197503 2003-12-05 02:30:00 How do you find out someone elses IP? Say if I was talking to the person on Windows Messenger. I take it I would type netstat -n to display all current connections, but how would I distinguish which one is that person? Craig (448)
197504 2003-12-05 02:35:00 AFAIK, All the connections for MSN Protocol v9 (and previous) go through a server, so chances are it'll show the connection to that..

ICQ _can_ do it, but apparently it does something like File-transfers directly, and chats through server (by default - I know the likes of Licq can be set to directly send the chat).

Craig: Hey dude, do you mind telling me your IP address?
Other Person: Oh yeah it's this X.X.X.X

[/excerpt of Craig's MSN Conversation]

If they're not wanting to tell you their IP address you don't need to know it ;-)

197506 2003-12-05 13:48:00 One might question why you'd want to know their IP address.

And yeah, netstat will show you the connects to a server, but won't show you the IP to a user on the other side.

197507 2003-12-05 15:25:00 Initiate a file transfer with the person. Send him something supposedly funny or something (social engineering).

Look in the firewall logs and look for an entry that is about the size of the picture file, and note the time it occurred. Or do a netstat as the file is transferring.

The filesharing is done directly (Peer to peer).

197508 2003-12-05 18:31:00 Windows Messenger chat messages are relayed through the Microsoft MSN Servers to help give privacy to the person you're talking to - which is why 'netstat' only shows connections to *.messenger.microsoft.com. About 2 months ago Microsoft realized that File Transfers did direct transfers (eg: one person to another) therefore I could send you a piccy of my desktop and 'netstat' would display your IP Address, since then (AFAIK) Microsoft have been relaying all file transfers through their servers to help masquerade the IP Address of both parties.
I'm guessing that the same thing happens for Voice and/or Video convo's.

197509 2003-12-05 21:37:00 Couldn't you then do 'netstat' to find the microsoft connection, and 'tracert' to find the person on the other end of it? Craig (448)
197510 2003-12-05 22:18:00 All tracert will give you is the route it took to get to the MSN server :) Pheonix (280)
197511 2003-12-05 22:20:00 Surely its possible to find a remote computers IP, why does no one know how. Craig (448)

Why are you so keen to find out people's IP addys? If the person you are chatting to does not want to give you their IP address then you have no business getting your hands on it.
