I have a LMS installation at home and a shoutcast music stream public-ally available. Sometimes I want to join some friends online and allow them to queue music up from my LMS into the shoutcast stream.
I use darkice to stream what I'm listening to up to a shoutcast server. And then I forward the http of my LMS install to an intermediary host with this command:
ssh -R 8081:localhost:9000 -p 23 richard@my-intermediary-host.com
Then, on my-intermediary-host, I set up an apache proxy, and add in basic http auth to stop folks chancing apon it.
Listen 8008
<VirtualHost *:8008>
ProxyPreserveHost On
# Servers to proxy the connection, or;
# List of application servers:
# Usage:
# ProxyPass / http://[IP Addr.]:[port]/
# ProxyPassReverse / http://[IP Addr.]:[port]/
# Example:
ProxyPass / http://0.0.0.0:8081/
ProxyPassReverse / http://0.0.0.0:8081/
<Proxy *>
Order deny,allow
Allow from all
Authtype Basic
Authname "Password Required"
AuthUserFile /etc/httpd/.htpasswd
Require valid-user
</Proxy>
</VirtualHost>
The next step here is to avoid using darkice and probably use LMS's mp3 streaming output to plug directly into shoutcast... probably using ssh forwarding for that as well.
