   3 # This example script activates an interface based on the specified
   4 # configuration.
   5 #
   6 # In the interest of keeping the KVP daemon code free of distro specific
   7 # information; the kvp daemon code invokes this external script to configure
   8 # the interface.
   9 #
  10 # The only argument to this script is the configuration file that is to
  11 # be used to configure the interface.
  12 #
  13 # Each Distro is expected to implement this script in a distro specific
  14 # fashion. For instance on Distros that ship with Network Manager enabled,
  15 # this script can be based on the Network Manager APIs for configuring the
  16 # interface.
  17 #
  18 # This example script is based on a RHEL environment.
  19 #
  20 # Here is the format of the ip configuration file:
  21 #
  22 # HWADDR=macaddr
  23 # DEVICE=interface name
  24 # BOOTPROTO=<protocol> (where <protocol> is "dhcp" if DHCP is configured
  25 #                       or "none" if no boot-time protocol should be used)
  26 #
  27 # IPADDR0=ipaddr1
  28 # IPADDR1=ipaddr2
  29 # IPADDRx=ipaddry (where y = x + 1)
  30 #
  31 # NETMASK0=netmask1
  32 # NETMASKx=netmasky (where y = x + 1)
  33 #
  34 # GATEWAY=ipaddr1
  35 # GATEWAYx=ipaddry (where y = x + 1)
  36 #
  37 # DNSx=ipaddrx (where first DNS address is tagged as DNS1 etc)
  38 #
  39 # IPV6 addresses will be tagged as IPV6ADDR, IPV6 gateway will be
  40 # tagged as IPV6_DEFAULTGW and IPV6 NETMASK will be tagged as
  41 # IPV6NETMASK.
  42 #
  43 # The host can specify multiple ipv4 and ipv6 addresses to be
  44 # configured for the interface. Furthermore, the configuration
  45 # needs to be persistent. A subsequent GET call on the interface
  46 # is expected to return the configuration that is set via the SET
  47 # call.
