       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
       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 netmask dev eth0 metric 99

       route add default dev eth0 metric 99

       -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.

              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 sucessfully 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.

       as been acquired or is lost.


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

       packaged and integrated into distributions.
