Question : Open Ports.

I want to know how would I be able to close open ports on my computer.
I performed a port scan of my pc, and found serveral open and unidentified ports. And am interested in closing some of them.

Also, is there a site that I could go look at a listing for all ports and see what uses what port?
I know of the services file in Windows, but as you all know it only lists registered ports.

I once heard of a site that gave you a comprehensive list of most of the TCP and UDP ports.

Answer : Open Ports.

once again, i'll recommend foundstone's fport utility.

it will tell you what executable or library is bound to what port...then you can make an assessment as to whether it's detrimental or not, or malicious or not.
