method loopback
  description
    This method may be used to define the IPv4 loopback interface.

    route add -net 127.0.0.0       if ( mylinuxver() < mylinux(2,1,100) )

method static
  description
    This method may be used to define ethernet interfaces with statically
    allocated IPv4 addresses.
      
  options
    address address             -- Address (dotted quad) *required*
    netmask netmask             -- Netmask (dotted quad) *required*
    broadcast broadcast_address -- Broadcast address (dotted quad)
    network network_address     -- Network address (dotted quad) *required \
                                     for 2.0.x kernels*
    gateway address             -- Default gateway (dotted quad)
    pointopoint address		-- Address of other end point (dotted quad). \
				   Note the spelling of "point-to".
    media type                  -- Medium type, driver dependent
    hwaddress class address     -- Hardware Address. /class/ is one of \
                                     *ether*, *ax25*, *ARCnet* or *netrom*. \
                                     /address/ is dependent on the above \
                                     choice.

method dhcp
  description
    This method may be used to obtain an address via DHCP with any of
    the tools: dhclient, pump (Linux 2.2.x and newer),
    udhcpc (Linux 2.2.x and newer), or dhcpcd.
    If you have a complicated DHCP setup you should
    note that some of these clients use their own configuration files,
    rather than obtaining their configuration via *ifup*.

  options
    hostname hostname   -- Hostname to be requested (pump, dhcpcd, udhcpc)
    leasehours leastime -- Preferred lease time in hours (pump)
    leasetime leasetime -- Preferred lease time in seconds (dhcpcd)
    vendor vendor       -- Vendor class identifier (dhcpcd)
    client client_id    -- Client identifier (dhcpcd, udhcpc)

  up
    dhclient -pf /var/run/dhclient.%iface%.pid %iface%  \
        if (execable("/sbin/dhclient"))
    pump -i %iface% [[-h %hostname%]] [[-l %leasehours%]] \
        elsif (execable("/sbin/pump") && mylinuxver() >= mylinux(2,1,100))
    udhcpc -n -p /var/run/udhcpc.%iface%.pid -i %iface% [[-H %hostname%]] \
           [[-c %clientid%]] \
        elsif (execable("/sbin/udhcpc") && mylinuxver() >= mylinux(2,2,0))
    dhcpcd [[-h %hostname%]] [[-i %vendor%]] [[-I %clientid%]] \
           [[-l %leasetime%]] %iface% \

        elsif (execable("/sbin/udhcpc"))
    dhcpcd -k %iface% \
        elsif (execable("/sbin/dhcpcd"))

    ifconfig %iface% down
method bootp
  description
    This method may be used to obtain an address via bootp.

  options
    bootfile file  -- Tell the server to use /file/ as the bootfile.
    server address -- Use the IP address /address/ to communicate with \
                      the server.
    hwaddr addr    -- Use /addr/ as the hardware address instead of \
                      whatever it really is.

  up
    bootpc [[--bootfile %bootfile%]] --dev %iface% [[--server %server%]] \
           [[--hwaddr %hwaddr%]] --returniffail --serverbcast

  down
    ifconfig down %iface%
method ppp
  description
    This method uses pon/poff to configure a PPP interface. See those
    commands for details.
  options
    provider name  -- Use /name/ as the provider (from /etc/ppp/peers).
  up
    pon [[%provider%]]
  down
    poff [[%provider%]]
method wvdial
  description
    This method uses wvdial to configure a PPP interface. See that command
    for ore details.
  options
    provider name  -- Use /name/ as the provider (from /etc/ppp/peers).
  up
    /sbin/start-stop-daemon --start -x /usr/bin/wvdial \
                      -p /var/run/wvdial.%iface% -b -m -- [[ %provider% ]]
