How to open a port with backtrack 4

[netxwis]

HI!
i want to check my network and using backtrack 4 these days...
i use metasploits, but i do not know how to open my ports.
there are three computers in my house, two of them are mine and the other one is my mother's.
i want to go into one of my computer by using the other computer.
i know how to check ip addresses and already checked opened ports.
Unfortunately (or fortunately shall i say?), there are no opened ports.

we can not go into the computer whose ports are closed, cant we?
if someone knows how to open ports with backtrack, please tell me :\
i had been trying to open them using the site called PORTFORWARD, but failed because i forgot (dont know) what the user name and the password are...

NOTE: im not thinking about doing something illegal!!!

You want to "check [your] network", but you don't know how to "go into one of my computer" (sic)? You're attempting to run before you can crawl. Actually, it's more like you're trying to drive an F1 car before learning to crawl. All you're going to do is crash and burn.

Go to a site that supports learning the basics of Linux, and learn how Linux functions. You would be best served by learning on a distro designed for beginners. Then, once you know the basics, come back to Back|Track if you still want to learn about security issues and how to check for them.

As well as Thorns suggestion above of brushing up on your Linux knowledge Id also suggest you read up on TCP/IP networking. You will have a very hard time trying to use BackTrack effectively for the type of thing you are trying to do without this. This will also give you a better conceptual understanding of what you are trying to do...
