The wonders of multicast DNS

“Every release of Ubuntu is more like the Mac.” That’s what one of my coworkers said when I pointed out that you no longer need to pass around IP addresses for copying files from one workstation to another on the LAN. The machines announce themselves on the LAN by multicast DNS. This means that you can acccess other machines as hostname.local and It Just Works™.

And it’s not just Ubuntu, the service is provided by avahi-daemon and the name resolution works thanks to nss-mdns. Fedora and SuSE also have these pieces of software in the default configuration.

It’s strange how few people have noticed.
