| 12:40 | <MacMilanzi> Hello, Its me again, having an issue with the ltsp clients on debian after autologin not taking changes. after the autologin on the thin client when i run "mount | grep home " it shows nothing.
| |
| 12:42 | After auto login on the clients, changes that i have made for that user on the server are not reflecting on the clients with autologin.
| |
| 12:43 | <alkisg> MacMilanzi: after autologin, what's the output of this command on the client?
| |
| 12:43 | mount | grep home
| |
| 12:44 | If it's blank, it means sshfs didn't work properly
| |
| 12:44 | <MacMilanzi> Just right after the autologin, the output is nothing.
| |
| 12:47 | But when the screen locks and i login with password, the output is this this: wtp--ows1@server: on /home/wtp-ows1 type fuse.sshfs

| 12:49 | <MacMilanzi> So how do i make sshfs to work properly?

| 13:17 | <apple> Good day!
| |
| 13:17 | Try to get debian 11 LXDE working per a vm via ProxMox. Stumbles when the client can't bring up the network.
| |
| 13:17 | Similar installs with gnome or mate desktop do work.
| |
| 13:17 | But I want the small foot print of LXDE.
| |
| 13:19 | I've got a screen shot but how do we pass in those without offending IRC?
| |
| 13:21 | Trying* that is.
| |
| 13:35 | <MacMilanzi> so you are saying i should try the same setup but with debain 11 LXDE correct?
| |
| 13:36 | apple, mine right now has gnome, and quick fix with that?
| |
| 13:37 | **any quick fix with that?

| 14:16 | <alkisg> apple: you can put it in imgur.com
| |
| 14:16 | !photo
| |
| 14:16 | <ltspbot> I do not know about 'photo', but I do know about these similar topics: 'paste'
| |
| 14:17 | <alkisg> !screenshot
| |
| 14:17 | <ltspbot> screenshot: to upload a screenshot use a site like https://prnt.sc/ or https://snag.gy/ and then paste the URL here
| |
| 14:25 | <alkisg> MacMilanzi: we should get the logs of the first login

| 14:26 | <alkisg> Reboot a client press control + alt + f2 and try to login there
| |
| 14:26 | <eu^ip-209-124-24> Okay
| |
| 14:27 | <apple> Does this work? https://photos.app.goo.gl/2FjFpnhSuVecsJCr5
| |
| 14:28 | Greetings MacMilanszi, no, didn't mean you. I do see now that you are also trying Debian.
| |
| 14:31 | <alkisg> apple: I'm guessing that LXDE has some weird networking service that discards the ltsp client IP
| |
| 14:32 | Try this in ltsp.conf: MASK_SYSTEM_SERVICES=ifupdown-pre
| |
| 14:34 | <apple> https://www.irccloud.com/pastebin/uGq4BGnW
| |
| 14:35 | <alkisg> Heh, irccloud created a pastebin for 2 lines of chat :)
| |
| 14:37 | <eu^ip-209-124-24> alkisg, i have logged in from the terminal on the client, control + alt+ f2
| |
| 14:37 | eu^ip-209-124-24 is now known as MacMilanzi | |
| 14:37 | <alkisg> Did you see any error messages or warnings?
| |
| 14:38 | <MacMilanzi> No
| |
| 14:38 | <alkisg> Is home mounted now?
| |
| 14:39 | <MacMilanzi> yes
| |
| 14:39 | <alkisg> Is that GNOME?
| |
| 14:39 | <MacMilanzi> Yes
| |
| 14:40 | <alkisg> Then I can only assume that gdm doesn't call pam properly for autologin
| |
| 14:41 | I would need to see it with screen sharing but I'm not available right now
| |
| 14:41 | <MacMilanzi> Okay, when will you be available?
| |
| 14:42 | <alkisg> The best time to find me is 08:30 to 12:30 in Greek timezone
| |
| 14:44 | <MacMilanzi> Okay, thanks
| |
| 14:44 | <alkisg> 👍
| |
| 14:47 | <MacMilanzi> In the meantime, any suggestions where i would go looking or digging?
| |
| 14:48 | <alkisg> You can try to replace gdm with lightdm
| |
| 14:48 | apt install lightdm
| |
| 14:51 | <MacMilanzi> Alright, thanks I will try that right now.
| |
| 14:56 | vagrantc has joined IRC (vagrantc!~vagrant@2600:3c01:e000:21:7:77:0:20) | |
| 15:07 | <MacMilanzi> After apt install lightdm, when i boot up the client on a quad monitors, one monitor is flickering and as for auto login is failing it keeps flashing the "Username, login" card
| |
| 15:18 | <apple> https://www.irccloud.com/pastebin/QXze7bNc
| |
| 15:28 | <MacMilanzi> My clients are not able to receive IP offers after lightdm install. Is there a setting that i have to enable for ltsp to work with lightdm?
| |
| 15:31 | It wasn't lightdm sorry, figured the ip part out.

| 15:34 | woernie has joined IRC (woernie!~werner@p5b2962ea.dip0.t-ipconnect.de) | |
| 15:56 | <alkisg> apple: your messages show up as pastes; try to send a single line each time instead of two
| |
| 15:56 | MacMilanzi: did lightdm work?
| |
| 16:08 | <MacMilanzi> alkisg: it is not working in lightdm, is there a config line in lightdm that i have to enable to make it work? Its just blinking when i use autologin with lightdm
| |
| 16:09 | alkisg : when i boot up the client it just blinks with the "Username , login" card.
| |
| 16:12 | oh207_ has joined IRC (oh207_!~oh207@pool-72-69-11-48.nycmny.fios.verizon.net) | |
| 16:19 | <apple> Thanks, trying a single line.
| |
| 16:23 | <alkisg> MacMilanzi: after the client boots, type: cat /etc/lightdm/lightdm.conf | nc termbin.com 9999
| |
| 16:24 | It should show your autologin there if properly enabled
| |
| 16:24 | apple: single line works :)
| |
| 16:24 | MacMilanzi: do you have epoptes installed? If so, I can have a quick look over VNC
| |
| 16:26 | !vnc-edide
| |
| 16:26 | <ltspbot> vnc-edide: To share your screen with me, open Epoptes → Help menu → Remote support → Host: srv1-dide.ioa.sch.gr, and click the Connect button
| |
| 16:27 | <MacMilanzi> On the client? or server?
| |
| 16:28 | <alkisg> On the server, so that we have access to the client even before login
| |
| 16:28 | <MacMilanzi> Okay
| |
| 16:30 | <alkisg> MacMilanzi: first of all, you need a different account per client
| |
| 16:30 | If you login with the same account in multiple clients or the server, at the same time, you corrupt dconf and other files
| |
| 16:31 | Desktop environments are not designed for multiple simultaneous logins
| |
| 16:31 | <MacMilanzi> Okay, right now i have one client running for testing. Once it works i will create different accounts for the clients.
| |
| 16:32 | <alkisg> Second, lightdm isn't installed in the image
| |
| 16:37 | oh207 has joined IRC (oh207!~oh207@pool-72-69-11-48.nycmny.fios.verizon.net) | |

| 16:41 | <alkisg> OK lightdm is installed, but I checked a client that hasn't rebooted yet
| |
| 16:41 | <MacMilanzi> Okay
| |
| 16:41 | <alkisg> Regarding gdm, I guess this file is to blame: /etc/pam.d/gdm-autologin
| |
| 16:41 | It's not including common-auth, so then pamltsp can't intervene and ssh to the server
| |
| 16:42 | Which means you'll need nfs for gdm, until this issue is fixed
| |
| 16:42 | Let's see lightdm now
| |
| 16:43 | <MacMilanzi> Okay, so i would have to use nfs, but nfs-kernel server is installed.
| |
| 16:46 | AppleMuncy has joined IRC (AppleMuncy!~AppleMunc@c-68-54-121-77.hsd1.in.comcast.net) | |
| 16:50 | <alkisg> MacMilanzi: I think newer versions of lightdm and gdm broke the autologin ability of ltsp + sshfs
| |
| 16:50 | I haven't noticed because we're using nfs here (with autologin)
| |
| 16:50 | Anyway, wanna switch to nfs home?
| |
| 16:51 | <MacMilanzi> Oh okay, so how does the nfs work?
| |
| 16:51 | <alkisg> https://ltsp.org/man/ltsp-nfs/#examples
| |
| 16:51 | <MacMilanzi> Yes, lets switch.
| |
| 16:51 | <alkisg> NFS is less secure. It makes your /home available on the local network without authentication
| |
| 16:51 | OK
| |
| 16:54 | Is ltsp146 rebooting properly?
| |
| 16:55 | <MacMilanzi> yes
| |
| 16:55 | its coming up right now. not yet there though
| |
| 16:56 | will there be fixes though with the latest lightdm + ltsp? for autologin?
| |
| 16:56 | <alkisg> Probably, but much later...
| |
| 16:57 | <MacMilanzi> Okay.
| |
| 16:57 | <alkisg> Test if thongs work as expected now with nfs
| |
| 16:57 | s/thongs/things/
| |
| 16:57 | <MacMilanzi> Alright, let me check.
| |
| 16:58 | yes it is working as expected.
| |
| 16:59 | <alkisg> ok great
| |
| 16:59 | <MacMilanzi> my script on startup ist still not executing though.
| |
| 16:59 | <alkisg> Where did you put it?
| |
| 17:00 | <MacMilanzi> "/etc/xdg/autostart/"
| |
| 17:01 | <alkisg> MacMilanzi: you cannot put .sh files there, they need to be .desktop files
| |
| 17:01 | see the other files there; create a similar one, that calls your sh file in the Exec line
| |
| 17:01 | <MacMilanzi> Alright, thanks!
| |
| 17:01 | <alkisg> You can test it on the server, before running ltsp image
| |
| 17:01 | It should work on the server before it works on the clients
| |
| 17:01 | OK, cheers
| |
| 17:02 | <MacMilanzi> Ok, thanks for your help!
| |
| 17:02 | <alkisg> You're welcome
| |
| 17:02 | <MacMilanzi> I appreciate it. How do i diconnect now on the epoptes?
| |
| 17:03 | <alkisg> Click the disconnect button in the window
| |
| 17:03 | I don't see the connection dialog.... not a new one, the old one
| |
| 17:03 | Anyway I'm closing from my side
| |
| 17:04 | <MacMilanzi> Thanks!
