i got a problem! anyone can help?
05:37
<alkisg>
!ask
05:37
<ltsp`>
ask: Don't ask to ask a question, simply ask it, and if someone knows the answer, they'll respond. Please hang around for at least a full hour after asking a question, as not everybody constantly monitors the channel.
05:38
<popsy^popsyMint>
when i monitor user, it doesn't work!
05:38
<alkisg>
Which distro/version?
05:38
<popsy^popsyMint>
Linux Mint 18.3 Cinnamon
05:39
<alkisg>
Are you using ltsp, netbooted clients?
05:39
<popsy^popsyMint>
yes
05:39
<alkisg>
It sounds like you didn't install epoptes-client in the chroot
05:39
Do you see the clients before login, like blue/green monitor images?
05:40
Check the images there: http://ts.sch.gr/mediawiki/images/b/b3/0.5.7_epoptes_startup.png
05:40
<popsy^popsyMint>
i'll check it
05:40
<alkisg>
The green/blue ones, do you see images like those?
05:43
<popsy^popsyMint>
nope
05:44
<alkisg>
OK, then you need to install epoptes-client in your chroot, and re-run ltsp-update-image
05:44
epoptes.org/installation
05:44
<popsy^popsyMint>
it just their screen but when I click to broadcast > monitor user
05:44
there's no window to show
05:47
<alkisg>
I understood and I told you the solution

<cvillasboa>
Well, once again, I apologize for disturbing again, but I still have some doubts, now I have a problem, I am using a laptop as a client, the laptop supports PXE when the start finds the IP address of the LTSP server. and also the name of the file, but after finishing all this process I receive a message of "There is no boot device", I want to know if it happened to someone the same
14:20
Actually, the message I receive is
14:20
"no bootable device"
14:21
<||cw>
the messages preceding are the important ones
14:23
<cvillasboa>
It is worth mentioning that my laptop does not have a hard drive, because I took it out, I understand that it is not necessary
14:23
<||cw>
that's correct
14:23
"no bootable device" is usually a BIOS message, so the messages before that would be what shows why the PXE won't boot
14:27gdi2k has left IRC (gdi2k!~gdi2k@180.191.113.3, Ping timeout: 240 seconds)
14:27
<alkisg>
cvillasboa: that probably means you didn't configure your server correctly and no client can boot
14:27
<cvillasboa>
I write you the messages that appear previously
14:27
<alkisg>
What's the output of `sudo ltsp-info | nc termbin.com 9999` ?
14:33
<cvillasboa>
Station IP address is 192.168.67.80 The Server IP address is 192.168.67.22 NBP file name is /ltsp/i386/pxelinux.0 NBP filesize is 42788 Downloading NBP file ......... Succed to download NBP file.
14:34
<alkisg>
What is NBP?
14:34
Is the client UEFI? Configure it in legacy mode if so
14:35
<cvillasboa>
This appears during the start, but as mentioned above, I receive the message from.. " no bootable device"
14:35
<alkisg>
(05:27:58 μμ) alkisg: What's the output of `sudo ltsp-info | nc termbin.com 9999` ?
14:37
<cvillasboa>
`sudo ltsp-info | nc termbin.com 9999` , this should run on my server, is that correct?
14:38kjackal has joined IRC (kjackal!~quassel@50-201-118-110-static.hfc.comcastbusiness.net)

15:53
yes*
15:59
As suggested by Alkisg, run this command, `sudo ltsp-info | nc termbin.com 9999`, whose result was the following ...
15:59
No LSB modules are aivalable http://termbin.com/2uxq
16:00
I don't understand very well what it's for
16:02
<||cw>
it just shows that you do in fact have an image.
16:02
<cvillasboa>
I understand

16:23
<||cw>
what method did you use to install/configure the server? if it's new, maybe start over from scratch with ltsp-manager.
16:23
unless you really want to get into debugging PXE and such

alexxtasi[m]: ltsp its recommended for productions, like company, database programm etc ...
16:31
<alkisg>
cvillasboa: is this the first time you're trying ltsp? did you manage to boot any clients at all?
16:38
Trendzetter: thank you dear, much appreciated. Please do remind me next time you'll need help, to do a bit more than usual. :)
16:40
<mmarconm>
alkisg: ltsp its recommended for productions, like company, database programm etc
16:40
<alkisg>
mmarconm: is this a question? Sure, if it fits your needs, you can use it in production. It's already used in many similar environments.
16:41
<mmarconm>
alkisg: ohh thanks, but with fat client or thin client ? a client of my asked about that, he want on a supermarket
16:41
<alkisg>
Fat clients are better
16:47
<mmarconm>
Debian with mate or ubuntu lxde, mate ?
16:51
<alkisg>
mmarconm: currently, the one more tested is ubuntu 16.04 mate
16:51
In September, it will be ubuntu 18.04 mate
16:51
!ltsp-pnp
16:51
<ltsp`>
ltsp-pnp: ltsp-pnp is the recommented method to install and maintain LTSP for "usual" setups. Since it doesn't involve chroots, it requires little to no command line to maintain it. It automatically supports both thin and fat ltsp clients. https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
16:51
<alkisg>
!ltsp-manager
16:51
<ltsp`>
ltsp-manager: LTSP Manager is a GUI tool that makes LTSP maintenance easy. It's the recommended way to install LTSP in common setups. More info: http://wiki.ltsp.org/wiki/Ltsp-manager
16:51
<alkisg>
Follow one of those 2 methods
16:53

||cw: first install the ltsp-server-standalone and then in ltsp-build-client I am using ubuntu as ltsp server, followed a tutorial of them
18:11
<||cw>
cvillasboa: try ltps-manager
18:11
ltsp-manager
18:11
also,which guide? maybe it was old, or not well tested and they missed something
18:12
<cvillasboa>
It's ok, I'll do it
18:17
alkisg: Yes, it's the first time I try, and I still can not lift it, I'll try ltsp-manager as it says ||cw
18:19
<bwicksall>
Hello, I'm new to LTSP. I have done 3 installs following the LTSP-PNP method at https://wiki.debian.org/LTSP/Howto . My clients randomly get a black screen when booting or at logoff. It looks like ldm-script init is hung. If I kill the script the logon appears.
18:20
I'm running Debian 9
18:22
<gbaman>
That's interesting bwicksall... As I have been getting similar with Debian 9 as well (on Raspberry Pi) and thought might just be me or Pis...
18:22
But works no issue on Debian 8
18:24
<vagrantc>
bug reports appreciated
18:24
<bwicksall>
Looks like nbd is having issues when it is called from the ldm init script
18:25
Noob here. Where do I report bugs?
18:26
<alkisg>
!nbd
18:26
<ltsp`>
I do not know about 'nbd', but I do know about these similar topics: 'disable-nbd-proxy', 'nbd-proxy', 'nbd-compression', 'quick-nbd-tests', 'nbd-client', 'nbd-server-bug', 'nbd-trusty-bug', 'nbd-client-breaks-nm', 'nbd-bug', 'nbd-checkupdate'
18:26
<alkisg>
!nbd-checkupdate
18:26
<ltsp`>
nbd-checkupdate: To avoid bug https://github.com/NetworkBlockDevice/nbd/issues/59, put this in lts.conf: INIT_COMMAND_RM_NBD_CHECKUPDATE="rm -rf /usr/share/ldm/rc.d/I01-nbd-checkupdate"
18:26
<alkisg>
bwicksall: see if it's that ^ issue that affects you
18:27
<bwicksall>
I'll do that now. Was leaning toward that already
18:30
<cvillasboa>
||cw: the guide I followed is really a video, it shows that the installation on Ubuntu 16.04 does not seem to be that old, and also uses a laptop as a client
18:30
<alkisg>
cvillasboa: I have 5 mins of availability, if you're here I could have a lookover vnc
18:30
!vnc-dide
18:30
<ltsp`>
vnc-dide: To share your screen with me, run this: sudo apt-get --yes install x11vnc; x11vnc -connect srv1-dide.ioa.sch.gr - this is a reverse connection, it doesn't need port forwarding etc.
18:32
<bwicksall>
ltsp: looks like that fixed my issue. Just did several random restarts and it worked every time
18:32
<alkisg>
bwicksall: ltsp is a bot that we invoke to show notes
18:33
It's not a person; I used it to show you the link
18:34
<gbaman>
I will give it a go as well and see if it fixes it for Raspbian Stretch, that one has had me scratching my head for quite a while now
18:34
<vagrantc>
alkisg: should we just remove the nbd-checkupdate functionality? it seems to cause more problems than it solves...
18:35
alkisg: or disable by default or something
18:35
<alkisg>
vagrantc: for september, I'll test adding a small delay there
18:35
I think even 1 sec solves the issue
18:35
<bwicksall>
alkisg: Thanks for the help!
18:35
<alkisg>
I can't say that I like the functionality, but adding 1 sec delay at that point doesn't sound that bad
18:35
bwicksall: np
18:36
<cvillasboa>
alkisg: I'm leaving work right now, we could do it tomorrow, depending on your time ..
18:36
<alkisg>
cvillasboa: I'll be around 8:30 - 11:30 Greek timezone tomorrow
18:36
If you can find me then, np
18:37
(morning)
18:38
<vagrantc>
alkisg: "sleep" workarounds generally indicate real problems that minor things can change how much sleep you need
18:39
<alkisg>
vagrantc: indeed; the proper solution will come with reporting the problem to the kernel nbd module
18:39
<cvillasboa>
I do not know what time it would be, I'm in Paraguay and now it's 14:37
18:39
<alkisg>
I reported it to the client-side nbd github repo, which wasn't the correct place, but I didn't take the time to properly report it. Hopefully someone else will.
18:39
cvillasboa: now it's 21:40 here
18:39
<cvillasboa>
in case it serves as a reference
18:40
ok, then the schedule adjusts
18:42
thanks alkisg
18:44
I will keep trying as it says ||cw anyway
18:45
thanks to you also ||cw
18:45
<||cw>
i'm not a fan of video guides, too easy to miss something. use the official ltsp-manage guide and it's pretty easy
18:47
<cvillasboa>
you're right, I'll follow the suggested guide
18:54
<gbaman>
So alksig, what is that disabling then? What is nbd-checkupdate actually for?
