WS Port Listener

Port Listener is a simple, smart and easy-to-use programthat runs in the system tray. When activated, it opens a port that you specified for monitoring, so you can check if a certain user connects to that port.
Port Listener will make a sound (if you specified one) when a user connects, it will also give the users ip host etc and will keep a log of all connects.
The program also keeps sending a text which you specified to the user until he disconects from that port so he knows he has been catched.
Port Listener is created to catch those guys that do portscans on your system for a specific port, for instance the trojan (a trojan is a kind of virus that lets user control your pc remotly) sub7 which mostly runs at port 27374, so you let the program monitor on that port.
Then when someone is doing portscans to see if you are infected by sub7 you will be alarmed of this and the user keeps getting the text you specified in his portscanner (like 7th sphere) until he closes or reset the portscanner. So the person who did the portscan will know he is caught
You can then check the log for the persons ip and host and with this information you can find out what provider there using and find their providers web site to sent them an email informing them of the person that does these portscans (give an extract of the log with the date and time ) and they will make sure the person will be notified of these illegal (in some countries portscanning is legal) actions.
