Avahi mDNS/DNS-SD daemon Avahi is a fully LGPL framework for Multicast DNS Service Discovery. It allows programs to publish and discover services and hosts running on a local network with no specific configuration. For example you can plug into a network and instantly find printers to print to, files to look at and people to talk to. This package contains the Avahi Daemon which represents your machine on the network and allows other applications to publish and resolve mDNS/DNS-SD records.
