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> 45 46 <p>Upon startup avahi-daemon interprets its configuration file 47 <file>@pkgsysconfdir (a] /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> 53 </description> 54 55 <options> 56 57 <option> 58 <p><opt>-f | --file=</opt> <arg>FILE</arg></p> 59 <optdesc><p>Specify the configuration file to read.
