If I do netstat -n and view all connections, then choose to close the programs using those ports, the connection should be terminated (the port closed).
Am I understanding this correctly?

I've noticed that KaZaA Lite shows established connections even after the program is closed (i.e. I close program then several minutes later do netstat -n and my results still show established connections on port 1214 with the IP's of people that had been uploading from me)

Two questions....Is this normal for this program? and is it anything to be overly cautious of/alert to?
