Install And Configure The Avahi Service

Run the following two commands.
Gentoo:
# echo "net-dns/avahi -gdbm -introspection" >> /etc/portage/package.use
# emerge avahi
The first command tells portage (Gentoo's package management system) to build avahi without support for gdbm and introspection. These two features are not required and would cause portage to pull in several more uncessary packages when building avhai.
The second command tells portage to download, compile, and install the avahi service.


Red Hat / CentOS:
# yum install avahi
Debian / Ubuntu:
# apt-get install avahi-daemon


Edit the avahi configuration file and make the following changes:
All Distributions
/etc/avahi/avahi-daemon.conf

...the rest of this config file should be left unchanged...

allow-interfaces=vlan10,vlan20,vlan100,vlan101
# Notice that vlan5 is not included. In this demonstration, there is no
# reason to listen for, nor re-broadcast mDNS traffic onto the Servers
# subnet because there will never be an Apple mobile device, nor an AppleTV
# on the Servers subnet

enable-reflector=yes
# This line is the key. It tells the avahi-daemon process to listen for
# mDNS traffic on all of the allowed-interfaces defined above and then 
# re-broadcast any mDNS traffic that it hears onto all of the other 
# allowed interfaces


Start the avahi-daemon service and configure it to start on boot:
Gentoo
# rc-service avahi-daemon start
# rc-update add avahi-daemon default
Red Hat / CentOS:
# service avahi-daemon start
# chkconfig --add avahi-daemon
Ubuntu / Debian:
# service avahi-daemon start
# update-rc.d avahi-daemon defaults
