zcip(8)

zcip8

Zero configure network interface

Usage

zcip [-hsv] [-i interface]

Overview

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.

[-d] , [--default]

Add a default route to this interface in addition to the standard network route.

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.

Releases

Unchanged in 2 releases since Debian 3.1 (Sarge).

  1. 3.1–4.0

Bugs

zcip currently assumes that the target interface is down and reconfigures 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 (CONFIG_FILTER). You get infinite looping through a lot of IPs in a hurry.
