     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
          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.

     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

     avahi-daemon(8)              (User)               avahi-daemon(8)

               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 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.
