The Avahi mDNS/DNS-SD daemon implements Apple's Zeroconf architecture (also known as "Rendezvous" or "Bonjour").

Tips

After installing avahi-daemon it may not start. To fix this you may need to run service messagebus start

Service types are defined in /usr/share/avahi/service-types

Service configs

Correctly formatted and named files in /etc/avahi/services/whatever.service are loaded on the fly, no need to restart avahi-daemon. If your service doesn't immediately show up, check syslog for errors.
