This is a quick set-up guide on how to install Icecast for Mp3 and Ogg streaming, sort of online radio. Tested on Debian Wheezy. Probably works on Ubuntu, etc. Icecast is a "server-like". It offers the HTTP URL/port through which end-users can play the media. However, Icecast itself does not serve the files. It must get its input from other "client-like" software. For example, Ices0 sends mp3 input to Icecast and then Icecast delivers to the end user. Similarly, Ices2 sends ogg input to Icecast and then Icecast delivers to the end user.
Start by installing:
sudo apt-get install icecast2
