| 02:28 | <Appiah_> is there a management interface in ltsp-cluster?
| |
| 02:48 | <X-TaZ> Yes

| 02:48 | <X-TaZ> On your control center, Appiah_
| |
| 02:48 | <Appiah_> http right?
| |
| 02:48 | (Have yet to install it)
| |
| 02:48 | <X-TaZ> http://192.168.0.3/ltsp-cluster-control/Admin/admin.php
| |
| 02:49 | <Appiah_> k
| |
| 02:49 | <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
| |
| 02:51 | Bushmills has left #ltsp | |
| 02:51 | <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

| 08:03 | <pmatulis> _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> cliebow: i just told you (?)

| |
| 08:17 | litlebuda has joined #ltsp | |
| 08:19 | <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.
| |
| 08:24 | <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
| |
| 08:27 | K_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
| |
| 08:35 | hanthana has joined #ltsp | |
| 08:35 | <_UsUrPeR_> :/ ogra: any ideas?
| |
| 08:41 | <pmatulis> _UsUrPeR_: i confirmed with getltspcfg that XSERVER = intel

| 08:44 | <K_Wolf> X-TaZ: the ping time is nice (1ms).
| |
| 08:45 | cliebow has joined #ltsp | |
| 08:45 | sep has joined #ltsp | |
| 08:47 | <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
| |
| 08:48 | F-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 :)

| 09:38 | <treyh> 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

| 09:50 | <jammcq> hello friends
| |
| 09:50 | <treyh> jammcq: good morning
| |
| 09:58 | <cliebow> jammcq!!!jammcq!!JAMMCQ
| |
| 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
| |
| 10:03 | litlebuda 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?
| |
| 10:14 | carl 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
| |
| 10:25 | hanthana 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

| 12:57 | <treyh> pmatulis: you tried the vesa driver?
| |

| |

| |
| 13:03 | <rjune> Gadi1: you know much about Oracle?

| 13:03 | <Gadi1> only the Sun part :P

| |
| 13:03 | <Mip5> UsUrPeR - are you around today? I'd like to discuss some diskless workstation options.
| |
| 13:03 | <_UsUrPeR_> mip5: hoy hoy
| |
| 13:04 | <Gadi1> treyh: but what's he trying to *do*?
| |
| 13:04 | :)
| |
| 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
| |
| 13:05 | <Gadi1> _UsUrPeR_: test

| |
| 13:05 | <Gadi1> cool
| |
| 13:05 | :)
| |
| 13:05 | <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 | |
| 13:06 | <Gadi1> treyh: that hack is only useful for multihead, iirc

| |
| 13:06 | <Mip5> 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.

| |
| 13:07 | <treyh> pmatulis: you see that, Gadi said that hack is only for multihead, iirc
| |
| 13:07 | pmatulis: not, no screen problems :)
| |
| 13:07 | <Gadi1> treyh: just use: XRANDR_OUTPUT_0 = "LVDS --auto"

| |
| 13:08 | <pmatulis_> what did i miss?
| |
| 13:08 | <treyh> pmatulis_: sec I'll fill you in
| |
| 13:08 | Gadi1: in lts.conf?
| |
| 13:08 | zamba_ 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?
| |

| 13:10 | zamba has joined #ltsp | |
| 13:10 | <pmatulis_> Gadi1: i havn't removed the script yet
| |
| 13:10 | <Gadi1> is it a laptop?
| |
| 13:10 | <pmatulis_> 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
| |
| 13:11 | zamba_ 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 | * pmatulis_ runs off down a hallway | |
| 13:13 | <Gadi1> lol
| |
| 13:13 | sorry
| |
| 13:16 | (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
| |
| 13:21 | carl has quit IRC | |
| 13:21 | <epsas> i didn't know that
| |
| 13:22 | <Gadi1> of course, it doubles the pin count and is not compatible with VGA standards that date back some decades
| |
| 13:22 | <pmatulis_> Gadi1: i don't have that path in my client
| |
| 13:22 | <Gadi1> hmm
| |
| 13:22 | do you have a /var/log/Xorg.7.log?
| |
| 13:22 | <pmatulis_> /var/run/ldm-xauth-wOKMkRUQF ?
| |
| 13:23 | <Gadi1> ah, that's the one
| |
| 13:23 | sorry

| |
| 13:24 | <Gadi1> try:

| 13:24 | hmm
| |
| 13:24 | do this:
| |
| 13:24 | ls -a /tmp/.X*lock
| |
| 13:25 | <pmatulis_> ls: cannot access /tmp/.X*lock: No such file or directory
| |
| 13:25 | <Gadi1> dont cut/paste
| |
| 13:25 | type it out
| |
| 13:25 | oh, nm
| |
| 13:25 | yeah, so X is not running
| |
| 13:25 | at all
| |

| |
| 13:26 | <pmatulis_> k
| |
| 13:26 | /tmp/.X7-lock
| |
| 13:26 | <Gadi1> ah
| |
| 13:26 | yes, it is
| |
| 13:26 | :)
| |
| 13:26 | ok
| |
| 13:26 | let's check our math
| |
| 13:26 | do this:
| |
| 13:26 | export XAUTHORITY=/var/run/ldm-xauth-wOKMkRUQF
| |
| 13:26 | export DISPLAY=:7
| |
| 13:26 | xrandr -q
| |
| 13:27 | <pmatulis_> 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 | <Gadi1> yeah - not worried about that
| |
| 13:28 | hanthana has quit IRC | |
| 13:28 | <Gadi1> the xorg log will tell all
| |
| 13:31 | <ltsppbot> "pmatulis" pasted "Xorg.7.log" (451 lines) at http://pastebot.ltsp.org/341
| |
| 13:31 | bengoa has joined #ltsp | |
| 13:33 | <Gadi1> interesting...
| |
| 13:35 | seems to have you in 1152x864
| |
| 13:35 | isn't that odd
| |
| 13:35 | try: XRANDR_MODE_0 = "1024x768"
| |
| 13:35 | in lts.conf
| |
| 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 | <Gadi1> ah
| |
| 13:41 | Mip5 has quit IRC | |
| 13:41 | <Gadi1> 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"
| |
| 13:41 | XRANDR_OUTPUT_1 = "TDMS-1 --auto"
| |
| 13:41 | XRANDR_MODE_1 = "1024x768"
| |
| 13:41 | sep has joined #ltsp | |
| 13:41 | <Gadi1> quotes in lts.conf matter when there are spaces in the value
| |
| 13:42 | <pmatulis_> ok
| |
| 13:42 | booting now...

| 13:43 | Egyptian[Home] has quit IRC | |
| 13:43 | japerry has quit IRC | |
| 13:46 | <pmatulis_> nuts
| |
| 13:46 | <Gadi1> really?
| |
| 13:47 | <pmatulis_> yeah, no dice
| |
| 13:47 | <Gadi1> this is 9.04?
| |
| 13:47 | <pmatulis_> yeah
| |
| 13:47 | <Gadi1> well, you can try the old fashioned way:
| |
| 13:47 | use:
| |
| 13:48 | XRANDR_DISABLE = True
| |
| 13:48 | X_MODE_0 = "1024x768"
| |
| 13:51 | <pmatulis_> booting now...
| |
| 13:55 | nuts
| |
| 13:56 | <Gadi1> hmm
| |
| 13:56 | Egyptian[Home] has joined #ltsp | |
| 13:56 | <Gadi1> you've got a tough one
| |
| 13:56 | :)
| |
| 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 | <treyh> pmatulis_: is it a crt or lcd?
| |
| 14:05 | <ltsppbot> "pmatulis" pasted "lts.conf" (56 lines) at http://pastebot.ltsp.org/342
| |
| 14:06 | <pmatulis_> Quanmax is the client we're dealing with
| |
| 14:06 | <alkisg> pmatulis_: better remove ldm_autologin and configure_x
| |
| 14:06 | <pmatulis_> alkisg: ok
| |
| 14:08 | booting now...

| 14:12 | <LTSP-questions> Hello people
| |
| 14:13 | i have some troubles with the usb sticks
| |
| 14:13 | <pmatulis_> it worked
| |
| 14:13 | <LTSP-questions> i try with ltsp in ubuntu 7.04 / 8.04.2 /9.04 and its the same
| |
| 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 :)
| |
| 14:14 | <pmatulis_> alkisg: it takes a long time to get there however
| |
| 14:14 | Scormen has joined #ltsp | |
| 14:15 | <alkisg> pmatulis_: you mean it takes a long time to boot?
| |
| 14:15 | <pmatulis_> alkisg: yeah
| |
| 14:15 | <LTSP-questions> alkisg you want to said that i just pull it out and thats it?
| |
| 14:15 | <alkisg> LTSP-questions: yeah
| |
| 14:15 | Scormen has quit IRC | |
| 14:15 | <LTSP-questions> i dont need to umount?
| |
| 14:15 | <alkisg> no
| |
| 14:15 | pmatulis_: client specs? network speed?
| |
| 14:15 | <pmatulis_> alkisg: i see "Negotiation" and pauses for about 20 seconds. does this a few times
| |
| 14:15 | <LTSP-questions> alsking sure?
| |
| 14:16 | <alkisg> LTSP-questions: yes, I've heard this from the devs here.
| |
| 14:16 | <pmatulis_> alkisg: no, this happened when we started to poke it with lts.conf
| |
| 14:17 | Scormen has joined #ltsp | |
| 14:17 | <LTSP-questions> 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 | <alkisg> I can't think how this would be possible
| |
| 14:20 | <pmatulis_> besides the "Negotiation" thing, i get a whole page of some number (ex: 716 or 734) just the number on many lines
| |
| 14:21 | <LTSP-questions> <alkisg> I can't think how this would be possible
| |
| 14:21 | its for me???
| |
| 14:21 | <alkisg> LTSP-questions: no
| |
| 14:21 | <pmatulis_> alkisg: apparantly we used an old fashioned method to specify the vert rate, is there another way?
| |
| 14:22 | treyh_ has joined #ltsp | |
| 14:22 | <pmatulis_> vert and horiz i mean
| |
| 14:22 | <LTSP-questions> ok
| |
| 14:22 | <treyh_> darn what did i miss
| |
| 14:22 | <alkisg> pmatulis_: the vertical refresh has nothing to do with the boot speed...
| |
| 14:22 | <LTSP-questions> sorry
| |
| 14:22 | and do you read my question?
| |
| 14:22 | <pmatulis_> alkisg: i realize that, separate question
| |
| 14:22 | <treyh_> pmatulis_: is it a crt or lcd?
| |
| 14:22 | treyh has quit IRC | |
| 14:22 | <pmatulis_> lcd is http://www.all-monitors.com/monitors/manufacturers/pos/benq_fp93gx
| |
| 14:22 | <treyh_> does it have a vga and dvi port?
| |
| 14:22 | <pmatulis_> 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_> treyh_: we got it to work btw, just with a low resolution
| |
| 14:23 | <treyh_> oh cool
| |
| 14:23 | <pmatulis_> yeah, thanks to you guys :)
| |
| 14:23 | <alkisg> pmatulis_: you may increase the resolution, just keep the vert refresh low.
| |
| 14:23 | <pmatulis_> thanks everybody
| |
| 14:23 | <treyh_> thanks to Gadi
| |
| 14:23 | <alkisg> Set it to 1280x1024
| |
| 14:24 | <pmatulis_> trying now...
| |
| 14:27 | <LTSP-questions> Then i dont need to umount the usb sticks¿? somebody can said me???
| |
| 14:27 | <epsas> LIBXCB_QUEUE_BUFFER_SIZE=16384
| |
| 14:27 | <cliebow> thanks to Gadi!
| |
| 14:27 | <epsas> is not a fix for the xlib problems in ubuntu/debian
| |
| 14:28 | <treyh_> LTSP-questions: whats your question?
| |
| 14:29 | <LTSP-questions> its about the usb sticks
| |
| 14:29 | <treyh_> LTSP-questions: you want to know if you if you have to umount a usb stick after using it? the answer is no :)
| |
| 14:29 | <LTSP-questions> OK
| |
| 14:29 | thanks
| |
| 14:29 | a lot
| |
| 14:29 | =)
| |
| 14:30 | <pmatulis_> alkisg: k, better resolution. also, i think the slow boot may have been a hiccup (even though it occurred a few times) b/c it booted fine now
| |
| 14:30 | <LTSP-questions> and another question can i modify the enviroment with sabayon for every user ?
| |
| 14:30 | that use the terminal?
| |
| 14:30 | <treyh_> LTSP-questions: whats sabayon?
| |
| 14:30 | <pmatulis_> treyh_: the thing that always crashes?
| |
| 14:30 | <LTSP-questions> http://projects.gnome.org/sabayon/testing.html
| |
| 14:31 | <treyh_> pmatulis_: lol
| |
| 14:31 | <pmatulis_> that's what i hear in many quarters
| |
| 14:31 | happened to me too
| |
| 14:31 | <treyh_> LTSP-questions: yea should work
| |
| 14:32 | <LTSP-questions> ok
| |
| 14:32 | thanks
| |
| 14:32 | and another thing

| 15:00 | <Scormen> hi all
| |
| 15:01 | <pmatulis_> good evening everybody
| |
| 15:01 | pmatulis_ has quit IRC | |
| 15:01 | <Scormen> i'm having a problem with the time of my thin clients
| |
| 15:02 | Shingoshi 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
| |
| 15:04 | japerry 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 | <treyh_> Gadi1: but how fast was he going at 10:30am?
| |
| 15:09 | Gadi1: if they were delayed for 15 minutes due to a cow crossing
| |
| 15:09 | <Gadi1> you'd have to take the first derivitive of space or the second dervitive of space-time

| |
| 15:09 | <Gadi1> thats because the cow needs a timeserver

| 15:11 | <richard_parker_v> Any one else have opinions about doing an in-place upgrade to ubuntu 9.04 on an ltsp server running 8.10? Has ltsp undergone any significant administrative adjustments?

| 15:12 | <wkrasko> Hello all. Im back with another problem, and since you all helped me so easily last time maybe this will be easy too.
| |
| 15:13 | <treyh_> richard_parker_v: I am confident that you shouldn't have too many problems
| |
| 15:13 | backup your customized file just in case and if it does, have a backup jaunty cd ready and your howto guide :)

| 15:15 | <wkrasko> 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?
| |
| 15:16 | Mip5_ 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?
| |
| 15:19 | The_Code has quit IRC | |
| 15:20 | <treyh_> wkrasko: wait a second, can you printer from any other localapp except adobe?

| |
| 15:21 | <Mip5> 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.

| 15:25 | <wkrasko> 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.
| |
| 15:26 | vagrantc has joined #ltsp | |
| 15:26 | <wkrasko> 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?
| |
| 15:31 | treyh_ 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

| 15:38 | <vagrantc> for typical applications, install it on the server itself. for localapps, install it in the chroot.

| 15:44 | <Scormen> hi all
| |
| 15:44 | still problems with the time on the thin clients
| |
| 15:45 | on ltsp.conf I have set: TIMEZONE = "Europe/Brussels"
| |
| 15:45 | vagrantc has quit IRC | |
| 15:45 | <Scormen> but still the wrong time
| |
| 15:48 | richard_parker_v has quit IRC | |
| 15:52 | intelliant has quit IRC | |
| 15:59 | <Gadi1> did you set the TIMESERVER?
| |
| 16:00 | ogra_ has joined #ltsp | |
| 16:00 | <Scormen> yes
| |
| 16:00 | I have no:
| |
| 16:00 | TIMEZONE = "Europe/Brussels"
| |
| 16:00 | TIMESERVER = "91.189.94.4"
| |
| 16:00 | now* :)
| |
| 16:01 | <Gadi1> 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?
| |
| 16:09 | CAN-o-SPAM has quit IRC | |
| 16:09 | <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.

| |
| 16:31 | <Gadi1> !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
