WOL not working from nodes anymore 1.4.4
-
@hanz Try to issue a call to the FOG server’s WOL route directly: https://wiki.fogproject.org/wiki/index.php?title=Troubleshoot_Web_Interface#Manually_test_WOL
See if that wakes them up or not. If that works, we have an issue. If not, go find a WOL utility and see if that wakes them up or not - if this fails, it’s not fog’s problem - if it works, we have an issue.
-
The fact that it worked, then stopped working seems to me to not be FOG related. I’m assuming you mean it even worked while on the same exact version of fog, just it stopped working one day. Did anything in the networking environment change? Switches, multicast settings, udp settings, etc…?

@wayne-workman Manually this is the page it took me to.

chain -ar http://X.X.X.X/fog/service/ipxe/boot.php##paramsI subbed the ips for X, and no wake, nor with WakeOnLan though so not sure…No change in network at all, but we are running SCCM current branch now, which was the only change now that I think about it.
::Update
WakeMeOnLan isn’t even working locally, although I was told otherwise earlier today. Might have some issues…I believe it was still 1.4.4 end of summer was still working. Upgraded OS to fedora 26 and moved server from physical to Hyper-V, but all other aspects working of course. -

I’m guessing this is the utility you found to test WOL outside of FOG. If that’s not working, this isn’t a fog problem.

@wayne-workman I’m actually curious how I could verify that the nodes are sending the packets on command ? I have 7 nodes in different subnets, and not 100% certain this was working on this version (although I’ve not seen any issues posted). I can verify at the beginning of summer it was working, but not sure what version and when beyond that scope.
Can you verify that power management and Wake via Basic Tasks–> Advanced --> Wake-Up are the exact same ?

The current FOG Server engine is complex to understand really. It is very abstracted at many points and it just doesn’t click for me.

You could always use an old hub to do a packet capture between the host and server. It’s important to use a HUB and not a Switch - because a hub will forward all packets to all ports, a cheap switch won’t.

@hanz WOL verified with wireshark being sent and found the culprit to be fastboot with Windows 10.
Registry gpo and viola ! Thanks fellas for ruling some things out.
-
@hanz If you wouldn’t mind, please expand on what you had to set in the GPO to correct this. Your solution will probably help the next FOG Admin who’s pulling his hair out trying to understand what happened…

@hanz Thank you very much for your feedback.
