Hi. I have installed LTSP on a normal desktop (Intel Core2 / 4GB ram) running 64bit Kubuntu 16.04.3LTS. And I want to connect to it using a RaspberryPi-3.
07:48
I followed the steps as in : http://wiki.ltsp.org/wiki/Ltsp-manager/Installation
07:49
And, post this I ran the steps as in : https://help.ubuntu.com/community/UbuntuLTSP/RaspberryPi
07:50
I want to install only the thin client.
07:50
When I run the step : ltsp-build-client --arch armhf --config /etc/ltsp/ltsp-build-client-raspi2.conf
07:53
I get an error message :
07:54

There's a bug in ltsp-update-sshkeys, you need to apply this patch on the server to fix it: https://git.launchpad.net/ltsp/commit/?id=b1030c40f40930928f2f114f96419edbeddb5e17

Thanks for the moment Alkis. I am now rerunning the ltsp-build-client after lstsp-update-sshkeys patch. Will let you know how it all goes.

Hi Alkis
14:04
I have done all the steps related to the thin client for RaspberryPi-3 (which are basically the RaspberryPi-2 steps itself) in the RaspberryPi help page (https://help.ubuntu.com/community/UbuntuLTSP/RaspberryPi)
14:04
I have made the SD image also as listed in it.
14:05
Now when I boot up my Raspberry, I get an error : "Gave up waiting for root device. Common problems:" ....
14:06
And then : "ALERT! /dev/nbd0 does not exist. Dropping to a shell!"
14:11
And a little before that, I had also got an error message :
14:12
Begin: Mounting root file system ... Begin: Running /scripts/local-top ... Begin: Setting up nbd-client ... [ <some number> nbd: registered device at major 43
14:13
Negotiation: ..Error: Read failed: End of file
14:13
Exiting.
14:13
done.
14:26
Could anyone please help me understand what is going wrong ?

Hi
15:41
<alkisg>
!nbd-client
15:41
<ltsp>
nbd-client: To try mounting the NBD image from the client initramfs: nbd-client 192.168.67.1 -N /opt/ltsp/i386 /dev/nbd0
15:41
<alkisg>
jp_: try that ^ while putting the correct server ip, from the raspberry initramfs shell
15:42
<jp_>
ok, let me try that ...
15:43
i guess, instead of /opt/ltsp/i386 I will need to use /opt/ltsp/armhf
15:43
Right ?
15:43
<alkisg>
Right
15:44
<jp_>
Btw, I do not find nbd-server.allow file either in "/etc/ltsp/nbd-server.allow"
15:44
Could that also be an issue ?
15:45
Or, is it that I need to create this file myself ?
15:47
<alkisg>
No, that file should not exist
15:49
<jp_>
After running nbd-client <server-ip> -N /opt/ltsp/armhf /dev/nbd0 I get an error :
15:50
Negotiation: ..Error: Read failed: End of file
15:50
Exiting.
15:52
<alkisg>
And does it work with your i386 or amd64 configuration?
15:52
i.e. -N /opt/ltsp/amd64
15:53
<jp_>
I have only 2 directories under /opt/ltsp : "armhf", and, "images"
15:54
<alkisg>
And what's inside images?
15:55markit has joined IRC (markit!~marco@88-149-177-66.v4.ngi.it)
15:55
<jp_>
"amd64.img", and, "armhf.img"
15:55nehemiah has joined IRC (nehemiah!~nehemiah@saphar.net)
15:55
<alkisg>
ok, try nbd-client -N /opt/ltsp/amd64
15:57
<jp_>
Still the same error
15:58
<alkisg>
And yet an amd64 client can boot?
15:58
<nehemiah>
We're coming to a point where everything seems to be working really well. I wanted to thank everybody for there advise and input! We are getting into the stage of making an automated installation the can easily replicate the setup.
15:59
<jp_>
@alkisg : How do I test that ?
15:59
<nehemiah>
There's just a couple more questions. Can I, for thin clients, downgrade the amount of colors displayed to make up a little for the network latency? Like you can with x2go?
15:59
<alkisg>
jp_: have you booted any clients with this ltsp setup?
16:00
<jp_>
No.
16:00
I am directly trying through my RaspberryPi-3
16:01
<alkisg>
OK, this means that there may be more issues to be addressed server-side than just nbd-server
16:01
Unfortunately I don't have much time currently, I'll be available again a few hours, or tomorrow...
16:01
!lts.conf
16:01
<ltsp>
lts.conf: (#1) http://manpages.ubuntu.com/lts.conf, or (#2) lts.conf manpage is available in the ltsp-docs package
16:01
<alkisg>
nehemiah: check X_COLOR_DEPTH there, you can set it to 16
16:03
<jp_>
Is there any way to check if my Raspberry client is able to connect to my Kubunto server and access /opt/ltsp/*
16:22
<markit>
jp_: ehi, I use kubuntu too :) (not with raspberry though... I'm surprised it can work with it... any special fine tuning to reduce the I/O?)
16:27
<jp_>
markit: I have still not been able to get it working even for once.
16:32
I have a desktop (Intel Core2 ; 4GB ram, running 64bit Kubuntu 16.04.3LTS) with a single NIC. I have my LTSP Server installed on this. And, I am trying to get a RaspberryPi-3 (want to use it as a dumb terminal, like in the earlier days, but with a running GUI).
16:35
So, just want to be able to work on my Desktop through the RaspberryPi-3
16:37
Is there any way I can test (maybe from within initramfs) that there is no access issue from RPi to the LTSP Server ? Something similar to a ping / ssh ?
16:39
Through a normal Rasbian SD on my RPi, I am able to ssh to my Kubuntu without any issue, though.
