NAME
avahi-autoipd.action - avahi-autoipd action scriptSYNOPSIS
/etc/avahi/avahi-autoipd.actionDESCRIPTION
avahi-autoipd.action is the action script that is called whenever an IP address has been acquired by avahi-autoipd or when it detected an IP address conflict. The script should add or remove the specified address from the specified network interface.PARAMETERS
- argv[1] An event string: one of BIND, CONFLICT, UNBIND or STOP. If BIND is passed an IP address has been successfully acquired and the script shall add it to the network interface. If CONFLICT is passed avahi-autopid detected a IP address on the local network, the action script should remove the configured IP address. If UNBIND is passed the IP address should be removed from the interface, too, because a routable address has been configured to the interface by some other program. If STOP is passed the avahi-autoipd is being shutdown and the action script should remove the IP address. In short: on BIND the address should be added to the interface, on CONFLICT, UNBIND or STOP it should be removed.
- argv[2] The network interface name.
- argv[3] An IP address from the IPv4LL range.

NAME
avahi-autoipd - IPv4LL network address configuration daemonSYNOPSIS
avahi-autoipd [options] interfaceavahi-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 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 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 information.
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 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.
- --debug
- Enable verbose mode.
- --no-drop-root
- Don't drop root privileges 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 successfully 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.
