NAME
       zcip - zero configure network interface

SYNOPSIS
       zcip [-hsv] [-i interface]

DESCRIPTION
       zcip  does  the	ad-hoc	link-local  IPv4  auto-configuration trick, as
       described in the IETF Internet Draft  'Dynamic  Configuration  of  IPv4
       Link-Local Addresses'.

OPTIONS
       [--help] , [-h]
	      Provide brief help and usage information, and exit.

       [--syslog] , [-s]
	      Send all information to syslog, instead of standard output

       [--version] , [-v]
	      Provide version information, and exit

       [-i interface_name] , [--interface=interface_name]
	      Specifies	 the  interface	 to  configure.	 If this option is not
	      used, zcip defaults to the eth0 device.

       [-r] , [--randseed]
	      Seeds the random number generator that is	 used  to  create  the
	      interface's new IP address with a true random number rather than
	      the MAC address of the device.

FILES
       None yet, but maybe a configuration file will  be  added.  We  probably
       also need one or more files to store the IP for each interface.

BUGS
       zcip  currently assumes that the target interface is down and reconfig‐
       ures it. The IETF draft seems to suggest using multi-homing,  which  we
       don't do yet.

       There  should  be  a  configuration option to work the same way Windows
       2000 does, so we don't get beaten up so much.

       Doesn't work if packet filtering is not enabled	in  the	 kernel	 (CON‐
       FIG_FILTER). You get infinite looping through a lot of IPs in a hurry.
