Telnet into a computer(IP)
Find an IP over MSN
This is a guide to check any IP for open ports useing
Nmap.
Step 1
After installing Nmap, Open Nmap GUI(Zenmap)
NOTE: If you are one windows Vista you may have to run as administrator to be able to connect to the IP.
Step 2
Type in the IP you want to scan like shown here:
I use the IP "127.0.0.1"
Type in the IP and choose "Intense Scan" and hit "Scan"
Step 3
When the scan is finished, look down the Output box for e green line saying something like:
443/tcp open ssl OpenSSL
Any port in a green text will do (Doesn't matter what the text says :P) ;)
And there you got it. The port on the line in green is an open port :)
