Avahi, Multicast DNS and Domains

This post is part of my project to create an automatic configuration package for the Avahi software on Pidora Linux. This post will detail my exploration into changing a domain on a Raspberry Pi. It will also deal with how to receive and advertise on a changed domain.

The hostname for Pidora 18 is not set in /etc/sysconfig/network but instead is set in /etc/hostname. This change did affect the hostname, but Avahi was still pulling the domain name from the /etc/avahi/avahi-daemon.conf file.

I have determined through testing that Avahi does not support traditional unicast DNS resolution. Avahi will only resolve the .local domain. As a result, work that deals with custom domain names will cease. I will now move onto adding nss-mdns and host resolution into the nsswitch.conf file.
