NAME

POE::Component::WakeOnLAN - A POE Component to send packets to power on computers.

SYNOPSIS

use strict;
use warnings;
use Data::Dumper;
use POE;
use POE::Component::WakeOnLAN;

my $mac_address = '00:0a:e4:4b:b0:94';

POE::Session->create(
   package_states => [
	'main' => [qw(_start _response)],
   ],
);


$poe_kernel->run();
exit 0;

sub _start {
  POE::Component::WakeOnLAN->wake_up( 
	macaddr => $mac_address,
	event   => '_response',
  );
  return;
}

sub _response {
  print Dumper( $_[ARG0] );
  return;
}

DESCRIPTION

POE::Component::WakeOnLAN is a POE component that sends wake-on-lan (AKA magic) packets to turn on machines that are wake-on-lan capable.

It is based on the Net::Wake module by Clinton Wong.

CONSTRUCTOR

wake_up

Sends a wake-on-lan packet via UDP. Takes a number of parameters:

'macaddr', the MAC Address of the host to wake up, mandatory;
'event', the event handler in your session where the result should be sent, mandatory;
'address', the IP address of the host to wake up, defaults to 255.255.255.255;
'port', the UDP port to communicate with, defaults to 9;
'session', optional if the poco is spawned from within another session;
'options', a hashref of POE Session options to pass to the component;

Generally speaking, you should use a broadcast address for address ( the component defaults to using 255.255.255.255 if one is not supplied ), Using the host's last known IP address is usually not sufficient since the IP address may no longer be in the ARP cache.

If you wish to send a magic packet to a remote subnet, you can use a variation of '192.168.0.255', given that you know the subnet mask to generate the proper broadcast address.

The session parameter is only required if you wish the output event to go to a different session than the calling session, or if you have spawned the poco outside of a session.

You may pass through any arbitary parameters you like, though they must be prefixed with an underscore to prevent future parameter clashes. These will be returned to you in the resultant event response.

The poco does it's work and will return the output event with the result.

OUTPUT EVENT

This is generated by the poco. ARG0 will be a hash reference with the following keys:

'macaddr', the MAC address that was specified, the poco strips ':';
'address', the IP address that was used;
'port', the UDP port that was used;

Plus an arbitary key/values that were passed.
