wolfravenHello Room!  Can anyone help me with edubuntu resources.  I need good resources for developing a presentation to our Schools board of directors on why we should expose our students to edubuntu....03:17
wolfravenI am sure this wheel has already been invented several times and I really don't feel like spending too much effort reinventing it if someone can show me where the wheel yard is :)03:19
wolfravenWe are about to receive a large donation of computers and we are in the early stages of discussing our computer resource implementation plan and I feel we should utilize edubuntu for many reasons, just wonder if anyone knows links to presentations that will highlight those reasons.03:22

chris143installed 10.04 alternate CD but did not choose LTSP at install.. later I installed ltsp-standalone-server... all other client features work (localdev, video etc.) but no sound.. where should I look?06:51

Ahmuck-Jrhi. an alternative to using edubuntu in the classroom besides ltsp would be a private cloud?23:02
Ahmuck-Jrhi HedgeMage23:02
Ahmuck-Jrsbleavene around anymore?23:03
dgroos1Hi Ahmuck-Jr23:05
alkisgHe hasn't shown up for a long time23:05
alkisgToo much work, I guess...23:06
dgroos1Yeah, I was wondering about Scott as well.23:06
dgroos1Did he say adios or...?23:06
Ahmuck-Jrdid he leave after me?23:06
Ahmuck-Jrhi dgroos long time no chat23:07
Ahmuck-Jrsorta :)23:07
Ahmuck-Jrhas the edubuntu team looked at anything besides ltsp?23:07
dgroos1sometimes these things can be a bit too asynchronous...23:07
Ahmuck-Jrsuch as ldap/nfs, etc. combo or cloud ?23:07
alkisgTo satisfy what needs?23:07
Ahmuck-Jrwell, ltsp simply didn't work for us23:07
alkisgldap and nfs can be installed on edubuntu, sure... there are how-tos for that23:08
alkisgWhy not? I mean, what are your specific requirements?23:08
Ahmuck-Jrin edubutu, does it cover multiple stable setups?23:08
Ahmuck-Jralkisg: something that works :)23:08
alkisgltsp works for thousand of people23:08
alkisgMaybe your needs are different, but you need to state them if you want us to propose something to you23:08
dgroos1Ahmuck-Jr.  may I guess that it is the challenges of using LTSP on top of all the other challenges of using open source software in general or might I say technology in general?23:10
dgroos1...the problem solving never seems to end...23:10
Ahmuck-Jrhrm, i went through about 5 different machine configurations, and something didn't work quite correctly on each platform.  the next step was buy new machines, and that wasn't in the budget23:11
dgroos1on that note :) ... alkisg:  I've just got my computers set up and am testing sch-scripts...23:11
Ahmuck-Jrsound, SDL, video, firefox/flash, something23:11
alkisgAhmuck-Jr: well, if it's a hardware problem with linux (no drivers for specific hardware), then you'd need different hardware or OS, edubuntu doesn't have any drivers that linux doesn't already have23:12
dgroos1I can relate--wondering how to make sound work properly right now, but it isn't the challenge in front of me at this second...23:12
alkisgSo, if one standalone edubuntu installation doesn't work for you, there's no point in looking at nfs, ldap etc23:13
alkisgThat comes *after* the hardware is working23:13
Ahmuck-Jr_standalone worked great23:13
Ahmuck-Jr_it was through ltsp that it failed23:13
alkisgThen try fat clients, it's like standalone installations23:14
Ahmuck-Jr_sorry, i timed out23:14
alkisgWith central authentication + nfs23:14
Ahmuck-Jr_alkisg: like i said, another set of machines, not in the budget23:14
Ahmuck-Jr_but i have wondered about private clouds23:14
Ahmuck-Jr_and if anybody tried them23:14
dgroos1alkisg: can you help with this sch-script question?  I'm running sch-script on a client right now and tried to share a screen and got this...23:14
dgroos1sch-scripts error: XAUTHORITY is not defined23:15
dgroos1/usr/share/sch-scripts/scripts/server/runas-sudo-user: 1: cannot create /var/log/sch-scripts.log: Permission denied23:15
Ahmuck-Jr_seriously, i'm not here to bug about ltsp, but rather to find out if anybody has tried other "classroom" confiuraitons23:15
alkisgAhmuck-Jr_: I've tried fat clients, they work great for me. Boot in 13 seconds instead of 50 locally, and have nfs + cental authentication out of the box.23:15
alkisg(with ltsp)23:15
alkisgdgroos1: where are you seeing those messages?23:16
Ahmuck-Jr_thanks23:16
=== Ahmuck-Jr_ is now known as Ahmuck-Jr
alkisgAhmuck-Jr_: and, google earth, firefox, flash etc everything works fine, they're exactly like standalone installations23:17
dgroos1Ahmuck-Jr_ would it be helpful if there were an image of a server, basically all set up with just a few things to customize that already all the programs, NAT forwarding (pretty much) plugins installed, etc?23:17
Ahmuck-Jralkisg: i know it works for you.  didn't for me23:17
alkisgYou tried fat clients? That's lucid-only...23:17
Ahmuck-Jrnever bothered with lucid.  closed the ltsp lab by that point23:18
alkisgRight, that's what I'm saying, it's something new23:18
dgroos1That is what I would like, a huge disk image that I could use Clonezilla and blast it onto my server...23:18
Ahmuck-Jrlucid is pre-setup?23:18
alkisghttps://help.ubuntu.com/community/UbuntuLTSP/FatClients23:18
alkisgFat client support in ltsp was implemented in lucid, not before23:19
alkisgIt's an alternative to thin clients, a completely different model23:19
dgroos1alkisg: I see them on the terminal.  To start sch-scripts I typed in a client's terminal: sudo sch-scripts23:19
Ahmuck-Jrso anybody hear from Scott?23:20
alkisgdgroos1: so, you're using a thin client setup (with localapps), you have sch-scripts installed on the server and sch-client on the chroot, and run sch-scripts from a client, and get a xauthority error?23:21
dgroos1and when I do commands on the gui, there is output on the terminal.23:21
dgroos1hmmm... not sure if I installed sch-client...23:21
alkisgAre the clients autodetected?23:22
dgroos1YES!23:22
alkisg***before logging in to ldm***?23:22
dgroos1yes23:22
alkisgOK, then you have sch-client installed23:22
alkisgDoes lock screen etc work?23:23
dgroos1lock screen did, control did not.  Also, couldn't get the full name option to work.23:23
alkisgOK, let's take this one by one23:23
alkisg(you're not using our setup instructions, as they're specific to our setups, so you might be missing something)23:24
dgroos1sure23:24
alkisgDo you have x11vnc installed on the chroot?23:24
Ahmuck-Jralkisg: i hear your going for your masters?23:24
alkisg(it's installed automatically for us, it's on the sch-client "Recommends:" list)23:25
dgroos1not sure I'll check23:25
alkisgAhmuck-Jr: no, I got that already, I'm doing my phd currently (taken a leave of absense from teaching)23:25
Ahmuck-Jrah23:25
Ahmuck-Jrbtw, noticed greece was in trouble financially, how did that affect you?23:25
alkisgThey cut off about 200€ from our salaries... but after the EU ...loan (I don't know the word) it looks like it's going to stabilize now23:26
dgroos1I went to synaptic, typed in x11vnc and it says that it's installed...23:28
alkisgAhmuck-Jr: so, if standalone edubuntu installations are working for you, what more are you looking for? Ease of installation? Shared /home?23:28
alkisgdgroos1: no, not on the server23:28
alkisgHmmm wait23:28
alkisgThin clients, so yeah, on the server23:28
alkisgSo you're seeing the clients with thumbnails, and when you double click on them, you get that xauthority message?23:29
dgroos1Yes, also then.23:30
alkisgOK. Does teacher "broadcasting" works?23:31
=== Ahmuck-Jr_ is now known as Ahmuck-Jr
alkisg(showing the teacher screen)23:31
dgroos1I think I translated that as, 'share teacher screen' and it also doesn't work, giving the identical xauthority error23:31
dgroos1One thing is, I think that it things the teacher screen is the server and not the thin client I'm logged into.  Is that possible?23:32
alkisgIt may be, in our case the teacher is always sitting at the server. But I'm interested on fixing that, if that's a bug...23:33
alkisg(btw we just implemented a "create a bunch of users" feature, it'll be out in september)23:33
dgroos1cool :)23:34
alkisgdgroos1: if you run echo $XAUTHORITY, you do get something, right?23:34
alkisg(on the thin client, logged on as the "teacher")23:34
dgroos1In a new terminal I typed that in and a blank line was returned.23:35
alkisgThen there's something very wrong with your setup... hmm...23:35
alkisgLet me boot a thin client and compare..23:35
dgroos1You know, I'm also accessing the server via NX and tried to type in echo $XAUTHORITY and there too a blank line was returned...23:37
dgroos1And, I logged into the server via ssh as another user and got the same blank line returned...23:39
alkisgdgroos1: can you try closing sch-scripts, and running this?23:39
dgroos1ready... :)23:39
alkisgsudo XAUTHORITY=~/.Xauthority sch-scripts23:39
dgroos1it opens sch-scripts.  When I try to share-screen it give 4 lines of this: cat: /proc/2424/environ: Permission denied23:42
dgroos1then produces multitudes of lines of this: ** (vinagre:6541): WARNING **: Resolving failed: Timeout reached23:42
dgroos1forgot to mention, it opens a Remote Desktop Viewer window.23:43
alkisgOK, let me try running sch-scripts locally from a thin client (as opposed from the server), and I'll tell you in a while how that goes for me.23:43
dgroos1'k23:43
Ahmuck-Jrl8r23:44
dgroos1alkisg: I just went to the server (I've had the door unlocked) and tried sch-scripts on that and it didn't work like it had before.  I wonder if NX interferes with it?23:56
alkisgdgroos1: if problems happen, the sch-scripts sometimes needs restarting to get right again.23:57
alkisgNow problems happened because you run sch-scripts on a thin client, and the code wasn't ready for that23:57
dgroos1So... in other words, something has happened to my install as it used to work on the server, at least.  should I reboot the server?23:57
alkisgNo23:57
alkisgsudo restart sch-scripts23:57
alkisgBut you'd have to reboot the clients though23:57
alkisgI saw the problem, trying to get sch-scripts to run from a thin client...23:58
alkisg(it's not only xauthority, it's dbus too)23:59
