Net::Write::Layer2 - object for a link layer (layer 2) descriptor
SYNOPSIS
use Net::Write::Layer2;
my $desc = Net::Write::Layer2->new(
dev => 'eth0',
);
$desc->open;
$desc->send('G'x666);
$desc->close;
DESCRIPTION
This is the class for creating a layer 2 descriptor.
ATTRIBUTES
dev The string specifying network interface to use.
Under Unix-like systems, this is in this format: w+d+ (example: eth0).
Under Windows systems, this is more complex; example: DeviceNPF_{0749A9BC-C665-4C55-A4A7-34AC2FBAB70F}
METHODS
new Object constructor. You MUST pass a valid dev attribute. There is no default value.
open
Open the interface.
send (scalar)
Send raw data to the network.
close
Close the descriptor.
CAVEATS
Writing junk to loopback interface on BSD systems will not work.

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
