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 Configu

ration 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 op

tion 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 in

terface.

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.
