avahi-daemon - The Avahi mDNS/DNS-SD daemon
avahi-daemon [options] avahi-daemon --kill avahi-daemon --reload avahi-daemon --check
The Avahi mDNS/DNS-SD daemon implements Apple's Zeroconf architecture (also known as "Rendezvous" or "Bonjour"). The daemon registers local IP addresses and static services using mDNS/DNS-SD and provides two IPC APIs for local programs to make use of the mDNS record cache the avahi- daemon maintains. First there is the so called "simple protocol" which is used exclusively by avahi-dnsconfd (a daemon which configures unicast DNS servers using server info published via mDNS) and nss-mdns (a libc NSS plugin, providing name resolution via mDNS). Finally there is the D-Bus interface which provides a rich object oriented interface to D-Bus enabled applications. Upon startup avahi-daemon interprets its configuration file /etc/avahi/avahi-daemon.conf and reads XML fragments from /etc/avahi/services/*.service which may define static DNS-SD services. If you enable publish-resolv-conf-dns-servers in avahi-daemon.conf the file /etc/resolv.conf will be read, too.
-f | --file= FILE Specify the configuration file to read. (default: /etc/avahi/avahi-daemon.conf) -D | --daemonize Daemonize after startup. Implies --syslog. -s | --syslog Log to syslog instead of STDERR. Implied by --daemonize. --debug Increase verbosity to debug level. --no-rlimits Don't enforce resource limits as specified in the configuration file. (See setrlimit(2) for more information) --no-drop-root Don't drop root privileges after startup and don't require daemon to be started as root. We recommend not to use this option. --no-chroot Don't chroot(2) the daemon. This option is only available when compiled with chroot() support. --no-proc-title Don't change the process name while running. Unless this option is specified avahi-daemon will reflect its current state and the selected host name in the process title. -k | --kill Kill an already running avahi-daemon. (equivalent to sending a SIGTERM) -r | --reload Tell an already running avahi-daemon to reread /etc/resolv.conf (in case you enabled publish-resolv-conf-dns-servers in avahi- daemon.conf) the files from /etc/avahi/services/. Please note that this will not reload the /etc/avahi/avahi-daemon.conf. (equivalent to sending a SIGHUP) -c | --check Return 0 as return code when avahi-daemon is already running. -h | --help Show help -v | --version Show version information
/etc/avahi/avahi-daemon.conf: the default configuration file for avahi- daemon, avahi-daemon.conf(5) for more information. /etc/avahi/hosts: additional static hostname mappings to publish in mDNS, see avahi.hosts(5) for more information. /etc/avahi/services/*.service: static service definitions, see avahi.service(5) for more information.
SIGINT, SIGTERM: avahi-daemon will shutdown. (Same as --kill). SIGHUP: avahi-daemon will reload unicast DNS server data from /etc/resolv.conf and static service definitions from /etc/avahi/services/. (Same as --reload) SIGUSR1: avahi-daemon will dump local and remote cached resource record data to syslog.
