NAME

       Net::Write::Layer3 - object for a network layer (layer 3) descriptor

SYNOPSIS

	  use Net::Write::Layer qw(:constants);
	  use Net::Write::Layer3;

	  my $desc = Net::Write::Layer3->new(
	     dst      => '192.168.0.1',
	     protocol => NW_IPPROTO_RAW,
	     family   => NW_AF_INET,
	  );

	  $desc->open;
	  $desc->send('G'x666);
	  $desc->close;

DESCRIPTION

       This is the class for creating a layer 3 descriptor.

ATTRIBUTES

       dst The target IPv4 or IPv6 address we will send frames to.

       family
	   Address family, see Net::Write::Layer CONSTANTS section.

       protocol
	   Transport layer protocol to use, see Net::Write::Layer CONSTANTS section.

METHODS

       new Object constructor. You MUST pass a valid dst attribute. Default values:

	   protocol: NW_IPPROTO_RAW

	   family:   NW_AF_INET

       open
	   Open the interface.

       send (scalar)
	   Send raw data to the network.

       close
	   Close the descriptor.

CAVEATS

       Sending IPv6 frames does not work under BSD systems. They can't do IP_HDRINCL for IPv6. For now, only Linux supports this (at least, with a
       2.6.x kernel).

       Does not work at all under Win32 systems. They can't send frames at layer 3 (or I don't know how to do that).
