34 <p>The Avahi mDNS/DNS-SD daemon implements Apple's Zeroconf
35 architecture (also known as "Rendezvous" or "Bonjour"). The daemon
36 registers local IP addresses and static services using
37 mDNS/DNS-SD and provides two IPC APIs for local programs to make
38 use of the mDNS record cache the avahi-daemon maintains. First
39 there is the so called "simple protocol" which is used
40 exclusively by avahi-dnsconfd (a daemon which configures unicast
41 DNS servers using server info published via mDNS) and nss-mdns
42 (a libc NSS plugin, providing name resolution via mDNS). Finally
43 there is the D-Bus interface which provides a rich object
44 oriented interface to D-Bus enabled applications.</p>
46 <p>Upon startup avahi-daemon interprets its configuration file
47 <file>@pkgsysconfdir@/avahi-daemon.conf</file> and reads XML
48 fragments from <file>@servicedir@/*.service</file> which may
49 define static DNS-SD services. If you enable
50 <opt>publish-resolv-conf-dns-servers</opt> in
51 <file>avahi-daemon.conf</file> the file
52 <file>/etc/resolv.conf</file> will be read, too.</p>
