| 05:50 | <alkisg> Eeeeh I think with that tutorial he's now creating a new *local* user in the clients each time...
| |
| 05:51 | I can't believe that's what he needs...

| 08:21 | <alkisg> For HOSTNAME_PREFIX and HOSTNAME_SUFFIX, I opted to remove them both and use that: https://github.com/ltsp/ltsp/issues/57#issuecomment-548705766
| |
| 08:28 | <uumas> That's actually a great idea. I would probably have used HOSTNAME_SCHEMA, but HOSTNAME works fine.
| |
| 08:29 | <alkisg> In the simple case it'll be HOSTNAME=pc01
| |
| 08:29 | So it would be a big weird to have HOSTNAME_SCHEMA=pc01...
| |
| 08:43 | <uumas> Eh, I don't think it would, but it really doesn't matter.

| 09:43 | <alkisg> bcg: shall I add you to the github team as a developer, to be able to commit directly? Or do you prefer pull requests?
| |
| 09:45 | statler has joined IRC (statler!~Georg@gwrz.lohn24.de) | |
| 10:00 | <bcg> I prefer having direct commit access, although I'll probably use both PRs and direct commits.
| |
| 10:01 | Something like: direct commits for rhel-only, PRs for common code.
| |
| 10:02 | I got go-ahead for ltsp19/rhel8 from my paying customer, but I'm still quite busy on other things + real life.
| |
| 10:02 | <alkisg> bcg: ok, will do; np, take your time, there's no hurry
| |
| 10:03 | It might happen that you start when I'm busy with my phd and I can't help a lot, but I'll help as much as I can then
| |
| 10:04 | <bcg> As you've said, it should be mostly dracut-work.

| 15:03 | <robert45> Hi guys, everytime I start my thin client the OS is asking me to re-setup the machine everytime, is there anyway to prevent this? Any advice is appreciated: https://imgur.com/a/z4GV7z0

| 15:04 | <alkisg> Hi robert45
| |
| 15:04 | This happens because you followed a tutorial the create a new user on the fly each time
| |
| 15:05 | Are you looking to implement guest sessions?
| |
| 15:05 | <robert45> alkisg hey, what do you mean by guest sessions?
| |
| 15:06 | <alkisg> It usually means "accounts where everything is deleted on logout"
| |
| 15:06 | No files or settings saved
| |
| 15:07 | <robert45> alkisg If things can be saved on every logout it would be great. I dont need much info saved, maybe Firefox settings, bookmarks and stuff
| |
| 15:08 | <alkisg> robert45: then you don't want guest sessions. Can you paste again the tutorial that you followed?
| |
| 15:09 | I think you were trying to create a "template account" and you followed the wrong tutorial and implemented "new account each time"
| |
| 15:12 | <robert45> alkisg I didnt follow any tutorial. Actually this was a ltsp upgrade, I ran a couple of commands to move my OS dist-upgrade into the client ltsp, I didnt touch any file except for the ones you told me yesterday (not sure if you remember but the client wasnt booting and throwing errors). The rest is using the config files from the previous version I think, Im happy to paste any config you need
| |
| 15:14 | <alkisg> robert45: if you see this screen on each login, this means that your /home/username isn't saved https://imgur.com/a/z4GV7z0
| |
| 15:14 | I think it'd be faster if you VNC to me so that I get a quick look
| |
| 15:14 | !vnc-dide
| |
| 15:14 | <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.
| |
| 15:23 | <robert45> Let me see if I can do that. Would you automatically connect or do I have to tell you when I run this command?
| |
| 15:28 | alkisg I ran you rcommand but its throwing an error: https://paste.ubuntu.com/p/Fsbnfdt33y/
| |
| 15:43 | <alkisg> robert45: are you using wayland?
| |
| 15:44 | robert45: if yes, logout and select "ubuntu" at login, not "ubuntu on wayland"
| |
| 15:44 | Also don't use ssh or virtual consoles; run this as a normal user in the server gui
| |
| 15:44 | (or even in the client gui)
| |
| 15:45 | <robert45> alkisg not sure what wayland means. Im running ubuntu 18 on a xenserver vm with no gui
| |
| 15:45 | <alkisg> Wayland is what replaced xorg
| |
| 15:46 | Do you have a gui in your own pc? Is it linux? If yes, run that from there
| |
| 15:46 | Or run it from the client
| |
| 15:47 | <robert45> alkisg my own pc runs windows, ltsp client doesnt have internet
| |
| 15:48 | <alkisg> !uvnc-dide
| |
| 15:48 | <ltsp> uvnc-dide: To share your *Windows* screen with me over VNC, download and run this: http://alkisg.mysch.gr/downloads/uvnc-dide.exe
| |
| 15:53 | <robert45> alkisg ok so its installed, what now?
| |
| 15:53 | <alkisg> Run it and click the connect button
| |
| 15:59 | robert45: back
| |
| 16:00 | <robert45> alkisg thanks, what should we do?
| |
| 16:00 | <alkisg> I can't easily get access to the client through that. Remarks:
| |
| 16:00 | lts.conf doesn't go to /opt/ltsp/i386/etc but to /var/lib/tftpboot, so that you don't need to update image when you edit it,
| |
| 16:00 | now, about the problem, I think that your /home/username doesn't get mounted, if you see that every time
| |
| 16:00 | Try this:
| |
| 16:01 | create a file in the user documents, logout, reboot, login again, see if the file exists
| |
| 16:01 | If the file doesn't exist, then your /home/username isn't mounted from the server for some reason
| |
| 16:01 | <robert45> alkisg Ok, understood
| |
| 16:01 | alkisg Ok, let me try that now
| |
| 16:01 | <alkisg> ok
| |
| 16:09 | <robert45> alkisg Confirmed. Files are gone
| |
| 16:11 | What should I do? The previous version was working just fine, preserving users and files
| |
| 16:13 | there is not much info on the internet regarding this issue
| |
| 16:25 | <alkisg> robert45: what previous version? You're using the old ltsp, called ltsp5
| |
| 16:25 | The new ltsp is called ltsp19, you don't have that
| |
| 16:26 | I would need access to the client to troubleshoot this
| |
| 16:26 | Preferably via epoptes, but you don't have a gui header, so I guess normal client access will have to do
| |
| 16:26 | Or you could just install the new version...
| |
| 16:34 | !install
| |
| 16:34 | <ltsp> install: To install LTSP19+: https://ltsp.github.io/docs/installation. To install LTSP5: http://wiki.ltsp.org/wiki/Installation/Ubuntu for Ubuntu, or http://wiki.ltsp.org/wiki/Installation for other distributions
| |
| 17:08 | <robert45> alkisg sorry, I meant to say that I upgraded my ubuntu to version 18 and updated all the packages to their latest apt release. I dont wish to run another upgrade as its consuming lots of my time. Is there anyway I can troubleshoot this?
| |
| 17:16 | alkisg I can try to setup the vnc on the thin client if you wish to take a look
| |
| 17:16 | any help is very appreciated

| 18:02 | <alkisg> robert45: sure, try to run that command from the fat client
| |
| 18:05 | Btw setting up a chrootless ltsp takes 10 minutes after initial OS installation
| |
| 18:30 | statler has left IRC (statler!~Georg@gwrz.lohn24.de, Remote host closed the connection) | |
| 18:38 | <robert45> alkisg I have installed x11vnc in the ltsp server and regenerated the ltsp image. Im now rebooting
| |
| 18:40 | alkisg Meanwhile I was reading a help.ubuntu.com article about LTSP. Could it be because I dont have MOUNT_LOCAL_REAL_HOME setup in lts.conf ?
| |
| 18:51 | alkisg I have ran the command, can you check?
| |
| 18:52 | https://imgur.com/a/f6XS4Uc
| |
| 18:53 | <alkisg> moment, be there in 10 mins
| |
| 18:54 | <robert45> sure
| |
| 18:55 | alkisg Also if you can chat over here it would be great as Im no longer on the screen
| |
| 18:58 | <alkisg> robert45: ok back
| |
| 18:58 | So yes this client doesn't have home mounted
| |
| 18:59 | But I dont' have access to the server anymore to compare
| |
| 18:59 | <robert45> alkisg hold on, let me give you access
| |
| 18:59 | <alkisg> Can you see the client screen? Can we ssh to the server from there?
| |
| 19:00 | <robert45> alkisg You have access to the server now
| |
| 19:00 | alkisg No, I cant
| |
| 19:01 | <alkisg> Somehow you're managing to run gdm instead of lightdm
| |
| 19:01 | So this can't work
| |
| 19:01 | <robert45> alkisg Im not sure what that means, my ltsp knowledge is very limited
| |
| 19:01 | <alkisg> gdm is the gnome display manager, it's not ltsp
| |
| 19:02 | That's why it doesn't work, because you're not running the ltsp login screen but the gnome login screen
| |
| 19:02 | I can't see how though...
| |
| 19:02 | <robert45> alkisg oh, I dont mind switching to lightdm if that is the case
| |
| 19:02 | <alkisg> lightdm won't work either
| |
| 19:02 | LTSP needs LDM
| |
| 19:02 | Its own display manager
| |
| 19:04 | Also... you're somehow running wayland or something... yet you have vnc... very confusing
| |
| 19:05 | robert45: anyway your setup is rather broken, and since it's the old ltsp it's not of interest to troubleshoot it
| |
| 19:05 | I'd suggest to either reinstall using the chrootless method which takes 10 minutes after OS installation, or with the new ltsp19
| |
| 19:05 | <robert45> alkisg I installed some gnome packages when I was upgrading the OS, not sure if its related
| |
| 19:05 | <alkisg> Maybe. Somehow gdm is getting launched while it shouldn't be
| |
| 19:06 | <mwalters> could he have dist-upgraded all the way up to 19.04?
| |
| 19:06 | <alkisg> He has 18.04.3 in the client
| |
| 19:07 | Initial chroot installation is probably trusty: # deb cdrom:[Ubuntu 14.04 LTS _Trusty Tahr_ - Release amd64 (20140417)]/ trusty main restricted
| |
| 19:07 | 14.04
| |
| 19:08 | <mwalters> strange stuff!
| |
| 19:08 | <robert45> alkisg If I dont have any other choice then I can try that. So I have to OS reload with Ubuntu 18 and install ltsp?
| |
| 19:09 | <alkisg> !install
| |
| 19:09 | <ltsp> install: To install LTSP19+: https://ltsp.github.io/docs/installation. To install LTSP5: http://wiki.ltsp.org/wiki/Installation/Ubuntu for Ubuntu, or http://wiki.ltsp.org/wiki/Installation for other distributions
| |
| 19:09 | <alkisg> One of these, yes
| |
| 19:09 | <robert45> alkisg should we try removing all the gnome packages first?
| |
| 19:10 | <alkisg> I give free support in many cases, especially if it means fixing ltsp bugs; but this is the old ltsp version and it's just a broken installation, not an ltsp issue; so it's not "interesting" to help there. You can hire me to try to troubleshoot it if you want, but I think you should just reinstall.
| |
| 19:10 | <robert45> alkisg, ok. Going to try reinstall now
| |
| 19:10 | <alkisg> ok
| |
| 19:12 | <robert45> alkisg thanks so much for your free support so far, its very appreciated
| |
| 19:12 | <alkisg> You're welcome
| |
| 19:12 | If you want, state your requirements, so that we give better advice on what to install etc
| |
| 19:13 | In general, installing ubuntu 18.04 mate desktop edition on the server, and then installing ltsp19 on top of it in chrootless mode, is the easiest and fastest setup
| |
| 19:15 | <robert45> alkisg if its easier to install configure ltsp19 instead of ltsp5, then I will give ltsp19 a try
| |
| 19:15 | <alkisg> chrootless is about the same
| |
| 19:16 | The difference is that I dont care to fix ltsp5 bugs but I care to fix ltsp19 bugs :D
| |
| 19:16 | <robert45> alkisg ok, sure
| |
| 19:16 | alkisg meanwhile Im deploy a new vm to test the new ltsp. I found I have LDM_SESSION = "gnome-session --session=cairo-dock" inside lts.conf, could be the reason of the gnome session you said?
| |
| 19:17 | <alkisg> No; in your case gdm was running instead of ldm, which can't be done via lts.conf
| |
| 19:17 | It might be some new systemd service that ran gdm without ltsp5 managing to block it
| |
| 19:18 | <robert45> alkisg ok got it
