An alternate port for MSN Messenger - via Trillian and/or Gaim?
Several months ago I setup Trillian on my XP box and Gaim on my Linux box, both at work. Our firewall does not allow the standard IM port traffic to pass, but that's OK since AIM, ICQ, and YIM all offer alternate ports for their clients. So I have Yahoo running on port 80, and AIM and ICQ both on port 20. Finding these ports simply meant installing the standard client and using their handy 'find an alternate port' feature, letting them connect, and then copying the port number. However, MSN Messenger lacks this feature. Oh, it seems to connect OK. My WinXP box's built in Windows Messenger is connected right now (with an account I created for work). But I can't find the settings. I tried Etherial, and I watched it connecting, but trying to copy the IP/port didn't work. But I know XP has Windows .NET Messenger and it is different from the 'standard' MSN Messenger all the non-XP platforms use, so that may be it. Google also failed to help.

So, anyone know of an alternate port to use with Trillian and/or Gaim to connect to the MSN Messenger service?

Avoid M$!

I think that is just the universe subtly hinting that you should avoid any of Micro$oft's crappy services all together. Just say no to MSMessenger, even if you can connect to it via another client (like GAIM or Everybuddy).

There's something tickling at the back of my mind that says that XP Messenger doesn't use a fixed port, but chooses them rather randomly.

Hmm, http://www.microsoft.com/technet/treeview/default.asp?url=/technet/prodtechnol/winxppro/deploy/worki01.asp
suggests this only applies if one wants to use audio/video. Try sniffing on two messenger connections (probably should reboot between them).

http://news.com.com/2100-1032_3-5066412.html?tag=fd_top may also apply, although that shouldn't have happened yet.

I can think of a couple ways around that problem, I'd probably go with just setting up a tunnel to somewhere you have a shell on an innocuous port and then bouncing through the tunnel to connect. If I'd caught this while I was at work I could've done some investigating for you, but I lack an XP machine here. It strikes me as kind of weird that your firewall blocks outgoing connections on high ports though. According to the minimal documentation I'm seeing, you should be able to use alternate ports, but it doesn't specify what. However, there is mention of the ability to wrap the entire connection in HTTP, using a different login server. Check out: http://www.hypothetic.org/docs/msn/general/http_connections.php
Looks kind of cumbersome, but it should be doable.

Dammit, that was me. LJ and/or Moz did something all funky and was showing me my friends page, but while logged in as her.
