net::write::layer3
Net::Write::Layer3(3pm) User Contributed Perl Documentation Net::Write::Layer3(3pm)
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).
