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
          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.

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.
