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.
