when I shutdown the epoptes clients, them really restart

Asked by migue

I have a classroom with 22 epoptes clients (linux mint 17.2 xfce) and a server with Linux Mint Cinnamon 17.3 and epoptes 0.5.10.

When I send shutdown signal to the clients from the epoptes server, some clients do not obey, instead make a restart. Then I order a second shutdown, then they finally do as intended.

(In the morning I start the clients whit the WOL start tool of the epoptes server)

Sorry for my poor english

If they all have the same Desktop Environment, and some of them properly shut down, and others reboot instead,
then it doesn't sound related to epoptes, but it sounds like a bug in the DE.

Can you try to log them out first, and *then* invoke a shutdown?

Hi Alkis, thanks for your response. I tried your suggestion, but it did not work for me.
Additionally I note this: when I power the clients on by pushing the power button (not by WOL) , and later I shutdown them from the epoptes server, then they power off correctly. Have this any significance for you?

regards and many thanks,
migue

I think this proves that it's not related to epoptes, but to something else, like the kernel or the specific module or the init system or the bios etc. Something is buggy there and causes a crash/reboot while trying to shut down.
You should be able to reproduce it manually if you try enough times to shut down the clients from the menus, without using epoptes at all.

Since the bug is not in the epoptes code, I'm marking the question as invalid in epoptes, please reopen it if you cannot reproduce it without using epoptes.
