NAME
       avahi-daemon - The Avahi mDNS/DNS-SD daemon

SYNOPSIS
       avahi-daemon [options]

       avahi-daemon --kill

       avahi-daemon --reload

       avahi-daemon --check

DESCRIPTION
       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	pro‐
       grams 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 pub‐
       lished via mDNS) and nss-mdns (a libc NSS plugin, providing name resolution via mDNS). Finally there is the D-Bus in‐
       terface 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.

OPTIONS
       -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

FILES
       /etc/avahi/avahi-daemon.conf: the default configuration file for avahi-daemon, avahi-daemon.conf(5) for more informa‐
       tion.

       /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.

SIGNALS
       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.
