[UWPVIOLATOR]

Issue is resolved or us

Looks like our WOL Broadcast Management settings were all wiped. Adding our Broadcast IP back and it worked.

@Tom-Elliott @alexandh

I am lost. What needed to be fixed or what should I do to see what’s going on our end?

[Tom Elliott]

@alexandh If I had to guess as to the problem of some clients working vs some clients not working, it’s related to VLAN?

[alexandh]

@Tom-Elliott said in WOL RC7 Not working:

tcpdump -i ens32 -ttttvvvvnS port 9

Had to fix an issue with RC-2+ because boot.php fatal error and now fully working on 1.4.0-RC-8 : https://forums.fogproject.org/topic/9864/could-not-boot

UDP packets are now emitted!

Some clients work now.
Looks good.

[Tom Elliott]

So to further drive home all of this. I ran through RC’s 1 through 8 and tested. I have one laptop that i had not had connected to FOG at all, so I decided to make a host entry.

I also tested working branch just to ensure things were still operational in current code base.

I tested Deploy WOL, Capture WOL, and plain-jane WOL Task types. All RC’s worked from this point forward.

Just to ensure things in the automated realm were still operational I also tested Deploy/capture using FOG Scheduler to start the host as needed. Things worked properly using the current code base.

[Tom Elliott]

So based on the information I’m seeing, there is indeed no changes to code. As to why your’s isn’t working I don’t know.

My comand for tcpdump is:

tcpdump -i ens32 -ttttvvvvnS port 9

All I’m doing is a Wake Up Task.

For what it’s worth Testing with capture and deploy to the same host (for testing purposes) appears to be working as expected as well. I’ve tested with multiple nics on one host and single nic on another host and all packets required to be sent appear to be sending.

[Tom Elliott]

Just tested:

These are the “dumps” I’m seeing:

@alexandh
This means the problem should be in the _msg code or at creating $ip…

[alexandh]

@Tom-Elliott
This does not work neither does any wake task or wake tasks with deploy or upload…

I tested a script imitating the code with creating the socket and that works:

<?php
$msg=sprintf(
                '%s%s',
                str_repeat(chr(255), 6),
                str_repeat("901B0ECA8977", 16)
            );

/**
         * Assume return will be true for now.
         */
        /**
         * Create our socket resource
         */
        $sock = @socket_create(
            AF_INET,
            SOCK_DGRAM,
            SOL_UDP
        );
        /**
         * If failed, immediately return.
         */
        if ($sock == false) {
            return false;
        }
        /**
         * Set our coket options
         */
        $set_opt = @socket_set_option(
            $sock,
            SOL_SOCKET,
            SO_BROADCAST,
            true
        );
        /**
         * If invalid close socket and return immediately.
         */
        if ($set_opt < 0) {
            @socket_close($sock);
            return false;
        }
        /**
         * Send our wake up packet.
         */
        $sendto = @socket_sendto(
            $sock,
            $msg,
            strlen($msg),
            0,
            "255.255.255.255",
            9
        );
        /**
         * If failed set return to false;
         */
        if (!$sendto) {
            $ret = false;
        }
        /**
         * Close the socket.
         */
        @socket_close($sock);
        /**
         * Return value
         */

?>

tcpdump says then:
IP xxx.xxx.xxx.xxx.45962 > 255.255.255.255.9: UDP, length 198

@alexandh As I asked, can you install RC-6 and see if all works?

Mind trying:

http://fogserver/fog/index.php?sub=wakeEmUp&mac=<macofhost>

I don’t think it’s the code sending the wake on lan, rather it is missing when to send it.

Is this ALL tasks or once again ONLY the wake task?

[alexandh]

We have the same problem, that WOL is not working

Indeed the problems do not reflect a WOL problem.

We updated from fog 0.32 to 1.3.5 . After that WOL is not working. Same with 1.4.0-RC-8.
I monitored the output on the network card with tcpdump with the result that no packets are generated. With the wakeonlan command, the packet is generated and the client wakes up…

[Tom Elliott]

Typo’d sorry. Updated the command to use the proper thing. I don’t know. No changes. Maybe you might be able to install RC-6 see if it worked, if so i can mroe direclty figure out where a problem was introduced.

@Tom-Elliott

sudo chown -R fog:www-root /var/log/apache2; chmod -R 755 /var/log/apache2
chown: invalid group: ‘fog:www-root’

Also where can I look to see why WOL stopped working?

[Tom Elliott]

To fix the streaming issue,

run chown -R fog:www-data /var/log/apache2; chmod -R 755 /var/log/apache2 and you should have your logs available until the next time logrotate runs.

[Tom Elliott]

These messages have no bearing in regards to WOL. Nothing has changed for WOL since March 8, which 1.4.0-RC-1 was released and proven to have been working (was released 24-MAR-2017).
