avahi-daemon(8)                                       System Manager's Manual                                       avahi-daemon(8)

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 exclu‐
       sively 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.
