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 "Bon-
       jour"). 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 frag-
       ments 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 infor-
              mation)

       --no-drop-root
              Don't drop root priviliges 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 informa-
       tion.

       /etc/avahi/services/*.service: static service definitions, see avahi.service(5) for more information.

SIGNALS
       SIGINT, SIGTERM, SIGQUIT: 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.
