spotifyd is listening to UDP port 5353 and replying to mDNS requests

Open stuart12 opened this issue 3 years ago • 0 comments

Description

Spotifyd is listening to UDP port 5353 and appears to be replying to mDNS requests, This breaks avahi-daemon.service on my Debian machine

To Reproduce

  1. watch the avahi-daemon.service logs with journalctl -fu avahi-daemon.service
  2. Start spotifyd
  3. See: avahi-daemon[1866]: Host name conflict, retrying with entrance-2

The problem became worse when I started running docker. Spotifyd is now advertising 172.17.0.1 (the address of the docker0 interface) in addition to the correct IP address. Every second lookup of entrance.local (my machine is called entrance) now gets the incorrect address 172.17.0.1.

Expected behavior

Spotifyd does not listen to UDP port 5353, Spotifyd does not reply to mdns requests.
