Yeah, but what's chroot jail? I read some docs here and there, but the practical concept and application is over my head. Is it a relevant security function in 2013 on a modern Debian like Ubuntu/Precise?
At any rate, I too was able to get port 80 rolling by simply tweaking <changeowner> to icecast2/icecast and changing /etc/default/icecast2 over to root. <chroot> is still "0". Have I just opened the barn door? ~:>3:-O
no, with changeowner available, you haven't opened the barn door :-t but nothing is really secure... you can close others open ports, services, etc really chroot icecast (search on google for tutorials)
