    Try using nmap. If you don't already have it installed, you can download and install fyodor's nmap program from here. Note: I get an error about not having the GUI capabilities or something like that when making the project. This is really a warning, not an error. The program can run in terminal mode just fine.

    Oops, my bad ... totally forgot about good ol' netstat. Actually nmap is handy, if you want to scan other machines to check for open ports.

    Also, after you have nmap installed try a program called Nessus, I suggest using the GUI as you have a little more power with it. Nessus uses nmap for its port scan function, but it also checks overall security. It uses a builtin set of attacks, and exploits that it uses. New exploits can also be downloaded for it. This can be used to check a whole network's vulnerability, though you may want to turn off the fatal attacks, especially if you have NT boxes =) .. Good luck ..
