nss-mdns is a plugin for the GNU Name Service Switch (NSS)
functionality of the GNU C Library (glibc) which provides host
name resolution via Multicast DNS (a.k.a. Zeroconf, a.k.a. Apple
Rendezvous, a.k.a Apple Bonjour). This effectively allows name
resolution by common Unix/Linux programs in the ad-hoc mDNS domain
.local.

To test, the following command should return a mapping for the remote
host:

  getent hosts <hostname>.local
