| 12:07 | <louiloui> morning all
| |
| 12:10 | I have a question regarding LTSP and multi-arch clients
| |
| 12:11 | so an environment with a single server, connected to clients that could be ARM or x86
| |
| 12:11 | how non-trivial is this to setup?

| |
| 14:10 | <alkisg> louiloui: see the first link above ^
| |
| 14:10 | It's i386 and armhf
| |
| 14:16 | <louiloui> alkisg thx, I got into this looking at pinet.org.uk
| |
| 14:18 | so the thing is I am not wanting to use an rPi
| |
| 14:18 | but just an ARM device
| |
| 14:18 | but I would also like to have an x86 client as well
| |
| 14:18 | <alkisg> louiloui: did you read the link I said?
| |
| 14:19 | It has i386 and armhf
| |
| 14:19 | <louiloui> yes I have read all three links
| |
| 14:19 | perhaps I am misunderstanding
| |
| 14:19 | <alkisg> (04:18:46 μμ) louiloui: but I would also like to have an x86 client as well ==> the link mentions that it supports that
| |
| 14:19 | It starts with an ltsp server with x86 clients, and then adds armhf support
| |
| 14:20 | For rpi, but you can adjust it to your board
| |
| 14:20 | Which board is that?
| |
| 14:20 | <louiloui> I am not using an rPi
| |
| 14:20 | PcDuino3
| |
| 14:21 | an atom quad core tablet with PXE support
| |
| 14:21 | and an i7 as the server
| |
| 14:21 | <alkisg> ...why do you want arm then?
| |
| 14:22 | <louiloui> to share login credentials and a home folder, and common sw (not the same image, I understand x86 and arm compiled programs will each need their own image)
| |
| 14:22 | it's just something fun I thought about
| |
| 14:23 | <alkisg> Which ARM device are you using?
| |
| 14:23 | <louiloui> pcduino 3
| |
| 14:23 | <alkisg> (04:21:09 μμ) louiloui: an atom quad core tablet with PXE support
| |
| 14:23 | atom is x86, isn't it?
| |
| 14:23 | Maybe it's not atom?\
| |
| 14:23 | <louiloui> that is another separate machine I wish to use as a client
| |
| 14:23 | I'm not sure that I am explaining this correctly
| |
| 14:23 | <alkisg> You have an i7 server
| |
| 14:24 | <louiloui> yes
| |
| 14:24 | <alkisg> And you want to have arm pcduino3 clients and an atom client
| |
| 14:24 | <louiloui> yes
| |
| 14:24 | <alkisg> Then, follow the page I said, and adjust the things that are about pi, to be about the pcduino3 client
| |
| 14:24 | <louiloui> are you talking about http://cascadia.debian.net/trenza/Documentation/raspberrypi-ltsp-howto/
| |
| 14:24 | <alkisg> I assume that you've already been able to install ubuntu in pcduino, right?
| |
| 14:24 | !raspberrypi
| |
| 14:24 | <ltsp> raspberrypi: (#1) Ubuntu/LTSP on Pi 2: https://help.ubuntu.com/community/UbuntuLTSP/RaspberryPi, or (#2) Debian/LTSP (with raspbian chroot) on Pi: http://cascadia.debian.net/trenza/Documentation/raspberrypi-ltsp-howto/, or (#3) unofficial Ubuntu/LTSP (with raspbian chroot) on Pi: http://pinet.org.uk/
| |
| 14:25 | <alkisg> I said the first link there
| |
| 14:25 | Which one is the first one?
| |
| 14:25 | <louiloui> https://help.ubuntu.com/community/UbuntuLTSP/RaspberryPi
| |
| 14:25 | <alkisg> Right, that one
| |
| 14:25 | It tells you how to support x86 and arm
| |
| 14:26 | but it speaks for pi instead of pcduino3
| |
| 14:26 | You'll need to adjust some steps
| |
| 14:26 | There's no tutorial for pcduino3, you need to modify the one for rpi.
| |
| 14:26 | <louiloui> ...
| |
| 14:28 | so follow https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp really then
| |
| 14:29 | which I had read before you posted any links, but right at the top
| |
| 14:30 | "Your clients need to be the same architecture as your server, so if they're i386, you need to install the i386 Ubuntu variant in the server as well."
| |
| 14:30 | which was why I asked
| |
| 14:31 | thank you for the help, it's probably just referring to the scope of the guide covering the i386, I am working backwards, the server exists, the arm is working, I have to build the i386 part
| |
| 14:32 | I now understand that I simply need to build an alternative image
| |
| 14:32 | dlkauf has joined IRC (dlkauf!4ada5522@gateway/web/freenode/ip.74.218.85.34) | |
| 14:33 | <dlkauf> Hi there guys. I asked this question the other day and I figured I would come back. I am having an error installing the LTSP via PNP on a server runnin 14.04.03 Ubuntu server
| |
| 14:34 | The error I am getting says Disconnect all NDB client services on stop yes/no
| |
| 14:35 | This seems to happen on the ltsp client install part of the setup. I cant seem to figure out whats causing it, this is a clean install of ubuntu and ltsp
| |
| 14:36 | <alkisg> louiloui: yes, if you already have arm working, then you need ltsp-build-client --arch i386
| |
| 14:36 | dlkauf: are you using the greek schools ppa?
| |
| 14:37 | <dlkauf> I believe so. ts.sch.gr
| |
| 14:37 | <alkisg> At what point are you seeing that error?
| |
| 14:38 | Ah wait, are you talking about a blue screen with a dialog that asks you a question
| |
| 14:38 | ?
| |
| 14:38 | <dlkauf> while it is installing all the packages. I believe it is happening when it is installing the ltsp-client step
| |
| 14:38 | <alkisg> That's a normal "debconf" question of the "nbd-client" package
| |
| 14:38 | You see similar questions in other packages too, e.g. oracle, msttcorefonts etc
| |
| 14:38 | <dlkauf> yes its asking me a question.
| |
| 14:38 | <alkisg> You can answer either yes or no, it doesn't matter
| |
| 14:38 | So just press enter
| |
| 14:39 | <dlkauf> Well I have tried that. I have done yes and no. But once it finishes the install and I button it all up when I try to start my thin client it says the connection was dennied from the server
| |
| 14:40 | <alkisg> The question is unrelated to the result you see
| |
| 14:40 | gbaman has left IRC (gbaman!~gbaman@host81-139-185-126.in-addr.btopenworld.com, Remote host closed the connection) | |
| 14:40 | <alkisg> At what point does it say access denied?
| |
| 14:40 | gbaman has joined IRC (gbaman!~gbaman@host81-139-185-126.in-addr.btopenworld.com) | |
| 14:41 | <dlkauf> ok well then that is good. After it finds the server and starts to get the image to boot the client it says access dennied.
| |
| 14:41 | I appolgize I am in the middle of installing the LTSP on the server again, as I thought it had something to do with the ndb client question.
| |
| 14:42 | I am just about done with that and when I finish I will turn on a client and get the exact message
| |
| 14:42 | <alkisg> You need to troubleshot it
| |
| 14:42 | !quiet-splash
| |
| 14:42 | <ltsp> quiet-splash: to disable the splash screen in Ubuntu, in order to see any boot error messages, run sudo gedit /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default and remove quiet splash plymouth:force-splash vt.handoff=7
| |
| 14:43 | <alkisg> It helps if you remove splash and take a screenshot with your phone
| |
| 14:44 | <dlkauf> it is happening even before the splash screen pops up it is still running the code when it errors out
| |
| 14:44 | <alkisg> Are you using ipappend 3? Is it there in pxelinux/cfg/default?
| |
| 14:44 | <dlkauf> yes the ipappend 3 I am following the pnp install to the letter. This is what I have used on the install in the past and it worked just fine.
| |
| 14:45 | <alkisg> Is ipappend in pxelinux.cfg?default?
| |
| 14:45 | grep -i ipappend /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
| |
| 14:45 | <dlkauf> I do not know. I am at that step of the install now
| |
| 14:46 | <alkisg> The command above answers if it's there or not, just execute it and tell us the result
| |
| 14:53 | <dlkauf> no such file or directory
| |
| 14:53 | hold on a sec I spelled something wong in it let me do it again
| |
| 14:54 | yep no such file or directory
| |
| 14:56 | <alkisg> ls /var/lib/tftpboot/ltsp
| |
| 14:56 | What is the output of that?
| |
| 14:57 | <dlkauf> it says is a directory
| |
| 14:58 | <alkisg> With no files inside it?
| |
| 14:58 | E.g. I have an i386 folder inside it
| |
| 14:59 | Do you know how to use pastebin.com?
| |
| 14:59 | If yes, put the output of this command in pastebin:
| |
| 14:59 | ls -lhaR /var/lib/tftpboot/ltsp
| |
| 14:59 | This will show us if all the necessary files are there
| |
| 15:00 | <dlkauf> I have not used pastebin but It says i386
| |
| 15:02 | * alkisg needs to go, but it's standard troubleshooting, someone else might be able to help you... | |
| 15:02 | alkisg is now known as work_alkisg | |
