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 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) and 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, see 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.
