Thanks everyone for your responses.


i did go to grc.com and although i have many ports open - it reads them
as stealth which according to the site it's a good thing. Would anyone
know what stealth indicates? The ports which were open and not stealth
were 21, 80, 110.

Here are a few ports which are open:

32768
1025
98
995
389
32774
9128
9130
3306
10443


How do i tell who's using what? And is it important?

Thanks again,

2003 AD

Also, i do see all the ports which are open but in order to close them
(correct me if i'm wrong) is to disable the service, no? If this is so,
how do i match the port to the service? There are way too many!
