Open Ports

I was wondering if there is an online site that can tell you what ports are not being blocked on a network PC. Sites like Sygate's tell you about the obvious ones like FTP and Telnet ports, but what about those not mentioned on these tests? Is there a way to scan yourself for an open port? :confused:

If you have another internet connection (even dialup) you can use a tool like NMap to do a full scan yourself. I believe www.dslreports.com does full scans , why don't you just check them out.
Edit- Look under tools for the scans.

You can always try this link:

And this one: http://www.blackcode.com/scan/

NMap is one of the better, more well-known ones: http://www.insecure.org/

can NMAP work on windows? i thought it was strictly *nix :(

they have a port for windows. the last time i checked they only had the win source code for download but theirs a few places around where you can download the binary

nmap is great, but u can also actualy spend time to portscan your computer with a portscanner......... it works well and u can elt it go to as high of a number as you want
