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  uni‐
       cast  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  dae‐
              mon 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/re‐
       solv.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.
