<mwalters>
alkisg: looks like there's no epoptes command line API right now? (e.g., log off someone via a command)
13:45
like 90% of our users leave their machines logged in overnight, thinking about logging everyone off around 0200 or so to make sure they have updated images
13:58
<alkisg>
mwalters: cron?
14:01
You can even launch an "at" command from the epoptes execute dialog...
14:02
<mwalters>
ideally cron, yes
14:03
oh
14:03
I get what you're saying... a cron job in the image
14:04
I can't keep up with so many layers of abstraction @_@
14:04
One of these days my sanity is going to be abstracted away
14:05
But yes, thanks... that sounds much less complicated than what I was thinking of doing ;)
14:08
I dropped that CPU idlestate script in last night... best I can tell, I think it may have fixed my J1900s freezing
14:08
Also, I dropped another with `chvt 7` in there, which seems to have solved certain clients sometimes booting to tty1 (I only use tty7 for clients)
14:10
I had to modified the intel_cstate script from the one that I found, my C6 states were named a bit different from the one in that bug thread, I can share if anyone runs into that issue... J1900s are pretty old now, though
14:21
<mads2>
Any idea why my clients hang on "Stop job is running for Raise network interfaces" when I try to shutdown them? I tried "shutdown -h now", "halt" and the power off in the GUI, all with the same result.

<alkisg>
(04:03:48 PM) mwalters: I get what you're saying... a cron job in the image ==> or in lts.conf
14:25
mads2: are you using the greek schools ppa?
14:26
<mads2>
@alkisg: yes. Ubuntu LTS and greek ppa
14:26
<alkisg>
mads2: which ubuntu lts?
14:26
16, 18?
14:27
<mads2>
18
14:27
<alkisg>
chroot or chrootless?
14:27
<mads2>
chroot, back to NFS
14:28
<alkisg>
And are you sure that your chroot does have the ppa?
14:28
What's the output of sudo ltsp-info?
14:28
<mads2>
I'm not in my lab right now. But I'm sure.
14:28
Doing some research, it may not be related to the LTSP
14:29
but to systemd or some network driver
14:29
<alkisg>
That symptoms is seen when one does not have the ppa
14:29
I solved it and uploaded a new version to the ppa
14:29
But if you say you are SURE... let's continue when you're at the lab
14:29
<mads2>
really? recently? I'll try to upgrade the system when I get there
14:30
<alkisg>
In late august
14:30
<mads2>
unnn. So it's probably not the problem.
14:31
but I will verify it just to be sure sure

<alkisg>
It's very usual that people think they have the ppa in the chroot, but they don't
14:31
I'll wait for the output of ltsp-info first
14:31
<mads2>
ok. Thanks!

<Natureshadow>
On an LTSP client with two monitors, how do I make ldm show on both?
16:00
<alkisg>
You would run a XRANDR_COMMAND in lts.conf to clone them
16:00
e.g. xrandr --output LVDS-1 --same-as VGA-1 or something

<Natureshadow>
Ah, that variable was what I was looking for
16:04
Thanks!

<uumas>
Is it possible to specify a group of machines by hostname in lts.conf, eg. I have machines lab10, lab11... and hallway20, hallway21...
17:33
I could just specify a group called lab and add every machine's mac to it with LIKE but that's a lot of throuble considering I have that done already in the dhcp server config
17:34
Also, is it possible to allow only members of a specific group to log in to a machine or do I need to specify every username individually?
17:35
<alkisg>
For (1), [lab*] is supposed to work, but I'm not sure that it does work
17:35
For (2), I don't think so, of course unless you write a couple of lines of code yourself
17:37
<uumas>
I tried just with having lab20 there, but the settings under it didn't get applied on the client
17:37
So it seems the config doesn't recognize hostnames at all
17:39
<alkisg>
Are you using ipappend 2 or 3?
17:43
<uumas>
2
17:43
I was the one having problems with exactly that a few days ago
17:43
<alkisg>
Right
17:43
There was a bug report in launchpad about that hostname thing you mention now
17:44
I think it wasn't handled in the correct order, but I don't think anyone fixed it. I know I didn't. :)
17:44
I.e. some people actually set HOSTNAME in lts.conf
17:44
So it should be possible to set it either at dhcp, and then use it in lts.conf, or at lts.conf... and now it appears only the latter works
17:45
<uumas>
Well, alright, I guess I'll have to just do it manually for now
17:46
Btw. What is the currently up-to-date ltsp repo?
17:47
<alkisg>
The greek schools ppa for ubuntu
17:47
And debian testing for debian
17:48
<uumas>
Oh, I meant the (github?) repository
