       avahi-autoipd - IPv4LL network address configuration daemon

       avahi-autoipd [options] interface

       avahi-autoipd --kill interface

       avahi-autoipd --refresh interface

       avahi-autoipd --check interface

       avahi-autoipd  implements  IPv4LL, "Dynamic Configuration of IPv4 Link-
       Local Addresses"	(IETF RFC3927),	a protocol for	automatic  IP  address
       configuration from the link-local	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 fall-
       back 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 netmask dev eth0 metric 99

       route add default dev eth0 metric 99

       See for more informa-

       -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 re-announce the ac-
	      quired IP	address	on the specified network  interface.  (Equiva-
	      lent 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.

	      Enable verbose mode.

	      Don't drop root privileges after startup.	We  recommend  not  to
	      use this option.

	      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

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

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

	      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.

       /home/lennart/tmp/avahi/usr/local/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)

       The  Avahi  Developers  <avahi (at) lists (dot) freedesktop (dot) org>;
       Avahi is	available from

       autoipd.action(8), dhclient(8) documents how	avahi-autoipd is  best
       packaged	and integrated into distributions.
