zeroconfd - daemon for autoconfiguration of IPv4 link-local addresses
The daemon tries to configurate one or more network interfaces with a
link-local address, according to the Zeroconf project.
On startup,it reads the interfaces to run on in the file
/etc/zeroconfd.conf. The names of the interfaces are simply listed one
for line in this file. It chooses a random address in the class
169.254/24 for each interface and then brodcasts some ARP requests to
verify that no other host with the same address is attached to the net.
Then it announces his address with some gratuitous ARP response. It keeps
listening on the interface, in order to indentify conflicts with other
hosts, and to defend his address.
It saves the address successfully configurated in a file and when started
tries to configure each interface with the previous address configured.
The receiving of a SIGHUP causes the daemon to reread his configuration
file, and eventually to start configuring a new interface.
In normal operation, it forks and run as a daemon. Errors are reported
The daemon is run by dhclient-script when it does not succeed in finding
a dhcp server and in obtaining a lease.
-d Run in debug mode. Don't fork, write error and debug
messages to stderr.
-h Print help information.
-v Show version.
