wake on lan (php) cannot get it to work

5.7k Views Asked by At

Trying to make php wake on lan work (via internet).

Through wolcmd program I can successfully turn on server from internet with command:

/Users/usr/Downloads/wolcmd [mac] [public IP] 255.255.255.255 1009

So there is no router/server issue.

I've found several php scripts on internet, but non of them work! :S

tried:

<?php

flush();

function WakeOnLan($addr, $mac,$socket_number) {    
  $addr_byte = explode(':', $mac);
  $hw_addr = '';

  for ($a=0; $a <6; $a++) $hw_addr .= chr(hexdec($addr_byte[$a]));

  $msg = chr(255).chr(255).chr(255).chr(255).chr(255).chr(255);

  for ($a = 1; $a <= 16; $a++) $msg .= $hw_addr;

  // send it to the broadcast address using UDP
  // SQL_BROADCAST option isn't help!!
  $s = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);

  if ($s == false) {
    echo "Error creating socket!\n";
    echo "Error code is '".socket_last_error($s)."' - " . socket_strerror(socket_last_error($s));
    return FALSE;
  } else {
    // setting a broadcast option to socket:
    $opt_ret = socket_set_option($s, 1, 6, TRUE);

    if ($opt_ret < 0) {
      echo "setsockopt() failed, error: " . strerror($opt_ret) . "\n";
      return FALSE;
    }

    if (socket_sendto($s, $msg, strlen($msg), 0, $addr, $socket_number)) {
      echo "Magic Packet sent successfully!";
      socket_close($s);
      return TRUE;
    } else {
      echo "Magic packet failed!";
      return FALSE;
    }
  }
}

// Port number where the computer is listening. Usually, any number between 1-50000 will do. Normally people choose 7 or 9.
$socket_number = "1009";
// MAC Address of the listening computer's network device
$mac_addy = "XX:XX:XX:XX:XX:XX";
// IP address of the listening computer. Input the domain name if you are using a hostname (like when under Dynamic DNS/IP)
$ip_addy = gethostbyname("name.dyndns.org");

WakeOnLan($ip_addy, $mac_addy,$socket_number)

?>

This script gives me success, but server doesn't wake up. Plus there is no way to specify: 255.255.255.255

I also tried to use packet sniffer on my laptop (not server) and I didn't see any UDP packages arrive.

Another script I tried is this:

// TCP Port on device to check, example "3389" = RDP, "80" = WebServer.
$deviceport = "1009";
// MAC address of NIC1 on device, example "00:00:00:00:00:00" or "00-00-00-00-00-00".

// MAC address of NIC2 on device, example "00:00:00:00:00:00" or "00-00-00-00-00-00". - Optional set to "" if NIC2 not required.
$devicemac2 = "";

here problematic is $deviceport = "1009"; if I specify 80 it tells me host is down... but that I know already :) that's why I'm sending magic packet right?...

Please can someone with experience in this help? I'm out of ideas to try.

EDIT 2015

Well, I've cleaned up my process, this works perfectly: https://github.com/wearede/wake-on-wan

old

It works now! I can wake up my server by simply visiting a subdomain wol.domain.com :) cool.

Lesson learned: above script wasn't functioning because I had mis-configured router. As you can see from the script, correct port is 1009. On router I had it set-up incoming port 1009 redirecting wihin lan to port 9. For some reason (maybe because it's UDP?) 1009->9 isn't working. I did 1009->1009 and server did wake up!

Final code I used:

You should consider using this simple-sample script :

Mac :

<?php

system("/Users/usr/Downloads/wolcmd [mac] [public IP] 255.255.255.255 1009");

?>

Or Linux :

<?php

system("wakeonlan arg1 arg2 ...");

?>

To install this command on Debian and derivate : 

sudo apt-get install wakeonlan
