Channel log from 24 March 2010 (all times are UTC)
| 00:02 | alkisg has joined #ltsp | |
| 00:06 | <amnesia> yea, I'm not finding anything on except ubuntu and debian
| |
| 00:09 | <alkisg> amnesia: are you supposed to export /opt/ltsp? Or is it /opt/ltsp/i386, i.e. the chroot?
| |
| 00:10 | <vagrantc> it's fine to export /opt/ltsp
| |
| 00:10 | you can mount sub-dirs.
| |
| 00:10 | in fact, it's recommended to export /opt/ltsp
| |
| 00:11 | <amnesia> alkisg: I tried both ways
| |
| 00:11 | <alkisg> And the client initramfs knows where to look? Or does it need some extra configuration to know what/where to mount it?
| |
| 00:12 | <vagrantc> alkisg: dhcp tells it where to look
| |
| 00:12 | <alkisg> Ah, right. :)
| |
| 00:13 | <amnesia> its funny i like a distro that nobody supports
| |
| 00:13 | <alkisg> So if I exported /opt/ltsp as /my-nfs-root-dir, I'd put server-ip:/my-nfs-root-dir/i386 in dhcp, correct
| |
| 00:13 | ?
| |
| 00:14 | <amnesia> option root-path "192.168.0.1:/opt/ltsp/i386";
| |
| 00:14 | that's what I got
| |
| 00:14 | <alkisg> And in exports?
| |
| 00:14 | <amnesia> ./opt/ltsp 192.168.0.0/255.255.255.0(ro,no_root_squash,sync)
| |
| 00:15 | <alkisg> Doesn't it need to be the same?
| |
| 00:15 | /opt/ltsp/i386 again there?
| |
| 00:15 | <amnesia> it didnt seem to matter
| |
| 00:15 | either way 2 hours a piece of the 'nfs server not responding still trying'
| |
| 00:15 | :>
| |
| 00:16 | i removed all the lines from hosts.deny hosts.allow
| |
| 00:16 | <alkisg> Did you try break=mount in pxelinux.cfg/default, to manually try things from inside the initramfs?
| |
| 00:17 | * alkisg has never seen slackware, and he's just throwing out ideas... | |
| 00:17 | <amnesia> Not familiar with that nor how to do that tbh
| |
| 00:17 | first time i've ever done anything with PXE
| |
| 00:17 | <vagrantc> alkisg: /etc/exports is perfectly ok with mounting sub-dirs. i assure you. having been an LTSP developer for 5 years, and another thin client developer for 4 years above and beyond that...
| |
| 00:17 | :)
| |
| 00:18 | <amnesia> tell me how and i'll try it :D
| |
| 00:18 | <alkisg> vagrantc: I believe you, I was just trying to learn, it was a question :)
| |
| 00:19 | <amnesia> break=mount
| |
| 00:19 | where does this get inserted
| |
| 00:19 | <vagrantc> alkisg: the default on debian in /etc/exports is: /opt/ltsp *(ro,no_root_squash,async,no_subtree_check)
| |
| 00:19 | <cyberorg> moin all
| |
| 00:20 | <vagrantc> amnesia: you have an ubuntu chroot on your slackware server?
| |
| 00:20 | <amnesia> no
| |
| 00:20 | <vagrantc> hacking up a slackware chroot?
| |
| 00:20 | <cyberorg> here is new openSUSE Edu Li-f-e release with LTSP out of the box http://lizards.opensuse.org/2010/03/24/li-f-e-updated-2/
| |
| 00:21 | <amnesia> but im bout to stick your line there in my exports
| |
| 00:22 | <alkisg> Hi cyberorg. amnesia: I'm not seeing references for slackware/break=mount in google, so it might not apply there.
| |
| 00:22 | vagrantc: he's using ltsp 4.2
| |
| 00:22 | <vagrantc> oh my
| |
| 00:22 | <amnesia> actually 4.1 now
| |
| 00:22 | im trying them all
| |
| 00:23 | eventually I'm hoping something will work considering I can't find a package for 5 series
| |
| 00:24 | <alkisg> amnesia: you could try exporting an ubuntu chroot or an opensuse image etc... you'd just need to prepare it in a separate machine...
| |
| 00:24 | <vagrantc> amnesia: it probably wouldn't be too difficult to port to ltsp5 ...
| |
| 00:24 | amnesia: it just takes someone with the will to do so.
| |
| 00:24 | <cyberorg> amnesia, what distro are you using?
| |
| 00:24 | <amnesia> sw
| |
| 00:25 | <cyberorg> what kind of clients you got?
| |
| 00:25 | <amnesia> well
| |
| 00:25 | im testing with a dell inspiron 1000
| |
| 00:25 | i dropped one too many times harddrive failed and I'm too cheap to buy a new one
| |
| 00:26 | <cyberorg> if you have clients with about 256M ram, and +1Ghz (or little less) you can try this: http://en.opensuse.org/LTSP/Other_Distros
| |
| 00:26 | <amnesia> yea this laptop here has that
| |
| 00:26 | brb
| |
| 00:27 | <cyberorg> and get started on porting LTSP in a proper way :)
| |
| 00:28 | <amnesia> interesting
| |
| 00:28 | ihu this old stuff, but for some reason my distro is stuck in history
| |
| 00:28 | all packages are ancient
| |
| 00:29 | <johnny> uhmm.. or you could just switch distros amnesia .. it'd be easier..
| |
| 00:29 | <amnesia> but lets see what happens with this
| |
| 00:29 | <johnny> ubuntu makes ltsp easy
| |
| 00:29 | <amnesia> Yeah -- that's not too feasible, good thought tho
| |
| 00:32 | aha 3 gbs
| |
| 00:33 | for life dvd
| |
| 00:33 | thank god for 50mb connection :D
| |
| 00:35 | <cyberorg> amnesia, we've got kitchen sink in there too ;)
| |
| 00:35 | <amnesia> i hear ya man
| |
| 00:35 | 12 minutes to go
| |
| 00:35 | let me ask you -- I have another box/server
| |
| 00:36 | but I use the box I'm trying to host LTSP on as a gateway aswell with DHCPD etc
| |
| 00:36 | how would that work without setting up a different dotted notation segment
| |
| 00:37 | if I were to just use SuSE on it
| |
| 00:37 | <cyberorg> to create gateway you need minimum two interfaces, both in different network
| |
| 00:37 | <johnny> you'll get better support for ubuntu here tho amnesia ..
| |
| 00:37 | just sayin
| |
| 00:37 | <amnesia> yeah--I have that covered cyberorg
| |
| 00:38 | <cyberorg> johnny, suse users don't need support ;)
| |
| 00:38 | <vagrantc> heh
| |
| 00:38 | <amnesia> that's funny mostly all of those distros are souped up windows linux
| |
| 00:39 | but ltsp is supported :{
| |
| 00:39 | <johnny> that is exactly not true
| |
| 00:39 | cyberorg, lots of people come here
| |
| 00:39 | <cyberorg> amnesia, distros does not matter much, ltsp is same on all
| |
| 00:39 | <johnny> asking for help with ltsp on suse
| |
| 00:39 | <amnesia> cyberorg -- google slackware/ltsp
| |
| 00:39 | <johnny> we send them to kiwi.. and they come bakc saying that nobody is there
| |
| 00:39 | <amnesia> you'll find almost nothing
| |
| 00:39 | <johnny> amnesia, that's cuz nobody ported it
| |
| 00:39 | amnesia, i ported gentoo..
| |
| 00:40 | that's not exactly souped up windows linux..
| |
| 00:40 | <amnesia> no i like gentoo
| |
| 00:40 | <johnny> problem is.. nobody has cared enough about slackware and ltsp
| |
| 00:40 | that's all it is
| |
| 00:40 | <cyberorg> johnny, yeah, i know last week few of them came in here,they were students hacking on getting fatclient support integrated in easy-ltsp
| |
| 00:40 | <johnny> until somebody cares enough to port it..
| |
| 00:40 | <amnesia> heh, apparently nobody cares about slackware
| |
| 00:40 | <johnny> truly
| |
| 00:40 | i stopped caring about slackware in 2001
| |
| 00:41 | <amnesia> all i ever needed it for was httpd an my srvs
| |
| 00:41 | everytime i wanted to do something different i get shunned by its support group
| |
| 00:42 | but i been on it for along time
| |
| 00:43 | if u think ubuntu is the way to go i'll setup my other box for it
| |
| 00:43 | but i'm going to try to make this work first
| |
| 00:44 | i dont like getting beaten
| |
| 00:48 | try2free has joined #ltsp | |
| 00:49 | <alkisg> stgraber: /opt/ltsp/i386/usr/share/initramfs-tools/conf.d/ltsp now doesn't contain "nbd", so ltsp-update-image doesn't do anything...
| |
| 00:49 | (in 5.2.1)
| |
| 00:50 | (if $(grep nbd "${CHROOT}/${CONFFILE}" > /dev/null 2>&1); then)
| |
| 00:55 | stgraber: it looks like a packaging error, 'ltsp' got in conf.d instead of conf-hooks.d
| |
| 00:58 | stgraber: yup, in ltsp-client-core.install:
| |
| 00:58 | client/initramfs/conf.d/ltsp usr/share/initramfs-tools/conf.d
| |
| 00:58 | client/initramfs/conf-hooks.d/ltsp usr/share/initramfs-tools/conf.d
| |
| 00:59 | <vagrantc> that seems like a useless check ...
| |
| 00:59 | <alkisg> It did reveale a packaging problem though :D
| |
| 00:59 | johnny has left #ltsp | |
| 00:59 | <vagrantc> if it's not a file in a configurable location, there's no reason to check for it
| |
| 01:00 | japerry has joined #ltsp | |
| 01:00 | <vagrantc> on debian, that file will be present, but not necessarily used
| |
| 01:00 | <alkisg> I think that file is where we can switch to NFS, if any ubuntu user wants that...
| |
| 01:00 | <amnesia> cyberorg: so uh
| |
| 01:00 | <alkisg> https://help.ubuntu.com/community/UbuntuLTSP/LTSPWithoutNFS
| |
| 01:01 | <amnesia> how's this gonna work
| |
| 01:01 | johnny has joined #ltsp | |
| 01:01 | <vagrantc> alkisg: but by shipping it in a package outside of /etc, it makes it effectively unconfigurable... it needs to be in a place where the sysadmin can change it and expect the changes to be respected by upgrades.
| |
| 01:02 | <cyberorg> amnesia, boot up the iso in a VM or dd it to 4G usb stick or burn a DVD to boot it :)
| |
| 01:02 | <amnesia> yea
| |
| 01:02 | i burnt it already
| |
| 01:02 | now i gotta find something to install it on
| |
| 01:02 | <cyberorg> no need to install
| |
| 01:03 | http://en.opensuse.org/LTSP/Quick_start configure ltsp in live image, create tarball, extract it in sw
| |
| 01:03 | <amnesia> live cd you dont say
| |
| 01:03 | :D
| |
| 01:03 | <alkisg> vagrantc: should it be in $ROOT/etc/initramfs-tools/conf.d/ instead?
| |
| 01:03 | <cyberorg> tarball from live DVD, extract it in sw as per http://en.opensuse.org/LTSP/Other_Distros
| |
| 01:03 | <amnesia> yea
| |
| 01:03 | im trackin now
| |
| 01:03 | welp um
| |
| 01:03 | brb?
| |
| 01:04 | <cyberorg> you can test ltsp once you configure it in live DVD by booting a client
| |
| 01:04 | <vagrantc> alkisg: i don't get why it's even being checked at all...
| |
| 01:04 | alkisg: running ltsp-update-image should only be done if you're going to use NBD ...
| |
| 01:05 | <alkisg> vagrantc: well I suppose Gadi put it there to "protect" the people that use nfs on Ubuntu... I don't know.
| |
| 01:05 | I get your point.
| |
| 01:05 | <vagrantc> that was added in 5.2.1 ?
| |
| 01:05 | <alkisg> No, it was there for 5.2 I think
| |
| 01:05 | <vagrantc> ugh.
| |
| 01:10 | <cyberorg> in kiwi the initrd looks for config.MAC or config.default on tftp server to find out if the client wants NFSROOT, NBDROOT or AOEROOT
| |
| 01:11 | nothing has to be changed when creating initrd, admin can select which image goes to which client if they want different images
| |
| 01:11 | <alkisg> vagrantc: bzr says that line has been there since "before time" :)

| 06:51 | <uberiain> hello
| |
| 06:52 | i have updated ltsp-server to version 5.2.1-0ubuntu1 today
| |
| 06:52 | and the client don't boot
| |
| 06:52 | made ltsp-update-image --arch i386 --server 10.228.45.137
| |
| 06:52 | and return without create image to boot
| |
| 06:54 | these file /opt/ltsp/i386/usr/share/initramfs-tools/conf.d/ltsp
| |
| 06:54 | has this content
| |
| 06:54 | # Required to get a splash on Lucid
| |
| 06:54 | FRAMEBUFFER=y
| |
| 06:54 | --------
| |
| 06:55 | it's correct? must modify this file
| |
| 06:55 | server is Lucid 10.04
| |
| 06:55 | amd64
| |
| 06:55 | the last version of ltsp-server work well
| |
| 06:55 | any suggestion?

| 07:39 | <stgraber> if he'd waited for a few more minutes I could have told him to apt-get update + apt-get dist-upgrade ;)
| |
| 07:39 | alkisg: thanks for noticing the mistake. That's now fixed.
| |
| 07:39 | <alkisg> Thanks stgraber :)
| |
| 07:40 | <stgraber> alkisg: I also disabled chroot compression by default in -0ubuntu3. Chroot will be aproximately 40% bigger but also 100% more stable ;)
| |
| 07:40 | During tests I made recently, all stability issues at boot time simply vanished once compression is disabled
| |
| 07:40 | <alkisg> Yey! /me never liked nbd compression...
| |
| 07:41 | <stgraber> an uncompressed standard chroot is 566M
| |
| 07:41 | so really not that bad
| |
| 07:44 | <alkisg> Compressing an 11 Gb fat chroot takes ...days :D
| |
| 07:45 | Most modern disks are 1Tb, so no need for compression.. and I don't think network bandwidth will be too affected
| |
| 07:51 | stgraber: just wondering, where is the ubuntu ltsp source maintained? I.e. where did you push that change?
| |
| 07:57 | <stgraber> bzr+ssh://bazaar.launchpad.net/~stgraber/ltsp/ltsp.lucid/
| |
| 08:04 | <alkisg> Thanks, got it. So each package maintainer maintains his sources... I was under the impression that there would be a "master archive" or something, with all the ubuntu package sources in it! :D

| 10:16 | <epaphus> Hello, does LTSP work with softphones that use USB head sets?
| |
| 10:16 | (thin client)
| |
| 10:16 | FGXR6 has quit IRC | |
| 10:18 | <vbundi> I think it might
| |
| 10:19 | you can get it to work in ubuntu (without ltsp) right?
| |
| 10:21 | epaphus: I think this might work... boot up your machine with the headset plugged in (not sure if this is required or not yet), log in to your LTSP server, and see if you get any sound out of your headset (ie login sound)
| |
| 10:21 | <epaphus> vbundi, right.
| |
| 10:21 | i think the softphone will be a localapp though
| |
| 10:21 | would it work like that?
| |
| 10:22 | <vbundi> epaphus: if you do not hear anything.. right click and go into your sound preferences on your gnome panel at the top, you can set which hardware device you want to use, and it should be in the list
| |
| 10:22 | epaphus: I think so? ;)
| |
| 10:23 | you could skip the above step and go right into twinkle or whatever you're using and see if your headset is a device in there....thats all it is really is a secondary sound device

| 10:48 | <infro> hello boys
| |
| 10:48 | I have a problem with k12linux
| |
| 10:49 | the client boot on network
| |
| 10:49 | but when I write username and password
| |
| 10:49 | I don't login
| |
| 10:50 | <sbalneav> Has your server's IP address changed lately?
| |
| 10:50 | <infro> I have static ip address
| |
| 10:50 | <sbalneav> You may need to do an ltsp-update-sshkeys && ltsp-update-image.
| |
| 10:50 | <infro> on my server
| |
| 10:50 | I have eth0 up on 192.168.0.1
| |
| 10:50 | <sbalneav> ssh package update? More blacklisted keys?
| |
| 10:50 | <infro> my client in the boot lease ip 192.168.0.10
| |
| 10:51 | <sbalneav> Well, regardless, I'd first start with the remedy I told you.
| |
| 10:51 | That's usually how to fix a non-logging in thin client.
| |
| 10:51 | <infro> I have digit ltsp-update-sshkeys on my server
| |
| 10:52 | <sbalneav> Have you also run ltsp-update-image?
| |
| 10:52 | <infro> yes
| |
| 10:52 | <sbalneav> Then I would check 2 things.
| |
| 10:52 | <infro> what's?
| |
| 10:53 | <sbalneav> 1) The ldm.log file on the thin client itself (You'll have to enable something like SCREEN_02 = shell to do it...

| |
| 10:54 | <stgraber> alkisg: well, technically anything in /etc/ is a conffile, IIRC only files outside of /etc should be declared explicitly
| |
| 10:54 | <alkisg> stgraber: My sch-scripts package was putting some info there - will that cause problems on updates?
| |
| 10:54 | I.e. I need to put IPAPPEND=3 and BOOTPROMPT_OPTIONS there...

| |

| |
| 10:57 | <alkisg> stgraber: but that only happens when there's been an upstream change to ltsp-update-image.conf, right? Not on "regular" ltsp updates with no changes to the conffile, even if the user changed it... right?

| 10:59 | <alkisg> stgraber: Hmmm I'm probably not making sense - let me rephrase that: if the user changes ltsp-update-image.conf, and a new ltsp version comes out, but the upstream ltsp-update-image.conf hasn't changed, will the user still be prompted? (sorry for asking too many questions :))
| |
| 11:00 | <sbalneav> infro: Depends on where your distribution puts it
| |
| 11:00 | That's why I posted a link to the upstream docs.
| |
| 11:01 | <infro> sbalneav: in my distribution, ltsp.conf it's empty
| |
| 11:01 | <sbalneav> You're running what? K12Linux?

| |
| 11:01 | Or an older LTSP4.2?
| |
| 11:02 | <infro> k12linux
| |
| 11:02 | I suppose LTSP5
| |
| 11:02 | <alkisg> Another question - would anyone mind / would there be a problem if we ran `chown $user:$group $LDM_SOCKET`, so that fat clients can reuse the ssh connection from inside the user session?

| 11:03 | <sbalneav> I'm not sure where Fedora puts the lts.conf file. I don't know if they put it in the tftp area, like Ubuntu/Debian, or not. I'd check Fedora specific LTSP docs. However, you'll need to put something in there like:
| |
| 11:03 | [default]
| |
| 11:03 | SCREEN_02 = shell
| |
| 11:06 | <infro> ok
| |
| 11:06 | I have find the lts.conf on fedora with locate
| |
| 11:06 | is't on tftp root
| |
| 11:07 | sbalneav: on screen_02 in this moment I have the shell
| |
| 11:08 | <sbalneav> ok, so try logging in via LDM, then have a look on screen 2, in the /var/log/ldm.log file.
| |
| 11:08 | see what ldm's unhappy about.

| |
| 11:28 | ssh does a reverse dns lookup of the client.
| |
| 11:28 | Are the clients listed in /etc/hosts?
| |
| 11:29 | <infro> on the server no
| |
| 11:29 | I add it?
| |
| 11:29 | <sbalneav> You should.
| |
| 11:29 | I would recommend you add /etc/hosts entries for all your thin clients
| |
| 11:30 | <infro> only on /etc/hosts on my server?
| |
| 11:31 | pmatulis has quit IRC | |
| 11:31 | <sbalneav> Either there, or in DNS, whichever is correct for your site.

| |
| 11:34 | <sbalneav> Then I'd suspect /etc/hosts would be fine.
| |
| 11:36 | <infro> The situation has not changed unfortunately ... we need more time with ssh
| |
| 11:38 | <sbalneav> Well, you'll need to fix that. That's the root of your problem.
| |
| 11:39 | <infro> there is the documentation of it?
| |
| 11:40 | <sbalneav> You have an ssh problem, so I'd expect openssh.org would probably be able to shed some insight.
| |
| 11:42 | <alkisg> Doesn't Fedora use a bridge on 192.168.0.x for the ltsp network?
| |
| 11:42 | <infro> alkisg: yes but I have put it down
| |
| 11:42 | it's a problem?
| |
| 11:43 | <alkisg> I don't know what else it configures on the network, but it might be something that affects you there
| |
| 11:47 | <thunsucker> infro: so your ssh is slow to respond?

| 12:49 | <vagrantc> Gadi_eeepc: so, i think the problems with cdpinger is specifically a problem with how qemu handles CDROM drives... it worked fine with virtualbox.
| |
| 12:50 | <Gadi_eeepc> vagrantc: hey, well thats good news!
| |
| 12:51 | * Gadi_eeepc is finding that virtualization is not being kind to ubuntu in several ways, too | |
| 12:52 | <vagrantc> i also need to test usb sticks on real hardware ... as i've been experiencing a bug where devices only show up in /var/run/ltspfs_fstab after boot. could also be just a qemu problem, but virtualbox-ose doesn't support usb, so i can't do the easy cross-reference with that...
| |
| 12:54 | i still would like to test the CDROM problem on real hardwre too...
| |
| 12:55 | <Gadi_eeepc> does anyone know if there is a known problem with xephyr on 64-bit karmic?
| |
| 13:02 | <vagrantc> stgraber: should i apply the last translation from the debian french translation team, or do you prefer to keep the translations as they are? http://bugs.debian.org/571073

| 13:09 | <stgraber> vagrantc: oh, sorry. Feel free to merge that one and I'll look at it afterwards. Not sure that'll make it in Lucid though
| |
| 13:10 | <vagrantc> stgraber: well, it's a bug reported against debian, so no problem. :)
| |
| 13:19 | ogra_cmpc has quit IRC | |
| 13:21 | <Lns> vagrantc: would you personally recommend using squeeze (amd64, though i'm confident it doesn't matter as much for debian) for a real world ltsp setup?
| |
| 13:22 | vagrantc: given it might be an educational environment with people wanting semi-recent packages
| |
| 13:22 | <vagrantc> Lns: it definitely introduces the possibility of something breaking every time you upgrade any of the many packages
| |
| 13:23 | <Lns> vagrantc: more than ubuntu? ;)
| |
| 13:24 | <vagrantc> at least ubuntu pretty much makes a release and doesn't introduce new upstream versions for that given release (?)
| |
| 13:24 | <Lns> true
| |
| 13:24 | <vagrantc> so you at least have 6 months of hopefully minimal changes...
| |
| 13:25 | <Lns> Reason I ask is that I'm exploring alternatives to ubuntu for ltsp. I've always used debian before ubuntu came out, and wonder what the biggest differences are regarding ltsp setups (say, ubu 9.10 vs deb squeeze)
| |
| 13:25 | <vagrantc> whereas major upstream version changes can wander into debian testing on a daily basis
| |
| 13:25 | <Lns> vagrantc: sure but they've at least been tested to some extent by the community, no?
| |
| 13:25 | <vagrantc> Lns: the backported ltsp stuff may actually work better on debian/stable right now than debian/testing...
| |
| 13:26 | <Lns> vagrantc: right on
| |
| 13:26 | vagrantc: then i'm just stuck with the older gui packages such as gnome, OOo, firefox, etc
| |
| 13:26 | <vagrantc> Lns: so if it's newer ltsp bits you need, i'd recommend using the backports...
| |
| 13:26 | * Lns sighs...grass is always greener | |
| 13:27 | <Lns> vagrantc: not so much latest ltsp, but at least localapps/fatclient stuff
| |
| 13:27 | <pem725> stgraber: I am setting up fat clients on my LTSP 5.2 install and some clients need windows. Do you (or anyone else) recommend running virtualbox as a local app? If not, any ideas how I can have my thin clients run windows?
| |
| 13:27 | <vagrantc> some of those are also available with backports ... though for the stuff you care about most, there still can be major changes on a semi-regular basis
| |
| 13:27 | <Lns> more what i'm worried about after that is the stability of gnome & friends
| |
| 13:28 | hmm
| |
| 13:28 | <pem725> BTW, I'm using Karmic at the moment with the PPA.
| |
| 13:28 | <vagrantc> pem725: use rdesktop to connect to a windows server (maybe virtual) remotely?
| |
| 13:28 | <pem725> does that work if I have multiple clients accessing windows?
| |
| 13:29 | <vagrantc> i don't really know windows.
| |
| 13:29 | <pem725> nor do I....
| |
| 13:29 | <vagrantc> but people talk about using rdesktop/RDP all the time, so i presume you must be able to have multiple connections to a single server (otherwise, what's the point?)
| |
| 13:29 | <pem725> true enough.
| |
| 13:30 | I will look into it.
| |
| 13:30 | <Lns> pem725: vagrantc: you can with terminal services, otherwise windows servers allow 2 simultaneous connections only
| |
| 13:30 | <pem725> thanks vagrantc.
| |
| 13:30 | ah
| |
| 13:30 | Lns: thanks for the tip.
| |
| 13:30 | <Lns> but you need CALs for each device (client access licenses)
| |
| 13:30 | <vagrantc> ooooh! two connections at once, it's amazing! :)
| |
| 13:30 | <Lns> =p
| |
| 13:30 | * Lns promises he will not get sucked into the windows flamefest | |
| 13:31 | <Lns> ...or start one
| |
| 13:31 | <pem725> so I guess I am stuck with either running multiple virtual machines with windows or setting up terminal services.
| |
| 13:32 | <Lns> pem725: what do you need windows for exactly?
| |
| 13:32 | <pem725> Lns: statistics packages that only run in Windows and cannot run in crossover or wine.
| |
| 13:32 | <Lns> ah
| |
| 13:33 | <pem725> if I could avoid windows I would.
| |
| 13:33 | <Lns> no i was just curious
| |
| 13:33 | <pem725> understood.
| |
| 13:33 | <Lns> but i concur ;)
| |
| 13:34 | <pem725> yeah, the mixed environments really make the LTSP setup complicated - more so than it needs to be.
| |
| 13:35 | <Lns> pem725: it's really not too bad when you have terminal services going
| |
| 13:35 | <pem725> unfortunately I don't have a stand-alone windows server. I would need to run windows as a virtual machine on my LTSP server.
| |
| 13:35 | <Lns> you just have to worry about all the MS stuff that comes with it
| |
| 13:35 | pem725: that's what i do
| |
| 13:36 | <pem725> hmmm
| |
| 13:36 | does it require more $$ other than the standard XP install?
| |
| 13:36 | <Lns> HAHHAHAHAHAHAHAHA yes.
| |
| 13:36 | <pem725> I am so far out of the windows world I have no clue.
| |
| 13:36 | I figured as much.
| |
| 13:36 | <Lns> well the CALs aren't too bad
| |
| 13:37 | i think...but the server license itself is a lot
| |
| 13:37 | plus you "get" to install terminal services license management server or whatever the frick that is
| |
| 13:37 | <pem725> my LTSP setup is in a university where we have a site license for XP and Win7 seats.
| |
| 13:37 | <Lns> so it's an added layer of complexity to make sure microsoft is getting their money
| |
| 13:37 | <pem725> ah
| |
| 13:37 | sounds like that is a non-starter for me.
| |
| 13:38 | <Lns> well if you have xp/7 licenses for free...
| |
| 13:38 | hmm.
| |
| 13:38 | <pem725> Lns: is there another option.....
| |
| 13:38 | you have me on the edge of my seat
| |
| 13:38 | <Lns> just trying to think, but i dunno. what kind of clients are you using?
| |
| 13:39 | can you have a local xp/7 install on a hdd?
| |
| 13:39 | <pem725> old P4's with 1GB and Gb NIC's.
| |
| 13:39 | <Lns> (not that i advocate that)
| |
| 13:39 | xp might not be too shabby on those, i dunno
| |
| 13:39 | <pem725> I could but these systems are not terribly stable as stand-alone computers.
| |
| 13:39 | as thin clients they work like a champ.
| |
| 13:40 | <Lns> +1 ltsp ;)
| |
| 13:40 | <pem725> they are old Dell's that overheat when the IDE bus gets too much traffic.
| |
| 13:40 | <Lns> ikes!
| |
| 13:40 | <pem725> yep
| |
| 13:40 | <vagrantc> stgraber: pushed the translation update... looks like it re-fuzzied a string... but otherwise (taking my lack of knowing french) looks like minimal changes.
| |
| 13:40 | <pem725> again, +1 LTSP!!
| |
| 13:40 | <Lns> well i might be wrong but maybe term services for windows is your only option if you want to really make it work
| |
| 13:41 | but of course that's $$
| |
| 13:41 | <vagrantc> running virtualbox or some other virtual machine as a localapp might be worth trying...
| |
| 13:41 | <pem725> vagrantc: I setup my fat client script to install virtualbox.
| |
| 13:42 | <vagrantc> although the ram requirements for windows + your windows app might be strained ... 1GB of ram on the clients?
| |
| 13:42 | <pem725> exactly...
| |
| 13:42 | <vagrantc> nothing like trying it out to know :)
| |
| 13:42 | <pem725> that is why I was hoping I could run it on the server some way...some how.
| |
| 13:42 | vagrantc: I got it working but it is so slow, it is unusable.
| |
| 13:42 | hence, my plea for alternative solutions.
| |
| 13:43 | any ideas how to run virtualbox on the server?
| |
| 13:43 | <Lns> pem725: and you're totally positive this software won't work with wine/cx?
| |
| 13:43 | <vagrantc> well, like any application, you can run it on the server if it's an application that doesn't need to be really responsive ... but multiple virtual machines on a server would require a really massive server
| |
| 13:43 | <Lns> pem725: how many people at a time need to access the software?
| |
| 13:44 | <pem725> Lns: yep. Tried to configure wine and had a contract with codeweavers but no luck.
| |
| 13:44 | <Lns> :(
| |
| 13:44 | <pem725> vagrantc: I have a pretty massive server. Dual Quad core with 32GB RAM.
| |
| 13:44 | massive for PC hardware that is....
| |
| 13:44 | <alkisg> Windows over AoE?
| |
| 13:45 | <pem725> alkisg: you mean running windows or ATA-over-ethernet?
| |
| 13:45 | <alkisg> Running windows over the network
| |
| 13:45 | <pem725> I have a coraid storage server.
| |
| 13:45 | <alkisg> This way you won't have any heat problems
| |
| 13:45 | And you can dual boot with LTSP if you want...
| |
| 13:46 | <pem725> whoa! ok, let me get this straight....
| |
| 13:46 | <alkisg> But 1 Gb RAM is a little to run vbox. You may do it with XP, but it won't be very fast...
| |
| 13:47 | <vagrantc> pem725: simply running virtualbox from the server might work ...
| |
| 13:47 | <pem725> so you can boot AoE?
| |
| 13:47 | <alkisg> http://winaoe.org/
| |
| 13:47 | <pem725> alkisg: thanks, I will look into the winaoe solution.
| |
| 13:48 | <alkisg> Or you could use vbox, giving 512 ram to XP and see how that goes...
| |
| 13:48 | <pem725> vagrantc: if I run windows on my server, how do I ensure that my thin clients get the proper kernel module?
| |
| 13:49 | whoops, I was a bit unclear with my previous note. If I run vbox on my server...
| |
| 13:49 | <Gadi_eeepc> anyone know what Classroom Control on Ubuntu is? (package: controlaula)
| |
| 13:50 | is it an italc replacement?
| |
| 13:50 | <pem725> alkisg: thanks for the winaoe link. Very interesting.
| |
| 13:50 | <alkisg> pem725: each PC will need its own copy, but copies should be easy to make... I've never done that though, I've just read about it.
| |
| 13:51 | Gadi_eeepc: it's an awful italc replacement
| |
| 13:51 | * alkisg is trying to make yet another italc replacement himself :D | |
| 13:51 | <Gadi_eeepc> so, what makes it awful?
| |
| 13:51 | <pem725> alkisg: individual copies for each client should not be a problem. I can clone them.
| |
| 13:52 | <alkisg> First, I couldn't get it to work. Second, on postinst it modifies a lot of /etc/* files and it doesn't restore them on postrm/purge
| |
| 13:52 | Third, it doesn't care much about security (that's from their site)
| |
| 13:52 | * Lns welcomes anyone to look at the current code for TCM and join the project if they so wish :) http://logicalnetworking.net/wiki/doku.php#projectthin_client_manager_tcm | |
| 13:53 | <alkisg> Fourth, it was designed for some local site needs, so it's a little weird in the things it needs...
| |
| 13:53 | pem725: in aoe, cloning = copying the image on the server. No need for ghost etc..
| |
| 13:53 | ogra_cmpc has joined #ltsp | |
| 13:54 | <pem725> alkisg: yup, that is why I really like the idea. very simple.
| |
| 13:54 | hopefully I don't need to maintain the windows support for too long.
| |
| 13:56 | <vagrantc> pem725: if you're running virtualbox on the server, the client doesn't need any modules... it will just display to the client.
| |
| 13:57 | <pem725> one final question before I start hacking away at my LTSP setup.....does anyone have specific recommendations to allow my fat clients full multimedia support through the browser? In other words, I would like flash, html5, java, etc. to be locally run and I need to know which packages to install in the ltsp-build-client.conf file.
| |
| 13:57 | <alkisg> Gadi_eeepc: if I have root access on a thin/fat client, is there any way to temporarily turn off the speaker (to prevent students from hearing songs etc)?
| |
| 13:57 | <pem725> vagrantc: really? I keep getting some error that the kernel module is not installed.
| |
| 13:57 | perhaps I need to look into the vbox setup before I abandon it.
| |
| 13:58 | <alkisg> pem725: ubuntu-resticted-extras should suffice
| |
| 13:58 | See the page I put on the ubuntu wiki...
| |
| 13:58 | <pem725> alkisg: excellent.
| |
| 13:58 | I'm going there now....
| |
| 13:59 | <alkisg> pem725: about the vbox error, try: sudo /etc/init.d/vboxdrv setup
| |
| 13:59 | <pem725> on the client or server?
| |
| 13:59 | <alkisg> Wherever the vbox is installed
| |
| 13:59 | <pem725> got it.
| |
| 13:59 | <vagrantc> pem725: using fat clients or thin clients? with fat clients, it would have to have that all set up on the client ... with thin clients, it should just be set up on the server.
| |
| 14:00 | <pem725> vagrantc: I had it setup on the clients but it was too slow. It also made the bootup so painfully slow that I decided to shift the load back to the server.
| |
| 14:01 | so now vbox will run from the server.
| |
| 14:01 | even with my fat clients.
| |
| 14:01 | <vagrantc> pem725: are the vbox modules loaded on the server?
| |
| 14:01 | <pem725> yep
| |
| 14:01 | <vagrantc> and you still get a module error?
| |
| 14:01 | <pem725> runs perfectly on the server.
| |
| 14:01 | yep.
| |
| 14:02 | at least I did with my previous install.
| |
| 14:02 | <vagrantc> it's possible virtualbox is stupidly written...
| |
| 14:02 | <pem725> vagrantc: I have no doubt that there are some strange things with vbox.
| |
| 14:02 | <vagrantc> if it messes with the machines video drivers or some such ...
| |
| 14:03 | <pem725> that might be the issue.
| |
| 14:03 | I am running some thin clients with Nvidia and others with the troublesome intel chipsets.
| |
| 14:04 | <vagrantc> pem725: your server have kvm support? you could use kvm/qemu-kvm on the server as well.
| |
| 14:05 | <pem725> vagrantc: I dunno. If KVM is enabled, I didn't enable it since I am using the stock Karmic server (pae) kernel.
| |
| 14:06 | <vagrantc> egrep '^flags.*(vmx|svm)' /proc/cpuinfo
| |
| 14:06 | ma_mu has joined #ltsp | |
| 14:06 | <vagrantc> pem725: it's another option if virtualbox proves to be problematic
| |
| 14:07 | <pem725> vagrantc: great idea.
| |
| 14:07 | yep, svm enabled
| |
| 14:08 | very cool; thanks for the additional options.
| |
| 14:10 | <ma_mu> is multiseat on a ltspclient possible
| |
| 14:10 | bobby_C has quit IRC | |
| 14:10 | <vagrantc> ma_mu: anything is possible... it might be more trouble than it's worth, though.
| |
| 14:11 | <vbundi> it's possible to hack the termserv.dll file to allow more than 2 concurrent connections on a windows XP machine
| |
| 14:12 | <alkisg> ma_mu: have you managed multiseat in a non-ltsp setup recently?
| |
| 14:13 | <ma_mu> no
| |
| 14:13 | <alkisg> Then, doing it in a thin client will prove more difficult..
| |
| 14:14 | I've tried multiseat 2 years ago in a non-ltsp setup, but it was too much trouble. And I think noone's done it with the new gdm...
| |
| 14:20 | <ma_mu> I tried another thing, virtualgl in ltsp
| |
| 14:20 | would be great in a diskless mythbuntu client
| |
| 14:20 | to play games on the client
| |
| 14:21 | ogra_cmpc has quit IRC | |
| 14:22 | <alkisg> Did it work?
| |
| 14:22 | ogra_cmpc has joined #ltsp | |
| 14:23 | <ma_mu> yes in smaller resolution like 1360x768
| |
| 14:23 | * alkisg wonders how many clients can a normal server support in this case, though.. | |
| 14:24 | <ma_mu> its a small home network with 4clients
| |
| 14:24 | and older hardware athlon 5600+ and geforce 7600gt
| |
| 14:25 | <alkisg> And e.g. googleearth worked on all 4 of them?
| |
| 14:25 | <ma_mu> not the same time
| |
| 14:25 | I should upgrade my hardware
| |
| 14:30 | I didnt try simultaneously on all 4 clients
| |
| 14:32 | <vbundi> virtualgl??
| |
| 14:32 | what's that like openGL for vbox etc?
| |
| 14:33 | <ma_mu> you can stream 3D apps to the client
| |
| 14:33 | <vbundi> interesting...
| |
| 14:34 | my machines do compiz effects and stuff.. and will render the GL screensavers.. although because they are not local they are quite slow
| |
| 14:34 | I was surprised at the performance either way... they're intel g915 graphics..
| |
| 14:35 | <ma_mu> doom3 on a client with geforce 7050 works here with virtualgl
| |
| 14:36 | and some wine games like tomb raider
| |
| 14:37 | <Gadi_eeepc> ma_mu: do you run the whole session through virtualgl or just launch virtualgl client as a local app?
| |
| 14:39 | <ma_mu> started the 3D app with vglrun -c proxy doom3 in a terminal not as local app
| |
| 14:40 | <Gadi_eeepc> ah - you may get even better performance if you run that command as a local app
| |
| 14:40 | *maybe*
| |
| 14:40 | <ma_mu> got no performance problems
| |
| 14:41 | <Gadi_eeepc> ah
| |
| 14:41 | great
| |
| 14:41 | what are you using as the graphics server?
| |
| 14:41 | just the server's video card?
| |
| 14:42 | <ma_mu> geforce grafik 7600gt on the server
| |
| 15:00 | pmatulis has quit IRC | |
| 15:03 | <vbundi> ma_mu: so graphics are rendered on the client or server then?
| |
| 15:04 | <ma_mu> on the server and stream to the client
| |
| 15:11 | <vbundi> what kind of FPS are you getting in Doom3 with a 7600gt?

| |
| 15:40 | <amnesia> well maybe u can help
| |
| 15:41 | <ma_mu> also tried max res but then a lot of flickering latency
| |
| 15:41 | <amnesia> I got the SuSE kiwi-ltsp ; some what ported it to slackware and I have the login screen via PXE
| |
| 15:41 | I type in user/pass, it says verifying with server ; then i get a no response from server
| |
| 15:41 | and it restarts the session, any ideas?
| |
| 15:42 | <vbundi> well if I screw up my credentials it does the same thing
| |
| 15:43 | so maybe it's not checking the password properly or something
| |
| 15:43 | <abeehc_> my clients will often put info to help with that in /var/log/ldm.log i think
| |
| 15:44 | <vagrantc> amnesia: you'll need to update the /opt/ltsp/i386/etc/ssh/ssh_known_hosts file
| |
| 15:45 | <amnesia> well i'm thinkin this is 5.2
| |
| 15:45 | or whatever
| |
| 15:46 | so srv/tftpboot/KIWI hosts?
| |
| 15:46 | <vagrantc> typically, you just run ltsp-update-sshkeys on the server.
| |
| 15:46 | not sure what kiwi-ltsp does.
| |
| 15:51 | <amnesia> well
| |
| 15:51 | im happy i got past the nfs server not responding

| |
| 15:58 | <abeehc_> i'm using 5.2
| |
| 15:59 | all the same i think kiwi-ltsp has their own channel
| |
| 16:03 | <vagrantc> kiwi-ltsp does things moderately differently than most of the other ltsp 5.x implementations

| |
| 16:56 | took like...2 seconds to rebuild the image
| |
| 16:56 | haha
| |
| 16:56 | <alkisg> Heh
| |
| 16:56 | Is there a way to temporarily turn off the sound volume for LTSP clients? (so that the students cannot turn it back on themselves)?
| |
| 16:57 | <Lns> hmm
| |
| 16:58 | alkisg: alsactl?
| |
| 16:58 | <alkisg> Lns, will that prevent the users from turning on the volume on their own?
| |
| 16:59 | <Lns> hrm
| |
| 16:59 | not sure if maybe you set the config file permissions..dunno if tha'ts updated dynamically, probably not
| |
| 17:00 | <alkisg> I thought of removing the students from the audio group temporarily, but they'd need to logoff for that to take effect... :-/
| |
| 17:01 | jammcq has quit IRC | |
| 17:02 | <Lns> either way you'd have to get into each booted client
| |
| 17:02 | <alkisg> That's the easy part :)
| |
| 17:02 | I've solved that with reverse connections to the server...
| |
| 17:03 | <Lns> nice! :)

| |
| 18:42 | about:plugins doesn't show it
| |
| 18:42 | <vagrantc> Lns: ltsp-update-image?
| |
| 18:43 | <Lns> vagrantc: :) did that
| |
| 18:43 | <vagrantc> just checking the obvious :)
| |
| 18:43 | <Lns> i'm going to do it again for good measure though ;)
| |
| 18:43 | <vagrantc> you could manually mount the image file to check that it's there
| |
| 18:43 | instead of rebuilding it
| |
| 18:44 | <Lns> it's ok, i'm having fun with the -n option :)
| |
| 18:45 | vagrantc: I have to say I tried Squeeze earlier..but grub failed to install. Being the lazy person I am I just gave up. I might try it later. :) I couldn't figure out why though.
| |
| 18:45 | well holy crap vagrantc I guess I didn't rebuild the image. =p~~ jeez.

| |
| 18:52 | BUT my java typing program seems to work. go figure
| |
| 18:54 | <vagrantc> heh
| |
| 18:55 | i'm testing debian-installer's squeeze ltsp-client-builder right now...
| |
| 18:58 | <Lns> woah...wait a minute. Has Ubuntu 8.04 --> 10.04 ltsp-update-image gotten significantly faster? I'm not using -n and it STILL built the image in like, 5 seconds.
| |
| 18:58 | meaning, nbd image building.. heh
| |
| 18:58 | <vagrantc> it is possible
| |
| 18:58 | <Lns> at least on my 8.04 server it took around 2.5 minutes
| |
| 19:02 | well i'm not complaining
| |
| 19:06 | <stgraber> Lns: if you are running today's ltsp >=0ubuntu3 on Lucid, -n is the default so no need to use it. If you want to check how long it would take without -n, you'll need to comment the line in /etc/ltsp/ltsp-update-image.conf
| |
| 19:06 | <Lns> stgraber: oh! Thanks :)
| |
| 19:06 | that's why.
| |
| 19:06 | and i guess i missed the whole point in the edubuntu meeting. =p
