| 12:19 | <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"

| 15:05 | <ltsp_user44> 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:

| 15:28 | <alkisg> ltsp_user44: ok if you're still here, do this ^ to vnc to me; I'll leave in a few minutes though...

| 15:54 | <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!
