| 17:41 | <aurele98> hi everyone!
| |
| 17:44 | <alkisg> Hello aurele98
| |
| 17:45 | <aurele98> Do you guys have any clue why, when i'm trying to do a chroot from my powerPC, i got an error saying that i miss the "linux-image-powerpc" package ?
| |
| 17:47 | i searched and found linux-image-powerpc-smp but even with all packages updated and source changes it didnt worked so well
| |
| 17:47 | tbh i got the ambition to
| |
| 17:48 | sorry
| |
| 17:49 | to be honest my goal is to use the PPC as a thin client and the server would be a classic x64 architecture but in order to that i must do the chroot on the ppc first (if i'm reading well)

| 18:14 | <vagrantc> aurele98: good luck, not really well tested process doing PPC on x86

| 18:23 | <aurele98> yup, saw that :/
| |
| 18:34 | adrianor1 is now known as adrianorg | |
| 18:43 | <bennabiy> alkisg: any reason why epoptes would all of a sudden stop working?
| |
| 18:44 | I guess for another time
| |
| 18:44 | * bennabiy waves | |
| 18:44 | <aurele98> lel
| |
| 18:51 | <alkisg> bennabiy: no reason, no
| |
| 18:53 | aurele98: can you install some linux directly on the ppc?
| |
| 18:53 | If yes, then just install ltsp-client in it, and transfer the result to the server
| |
| 18:53 | No need to chroot then...
| |
| 19:00 | lucascastro has left IRC (lucascastro!~lucas@201.182.221.14, Ping timeout: 240 seconds) | |
| 19:03 | <aurele98> yes of course, forgot to say that i'm on lubuntu ppc
| |
| 19:04 | that's the whole problem
| |
| 19:04 | to do that i need the now famous "linux-image-powerpc"
| |
| 19:05 | <vagrantc> any linux-image will do, as long as it runs on the hardware you want to support
| |
| 19:05 | you don't need to install linux-image-powerpc specifically
| |
| 19:06 | if you insist on using a chroot, you can specify which linux-image package to use with --kernel-package, if i remember correctly
| |
| 19:06 | <aurele98> well isnt ltsp-build-client isnt a form of chroot ?
| |
| 19:07 | i thinki'm tired as hell guys
| |
| 19:07 | yes i am
| |
| 19:11 | i'll try something and inform you of what happened
| |
| 19:21 | <vagrantc> aurele98: you could do an ltsp-pnp method:
| |
| 19:21 | !ltsp-pnp | echo aurele98
| |
| 19:21 | <ltsp`> aurele98 ltsp-pnp: ltsp-pnp is the recommented method to install and maintain LTSP for "usual" setups. Since it doesn't involve chroots, it requires little to no command line to maintain it. It automatically supports both thin and fat ltsp clients. https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
| |
| 19:21 | <alkisg> aurele98: I don't understand, if you're in lubuntu ppc you already have a kernel
| |
| 19:21 | You don't need a new one...
| |
| 19:22 | Does ltsp-client force you to install something that you don't already have installed?
| |
| 19:22 | <aurele98> no
| |
| 19:22 | <vagrantc> aurele98: in general, we're discouraging ltsp-build-client and recommending ltsp-pnp
| |
| 19:22 | <aurele98> and that's weird
| |
| 19:22 | <alkisg> What's the output of `uname -a; ls /boot` in your ppcclient?
| |
| 19:22 | <aurele98> ok
| |
| 19:23 | sry i'm trying pnp rn brb
| |
| 19:24 | <alkisg> ltsp-pnp is suitable when you want the ppc to be the server
| |
| 19:24 | But you want an amd64 server
| |
| 19:24 | <aurele98> u got it
| |
| 19:24 | <alkisg> So in your case you just need to install ltsp-client in the ppc client, and transfer the result
| |
| 19:24 | <vagrantc> you can build the image on the PPC hardware, and copy the resulting image over to the server
| |
| 19:25 | <aurele98> yeah but it keeps crashing to that kernel thing
| |
| 19:25 | i dont get it
| |
| 19:25 | <vagrantc> what keeps crashing?
| |
| 19:25 | <alkisg> Paste specific commands and their whole output
| |
| 19:25 | <aurele98> i got linux image powerpc snp
| |
| 19:25 | <alkisg> Not just "it crashes", that doesn't help
| |
| 19:26 | !paste

| |
| 19:26 | <aurele98> ok
| |
| 19:27 | <alkisg> vagrantc: recent nbd bug, affecting the bpo kernels in stretch, and expected solution: https://github.com/NetworkBlockDevice/nbd/issues/57
| |
| 19:27 | (and also the stock kernels in 16.04)
| |
| 19:27 | <aurele98> oh i forgot i'm french so if there's some french tell me which sentence
| |
| 19:28 | <alkisg> Use "export LANG=C.UTF-8" before
| |
| 19:28 | Then the messages will be in English
| |
| 19:28 | <aurele98> k
| |
| 19:29 | thx a lot guys means really a lot
| |
| 19:30 | i'm saying that now cause u know, ppcs are slow
| |
| 19:30 | <vagrantc> aurele98: could you paste the command you're running while we wait?

| |
| 19:33 | <alkisg> Haha
| |
| 19:33 | I think we both were telling you: "don't use ltsp-build-client"
| |
| 19:34 | * alkisg gives up :) | |
| 19:35 | <aurele98> fuck me
| |
| 19:36 | aurele98butfaste has joined IRC (aurele98butfaste!4ec0c126@gateway/web/freenode/ip.78.192.193.38) | |
| 19:36 | <aurele98butfaste> ok
| |
| 19:37 | now i cant miss a message
| |
| 19:37 | <vagrantc> you just need to install the "ltsp-client" package on the PPC machine, and run "ltsp-update-image --cleanup /"
| |
| 19:37 | do not use ltsp-build-client
| |
| 19:37 | <aurele98> ok
| |
| 19:37 | fuck
| |
| 19:37 | <alkisg> !language
| |
| 19:37 | <ltsp`> Error: "language" is not a valid command.
| |
| 19:37 | <vagrantc> then, you can copy the /opt/ltsp/images/*.img to the server
| |
| 19:37 | that's the short of it... no idea if it will work. :)
| |
| 19:38 | <aurele98> i heard this idea before
| |
| 19:38 | <alkisg> It'll need an ssh keys update
| |
| 19:38 | <aurele98> but why did i ran that stupid command
| |
| 19:38 | <vagrantc> didn't we create a way to do that at runtime?
| |
| 19:38 | aurele98: ctrl-c should get you out of it
| |
| 19:38 | <aurele98> ofc i know why cause it worked for a guy
| |
| 19:39 | boy i feel like i'm the dumbest guy alive
| |
| 19:40 | <alkisg> vagrantc: not really, except for INIT_COMMAND_xx="ssh-keyscan server > /etc/ssh/known_hosts"...
| |
| 19:40 | Ah, and some directive to completely ignore them
| |
| 19:40 | LDM_OPTIONS=-o stricthostkeycheck etc
| |
| 19:43 | <aurele98> should i be concerned if it skips etherboot images / PXE configuration ?
| |
| 19:46 | <alkisg> no
| |
| 19:47 | <aurele98> ok thanks

| |
| 19:48 | <vagrantc> alkisg: we could append a cpio.gz with the initramfs that includes some extra stuff
| |
| 19:49 | aurele98butfaste: try /nick NAME
| |
| 19:49 | <aurele98butfaste> thanks, forgort all of my IRC exp
| |
| 19:50 | aurele98butfaste is now known as aurele98 | |
| 19:50 | <alkisg> vagrantc: i have an example implementation of booting ltsp with just that cpio.gz :)
| |
| 19:50 | No custom initrd at all...
| |
| 19:50 | <vagrantc> alkisg: how do you deliver the cpio.gz ?
| |
| 19:53 | <alkisg> 2 pxelinux lines
| |
| 19:57 | <vagrantc> that's pxelinux-specific
| |
| 19:57 | obviously...
| |
| 19:58 | i've been experimenting a bit with appending a cpio.gz to the initramfs ... so the only custom thing is cat initrd.img cpio.gz > initrd-with-extra-fun.img
| |
| 19:59 | that works with any standard debian kernel for the last 5 years or so
| |
| 20:00 | then any bootloader that supports initramfs supports that method
| |
| 20:00 | but yes, i'm getting tempted by one of those two approaches
