is there a management interface in ltsp-cluster?
02:48
<X-TaZ>
Yes

<X-TaZ>
( following the example install )
02:49
<Appiah_>
I read it once and it feelt like it was going to take time to setup
02:49
I have to test it sometime
02:50
<X-TaZ>
Well it is hard to install. And many things are not written in the OpenVZ doc
02:51Bushmills has left #ltsp

<Appiah_>
I was hoping after you set it up you could make a custom cd install for deploying application servers where you just type in IP/GW/DNS and then just wait
02:52
that would be the goal in my setup
02:53
<X-TaZ>
It could be great
02:53
I don't know how is it feseable
03:08
<Appiah_>
with a couple of scripts ;)
03:08
well maybe you will have to do a bit more then just that

_UsUrPeR_, cliebow: morning, got some new info on my intel 945 troubles from yesterday
08:04
<cliebow>
what did you find?
08:04
<pmatulis>
_UsUrPeR_, cliebow: after removing a dvi adapter and replacing with a native cable i was able to boot my client from the local drive
08:04
but the ltsp boot still doesn't work
08:05
it is using the intel-agp module
08:05
anyway, i have dmesg, lspci, and xorg log if you're interested
08:05
<cliebow>
pmatulis, what did you find?
08:06

<pmatulis>
agpgart-intel
08:20
can i plug this in with XSERVER option?
08:20
<ogra>
no
08:20
thats not a driver
08:20
thats a kernel module
08:20
the x driver is simply called intel
08:20
<_UsUrPeR_>
pmatulis: is the chipset the same as this? http://www.disklessworkstations.com/cgi-bin/web/info/ltsp_t1520.html?id=yyWPYmic
08:21
If so, I have some xorg configs I could send you that may help.

<ltsppbot>
"pmatulis" pasted "lscpi output" (29 lines) at http://pastebot.ltsp.org/338
08:24
<pmatulis>
ogra: so i can use 'intel' for XSSERVER ?
08:26
_UsUrPeR_: no, yours is 945GSE, mine is 945GME
08:26
<_UsUrPeR_>
ahh
08:27
<pmatulis>
_UsUrPeR_: but i'm still eager to see what you did
08:27
<_UsUrPeR_>
ogra is correct though: the xserver should be google
08:27
err... intel
08:27
mid-conversation on another topic :)
08:27
<pmatulis>
_UsUrPeR_: a google driver, oh boy
08:27K_Wolf has joined #ltsp
08:27
<pmatulis>
_UsUrPeR_: just get to see google.com?
08:28
<_UsUrPeR_>
heh. at least i didn't say "boobs" or something ;)
08:28
seriously though: XSERVER = "intel" should work for you
08:28* pmatulis goes to try
08:29
<_UsUrPeR_>
pmatuils: which ubuntu version are you using?
08:30
<K_Wolf>
Hi people. Have any of you experienced slow printing under LTSP clients. In my case I'm trying the label printer Zebra TLP 2844 connected to a thin client.
08:30
<cliebow>
_UsUrPeR_, you are banished 8~)
08:31
<_UsUrPeR_>
noooo!
08:32
<pmatulis>
_UsUrPeR_: 9.04
08:33
<_UsUrPeR_>
pmatulis: ok. did using XSERVER = "intel" work for you?
08:33
<pmatulis>
_UsUrPeR_: booting now
08:34
<X-TaZ>
K_Wolf, do you have high ping between your server and your printer ? because printing protocol needs acknowledgements between each paquets. With high ping it becomes,very slow
08:35
<pmatulis>
_UsUrPeR_: no, it failed again
08:35hanthana has joined #ltsp
08:35
<_UsUrPeR_>
:/ ogra: any ideas?
08:41
<pmatulis>
_UsUrPeR_: i confirmed with getltspcfg that XSERVER = intel

<ogra>
pmatulis, as i told you, you need to specify the output device and either Gadi or stgraber know how to do that
08:48
<pmatulis>
ogra: right, i just wanted to cover the basics first
08:48F-GT has quit IRC
08:48
<ogra>
if it works with a local jaunty install the X detection should be fine so far
08:49
<pmatulis>
one thing worth noting is that this client has 2 dvi outputs
08:50
<K_Wolf>
X-TaZ: At my scenario the user open a 'rdesktop' session to Windows Server 2k3 to use his application. The program generate a CPL file (native printer script), thats sended from a batch file ('copy file.pcl \\ltsp\printer)
08:50
<ogra>
just wait for Gadi, he knows the output hack
08:50* pmatulis goes to try his other malfunctioning intel client
08:51
<pmatulis>
ogra: ack
08:53
<K_Wolf>
X-TaZ: it`s very slow when printing more than 1 file. Have you any idea about tests that I could do to debug it?
08:53
<X-TaZ>
I'm sorry i have no idea bro
08:54
<K_Wolf>
ok, thanks anyway :)

Morning guys
09:39
I have a lab that is acting funny, 25 of the exact same client, 2 of them boot to the point where they will rdesktop to a TS and then the screen keeps flashing grey off and on
09:40
the grey screen has a mouse X but thats it

09:59
<jammcq>
hey cliebow
09:59
how's it going?
10:01
<treyh>
hey got a question for you guys
10:01
<cliebow>
Going great..but losing market share all the time
10:02
i thinkmy old linuxlab is going away
10:02
<jammcq>
ooh, bummer
10:02
<treyh>
have a lab of 25 clients, exactly the same hardware, over the last few days random clients will but when they get to the point of running rdesktop the screen just blinks grey then black
10:03
looks like it's going from screen01 to screen02 but screen two only shows a grey screen with a X mouse
10:03litlebuda has quit IRC
10:09
<epsas>
weird
10:10
<treyh>
whats even more strange
10:10
is that in the last 3 days, it's been 1-3 units each day
10:10
and they're always different
10:12
<epsas>
have you set up shells on the console so that you can debug?
10:14carl has joined #ltsp
10:15
<treyh>
yes
10:15
not sure what to look for though
10:17
<carl>
Hello all, I just sent out a email to the discussion list but thought I would jump on here. Are there any fundamental difference in setting up LTSP on Ubuntu Server Edition as opposed to desktop edition?
10:17
<alkisg>
treyh: limited sessions in your windows server?
10:17
(licenses in the terminal server, I mean...)
10:17
See the windows logs
10:17
<treyh>
alkisg: no
10:17
alkisg: I'll double check
10:18
<johnny>
carl, not in particular
10:18
except you might have to install more programs..
10:18
<carl>
johnny: hmm, I am just trying to figure out why I am having so many problems setting it up this time around. It was a breeze on my test system
10:18* johnny isn't sure if the deps pull in the desktop environment
10:18
<alkisg>
I don't think so
10:19
So he'll have to install a de...
10:20
<carl>
The server itself has to have a DE installed? I thought that was contained in the chroot
10:20
At this point when I boot up the clients I get to the LDM screen, however I can't login
10:21
<treyh>
alkisg: thank you for the info, 1 of my 6 TS's is spazzing
10:21
<alkisg>
treyh: lucky guess :)
10:23
<treyh>
alkisg: nahh a good guess, it was suck on "applying personal settings" on bootup
10:23
I love vmware, never have to leave my chair to see why servers break lol
10:24
alkisg: you run vmware?
10:25
<johnny>
carl, no.. the chroot contains very little
10:25
only enough to get you to that login screen
10:25hanthana has joined #ltsp
10:26
<carl>
johnny, ah well that may explain a good bit. so a aptitude install ubuntu-desktop should do the trick?
10:26
<johnny>
i think so
10:27
<carl>
alright I shall give it a shot
10:28
<pmatulis>
Gadi1, stgraber: ogra told me you guys have some kind of "output hack" that will help me get a display on a couple of intel-945 based cards
10:29
<epsas>
oooh - dual screens would be nice
10:37
Okay - so I have an ltsp system that I would like to replicate -- are there any pre-rolled tools for installing customized debian systems?
10:39
<alkisg>
treyh: I used to use vmware on windows, now on ubuntu vbox seems easier
10:39
<stgraber>
pmatulis: I actually have to leave soon but I posed an example of a similar hack on ltsp's mailing list recently
10:40
pmatulis: if that's on Ubuntu 9.04, you also have one of these shipped by default that you could use as example
10:40
<pmatulis>
stgraber: yes, on 9.04
10:40
<stgraber>
look in /usr/share/ltsp/screen-session.d for a script called XS20-xserver-intel-desktop-hack
10:40
<pmatulis>
stgraber: nice
10:40
<stgraber>
that's an example of a script removing an LVDS output for a specific card
10:50
<treyh>
alkisg: do you have any solutions for wireless pxe booting?
10:50
<alkisg>
treyh: no, it would need serious messing with the initramfs
10:50
<treyh>
alkisg: yea thats what I figured
10:51
<carl>
johnny, installing the DE did it, I now have booting clients, feel a little silly now thinking it was contained in the chroot

treyh: but what's he trying to *do*?
13:04

<Mip5>
UsUrPeR - I'm wondering about using some of your stations as fat clients - would this be possible?
13:04
<_UsUrPeR_>
mip5: sorry, I missed my invoking the first time. If you refer to me, use the underscores. It will get my attention by flashing the screen and beeping

<treyh>
Gadi1: the screen is blank, and he wanted to "activate" that screen script. He said it didn't work, so I had him try the command to verify he had the same card
13:05* _UsUrPeR_ shuts off the beep
13:05
<Mip5>
_UsUrPeR_ Sorry about that - I'll do that from now on.
13:05
Gadi1 - lol!
13:05
<_UsUrPeR_>
mip5: absolutely. What are you looking for in a fat client?
13:06* Lns kicks Gadi1 from #ltsp - excessive flood (if only I were an op =p)
13:06* CAN-o-SPAM ++ Lns

Well - we've got a dual xeon 3.06 processor machine (about 5 years old) with 4 gb of ram, and the school wants about 30 tc's. I'm wondering about their experience, and whther it would be good to harness some of the power of the clients.

Gadi1: in lts.conf?
13:08zamba_ has joined #ltsp
13:08
<_UsUrPeR_>
prior to ubuntu 8.10, it would make more sense to go the fat client route
13:08
<Gadi1>
treyh: yeah
13:08
if that's your only display
13:08
<treyh>
Gadi1: ty
13:08
<Gadi1>
if you do multihead, you should enumerate each output
13:08
<treyh>
pmatulis_: read what Gadi1 just wrote
13:09
<_UsUrPeR_>
mip5: PM
13:09
<Gadi1>
and then you can manipulate each one's mode's with the corresponding XRANDR_MODE_X
13:09
<treyh>
Gadi1: ty
13:09
<pmatulis_>
treyh: ok, but i have only one output on this client
13:09
<Gadi1>
so, the hack is what is preventing the display?
13:09
is this a laptop?

Gadi1: no, it's not a laptop
13:10
<Gadi1>
is it using LVDS?
13:10
<pmatulis_>
Gadi1: i'm not sure to be honest
13:10
<Gadi1>
prolly not
13:10
<pmatulis_>
Gadi1: how to check?
13:11
<Gadi1>
can you get a shell on the client?
13:11
<treyh>
pmatulis_: remove the script to see if it works
13:11
<pmatulis_>
Gadi1: yes
13:11
Gadi1: also, even after a search, i'm not sure what LVDS is
13:11
<Gadi1>
do you have a GUI set to run on one screen and sshell on the other?
13:11* Gadi1 has so many questions
13:11
<Gadi1>
but they are leading somewhere, I promise
13:11
<pmatulis_>
Gadi1: there is no gui, i don't follow
13:11zamba_ has quit IRC
13:12
<Gadi1>
I mean, do you have:
13:12
SCREEN_07=ldm
13:12
SCREEN_08=shell
13:12
<pmatulis_>
Gadi1: oh, yes, i put that in afterwards
13:12
<Gadi1>
perfect
13:12
boot
13:12
switch to shell
13:12
then do:
13:12
xrandr -display :7 -q

13:13
<Gadi1>
lol
13:13
sorry

(FYI: That script only affects desktops with intel chip and LVDS output.
13:17
LVDS stands for Low Voltage Differential Signalling
13:17
<pmatulis_>
Gadi1: output: Can't open display :7
13:17
<Gadi1>
in EE terms, it is a method of sending two complementary signals for data of opposite sign
13:18
pmatulis_: ah, add this: XAUTHORITY=/var/run/ldm-auth<tab><tab> xrandr -display :7 -q
13:18
where, <tab><tab> means autocomplete
13:18
:)
13:18* pmatulis_ wishes the thin client was right beside him
13:18
<Gadi1>
ah, caap
13:19
you should install ssh in the chroot, then
13:19
:)
13:19
would make your life easier, if devoid of excercise
13:19
<pmatulis_>
got that, thought i needed to be on the console
13:19
<Gadi1>
*exercise
13:19
oh, nah - you can ssh in
13:19
if it is easier
13:19
consoles can be overrated
13:20
<pmatulis_>
there now...
13:20
<Gadi1>
anyway, LVDS signalling results in higher noise immunity, increased sensitivity, at a lower signal overhead
13:21
which makes it great for internal laptop displays
13:21
and a variety of other things

of course, it doubles the pin count and is not compatible with VGA standards that date back some decades

Can't open display :7
13:27* Gadi1 grumbles
13:27
<Gadi1>
ok, let's try a different approach
13:28
scp /var/log/Xrog.7.log to your server and pastebot it
13:28
<pmatulis_>
(i confirmed the SCREN variables with getltspcfg)
13:28

13:35
<pmatulis_>
ok
13:37
<Gadi1>
oh, also, are you using a VGA output or DVI?
13:37
<pmatulis_>
dvi
13:38
<Gadi1>
ah, yeah, with DVI it often helps to request a particular resolution
13:38
also, it seems there are two available outputs - VGA and DVI
13:38
we should probably try being specific
13:39
try: XRANDR_OUTPUT_0 = "VGA --off"
13:39
XRANDR_OUTPUT_1 = "TDMS-1 --auto"
13:39
<pmatulis_>
ok, but there is no vga port
13:40
last boot failed
13:40
<Gadi1>
failed?
13:40
<pmatulis_>
no display (no change)
13:40

ah
13:41Mip5 has quit IRC

thats different than a failed boot
13:41
<pmatulis_>
right
13:41
btw, do quotes matter in lts.conf?
13:41
<Gadi1>
yeah, so lets do this:
13:41
XRANDR_OUTPUT_0 = "VGA --off"

XRANDR_MODE_1 = "1024x768"

13:56
<alkisg>
pmatulis_: does it say "signal out of range" or something?
13:56
<Gadi1>
ah, true - could be the monitor frequencies
13:56
<pmatulis_>
alkisg: one momento
13:57
<alkisg>
(or a led flashing etc)
13:58
<pmatulis_>
alkisg: i don't see any msg appear on the screen
13:58
or flashing led
13:59
i do remember it displaying something before in a little box, but it doesn't show up now
13:59
maybe it does so only once?
13:59
<alkisg>
I think it would worth a try to set specific vert refresh...
14:00
Along with the X_MODE_0=1024x768 that Gadi told you, put these:
14:01
X_HORZSYNC=30.0-70.0
14:01
X_VERTREFRESH=60.0
14:01
I hope these will force 1024x768@60Hz...
14:01
*or maybe horzsync is too low, better put it 30.0-90.0
14:02
<pmatulis_>
specs for the monitor are 31-81 Hz horiz, and 60-76 MHz vertical
14:03
<alkisg>
Ah ok, so put those for the horizontal, but keep the vertical forced to 60
14:03

14:14
the usb sticks cant umount by the user
14:14
<alkisg>
pmatulis_: ok, so I guess it misdetected the vert refresh range.
14:14
<LTSP-questions>
somebody know something about this?
14:14
<alkisg>
LTSP-questions: they're supposed to just pull it out without unmounting :)

14:15
<LTSP-questions>
alsking sure?
14:16
<alkisg>
LTSP-questions: yes, I've heard this from the devs here.
14:16

soo i cant modify this ?
14:17
<alkisg>
pmatulis_: so if you remove everything but the X_* things it'll go fast? Give it a try if you think it will...
14:18
<LTSP-questions>
alkisg: What happen if i pull it out and the Desktop still show the icon of my usb stick???
14:18
<pmatulis_>
alkisg: but the only non X_* thing is XRANDR_DISABLE
14:19
<alkisg>
pmatulis_: I thought you were talking about the [default] stanza
14:19
You mean that the X_* entries made booting slow?
14:19
<pmatulis_>
alkisg: yeah
14:19
<alkisg>
Gadi?
14:19
^^^ ?
14:20
<pmatulis_>
by about double
14:20

I can't think how this would be possible

besides the "Negotiation" thing, i get a whole page of some number (ex: 716 or 734) just the number on many lines

its for me???

treyh_: yeah
14:22
<alkisg>
pmatulis_: ah, I don't know how to set vert refresh with xrandr (and if that's possible), you have to ask Gadi about this
14:23
<treyh_>
pmatulis_: is there a button that says change source?
14:23
<pmatulis_>

14:23

oh cool
14:23

yeah, thanks to you guys :)
14:23

i'm having a problem with the time of my thin clients
15:02Shingoshi has joined #ltsp
15:03
<Scormen>
does anyone has a idea how to set the time of thin clients?
15:03
<Gadi1>
Scormen: TIMEZONE and TIMESERVER params
15:03
<Scormen>
in lts.conf?
15:03
<Gadi1>
yup
15:04
<Scormen>
thans, I'll have a look
15:04japerry has joined #ltsp
15:04
<Gadi1>
thin clients know not how to keep time between boots, as they are stateless
15:04
<Scormen>
are all these parameters in a list on a website somewhere?
15:04
<Gadi1>
so, what you normally get is the hardware time
15:04
(aka BIOS time)
15:05
Scormen: prolly not
15:05
:)
15:05
they may be in lts-paramters.txt
15:05
<Scormen>
hehe :)
15:05
how can we set the hardware time fore the clients then?
15:05
<Gadi1>
well, hardware time is set in the BIOS
15:06
but it will drift over time
15:06
setting with a TIMESERVER should correct the time on boot
15:06
<Scormen>
hmm oke
15:06
<Gadi1>
thanks to einstein, time is relative :P
15:07
<Scormen>
the strange thing is, if I look to the time on the desktop, thats okay
15:07
<Gadi1>
sure
15:07
<Scormen>
but when I look to the time via xterm in a ltsp-localapps, its wrong
15:07
<Gadi1>
the server takes care of desktop time
15:07
the server takes care of its own time
15:07
the client takes care of its own time
15:07
<Scormen>
aha okay
15:07
thats clear
15:08
<Gadi1>
and if the client leaves the station heading west at 9:00AM, the server will meet it in Albequerque around noon
15:08
<treyh_>
lol
15:08
<Scormen>
haha
15:08

Gadi1: but how fast was he going at 10:30am?
15:09

I have an ltsp server running about 20 fat clients. I put Adobe Reader 9x in as a local app so the users could open an fill out pdf online. All other apps running locally can print to the printer connected to the server, but Adobe gives an error stating to chech to see if the printer is connected. Users can print the pdfs with document viewer, but it does not print out what they filled into fields.
15:16
<treyh_>
when you say fat clients
15:16
you mean that they don't pxe boot correct?
15:16Mip5_ has joined #ltsp
15:17
<wkrasko>
Sorry, maybe wrong terminology. They PXE boot, but they run applications locally (on the thin client)
15:17
<treyh_>
gotcha
15:18
wkrasko: you said it right, i just wanted to make sure
15:18
so all the local apps can print, just not adobe 9
15:18
maybe try another pdf reader then?
15:18
i know thats not really the answer but would resolve it for now
15:19
on adobe 9 when you go to file-->print are there any printers listed?

Hey Gang - I'm going to be setting up a new server. It's got 2 zeon 3 GHz cpus, and 4 scsi disks (36 GB, 15k). In the past, I've raided these disks (md0 /, and md1 /home).
15:21
<treyh_>
ok so you can't print from local apps
15:21
wkrasko: are you running ubuntu?
15:23
Mip5: did earlier you say your oldlinux lab was going to die?
15:23
<Mip5>
I've got two q's: 1) is there a better way to set this up given my server hardware, and 2) should I install 9.04? I'd like to be able to have the clients do some of the work if they are powerful enough. THanks in advance
15:23
treyh_ - no, I'm setting up another one for another site
15:24
<treyh_>
Mip5: server setup is fine and yes go with 9.04
15:24
wkrasko: i read somewhere that to get the best support for printing with localapps is to install CUPS in the chroot and update the image
15:25
<Mip5>
treyh_ - thanks. What's the best way to restore from disaster? I can save the data, but would like to be able to bring the server back quickly (since it will be the core of the main lab in the building.

Ok, Ubuntu LTSP server, with HP network printer connected (hp:/net/HP_LaserJet_9000_MFP?ip=192.168.1.84), ltsp clients running OOO, Firefox, Adobe Reader and various others locally, OOO, Firefox, etc print just fine, Document Viewer opens and print pdf's just fine but does not print the values you enter into pdf fields, Adobe Reader gives the following error: "The print process returned error. Please check whether the printer is conn
15:25
ected to the machine". I could just not run Acrobat locally, but then the browser does not find it to open pdfs with.

Hmm, I'll try the cups thing. But then don't I have to go to each thin client and install the printer at each one?
15:26
<treyh_>
no
15:26
don't think so
15:26
but not sure
15:27
even so, if it worked, problem solved
15:28
<Mip5>
wkrasko - when you add a new app for use by your thin clients, do you have to visit each of them, or do you do it inthe chroot?
15:31treyh_ has quit IRC
15:31
<Scormen>
hmm, still the same problem with the time...
15:31
<wkrasko>
In the chroot. But my theory was that the printer is connected to the server's cups. If the thin client now runs it's own copy of cups, does it still see the printer connected to the server?
15:31
Either way, I'll give it a shot.
15:36
<Mip5>
wkrasko - I think doing it in the chroot would be the way to go - though I haven't used localapps yet. For my clients, they can't connect to anything out on the network beyond the ltsp server (I don't have ipv4 forwarding set), so I think your local apps are also connecting to things through the server (and not on their own), in which case you'd want this in the chroot. Again - I haven't worked with localapps yet, so I might be

for typical applications, install it on the server itself. for localapps, install it in the chroot.

hi all
15:44
still problems with the time on the thin clients
15:45
on ltsp.conf I have set: TIMEZONE = "Europe/Brussels"

but still the wrong time

yes

I have no:

wkrasko: you may need to make sure you have cups-bsd in stalled in the chroot
16:01
or whatever it is called
16:01
acrobat uses lpr
16:02
and it seems to only like the cups bsd version
16:02
iirc
16:03
in general, when using localapps, you want to make sure your print queues on the server are shared to the network
16:03
then, they will automagically appear on the localapps
16:04
<wkrasko>
Thanks. I tried just installing cups and hplip locally, but no go. I am installing cups-bsd now.
16:06
<Gadi1>
wkrasko: have you made the queues on the server shared to the network?
16:06
you don't need hplip, since the spooling will be done on the server
16:08
<wkrasko>
Not sure. I have "Publish shared printers connected to this system" checked in settings, and "Shared" checked under printer properties->Policies->State
16:09
<Gadi1>
well, do you see the queues come up in localapps?
16:09CAN-o-SPAM has quit IRC

<wkrasko>
Oh, yeah. In fact anytime someone on another thin client prints, I get the even message popups in the system tray.
16:09
<Gadi1>
if you see the queues and it errors out when printing, then it was because cups-bsd was not installed
16:10
then, you should be good to go
16:10
once cups-bsd is installed
16:17
<wkrasko>
woot, it works! You rock, this is the second time you guys have been VERY helpful. Thanks so much.

now that wouldbe cool

!learn localapps-print as when you wish to print from a localapp. In this case, you need to ensure that the print queues on the server are shared to the network. On Ubuntu, also ensure that both cups and cups-bsd are installed in the chroot
16:31
<ltspbot>
Gadi1: The operation succeeded.

16:39
(as the debian bug report proposes)
16:39
<epsas>
well, maybe my setup is just slow
16:40
it would be great if someone could recompile

i would do it, but i am too busy slacking from work ;)

20:07
treyh: Thanks for the info.
20:09
<treyh>
dark4og: yea 8.10 doesn't work with thecdrom and jump drives
20:10
you have to use 9.04 but you have to make sure ltspfs is installed in the chroot
20:10
do you use ldm or rdesktop?
20:21
<dark4og>
It is installed.. I am using a PXE boot, from a Diskless workstation LTSP Term 1520
20:22

cool

We are now starting to scan in all documents and need to have scanner at the terminal.
20:24

yea
20:24
using 9.04 and ltspfs should work fine
20:24
<dark4og>
That is what started all the USB.. issues..
20:24
<treyh>
you using ldm or rdesktop?

That makes me HAPPY :)

I just boot in with PXE.. No remote
