NAME         top

       ifcfg - simplistic script which replaces ifconfig IP management

SYNOPSIS         top

       ifcfg [ DEVICE ] [ command ] ADDRESS [ PEER ]

DESCRIPTION         top

       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.


       DEVICE - it may have alias, suffix, separated by colon.

              - add, delete or stop.

              - optionally followed by prefix length.

       peer   - optional peer address for pointpoint interfaces.

NOTES         top

       This script is not suitable for use with IPv6.
