| 05:56 | <Edencampus> LTSP - Edubuntu 10.10 with Via C3 clients - clients unable to boot due to cx8 and cmov kernel requirements - any suggestions?
| |
| 05:58 | <elias_a> Edencampus: Yes - 10.04.
| |
| 05:59 | IMHO there's no way getting around that prob if you use 10.10.
| |
| 05:59 | <Edencampus> Bummer. I hoped I could rebuild the client kernel :(
| |
| 06:00 | Oh well, time for a big download. Thanks for confirming my suspicions.
| |
| 06:07 | Thanks for the input. Downloading 10.04 now. Pity about the new features in Edubuntu 10.10 - now unusable in many thin client labs.
| |
| 06:09 | <elias_a> Edencampus: It is a shame. However the reason is clear - for some reason support for Via C3, K6 and old i386 processors has simply been dropped.
| |
| 06:09 | On the other hand - it is nice that it was not done in the LTS version.
| |
| 06:14 | <Edencampus> True. At least we still have a couple of years of lts support.

| 09:23 | <robehend1> anyone had any kind of success with running virtualbox as a localapp? I have a few windows-only programs that I'm wanting to support, and rdesktop sadly wont work in this situation

| 09:55 | mikkel has joined #ltsp | |
| 09:56 | <highvoltage> robehend1: yep, I ran it as a local app and it worked just fine
| |
| 09:56 | <robehend1> what kind of client specs, can i ask?
| |
| 09:57 | <highvoltage> I can't remember the exact specs, it was some via machine with 1GB of RAM
| |
| 10:01 | <robehend1> hmm, alright
| |
| 10:02 | so, would it be possible to then, say, install it in the chroot, and set Screen_08 = virtualbox , so that my users could just hit ctrl alt f8 and have a windows login prompt? I understand I'd have to write the script for that to work, of course
| |
| 10:04 | tastle73 has joined #ltsp | |
| 10:05 | <highvoltage> yeah virtualbox needs an x session, of course, that doesn't sound ideal but I guess it can be done
| |
| 10:05 | <robehend1> is there a better recommendation? I'm trying to avoid them having to launch virtualbox, then launch the guest
| |
| 10:09 | gnunux has quit IRC | |
| 10:13 | <highvoltage> you could probably just have a session that launches the guest full screen, and when you close the guest it exits. that way you could just choose on ldm what you want

| 10:54 | <crazed> hm would it be possible to launch an ltsp image that is running a newer version of ubuntu than the server?
| |
| 10:54 | for example, i could launch 11.04 on my thin clients while the server is running 10.04

| 11:00 | <robehend1> crazed: hmm, not sure on that one. i'd think it would be, since the chroot is seperate than the server in many ways. maybe with fat clients?
| |
| 11:01 | <crazed> eh not really looking for fat clients though
| |
| 11:01 | mostly looking for the new ldm version
| |
| 11:01 | <robehend1> woudl it be possible to backport it from 11.04?
| |
| 11:02 | <crazed> hm possibly
| |
| 11:02 | <robehend1> i think, otherwise, you may run into dependencie hell
| |
| 11:12 | highvoltage: that'd work. do you think i'd be able to have 1 xp guest that all the users could use? I'm thinking for easy administration side.

| 11:58 | <highvoltage> robehend1: virtualbox can't do that
| |
| 11:59 | crazed: it's possible to connect to a newer application server than what your chroot is, yes. I think there's a limit to how for you can go back but I think 10.04 to 11.04 should be fine
| |
| 12:01 | <crazed> wait i'm confused, my application server would be running 10.04, but my thin client images would do 11.04
| |
| 12:01 | is that doable/

| 12:09 | <highvoltage> crazed: I haven't used that configuration before, and I believe LTSP clients don't work currently on 11.04, so it's likely that it won't work at this time
| |
| 12:09 | <Nubae> hmm sure they do, what do u mean they dont work?
| |
| 12:09 | <crazed> bah alright
| |
| 12:10 | <Nubae> oh wait 11.04, sorry misread, could be
| |
| 12:10 | <highvoltage> Nubae: they don't stop somewhere during the boot process and hang, I don't have all the details with me, stgraber said he's planning to look at it over the next week
| |
| 12:10 | s/don't//g
| |
| 12:11 | <Nubae> oh wow, so so much changed in natty?
| |
| 12:11 | <highvoltage> crazed: why would you want to do that anyway? do you need some hardware support?
| |
| 12:11 | <Nubae> highvoltage btw, I've been hired as lead dev for sugar server development in py/uy
| |
| 12:11 | <crazed> highvoltage: just for the new ldm version really
| |
| 12:11 | <Nubae> I'd love to know what's needed to get sugar working properly for ubuntu
| |
| 12:12 | dlezcano has joined #ltsp | |
| 12:12 | <highvoltage> Nubae: you should update us some time on what's going on in sugar, I've gotten quite out of touch with it
| |
| 12:12 | <Nubae> though we are concentraing on rhel6 for now
| |
| 12:12 | <crazed> the one in 10.04 spreads the screen across both monitors while the one in 11.04 will have your login in one monitor
| |
| 12:12 | <Nubae> s/conentraing/concentrating
| |
| 12:12 | <crazed> there was also some cool stuff about being able to login to an RDP session from ldm? i believe?
| |
| 12:13 | <Nubae> crazed thats been around for a while
| |
| 12:13 | <highvoltage> crazed: indeed, there might be a backport to lucid for that somewhere in a ppa...
| |
| 12:13 | <crazed> Nubae: it has? what is it known as, I kind of want to configure this
| |
| 12:13 | would allow us to use one system for all employees
| |
| 12:14 | <Nubae> highvoltage sure thing, let me know when the next edubuntu meet is
| |
| 12:14 | <highvoltage> Nubae: next wednesday, 20:00 UTC
| |
| 12:14 | <Nubae> crazed there was a lot of stuff done for persistent connections using rdp
| |
| 12:14 | meaning, if u get dropped physically by the network, u can reconnect and keep going
| |
| 12:14 | should be some howtos in the Ubuntu/ltsp wiki
| |
| 12:14 | <crazed> interesting
| |
| 12:15 | not quite sure what that entails
| |
| 12:15 | <Nubae> well, its one of the bennefits of using rdp
| |
| 12:15 | it should just be a ldm.conf value
| |
| 12:16 | X_SERVER=rdp or some such... check the docs
| |
| 12:16 | highvoltage cool, I'll try be there
| |
| 12:28 | <robehend1> highvoltage: ah, thought so. Darn. Was an idea, at least. now to think of another one to make this work

| 14:02 | * alkisg_debian waves back from his debian/lxde system ;) | |
| 14:02 | * vagrantc compliments alkisg_debian on an excellent taste | |
| 14:03 | <alkisg_debian> Unfortunately my laptop's nvidia card not longer works with the hair dryer... so I have to use the oven tomorrow :D
| |
| 14:04 | Baking the card at 200 °C for 20 min should do it, google says :)
| |
| 14:05 | <vagrantc> pfft
| |
| 14:10 | otavio has quit IRC | |
| 14:10 | <robehend1> oh gosh, dont do that
| |
| 14:11 | cards have heavy metals. heavy metals that can seep into your oven, causing toxicity
| |
| 14:12 | <alkisg_debian> I'll use an old oven that I had when I was in the university 20 years ago :)
| |
| 14:25 | <vagrantc> this doesn't seem like a sustainable maintenance effort
| |
| 14:28 | <robehend1> actually, it works nicely. if you get it hot enough, can soften the solder and allow the connections to reseat
| |
| 14:28 | or light on fire. one of the two
| |
| 14:30 | <alkisg_debian> I even saw a company while searching for new cards on ebay - they're "selling" their baking for 90 $
| |
| 14:30 | <robehend1> oh gosh
| |
| 14:30 | at least your video card isnt completely onboard in the laptop, so you dont have to bake the entire motherboard
| |
| 14:31 | <alkisg_debian> The bad news is that I can't find a suitable card for < 150$. The good news is that my laptop boots without the card, so I can use it as a headless ltsp server ;)
| |
| 14:32 | <robehend1> nice
| |
| 14:33 | i should look into picking up a laptop, since my old latitude has seen better days
| |
| 14:42 | say, is there a way to build a fat client based off of the edubuntu desktop? I like not having to install all the extra programs manually
| |
| 14:43 | cliebow has joined #ltsp | |
| 14:43 | <alkisg_debian> You mean like --fat-client-desktop=edubuntu-desktop?
| |
| 14:47 | tastle73 has left #ltsp | |
| 14:48 | <robehend1> i wondered if that was possible. :D
| |
| 14:49 | and, if i'm reading --extra-help correctly, if i happened to throw an edubuntu dvd into the cdrom before doing that, it'd pull the packages from there instead of the internet?
| |
| 14:50 | <alkisg_debian> Nope, it would need the packages in .deb format, not a live cd
| |
| 14:50 | <robehend1> ah. so still just use the package cache
| |
| 14:50 | <alkisg_debian> The alternate cd does have the packages in .deb, but not the edubuntu packages
| |
| 14:51 | <robehend1> no problem. just noticing that building a fat-client takes longer, as it should, of course
| |
| 14:51 | any difference between --fat-client and --fat-client-desktop ?
| |
| 14:51 | * alkisg_debian would like to make this scenario true in a later ltsp version: insead of ltsp-build-client, to open vbox, install edubuntu normally, and just install "ltsp-client" on top of it ==> fat client ready | |
| 14:51 | <alkisg_debian> --fat-client uses the DE of the server
| |
| 14:52 | <robehend1> ah, and you get to specify in --fat-client-desktop.
| |
| 14:52 | <alkisg_debian> Right
| |
| 14:52 | <robehend1> hmm
| |
| 14:52 | looks like its gonna be a fun weekend of redoing this ltsp server
| |
| 14:54 | alkisg_debian: mind if i pick your brain on something, ltsp related/
| |
| 14:54 | <alkisg_debian> shoot
| |
| 14:55 | <robehend1> well, our state-mandated testing software will only run on windows. so i was thinking of setting up vbox to run windows on the fat clients. getting vbox up and running is no problem. I'm just wondering if you know of a decent way to deploy the xp disk to users, so that they could use it.
| |
| 14:55 | I'm trying to avoid using microsoft terminal services due to licensing costs.
| |
| 14:56 | <alkisg_debian> Are you (license-wise) able to use the same XP installation for all users?
| |
| 14:56 | (a clone of it, of course)
| |
| 14:56 | <robehend1> i've got the licenses available.
| |
| 14:56 | <alkisg_debian> supposedly you need corporate for this
| |
| 14:57 | <robehend1> we're on the k-12 volume license agreement, with an alotted amount. no where near hitting it yet
| |
| 14:57 | <alkisg_debian> But anyway... well, you install vbox on the chroot and just have a script that creates a snapshot of a premade VM on boot
| |
| 14:57 | You could manually make those, but it's easier to have a script
| |
| 14:57 | <robehend1> agreed
| |
| 14:58 | and i thought of something like that. my only concern would be admistration of the snapshot, because if I'm not mistaken, each user would have their own, correct?
| |
| 14:58 | <alkisg_debian> + add shared folders for desktop, documents etc, +autologon with the same user account for everyone (as it runs on their account, no need to have many)
| |
| 14:58 | The snapshot could be deleted when vbox is powered off
| |
| 14:58 | <robehend1> hmm
| |
| 14:58 | <alkisg_debian> It's just so that they can all use a single "master disk"
| |
| 14:59 | ==> save hard disk space + administration time
| |
| 14:59 | <robehend1> thats where I was getting stuck, since vbox locks the disk while in use, if i'm not mistaken
| |
| 14:59 | <alkisg_debian> No, it doesn't, I've done it with vbox 4 yesterday
| |
| 14:59 | Booted 2 different XP installations from a single master disk
| |
| 14:59 | <robehend1> by pointing them both to the same .vmdk file?
| |
| 14:59 | <alkisg_debian> +1 different snapshot for each of those
| |
| 15:00 | No, the .xml file was pointing to the same .vdi file as the primary disk, and it also had a snapshot on top of it
| |
| 15:00 | <robehend1> ah, ok. that makes better sense then
| |
| 15:02 | guess i'm giong to have to take a look at this closer. would be quicker than waiting on the state to update the software
| |
| 15:04 | cliebow has quit IRC | |
| 15:05 | <alkisg_debian> I'd make a /usr/local/bin/VirtualBox script that calls VBoxManage and sets up the snapshot when a user launches vbox from the gnome menu
| |
| 15:06 | That way it would be completely transparent. Just dropping a script, and everything's ready.
| |
| 15:08 | <robehend1> that makes sense. i'm going to have to learn my vbox command line again it seems
