Hi Guys, has anyone managed to get efi bios working with LTSP clients
08:03
I'm not getting past the "initialising devices" part in the network boot screen, it just boot loops over and over again. I'm using a mikrotik to point the client to the PXE boot file /ltsp/amd64/ipxe.efi
08:03
it's under the tftp root directory
08:25
<cyberorg>
pxeguy, i've tested this https://github.com/openSUSE/kiwi/wiki/Setup-PXE-boot-with-EFI-Using-GRUB2
08:25
works on ubuntu also, adapt it as per your configuration
08:26
<pxeguy>
Thanks man, I will use that. I was worried that it wouldn't work with ubuntu, thanks for confirming that.

<al-geo>
hello people. Im little confused, i did setup kiwi-ltsp server and connect 2-3 clients. and all of them are just logged in server with ssh or rdesktop? than what is the meaning of i386.img? on clients lsb_release -a shows x86_64. i even dont know what to ask: can i change to login on client? (clients are diskless) can client have own IP? own arch? i find run apps localy option but if arch is different its useless for me. P.S. sorry for
08:35
<cyberorg>
al-geo, http://wiki.ltsp.org/wiki/Concepts thinclient mode everything runs on server after login, i386.img is used only to boot the client
08:36
fatclient mode everything runs on the client, so whatever is installed in i386.img or x86_64.img is run on the client, arch will show the image it was booting from
08:37
https://sourceforge.net/p/kiwi-ltsp/wiki/Customizing%20Image/ explains fatclient bit more
08:38
<pxeguy>
Hi Cyberorg, I'm using a method where by the storage is on the server and the client does all the work i.e the server just provides the image but the client actually does the work
08:42
<cyberorg>
pxeguy, on ubuntu, the difference was tftp path /var/lib/tftpboot and grub-mkstandalone -d /usr/lib/grub/x86_64-efi/ -O x86_64-efi --fonts="unicode" -o bootx64.efi boot/grub/grub.cfg
08:42
rest everything as per kiwi's guide, other thing is this does not work if dnsmasq is run in proxy mode
08:43
<pxeguy>
do I need to use dnsmasq for this to work, because with pxelinux.0 it worked just fine on a legacy bios
08:46
<cyberorg>
pxeguy, this is what working dnsmasq.d/ltsp.conf looks like http://paste.opensuse.org/58123039
08:47
<pxeguy>
so essentially, dnsmasq doesn't replace dhcp right?
08:47
and I can continue using dhcp on my mikrotik?
08:48
<cyberorg>
pxeguy, it replaces dhcp
08:48
xinetd and named as well
08:48
<pxeguy>
yes, so that is my problem at the moment. I need to use the mikrotik
08:48
to provide the boot file name etc
08:48
and dhcp
08:49
<cyberorg>
then try providing bootx64.efi instead of pxelinux
08:50
<pxeguy>
Have tried that aswell, I don't think I did it correctly though
08:50
It just skipped everything
08:50
and didn't even go into that booting environment
08:50
or the network boot screen
09:05
<alkisg>
pxeguy: if you are able to switch your clients to legacy (csm) mode, it's by far easier than configuring ltsp to work with uefi :)
09:06
So do research that route, before continuing...
09:06
<pxeguy>
yes it works fully with legacy boot and pxelinux.0
09:06
well not really.
09:06
It worked with an older thin client
09:07
<alkisg>
I mean with the new clients, to configure them so that they don't use uefi but legacy csm mode
09:07
<pxeguy>
but when I used this newer model all in one client, it loads everything but when it gets to where it's supposed to display the splash screen
09:07
<alkisg>
Usually there's an option for that in their firmware
09:07
<pxeguy>
but the display flashes green, blue, red...as if it's not able to display it
09:07
yes I'm configured that in the bios
09:07
and it loads fine
09:08
<alkisg>
If you get it to load the kernel+initrd, then you're done
09:08
<pxeguy>
yes it does
09:08
<alkisg>
The next parts are not related to bios/uefi
09:08
<pxeguy>
for sure
09:08
<alkisg>
I.e. even if you implement uefi booting, you'll still see the display issue
09:08
<pxeguy>
I see
09:08
then it is a problem with the actual unit?
09:08
weird
09:09
it's like it doesn't want to pickup the display
09:09
<alkisg>
So, try "nomodeset" or other things to troubleshoot it, not uefi
09:10
!nomodeset
09:10
<ltsp>
nomodeset: Unfortunately, Kernel Mode Setting (KMS) doesn't work well with some cards. To disable it, open /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default and replace "quiet splash" with "nomodeset".
09:10
<alkisg>
Try this ^
09:11
<pxeguy>
cool thankyou alkisg
09:11
<alkisg>
You're welcome; but try it first, and if it doesn't work there are other things to try as well
09:11
<pxeguy>
yes for sure
09:11
I'm still going to push with efi
09:12
because there are about 25 clients
09:12
<alkisg>
OK, but note that it's not really supported by many of the related software
09:12
<pxeguy>
hmmm
09:12
<alkisg>
It will be in a couple of years
09:12
<pxeguy>
alright I understand
09:12
lemme try your suggestion and I'll let you know, should take me 5 mins

cyberorg how can i log in fat client with root? i have root on server and i even "kiwi-ltsp --unpack-image i386, kiwi-ltsp --chroot i386, passwd root and kiwi-ltsp -l2 i386, rcklaoe restart" but sand clock is rounding and rounding on client
10:40

pxeguy: init=/sbin/init-ltsp forcepae nomodeset
10:40
Put it there
10:40
<pxeguy>
okay ty
10:41
on all of the lines with forcepae?
10:41
<alkisg>
The first one should be enough
10:41
<pxeguy>
okay
10:42
done
10:42
can I go ahead and test again, or restart some services?

al-geo, ltsp uses username and passwords created on the server, to log into the client follow https://en.opensuse.org/SDB:KIWI-LTSP_tips_and_tricks#Passwordless_ssh_to_the_client
10:44
or boot the client in fatclient mode, log in as normal user and then use root password you created in the image
10:45
<pxeguy>
fantastic alkisg
10:45
that worked ;)

Hi alkisg, another question, I've managed to boot up in legacy with this client, my resolution is just really off. it's about a 21 inch screen but the rez is at
10:56
1024x768 4:3
10:56
where is the setting to change that?
11:10
<al-geo>
cyberorg thank you :D. now new problem :D in client ip addr shows ip 192.168.50.49/32 and i want 192.168.50.49/22. i did change by myself in server /etc/sysconfig/kiwi-ltsp -> SERVER_IPS="192.168.50.20/22" but after kiwi-ltsp -c it returns to 192.168.50.20
11:13
<cyberorg>
al-geo, you'll have to read networking and dnsmasq documentation, ip addresses to the clients are given by your dhcp server
11:14
depends on what the server uses /22 or /32
11:15
<al-geo>
server uses /22
11:15
in /etc/sysconfig/dhcpd i didnt find option like that
11:16
ok i will figure out something. thank you very much
11:17
<cyberorg>
dnsmasq is used for dhcp

when I set my X_MODE_0 =
11:56
to my desired resolution, it doesn't seem to take it on my client
11:56
I've set XRANDR_DISABLE=True
11:57
<cyberorg>
pxeguy, try to set it manually using xrandr in client terminal
11:57
<pxeguy>
where would I set that?
11:57
in the client terminal
11:58
<cyberorg>
yes
11:58
<pxeguy>
command to set it?
11:58
<cyberorg>
xrandr is the command
11:59
<pxeguy>
xrandr 1600x900?
12:00
<cyberorg>
if it shows when you run xrandr, then xrandr -s 1600x900, see xrandr --help
12:01
<pxeguy>
says "size 1600x900 not found in available modes"
12:06
Ithink it's because I need to set the aspect ratio as well
12:08
<cyberorg>
pxeguy, see xrandr --help (-q) you can only set supported resolutions
12:08
<pxeguy>
oh I see
12:08
highest is 1024x768
12:09
<cyberorg>
then you'd have to ask your #distro channel or google for how to troubleshoot that

"route del default gw 192.168.0.1"
12:27
sorry
12:27
I need to send a root command to run in the "Run command on the selected client" but does not work. Example: I want to run the "route del default gw 192.168.0.1". but not nothing happens.
12:28
already realized that command root does not work perfectly, but when it is a root command does not work.
12:30
also already I tried the command using sudo. did not work.
12:31
already I tried to create a script and run the server, as is the same way only works if you have common User commands if User root command does not work. even giving the necessary permissions.
12:33
also already I tried to give full permission for the file and for anyone using the tag "-s" with the chmod command and also failed.
12:33
Any idea?
12:36
<razielle_tzu>
not really but i'm not surprised that i don't, i'm new to administrating an ltsp system. i just wanted more info for the people that might be able to help
12:36
i wasn't aware that routing applications that way was possible to be honest
12:37
*commands not applications
12:39
<Alyssandro>
Good ! OK. Thank you for your help. I'll keep trying. do not give up yet. I'll try to see the documentation deeply to try to find this problem and solve it on my desktop.
12:40
<razielle_tzu>
ok, good luck

14:32
the above is for xorg.7.log
14:55
<alkisg>
pxeguy1, you didn't include the output of xrandr
14:55
Or is it really empty?
14:56
pxeguy1, now you should remove nomodeset so that the proper driver is used
14:56
Because now you lack acceleration etc
14:57
You'll get a blank screen; to troubleshoot it more easily, install epoptes
14:57
!epoptes
14:57
<ltsp>
epoptes: Epoptes is a computer lab administration and monitoring tool. It works on Ubuntu and Debian based labs with LTSP or non-LTSP servers, thin and fat clients, standalone workstations, NX clients etc. More info: http://www.epoptes.org

14:57
that's from xrandr
14:58
<alkisg>
OK, you can add more resolutions, but it's not the proper solution because now you don't have a driver
14:58
So, remove nomodeset, install epoptes, and we'll continue then
14:58
<pxeguy>
apt-get epoptes?
14:58
apt-get install epoptes?
14:59
on the server right?
14:59
<alkisg>
See the link I gave
14:59
It has documentation for how to install it
14:59
Did you use ltsp-pnp?
14:59
!ltsp-pnp
14:59
<ltsp>
ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
15:00
<pxeguy>
I need to ask my co-worker
15:01
<alkisg>
ls /opt/ltsp/ on the server
15:01
if you see an i386 or amd64 folder there, you *didn't* use ltsp-pnp
15:01
Or paste the output of: ltsp-info
15:02
<pxeguy>
amd64 images
15:02
that's the output of my ls /opt/ltsp
15:03
http://pastebin.com/qbGxdsiY
15:03
<alkisg>
OK then you have a chroot, you're not using ltsp-pnp
15:03
(that means you make it harder for yourself...)
15:03
See the epoptes web site, it has instructions on how to install epoptes both to the server and the chroot
15:04
<pxeguy>
yeah I saw the instructions for the chroot
15:04
hahaha how much harder?
15:04
<alkisg>
Now? Much...
15:04
<pxeguy>
oh boy
15:04
<alkisg>
