WOL and Task doesn't work

[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…:-(

[Junkhacker]

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!

[Raff]

Raffa,

The only thing I can suggest now is to try it with a server with a single card configured to use eth0.
