Telnet into a computer(IP)
Search any IP for open ports
OK this is a guide on how go get anyones IP over msn.
Step 1
First go to:
Start > Run
and type in "cmd" or "command"
and hit enter
to open the command prompt
Step 2
Go on MSN and start talking to somebody(The one you want the IP from).
Go to the command prompt again and type in:
netstat -n
DO NOT HIT ENTER YET!
Step 3
Send a file or an image to the one you want the IP from.
Once they accept, go to the command prompt and hit "Enter"
Step 4
One or two line(s) in the command promp will then say something like:
TCP xxx.xxx.x.x:1337 xxx.xx.xx.xx:1234 NET_SENT
The second IP, The External adress is the IP of the remote computer.
Just scan that IP with Nmap and you know wich port is open. ;)
This may not work for everyone. But for most it will ^^
