I've been trying to get the transparent proxying facility of icecast to
work so I can listen to multiple copies of stream on my local network,
while only receiving a single stream over my WAN link (Like DUH! thats
what the proxy is for ... I know, stay with me). I have mpt been been
able to get this feature to work, and it looks like there may be a bug
in the icecast server as everytime I try to connect to icecast as a
proxy it becomes really unstable and locks up whenever I try to execute
alot of commannds from the console (like sources, listeners) or
shutdown. Whenever I try to connect with winamp configured with my
icecast server as proxy - the first time the proxy ->
goes of and gets the stream eg.
-> [17/May/2001:20:02:15] Accepted encoder on mountpoint
205.188.234.34:8002/ from lsac1-0-s02.shoutcast.net. 1 sources connecte
But the stream doesn't get transferred to winamp. if I try to connect
again icecast keeps spawning more connection handler threads but I can
get no streams from it and it becomes unstable as descibed above, eg
here the output of threads after attempting 5 connections to the icecast
proxy from Winamp.

I have tested this on my Redhat linux (i386) 7.0 server with 2.4.x
kernel at home, and my Redhat linux 7.0 with standard 2.2.16-22 kernal
at work with the same problems.
I beleive I have setup the configuration file correctly, setting
transparent_proxy to 1 and configuring the server_name directive to a
valid DNS hostname on my home machine, and a valid static IP on my work
machine. I am using icecast 1.3.10, have tried both the rpm's, compiling
from the source distribution and compiling the latest cvs code with the
same results. I use Winamp for windows (latest 2.x ver) to test the
proxy functionality. I have tried Freeamp for linux for testing, but
can't get icecast to respond at all when using the proxy feature. I
can't find any proxy setting on xmms to use that for testing.
If anyone has got the transparent proxy feature work, I would love to
know about it, and if you could send your configuration file to me (and
maybe the plaform/setup info) at graeme@gloptum.com I would greatly
appreciate it. Otherwise any other info would be greatly appreciated.
Regards,
Graeme
