| stgraber | guillaume_: it's 01:42 at GMT+1 | 00:44 |
| LaserJock | he'll be on in the morning in Germany | 00:45 |
| guillaume_ | hehe allright | 00:45 |
| guillaume_ | I submitted the bug report | 00:47 |
| guillaume_ | https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/188223 | 00:48 |
| ubotu | Launchpad bug 188223 in ltsp "CHROOT will not upgrade" [Undecided,New] | 00:48 |
| LaserJock | I saw it | 00:48 |
| LaserJock | :-) | 00:48 |
| guillaume_ | k | 00:48 |
| guillaume_ | i was wondering if it was good practice to use the pastebin in a bug report | 00:49 |
| stgraber | no, not really | 00:49 |
| stgraber | usually you create a text file, then attach it to the bug | 00:50 |
| guillaume_ | is the pastebin reseted once in a while? | 00:50 |
| stgraber | some pastebin doesn't keep the history for long | 00:50 |
| guillaume_ | ok ill attach a text file then | 00:50 |
| guillaume_ | ok while i am here | 00:54 |
| guillaume_ | this bug was discovered while I was actually trying to make a LT2600 work with edubuntu | 00:55 |
| guillaume_ | I managed to make my wyse s10 work but the lt2600 still isnt working | 00:55 |
| guillaume_ | obviously like with most thin client, the xorg -configure doenst work | 00:56 |
| guillaume_ | so I have to point to a xorg.conf file in the the lts.conf file | 00:56 |
| guillaume_ | the wyse s10 and the lt2600 both use amd geode processor | 00:57 |
| guillaume_ | so specifying the amd driver solved it for the s10 but not for the lt2600 | 00:57 |
| guillaume_ | the lt2600 has a amd geode lx800 processor | 00:58 |
| guillaume_ | it just hangs when trying to start the xserver on the client | 00:58 |
| guillaume_ | screen goes black and keyborad stop responding | 00:58 |
| guillaume_ | I feel like I am talking to myself... | 00:59 |
| stgraber | sort of :) I'm busy testing the remaining ISOs for Alpha4 (to be released today) | 00:59 |
| guillaume_ | ok | 00:59 |
| guillaume_ | btw i tryed testing the alpha3 and it could not buil the ltsp chroot for some reason | 01:00 |
| guillaume_ | I only tried the 64 bit version | 01:00 |

| stgraber | is you chroot basedir a symlink ? | 01:12 |
| IsleVegan | is there an issue booting an ebox 3800 (via 800 mhz) from a dual processor amd64 x2 with edubuntu 7.10. the thin client gets an ip address via dhcp from one of the server's 2 ethernet cables then I get "pxe-t01: file not found" and then "pxe-e3b: tftp error - file not found" and then "PXE-M0F: Exiting Intel PXE ROM" | 03:23 |
| IsleVegan | this might be relevant: https://lists.ubuntu.com/archives/edubuntu-users/2006-August/000214.html | 03:24 |
| IsleVegan | ? | 03:24 |
| IsleVegan | should i do this: "sudo rm -r /opt/ltsp/amd64" and then this "sudo ltsp-build-client --arch i386"? does the amd64 folder need to be removed? | 03:38 |
| LaserJock | that would create a i386 chroot | 03:40 |
| IsleVegan | i'm new to ltsp / edubuntu | 03:40 |
| IsleVegan | i use ubuntu / xubuntu at home | 03:40 |
| IsleVegan | but this is new to me | 03:40 |
| LaserJock | and I don't do much with LTSP so I might not be much help :-) | 03:40 |
| IsleVegan | ok | 03:40 |
| IsleVegan | that's what this room is for, right? | 03:41 |
| IsleVegan | i have the ethernet cable going directly from the thin client to one of the server's ethernet ports, wasn't sure if that would work without a hub / switch or crossover cable between but if it gets a dhcp address i guess it's ok | 03:43 |
| IsleVegan | right? | 03:43 |
| LaserJock | actually, you could also ask the #ltsp channel | 03:57 |
| LaserJock | ahh | 03:57 |
| LaserJock | you need a switch or crossover cable | 03:57 |
| LaserJock | it won't work directly over a regular ethernet cable | 03:57 |
| IsleVegan | hmm | 04:08 |
| LaserJock | IsleVegan: I ran into that when I first tried LTSP | 04:12 |
| LaserJock | then I got a crossover cable and it worked | 04:12 |
| IsleVegan | well, it did get a dhcp address the way it is connected | 04:15 |
| IsleVegan | i don't have a crossover cable or switch here, just a router, and i'm not sure if the router can do that | 04:15 |
| IsleVegan | so, i'm trying it this way for now, until i can get a switch / crossover cable, i guess | 04:17 |
| IsleVegan | it booted up to the spinning gnome cursor | 04:33 |
| IsleVegan | saw the EDUBUNTU graphic | 04:33 |
| IsleVegan | now there is just the spinning cursor in the middle of the display, then a flash and a brief moment of the login screen then repeat | 04:33 |
| IsleVegan | and it's repeating continuously, like there might be a gui / x / gdm issue? | 04:34 |
| sickonnet | hiii | 04:44 |
| sickonnet | how to make support for printer on ltsp gutsy | 04:44 |
| LaserJock | IsleVegan: that could be. You might want to email edubuntu-users (you can find it on http://lists.ubuntu.com) | 04:49 |
| IsleVegan | ok, thanks, but you learned something too. that it is bootable when connected directly, possibly with the right hardware | 04:54 |
| IsleVegan | YAY :-) | 04:58 |

| Erik1 | i installed ubuntu desktop from a cd i burned from the dowload site of ubuntu. it installed ok and I added some stuff with synaptic. All this yesyerday evening. Now I boot up and my installation shows I have EDUBUNTU. what's the deal here ??? | 10:44 |
| === juliux_ is now known as juliux | ||
| Nubae | I have a silly question (maybe)... If I have a fat client environment (ltsp with whole edubuntu environment in it) can I update that environment via synaptic from the fat client itself... or does it have to be done in the chroot on the server? | 13:22 |
| laga | um. if you're using squashfs, you can't update it from the client | 13:27 |
| Nubae | yeah am, so how could I change it to so that is possible? | 13:31 |
| laga | you can change your client to boot from the chroot iself, eg export it over NFS. i think you can do that by setting an environment variable somewhere.. | 13:32 |
| laga | but to be honest, i wouldn't do that | 13:32 |
| Nubae | what I'm ideally looking for is, start up via ltsp from server with full ubuntu environment (local apps, devices, etc) but still be able to centrally manage... | 13:32 |
| laga | a) NFS doesn't work well with unionfs | 13:32 |
| laga | b) NFS is slower for booting | 13:33 |
| laga | IIRC | 13:33 |
| laga | what do you want to manage centrally? | 13:33 |
| Nubae | installations | 13:33 |
| Nubae | of apps, user management, etc... as much as possible really | 13:34 |
| laga | ah | 13:34 |
| Nubae | what about loading a generic part via squashfs and then the rest via nfs? | 13:35 |
| laga | well, why don't you just do that on the server and run ltsp-update-image? | 13:35 |
| Nubae | the machines are all the same | 13:35 |
| laga | how do you save files on the fat client, btw? | 13:35 |
| Nubae | memory stick, nfs mounted home | 13:35 |
| laga | ah | 13:35 |
| Nubae | but its not ideal yet... it works, but with many issues | 13:36 |
| laga | if my patches are accept for hardy, you'll be able to have a writable layer on top of the squashfs. well, actually, that's what's happening currently, but the changes are discared as soon as you reboot | 13:36 |
| Nubae | wow, that is cool indeed | 13:37 |
| laga | is does have its issues, too. eg you shouldn't run the package manager on the fat client or you'll run into issues as soon as you update the squashfs. | 13:37 |
| Nubae | yeah, its all new territory... | 13:38 |
| laga | Nubae: my suggestion for you right now is that you just chroot into the chroot, apply your changes, exit, and run ltsp-update-image | 13:38 |
| laga | that's cumbersome but the cleanest way i can think of | 13:38 |
| Nubae | thats what I currently do ;-) | 13:38 |
| laga | ah. | 13:38 |
| laga | disclaimer: i have never really used LTSP, i just hack it for fat client support | 13:39 |
| Nubae | oh cool, well I'm testing fat stuff a lot at the moment... | 13:39 |
| Nubae | I tried a full edubuntu-desktop apt-get but that didnt work out in the startup phases.... the init scripts freeze the startup | 13:40 |
| Nubae | so I tried a minimal install with a xfce desktop, and taht worked | 13:40 |
| Nubae | authenticating via ldap | 13:40 |
| laga | ldap? cool, never used that | 13:40 |
| laga | i suggest you search the wiki, there's a switch that'll let you use NFS | 13:41 |
| === ebel_ is now known as ebel | ||
| Nubae | I'm just working on a fat client howto... I'll show you when its done, maybe you can advise me on what should be changed | 13:42 |
| laga | but be warned, it's likely that it'll break unionfs with the current gutsy kernel. it should be fixed in the kernel that currently is in gutsy-proposed. | 13:42 |
| Nubae | I'll do that... | 13:42 |
| laga | Nubae: um | 13:42 |
| laga | Nubae: never mind. even if you use NFS; you'll still not be able to commit changes. i think | 13:42 |
| laga | not with unionfs on top of that | 13:42 |
| Nubae | its not that important... I was just wondering... | 13:42 |
| Nubae | apt-getting the chroot is easy enough | 13:43 |
| laga | yup | 13:43 |
| Nubae | i just hate having to build the image every time | 13:43 |
| Nubae | sometimes teh changes are so minimal | 13:43 |
| laga | Nubae: my "fat clients" are really just media centre pcs (mythtv frontends for mythbuntu), so it's a lot less complicated | 13:43 |
| laga | Nubae: i hear ya. | 13:43 |
| laga | i love it when i run ltsp-update-image instead of ltsp-update-kernel, too :/ | 13:44 |
| Nubae | so how are your clients fat, just kernel and module changes? | 13:44 |
| laga | Nubae: "fat" means, by my definition, that the client does all the work | 13:45 |
| laga | eg video display | 13:45 |
| Nubae | yeah right, local apps and local devices | 13:45 |
| Nubae | so you installed the entire edubuntu-desktop successfully in the chroot? | 13:46 |
| laga | no. i installed mythbuntu-desktop. :) | 13:46 |
| laga | i created a plugin for ltsp-build-client | 13:46 |
| laga | based off the kiosk mode | 13:46 |
| Nubae | ah ok, I'm not sure what mythbuntu is | 13:47 |
| laga | http://codebrowse.launchpad.net/~mythbuntu/mythbuntu/mythbuntu-diskless/annotate/laga%40prometheus-20080202002313-zpo3cpwwduycc4iy?file_id=30mythtv-20080117192245-pp5zhqeqyyhjciwx-1 | 13:47 |
| laga | Nubae: a HTPC distribution based on ubuntu and mythtv | 13:47 |
| laga | Nubae: think tivo on steroids | 13:47 |
| Nubae | ah, and you autologin so no need for authentication? | 13:48 |
| laga | kind of | 13:48 |
| laga | i created a --mythbuntu-copy-user-credentials switch which just copies user and password from the user running ltsp-build-client | 13:49 |
| laga | you can also just pass in a password using --mythbuntu-user-credentials user:pass | 13:49 |
| Nubae | hmmm... you're script is a good base for other fat environments | 13:50 |
| laga | thanks. as i said, i just added stuff to the kiosk mode :) | 13:51 |
| laga | Nubae: what's still missing are the changes i mentioned earlier to have a persistent copy-on-write branch to preserve files over reboots | 13:51 |
| Nubae | so on startup, what do you not boot from ltsp-client-core? | 13:52 |
| laga | you mean what i'm not using from it? | 13:52 |
| Nubae | yeah, did u blacklist anything? | 13:52 |
| laga | i don't remember what it does, i just remember i don't need it | 13:53 |
| laga | i think it sets up stuff like sound and local devices | 13:54 |
| Nubae | I run into problems with ltsp-client-core on startup... system freezes bootup process, but cant pin point exactly where | 13:54 |
| Nubae | just know its around the ltsp-client-core setup phase | 13:54 |
| laga | remove it temporarily and try again | 13:55 |
| laga | as you can see i removed it completely | 13:55 |
| Nubae | EARLY_PACKAGES="ltsp-client" - what does that do? | 13:56 |
| laga | it tells ltsp-build-client to install ltsp-client before most of the other packagres i assume | 13:57 |
| laga | i also added RC6_WHITELIST="reboot alsa-utils" because i don't want to be yelled at when volume settings are not preserved across reboots | 13:59 |
| Nubae | yeah, guess that makes sense... well, I'm doing this at the moment: sudo chroot /opt/ltsp/fati386 apt-get install edubuntu-addon-light gdm network-manager gnome-mount firefox openoffice.org | 13:59 |
| Nubae | that and ldap | 14:00 |
| laga | yeah, that works as well i suppose | 14:00 |
| laga | you just have all the ltsp-specific stuff still in there | 14:00 |
| Nubae | but somewhere between that and apt-get install edubuntu-desktop something breaks | 14:00 |
| laga | do you get a error message when booting or when installing? | 14:00 |
| Nubae | not installation wise, but trying to startup... I cant get to the error messages | 14:01 |
| Nubae | I took out quiet and splash from pxelinux.cfg | 14:01 |
| Nubae | goes through, almost to the end, and then just sits there... can't even login with root... | 14:01 |
| laga | remove the ltsp-client-core startup links in /etc/rc2.d/ and try again.. not sure if it helps. also get a backup so you don't break anything :) | 14:02 |
| Nubae | hehe, I have 3 fat chroot at the moment, all in various stages | 14:03 |
| Nubae | I tried moving the rc2.d ltsp-client-core startup up after gdm | 14:04 |
| Nubae | that didnt help | 14:04 |
| laga | do you actually need ltsp-client-core? | 14:04 |
| Nubae | well, haven't really thought about it, maybe, maybe not | 14:04 |
| Nubae | I'm gonna take a look at it... but still, I think its stopping before it gets to that | 14:04 |
| Nubae | whats the best way to test this, take out startup scripts from the runlevels? | 14:09 |
| laga | rm :) | 14:09 |
| Nubae | u mean mv ../someplaceforbackup/ | 14:09 |
| Nubae | :-) | 14:09 |
| laga | sure. | 14:12 |
| laga | %) | 14:12 |
| Nubae | well, you're script has given me some ideas... I'll start with a howto though... then move to a script :-p | 14:13 |
| laga | i'm glad it's helping you | 14:13 |
| laga | i hope i can submit my initramfs patches this weekend so you (I ;)) can have persistent directories for changes | 14:14 |
| Nubae | so what's your audience for this mythtv thing? | 14:14 |
| laga | everyone who uses mythbuntu ;)) heh | 14:15 |
| laga | it's for everyone who has a TV card and wants to have a powerful PVR to record things for him | 14:15 |
| Nubae | ah mythbuntu is a distro? | 14:16 |
| laga | it's also for people who want to have a complete media centre solution, eg it also has a UI to put on the TV | 14:16 |
| laga | yes | 14:16 |
| * Nubae is a little slow today | 14:16 | |
| laga | :) | 14:17 |
| Nubae | hmmm, I just took out ltsp-client-core and system freezes at Starting up log daemon | 14:17 |
| Nubae | I don't get it... I'm gonna have to document every detailed change and then rebuild the image until I get to what is doing this | 14:18 |
| laga | :/ | 14:19 |
| laga | maybe you can install a sshd | 14:19 |
| laga | and log in | 14:19 |
| Nubae | I've tried that, I can't even ping the machine when it gets to the freeze point | 14:19 |
| laga | :/ | 14:19 |
| laga | i wonder if that's caused by unionfs | 14:20 |
| Nubae | if I could log in as root i could check the logs | 14:20 |
| * laga tends to blame unionfs for everything | 14:20 | |
| Nubae | maybe, but why? | 14:20 |
| Nubae | hehe, yeah skapegoat is always good | 14:20 |
| Nubae | if there is a solution on the horizon | 14:20 |
| Nubae | :-) | 14:20 |
| Nubae | thats why I thought, startup with unionfs, then move over to nfs | 14:21 |
| laga | :) | 14:21 |
| laga | if it was unionfs, the new kernel in gutsy-proposed would likely help | 14:21 |
| laga | don't blame me if it doesn't help, though :) | 14:21 |
| Nubae | whats gutsy-proposed? | 14:22 |
| laga | if you check your /etc/apt/sources.list | 14:22 |
| laga | you can see it says things like http://some.mirror/ubuntu gutsy main restricted | 14:23 |
| laga | if you add another line saying "gutsy-proposed" instead of just "gutsy", you get stuff from gutsy-proposed. it contains packages which might eventually come into gutsy-updates once they're deemed stable enough. | 14:23 |
| laga | hint hint: they might break stuff :) | 14:23 |
| Nubae | righto, ok, didnt know that repository existed | 14:24 |
| laga | i'm assuming you're running gutsy. | 14:24 |
| Nubae | I'm gonna install alpha4 now anyway, so I'll test with that | 14:24 |
| Nubae | yeah I am | 14:24 |
| laga | not sure if alpha4 is fixed yet | 14:25 |
| Nubae | fixed? whats wrong with it? I have a recent daily build ogra told me is stable enough | 14:26 |
| laga | ah | 14:26 |
| laga | well, with regards to unionfs. if that ever was your problem, that is | 14:26 |
| * laga ponders | 14:26 | |
| * laga thinks hard | 14:26 | |
| Nubae | yeah sure gonna try it, I need a solution, because I have 21 dual core intel pcs with 2 gigs of ram sitting here running as ltsp thin clients | 14:27 |
| laga | not, that really shouldn't be the problem. unless you boot from nfs instead of squashfs | 14:27 |
| laga | haha :) | 14:27 |
| laga | nice setup | 14:27 |
| Nubae | yeah, the school has been moaning at me for a while now about this | 14:27 |
| Nubae | bandwidth lockups with multimedia, flash, shockwave | 14:27 |
| laga | :/ | 14:28 |
| Nubae | ah, and they are laptops, lol | 14:28 |
| laga | laptops.. school.. | 14:29 |
| laga | let me guess, they're chained to the desks? | 14:29 |
| laga | they computer lab at my school were a bunch of durons on VIA boards running win 98 or ME | 14:30 |
| laga | i often wished i could just raid the place with some ltsp ninjas | 14:30 |
| Nubae | yep chained indded | 14:32 |
| Nubae | they spent over 1000 euros per laptop, just to see them used as thin clients chained to desks | 14:33 |
| Nubae | bought because the 'looked good' | 14:33 |
| laga | it's not much better if they're fat clients chained to desks | 14:33 |
| laga | ouch. | 14:33 |
| laga | a used thin client + new LC display is like 300€ i guess.. | 14:34 |
| Nubae | I just bought 20 old p3 500mhz for 200 euros | 14:34 |
| Nubae | sorry 400 | 14:34 |
| Nubae | in total | 14:34 |
| laga | nice | 14:35 |
| Nubae | many companies are just trying to get rid of their older stuff and will even pay people to do it... I fantasised about starting a ltsp based company that did something with that | 14:35 |
| Nubae | u know, took from the rich and gave to the poor :p | 14:36 |
| Nubae | call it robinhoontu | 14:36 |
| laga | hehe | 14:37 |
| laga | i think there's something like that in the US... | 14:37 |
| laga | http://freegeek.org/ | 14:38 |
| Nubae | r u in the US? | 14:38 |
| laga | no | 14:38 |
| laga | germany | 14:38 |
| Nubae | ah, I'm in Spain myself... think it will be some time before something like that is possible here | 14:39 |
| laga | yup | 14:41 |
| laga | spain. </jealousy> | 14:44 |
| * laga goes out a bit :) | 14:44 | |
| Nubae | South of Spain even ; | 14:47 |

| markvandenborre | I have a bit of trouble with undisciplined users not closing down their sessions | 23:11 |
| markvandenborre | and load going up to > 10 | 23:11 |
| markvandenborre | the human approach doesn't seem to be working yet | 23:11 |
| markvandenborre | I wonder if it would be useful to kill all processes with uid > 999 every night | 23:12 |
| markvandenborre | no one is ever doing anything late at night | 23:12 |
| markvandenborre | or would you suggest other, more gentle stopgap solutions | 23:12 |
| stgraber | markvandenborre: you may want interested in xterminator, haven't used it though but it looks like what you are looking for | 23:20 |
| stgraber | https://edge.launchpad.net/xterminator | 23:21 |
| stgraber | s/edge\.// if you are not beta tester | 23:21 |
| markvandenborre | stgraber: will have a look | 23:31 |
| markvandenborre | the thing is it doesn't need a lot of idle users | 23:33 |
| markvandenborre | to make the load go up incredibly high | 23:33 |
| markvandenborre | idle or logged out ones | 23:33 |
| markvandenborre | so if 2 or 3 are still there, this one is not a solution | 23:33 |
| markvandenborre | 2 or 3 nautilus instances, I mean, because the load will go up to > 3, 4, 10 sometimes | 23:34 |
| markvandenborre | but thanks for the suggestion anyway | 23:34 |
| markvandenborre | ! | 23:34 |
| markvandenborre | (btw, this is rather beefy hardware, dual quadcore xeon with 4Gb of ram and 15k rpm hardware raid 5 disks | 23:35 |
| markvandenborre | ) | 23:35 |
| markvandenborre | so that's not the problem either | 23:35 |
