[Icecast] Icecast authentication cant resolve address on Debian

[Martin Harrison]

Hi,

I am trying to use the url authentication method but am having trouble
getting icecast to work on a Debian installation on a VPS platform.

I have logged in my VPS as root and installed icecast using

apt-get install icecast2
setup the config file and then set ENABLE=true in /etc/init.d/icecast2

This initialy didn't work as it couldn't access log files and then had
trouble with the graphics on the admin pages.
I fixed this by copying the graphics from /usr/share/icecast2/web into
/etc/icecast/web and by changing the log/web/admin paths
from /var/log/icecast to /log and /usr/share/icecast2/web to /web.
I also had to change the base dir fromto /usr/share/icecast2 to
/etc/icecast as none of the linked xmls files could be read.

At this point icecast will run, display the admin pages correctly, allow a
source to conenct and users can listen.

However when I enable the authentication it fails to resolve the address
for the authentication script. The log files contain just two warnings
that I don't understand the implications of/can't resolve.

[2011-06-03  16:47:46] WARN stats/stats_event_conv No charset found for

http://www.***.co.uk/online/auth.php failed with Couldn't resolve host
'www.***.co.uk'

running curl from the icecast2 account created during the installation
works just fine returning

I am assuing that this is something to do with access rights but am no
unix expert (I developed my authentication system with icecast on a
windows box trouble free).

The relevant sections of the config file are below. any help is really
appreciated.
