Unix systems don't allow non-root users to bind to ports less than
1024. So, you need to be root to do this.

When you try this, you'll then find that icecast refuses to run as
root (in an attempt to prevent any possible icecast security holes
from being _too_ serious).

So, you'll have to configure the <changeowner> section (inside
<security>) in your icecast configuration file.

This tells icecast to change to a different user (whichever one you
choose) after it binds listening sockets, but before it starts
accepting connections from the network.
