| 06:41 | <Trendzetter> @£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.

| 06:58 | kjackal_ has joined IRC (kjackal_!~quassel@185.156.60.18) | |
| 07:04 | <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

| 08:01 | <alkisg_android> 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 | Statler has left IRC (Statler!~Georg@p579FEE12.dip0.t-ipconnect.de, Remote host closed the connection) | |
| 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 | <alkisg_android> np

| 09:37 | GodFather has joined IRC (GodFather!~rcc@47.33.250.142) | |
| 09:39 | <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?

| 09:57 | <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

| 10:26 | <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

| 12:38 | <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.
| |
| 12:49 | vagrantc has left IRC (vagrantc!~vagrant@unaffiliated/vagrantc, Quit: leaving) | |

| 13:14 | <Trendzetter> @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.
