NAME

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: \Device\NPF_{0749A9BC-C665-4C55-A4A7-34AC2FBAB70F}

METHODS

new

Object constructor. You MUST pass a valid dev attribute. There is no default value. 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

Writing junk to loopback interface on BSD systems will not work.
