Guys. Zach has created a hack which just reads the server status information, streams the song info, provides a link to listen to the stream and allows access the to stats. He really can't be expected to answer all the questions on configuring a shoutcast server. I guarantee if you are not seeing the server online then there is a port issue somewhere (doesn't matter if its on your own server - check your firewall).
Here are some useful links
Winamp SHOUTcast Forums
Radiotoolbox - Ensure you are the IP you think you are and do a port scan - if it fails you haven't configured your settings correctly. It's not the hack.
Portforward.com - Ensure you have set up port forwarding correctly for your router
Hope this helps.
