|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:
|\fBroute add -net 169.254.0.0 netmask 255.255.0.0 dev eth0 metric 99\f1
|\fBroute add default dev eth0 metric 99\f1
|See http://developer.apple.com/qa/qa2004/qa1357.html for more information.
|\fB-D | --daemonize\f1
|Daemonize after startup. Implies \fB--syslog\f1.
|\fB-k | --kill\f1
|Kill an already running avahi-autoipd on the specified network interface. (Equivalent to sending a SIGTERM)
|\fB-r | --refresh\f1
|Tell an already running avahi-autoipd to re-announce the acquired IP address on the specified network interface. (Equivalent to sending a SIGHUP)
|\fB-c | --check\f1
|Return 0 as return code if avahi-autoipd is already running for the specified network interface.
|\fB-s | --syslog\f1
|Log to syslog instead of STDERR. Implied by \fB--daemonize\f1.
|Enable verbose mode.
|Don't drop root privileges after startup. We recommend not to use this option.
|Don't \fBchroot(2)\f1 the daemon. This option is only available when compiled with chroot() support.
|\fB-S | --start=\f1
|Try to acquire the specified IP address, which must be from the IPv4LL range 169.254.0.0/16.
|\fB-w | --wait\f1
|Wait until a IP address has been successfully acquired before detaching. Only valid in combination with \fB--daemonize\f1.
|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.
|\fB-h | --help\f1
|\fB-v | --version\f1
|Show version information.
|\fI/home/lennart/tmp/avahi/etc/avahi/avahi-autoipd.action\f1: the script to run when an IP address as been acquired or is lost.
|\fISIGINT, SIGTERM\f1: avahi-autoipd will shutdown. (Same as \fB--kill\f1)
|\fISIGHUP\f1: avahi-autoipd will re-announce the acquired IP address. (Same as \fB--refresh\f1)
