port number, and changes with each stop/start of named. Had me freaked out until I did what spank did and killed everything that was running until an nmap showed it gone. Killing named made it go away.
