after upgrade some servers with the 2.0 all working fine (but in fact no ;) on one machine and with no apparently indications.. new stream (internal and external) can't be created and the web interface say : "getting information.." only the stream created on 1.9.5 is recognized ...
I've a problem too with stream configuration. Airtime cannot identify on Icecast2. An error 401 always displays.
My /etc/icecast2icecast.xml contains user ID and password of this old version. This id (and these of admin) don't match... So I don't be able to stream !
I'va forgotten that i've never set the ID for the user... It's set by default in the icecast2.xml at "source" So I just set the "source" ID and my right password !
