On feisty it’s probably a problem with using two different multicast daemons. I’d guess that feisty is probably using avahi, and you may be using a different one on your workstation.
How did you compile it, or where did you get the package from?
I did:
>apt-get install mt-daapd
it installed just fine, I could log into the web-page but the service didn’t show up in iTunes. After some searching here I restarted the avahi-daemon and mt-daapd started showing up in iTunes. It seems to work as long as I play music, but when its not used it disappears after a while.
How do I know if I’m running multiple multicast daemons?
