<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?

<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

14:33
<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
<alkisg>
At what point does it say access denied?
14:40gbaman 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...
