I'm a newbie to networking but I do know that nmap is no toy. My
question is if I ...

nmap -sT localhost

....like
'http://en.wikibooks.org/wiki/Reverse_Engineering/Port_Scanners' says
would I be only seeing open ports on my own machine and could this be
done while my computer is a stand alone work station. I did look up the
meaning of localhost and it seemed like it was your own workstation but
I wanted to be sure.

Thanx.
