local-boot: If you want LTSP fat clients on a low-speed network, you can put i386.img on e.g. C:\Boot\LTSP\i386.img and use this command line in pxelinux.cfg: APPEND ro initrd=ltsp/i386/initrd.img init=/sbin/init-ltsp root=/dev/sda1 rootflags=ro loop=/Boot/LTSP/i386.img; IPAPPEND 3

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 ?
eu^static-176-15: can you upload a screenshot of the error to imgur.com?
eu^static-176-15: also, which ltsp version?
dpkg -l | grep ltsp
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
on the server side.
os on client is debian 10, and I ust the ppa repo
ppa is fine, has 20.01 too
eu^static-176-15: I believe that you didn't install ltsp in the vmdk image, as the installation page says
install: To install LTSP: https://ltsp.org/docs/installation/
This will give you the squashfs module in the initramfs, which is necessary
Well, I did it this morning. I gonna double check.
*inside* the vmdk, you're supposed to install ltsp, and this is supposed to run update-initramfs, and put squashfs in the initramfs
from the debug shell, I've checked the module was availble.. modprobe squashfs is fine for example
oh ok. May be the updateinitramfs was not done.
I've juste done apt install ltsp epoptes-client..
Should I launch an update-initramfs after that ?
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
jour.root@debian:/etc/apt# dpkg -l | grep ltspii ltsp 20.01-1~202001301202~ubuntu18.04.1 all Linux Terminal Server Project
ok, it's in french but it says the packages are installed..
Should I run an update-initramfs ?
(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
I can see the initrd was rebuild this morning when I installed the packages.
grep squashfs /proc/filesystems
Is it there in the initramfs shell?
Maybe you installed ltsp in the vmdk, AFTER you had previously ran ltsp image?
Anyway, run update-initramfs -u and ltsp image outside
update-initramfs -u inside
yeah, understood. Doing it again..
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.
ok, it boots, thanks a lot.
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 ..

eu^static-176-15: ltsp initrd
Also, make sure that sshfs was installed in the vmdk
(it gets automatically installed when you install ltsp)
Is there a way to keep the user I've install on the vmdk ?
eu^static-176-15: yes, the pw_merge ltsp.conf directives, see man ltsp.conf
ltsp.conf: Configuration file for LTSP: https://ltsp.org/man/ltsp.conf/
eu^static-176-15: but note that if you're using sshfs, he would need to be able to ssh to the server
If you're using NFS home, then there's no need for that user to exist on the server
(or local home)

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 ?
eu^static-176-15: yes, but note what I said above about sshfs
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..
So.. Should he be created on the server too ?
eu^static-176-15: you should use OMIT_IMAGE_EXCLUDES to keep home from the .vmdk
As normally it comes from the server
Or, you can create it dynamically with a POST_INIT parameter
Yeah that's probably more verbose/logical
And you'll need to allow passwordless logins for these users, as they don't exist on the server
Again from ltsp.conf
Well, I prefere to keep the home so far, as I've provisioned stuffs on it.
OMIT_IMAGES_EXCLUDES has to be set in the server section ?
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 ?
It needs the dash there, _
I guess I can put anything behind _ so.

Still can not see my image user. I've added in the [clients] section PWMERGE_DGR="admindebian"PWMERGE_DUR="admindebian"PASSWORDS_ADMINDEBIAN="admindebian/aBase64Pass"
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
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.

the whole /home is mount on the client ? Is the a way to mount on a n other folder ?
no. It's a per user mount..
argh.. the path in the omit option are relative... I put /home.
