| 02:37 | <no_mind> I have a 64 bit ltsp server and I generated 32 bit client image. When I boot the client with gpxe, I get an error "Failed to connect to NBD server"
| |
| 02:37 | NBD server is running ont he server machine
| |
| 02:41 | <muppis> Try catch does client try to connect and which port. Deafult should be 2000, but sometimes (when arch differs) hits wrong port.
| |
| 02:42 | <no_mind> muppis: I tried connecting to nbd-server from client using this command "nbd-client 192.168.2.4 /dev/nbd0 -persist" . I get an error "nbd0: unknown partition table"
| |
| 02:42 | also
| |
| 02:43 | the gpxe is not autobooting
| |
| 02:43 | I have to manually specify kernel, initrd and boot at gpxe command line
| |
| 02:43 | I am using usb image from rom-o-matic/etherboot
| |
| 02:45 | <muppis> Sounds like you got somehow corrupted imade.
| |
| 02:45 | image..

| 06:31 | <elias_a> Hi - I am writing a short Finnish Howto on Ubuntu LTSP installation. Is there an up-to-date version of hw requirements? I have seen several instances of calculation schemes but I do not know which I should refer to.
| |
| 06:33 | Would this be the best one? https://help.ubuntu.com/community/Installation/SystemRequirements#LTSP%20thin-client%20computers

| 07:23 | <alkisg> That edubuntu wiki is outdated, 48MB clients are not bootable
| |
| 07:28 | <elias_a> alkisg: Yes - I know that - that's why I asked :)

| 09:30 | <Mateus> Good morning from Brazil, can any body help me to run a LTSP with SIP local softphone and local audio?
| |
| 09:33 | ive tried many things without sucess, a can register, make calls, but the sound quality is poor, kinda metalic, ive tried with a livecd on the same pc and the sound work greate
| |
| 09:37 | korcan has joined #ltsp | |
| 09:38 | <muppis> Does software run locallly or server?
| |
| 09:38 | poff has quit IRC | |
| 09:41 | _UsUrPeR_ has joined #ltsp | |
| 09:41 | <Mateus> I tryng locally
| |
| 09:42 | will be 30 stations, then i think the best setup for voip is run softphone locally
| |
| 09:52 | johnny has left #ltsp | |
| 09:56 | <Gadi> Mateus: is the audio out/in using alsa or pulse?
| |
| 09:57 | otavio has joined #ltsp | |
| 09:58 | <Mateus> alsa
| |
| 10:02 | <Gadi> is the out bad or the in bad?
| |
| 10:02 | korcan has quit IRC | |
| 10:03 | <Gadi> ie. (record or playback)?
| |
| 10:03 | korcan has joined #ltsp | |
| 10:03 | <Mateus> both, only in the softphone, others prograns running on server the sounds perfect
| |
| 10:04 | <Gadi> can you set the softphone to use pulse?
| |
| 10:05 | <Mateus> pulse works with program running locally?
| |
| 10:05 | <Gadi> it should, I believe
| |
| 10:06 | <Mateus> ok, I'll try after my lunch, thanks a lot for your attention
| |
| 10:06 | <Gadi> alternatively, you can try installing pulseaudio-utils in the chroot and run: pasuspender -- /path/to/softphone
| |
| 10:06 | <Mateus> hm ok
| |
| 10:06 | <Gadi> actually, I think someone else here with a softphone wound up doing that
| |
| 10:07 | <Mateus> good, thanks again
| |
| 10:07 | bye, i'll come back later...

| 11:19 | <sidartha> Is there anyone around who can help me figure out why two of my clients cannot gogin?
| |
| 11:20 | Login. Its only two of my twelve machines.
| |
| 11:20 | <Kyle__> sidartha: Are you sure they're booting all the way? Can you ssh to them, or login using a local account?
| |
| 11:21 | vagrantc has joined #ltsp | |
| 11:21 | <sidartha> I get to the LDM LoGIN SCreen , But no matter what user I use, it goes back to the login screen
| |
| 11:21 | <alkisg> sidartha: it might be a compiz problem, do you see an entry in /var/log/auth.log ?
| |
| 11:28 | <sidartha> i dont see anything about compiz. Here is a section of the log
| |
| 11:28 | http://pastebin.com/tbVMMA7J
| |
| 11:31 | Faithful has quit IRC | |
| 11:33 | <alkisg> sidartha: is this from a problematic client? "Sep 13 12:27:52 ubuntuARTROOM-LTSP sshd[813]: Accepted password for blue from 192.168.0.30 port 35267 ssh2"
| |
| 11:33 | I mean, if it accepts the password, then it's a session problem, possibly compiz
| |
| 11:33 | !compiz
| |
| 11:33 | <ltspbot> alkisg: "compiz" :: if compiz is giving you problems, one way to disable it for all users is: sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type string --set /desktop/gnome/session/required_components/windowmanager metacity
| |
| 11:35 | <sidartha> ill try that
| |
| 11:38 | that did it.. Thanks again
| |
| 11:43 | otavio has quit IRC | |
| 11:43 | <sidartha> alright I have another problem.
| |
| 11:43 | jhutchins_lt has joined #ltsp | |
| 11:44 | <sidartha> I installed Chromium in chroot and have it running as a local app, however whenever I reboot the machine I have to set it up as if I opened it again for the first time.
| |
| 11:44 | Its not saving its session
| |
| 11:47 | <alkisg> AFAIK chromium doesn't work with sshfs (the default with localapps), it needs nfs
| |
| 11:50 | otavio has joined #ltsp | |
| 11:50 | <sidartha> I changed include this string in LTS.CONF [NFS_HOME=/home] Do I have to add another directory for it to save its session?
| |
| 11:52 | <alkisg> No, but did you export /home from your server?
| |
| 11:52 | If you didn't, then it still uses sshfs...
| |
| 11:52 | pmatulis has joined #ltsp | |
| 11:52 | <alkisg> (and, you didn't add the square brackets there, did you?)
| |
| 11:54 | <sidartha> no square brackets. How do I export /home?
| |
| 11:57 | pmatulis has quit IRC | |
| 11:57 | pmatulis has joined #ltsp | |
| 11:58 | <Kyle__> sidartha: Be careful if you use nfs off of an ubuntu server: their rcp.stad is buggy.
| |
| 11:58 | bobby_C has joined #ltsp | |
| 11:59 | <sidartha> Sounds Like I should just stick with Firefox? Know of a way to sync extensions, bookmarks?
| |
| 12:00 | <alkisg> sudo -i
| |
| 12:00 | echo '/home *(rw,sync,no_subtree_check)' >> /etc/exports
| |
| 12:00 | exportfs -ra
| |
| 12:01 | That exports /home...
| |
| 12:01 | And I'm also using NFS_HOME_OPTIONS=defaults,nolock in lts.conf to bypass that statd problem
| |
| 12:02 | (nolock ==> users shouldn't open the same file for writing simultaneously)
| |
| 12:02 | (it's only a work around, and not a good one, but it works for me)
| |
| 12:03 | Ah, and sudo apt-get install nfs-kernel-server
| |
| 12:03 | <sidartha> alkisg: the reason I am using chromium is because of the sync ability. Do you think I should stay with firefox, and just install addons individualy?
| |
| 12:03 | <alkisg> How much ram on your clients?
| |
| 12:04 | <sidartha> 512
| |
| 12:04 | <alkisg> Both would do, it's a personal choice...
| |
| 12:04 | <sidartha> ok Thanks
| |
| 12:04 | mistik1 has joined #ltsp | |
| 12:07 | Gadi has left #ltsp | |
| 12:18 | <sidartha> alkisg: I expoted /home and added NFS_HOME_OPTIONS=defaults, but chromium is still not saving sessions, How can I chech if NFS /home is set up?
| |
| 12:19 | <alkisg> !localxterm
| |
| 12:19 | <ltspbot> alkisg: "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.
| |
| 12:19 | <alkisg> sidartha: on a localxterm, run `mounts` and see if /home is mounted with nfs
| |
| 12:19 | Erm, mount, not mounts
| |
| 12:22 | <sidartha> I dont see /home listed
| |
| 12:23 | <alkisg> So it's not mounted with nfs
| |
| 12:24 | $ cat /var/lib/nfs/etab
| |
| 12:24 | /home *(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534)
| |
| 12:25 | This tells you if it's exported on the server
| |
| 12:26 | <sidartha> I think I made a duplicat /home export? How can I delete one of them.
| |
| 12:27 | it is exported to the server
| |
| 12:27 | <alkisg> sudo gedit /etc/exports
| |
| 12:27 | fix it, and run sudo exportfs -ra
| |
| 12:29 | otavio has quit IRC | |
| 12:29 | otavio has joined #ltsp | |
| 12:30 | otavio has joined #ltsp | |
| 12:33 | <sidartha> ok I fixed it and ran sudo exportfs -ra, and it says /home *(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534)
| |
| 12:33 | But It stiil not mounting on local
| |
| 12:34 | <alkisg> Can you paste your lts.conf? Also, is this Lucid?
| |
| 12:37 | <sidartha> http://pastebin.com/spam.php?i=iaWdrXC0 This is Lucid
| |
| 12:39 | <alkisg> What does `status statd` tell you on the server?
| |
| 12:39 | Also, remove /home from LOCAL_APPS_EXTRAMOUNTS
| |
| 12:40 | (and, until you get it right, you may want to try: NFS_HOME_OPTIONS=defaults,nolock)
| |
| 12:41 | (a client reboot is needed - logoff won't do it)
| |
| 12:42 | <sidartha> statd start/running, process 3634
| |
| 12:44 | and still not mounting
| |
| 12:44 | made lts.conf changes
| |
| 12:44 | <alkisg> Try getting a local root screen on the client and mounting /home somewhere else manually:
| |
| 12:45 | In lts.conf, add:
| |
| 12:45 | SCREEN_02=shell
| |
| 12:45 | SCREEN_07=ldm
| |
| 12:45 | Reboot client, and at ldm press alt+ctrl+f2, you'll get a local root console
| |
| 12:45 | mkdir /tmp/home
| |
| 12:45 | mount -t nfs server:/home /tmp/home
| |
| 12:51 | <sidartha> wron fs type....error
| |
| 12:51 | wrong fs type
| |
| 12:53 | <vagrantc> is nfs-common installed in the chroot?
| |
| 12:53 | <sidartha> no
| |
| 12:54 | installing it know
| |
| 12:54 | now
| |
| 12:55 | <alkisg> (remember to run ltsp-update-image)
| |
| 12:57 | <vagrantc> alkisg: nfs-common is needed, yes?
| |
| 12:58 | <alkisg> On my notes in https://help.ubuntu.com/community/UbuntuLTSP/FatClients I have nfs-client, let me see in my sch-scripts code...
| |
| 13:00 | You're right, nfs-client is obsolete, I should change that to nfs-common, thanks :)
| |
| 13:11 | <sidartha> bingo that worked.. Thank Both Of you.

| 15:12 | <cole2> Hi, I was here a few hours ago asking about hp tf5700 video driver. The card states (From lspci) ATI Rage LX, the spec sheet says ati rage lx. its an 8mb card. I dont know what driver i am currently using but i have managed to get better resoultion by copying the entire mode line from one I found elsewhere. I dont understand the mode line so i cannot tell if it is the good thing to do or not.
| |
| 15:13 | <thunsucker> anyone have a link to modify the rdesktop screens script to modify the refresh time
| |
| 15:14 | <alkisg> cole2: a mode line works, but XRANDR_MODE_0 doesn't?
| |
| 15:16 | <cole2> Through all my Reading I have never seen XRANDR_MODE_0 how do I use this?
| |
| 15:16 | <alkisg> !lts.conf
| |
| 15:16 | <ltspbot> alkisg: "lts.conf" :: http://manpages.ubuntu.com/lts.conf
| |
| 15:17 | <alkisg> See the docs :)
| |
| 15:17 | XRANDR_MODE_0=1024x768
| |
| 15:22 | Could someone tell me the correct english word for this? Suppose that a school has 60 first-grade students, and they are divided into 3 groups of 20, and each group has its own classroom. What are those groups called? Classes?
| |
| 15:23 | <jammcq> sounds good to me
| |
| 15:23 | <alkisg> Thanks!
| |
| 15:24 | <thunsucker> alkisg: have you ever heard anything the refresh rate of the rdesktop script?
| |
| 15:24 | <alkisg> What refresh rate? Of the screen, e.g. 60Hz?
| |
| 15:25 | <cole2> Thanks, I dont know why i have never seen the whole section before. I will do some reading and try it out a little later on.
| |
| 15:32 | paal- has joined #ltsp | |
| 15:49 | <thunsucker> alkisg: no the rdesktop client waits a few minutes then "refreshes"
| |
| 15:49 | <alkisg> thunsucker: that's not related to the script
| |
| 15:49 | The windows server closes the connection because it assumes it's idle
| |
| 15:49 | You can change that in the windows server settings. I found the setting once, but never again :D
| |
| 15:50 | ....so people here make a loop in the rdesktop script so that X doesn't die on each disconnection...
| |
| 15:50 | <thunsucker> gotcha
| |
| 15:51 | logonui.exe is putting a heavy load on our ts server cpu's
| |
| 15:51 | so we're looking at alternatives
