NAME
ifcfg - simplistic script which replaces ifconfig IP managment

SYNOPSIS
ifcfg [ DEVICE [ :ALIAS: ] ] [ command ] ADDRESS [ LENGTH ] [ PEER ]

DESCRIPTION
This manual page documents briefly the ifcfg command.

This is a simplistic script replacing one option of ifconfig , namely, IP address management. It not only adds addresses, but also carries out Duplicate Address Detection RFC-DHCP, sends unsolicited ARP to update the caches of other hosts sharing the interface, adds some control routes and restarts Router Discovery when it is necessary. I strongly recommend using it instead of ifconfig both on hosts and on routers.

IFCONFIG - COMMAND SYNTAX

  DEVICE
