avahi-autoipd(8)                                      System Manager's Manual                                      avahi-autoipd(8)

       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 auto‐
       matic IP address configuration from the link-local range without the need for a central server. It is primar‐
       ily 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  ad‐
       dress 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 http://developer.apple.com/qa/qa2004/qa1357.html for more information.

       -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 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 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.

       /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)
