Enabling Multi-cast DNS on Fedora

I routinely forget how to do this, so I figured I would record it here
in so I have an easy place to find it in the future.

Fedora has almost everything needed to use mDNS. There are only two
simple steps needed to completed installation and configuration of Avahi
for mDNS.

  1. Install nss-mdns from the main Fedora repository:
sudo yum install nss-mdns
  1. Open the mDNS port on the firewall:

That’s it. Once these two steps are completed, you should be able to
ping your system using the name [hostname].local and other systems
using mDNS will be able to discover your system on the network.
