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
              Tell an already running avahi-autoipd to reannounce 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 priviliges 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 sucessfully 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 it's 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.

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

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