   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.
