| nentis | anyone get an ebox-2300sx to work with ltsp? | 00:41 |
|---|---|---|
| nentis | this device is killing me. no math co-processor.. no amount of kernels seems to work. | 00:42 |
| lns | wow...back to the 386-sx days! no math coprocessor....WHY GOD, WHY?! | 00:44 |
| nentis | :( | 00:44 |
| lns | and i always wondered what the SX-2 series was supposed to be....twice the non-existent math co processor?? | 00:44 |
| nentis | double the clock speed? | 00:45 |
| nentis | I'm not happy that I may have 50 paper weights and 0 thin-clients. | 00:46 |
| lns | you should have gotten 1 and tested it.... ? | 00:46 |
| nentis | the 2300 (non SX) tested fine. | 00:46 |
| nentis | but yes | 00:46 |
| lns | never used an ebox myself | 00:47 |

| Meshezabeel | how can I get gcompriz to go full screen so that gnome panels are not in the way? | 04:26 |
| Meshezabeel | gcompris | 04:26 |
| johnny | add the lil sliders to the panel so you can hide them | 04:38 |
| johnny | that's about the best you can do until the app itself does it | 04:39 |
| Meshezabeel | ok, thanks, was hoping for a bit easier way for my kindergarten students, but guess I'll just have to put up with it for now ;) | 04:43 |
| johnny | well submit a feature request to run it full screen | 04:43 |
| johnny | but if that's the only app you're using.. you could make the session run it full screen | 04:43 |
| johnny | and not have gnome loaded at all | 04:43 |
| Meshezabeel | well, it does have a full screen option, it just doesn't seem to work for me | 04:43 |
| johnny | sounds like a bug | 04:44 |
| johnny | you're gonna have to talk to them | 04:44 |
| johnny | i guess | 04:44 |
| Meshezabeel | ok, thanks | 04:44 |
| Burgundavia | johnny: gcompris can full screen | 07:30 |
| johnny | yeah.. he just said it didn't work | 07:32 |
| Harrison___ | Hi I wonder if someone can help me. I'm 12 years old and have installed edubuntu on a laptop. If I can get it working, then I can use the laptop. However I'm stuck. if I enable the restricted driver, I get composite extension not available. if I disable it, I get desktop effects could be enabled...can someone please offer some help? as the forums seem to ask you to do one or the other | 08:14 |
| Harrison___ | and as i've done both, I seem to be stuck between 2 errors | 08:14 |
| Harrison___ | it's edubuntu 7.10 | 08:14 |
| Harrison___ | or is there a better channel to ask the question in? | 08:15 |
| nentis | your hardware might not support the special graphics | 08:19 |
| nentis | if an intel video card | 08:19 |
| nentis | you might ask in #ubuntu | 08:19 |
| nentis | gotta run | 08:19 |

| joe__ | anyone alive? | 13:07 |
| Harrison___ | graphics card is an ati radeon xpress 200m does this support desktop effects, it is supported by the restricted driver | 13:11 |
| joe__ | Anyone know how to manage users in edubuntu? | 14:07 |
| RichEd | joe__: same as ubuntu ... have you looked for help on help.ubuntu ? or the wiki ? | 14:10 |
| joe__ | Hmm... I think I just need to keep playing. | 14:10 |
| joe__ | I find users created on the server do no propagate to the clients. | 14:10 |
| ogra | there are no users on clients | 14:11 |
| joe__ | will 7.10 clients work on 7.04 server? | 14:11 |
| ogra | (teh client sessions run on the server, the server needs the users ) | 14:11 |
| ogra | no | 14:11 |
| joe__ | hmm. | 14:11 |
| ogra | the whole design of servige the rootfs has changed between 7.04 and 7.10 | 14:12 |
| ogra | *serving | 14:12 |
| joe__ | cool. | 14:12 |
| joe__ | I am trying to get this elementary school lab running (the guy who set it up is gone) | 14:13 |
| joe__ | some are edubuntu, some are ubuntu, all seem to be connected to the server. | 14:13 |
| laga | hey guys :) i suspect some people in here are using diskless clients. i'd like to add support for diskless clients to mythbuntu but i'm encountering an odd issue: no matter what i do, nfsmount inside the initramfs will always mount the root share read-only. is that normal behavior? | 14:21 |
| joe__ | Hey guys -- is it possible to run a lab with *some* clients diskless and others not? | 14:25 |
| ogra | laga, yes | 14:25 |
| laga | ogra: do you know why that happens? | 14:26 |
| ogra | laga, thats the dsign :) the clients boot with the writable bits in tmp ... its a security thing since theer is nothing running on the client thats not actually needed to connect to the server and execute a session there | 14:28 |
| ogra | s/in tmp/in a tmpfs/ | 14:29 |
| ogra | sorry | 14:29 |
| ogra | the clients have no users or anything, all tehy do is boot into a login manager that then starts an ssh session to the server where it executes a session | 14:29 |
| laga | ogra: from what i've read in the ubuntu wiki, that's your (edubuntu) design. however, the initramfs script provide the facilities to mount the nfs root writeable. | 14:29 |
| ogra | right | 14:30 |
| ogra | but i wouldnt suggest that | 14:30 |
| laga | ogra: i will not use your scripts (sorry if i made it sound like that), i was just wondering if anyone has made experiencies similar to mine | 14:30 |
| ogra | there are many files that get changed at every boot | 14:30 |
| laga | ogra: i'll be using unionfs with that, no worries. | 14:30 |
| ogra | if you have more than one client it will break | 14:30 |
| ogra | we use unionfs | 14:30 |
| laga | my problem actually is that i can't mount any shares rw in initramfs. but the root share would be a good start. :) | 14:31 |
| ogra | (we dont use nfs anymore since gutsy since that had massive speed probelms) | 14:31 |
| ogra | you dont want root to be writable trust me :) | 14:31 |
| laga | yes, you use unionfs in gutsy. with nbd and squashfs, which is a really nifty approach :) just discovered that a few minutes ago | 14:31 |
| ogra | you can create an fstab in the squashfs image to mount diffferent shares easily | 14:31 |
| laga | ogra: i do not want root to be writeable. i just want to be able to mount a nfs share rw. | 14:32 |
| ogra | i'd rather suggest that | 14:32 |
| ogra | right | 14:32 |
| ogra | make sure nfs-common is installed in the image | 14:32 |
| ogra | (its not in the default ubuntu bootstrap selection anymore, so not installed on thin clients) | 14:33 |
| laga | thanks, but i don't want to use squashfs. :) i was just wondering if anyone was unable to mount nfs shares rw in the initramfs that comes with ubuntu. | 14:34 |
| ogra | everyone | 14:34 |
| ogra | (as i explained above, no nfs client bits are in the image) | 14:34 |
| ogra | your mileage will vary if you want to use ltsp without squashfs though | 14:35 |
| ogra | its what we default to since a while | 14:36 |
| laga | thanks. | 14:38 |
| ogra | and the old nfs chroot might go away in hardy, not sure yet | 14:38 |
| ogra | we currently keep it for easier maintenance of the image | 14:38 |
| laga | i should have made it clearer that i didn't even want to use ltsp in the first place :) | 14:38 |
| ogra | but there is an image shell that makes it possible to drop the 400M of cruft | 14:38 |
| ogra | well, it would be cool if you could integrate it in ltsp :) | 14:39 |
| ogra | i was planning a myth mode myself since quite some time .... given that its likely only a five line pulgin that would be needed it shoudl be fairly easy | 14:39 |
| laga | yes, but we need fat clients :) | 14:39 |
| ogra | why ? | 14:40 |
| ogra | you need a player and a frontend to the db server, no ? | 14:40 |
| ogra | (at least thats how i always understood mythtv) | 14:40 |
| laga | back then, a few years ago, i wanted to add mythfrontend to LBE. i failed horribly. :) | 14:40 |
| ogra | which means two additional package to install and probably some tweaks to the ltsp defaults | 14:40 |
| laga | ogra: mythfrontend ( = player software) needs to be run as local app. | 14:40 |
| ogra | right | 14:41 |
| ogra | so you should actually be able to just install the mythfrontend package in the chroot and thats it | 14:41 |
| ogra | have you ever looked at ltsp plugins ? | 14:41 |
| laga | how do you run local apps in ltsp these days? back then, you had to do ssh magic | 14:41 |
| ogra | https://wiki.ubuntu.com/HowtoWriteLTSP5Plugins | 14:42 |
| ogra | we dont have localapp support ready yet for ltsp5 | 14:42 |
| ogra | but the approach is to use xatoms and on the session side some xdg overlays | 14:43 |
| ogra | ldm makes that pretty easy | 14:43 |
| ogra | since we just need to send the data through the ssh tunnel ... | 14:43 |
| laga | excuse my ignorance. what does "ldm" stand for? | 14:44 |
| ogra | ltsp display manager | 14:45 |
| ogra | the login manager used in ltsp5 | 14:45 |
| ogra | (we dont do xdmcp anymore) | 14:45 |
| laga | ah | 14:46 |
| ogra | ldm by default does: ssh -X user@server /etc/X11/Xsession | 14:46 |
| ogra | it also has a mode that omits -X and sets DISPLAY to the clients display .... so you keep ssh password handling while having the speed of old XDMCP sessions | 14:47 |
| ogra | anyway, have a look at the kiosk plugin described on that wikipage ... its running a local firefox (teh code is buggy though, its just a rought example) ... seems similar to what you want | 14:48 |
| laga | https://wiki.ubuntu.com/LTSPFatClients?highlight=%28ltsp%29 <- i suppose this has not been implemented yet? | 14:49 |
| ogra | (replace ff with your mythfrontend, add nfs-common to the chroot ... | 14:49 |
| ogra | nope | 14:49 |
| laga | sad | 14:49 |
| ogra | it depends on a network auth mechanism we dotn have | 14:49 |
| ogra | with the new squashfs/unionfs architecture it should be trivial though | 14:50 |
| ogra | (to do it yourself) | 14:50 |
| laga | true | 14:50 |
| laga | how big is such a squashfs image compressed/uncompressed? i kinda liked the idea of using the server's / | 14:51 |
| ogra | the nfs implementation would have been tricky though .... sicne nfs and unionfs in ubuntu dont like each ther you would ave to do a lot of bind mounting etc | 14:51 |
| laga | (read-only, of course. i'm not insane :)) | 14:51 |
| ogra | -rwxr--r-- 1 root root 158M 2007-12-29 17:47 i386.img | 14:52 |
| laga | oh, what's the matter with nfs and unionfs? i know there's some special handling for nfs in unionfs but i think i've read it's not necessary anymore in recent kernels | 14:52 |
| laga | sounds sensible | 14:52 |
| laga | although we probably have to add 100M (uncompressed) for mythtv | 14:52 |
| ogra | well, it didnt work in gutsy, nfs/unionfs just broke back then | 14:52 |
| ogra | since we stepped away from insecure nfs completely in ltsp upstream i didnt look since gutsy started | 14:53 |
| laga | unionfs was broken badly earlier in gutsy but it's been working fine since the release | 14:53 |
| ogra | not to mention that nfs is about 5X slower in booting than the nbd/squashfs/unionfs combo | 14:54 |
| laga | how long does it take your clients to boot into X? | 14:55 |
| ogra | 50-70sec depending on the client (nothing faster than 1GHz here, max 128M) | 14:57 |
| laga | sounds good enough. | 14:58 |
| ogra | with nfs that went above 2min for some | 14:58 |
| laga | i'd expect that more RAM would speed that up a bit. and running a mythtv frontend in 128M is silly (yet i do it and wit works reasonably well) | 14:59 |
| ogra | yeah, 256 would be minimum i guess | 14:59 |
| laga | 512M would be better. DDRII-RAM is cheap enough if you buy a new box. | 15:00 |
| laga | ogra: you almost convinced me. :) i suppose i could ask one last question: do i _need_ a dhcp server? many epople will already have SoHo-routers with their own dhcpds. for our first attempt at netbooting in mythbuntu 8.04, i was just going to create a simple script which created a bootable usb pen drive/CD-ROM where the bootloader would pass all necessary options like nfsroot=10.0.0.1:/ and ip=dhcp. would that still be possible with ltsp? | 15:03 |
| ogra | you need a dhcp server to hand out the boot info | 15:04 |
| ogra | ltsp has two server packages | 15:04 |
| ogra | ltsp-server and ltsp-server-standalone | 15:04 |
| ogra | the latter depends on dhcpd3 | 15:04 |
| laga | yeah, ltsp-server-standalone comes with a dhcpd. | 15:04 |
| ogra | if you dont use a local dhcpd you need to set up the other in the right way to serve the tftp info | 15:04 |
| laga | well, tftp is just used to download kernel + initrd, right? | 15:05 |
| ogra | edubuntu uses a two NIC install by default for its server ... that way one NIC can be dhcp client at a ruter and the second serves the TC network (including a dedicated dhcpd) | 15:05 |
| laga | let me guess: if i want to use one NIC, i need to add an IP alias to that interface? | 15:06 |
| ogra | no | 15:07 |
| ogra | if you want one NIC you need to make sure there is no other dhcpd in your network or configure that one correctly for netbooting | 15:08 |
| laga | let's see: dhcp to tell the PXE stack to download pxelinux, pxelinux then downloads its config file and loads kernel + initrd, right? is it used for anything else? | 15:09 |
| ogra | well giving out the IP :) | 15:11 |
| ogra | but yes thats about it | 15:11 |
| ogra | ther is tftp involved in some pieces :) | 15:11 |
| laga | ok. let me replace tftp by putting the bootloader, the kernel and the initrd on a usb pen drive. | 15:12 |
| laga | now we just need the dhcpd. assuming i can just pass in all needed options as a boot option for the kernel/initramfs, i should be fine. | 15:13 |
| laga | i guess i need to look at your scripts | 15:13 |
| laga | thanks a lot, you have beena great inspiration! | 15:13 |
| laga | ogra: just looked at your initramfs scripts. is there any reason why you're (seeminglxy) duplicating work in init-bottom/unionfs_cow and scripts/ltsp-nbd ? | 15:34 |
