[Icecast] relay icecast to shoutcast

[Iain D Mott]

Hello List

Having great trouble relaying an icecast2 mp3 stream to a shoutcast server.
My client program successfully streams to icecast which is listening on
port 7000. I can listen to this stream with mozilla and xmms with no
problems. I can also stream my client directly to the shoutcast server but
it makes the client unstable (which is why i'm attempting a relay).

The shoutcast server is set up to relay with the relay host as: 
beijing.zhongshuo.org and port: 7000. The mountpoint my client sets is
“radio”.

I'll paste below my icecast.xml page. I've tried various port permutations
and aliasing but I can't get anything to work. (xmms reports a “402
Service Unavailable”)

Hope someone can help.

Cheers, iain
