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

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 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 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 informa‐
       tion.

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 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.

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

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