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 <a href="http://developer.apple.com/qa/qa2004/qa1357.html" title="http://developer.apple.com/qa/qa2004/qa1357.html">http://developer.apple.com/qa/qa2004/qa1357.html</a> 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 it's 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) AUTHORS The Avahi Developers <avahi (at) lists (dot) freedesktop (dot) org>; Avahi is available from <a href="http://avahi.org/" title="http://avahi.org/">http://avahi.org/</a> SEE ALSO autoipd.action(8), dhclient(8) <a href="http://avahi.org/wiki/AvahiAutoipd" title="http://avahi.org/wiki/AvahiAutoipd">http://avahi.org/wiki/AvahiAutoipd</a> documents how avahi-autoipd is best packaged and integrated into distributions.
