You need to look at the settings on your firewall or router.

Ports aren't exactly open until a service opens them. Ports aren't actually sitting on your computer, waiting to be opened. They are virtual, and they aren't actually active until a service wants to use one. For example, port 21 on your computer will not be opened until you run an FTP server. The FTP server will want to use port 21, so the FTP server will begin listening on port 21, and your computer will direct all packets headed for port 21 to the FTP server. You can always check what ports are open on your computer by using "nmap". It's a great tool for port scanning (either your computer or other computers on a network). You can just check your own machine by typing "netstat -l". That will show you which ports are listening on your computer.
