There are many of them around the net that will scan your machine and report the ports that are open or viewable from their end. DSLReports is one,
as mentioned. Another good one to use is Gibson's Site.
It allows you to do a few different types of scans against yourself and then it reports back the open ports, tells you a little about them, and how to
**There are few places that will actually Scan Every Port Possible as that takes some time. Most go up to atleast 10,000 or so. There are 65535
ports possible in total though.**
To Scan yourself Using Your own computer, I would recommend something like superscan. It's powerful but easy and fast and best of all free and runs
without needing to be installed. www.snapfiles.com...
There are more Stealthy Scanners out there like NMap and UDP Port Scanners and stuff too, but I'm not going to get into all that right now.
A quick and easy command you can use at the System Prompt to see you current Connections and/or Netword Ports being used is "netstat". Use
"Netstat -n" to show IP addresses instead of Hostnames. Use "Netstat -a" to show ALL Ports being Used Connected or Not Connected. (For Example:
Syn, Fin, waiting states, and UDP Ports along with the basic "TCP Port Traffic in the Connected state".
