WOL ? Computer boot/start alone

[george1421]

@steuve68 said in WOL ? Computer boot/start alone:

IP IPFOGSERVER.35593 > IPOFCOMPUTER.445

This I can tell you is the fog server “pinging” the computer to see if its up. I can tell you that fog “pings” using this method instead of a traditional icmp ping. Why ?? I don’t know.

This does sound like what x23 says a fog “ping” will wake up the host. After fog starts I don’t know what those packets are.

I wonder of FOG will wake up the computer from a power up off state instead of a windows shutdown state?

[Steuve68]

So … I have update my Network Device Drivers
I have enabled “Wake on Pattern Match” for test.

For the moment the computer doesn’t start alone automatically.

I do not understand why suddenly the network drivers would be problematic.

I suspect the update Microsoft KB4103718 (https://borncity.com/win/2018/05/27/windows-7-update-kb4103718-network-issues-fixed/) which is a priori known to pose problems with network card.

That’s very strange …

@steuve68 have u tried to turn of hibernation by “powercfg -h off” in an evaluated cmd prompt?

[Steuve68]

@x23piracy No, i have just update NIC Device for test on this machine.
But hibernation mode is off
When i run: powercfg -a
“La mise en veille prolongée n’a pas été activée”

@steuve68 here is a link for the 2 years old conversation i had with tom about it:
https://pastebin.com/L1ixBrZd @tom-elliott don’t bash me for sharing this

[Tom Elliott]

@x23piracy why would I bash you. The only wake up code is in fog scheduler still.

Ping hosts just tests the status of a host. The reason we use 445 @george1421 is so we can get a status. Ping itself just tests if the host is pingable, but that doesn’t necessarily mean anything. Using 445 we can get a real status like refused, no address, etc…

So fog isn’t causing the problem being seen, but it is playing a part. That part is not by any means “fogs” fault, rather a configuration issue on the workstations.

[Steuve68]

@x23piracy I have test “powercfg -h off” with elevated privilege on 2 problematic computers
No change: computers start always alone.

For the moment the only solution what I found it’s up to date NIC Drivers …

@Tom-Elliott “Ping hosts just tests the status of a host.” => Can I disable this option into FOG ?

Thanks all

[Tom Elliott]

@steuve68 yes under fog settings Linux service.

[Steuve68]

@tom-elliott OK thanks
It’s that: PINGHOSTGLOBALENABLED ?

No secondary effect if i uncheck this option ?

[Steuve68]

@Tom-Elliott After uncheck PINGHOSTGLOBALENABLED, it’s OK.
Computer don’t start/boot alone.
WOL tasks always good !

No secondary effect ?

Thanks all

@steuve68 You won’t be able to see if hosts are online with it disabled but that should be it afaik.

[x23piracy]

@steuve68 and in the end it was the online check from fog activating that computers, like i told you I still have the ping check enabled i solved my problems around that with hibernating off und pattern match in nic drivers disabled.
