WOL and Task doesn't work

Raff

Is the fog server on same VLAN as the clients?

theleftfoot

yes, default vlan 1 --> all access ports.

Raff

Put Wireshark on a client and start monitoring, send the packet from fog server to check if it receives it.

theleftfoot

i dind’t receive any WOL Magic packets on wireshark.

i send a wake up call to a notebook in the same network and this worked great.
the protocol WOL was visible on wireshark…

can you show me a working WOL.php? i leave the wol.php as it is out of the box…should i configure something?

thanks raffa

Tom Elliott

The very one in your FOG server IS a working wol.php file.

I just tested, across VLAN’s even and all worked perfectly. I started a LAB of 32 systems with no issues.

theleftfoot

thanks tom, but the server doesn’t send any WOL packets! i don’t know where to start with trouble shooting…i think my network, is correct…

maybe something with DNS, cause i have still the problem with the unresolved host names…

Tom Elliott

If you need to see things, remember WOL packets are magic like. There’s not really a DNS setup for them as it WOL assumes the systems is either up or down based on the MAC Address. FOG uses Port UDP 9 if it’s of any help to you.

There are three files dealing with WOL in general with fog.

First: fog/wol/wol.php
[php]<?php
// Require FOG Base
require(‘…/commons/base.inc.php’);
try
{
$MACAddress = new MACAddress($REQUEST[‘wakeonlan’]);
if ($MACAddress->isValid())
{
$wol = new WakeOnLan($MACAddress->getMACWithColon());
$wol->send();
}
else
throw new Exception((‘Invalid MAC Address!’));
}
catch (Exception $e){print $e->getMessage();}[/php]
Second: fog/lib/fog/FOGCore.class.php Lines: 264-268
[php] public function wakeOnLAN($mac)
{
// HTTP request to WOL script
$this->fetchURL(sprintf(‘http://%s%s?wakeonlan=%s’, $this->getSetting(‘FOG_WOL_HOST’), $this->getSetting(‘FOG_WOL_PATH’), ($mac instanceof MACAddress ? $mac->getMACWithColon() : $mac)));
}
[/php]
Third (the important one) is the WakeOnLan.class.php in lib/fog.
[php]<?php
/** \class WakeOnLan
Builds the magic packet needed for waking systems from LAN.
*/
class WakeOnLan
{
private $strMac;

/** __construct($mac)
    Stores the MAC of which to system to wake.
*/
public function __construct( $mac )
{   
    $this->strMac = $mac;
}   

/** send()
    Creates the packet and sends it to wake up the machine.
*/
public function send()
{   
    if ( $this->strMac != null )
    {   
        $arByte = explode(':', $this->strMac);

        $strAddr = null;

        for ($i=0; $i<count( $arByte); $i++) 
            $strAddr .= chr(hexdec($arByte[$i]));

        $strRaw = null;
        for ($i=0; $i<6; $i++) 
            $strRaw .= chr(255);

        for ($i=0; $i<16; $i++) 
            $strRaw .= $strAddr;

        $soc = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
        if ( $soc !== FALSE )
        {   
            if(socket_set_option($soc, SOL_SOCKET, SO_BROADCAST, TRUE)) 
            {   
                if( socket_sendto($soc, $strRaw, strlen($strRaw), 0, "255.255.255.255", 9) ) 
                {   
                    socket_close($soc);
                    return true;
                }   
                else 
                    return false;    
            }   
            else
                new Exception( "Failed to set option!");    
        }   
        else
        {   
            $errCd = socket_last_error();
            $errMsg = socket_strerror($errCd);
            throw new Exception( "Socket Error: $errCd :: $errMsg" );
        }
    }
    return false;
}

}[/php]

Hopefully this makes sense, but I assure you, it does work.

yepp, have the same files…i don’t know whats wrong…apart from mine WOL problem the “active task” didn’t work aswell…:-(

does a wol packet sent manually from the server work?

theleftfoot

how can i test this? sorry for my lack of knowledge…:-/

Tom Elliott

Easiest method.

Create a file in wol called testwol.php

Place these commands:

[php]<?php
require_once(‘…/commons/base.inc.php’);
$mac = ‘XX:XX:XX:XX:XX:XX’;
$WOLtest = new WakeOnLan($mac);
if ($WOLtest->send())
print 'WOL Packet <b>SENT</b> to '.$mac;
else
print 'WOL Packet <b>NOT SENT</b> to '.$mac;
?>[/php]

Replace the XX’s with that of one of the MAC’s you want to wake up.

In your browser, go to [url]http://<FOGSERVERIP>/fog/wol/testwol.php[/url]
You should see the output:
[code]WOL Packet SENT to XX:XX:XX:XX:XX:XX[/code]

With any luck, this actually wakes the system up too!

Junkhacker

or to test independently of anything fog related, use etherwake. [url]http://manpages.ubuntu.com/manpages/quantal/man8/etherwake.8.html[/url]
i think you will find that if fog fails to do it, so will this. because the problem is not in fog.

theleftfoot

thanks guys, will checked right now!

raffa

theleftfoot

okay, try the testwol.php script…but the notebook still sleeps!

i made a arp-scan on eth1 and the mac adress is not visible, because the node sleeps and is not on.

the fog wol stettings are attached and the network schema…
[ATTACH]804[/ATTACH][ATTACH]805[/ATTACH]

it might be due to the 2 network interface card? miss configuration?

damm…raffa

Raff

Change Settings FOG_WOL_INTERFACE to eth1.

theleftfoot

raff, like the pic above show --> it is on eth1

raffa

Raff

Your pic just tells us that your using connection eth1, not that you have configured fog to use eth1 for WOL in the fog settings.

check /var/www/fog/commons/config.php or use the console

define(‘WOL_HOST’, “1.1.1.1”);
define(‘WOL_PATH’, ‘/fog/wol/wol.php’);
define(‘WOL_INTERFACE’, “eth0”);

Raff

In your pic your fog host is 192.168.1.2 but in your configuration its 192.168.1.1, is that an error in the pic or have you changed the static IP on the server.

theleftfoot

the pictures is wrong…192.168.1.1 is corrcet!
