@£Hyperbyte: I managed to set the wake-on-lan settings on the network interface and it's working now for some types of my handware. If I modify the added rc script to get the name of the primary network interface I should be able to set the flags on the other types of handware.

<Hyperbyte>
Trendzetter, so you want to know how to read the name of the primary network interface into a variable in a bash script.
07:05
That question however is not LTSP related. Plus I'm sure Google can help you with that.
07:05
If not, seek general Ubuntu support or even bash scripting support channels.
07:05
<Trendzetter>
if you have decent function ready I would use it but it's not a question
07:05
<Hyperbyte>
I don't.
07:05
<Trendzetter>
just wanted to let you know that I am making progress
07:06
almost there :D

Trendzetter: epoptes automatically enables wol for clients, are you using epoptes?
08:01
<Trendzetter>
it didn't work, I am willing to look into it if you want debugging info
08:02
<alkisg_android>
Also, if you're using mate, it blocks wol, and you need to uninstall tlp to unblock it
08:02
<Trendzetter>
I just configured tlp
08:02
to allow wol
08:02
<alkisg_android>
did you disable tlp?
08:02
ok
08:02
<Trendzetter>
there are some settings in /etc/default/tlp
08:02
<alkisg_android>
distro/version?
08:03
<Trendzetter>
the clients are ubuntu 16.04.2
08:03
the server is debian 8
08:03
<alkisg_android>
ok, boot a client, open a root shell from epoptes, and check the output of ethtool
08:04
<Trendzetter>
epoptes is all on 0.5.10 I think
08:04
<alkisg_android>
is wol enabled there?
08:05
<al-geo>
somebody give me please link to tutorial to how to make debian fat clients on ubuntu 16.04 server
08:07
<alkisg_android>
make a chroot in a debian server and copy it to the ubuntu server
08:07
<al-geo>
or good tutorial how to make ltsp-server with dnsmasq on debian

08:08
<alkisg_android>
i dont think there's a tutorial on how to do it from ubuntu, you'd need a weird ltsp-build-client command with VENDOR=Ubuntu etc
08:09
google for debian ltsp-pnp for that
08:10
https://wiki.debian.org/LTSP/Howto
08:10
<al-geo>
yes but ltsp-pnp with fat client is not possible write?
08:10
<alkisg_android>
of course it is
08:10
fat clients are why ltsp-pnp exists
08:11
<al-geo>
? ltsp-update-image --cleanup / makes fat clients?
08:11
<alkisg_android>
yes
08:12
<al-geo>
ok thanks. earlier i try this tutor but failed. i will try again
08:12
<alkisg_android>
ok
08:19
<Trendzetter>
@alkisg: I think the issue with my epoptes server now is that it does not have a decent network interface. This esxi virtual hardware and driver does not support sending wol packets. When I do "ethtool -s eth0 wol g" as root it says "operation not supported.". I had this issue with an other vm too where I am trying to send the wol packet. I needed to replace the virtual network interface with vmxnet3 instead of E1000.
08:20
<alkisg_android>
you dont need to enable wol on the server
08:21
run ethtool via epoptes open terminal feature on the client, not on the serber
08:23
<Trendzetter>
i did and since I run an rc script that does ethtool -s <INTERFACE NAME> wol g the clients can wake up when sending a packet from a machine that has a decent network interface and has the "supports wake on" setting set to letter g instead of d.
08:24
the clients now have wake on: g when I run ethtool
08:24
<alkisg_android>
epoptes and tlp have such scripts too, so delete your script
08:24
<Trendzetter>
I tried and it didn't work
08:25
<alkisg_android>
we need to see if you properly disabled tlp, otherwise it disables wol on shutdown
08:25
if it didnt work then you didnt disable tlp properly
08:26
RM_SYSTEM_SERVICES=tlp in lts.conf
08:27
<Trendzetter>
ok. I will try this and disable the script. I first need to finish a few things. I will send an update later on today.
08:28

<Trendzetter>
I can confirm that disabling tlp sets the "wake on" to letter g instead of d (so WOL is working now) on the client network interfaces. Do I risk higher power consumption as a result or any other downsides to this approach?

<Trendzetter>
the clients are now booting nicely on WOL command but epoptes can't wake them because the clients are in a different subnet. I can set the bios to allow wake from LAN/WAN but then I have to make sure that epoptes knows how to send the magic packet to the right subnet.
09:58
I will first check if wol is allowed from lan and wan on all the test clients

<Trendzetter>
if I want to use epoptes gui to wake the client I need to get up a forwarding of magic packets from 1 subnet to another. I am still figuring this out
10:50
would it be doable to configure epoptes gui to take into account forwarding of magic packets for wol to a specific router? I am now figuring out which of my routers support forwarding of wol. The tp-link I have in every location doesn't allow forwarding to a broadcast address ...
10:51
maybe the old dlink gateways would do but I am not using those in all locations

<Trendzetter>
another update: I can now wake my test clients using the ltsp server as router to forward the magic packets from the wan to the lan. If I can set the router ip for each client it should be possible to send WOL directly from the epoptes gui
12:40
I will now try to install dell command configure in the image to tune the bios remotely on all clients.

even better would be if I could set a router ip for each group

@alkisg: To run dell command configure (enterprise management tools) I would need to run a 64bit version of ubuntu16.04. Any suggestions on how to migrate the quickest from the exact same setup 32bit? Since the time we started using ltsp some of the oldest clients have been discontinued and all of them should have 64bit cpu's.

i am downloading the image now, I guess doing a new setup will be necessary. Then I will have to copy some files from /home and /etc. Not sure how to mirror the software selection.
