I have a strange wol problem, tom please help me
x23piracy

Hi Tom, is there any place i can check to see if fog is waking up my computers again and again? i really have no idea what is causing this but after removing the host from fog they still turn on. I am busted :(
x23piracy

Hi Tom the Wake up Problem is 100% FOG caused, if i turn the fog server off machine does not wake up, when i boot fog and shutdown the computer that always turns on it happens again. The computer is no more fog registered but fog is causing the power on thats for sure.

Could you please help me in a way?

https://forums.fogproject.org/post/75832 i am crying

can i check something in fog db where maybe a wol job is pending again and again?
x23piracy

I could also remove the fog service from the problematic computer, when fog server is running it will wake that computer also if host is not registered to fog, i really need you to find out why fog is sending wol to that computers

can we please check my database to see whats causing this bad issue?

x23piracy

FYI again, sorry for bugging such hard but thats a big problem to me: https://i.imgur.com/gZFw8r7.png

Joe asked me if we two can maybe look for my issue, please give me a message if you have time tom, this is really a big problem to me 16 workstations turn on again and again and our employess hunting for my head i need help please.
Tom Elliott

I’m so confused man.

only systems that are NOT registered are running WOL?

while registered systems are fine?
x23piracy

hi tom ok lets start from scratch

i have 16 new computer, i had all of them registered to fog and deploayed my win 10 image with fog client integrated
Tom Elliott

yep.
x23piracy

while setup them up i could mention that they turn on by magic always when i shutted them dowm
Tom Elliott

okay
x23piracy

then i removed all that clients from fog and also removed the fog service from one of the machines

but they still turn on by magic
Tom Elliott

okay
x23piracy

when they boot the do a network boot not just a simple switch on
Tom Elliott

that doesn’t mean much
x23piracy

i can see this because they boot into fog menu and them the 5 second timeout let them boot os
Tom Elliott

if the systems are setup to pxe boot first

that would happen anyway

but
x23piracy

when i shutdown the fog server these clients dont wake up
Tom Elliott

i need a log

of the /opt/fog/fogscheduler.log
x23piracy

is there somethin for direct pastebin upload or something ?

could i reach the log via webif else i need winscp
Tom Elliott

you can get it from the log viewer utility built into the gui
x23piracy

i grabbed it from winscp

wayne recommended to temporarily shutdown fogscheduler

why do i have entry in tasks table? shouldn’t it be empty if i dont have any scheduled or running tasks?
Tom Elliott

tasks are handled by states

1,2,3 are “queued, inline, in progress”

4,5 are complete and cancelled
x23piracy

they all have 4 or 5
Tom Elliott

yep

that’s fine
x23piracy

i’ve stop fogscheduler
Tom Elliott

have hosts stopped WOL?
x23piracy

i will now shutdown the workstation to see if it turns on again

i just stopped it some seconds ago wait…

is it a problem that i’Ve cleared tasks table?

it’s empty now, didn’t knew that is not important if there are entrys

the workstation has switched on again while fogscheduler was stopped
Tom Elliott

okay

so what’s output of

crontab -l
x23piracy
m h dom mon dow command

@reboot sudo bash -c ‘/home/fog/restart_services.sh’ &
root@fog:/opt/fog/log#

ups sorry for the big letters :D

the only cronline is: @reboot sudo bash -c ‘/home/fog/restart_services.sh’ &
Tom Elliott

well it’s not something FOG has done that’s waking these systems up.

it can’t be

fogscheduler is the ONLY service that performs wake on lan operations

you can stop all fog services as a test.
x23piracy

it is i would be money, when i now shutdown fog server and after that the workstation it does not turn on anymore
Tom Elliott

systemctl stop FOGScheduler
x23piracy

tom i swear to you this is something fog is doing
Tom Elliott

systemctl stop FOGPingHosts

no

it’s not

i’m not saying your fog server isn’t doing anything
x23piracy

what else could it be then?
Tom Elliott

but it’s not anything FOG is doing
x23piracy

cosmic radiation ? :D
Tom Elliott

FOGScheduler is the only thing that cycles to turn systems on.

and even then, it can only do so with systems that are registered.

do you have other nodes?
x23piracy

now i have stopped both services fogscheduler and pinghosts
Tom Elliott

pinghosts has nothing to do with it

do you have multiple nodes
x23piracy

yes i have one storage node
Tom Elliott

And the main server?

so you have 2 “nodes”?
x23piracy

what about the main server?

yes 2 nodes
Tom Elliott

okay

and the other node

can you access it via GUI?

so

browser

http://<othernodesIP>/fog/
x23piracy

first normal fog with webif and less storage (vm) second physical machine with 4tb as storage node

This is a storage node, please do not access the web ui here!
Tom Elliott

okay

now on that node

what about it’s FOGService?
x23piracy

i haven’t touched the storage node while main fog server is offlien

i was not thinking about the maybe the storage node is doing the problem
Tom Elliott

can you please do it?

i need to find why it’s doing this
x23piracy

ok what should i do with the storage node?

also disable fogscheduler?
Tom Elliott

just get the log first
x23piracy

ok wait a second

the only entry in fogscheduler.log on the storage node is: [08-05-16 5:53:05 pm] * No tasks found!
Tom Elliott

and output of

systemctl -l status FOGScheduler
x23piracy

ubuntu!

service?
Tom Elliott

Doesn’t mean anything

Ubuntu 15 and up uses systemctl
x23piracy

i get comand not found
Tom Elliott

so

go ahead and stop the FOGScheduler
x23piracy

ok it’s stopped
Tom Elliott

now you stopped PingHosts on the server too?
x23piracy

no just scheduler
Tom Elliott

go ahead and restart fogscheduler

and stop pinghosts
x23piracy

ok started scheduler again and pinghosts wasn’t running because: * Stopping FOG Computer Imaging Solution: FOGPingHosts start-stop-daemon: warning: failed to kill 1570: No such process

why do you think the storage node is maybe causing this, while fog main server is off and only storage node is running workstations remain off

the problem only exists when main fog is active
Tom Elliott

just trying to see all angles
x23piracy

ok understand

you can also have system access again if you like

maybe we can see live whats triggering the wol
x23piracy

i have turned off the workstation again and since 2-3 minutes it remains off
Tom Elliott

so turn back on ping hosts.
x23piracy

on both machines?
Tom Elliott

and what’s in the /opt/fog/log/pinghosts.log file

only the main server
x23piracy

pinghosts start for both?
Tom Elliott

just the main server
x23piracy

lol

immediatelly the workstation turned on

i could here the relay from the kvm switch

service FOGPingHosts start and 1-2 seconds later workstation turned on
Tom Elliott

adn what does the pinghosts.log file show
x23piracy

http://pastebin.com/bGBnVhCz

should i try again? stop pinghosts, shutdown workstation, start pinghosts and see if it turns on immediatelly?

ok did it and it’s the same 2 seconds after starting the pinghosts service the workstation switched on

i can do it a third time if you like
x23piracy

it seems that fogpinghosts i causing this

disable that service, shutdown the problematic workstation, enable the pinghosts service again and exactly 2 seconds later the workstation turns on

i did that 2 times, and i will also happen if i try it a third time
Tom Elliott

okay

i’m looking at ping hosts

but what’s most intriguing

there’s no code to send any packets to unknown hosts

can you do a Teamviewer session?
x23piracy

sure

285 312 065

8120

i will open you a cmd with permanent ping to the workstation that turns on auto
Tom Elliott

no need
x23piracy

so i need to powercfg -h now and you can workaround that also by fog?
Tom Elliott

I cannot workaround by fog.

There is simply no way for me to.

You can workaround it by disabling the ping service

this can be done on the GUI

FOG Configuration Page->FOG Settings->General Settings->FOG_HOST_LOOKUP
x23piracy

powercfg- -h off right?
Tom Elliott

uncheck the box

yes

powercfg -h off
