Now and then paranoia sets and im sure big brother or some hacker is looking at my PC so now and then i check the Netstat command from the *Dos* prompt. Netstat (if you don't know) is a command tool to display active connections your PC currently has, both incoming and outgoing. But it does have its other users as well like i've just found out i've set Apache to listen of a couple of extra ports i forgot about. If you do want to run it you'll see the information restrictive so run the following
netstat -abThe gives you some extra info per connection i.e.
-a Displays all connections and the listening ports
-b Displays the exec involved with the connection
