Introduction to Avahi

According to Avahi's site: Avahi is a system which facilitates service discovery on a local network. This means that you can plug your laptop or computer into a network and instantly be able to view other people who you can chat with, find printers to print to or find files being shared. This kind of technology is already found in Apple MacOS X (branded Rendezvous, Bonjour and sometimes Zeroconf) and is very convenient. Avahi is mainly based on Lennart Poettering's flexmdns mDNS implementation for Linux which has been discontinued in favour of Avahi.

Avahi Users/Groups

The avahi user is running the Avahi daemon: 

groupadd -g 20 avahi &&
useradd -c "Avahi Daemon User" -d /dev/null \
        -u 20 -g avahi -s /bin/false avahi

The avahi-autoipd user/group is for running the avahi-autoipd daemon: 

groupadd -g 21 avahi-autoipd &&
useradd -c "Avahi AutoIP Daemon User" -d /dev/null \
        -u 21 -g avahi-autoipd -s /bin/false avahi-autoipd

The netdev group is a priviliged access group for Avahi clients: 

groupadd -g 22 netdev

Configuring

Bootscript

There currently isn't a pre-written bootscript for avahi-autoipd and avahi-dnsconfd.

  • avahi-daemon - The Avahi mDNS/DNS-SD daemon.
  • avahi-autoipd - IPv4LL network address configuration daemon. For use in an ad-hoc network where there is a lack of a DHCP server.
  • avahi-dnsconfd - Unicast DNS server from mDNS/DNS-SD configuration daemon. Connects to a running avahi-daemon and runs the script /etc/avahi/dnsconfd.action for each unicast DNS server that is announced on the local LAN.
