Hi guys, i've installed fresh gentoo-amd64 from stage3 and now LTSP. I ask: Can i build x86 clients on 64bits platform?
00:06
<vagrantc>
should be able to, no idea how
00:10
<[GuS]>
vagrantc: I a just in the point of building the client and downloading the stage3 for it. Just i never did it.
00:13
<vagrantc>
i've never used gentoo, but in theory it should be possible. you can do that on debian and ubuntu, i know for sure.

in theory it's possible, not sure whether the code supports it.
02:58
try grepping for m32

:)
09:51* alkisg grands help to maslak
09:52
<maslak>
I need some directions with fixing connection between 1000 mbit server > 100mbit client
09:52
90% of boot probes fail
09:52
my english is weak
09:52
sorry for that
09:52
<alkisg>
Which distro/version are you using?
09:52
<maslak>
ubuntu 10.04.3
09:53
ltsp from distro
09:53
<alkisg>
What messages do you see on the clients, when they fail to boot?
09:53
<maslak>
I just see ubuntu splash
09:53
<alkisg>
!quiet-splash
09:53
<ltsp>
alkisg: 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 .
09:53
<maslak>
before upgrade i was able to press arrow up key and see the console
09:53
<alkisg>
maslak: try what the ltsp bot said above ^
09:54
You upgraded from 9.10?
09:54
<maslak>
is it possible to disable splash for certain thincliens ?
09:54
<alkisg>
Yes, but can't you disable it for all just for a while, while you troubleshoot?
09:55
<maslak>
alkisg: it was 10.04 since it was not stable yet - over 15 upgrades since install
09:55
installed as 10.04
09:55
<alkisg>
Did the clients ever boot without problems since then?
09:55
Or they had problems since the installation?
09:55
<garymc>
good morning Hyperbyte
09:55
good morning alkisg
09:56
<alkisg>
Good morning garymc
09:56
Glad you got everything working :)
09:56
<garymc>
me too, thanks for your input. Hyperbyte sused it int he end
09:56
<maslak>
yes
09:56
<alkisg>
sused? from open-suse? I thought Hyperbyte was a fedora guy... :P :D
09:57
<garymc>
sorry its a Liverpool saying, SUSSED
09:57
as in figured it out
09:57
<alkisg>
maslak: ok, try removing quiet-splash, and check for error messages on clients that won't boot
09:57
<Hyperbyte>
Yeah, sussed. I got it the first time alkisg. :)
09:57
<maslak>
i remember i;ve fixed problem before by defining different filesi in pxelinux.cfg directory
09:57
<Hyperbyte>
But then again, I'm a lot closer to Great Britain than you are. :P
09:58
<maslak>
now 99% of my network is 1000, but two thin clients must stay on old hardware with 100mbit nic
09:58
<Hyperbyte>
:o
09:58
You have two hundred thin clients in your network?
09:59
<alkisg>
Haha, good math there :)
09:59
<maslak>
;)
10:00
alkisg: editing ...../pxelinux.cfg/default will work after just saving file or do i need to rebulid sth ?
10:00
<garymc>
two hundred!!! I have 5 and my firefox runs a little slow
10:01
<alkisg>
maslak: just save + reboot clients
10:01
<maslak>
ok - should be 90% - if not counting network hardware ...
10:01
alkisg: ok - i'll give it a try
10:03
<Hyperbyte>
garymc, what are your client specs?

<maslak>
after dispabling splash i see my station stops after ntpdate
10:19
first 3 attempts to boot were successfull - fourth stopped on *Starting ltsp client.... and ntpdate after that
10:20
alkisg ?
10:21
<alkisg>
maslak: try rebooting a few times, and see if it always stops at the same point, or if it stops at random points
10:22
I suspect it stops at random points.
10:22
!nbd-proxy
10:22
<ltsp>
alkisg: nbd-proxy: Ubuntu 10.04 and 10.10 use a wrapper called nbd-proxy, which is causing networking problems for some people. See https://bugs.launchpad.net/ltsp/+bug/589034. It's been disabled by default in 11.04, see http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/revision/1803
10:22
<alkisg>
maslak: so, you may have to disable nbd-proxy to make the networking problems to stop

10:29
<maslak>
should it be done in chroot for machines or on server side ?
10:29
ok - i found file only on client side
10:31Trixboxer has joined IRC (Trixboxer!~Trixboxer@office.supportdepartment.net)
10:32
<alkisg>
maslak: follow the steps described in the bug report to disable nbd-proxy
10:32
Don't delete files
10:33
<maslak>
if i;m correct i should only apply fix which is replacing a few lines of code
10:34ddave7 has joined IRC (ddave7!~Miranda@109-183-206-28.tmcz.cz)

<maslak>
i see in some of older configurations that i used nocompcache in pxelinux.cfg/
10:38
comment says it waf for fixing old machnes problem... bud don;t remember what exactly...

<garymc>
Hyperbyte : Not sure, just know they are 64 bit and 1gb ram, I think
10:48
looks like 2.8ghz and 2gb ram
10:48
just after booting one then
10:48
sorry I replied late to this, but was out of the office
10:49ddave7 has joined IRC (ddave7!~Miranda@109-183-206-28.tmcz.cz)
10:51
<alkisg>
maslak: I think I'm the only one here that advices people to use nocompcache :D If I told you to put it there, keep it, it makes things faster for old clients with little ram.
10:52
(it even helps with newer clients too)
10:53
<maslak>
after aplying the patch i got kernel panic - not synciing: Attempt to kill init ...
10:53
client got address and after that just stopped ...
10:54
my default pxelinux.cfg looks like that: append ro initrd=initrd.img quiet nbdroot=192.168.0.251:2000 nocompcache
10:59
<alkisg>
If you got kernel panic, you probably didn't get the ltsp_nbd file correctly
10:59
And e.g. you might have downloaded it as a web page (html) instead
11:01
<maslak>
i falloweg instructions here https://launchpadlibrarian.net/49591679/disable-nbd-proxy.patch
11:01
<alkisg>
See my comment #13 in the link I gave you: https://bugs.launchpad.net/ltsp/+bug/589034
11:01
<maslak>
but i assume i did it wrong way - becouse i removed lines marked - , added + and those which are without a lead
11:02
<alkisg>
Also, how much RAM do your clients have?

11:06
sorry
11:07
i've corrected the patch - enabled noquiet mode and now it boots, but says nbd0 - unknown partition table ... but i have nbd swap disabled - is something else using nbd ?
11:08
<Hyperbyte>
garymc, your thin clients are 2.8ghz and 1 GB ram?
11:09
** 2 GB
11:09
<garymc>
2GB
11:09
I THINK
11:09
<Hyperbyte>
...
11:09
<garymc>
THE SCREEN GOES OFF PRETTY QUICkly :S :P
11:09
caps sorry
11:09
<Hyperbyte>
That's why there's a 'pause' button on your keyboard
11:09
In a local xterm
11:09
<muppis>
maslak, warning about unknown partition table can ignored.
11:10
<maslak>
ok
11:10
muppis: thnx
11:10
<Hyperbyte>
Type 'cat /proc/cpuinfo' and 'cat /proc/meminfo'
11:10
And pastebin that
11:10
<maslak>
alkisg: great thanks for your help - now it works fine 10/10 boots ok
11:11
<garymc>
loading xterm, i forgot
11:11
<Hyperbyte>
Type !localxterm
11:11
(in here)
11:11
<garymc>
!loacxterm
11:11
<ltsp>
garymc: I do not know about 'loacxterm', but I do know about these similar topics: 'localxterm'
11:12
<garymc>
!localxterm
11:12
<ltsp>
garymc: localxterm: while sitting on a thin client, open a gnome terminal. In that, run: ltsp-localapps xterm. An xterm will open. That xterm runs locally, so any commands you enter there are executed directly on the client.
11:13
<maslak>
Guys is it possible to run wine as a localapp ?
11:13
<garymc>
ok

11:15Parker955 is now known as Parker955_Away
11:15
<garymc>
I cant scroll it either
11:16
<Hyperbyte>
garymc, with | you can pipe output to another command. 'more' is a scrolling interface for output
11:16
cat /proc/cpuinfo | more
11:16
<garymc>
I can see 2.8ghz chip speed and 2gb memeory
11:16
2mb cache
11:16
<Hyperbyte>
That's insane for a thin client.
11:17
You realize thin clients work with much, much less?
11:17
<garymc>
yeah I got them for £20 each
11:17
so thought super
11:17
they will do and they are quite small
11:17
<alkisg>
maslak: sure, it's possible
11:17
<Hyperbyte>
garymc, you should consider running some applications locally on the thin client.
11:18
<garymc>
dont know how to
11:18
<Hyperbyte>
Just like you run 'ltsp-localapps xterm' you can run 'ltsp-localapps firefox' if Firefox is installed on the client.
11:18
<garymc>
i would like to run firefox locally
11:18
how would I install firefox on the client
11:18
<Hyperbyte>
Alternative, you could implement fat clients, and run the -entire- desktop locally, taking the strain off the server and network, and putting it on the client.
11:18
<garymc>
is that a big task to do?
11:18
<Hyperbyte>
Not really
11:18
!fatclients
11:18
<ltsp>
Hyperbyte: fatclients: You may find some info about the Ubuntu/LTSP implementation of fat clients at https://help.ubuntu.com/community/UbuntuLTSP/FatClients
11:19
<garymc>
would they still have to log in on the server?
11:19
<Hyperbyte>
Yes
11:19
<garymc>
ok well that sounds good
11:19
<Hyperbyte>
And they still use one collective network image, served via the network.
11:19
<garymc>
ok
11:19
so I have a test client setup to the network where do I start
11:19
do i need to install ubuntu on it?
11:20
<Hyperbyte>
With thin clients, the client boots a minimal OS, logs into the server, and starts a whole desktop on the server.
11:20
With fat clients, the desktop is started on the client rather than the server.
11:20
Start by reading the manpage above. Don't just dive into this by typing all kinds of commands and doing things.
11:21
First read the page above, see what's involved, consider where you might run into problems, which things you need to learn about before doing this.
11:21
You have a working setup, make sure you don't kill it by diving into something that's, at this moment, a little over your head. :) Learn first.
11:23
<maslak>
about localapps: I;ve noticed that running firefox as localapps is good solution, but there were some problem opening files on the fly - let's say pdf documents... it did,t work same way as it works on server side
11:23
<garymc>
can you have a mix of fat and thin clients on the server?
11:23
<Hyperbyte>
maslak, because the local Firefox uses local resources. If you don't have a local PDF viewer, it won't open PDF's.
11:24
<maslak>
nowadays - most of office work is done via browser
11:24
<Hyperbyte>
maslak, you can however configure Firefox to use the remote PDF viewer on the server. 'ltsp-localapps' starts an application on the client, from the server. 'ltsp-remoteapps' starts a program on the server, from the client.;

11:24
<Hyperbyte>
garymc, not sure. You have some slower clients as well?
11:24
<maslak>
remoteapps - never heard ab that ;)
11:24
<Hyperbyte>
maslak, if you use evince for PDF viewing, you would configure the local Thunderbird to use 'ltsp-remoteapps evince' for PDF viewing
11:26
<maslak>
right now i have testing enviroment on aprox 20 thin clients - target is to move over 80 windows machines to ltsp solution in ltsp cluster
11:27
<Hyperbyte>
maslak, good job. :-D
11:27
Company?
11:27
<maslak>
if it;s possible to run remote aps ad default settings it;s really great solution, but if it;s nesesarry to configure it per user it is a problem
11:27
yes
11:27
company ;)
11:28
<garymc>
i have slower thin clients but I dont use them, only if I needed to use them in say an emergency
11:28
<maslak>
I have one company and one school
11:28
<Hyperbyte>
garymc, you could probably use a mix, but they'll be completely different desktops. They wouldn't use the same configuration.
11:29
maslak, Firefox supports global settings. Also, configuring things per-user you could easily do with a script.
11:29
For example, I have a softphone and generate user configuration automatically on login.
11:29
You can place a link in /etc/xdg/autostart to a script that runs on login
11:29
The script can set all the appropriate configuration.
11:30
And it'll run from the user account too, which is beneficial for what you want to do.
11:30
<maslak>
there were two problems up today... some windows apps which are not able to run under wine - and performacje of server - If i;ll manage to port wine to run as localapp on client this should give me a lot of cpu and ram on a server
11:30
Hyperbyte: Thanks for pointing me right direction
11:31
<Hyperbyte>
maslak, client specs?
11:31
<maslak>
most of them dell gx 620 : 1gb ram + nvidia graphics
11:31
some are older dells

it's good ;)

maslak, what kind of Windows application do you need to run?
11:32

but i didn,t know there's such sollution as remote apps

11:33

Don't know it.

oficially noone, anywhere did that ;) - i got it running fine on server side

they provide software to build software ...
11:35
and my great bos bougt software written in software ;)
11:36
<Hyperbyte>
Ah
11:36
<maslak>
so we paid for app + license to run app + windows licenses :)
11:36
<Hyperbyte>
Hm
11:36
Well, not sure if this is a solution
11:36
<alkisg>
If you can run it on the server, then you can run it on clients too
11:37
<Hyperbyte>
But I have some software that doesn't want to run on Linux either...
11:37
<maslak>
wine has some bugs working under ltsp
11:37
<Hyperbyte>
I applied a multi-user RDP login hack to Windows XP Pro, and use RDP from the thin client desktops to run the Windows software.
11:37
<maslak>
mainly dx related
11:37
and graphic acceleration
11:38
Hyperbyte: I use this sollution elsewhere - but this company is too big to provide such sollutions ;)
11:39
<Hyperbyte>
maslak, if lots of people use it, then yeah... that's gonna be a problem.
11:39
<maslak>
LTSP has nice feature to run automatically rdp client on different screens, so some of my users have linux and windows "running" on thin client ;)
11:39

I run the RDP directly on the thin client desktop
11:40
<garymc>
with FaT clients do you need to install anything on the Client?
11:40
<Hyperbyte>
Not even as a local app either. :o
11:40
<alkisg>
maslak: local wine wouldn't have any remote-X-related problems
11:40F-GT has joined IRC (F-GT!~phantom@ppp121-44-18-3.lns20.syd6.internode.on.net)
11:40
<Hyperbyte>
garymc, no. LTSP fat clients, like thin clients, do not require, nor use a harddisk. They netboot.
11:41
Everything you want to install 'on the client', you need to install on the server, in the /opt/ltsp/ chroot.
11:41
<maslak>
alkisg: app i;m using is directx related - there was a problem about year ago that forced me to use vesa driver or nvidia cards to run it right way - otherwise my clients thin or fat (up to 4gb ram) were crushing when starting UniPaas
11:42
<alkisg>
maslak: which problem? Local wine should be the same, with ltsp or not.
11:42
<Hyperbyte>
UniPaas is a horrible name for anything computer related by the way. It sounds like some evil villain from a bad SciFi movie...

If the application made isn't too complicated, you could consider rewriting it. ;-)
11:44
Make it into a nice web application, so they can easily run it from home as well. ;-)

<maslak>
BTW: is there any sollution which will allow me to cut traffic on my thin client when user goes into a flash site or plays yutube video ?
11:44
<Hyperbyte>
Yep. Firefox as localapp. :)
11:45
<maslak>
hyperbyte: that;s the problem - i;m not a programmer and he won;t pay a single cent more than he did for our :proud sollution"
11:45
<Hyperbyte>
Local applications output directly to the client's X, they don't go via network.
11:45
<maslak>
is it possible to run just flashplugin as localapp ? :)

11:46
<Hyperbyte>
garymc, no.
11:46
<garymc>
imagine I messed up the current config, my head would be BURNT!!
11:46
<Hyperbyte>
Did you read the entire fat clients document
11:46
?
11:46
<garymc>
yeah, but understanding and reading are two differnt things :P
11:46
<Hyperbyte>
Well, work on understanding then. :)
11:47

It's good to understand what you are doing before you are doing. :)
11:48
maslak, interface binding/trunking in Ubuntu is a piece of cake. alkisg configured it for me in ten seconds IIRC. Combine that with your local Firefox, and your problems are history.
11:48
<garymc>
i think my main problem would be getting this internet connection NAT to work on the FAT clients
11:49Parker955 is now known as Parker955_Away
11:49
<garymc>
Could I work on this while everyone is still logged in and working? Without disprupting them?
11:49
<Hyperbyte>
garymc, NAT is something you configure on the server, not on your modems/etc.
11:49
You have to enable NAT on the LTSP server
11:49
!nat
11:49
<ltsp>
Hyperbyte: I do not know about 'nat', but I do know about these similar topics: 'nx', 'nfs'
11:49
<maslak>
ok - alkisg, Hyperbyte - thank you verry much for your help - one beer one me if you;ll ever come to poland ;)

11:52
<Hyperbyte>
garymc, you can. If it were up to me, it'd be outlawed through the entire country though.
11:52
<garymc>
i used to smoke weed, probably why i have to read things over and over again.
11:53
why would you outlaw it? cos of the unwanted tourism or the use of it itself?

Because of the bad smell, the criminality it brings to the Netherlands, because of the health risks especially to young people
11:54
But mostly because of the irresponsibility it brings out in people.
11:54
<garymc>
what about prostitution?
11:55
<Hyperbyte>
Prostitution is confined to certain neighborhoods. It doesn't bother me.
11:55

hmmm
11:55
intresting

Street prostitution was outlawed a while ago.

12:00

You can assume the information in the document is up-to-date.
12:00
<garymc>
and im guessing I have already ran the first Prep commands so wouldnt need to run them again
12:00
<Hyperbyte>
Let's make it simple
12:01
<garymc>
eg; sudo apt-get install ltsp-server-standalone
12:01
<Hyperbyte>
Start with things that you can set up for fat clients, without bothering the thin clients
12:01
No, you already have ltsp-server-standalone
12:01
LTSP for thin clients and fat clients is same software, just different configuration.
12:01
<garymc>
ok so prep is not needed to follow
12:01
ok
12:01
<Hyperbyte>
When you are going to do this, you need to make sure you don't erase your thin client config, because that'll cause angry faces. =)
12:01
Start with setting up NAT. Type !nat
12:02
<garymc>
!nat
12:02
<ltsp>
garymc: nat: To set up NAT on your LTSP server, see: https://help.ubuntu.com/community/UbuntuLTSP/ThinClientHowtoNAT
12:02
<garymc>
ok Creating ltsp-build-client.conf , will that mess with current setup?
12:02
<Hyperbyte>
NAT is something you need for fat clients and localapps, but won't make a difference for thin clients. :)
12:03
garymc, I don't think it will, if you build a different chroot for the fat clients.
12:03
alkisg is our resident fat client expert.
12:03
<alkisg>
ltsp-build-client.conf is only used when one runs ltsp-build-client
12:03
It affects both NEW thin and fat chroots
12:03
Not old chroots
12:04
<garymc>
old chroot is one currently being used nad not booted up yet?
12:04
*and
12:04
<alkisg>
It's much easier to mv the old chroot somewhere else, before creating a fat chroot. This way no dhcpd editing is needed
12:04
old chroot = your current /opt/ltsp
12:04
<garymc>
dhcpd editing ... ARRRRH

oh ok
12:04
:)
12:05
<Hyperbyte>
But after taking in this information, forget about fat clients for a while, and set up NAT.
12:05
<garymc>
ok
12:05
<Hyperbyte>
Use the !nat guide, but take care with the last step of '5' in the document. Because your use NetworkManager, it needs to go a little different.

12:21
hyperbyte part 3 of guide
12:24
so i is stuck, as there is no explanation if it doens twork here :S
12:25

Type ipconfig /all
12:25
Does that show the default gateway?
12:25
<garymc>
on my pc laptop?
12:26
<Hyperbyte>
Yeah, the Windows one.
12:26
<garymc>
nope doesnt show it
12:26
media state disconnected
12:26
??
12:27

Means cable isn't plugged in. =)
12:27
<garymc>
it is
12:27
i can also PXE boot this lappy
12:27
so cable definatleyis connected
12:27
<Hyperbyte>
So ipconfig /all doesn't show an IP address?
12:28
<garymc>
nope
12:28
ok it does now
12:28
its shows 192.168.1.254
12:28
not .0.254
12:29
<Hyperbyte>
Check your dhcpd.conf
12:29
<garymc>
but thats showing the wirless and bluetooth adapters ip
12:29
on the lappy
12:29
i switch that off and it shows nothing
12:29
<Hyperbyte>
Then it's connected via wireless, not the local LAN.
12:30
<garymc>
LAN is supposed to supercede it it hought
12:30
<Hyperbyte>
Just use a regular thin client, much easier.
12:30
Reboot a thin client and type 'ip route show' in a local xterm.
12:30

the first two of 5 ?

Hi Everybody. I have an interesting problem with the LDM screen. The time on that does not give me the correct time. Is LDM getting it from the client's BIOS?
13:01
<Hyperbyte>
garymc, http://pastebin.com/4a0UD77X
13:02
<alkisg>
charles_: yes, you can set TIMESERVER in lts.conf to automatically sync the time
13:02
<Hyperbyte>
charles_, it's getting it from the clients internal clock, yes. You can get the thin client to sync the time by setting up an NTP server and ... doing what alkisg just said. :)
13:03
<garymc>
Hyperbyte : Done
13:03
<charles_>
alkisg: Hyperbyte: Thanks for that. A little bit added to my work list.
13:04

garymc, naturally.
13:04

13:12

See guide.
13:13
<garymc>
should i reboot client as I couldnt ping nothing
13:13
<Hyperbyte>
. Test: Reboot the test PC again, to update its DNS server. Try pinging a real world server from the test PC by name, eg
13:13
Please -read- guide.
13:14
<garymc>
yes it works
13:14
I had to reboot client first
13:14
:)
13:14
so Nat works
13:14
<Hyperbyte>
It says so in the guide. :)
13:14
<garymc>
There you go
13:14
where from here?
13:15
I know back to other guide but what step should I start on which will not break my current system?
13:16
<Hyperbyte>
Client chroots (the actual client software) are kept in /opt/ltsp/
13:17
There are currently two folders there on your system, amd64 and images.
13:17
<garymc>
ok
13:17
<Hyperbyte>
'images' contains the NBD network images LTSP creates - do not touch! 'amd64' is your current thin client software.
13:17
Rename that folder. 'mv amd64 amd64.thin', for example
13:18
Then you can build a new client, without destroying the old.
13:19
Are you sure you need a mixed setup, or will fat-clients only work for you?
13:19
<garymc>
FAT CLIENTS will be fine as long as I buy more of the same workstations I have
13:20
<Hyperbyte>
Can be different. Like with thin clients, it'll work with any hardware that is supported. Can be different machines. As long as they're not too slow or have too little ram.
13:20Gadi has joined IRC (Gadi!~romm@ool-18bbe47a.static.optonline.net)

<garymc>
so right now what do I need to do
13:20
:s
13:21
<Hyperbyte>
Follow the guide. :)
13:21
<garymc>
from which point
13:21
this part : Creating ltsp-build-client.conf
13:21
<Hyperbyte>
Creating ltsp-build-client.conf
13:21
Yep.
13:21
<garymc>
and I wont break nothing
13:21
?
13:21
<Hyperbyte>
But only -after- you have renamed the amd64 directory as I said above.
13:22
You will replace thin clients with fat when you run sudo ltsp-build-client
13:22
But since you still have the amd64.thin folder, you -can- go back if needed.
13:22
Also, you won't disturb any currently logged in users.
13:22
Only new logins.
13:30
<garymc>
so if I type :
13:30
mv amd64 amd64.thin
13:30
that will rename it?
13:30
<Hyperbyte>
mv <oldname> <newname>
13:31
Don't forget to 'cd' to the correct folder first.
13:31
<garymc>
where is that folder?
13:31
<Hyperbyte>
15:16 <Hyperbyte> Client chroots (the actual client software) are kept in /opt/ltsp/
13:31
<garymc>
is it /etc/ltsp?
13:31
ahhh sorry
13:32
ok renamed

Hi guys, i've built a LTSP 32bits client inside Gentoo 64Bits env. Now, when i try to enter to the chroot env i got: chroot: failed to run command `/bin/bash': Exec format error. I used the cmd: linux32 chroot /opt/ltsp/x86/ /bin/bash. Any tip?
13:40
<garymc>
ok
13:40
<Hyperbyte>
[GuS], hm... not sure about Gentoo... setarch i386 chroot /opt/ltsp/i386/
13:40
Try that.
13:41
<[GuS]>
Well in gentoo the common is linux32. I will test that
13:41
<Hyperbyte>
No tip then. :)
13:42
Perhaps the 'ltsp-chroot' command works better, if Gentoo has it.
13:42
<[GuS]>
Hyperbyte: setarch: i386: Unrecognized architecture, also x86 not works. But well, supposed that linux32 should work

Weird question, but is the LTSP server still responsive?
14:03
<garymc>
ubuntu unpacking, does that mean its finished downloading and is now installing
14:04
<Hyperbyte>
Probably. I've never actually done this before. :-D
14:04
<garymc>
dont say that
14:04
<Hyperbyte>
Hahah
14:04
alkisg is our resident fat client expert. :)
14:04
He can fix any problem, if you buy him a beer.
14:05
Still you know, might as well let it finish building now... clients should be ready to go when it's done.
14:05
<knipwim>
[GuS]: i just use the chroot command
14:05
no linux32
14:06
to chroot into my 32bit clients on my 64 bit server
14:06
never had any problems with that
14:06
<garymc>
how do I know if its booting FAT or THIN?
14:06
<[GuS]>
knipwim: i cant, it gives me that error... indeed i did it before and works,... now does not
14:06
:(
14:06
Since o reboot my server now i cant... i dont know why

garymc, easy, you open an xterm. :)
14:07* knipwim worries
14:07
<Hyperbyte>
If the xterm opens on the client, it's fat, if it's on the server, it's thin.
14:07
<knipwim>
havent restarted my server for more than a year now
14:08
<[GuS]>
knipwim: is just a new server, i moved the place and restarted...
14:08
<Hyperbyte>
Also you can check what processes are running, to make extra sure. If you have an xterm on the client and type "ps aux" you should see a whole boatload of Gnome processes
14:08
<knipwim>
[GuS]: so both the chroot and the linux32 chroot cmds are giving you grief?
14:09
<[GuS]>
knipwim: yes, which is weird.
14:11
<knipwim>
i'm not really an expert (and going away now)
14:11
but have you checked the linux32 man page?
14:12
maybe there are some tips
14:13
perhaps use linux32 chroot /opt/ltsp/x86 /bin/sh ?
14:14
going from this screen now
14:15
<[GuS]>
Oks, i will test with sh

14:15
<knipwim>
you could file a bugreport or ask in #gentoo
14:15
<[GuS]>
either works grrr... i wonder why was working before
14:15
<knipwim>
it works!?
14:16
<[GuS]>
knipwim: nope... i will ask in gentoo then..
14:16
<Hyperbyte>
Pardon my ignorance in Gentoo matters
14:16
But I'd guess /bin/sh is referring to the /bin/sh outside the chroot, rather than inside
14:17
So it tries to run 64-bit /bin/sh inside 32-bit chroot
14:17
Possible?
14:17Gadi has left IRC (Gadi!~romm@ool-18bbe47a.static.optonline.net, Ping timeout: 260 seconds)
14:17
<Hyperbyte>
What happens when you leave out /bin/sh completely? Just linux32 chroot /opt/ltsp/x86 ?
14:17
<garymc>
ok thats finished
14:17
<[GuS]>
Mmm could be..
14:17
<garymc>
should I boot client now?
14:17
<[GuS]>
Hyperbyte: same error
14:18
<Hyperbyte>
garymc, try
14:18
[GuS], okay... worth a try I guess...
14:18
<ry>
have any of you managed to get 4 or more screens working on a wyse r90?
14:18
(running suse)
14:18
<[GuS]>
I think i should test to build the client again...
14:21
<TheMatrix30001>
should i add teh stgraber ppa?
14:21
<garymc>
Hyperbyte : seems to be running slow as shit!!!
14:22
<Hyperbyte>
garymc, seriously?
14:22
<garymc>
yeah firefox loads dead slow
14:22
and it was asking for security certs and all that
14:22
<[GuS]>
knipwim: building the client again fails when the ltsp script tries to chroot with linux32.
14:22
<garymc>
I take it its very hard to revert
14:22
<[GuS]>
Something is wrong in my system...
14:23
<garymc>
secerity certs cos I connect to a https site
14:23
never used to ask that
14:23
<Hyperbyte>
garymc, it's easy to revert, but let's try and fix this first, ok?
14:23
<garymc>
ok
14:24
<Hyperbyte>
Open a regular Gnome terminal. Is it running on the client, or server?
14:24
<dberkholz>
Hyperbyte: no, that's not how chroot works
14:24
the final command is what gets executed upon switching into the new root
14:24
<garymc>
actually seems to be ok
14:25
hold on
14:25
<Hyperbyte>
dberkholz, I was just guessing. ;-)
14:26
garymc, maybe it was slow because of all your clients booting at once?
14:27
<TheMatrix30001>
i think the later
14:27
<garymc>
no only one booted
14:27
so I wanna check xterm what should I type
14:28
<[GuS]>
dberkholz: I dont know what could it be... chroot on 32bits is failing in anycase... theonly diff i did before restart the server was compiling the kernel
14:28
<Hyperbyte>
garymc, what does your prompt look like?
14:28
<[GuS]>
I will dig what i changed.
14:28
<garymc>
gary@ltsp21: ~$
14:28
<dberkholz>
can you run anything 32-bit on the server? wonder if you're missing x86 emul in your kernel or something
14:29
check your server kernel config for CONFIG_IA32_EMULATION
14:31
<Hyperbyte>
garymc, that's fat, then. It's slow with starting programs, right?
14:31
And after the programs have started it's fine, right? It's not slow with clicking menu's or dragging windows?
14:31
<garymc>
a little
14:31
no its fine
14:31
one thing is, each FAT client has the wrong dates and times in them
14:32
is that just a personal setting?
14:32
for each unit
14:33
<Hyperbyte>
For that you need to set up a timeserver on the LTSP server, and set TIMESERVER and TIMEZONE in lts.conf
14:34
<garymc>
I thought that was already done
14:34
<Hyperbyte>
Run sudo apt-get install ntp on the server
14:34
<garymc>
ok
14:34
command finished
14:34
is that it?
14:35
<Hyperbyte>
Type ntpq
14:35
And then pe
14:35
<garymc>
done
14:35
dont know what any of it means though
14:35
i see IP and offset etc
14:36
<Hyperbyte>
Good
14:36
Now edit your lts.conf
14:36
And set TIMEZONE and TIMESERVER
14:37
TIMESERVER=<ip of your ltsp server>
14:37
<garymc>
it just locked
14:37
<Hyperbyte>
TIMEZONE=Europe/London
14:37
Locked?
14:37
<garymc>
my terminal in mac locked
14:37
<Hyperbyte>
I don't understand what that means.
14:39
<TheMatrix30001>
what is your opinion of using NBD swap?
14:40
<garymc>
lts.conf cant find it again :S
14:41
terminal keeps crashing :S
14:41
<Hyperbyte>
garymc, SSH to the server
14:42
<garymc>
on my mac via ssh
14:42
i have done]
14:42
<Hyperbyte>
Your SSH terminal to the server keeps crashing?
14:43
<garymc>
yes its ok now
14:43
musta been my net connection
14:43
I cant find lts.conf
14:43
find -name lts.conf
14:44
<Hyperbyte>
find . -name "lts.conf"
14:44
<garymc>
i just typed that command above
14:44
<Hyperbyte>
But it's in /var/lib/tftpboot/ltsp/amd64/
14:44
<garymc>
withouth the .
14:44
<Hyperbyte>
Actually, should be find / -name "lts.conf" to search entire disk
14:44
But the path I just gave you is correct.
14:44
<m4xx>
what's the proper way to use the evtouch driver? "X_TOUCH_DRIVER = evtouch_drv.so" ?
14:46
<garymc>
ok thanks
14:46
ill reboot client now see if it works
14:46
192.168.0.254 is the IP I used TIMESERVER, thats correct yes?
14:49
<Hyperbyte>
16:37 <Hyperbyte> TIMESERVER=<ip of your ltsp server>
14:49
<garymc>
Hyperbyte : Just rebooted two clients one is still at slpash screen, other has been veyifying password for a while now and no movement
14:49
<Hyperbyte>
garymc, that's nuts. You need alkisg for this stuff.
14:50
<garymc>
shit
14:50
<Hyperbyte>
Not shit. :P
14:50
alkisg is very helpful and nice. :P
14:50
<garymc>
timeserver
14:50
just to confirm my ip of ltsp server is 192.168.0.254
14:50
is it?
14:50
<Hyperbyte>
Type 'ifconfig' on the server
14:51
<garymc>
yep
14:51
eth0 or eth1
14:51
eth0 is 192.168.0.254
14:51
I think NTP has messed shit up
14:51
<Hyperbyte>
I think you need to debug a little.
14:52
Type 'top' on the server
14:52
<garymc>
no eth1 is that ip above
14:52
<Hyperbyte>
Is there some process using insanely much CPU?
14:52
<garymc>
nope
14:52
2 is highest
14:53
working now
14:53
<Hyperbyte>
Okay, ctrl+c
14:53
Type 'free -m' on the server
14:53
How much swap is free?
14:53
<garymc>
8476
14:54
<Hyperbyte>
Also good
14:54
<garymc>
time and date still wrong on Clients
14:54
<Hyperbyte>
Server should have no reason then to kill your SSH connection
14:54
<garymc>
cool
14:54
<Hyperbyte>
Type netstat -lpn | grep ntpd
14:55
<garymc>
ok
14:55
<Hyperbyte>
(I don't think that's correct command, moment)
14:56
Actually, yes, that is correct.
14:58
<garymc>
ok so what am i looking for
14:58
should i paste it?

15:01
any advice please
15:02
<Hyperbyte>
That paste looks okay by the way. It might simply be that your LTSP server isn't syncronized completely yet.
15:03
<garymc>
ahh ok does that take long?
15:03
or doe sit need a reboot?
15:03
<Hyperbyte>
No idea. You can check with 'ntpq' and then 'pe'
15:04
If the 'offset' looks reasonable (e.g, nothing over 5 seconds), it should be doing okay
15:04
Gone now!

I've removed the previous driver i attempted to use and installed xserver-xorg-input-evtouch. This is the entry i have my lts.conf: http://paste2.org/p/1640533 The mouse still moves to the top left of the screen no matter where i touch. Any ideas?

15:47

/opt/ltsp/x86 does exist right?
15:47

Also, tried to build fresh ltsp client and it fails cause of the same problem... which is weird
15:48
m4xx: yes..
15:48
ehmm... like i said, was working before restarted the server
15:48
<m4xx>
do you need to mount proc and sys?
15:48
n/m
15:50
<[GuS]>
I discovered this since i wanted to modify some stuff on the chroot... and now i cant enter and neither i cant rebuild ltsp client... is very weird
15:51
<m4xx>
update the image or re-create it?
15:53
<[GuS]>
m4xx: you mean the ltsp client?
15:53
<m4xx>
yeah
15:53
<[GuS]>
like i said, i cant.... the ltsp client script gives me the same error in the step that tries to enter the chroot.
15:53
So, something happen to my system env.
15:54
And i dont know what... since i did it sucessfully yesterday.

hi ppl, hi alkisg :) do you know if I can install GNU on a usb pen like it were a "normal" hd driver (so grub, ext4, swap, etc) and have it boot from a PC? Or just FAT32 is recognized and boot has to be particular?
16:01
I have to provide GNU to teachers's computers in a easy way
16:01
(well, if anyone else knows the answer, is welcomed)
16:03
<alkisg>
I don't know about GNU, but you can install e.g. ubuntu on a usb pen or external hard disk, sure
16:06
<markit>
alkisg: I've found this answer: http://tuxradar.com/content/how-install-linux-usb-flash-drive seems that live cd on usb can be modified, I thought was mounted read only
16:06
also he says livecd installation are optimized to reduce disk writes, so should preserve usb live longer
16:07
<garymc>
alkisg : do you know how I get my FAT clients to display correct date and time?
16:08
<markit>
I ask because I was trying to boot from usb on my children pc but seems that FAT32 are recognized, while Kubuntu usb live is ignored. now I seen in dmesg that there are other kind of problems I did not noticed :(
16:09
urgh, is not recognized at all
16:09
I can't re-partition or reformat or anything (8gb usb sigh)

Click 'Expand all' there
20:56
Then search for the file 'ltsp-init-common' on your server
20:56
Presumably /opt/ltsp/amd64/usr/share/ltsp/ltsp-init-common
20:57
Then search for the line in red on the revision webpage, and replace it with the line in green.
20:57
Be extremely careful not to make any mistakes though, and triple-check the line after you've modified it.
20:58
Has to be 100% exact.

Hyperbyte : done all that, do I need to restart anything?
21:42
<Hyperbyte>
After you modify anything in /opt/ltsp/ (the client) you need to run ltsp-update-image
21:42
And then reboot the client.

Fat clients be ok?

<Hyperbyte>
Sorry, I meant break fat client boot.
22:01
Just try it man... if it doesn't work, just fix.
22:01
Plus, if you copy-pasted the line you can't go wrong.
