The hostname resolution via Multicast DNS (using Zeroconf, aka Apple
Bonjour / Apple Rendezvous) which effectively allows name resolution by
common Unix/Linux programs in the ad-hoc mDNS domain "local", can be
provided by installing the libnss-mdns package. The "/etc/nsswitch.conf"
file should have stanza like "hosts: files mdns4_minimal
[NOTFOUND=return] dns mdns4" to enable this functionality.
