4# This example script activates an interface based on the specified
5# configuration.
6#
7# In the interest of keeping the KVP daemon code free of distro specific
8# information; the kvp daemon code invokes this external script to configure
9# the interface.
10#
11# The only argument to this script is the configuration file that is to
12# be used to configure the interface.
13#
14# Each Distro is expected to implement this script in a distro specific
15# fashion. For instance, on Distros that ship with Network Manager enabled,
16# this script can be based on the Network Manager APIs for configuring the
17# interface.
18#
19# This example script is based on a RHEL environment.
20#
21# Here is the ifcfg format of the ip configuration file:
22#
23# HWADDR=macaddr
24# DEVICE=interface name
25# BOOTPROTO=<protocol> (where <protocol> is "dhcp" if DHCP is configured
26# 			or "none" if no boot-time protocol should be used)
27#
28# IPADDR0=ipaddr1
29# IPADDR1=ipaddr2
30# IPADDRx=ipaddry (where y = x + 1)
31#
32# NETMASK0=netmask1
33# NETMASKx=netmasky (where y = x + 1)
34#
35# GATEWAY=ipaddr1
36# GATEWAYx=ipaddry (where y = x + 1)
37#
38# DNSx=ipaddrx (where first DNS address is tagged as DNS1 etc)
39#
40# IPV6 addresses will be tagged as IPV6ADDR, IPV6 gateway will be
41# tagged as IPV6_DEFAULTGW and IPV6 NETMASK will be tagged as
42# IPV6NETMASK.
43#
44# Here is the keyfile format of the ip configuration file:
45#
46# [ethernet]
47# mac-address=macaddr
48# [connection]
49# interface-name=interface name
50#
51# [ipv4]
52# method=<protocol> (where <protocol> is "auto" if DHCP is configured
53#                       or "manual" if no boot-time protocol should be used)
54#
55# address1=ipaddr1/plen
56# address2=ipaddr2/plen
57#
58# gateway=gateway1;gateway2
59#
60# dns=dns1;
61#
62# [ipv6]
63# address1=ipaddr1/plen
64# address2=ipaddr2/plen
65#
66# gateway=gateway1;gateway2
67#
68# dns=dns1;dns2
69#
70# The host can specify multiple ipv4 and ipv6 addresses to be
71# configured for the interface. Furthermore, the configuration
72# needs to be persistent. A subsequent GET call on the interface
73# is expected to return the configuration that is set via the SET
74# call.
