| 10:33 | <eu^static-176-15> Hi there. I'm trying ltsp. I've installed the server, create a vmdk image, followed the doc, etc. I run a client which boots correctly with ipxe and load ltsp image. Then when trying to mount my vm image, mount fails with /dev/loop0 .. no such device. I'm in a debug shell right now. Somebody can help/direct me ?
| |
| 10:34 | <alkisg> eu^static-176-15: can you upload a screenshot of the error to imgur.com?
| |
| 10:35 | eu^static-176-15: also, which ltsp version?
| |
| 10:36 | dpkg -l | grep ltsp
| |
| 10:37 | <eu^static-176-15> ii ltsp 20.01-1~202001301202~ubuntu18.04.1 all Linux Terminal Server Projectii ltsp-binaries 19.11-1~201911110713~ubuntu18.04.1 all Linux Terminal Server Project binaries
| |
| 10:37 | on the server side.
| |
| 10:38 | os on client is debian 10, and I ust the ppa repo
| |
| 10:38 | <alkisg> ppa is fine, has 20.01 too
| |

| |
| 10:39 | <alkisg> eu^static-176-15: I believe that you didn't install ltsp in the vmdk image, as the installation page says
| |
| 10:39 | !install
| |
| 10:39 | <ltspbot> install: To install LTSP: https://ltsp.org/docs/installation/
| |
| 10:39 | <alkisg> This will give you the squashfs module in the initramfs, which is necessary
| |
| 10:39 | <eu^static-176-15> Well, I did it this morning. I gonna double check.
| |
| 10:39 | <alkisg> *inside* the vmdk, you're supposed to install ltsp, and this is supposed to run update-initramfs, and put squashfs in the initramfs
| |
| 10:39 | <eu^static-176-15> from the debug shell, I've checked the module was availble.. modprobe squashfs is fine for example
| |
| 10:40 | oh ok. May be the updateinitramfs was not done.
| |
| 10:41 | I've juste done apt install ltsp epoptes-client..
| |
| 10:41 | Should I launch an update-initramfs after that ?
| |
| 10:41 | checking..
| |
| 10:46 | This is on the client image:root@debian:/etc/apt# apt install epoptes-clientLecture des listes de paquets... FaitConstruction de l'arbre des dépendances Lecture des informations d'état... Faitepoptes-client est déjà la version la plus récente (20.01-1~ubuntu18.04.1).0 mis à jour, 0 nouvellement installés, 0 à enlever et 0 non mis à
| |
| 10:46 | jour.root@debian:/etc/apt# dpkg -l | grep ltspii ltsp 20.01-1~202001301202~ubuntu18.04.1 all Linux Terminal Server Project
| |
| 10:46 | ok, it's in french but it says the packages are installed..
| |
| 10:46 | Should I run an update-initramfs ?
| |
| 10:48 | <alkisg> (12:39:53 PM) eu^static-176-15: from the debug shell, I've checked the module was availble.. modprobe squashfs is fine for example
| |
| 10:48 | <eu^static-176-15> I can see the initrd was rebuild this morning when I installed the packages.
| |
| 10:48 | <alkisg> grep squashfs /proc/filesystems
| |
| 10:48 | Is it there in the initramfs shell?
| |
| 10:50 | <eu^static-176-15> no :-(
| |
| 10:50 | <alkisg> Maybe you installed ltsp in the vmdk, AFTER you had previously ran ltsp image?
| |
| 10:50 | Anyway, run update-initramfs -u and ltsp image outside
| |
| 10:51 | update-initramfs -u inside
| |
| 10:58 | <eu^static-176-15> yeah, understood. Doing it again..
| |
| 11:00 | Well. I think I missed a step in my special conf.. Basically I used my image rom yeserday on which I didn't install the ltsp packages.. I think it gonna work in a few minutes.. I tell you. thanks anyway.
| |
| 11:21 | <alkisg> np
| |
| 11:33 | <eu^static-176-15> ok, it boots, thanks a lot.
| |
| 11:38 | My client had a user preconfigured: it has disappeared or I can't log with it. And the user I've created on the ltsp server is shown but I can't log with it.. Dunno if there is a problem with the password or the home ..

| 11:42 | <alkisg> eu^static-176-15: ltsp initrd
| |
| 11:43 | Also, make sure that sshfs was installed in the vmdk
| |
| 11:43 | (it gets automatically installed when you install ltsp)
| |
| 11:43 | <eu^static-176-15> Is there a way to keep the user I've install on the vmdk ?
| |
| 11:44 | <alkisg> eu^static-176-15: yes, the pw_merge ltsp.conf directives, see man ltsp.conf
| |
| 11:44 | !ltsp.conf
| |
| 11:44 | <ltspbot> ltsp.conf: Configuration file for LTSP: https://ltsp.org/man/ltsp.conf/
| |
| 11:45 | <alkisg> eu^static-176-15: but note that if you're using sshfs, he would need to be able to ssh to the server
| |
| 11:45 | If you're using NFS home, then there's no need for that user to exist on the server
| |
| 11:45 | (or local home)
| |
| 12:01 | statler has left IRC (statler!~Georg@gwrz.lohn24.de, Ping timeout: 240 seconds) | |
| 12:02 | statler has joined IRC (statler!~Georg@gwrz.lohn24.de) | |
| 12:03 | <eu^static-176-15> ok, I guess I have to add users & groups I want to keep in the [clients] section of ltsp.conf, in PWMERGE_D[GU]R variables. Then ltsp initrd ?
| |
| 12:04 | <alkisg> eu^static-176-15: yes, but note what I said above about sshfs
| |
| 12:05 | <eu^static-176-15> my user has a local home which should be in the squashfs .. I understand all the modifications he will do on his home will be lost..
| |
| 12:05 | So.. Should he be created on the server too ?
| |
| 12:06 | <alkisg> eu^static-176-15: you should use OMIT_IMAGE_EXCLUDES to keep home from the .vmdk
| |
| 12:06 | As normally it comes from the server
| |
| 12:07 | Or, you can create it dynamically with a POST_INIT parameter
| |
| 12:07 | Yeah that's probably more verbose/logical
| |
| 12:07 | And you'll need to allow passwordless logins for these users, as they don't exist on the server
| |
| 12:07 | Again from ltsp.conf
| |
| 12:10 | <eu^static-176-15> Well, I prefere to keep the home so far, as I've provisioned stuffs on it.
| |
| 12:10 | OMIT_IMAGES_EXCLUDES has to be set in the server section ?
| |
| 12:10 | I guess
| |
| 12:11 | <alkisg> Yes
| |
| 12:15 | <eu^static-176-15> PASSWORDS_x ? PASSWORDS_0 .. PASSWORDS_n ? I see in the sample that it's based on the client's hostname ? Can it be done for all the clients ?
| |
| 12:16 | PASSWORDS="myuser/" ?
| |
| 12:16 | <alkisg> PASSWORDS_MYUSER="myuser/"
| |
| 12:16 | It needs the dash there, _
| |
| 12:18 | <eu^static-176-15> I guess I can put anything behind _ so.
| |
| 12:23 | <alkisg> Right
| |

| 12:59 | <eu^static-176-15> Still can not see my image user. I've added in the [clients] section PWMERGE_DGR="admindebian"PWMERGE_DUR="admindebian"PASSWORDS_ADMINDEBIAN="admindebian/aBase64Pass"
| |
| 13:00 | I can log with the user from the ltsp server.. But I don't see the admindebian user in lightdm, and if I try to log with it it does not work
| |
| 13:01 | I can't see it either with getent passwd once I'm logged onto the client. I'm wondering if the uid/gid don't collide by the way.

| 13:02 | <eu^static-176-15> the whole /home is mount on the client ? Is the a way to mount on a n other folder ?
| |
| 13:03 | no. It's a per user mount..
| |
| 13:05 | argh.. the path in the omit option are relative... I put /home.
