I have a problem with the icecast. When I activate the service I am having<br>
an exesive consumption in the ip queries. It seems like a DDOS attack. How<br>
can I mitigate this attack?<br>

Why do you think it's a DDOS?  What do you see?<br>
<br>
If it's an option, try running it on another port.<br>
