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

Returns undef on error.

open

Open the interface. Returns undef on error.

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).
