     NAME
          avahi-autoipd - IPv4LL network address configuration daemon

     SYNOPSIS
          avahi-autoipd [options] interface

          avahi-autoipd --kill interface

          avahi-autoipd --refresh interface

          avahi-autoipd --check interface

     DESCRIPTION
          avahi-autoipd implements IPv4LL, "Dynamic Configuration of
          IPv4 Link-Local Addresses" (IETF RFC3927), a protocol for
          automatic IP address configuration from the link-local
          169.254.0.0/16 range without the need for a central server.
          It is primarily intended to be used in ad-hoc networks which
          lack a DHCP server.

          IPv4LL is part of the Zeroconf stack.

          avahi-autoipd can be used as stand-alone address allocator
          or as plugin for a DHCP client such as ISC's dhclient, where
          it can be used as fallback solution if no DHCP server is
          found.

          To allow communication between hosts that have only an
          IPv4LL address assigned and hosts that only have a routable
          IP address assigned you may add the following routes to both
          network configurations:

          route add -net 169.254.0.0 netmask 255.255.0.0 dev eth0
          metric 99

          route add default dev eth0 metric 99

          See http://developer.apple.com/qa/qa2004/qa1357.html for
          more information.

     OPTIONS
          -D | --daemonize
               Daemonize after startup. Implies --syslog.

          -k | --kill
               Kill an already running avahi-autoipd on the specified
               network interface. (Equivalent to sending a SIGTERM)

          -r | --refresh

     avahi-autoipd(8)             (User)              avahi-autoipd(8)

               Tell an already running avahi-autoipd to re-announce
               the acquired IP address on the specified network
               interface. (Equivalent to sending a SIGHUP)

          -c | --check
               Return 0 as return code if avahi-autoipd is already
               running for the specified network interface.

          -s | --syslog
               Log to syslog instead of STDERR. Implied by --
               daemonize.

          --debug
               Enable verbose mode.

          --no-drop-root
               Don't drop root privileges after startup. 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.

          -S | --start=
               Try to acquire the specified IP address, which must be
               from the IPv4LL range 169.254.0.0/16.

          -w | --wait
               Wait until a IP address has been successfully acquired
               before detaching. Only valid in combination with --
               daemonize.

          --force-bind
               Acquire an IPv4LL address, even if a routable address
               has been configured on the interface.

          --no-proc-title
               Don't change the process name while running. Unless
               this option is specified avahi-autoipd will reflect its
               current state and the IP address in the process title.

          -h | --help
               Show help.

          -v | --version
               Show version information.

     FILES
          /etc/avahi/avahi-autoipd.action: the script to run when an
          IP address as been acquired or is lost.

          SIGINT, SIGTERM: avahi-autoipd will shutdown. (Same as --
          kill)

          SIGHUP: avahi-autoipd will re-announce the acquired IP
          address. (Same as --refresh)
