| 02:01 | <gnunux> hi
| |
| 02:05 | <elias_a> alkisg: thanks for keeping up the pressure on Adobe Flash player and FP-40 bug :)
| |
| 02:05 | <alkisg> elias_a: are you still affected by it?
| |
| 02:06 | It's pretty much ok for me now, except for the accented characters... (which are important...)
| |
| 02:06 | <elias_a> alkisg: Not to my knowledge....
| |
| 02:06 | But I have not done a thorough test.
| |
| 02:07 | <alkisg> I do hope that it gets out of beta in time for lucid ... :-/
| |
| 02:07 | <elias_a> We have some probs with some services. We used a workaround in OpenMeetings and now the workaround causes problems when the bug is fixed :(

| 03:31 | <nubae> alkisg: ping
| |
| 03:32 | <alkisg> hi nubae
| |
| 03:32 | <nubae> good morning...
| |
| 03:32 | I'm just looking through my config files again to see whats up with my nbd connection refused errors
| |
| 03:33 | I noticed that my dhcpd.conf has /ltsp/i386/nbi.img and not /opt/ltsp/i386/nbi.img... is that correct?
| |
| 03:33 | <alkisg> That's relative to the tftpbootdir
| |
| 03:34 | /var/lib/tftpboot - /ltsp/i386/nbd.img
| |
| 03:34 | <nubae> hmm, yeah so its correct
| |
| 03:34 | I've got my router as 192.168.1.1 which is my internet router and ltsp/dhcp server as 192.168.1.128
| |
| 03:35 | maybe there is an issue of being on the same subnet?
| |
| 03:36 | <alkisg> You said yesterday that you succeeded in manually calling nbd-client
| |
| 03:36 | So I guess it's a race problem
| |
| 03:36 | <nubae> yeah I did
| |
| 03:36 | <alkisg> Just change ltsp_nbd so that it has a sleep there, or so that it calls nbd-client twice if it fails the first time
| |
| 03:37 | Are you using the stock ltsp or some newer version from a repo?
| |
| 03:37 | <nubae> nope its stock karmic
| |
| 03:38 | <alkisg> Yup then try with a sleep or calling it twice
| |
| 03:38 | <nubae> ltsp_nbd in hooks or scripts dir?
| |
| 03:38 | <alkisg> scripts
| |
| 03:39 | <nubae> sleep at the top?
| |
| 03:40 | <alkisg> right before the nbd-client call
| |
| 03:40 | then update-initramfs -u at the chroot, and ltsp-update-kernels
| |
| 03:40 | put a sleep 5 just to be safe...
| |
| 03:41 | Egyptian[Home] has quit IRC | |
| 03:41 | pts_ has quit IRC | |
| 03:45 | pts_ has joined #ltsp | |
| 03:45 | <nubae> yeah that didnt work, seems like its looking for nbd-server at 192.168.1.1
| |
| 03:47 | I've got nextserver defined as 192.168.1.128 in dhcpd.conf, but client seems to ignore that and tries to connect to 192.168.1.1
| |
| 03:47 | doing a manual connect to 192.168.1.128 from the client works though
| |
| 03:47 | <alkisg> nubae: did you try nbdroot=1.2.3.4:2000 like I told you yesterday?
| |
| 03:47 | (i.e. nbdroot=192.168.1.128:2000)
| |
| 03:48 | <nubae> from the client, yes
| |
| 03:48 | <alkisg> No, from pxelinux.cfg/default
| |
| 03:48 | <nubae> ah no, havent tried that
| |
| 03:48 | <alkisg> Try to put it as a kernel parameter there
| |
| 03:51 | <nubae> same problem, at the end it says eth0 configured at 192.168.1.128 192.168.1.1 192.168.1.1 255.255.255.0, does that sound right?
| |
| 03:56 | when restarting the nbd server I get:
| |
| 03:56 | Restarting Network Block Device server: Stopping Network Block Device server: nbd-server.
| |
| 03:56 | ** (process:16127): WARNING **: Could not parse config file: Could not open config file.
| |
| 03:56 | <alkisg> It sounds like you have the dhcp server of the router open :)
| |
| 03:57 | But nbdroot should solve that problem...
| |
| 03:57 | <nubae> I dont, I guarantee it
| |
| 03:57 | <alkisg> Can you pastebin your dhcpd.conf ?
| |
| 03:59 | <nubae> http://pastebin.be/23794
| |
| 03:59 | is it normal though, the nbd cannot parse config file?
| |
| 04:00 | <alkisg> Yes, there's no config file
| |
| 04:00 | <nubae> ok
| |
| 04:00 | <alkisg> nubae: can you put break=mount in pxelinux.cfg/default,
| |
| 04:00 | ah no
| |
| 04:01 | You don't need that, you already get a busybox
| |
| 04:01 | So, what do you see with `cat /tmp/net-eth0.conf` and with `cat /tmp/dhcp-info-i-don't-remember-the-exact-name` ?
| |
| 04:01 | <nubae> I'm putting the sleep further up cause it doesnt seem to sleep properly
| |
| 04:01 | net-eth0 doesnt exist
| |
| 04:01 | neither does dhcp-indo
| |
| 04:04 | <alkisg> nubae: try with break=mount
| |
| 04:05 | <nubae> just did
| |
| 04:05 | <alkisg> then, cat /tmp/net-eth0.conf && cat /tmp/dhcp-info.conf
| |
| 04:05 | <nubae> no difference
| |
| 04:05 | <alkisg> What, they don't exist with break=mount?!
| |
| 04:05 | That's too weird
| |
| 04:05 | <nubae> nope
| |
| 04:05 | <alkisg> Do you have write access to /tmp ?
| |
| 04:06 | <nubae> yeah directory is 777
| |
| 04:06 | owned by root though
| |
| 04:07 | <alkisg> Something's really wrong with the mint initscripts :)
| |
| 04:07 | <nubae> i guess... will have to use Ubuntu proper I guess
| |
| 04:09 | can I create an ubuntu server VM on the mint machine to do the ltsp stuff?

| 04:23 | bobby_C has joined #ltsp | |
| 04:25 | Egyptian[Home] has joined #ltsp | |
| 04:36 | <nubae> alkisg: any idea if I can use a VM as a server instead of reinstalling with Ubuntu?
| |
| 04:36 | klausade has joined #ltsp | |
| 04:36 | <alkisg> nubae: sure
| |
| 04:36 | <nubae> Have u ever set it up that way?
| |
| 04:36 | <alkisg> Yup
| |
| 04:36 | But if you're around in the afternoon, I may be able to help more with your current problem
| |
| 04:37 | <nubae> any noticable lag or speed or something?
| |
| 04:37 | <alkisg> Since you used --dist=karmic, you shouldn't be having anything mint-specific in your chroot
| |
| 04:37 | <nubae> alkisg: well I'll leave it as it is then, but this could be a bit of nasty problem probably buried in the init scripts
| |
| 04:37 | <alkisg> So maybe your network is your problem, or a bug in the upstream scripts, and not mint...
| |
| 04:38 | nubae: can you try putting stgraber's ppa (or my ppa) in both your server's and chroot's sources?
| |
| 04:38 | <nubae> sure... I could also try and build a different dist in the chroot
| |
| 04:38 | <alkisg> That way, if there's a bug there, and it was solved between karmic <=> lucid, we won't have to deal with it again...
| |
| 04:38 | <nubae> ok
| |
| 04:38 | <alkisg> No need, karmic is fine
| |
| 04:38 | sudo add-apt-repository ppa:stgraber
| |
| 04:38 | apt-get update / dist-upgrade
| |
| 04:38 | both in server + chroot
| |
| 04:39 | <nubae> I've got a dns problem in the chroot it seems
| |
| 04:40 | cant resolve host osiris (my server)
| |
| 04:40 | maybe I have to manually define it in the chroot?
| |
| 04:41 | <alkisg> cp /etc/resolv.conf /opt/ltsp/i386/etc/resolv.conf
| |
| 04:42 | Also don't use sudo in the chroot
| |
| 04:42 | <nubae> yeah its already thesame
| |
| 04:42 | <alkisg> You're already root there
| |
| 04:42 | <nubae> I added osiris to hosts
| |
| 04:42 | that should fix it
| |
| 04:43 | add-apt-repository command not found in chroot
| |
| 04:43 | ogra_ has joined #ltsp | |
| 04:43 | Selveste1 has quit IRC | |
| 04:43 | <nubae> wait that makes no sense
| |
| 04:44 | Selveste1 has joined #ltsp | |
| 04:44 | ogra has quit IRC | |
| 04:45 | <nubae> hmm, alkisg, ideas? command not found, what do I need to install
| |
| 04:45 | <alkisg> nubae: wget http://ts.sch.gr/repo/add-ppa.sh -O /tmp/add-ppa.sh
| |
| 04:45 | sh /tmp/add-ppa.sh stgraber
| |
| 04:45 | That should do it...
| |
| 04:46 | (I got this for other teachers here - so don't pay attention to any greek messages :))
| |
| 04:46 | <nubae> ok so add-ppa is the command?
| |
| 04:47 | right ok done
| |
| 04:47 | love the cyrillic :-)
| |
| 04:48 | <alkisg> Nah, Greek isn't cyrillic
| |
| 04:49 | ogra_ is now known as ogra | |
| 04:49 | ogra has joined #ltsp | |
| 04:49 | <nubae> oh it isnt?
| |
| 04:49 | * nubae feels silly now | |
| 04:49 | <alkisg> Some Greek priests invented the cyrillic alphabet when they tought christianism to russians etc
| |
| 04:49 | But the greek alphabet was there eons ago..
| |
| 04:49 | <nubae> I'm European.. I shouldn't make American mistakes :-)
| |
| 04:49 | <alkisg> Heh :D
| |
| 04:50 | <nubae> ok, so rebuild image and update?
| |
| 04:52 | <alkisg> Also update-initramfs -u
| |
| 04:52 | (in the chroot)
| |
| 04:52 | <nubae> exit
| |
| 04:52 | oops
| |
| 04:52 | heh
| |
| 04:53 | hmm dist=karmic doesnt work now
| |
| 04:54 | ah never mind, forgot to delete /opt/ltsp/i386
| |
| 04:55 | wait, its not using the ppa now is it?
| |
| 04:55 | F-GT has quit IRC | |
| 04:58 | <nubae> alkisg: ?
| |
| 04:58 | <alkisg> nubae: why did you delete the chroot?
| |
| 04:58 | <nubae> yeah
| |
| 04:58 | <alkisg> You just had to update it...
| |
| 04:58 | <nubae> I'm just worried its not using the ppa
| |
| 04:59 | oh ok
| |
| 04:59 | well its building now, but I did --dist=karmic
| |
| 04:59 | will that use the ppa?
| |
| 04:59 | <alkisg> Nope
| |
| 04:59 | You'd have to use --extra-mirror for this
| |
| 04:59 | Just add the ppa in the chroot after it finishes building
| |
| 05:00 | (with the command I pasted above)
| |
| 05:00 | <nubae> oh, shit.. right....
| |
| 05:00 | :-)
| |

| 07:06 | <anivair> quick question for the room
| |
| 07:06 | I'm currently running softphones on ltsp as localapps and using pulse audio suppression.
| |
| 07:07 | which works great until the phone loses focus and then they get static because p ulse doesn't know what's going on, but it's being used for other apps
| |
| 07:07 | since I don't need sound for anything but the phones, is there a way to run the whole desktop session with pasuppression?
| |
| 07:07 | or to set the users up to just wrap everything in it and skip pulse alltogether?

| 08:07 | Gadi has joined #ltsp | |
| 08:13 | <Gadi> anivair: set SOUND_DAEMON to a bogus value, and pulse will not run at all on the client
| |
| 08:13 | anivair: then, you will be good to go
| |
| 08:14 | <anivair> where is that value set?
| |
| 08:15 | <Gadi> in lts.conf
| |
| 08:15 | <anivair> thanks. I'll give that a shot
| |
| 08:15 | <Gadi> so, you can add: SOUND_DAEMON=bubba
| |
| 08:15 | :)
| |
| 08:16 | you will likely get a warning saying that it cannot start bubba
| |
| 08:16 | <anivair> that'll be amusing if someone else inherits my job in the future
| |
| 08:16 | <Gadi> but, other than that, you'll be ok
| |
| 08:16 | mgariepy has joined #ltsp | |
| 08:16 | <Gadi> gotta have fun with it
| |
| 08:16 | its a moral imperative
| |
| 08:17 | <anivair> (that is how you m otivate someone)
| |
| 08:17 | now I just cross my fingers that nobody comes out with a bubbe sound daemon
| |
| 08:17 | <Gadi> (of course, you will need to take out pasuspender and just call twinkle directly once you do this, as pasuspender will have nothing to suspend)
| |
| 08:17 | <anivair> right
| |
| 08:17 | I'll play with it this weekend
| |
| 08:18 | I'm also going ot write a little script that kills twinkle and removes twinkle.lck if it exists before it starts the program, because I'm getting a LOT of in stances where twinkle shuts down funny and gets hung up at start
| |
| 08:18 | * Gadi makes mental note that we should actually just make "False" one of the values for SOUND_DAEMON | |
| 08:21 | <anivair> heh. true
| |
| 08:21 | <mgariepy> morning

| 09:19 | <sbalneav> Morning all

| 09:19 | klausade has joined #ltsp | |
| 09:21 | <highvoltage> morning sbalneavness
| |
| 09:25 | klausade has quit IRC | |
| 09:26 | <ftherese> morning... is there a lts.conf variable to set the timezone?
| |
| 09:27 | <sbalneav> !docs
| |
| 09:27 | <ltspbot`> sbalneav: "docs" :: For the most current documentation, see https://sourceforge.net/apps/mediawiki/ltsp/index.php?title=Ltsp_LtspDocumentationUpstream
| |
| 09:27 | <sbalneav> ftherese: yes there is.
| |
| 09:27 | thunsucker has joined #ltsp | |
| 09:27 | <ftherese> I am reading the LTSPManual... so it is just in another location?
| |
| 09:28 | I just downloaded that file and was reading it
| |
| 09:29 | <sbalneav> Chapter 10
| |
| 09:29 | page 34
| |
| 09:29 | General Thin CLient Parameters
| |
| 09:29 | TIMEZONE
| |
| 09:29 | <ftherese> ok got it sorry...
| |
| 09:29 | do you know what format it should be in?
| |
| 09:30 | <sbalneav> I would expect the normal timezone format
| |
| 09:31 | <ftherese> so I could try UTC+0100
| |
| 09:31 | <sbalneav> in the code it copies:
| |
| 09:32 | cp /usr/share/zoneinfo/$TIMEZONE /etc/localtime
| |
| 09:32 | <ftherese> maybe it doesn't like the +0100, because it is off by an hour
| |
| 09:32 | but that is what `date` looks like
| |
| 09:32 | <sbalneav> so I would expect you'd need to do the normal America/Winnipeg format
| |
| 09:33 | where are you?
| |
| 09:33 | <ogra> what ? there is no Canada in there ?
| |
| 09:33 | <sbalneav> ogra: No, we don't rate
| |
| 09:33 | <ogra> booo
| |
| 09:33 | * ftherese looking at /usr/share/zoneinfo | |
| 09:33 | <ftherese> France
| |
| 09:33 | Paris
| |
| 09:34 | well... not paris, but paris timezone
| |
| 09:34 | <sbalneav> so Europe/Paris
| |
| 09:34 | <ogra> Europe/Paris then
| |
| 09:34 | <sbalneav> TIMEZONE=Europe/Paris
| |
| 09:34 | <ftherese> ok thanks
| |
| 09:35 | also, I was wondering about the guest login feature - does it look for a guest account?
| |
| 09:36 | how does it work?
| |
| 09:36 | Faithful has quit IRC | |
| 09:37 | <ftherese> I just tried enabling LDM_GUESTLOGIN or whatever it is, it made a button, but when you push it the computer just thrashes around for a while until it finally returns to the LDM login screen

| 09:37 | <ftherese> do you have to create a special account?

| 09:38 | <thunsucker> ftherese: you running ubuntu 8.04 ?

| |
| 09:40 | I am reading something about udev/rules.d/50-ltspfsd.rules
| |
| 09:40 | <thunsucker> ftherese: will you pastebin your lts.conf section with LDM_GUESTLOGIN in it

| 09:47 | thunsucker has quit IRC | |
| 09:48 | <thunsucker_> ftherese: i don't see anything wrong with your lts.conf
| |
| 09:48 | i'm researching it now
| |
| 09:49 | <ftherese> I think there must needs be a guest account installed on the server or something, but I don't know what it should look like - I really don't even know how it works or if it works
| |
| 09:50 | <thunsucker_> ftherese: is gdm-guest-session installed?
| |
| 09:51 | Faithful has joined #ltsp | |
| 09:51 | <ftherese> on the server or the client?
| |
| 09:51 | <thunsucker_> try the server
| |
| 09:51 | * ftherese is also looking at https://help.ubuntu.com/community/UbuntuLTSP/AutoLoginFeatures | |
| 09:51 | <thunsucker_> dpkg -s gdm-guest-session
| |
| 09:52 | <ftherese> yeah... that is installed
| |
| 09:52 | I am going to try adding LDM_ALLOW_GUEST
| |
| 09:52 | to see if that works
| |
| 09:54 | alkisg has joined #ltsp | |
| 09:55 | kusznir has joined #ltsp | |
| 09:58 | <ftherese> that didn't do it... timezone is still wrong too - thunsucker_
| |
| 10:00 | <thunsucker_> ftherese: i know this is generic but i always ask, have you updated your server and the chroot?
| |
| 10:00 | sudo apt-get update && apt-get dist-upgrade on both?
| |
| 10:03 | <ftherese> I just did this morning... I can make sure there are no packages though
| |
| 10:03 | (four different servers to check...)
| |
| 10:04 | looks like the next kernel version just came out
| |
| 10:05 | it will take a while
| |
| 10:05 | <alkisg> ftherese: you need LDM_USERNAME and LDM_PASSWORD in lts.conf for the guest feature to work
| |
| 10:05 | If you don't specify them, they default to the client hostname
| |
| 10:05 | I.e. ltsp123/ltsp123 - so you'd need a user account with that name and password
| |
| 10:06 | <ftherese> ah!
| |
| 10:06 | bingo
| |
| 10:06 | thank you alkisg
| |
| 10:06 | <alkisg> ftherese: isn't that in the docs?
| |
| 10:06 | !docs
| |
| 10:06 | <ltspbot`> alkisg: "docs" :: For the most current documentation, see https://sourceforge.net/apps/mediawiki/ltsp/index.php?title=Ltsp_LtspDocumentationUpstream
| |
| 10:06 | <ftherese> I didn't see it
| |
| 10:06 | <alkisg> !lts.conf
| |
| 10:06 | <ltspbot`> alkisg: "lts.conf" :: http://manpages.ubuntu.com/lts.conf
| |
| 10:06 | <ftherese> maybe it is in the lts.conf man file
| |
| 10:06 | <alkisg> Yeah, it's there... http://manpages.ubuntu.com/manpages/lucid/en/man5/lts.conf.5.html#toptoc12
| |
| 10:07 | <ftherese> the only thing in the LTSPManual is the LDM_GUESTLOGIN value
| |
| 10:07 | *var
| |
| 10:08 | is there any way to cut down on the number of home dirs?
| |
| 10:08 | <alkisg> ftherese, it's also in the manual, in 21.4 Auto login features
| |
| 10:08 | What do you mean by that?
| |
| 10:08 | <johnny> ftherese, no..
| |
| 10:08 | <alkisg> Have 3-4 users share the same home dir?
| |
| 10:08 | <johnny> programs don't like running alongside other programs
| |
| 10:09 | err other instances of the same program that is
| |
| 10:09 | firefox is especially bad at it
| |
| 10:10 | hacky.. but neat ..
| |
| 10:10 | http://chris-lamb.co.uk/2008/01/24/can-you-get-cp-to-give-a-progress-bar-like-wget/
| |
| 10:11 | <ftherese> I know, but what I don't like is creating 100 guest home dirs to be routinely filled with firefox cache and waste space on the server
| |
| 10:11 | and whatever other temporary files it happens to create
| |
| 10:11 | or the user happens to download or copy during their brief stay
| |
| 10:12 | maybe a script at the end that just completely erased the home directory...
| |
| 10:12 | <johnny> that's what i do
| |
| 10:12 | once a day
| |
| 10:12 | <alkisg> ftherese: you need 100 guest accounts for 100 PCs? You could make them under /home/guests/guest88, and also make a script that erases everything at logon...
| |
| 10:12 | <johnny> not completely erase their /home.. just the contents of ~/
| |
| 10:12 | <ftherese> right
| |
| 10:13 | I would just assume they use the ltspXXX user/pass and not have to fill out the lts.conf file with mac addresses
| |
| 10:13 | etc
| |
| 10:14 | <johnny> http://pastie.org/853678
| |
| 10:14 | that's what i use
| |
| 10:14 | Selveste1_ has quit IRC | |
| 10:14 | <ftherese> so... in the $CHROOT/usr/share/ldm/rc.d/ make a S or K script?
| |
| 10:15 | <johnny> i do it on the server ftherese
| |
| 10:15 | cron the sript at night
| |
| 10:17 | <ftherese> ah... that would be simpler than rebuilding the thinclients
| |
| 10:18 | <alkisg> Except that the next guest would see what the previous guest visited on firefox etc
| |
| 10:18 | <johnny> alkisg, at that point you'd set it to go in private mode
| |
| 10:18 | doesn't the firefox in karmic ship with firefox that can do private mode?
| |
| 10:18 | <alkisg> johnny: it's not only firefox...
| |
| 10:18 | <johnny> nobody ever logs out of terminals at my store
| |
| 10:18 | they just stay on
| |
| 10:18 | so even such a script would never work
| |
| 10:18 | since nobody logs out
| |
| 10:19 | <alkisg> And you clear their homes while logged on?
| |
| 10:19 | <johnny> no
| |
| 10:19 | at night only
| |
| 10:19 | after close
| |
| 10:19 | <alkisg> I'd put a sign somewhere that logoff erases everything, so those concerned with privacy could just logoff
| |
| 10:19 | <johnny> ftherese, if you think your users will actually log out.. then such a thing is probably wanted ..
| |
| 10:20 | staffencasa has joined #ltsp | |
| 10:20 | <johnny> alkisg, i would use a script if you wrote it..
| |
| 10:20 | only problem now.
| |
| 10:20 | is having to actually put such a script in the chroot
| |
| 10:20 | <alkisg> Heh :)
| |
| 10:20 | I don't think it's needed in the chroot
| |
| 10:20 | <johnny> i hate having to remember mods i've done to the chroot :)
| |
| 10:20 | ah.. it also uses accounts on the server for other things..
| |
| 10:21 | <alkisg> ...but I don't know offhand where I'd put it, to ensure that it's the first thing to run
| |
| 10:21 | If '
| |
| 10:21 | if username==guest*, then erase everything
| |
| 10:21 | That shouldn't bother him with other accounts
| |
| 10:22 | <johnny> on login is probably better
| |
| 10:22 | as people often hard power off machines
| |
| 10:22 | <ftherese> I have a script that builds a new chroot from scratch and adds everything for localapps firefox, chromium, openoffice etc., with the localdev support etc...
| |
| 10:23 | because after you upgrade through a few kernel releases the size of the thin client just gets fatter and fatter
| |
| 10:23 | <alkisg> ftherese: try `apt-get clean` on the chroot
| |
| 10:23 | ..and also purge any older kernels
| |
| 10:24 | It shouldn't grow larger over time...
| |
| 10:24 | <ftherese> I used to do that... but it always seemed to continue to grow
| |
| 10:24 | I think now it has to do with the chromium versions
| |
| 10:24 | * alkisg always mounts /var/cache/apt/archives nowadays, so it's faster and also he doesn't have to run apt-get clean... | |
| 10:25 | <sbalneav> http://github.com/herzi/p2p-dbus
| |
| 10:25 | <ftherese> ?
| |
| 10:25 | what's that
| |
| 10:25 | <johnny> sbalneav, i posted that here for your yesterday :)
| |
| 10:25 | but you weren't around
| |
| 10:27 | <ftherese> timezone is still incorrect
| |
| 10:27 | <sigh>
| |
| 10:27 | oh well... it isn't like anyone stares that the login screen to know what time it is
| |
| 10:28 | <thunsucker_> ftherese: someone the other day was in here, and I believe found a way to make that black text white, so it wouldn't show up
| |
| 10:28 | <ogra> are you sure its the timezone and not the clock itself ?
| |
| 10:28 | <alkisg> ftherese: try to set UTC=yes or no in the chroot
| |
| 10:28 | /etc/default/rcS - compare server & chroot
| |
| 10:29 | <sbalneav> johnny: hah, cool
| |
| 10:29 | Great minds think alike
| |
| 10:29 | fools seldom differ :)
| |
| 10:30 | <ftherese> after signing in the time is correct
| |
| 10:30 | it is only on the LDM screen
| |
| 10:30 | <alkisg> ftherese: grep UTC /opt/ltsp/i386/etc/default/rcS
| |
| 10:30 | klausade has joined #ltsp | |
| 10:31 | <ftherese> UTC=yes
| |
| 10:31 | I tried using timezone="CET" #(central europe)
| |
| 10:31 | and I tired timezone = "UTC+0100"
| |
| 10:31 | <alkisg> ftherese: try with UTC=no
| |
| 10:32 | <ogra> on the login screen you see the actual hardwareclock of the thin client ...
| |
| 10:32 | if you logged in you see the time on the server
| |
| 10:32 | <ftherese> ahhh...
| |
| 10:32 | <ogra> if the clock on the client is wrong you can play for ages with timezones and wont get it right :)
| |
| 10:33 | <ftherese> well... this is actually the same problem with two different computers
| |
| 10:33 | maybe both of them have the wrong machine time
| |
| 10:33 | <ogra> what you can do is set up an ntp server on the server and make the clients just update their time on boot
| |
| 10:33 | <ftherese> I've only checked on those two also

| 10:55 | <nubae> alkisg: good news, that worked...
| |
| 10:55 | <alkisg> nubae, which one?
| |
| 10:55 | <nubae> so something in the ppa fixed it
| |
| 10:55 | <alkisg> Ah, ok, a solved bug ;)
| |
| 10:55 | <nubae> heh, updating the chroot
| |
| 10:55 | yeah except we have no idea which bug now :-)
| |
| 10:56 | anyway, I guess I can write up a solution for anyone wishing to use Mint for ltsp
| |
| 10:57 | <alkisg> nubae: you could do it with EXTRA_MIRROR to be easier, instead of updating the chroot later on
| |
| 10:57 | <nubae> yeah true
| |
| 10:57 | <alkisg> nubae: have a look at my fat client page in the wiki, I mention about it (and stgraber's ppa)
| |
| 10:57 | <nubae> it feels a bit weird writing a solution without knowing what problem it fixes though
| |
| 10:58 | I guess the fixes will be in Lucid
| |
| 10:58 | <alkisg> Yup, ltsp 5.2 is in lucid
| |
| 10:59 | <nubae> feels like the numbers go up so slowly for ltsp
| |
| 10:59 | <ftherese> that is actually kind of reassuring
| |
| 11:00 | <nubae> for stability, yeah
| |
| 11:01 | <ogra> well, ltsp 5 is at revision 1702 ... depends what numbers you watch ;)
| |
| 11:01 | <nubae> but its still quite unpredictablle from one distro to another
| |
| 11:01 | * sbalneav declares ltsp 5.2 == LTSP 7 | |
| 11:01 | <nubae> heh
| |
| 11:01 | <ogra> sbalneav, are you SuSE ?
| |
| 11:01 | <nubae> would work for marketing
| |
| 11:01 | windows more like
| |
| 11:01 | <ogra> SuSE predates that
| |
| 11:01 | they made such a jump before
| |
| 11:02 | <nubae> they started slowing down with their numbers
| |
| 11:02 | 11.3 is like 2 years of 11
| |
| 11:02 | little correlation with their release numbers unfortunately
| |
| 11:03 | * sbalneav declares LTSP 7 == "Incontinent Ibis" release | |
| 11:03 | <ogra> well, it might be renamed to elliotOS anyway, who knows :)
| |
| 11:03 | <nubae> elliotOS?
| |
| 11:03 | whats that?
| |
| 11:03 | * sbalneav declares sbalneav "King of All Newts" | |
| 11:04 | <ogra> nubae, http://www.reuters.com/assets/commentsChild?articleId=USTRE6214QN20100302&headline=Elliott+offers+to+take+Novell+private+for+$2+bln&channel=innovationNews

| |
| 11:07 | Man
| |
| 11:07 | Been a long time since I played those sorts of games
| |
| 11:07 | <ogra> makes one feel old, eh ?
| |
| 11:07 | <nubae> I downloaded world of goo yesterday...
| |
| 11:08 | <sbalneav> I still play nethack from time to time
| |
| 11:08 | I got my kids into it for a while.
| |
| 11:08 | <ogra> heh
| |
| 11:08 | <sbalneav> nethack, rogue, the old Zork series
| |
| 11:08 | fun times.
| |
| 11:08 | * ogra switched to falcons crest a while ago | |
| 11:08 | <sbalneav> nethack's still being maintained, oddly enough.
| |
| 11:08 | <ogra> but work doesnt really leave me time
| |
| 11:09 | * ogra has to extend ARMs ... http://www.bild-hoster.de/images/Gofmann/saw.jpg | |
| 11:09 | <nubae> no xbox, no wii?
| |
| 11:10 | <sbalneav> My kids have an Xbawks. Sometimes they even let me play.
| |
| 11:10 | <nubae> hehe
| |
| 11:10 | <sbalneav> Only game on it I've REALLY enjoyed so far is Portal.
| |
| 11:10 | * ogra has a wii he uses twice a year or so | |
| 11:10 | <nubae> wii is more fun
| |
| 11:11 | I softmodded mine
| |
| 11:12 | the sports games are fun, and for retro nostalgia, new super mario bros
| |
| 11:13 | <ftherese> just curious: is there a script that can be run on the server as a thin client is logging in, without the script being in the thin client?
| |
| 11:14 | <johnny> sbalneav, ...
| |
| 11:14 | <ftherese> in other words... can I write a script that will delete a guest user's home directory contents without having to rebuild the chroot?
| |
| 11:14 | <johnny> http://chris-lamb.co.uk/2008/01/24/can-you-get-cp-to-give-a-progress-bar-like-wget/5
| |
| 11:14 | <ogra> you can write something that checks for LTSP_CLIENT on the server and run it from /etc/xdg/autostart
| |
| 11:14 | <johnny> sbalneav, .. thats' for you
| |
| 11:14 | fun hackiness
| |
| 11:15 | <ogra> johnny, yeah ... /me saw that this morning
| |
| 11:16 | <alkisg> ogra, stuff in /etc/xdg/autostart do not block, so they could even start after the user has opened firefox... is there some place _before_ that, that also blocks?
| |
| 11:16 | <ogra> hmm, good question
| |
| 11:16 | to be honest, i dont know
| |
| 11:18 | <sbalneav> johnny: yeah, nothing like slowing down a copy by 4-5 times by running it through strace just so you can get a progress bar.
| |
| 11:18 | <johnny> of ourse
| |
| 11:18 | still a neat hack tho
| |
| 11:18 | <alkisg> johnny: rsync does have a bar ;)
| |
| 11:19 | Gadi: could that SOUND_DAEMON thing be also used for fat clients? I.e. make it default to false when LTSP_FATCLIENT=True?
| |
| 11:20 | <Gadi> alkisg: if thats the desired behavior?
| |
| 11:20 | <alkisg> Gadi, what does it do exactly?
| |
| 11:20 | <Gadi> SOUND_DAEMON=False will simply not run pulseaudio on boot and not spit out a warning message
| |
| 11:21 | all of our other values do *something*
| |
| 11:21 | we didnt have one that does *nothing*
| |
| 11:21 | :)
| |
| 11:21 | <alkisg> :)
| |
| 11:21 | <Gadi> if all you run is rdesktop, you probably do not want pulseaudio running
| |
| 11:22 | it just adds overhead and degrades performance
| |
| 11:24 | <alkisg> Sorry for fat clients we set SOUND=False so that covers pulse as well :)
| |
| 11:25 | <nubae> is there an updated LDAP howto for karmic/lucid?
| |
| 11:28 | <alkisg> Yup, sbalneav has uploaded one in the edubuntu wiki
| |
| 11:28 | I don't remember the link offhand...
| |
| 11:28 | <nubae> oh nice... I'll take a look
| |
| 11:29 | <alkisg> I wonder if we can use ldm in standalone workstations, to get ssh authentication instead of using ldap...
| |
| 11:29 | <thunsucker_> nubae: https://wiki.edubuntu.org/Edubuntu/WikiSite/SimpleLDAPSetup
| |
| 11:29 | <alkisg> (but now with the fat clients plugin I don't care much... :D)
| |
| 11:29 | <ogra> alkisg, if anyone every makes it a real dm
| |
| 11:29 | *ever
| |
| 11:29 | <alkisg> ogra, you mean the debconf entry?
| |
| 11:29 | <ogra> i mean the whole packaging
| |
| 11:30 | etyack has left #ltsp | |
| 11:30 | <nubae> thanks
| |
| 11:30 | <ogra> you have to fulfill a lot of requirements to have it be a real dm in debian or ubuntu
| |
| 11:30 | chrishuttman has joined #ltsp | |
| 11:30 | etyack has joined #ltsp | |
| 11:30 | <alkisg> ogra, any links, except for the pax-dm page?
| |
| 11:31 | <chrishuttman> i was here yesterday, having trouble with an ubuntu distro upgrade to 10.04, decided to just reinstall 9.10
| |
| 11:31 | wanted to say thanks for the 10.04 help
| |
| 11:31 | and also ask is sabayon still the way to go to manage thin client users?
| |
| 11:31 | <ogra> alkisg, i think vagrant researched that once and gave up
| |
| 11:32 | <alkisg> ogra, yeah, he gave me that link, I think we're OK on that part
| |
| 11:32 | <sbalneav> chrishuttman: Sabayon is definitely one of the methods.
| |
| 11:32 | You'll need to install Sabayon packages from my PPA
| |
| 11:33 | I'm now one of the upstream Sabayon maintainers.
| |
| 11:33 | <ogra> alkisg, next would be to have your own upstart job in ldm to make it independent of ltsp-client ... that will be the hardest part to do without breaking ltsp :)
| |
| 11:33 | <chrishuttman> are the ones in the main channels broken?
| |
| 11:33 | <sbalneav> chrishuttman: Correct.
| |
| 11:33 | <chrishuttman> awesome
| |
| 11:33 | <sbalneav> They've been fixed in lucid.
| |
| 11:33 | <chrishuttman> ha :)
| |
| 11:33 | <alkisg> ogra, well anyway I suppose the new libpam_ssh that sbalneav is looking to make will fulfill that need better than a packaged ldm :)
| |
| 11:34 | <chrishuttman> sbalneav: if i'm starting from scratch using your PPA's installs, should I be good?
| |
| 11:34 | etyack has left #ltsp | |
| 11:37 | <chrishuttman> and once i add your ppa, do i need to remove the original sabayon package?
| |
| 11:39 | <alkisg> chrishuttman: sudo add-apt-repository ppa:sbalneav
| |
| 11:39 | sudo apt-get update
| |
| 11:39 | That should be all.
| |
| 11:40 | <chrishuttman> thanks guys
| |
| 11:40 | <alkisg> The sabayon package would be automatically updated - don't worry about removing the old package etc.
| |
| 11:40 | <sbalneav> chrishuttman: no, they'll be updated
| |
| 11:40 | no need to worry about removing the old package

| 12:29 | <jontheisg> hello
| |
| 12:30 | anybody home?
| |
| 12:31 | <johnny> never ask that..
| |
| 12:31 | !ask
| |
| 12:31 | <ltspbot`> johnny: "ask" :: Don't ask to ask a question, simply ask it, and if someone knows the answer, they'll respond. Please hang around for at least 15 minutes after asking a question, as not everybody constantly monitors the channel.
| |
| 12:32 | <jontheisg> ok, sorry. so I have a question - where does one find instructions for LTSP setup with Ubuntu 9.04?
| |
| 12:32 | aim is for help/documentation with multiserver environment
| |
| 12:33 | <nubae> !docs
| |
| 12:33 | <ltspbot`> nubae: "docs" :: For the most current documentation, see https://sourceforge.net/apps/mediawiki/ltsp/index.php?title=Ltsp_LtspDocumentationUpstream
| |
| 12:33 | <nubae> and the wiki should help too
| |
| 12:33 | !wiki
| |
| 12:33 | <ltspbot`> nubae: "wiki" :: the LTSP wiki. You can find it at http://wiki.ltsp.org
| |
| 12:34 | <nubae> hmmm it lies, best wiki is actually here: https://help.ubuntu.com/community/UbuntuLTSP/
| |
| 12:34 | johnny: does sound work on kde clients by default for karmic?
| |
| 12:34 | <johnny> i have no idea
| |
| 12:34 | i don't use kde
| |
| 12:34 | i would assume so..
| |
| 12:34 | but.. who knows ..
| |
| 12:35 | kde is switching to pulseaudio at some point
| |
| 12:35 | or perhaps already has..
| |
| 12:35 | <nubae> hmm yeah doesnt work for me, but I'm wondering if its kde related or something else
| |
| 12:35 | <jontheisg> ok, new to LTSP but not IT.. are network setups that are multi-server meant to have more than one tftpboot system?
| |
| 12:35 | <johnny> multiserver?
| |
| 12:35 | just different application servers?
| |
| 12:35 | i think you only need one tftpboot dir..
| |
| 12:35 | could be wrong tho..
| |
| 12:35 | <nubae> they can but dont have to
| |
| 12:36 | <jontheisg> the intent is to spread the thinclient load across multiple server hardware for best performance
| |
| 12:36 | <nubae> using clusterltsp gives u multiple app servers
| |
| 12:36 | <jontheisg> can it be done without clustering or no?
| |
| 12:36 | <nubae> thats clusterltsp jontheisg
| |
| 12:36 | well by default LTSP is non clustered
| |
| 12:37 | but it doesnt span across hardware on the server end
| |
| 12:37 | <jontheisg> ok. understood. does the wiki describe setup of clusterltsp
| |
| 12:37 | <nubae> it does it on the client end
| |
| 12:37 | yes it does
| |
| 12:37 | <johnny> it does?
| |
| 12:37 | they have their own site
| |
| 12:37 | <nubae> works quite well in later Ubuntu distros
| |
| 12:37 | <jontheisg> ok ill check and read
| |
| 12:37 | we were going to put up 8.04LTS Ubuntu for LTSP - but I am leaning toward 9.04. Thoughts?
| |
| 12:37 | <nubae> the link in the wiki might send u to cluster specific link
| |
| 12:38 | I'd wait for LTS version
| |
| 12:38 | <jontheisg> around 200 clients and 3 hardware servers available.
| |
| 12:38 | <nubae> 10.04
| |
| 12:38 | y would u want 9.04 and not 9.10?
| |
| 12:39 | the LTS should be out in 2 months I believe, or is it 4...
| |
| 12:39 | <jontheisg> generic ubuntu question - is 9.10 less stable than 9.04? I have had more success with 9.04??
| |
| 12:39 | its due in April
| |
| 12:39 | 10.04
| |
| 12:39 | <nubae> I've tested cluster on karmic, and that ran quite well
| |
| 12:39 | I'm sure it runs on lucid too
| |
| 12:39 | <jontheisg> kewl
| |
| 12:39 | right now there are 2 network subnets that are servicing two client pools
| |
| 12:40 | <nubae> johnny: any idea how I can test my sound setup on kde clients?
| |
| 12:40 | <jontheisg> we are trying to flatten network, increase LTSP performance and improve network design. Right now there are two LTSP4? on CentOS
| |
| 12:40 | <nubae> there seems to be no documentation for it
| |
| 12:41 | staffencasa has quit IRC | |
| 12:41 | <jontheisg> We are going to take them to Ubuntu-land in the near future
| |
| 12:41 | <nubae> well, u'll certainly see a difference with ltsp 5.2
| |
| 12:41 | <johnny> no nubae .. no kde ever here..
| |
| 12:41 | <nubae> darn, I have no idea where to even start...
| |
| 12:42 | <jontheisg> any thoughts on using proxmox or vmware or virtualization on ltsp server cluster?
| |
| 12:42 | anivair has quit IRC | |
| 12:42 | <nubae> jontheisg: thats how I did it
| |
| 12:42 | <jontheisg> really. excellent
| |
| 12:42 | <nubae> using proxmox
| |
| 12:43 | the howto is based on that
| |
| 12:43 | <jontheisg> cool.. is that the wiki or something else?
| |
| 12:43 | jontheisg is now known as jontheisguy | |
| 12:44 | <nubae> seperating across vms makes a lot of sense since its the one thing where LTSP is pretty vulnerable since everything runs off one machine otherwise and the server going down means death to all clients
| |
| 12:45 | <jontheisguy> right
| |
| 12:45 | hey im looking at wiki.ltsp.org - where are the proxmox items?
| |
| 12:45 | <nubae> https://help.ubuntu.com/community/UbuntuLTSP/LTSP-Cluster
| |
| 12:45 | its in the ubuntu wiki
| |
| 12:46 | but is probably relevant for other supperted distros too
| |
| 12:46 | I'm planning or rolling out cluster myself actually for a new school setup
| |
| 12:47 | <jontheisguy> same here.. volunteering at a school in CO, USA
| |
| 12:47 | <nubae> the openvz pages talk about proxmox
| |
| 12:47 | well openvz is proxmox iirc
| |
| 12:48 | <jontheisguy> @nubae sure.. where is your school located?
| |
| 12:48 | <nubae> Spain
| |
| 12:48 | Southern coast
| |
| 12:48 | <jontheisguy> fantastico
| |
| 12:48 | <nubae> :-)
| |
| 12:49 | <jontheisguy> so with this new info - gracias a nubae & johnny - I think I am going to look more into LTSP cluster setup
| |
| 12:49 | <nubae> yeah setting something up for students who have just finished school, or expats wanting to learn computers, office the internet
| |
| 12:49 | thunsucker_ has quit IRC | |
| 12:50 | <nubae> don't get overwhelmed by it, there are a lot of instructions
| |
| 12:50 | <jontheisguy> just finished school - as in college - or secondary?
| |
| 12:50 | <nubae> but the end result is worth it
| |
| 12:50 | yeah, diploma based... not really college/uni
| |
| 12:50 | based on British system of education
| |
| 12:51 | <jontheisguy> cool
| |
| 12:51 | mikkel has joined #ltsp | |
| 12:51 | <nubae> setting it up with a couple IT teachers, and we've all worked in various schools in the area
| |
| 12:51 | <jontheisguy> excellent
| |
| 12:51 | <nubae> I'm just unsure about the Linux angle
| |
| 12:52 | leio has quit IRC | |
| 12:52 | <nubae> but I believe people will accept it if we make the underlying OS not so important
| |
| 12:52 | <jontheisguy> do you plan to seperate any services or all on LTSP cluster?
| |
| 12:52 | CUPS, Samba, NIS, etc
| |
| 12:52 | <nubae> yeah I'll separate services in VMs
| |
| 12:52 | LDAP instead of NIS
| |
| 12:53 | so windows/osx clients can log on
| |
| 12:53 | Appiah has quit IRC | |
| 12:53 | fudoreaper has quit IRC | |
| 12:53 | <jontheisguy> Amen to that
| |
| 12:53 | Appiah has joined #ltsp | |
| 12:53 | <jontheisguy> one of the side projects for me is to create LDAP/Radius server
| |
| 12:53 | should be interesting
| |
| 12:53 | fudoreaper has joined #ltsp | |
| 12:54 | <nubae> yeah I set up LDAP for dapper, but there are howtos for the latest distros now so should be relatively straight forward
| |
| 12:55 | <jontheisguy> any gotchas to look out for with LDAP setup. I found documentation for it, just wanting any suggestions regarding best practices ;)
| |
| 12:55 | leio has joined #ltsp | |
| 12:57 | <nubae> not really sure, last time I took a look was a couple years back with dapper, but I'm actually installing right now so I'll let you know if I run into anything
| |
| 12:57 | <jontheisguy> that'd be great.
| |
| 12:57 | thanks for your patiencia

| 13:06 | alkisg: u have experience with kde clients, my sound isnt working... wondering where I should look
| |
| 13:06 | ?
| |
| 13:07 | <jontheisguy> @nubae have you checked into which module(s) are being loaded in the lts.conf?
| |
| 13:08 | <nubae> jontheisguy: nope, but sound should be loaded by default, in any case I'll double check, its a good idea

| 13:28 | etyack has joined #ltsp | |
| 13:30 | <jontheisguy> im going to work with some virtualized servers... thanks nubae and others who helped!
| |
| 13:30 | jontheisguy has quit IRC | |
| 13:33 | <nubae> I get /etc/X11/Xsession.d/80_ltsp-sound: 7: /usr/bin/asoundconf: not found
| |
| 13:33 | in my logs (xsession-errors), any ideas?
| |
| 13:38 | looks like this is a deep issue of kde... I thought kde was more developed for ltsp now...
| |
| 13:42 | super weird, so pulseaudio works locally, but when I try and play any media it plays on the server
| |
| 13:43 | doing a test however sound works on the client
| |
| 13:44 | <abeehc> what's kde use, esd?
| |
| 13:44 | <johnny> no..
| |
| 13:45 | they used to use arts..
| |
| 13:45 | <nubae> its using pulse now
| |
| 13:45 | <johnny> ah
| |
| 13:45 | <nubae> and it runs fine when I test
| |
| 13:45 | they split it into video /audio /communication
| |
| 13:45 | I set pulse as default, but when I play a media file it plays on the server
| |
| 13:46 | <abeehc> what are you using to play
| |
| 13:46 | <nubae> however a sound test plays on the client
| |
| 13:46 | makes no sense
| |
| 13:46 | <abeehc> and what's a sound test?
| |
| 13:46 | vs. playing something
| |
| 13:46 | <nubae> system settings >> sound
| |
| 13:46 | <abeehc> i would imagine first class kde apps should obey the pulse setting
| |
| 13:46 | and work as normal?
| |
| 13:47 | but random media clients will do random things?
| |
| 13:47 | what's the app that plays on the server
| |
| 13:47 | <nubae> lets see let me try vlc
| |
| 13:47 | <abeehc> vlc is flexible enough you can tell it what sound daemon to interact with i'm sure
| |
| 13:48 | <nubae> lol ure right... mplayer plays locally
| |
| 13:48 | draganplayer/vlc play on server
| |
| 13:48 | now that is weird
| |
| 13:48 | <abeehc> i see a package in jaunty repos for vlc-plugin-pulse
| |
| 13:49 | <nubae> well mplayer suits me fine, I'm just used to using kde
| |
| 13:49 | I mean vlc
| |
| 13:49 | <abeehc> right on
| |
| 13:49 | <nubae> vlc-plugin-pulse was already installed
| |
| 13:49 | <abeehc> This plugin adds support for PulseAudio to the VLC media player. To activate the audio output module, use the `--aout pulse' flag or select the `pulse' audio output plugin from the preferences menu.
| |
| 13:50 | i imagine that might work I dunno
| |
| 13:50 | i haven't struggled with sound just yet
| |
| 13:50 | <nubae> hmmm my vlc is randomly crashing
| |
| 13:50 | but if it works with mplayer theres probably a way
| |
| 13:50 | now for local devices :-)
| |
| 13:51 | I guess there aren't that many people using kde ltsp
| |
| 13:53 | <abeehc> i'm not too sure
| |
| 13:54 | <nubae> video is really slow though, I guess this is cause I have a X1350 ati
| |
| 13:54 | I might have to install the prop drivers in the chroot
| |
| 13:56 | yeah cant do fullscreen at all

I can follow the K12Linux Quickstart Guide that appears on the desktop and get the networking operational, but I am having a tough time remembering how to install the K12 apps. In the back of my mind it was an RPM I install, but I can't recall the name, nor am I having any luck with the documentation on the K12linux wiki. Wishing the line with that solution w

| 16:26 | <yotux> Is there a location that thin clients log information for boots
| |
| 16:32 | <_UsUrPeR_> yotux: on the client itself, in /var/log
| |
| 16:33 | in order to access that, create the following file: /var/lib/tftpboot/ltsp/i386/lts.conf . In the file, put the following: http://pastebin.com/QKxWxN7P
| |
| 16:33 | <yotux> my thin client will not boot so that would be hard to get to
| |
| 16:33 | <_UsUrPeR_> after boot, you should be able to access shell by pressing CTRL+ALT+F2
| |
| 16:34 | yotux: in that case, check /var/log/syslog
| |
| 16:34 | <yotux> that would be on the server correct?
