 |
|
Hi guys,
I am using Icecast (very successfully) on Debian Etch Systems.
Now I had the idea to run Icecast on port 80, so listeners behind firewalls or on mobile phones will have no problems receiving the program.
But: On Debian only root ist allowed to open Port 80 (I think every port less 1024 needs root to open), so Icecast errors "Error opening socket".
Any ideas? I dont want to use tools like rinetd...
Thank you!
Regards, Kai |

The general unix approach is to start as root (so that the bind will work) and then drop privileges to become the user specified in <changeowner>. There are other possibilities that you could look into like giving certain capabilities to the icecast process but those tend to be system specific.

Assuming the general approach, start icecast as root with an icecast xml that has a changeowner set to some non-root user/group

great! it works....
How to do it:
Edit: /etc/default/icecast2 and set user/group to root
Edit: /etc/icecast2/icecast.xml and uncomment changeowner.
Restart!
Done.
