Yahoo Messenger from behind a firewall

How to use Yahoo Messenger from behind a firewall (but with proxied access)

1.Download httptunnel (dont ask me just Google it) , compile and install on a *nix machine you have handy on the net somewhere (this is the tricky bit).

2. Set httptunnel up to forward from an "allowed out" port (eg https 443 or snews 563) to yahoo's servers (scs.yahoo.com port 5050) like so:

hts --forward-port scs.yahoo.com:5050 563

3. Set up your messenger client with the address & port of your server. ie your.machine.com port 563.

4. (optional) Firewall off the port so only you can connect to it
