#!/bin/bash # # In the interest of keeping the KVP daemon code free of distro specific # information; the kvp daemon code invokes this external script to configure # the interface. # # The only argument to this script is the configuration file that is to # be used to configure the interface. # # Here is the format of the ip configuration file: # # HWADDR=macaddr # DEVICE=interface name # BOOTPROTO=<protocol> (where <protocol> is "dhcp" if DHCP is configured # or "none" if no boot-time protocol should be used) # # IPADDR0=ipaddr1 # IPADDR1=ipaddr2 # IPADDRx=ipaddry (where y = x + 1) # # NETMASK0=netmask1 # NETMASKx=netmasky (where y = x + 1) # # GATEWAY=ipaddr1 # GATEWAYx=ipaddry (where y = x + 1) # # DNSx=ipaddrx (where first DNS address is tagged as DNS1 etc) # # IPV6 addresses will be tagged as IPV6ADDR, IPV6 gateway will be # tagged as IPV6_DEFAULTGW and IPV6 NETMASK will be tagged as # IPV6NETMASK. # # The host can specify multiple ipv4 and ipv6 addresses to be # configured for the interface. Furthermore, the configuration # needs to be persistent.
