NAME

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

CONTENTS

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(Gx666);
   $desc->close;



DESCRIPTION

This is the class for creating a layer 3 descriptor.

ATTRIBUTES

<B>dstB> The target IPv4 or IPv6 address we will send frames to.
<B>familyB> Address family, see <B>Net::Write::LayerB> CONSTANTS section.
<B>protocolB> Transport layer protocol to use, see <B>Net::Write::LayerB> CONSTANTS section.

METHODS

<B>newB> Object constructor. You MUST pass a valid <B>dstB> attribute. Default values:

protocol: NW_IPPROTO_RAW

family: NW_AF_INET

<B>openB> Open the interface.
<B>sendB> (scalar) Send raw data to the network.
<B>closeB> 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).
