Yesterday in the late evening I commited “Wide Area” support to Avahi (http://www.freedesktop.org/Software/Avahi) SVN, i.e. “DNS-SD over Unicast DNS”. Only browsing, no “Long-Lived Query” support and no publishing for now, but it is a start.

To show off how cool this is, here is a “screenshot” of avahi-browse showing all services defined in the domain 0pointer.de:

$ avahi-browse -a -d 0pointer.de Browsing domain ‘0pointer.de’ on any.-1 … Browsing for services of type ‘_http-rss091._tcp’ (Web Syndication RSS 0.91) in domain ‘0pointer.de’ on any.-1 … Browsing for services of type ‘_http-rss20._tcp’ (Web Syndication RSS 2.0) in domain ‘0pointer.de’ on any.-1 … Browsing for services of type ‘_http._tcp’ (Web Site) in domain ‘0pointer.de’ on any.-1 … Found service ‘Lennart’s Blog’ of type ‘_http-rss091._tcp’ (Web Syndication RSS 0.91) in domain ‘0pointer.de’ on any.-1.
