<John53>
Hello everyone, you have brought me a very valuable help and I finally managed to get a functional classroom ... Nevertheless, I still have a little worry and I can not know where can come the problem: On client PCs, I can not access the internet. It does not even show me the network card, while the boot is done well. However, I have internet
12:19
access on the server.
12:21
Then when starting client PCs, the session manager does not display a user list, students are forced to enter their session name ... Is there a way to change it?
12:22
I specify that I am in chrootless mode and that I perform the installation of my server with a single network card (no dual NIC)
12:30
On client PCs, the network card says: wired unmanaged
12:44
@Alkisg: I think this comes from "netplan"

Hello everyone, someone speaks Spanish?
15:06
<alkisg>
I haven't seen anyone here; you can use google translate though
15:09
<ltsp_user44>
Ok, I have a question about chroot mode in the new version of ltsp
15:10
no pude hacer que funcione
15:10
I couldn't make it work
15:11
<alkisg>
what was the issue?
15:17
<ltsp_user44>
Basically clients do not start in chroot mode, modify ltsp.ipxe by adding parameters: cmdline_method root = / dev / nfs nfsroot = $ {srv}: / srv / ltsp / $ {img} boot = nfs
15:19
we have an infrastructure of 200 ltsp users in version 5 in chroot mode, we want to upgrade to the version but we cannot maintain that characteristic
15:22
<alkisg>
You don't have to edit ltsp.ipxe
15:22
It already supports chroots
15:25
I'll be available for remote support in 10 minutes if you want
15:25
Like this:
15:25
!vnc-edide
15:25
<ltsp>
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
15:28
<alkisg>
ltsp_user44: ok if you're still here, do this ^ to vnc to me; I'll leave in a few minutes though...

<ltsp_user44>
hello I came back
15:59
<Ark74>
ltsp_user44, are you using ltsp 19+?
15:59
<ltsp_user44>
yes
16:00
ltsp 19.09-1
16:01
<Ark74>
parece que perdiste a alkisg para soporte remoto
16:01
<ltsp_user44>
201909270719-ubuntu18
16:01
Hola
16:01
<Ark74>
hey
16:03
contactalo, creo que él es el más indicado para una tarea de este tipo
16:03
(si es que está disponible, claro)
16:03
<ltsp_user44>
si aca espero
16:04
<Ark74>
puedo preguntar que tipo de clientes usas?
16:04
<ltsp_user44>
eres usuario de ltsp?
16:04
<Ark74>
estoy retomandolo después de un largo rato, usamos ltsp 5.3 en ese entonces
16:05
<ltsp_user44>
claro nosotros tambien
16:05
<Ark74>
y precisamente la idea es retomar ahora con ltsp 19+
16:05
<ltsp_user44>
tenemos aproximadamente 200 usuarios con ubuntu 16
16:05
ubuntu mate 16
16:05
si nosotros ttambien
16:07
<Ark74>
leiste este mensaje? <ltsp> 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
16:08
<ltsp_user44>
si si
16:09
<Ark74>
Ok
16:10
<ltsp_user44>
nostros tenemos todos clientes livianos
16:10
somos una entidad gubernamental
16:11
<Ark74>
ok, entonces todo va sobre red
16:12
si no es indiscreción, que tipo de cliente ligero usan?
16:13
nuestra implementación era mas modesta, un aula de medios para una escuela, no mas de 15 clientes
16:13
<ltsp_user44>
usamos dell optiplex 180
16:14
servidores dell
16:14
en ambiente virtualizado
16:14
vmware esxi 6.7
16:15
lo que nos esta ocurriendo es que los procesos se estan ejecutando localmente ne las terminales
16:15
no asi en el servidor
16:15
<Ark74>
usaste localapps?
16:16
<ltsp_user44>
en el ambiente de produccion con version 5 no lo usamos debido a la poca memoria de las clientes
16:17
la idea es usar en version nueva
16:20
<Ark74>
como? entonces no están arrancando correctamente y pasan a iniciar desde el HDD?
16:31* alkisg is back too, but doesn't speak spanish :)
16:32
<alkisg>
ltsp_user44: are you here?
16:37
ltsp_user44: I tried to read what you said using google translate; I think you're looking for thin client mode, where the applications run on the server
16:38
In LTSP19, this is only supported by xfreerdp, for example: https://github.com/ltsp/ltsp/issues/39#issuecomment-539150708
16:43
If you come here, tell us your client specifications, e.g. Pentium 4 with 1 GB RAM?
16:43
<ltsp_user44>
hello
16:45
yes intel atom with 1gb
16:45
<alkisg>
OK then these run better as fat clients
16:45
You don't need thin client mode
16:47
<ltsp_user44>
ok, but is it possible that the processes run on the server not on the client?
16:48
<alkisg>
In LTSP19, this is only supported by xfreerdp, for example: https://github.com/ltsp/ltsp/issues/39#issuecomment-539150708
16:48
<ltsp_user44>
because they have recently acquired new servers with 250 gb of ram to function as an ltsp server
16:48
oka
16:49
<alkisg>
This was a very bad idea :)
16:49
They should have bought clients instead
16:52
<ltsp_user44>
jaja yes I agree
16:54
<alkisg>
Remote xorg is getting deprecated, people move to wayland etc
16:54
Thin clients aren't "in" anymore
16:55
<ltsp_user44>
ok
16:56
we have a boss to convince
16:57
we have another query
16:57
<Ark74>
alkisg, So, are thin clients dying with LTSP5?
16:59
<alkisg>
Ark74: yes
16:59
Remote xorg is dying upstream
16:59
x2go won't work on wayland
16:59
So I think rdp and pipewire will live
17:04
<Ark74>
... interesting
17:04
that's a game changer
17:05
<alkisg>
So soon thin clients will probably mean "netbooted clients with a remote desktop program"
17:06
The "xorg can run over the network" idea was deprecated like 10 years ago; it was on life support...
17:06
<Ark74>
hehehe
17:07
well, time to get 2019 sink in I guess
17:08
<alkisg>
xfreerdp support, kiosk mode, guest sessions etc can be implemented in ltsp19 with a few lines in ltsp.conf
17:08
And I guess someone could also easily implement thin clients with X -query
17:09
But I won't include code for localapps, remoteapps, ltspfs etc; xfreerdp and x2go already support remote file systems, printing, local devices etc
17:10
<Ark74>
have a lot of reading a testing to do now that I'm back to ltsp 19+
17:10
a lot happened since 5.3
17:11
<alkisg>
Ark74: the best thing to do is to follow the installation guide to the letter, so that you get things up and running in 10 minutes after os installation,
17:11
and *then* start customizing to your needs
17:12
<Ark74>
o/
17:13
what popular client will be a good one?
17:14
I saw that RPi4 had some nice upgrades, but maybe it is still under powered
17:14
<alkisg>
!cheap-client
17:14
<ltsp>
cheap-client: https://www.gearbest.com/tv-box-c_11262/?attr=2081-1279
17:15
<alkisg>
Rpi4 is indeed underpowered, but it's a LOT better than rpi2/3
17:15
It's similar to atoms
17:15
*first generation atoms, not recent ones
17:16
But in general if you want desktop systems, buy desktop systems. LTSP helps you in maintaining one installation for any number of diskless clients; it doesn't lighten the hardwrae needs
17:16
<Ark74>
the nice thing about RPis is the "set sd and ready 2 go" workflow
17:17
<alkisg>
That's actually the very sad part
17:17
As they don't support netbooting properly
17:17
So you have to update things in the SD card on each kernel update
17:17
While all the normal things like PCs, support netbooting from their BIOS/UEFI
17:17
And don't need local media updates
17:18
In 5-10 years, I think rpi6 or 7 will finally get netbooting right, and have a semi decent cpu, to be used as desktop
17:18
But for now... I'd stay away from them :)
17:19
(typing these from an rpi; but only used for remote desktop, not as desktop :))
17:19
<Ark74>
Ok xDD
17:19
is gPXE still around?
17:19
<alkisg>
It's now called ipxe
17:19
<Ark74>
ohh!
17:19
<alkisg>
LTSP19 uses ipxe instead of syslinux
17:20
To be able to support uefi, show menus etc
17:20
<Ark74>
I have a lot to catch up then xD
17:21
thanks for the comments and suggestions!
