NAME

       Net::Write::Layer - base class and constants

SYNOPSIS

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

DESCRIPTION

       This is the base class for Net::Write::Layer2, Net::Write::Layer3 and Net::Write::Layer4 modules.

       It just provides those layers with inheritable attributes, methods and constants.

ATTRIBUTES

       dev Network interface to use.

       dst Target IPv4 or IPv6 address.

       protocol
	   Transport layer protocol to use (TCP, UDP, ...).

       family
	   Adresse family to use (NW_AF_INET, NW_AF_INET6).

METHODS

       new Object constructor.

       open
	   Open the descriptor, when you are ready to send.

       send (scalar)
	   Send the raw data passed as a parameter. Returns undef on failure, true otherwise.

       close
	   Close the descriptor.

CONSTANTS

       NW_AF_INET
       NW_AF_INET6
       NW_AF_UNSPEC
	   Address family constants, for use with family attribute.

       NW_IPPROTO_IP
       NW_IPPROTO_IPv6
       NW_IPPROTO_ICMPv4
       NW_IPPROTO_TCP
       NW_IPPROTO_UDP
       NW_IPPROTO_ICMPv6
	   Transport layer protocol constants, for use with protocol attribute.

       NW_IP_HDRINCL
       NW_IPPROTO_RAW
	   Mostly used internally.

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).
