I've a client that doesn't boot! screen stopped after filename : /ltsp/i386/nbi.img
01:58gsouque has quit IRC
02:04dobber has joined #ltsp
02:09
<muppis>
Uzzi, you should fix your dhcpd.
02:10
Uzzi, as clients do not use nbi.img file and it's incorrectly offered to client by dhcpd because missing or incorrect header in dhcp request made by pxe.

<Uzzi>
other clients works fine
02:17
<muppis>
Maybe different nic ?
02:17alkisg has quit IRC
02:18
<Uzzi>
yes
02:18
<muppis>
:)
02:24
<Uzzi>
then what should I do?
02:26
Ive dhcp3 server and ltsp server in two different server
02:32
<muppis>
At /etc/ltsp/dhcpd.conf you should find if else -statement. Remove/comment that, so only correct file stays there.
02:35
Ah, put your used dhcpd.conf to pastebin, so I fix it for you.
02:36
<arvin_>
Uzzi: sorry that's probably my fault.
02:37
muppis: he can't boot etherboot devices, so I gave him a suggestion.
02:37
muppis: check it out and you'll see what I mean.
02:38
<muppis>
arvin_, ah. Didn't know that.
02:38
<arvin_>
muppis: drbl uses that very same vendor name string to qualify etherboot machines.
02:38
<muppis>
arvin_, ok.
02:39
<arvin_>
This is what I gave him: http://ltsp.pastebin.com/tF56ZmXZ
02:39
Something is probably wrong in the if statement.
02:40
<muppis>
Afaik, whole statement isn't really needed, if not known to need. So this should be fine: http://ltsp.pastebin.com/jDGQzQmU
02:41
<moobyFR>
I had some devices which didn't claim PXEClient in the option vendor-class-identifier, and weren't able to use the nbi.img.but they could handle pxelinux.0
02:42
<arvin_>
muppis: wouldn't that rogue with the assumed existing DHCP?
02:42
muppis: this is how they solved it in DRBL (to avoid rogue DHCP:ing) http://ltsp.pastebin.com/PSvyfpuT
02:43
moobyFR: are you sure they were PXE and not etherboot?
02:44
<muppis>
arvin_, you got point in there. :)
02:45
<moobyFR>
yes sure
02:45
<Uzzi>
this in mine http://ltsp.pastebin.com/EFdxEhMc
02:46
<arvin_>
muppis: that drbl method works flawlessly by the way. I have yet to encounter any issues with that, and I've been running DRBL/Clonezilla for almost 1½ years now in production.
02:46
<Uzzi>
now with acer host give /ltsp/i386/pxelinux.o but doesn't boot arvin_ muppis
02:48
<arvin_>
Uzzi: you're defining two netmasks.
02:49
<muppis>
arvin_, ok. Haven't yet needed DEBL/Clonezilla, so didn't know their special needs.
02:50
DRBL..
02:50
<Uzzi>
my ltsp server is in 172.16.6.
02:50
other clients works fine with this dhcp.conf
02:54
<muppis>
Then it's about what that one sends in request.
02:54
Or doesn't send.
02:56
<Uzzi>
only this client doesn't work. grrrr
02:57
<muppis>
Uzzi, you can make a own pool by mac for that.
02:59
<Uzzi>
in my dhcp.conf i've fixed ip for this mac
03:02
<muppis>
Uzzi, try specify filename -option in same place. I don't really know does it work, but worht of try if nobody rule me over.
03:03
<Uzzi>
host acer { hardware ethernet 00:1c:25:3d:13:0a; fixed-address 172.16.1.140; filename "/ltsp/i386/pxelinux.0"; }
03:03
<muppis>
yes.
03:03
<Uzzi>
same error
03:04
i've just try it
03:06
<muppis>
How about greating a own group for it?
03:07
<arvin_>
muppis: When I took over as the local support at my job there were so many undocumented and homebrew (client integration) applications/solutions that it was impossible to do anything else than simply cloning the machines. Multicast cloning is extremely useful when you want to deploy 50 machines in 20 minutes. :)
03:08
<muppis>
arvin_ :D yesh, it would dead boring clone them one by one.
03:08
<arvin_>
muppis: I had to do that for 35 machines. It took me an entire weekend. That's when I decided "never more". :)
03:09
muppis: My problem is our god damn clients.
03:10
muppis: If they would have used MSI packages with standard instructions, I could have completed my unattended installation to make a fresh install automatically, rather than cloning the machines.
03:11
Though most applications are pre win2k even.
03:11
Solutions they used and never left because of the cost, when everything "works so fine already".
03:12
Yeah it works fine now, but when it doesn't you have to pay up for all those costs you ignored when you were encouraged to upgrade your god damn system.
03:17
Uzzi: did you fix your netmasks?
03:17
subnet 172.16.0.0 netmask 255.255.0.0 {
03:17
option subnet-mask 255.255.255.0;
03:17
Conflict
03:19
Change the first line to subnet 172.16.1.0 netmask 255.255.255.0 {
03:21
Uzzi: by the way, is there another DHCP in your environment?
03:21alkisg has joined #ltsp
03:21
<Uzzi>

03:21
but my ltsp server is in 172.16.6.50

<arvin_>
Uzzi: can you paste your ifconfig?
03:57
<Uzzi>
my ltsp server is 172.16.6.xyz, my dhcp server is 172.16.1.xyx and cliend have 172.16.1.xyz
04:01
<arvin_>
Uzzi: netmask?
04:01
Uzzi: so you are using another DHCP.
04:01
Uzzi: You're confusing me. :)
04:01
<gsouque>
does anybody know how to prevent users from shutting the server (on freenx)
04:01
<Uzzi>
dhcp server and ltsp derver are two machine
04:02
<arvin_>
Uzzi: The DHCP, is it a linux box?
04:02
<Uzzi>
yes
04:03
of course
04:03
<arvin_>
Uzzi: Did you make sure you've disabled DHCP in the LTSP?
04:03
<Uzzi>
yes
04:04evil_root is now known as zz_evil_root
04:04
<arvin_>
Uzzi: Ok good. Now change "option subnet-mask 255.255.255.0;" to option subnet-mask 255.255.0.0;
04:04
In dhcpd.conf
04:05
Uzzi: make sure you edit /etc/dhcp3/dhcpd.conf, since you won't have a /etc/ltsp/dhcpd.conf.
04:08
<alkisg>
gsouque: which DE? On gnome, the server doesn't shut down from the logout menu...
04:11
<gsouque>
i am using gnome and there is no pb with ltsp but with freenx users can shutdown the server
04:11
<Uzzi>
arvin_, I kannot change subnet!
04:12
But this isn't the true broblems, 7 clients works fine! only this
04:12
<arvin_>
Uzzi: you have to choose mate. Which subnet do you want to use 255.255.255.0 or 255.255.0.0.
04:12
Aha
04:12
Well that makes a difference.
04:14
Uzzi: what happens on the client when you try to boot it?
04:15
<alkisg>
gsouque: hmmm, I'm using neatx-server and when I select "shutdown" from an nx session I just get logged off
04:15
<Uzzi>
after filena: /ltsp eccccccccccc a splashy errore (se same in all clients) and after stop
04:15
<gsouque>
yes but it is not the case with freenx
04:16
<alkisg>
Strange
04:16
<gsouque>
i don't use neatx becouse somes command lines like nxserver --list or terminate don't ever exist
04:16
<alkisg>
gsouque: this isn't ltsp related though, so maybe you should try in some distro channel, e.g. #ubuntu etc
04:17
<arvin_>
Uzzi: I don't understand. Do you see this in all clients, but 7 of them work?
04:18
<gsouque>
yes thanks i ask here because users of this chan are good linux users !!! :)

Uzzi: ok, so next step, this client is PXE or etherboot?
04:56
<Uzzi>
pxe
04:57
<arvin_>
Does it work if you remove this: host acer { hardware ethernet 00:1c:25:3d:13:0a; fixed-address 172.16.1.140; filename "/ltsp/i386/pxelinux.0"; }
04:57
And set it as a "normal" client?
04:57
<Uzzi>
sis191 pxe
04:57
arvin_, just do it! same errors
04:58
<arvin_>
Can you paste your dhcpd.conf again?
04:58
You've probably updated it a bit by now.

ltspfs is for the server

I modified the modules.dep for resolving dependences but I always get the same error: WARNING: Module vboxdrv not found.

It can be the module is not in the correct path?

I instaled a virtualbox in the ramdisk of a thin client and copied a windows vm on its hardisk, and it runs!
12:55
<robehend1>
does it run well?
12:56
<joelgsm>
as a localapp
12:56
<robehend1>
hmm
12:56
i should look at that one day, in case I cant get this Testnav working on ubuntu

12:58
<robehend1>
ah
13:00
seems like your going to have to have some pretty beefy thin-clients to run a virtual xp though
13:00
<joelgsm>
I will setup windows terminal servers on virtual machines running on fat clients so that thin clients can connect to a windows aplication
13:02
So I will only setup one ltsp fat client and only one windows virtual machine for use in over 20 pc's (fats and thins)
13:02
<robehend1>
hmm
13:02shawnp0wers has quit IRC
13:02
<robehend1>
nice solution. though figuring out that ms licensing could be fun ;)
13:04
<joelgsm>
Almost computers have allreeady windows on its hardisk, but it easier to manage using ltsp and virtual machines
13:05
and a windows in a vm will not have virus
13:05
as in a sandbox ;-)

sorry, I should create the users in chroot of thin client?
15:11

hmm ok

So yeah, computer control is crucial and I must admit I'm at a rudimentary phase.

chroot /opt/ltsp/i386

#adduser user1?

right--just showing you that kids have the tool constantly in front of them as they are doing their experiment or doing an online simulation or whatever.

when you have 25-35 feisty students (not fawns ;)) in front of you, you need to be able to trust in your tools and italc just couldn't do that for me.
15:15
<robehend1>
yep
15:15
<dgroos_>
So, in steps alkisg (to a round of applause) with the Greek Solution.
15:16
They have a robust set of solutions for many thinks like updating the chroot/image, controlling/sharing the desktops,
15:16
<robehend1>
any central repository or documentation? I could probably adapt from that
15:17
<dgroos_>
logging out students or powering down clients.
15:17
That would be awesome!
15:17
<robehend1>
currently, i'm using a bastard child of Sabayon and some perl/python scripts running as cron jobs
15:17
its running how I want, but I'm creating a handbook to provide to other techs in the area, and knowing these folks, i need to make it idiot proof
15:18
<dgroos_>
Scott B did a great job resurrecting Sabayon, but soon after he left I had a few problems and couldn't get it to work properly.
15:18
<robehend1>
Gadi has helped me with sabayon, and has clobbered together a fix
15:18
i've had success with it, but limited so
15:18
<dgroos_>
Cool. I'd like to check it out, thanks.
15:19
What do you use it for exactly?
15:19
<robehend1>
dgroos_: basically, when your working in a profile, Sabayon creates temp files under /tmp. What Gadi and I found out was that if you go in and delete that temp file before saving hte profile, it seems to work better
15:19sugoruyo has quit IRC
15:20
<robehend1>
dgroos_: I use sabayon to set the default look of the Gnome for the kids, add desktop launchers, set up panels, etc. I've looked at the edubuntu-menueditor and had some success with it, but it wouldnt do what I completely needed.
15:20
<dgroos_>
? interesting... Is that little hack published on the sabayon page? It would be a good thing...
15:21
<robehend1>
dgroos_: I believe theres a bug report up, but its not 100% reliable
15:22bobby_C has joined #ltsp
15:22
<dgroos_>
Nice, sounds like your setup is more advanced than mine at this point.
15:23
I too tried edubuntu-menueditor and it looks cool but it doesn't quite work for my setup (can't remember why at the moment) but there is a work around that Marc sent me.
15:23
<robehend1>
the clobbered solution m4xx and myself came up with was to create a user, we'll call him setup, and configure things the way you want. Then, copy all the files of his home to /etc/skel, so when users are created, they inherit it all
15:24
then m4xx created a perl scrip to automatically bring that in, worked nicely.
15:24
heck, even worked with my users that auth to MS AD
15:25
<dgroos_>
robehend1, that's cool. Maybe this summer I'll have some time to try and learn about and incorporate these ideas.
15:27
<robehend1>
dgroos_: so, if i can be so bold, how are you using LTSP in the classroom? I'm not a teacher, just the CIO, so having a teacher perspective is a great asset
15:27
<dgroos_>
I don't suppose you have a list of steps you do when you set up a server for an educational setting? I made this wiki page to try and get it going...https://help.ubuntu.com/community/EdubuntuDocumentation/EdubuntuCookbook/BasicSetup
15:28
<robehend1>
dgroos_: saw that, and will be more than happy to add to it. Just added another server to our elementary yesterday, actually. so it's fresh in my head

lol sorry guys
15:30
i had a focus problem.
15:30
<robehend1>
my most common is LS
15:30
<dgroos_>
You saw my setup so you can see that I use them pretty much in every thing I have the students do.
15:30
do you mean what apps do I use? or?
15:31
<robehend1>
dgroos_: you wouldnt happen to have a sampling of lesson plans and such I could share with my staff? I notice I have to spoon feed them more than anything to convince them its worthwhile
15:31
that is, if it doesnt come from Pearson
15:31
or Mcgraw-Hill
15:31
<dgroos_>
Also, here's the English page for sch-scripts: http://users.sch.gr/alkisg/tosteki/index.php?topic=3220.0

ah, nice, thanks

Here's a link explaining some of my setup and my vision of what I'm trying to do with computers... http://plonedev.mpls.k12.mn.us/gcos

hmmm... that's tough if the teachers are not adventuring out to use the great technology. I'd say show them a couple killer applets such as:

Here's one of my favorites--perhaps you've seen it? http://learn.genetics.utah.edu/content/begin/cells/scale/
15:47
<robehend1>
lets check it out. also, did you get ppc macs working as thin clients?!
15:47Barcelo has left #ltsp
15:48
<dgroos_>
but there are plenty of other things--have you seen the phet site: http://phet.colorado.edu/
15:49
<robehend1>
i have not, but downloading as we speak
15:49bobby_C has joined #ltsp
15:50
<dgroos_>
When I first looked at Ubuntu I tried to get it to work on some old macs I had but it was dreadfully slow so since then I get old PIII's and P4, remove the HD and use them.
15:51
What do you use?
15:51
<robehend1>
ah, same here. to bad, i've got a stack of old macs
15:51
mostly some old celerons and p4s, though always looking for more old machines.
15:52
<dgroos_>
Hmm... Have you seen GetSTEM? It's part of the MN High Tech association (they do the TEKNE awards). http://www.getstemmn.com/Pages/Default.aspx
15:53
<robehend1>
we have used that, yes
15:53
<dgroos_>
They would be a great resource for old PC's, I'd think. I've thought about tapping them but haven't needed to since there are quite a few here in Minneapolis Public Schools.
15:53
<robehend1>
ya, we're a pretty small school, sub 700 enrollment
15:54
<dgroos_>
Cool--how has it worked out? I posted there once and got a guy who knew linux help me to solve a printer issue :)
15:54
<robehend1>
its been working nicely, actually. Replaced the entire media center with thin clients, and have now deployed them in grades k-4
15:55
we're calling it our "party with the penguin" deployment, and the younger kids eat it up
15:55
<dgroos_>
That's really great. I'm trying to persuade MPS to move more towards open source and Linux and thin/fat clients.
15:55
:)
15:55
<robehend1>
Good luck. Pearson wont budge an inch on Testnav requiring windows or mac
15:56
and MDE wont go to testnav 7, which is web based, until 2013 they're saying
15:56
<dgroos_>
Good for you for pushing them! How about running it in a VM windows--possible?
15:57
I wonder if WINE would work :D
15:57
<robehend1>
ha, we think alike
15:57
I've got it on my desktop, and it runs via wine fine. I'm waiting for the state to approve me on the training side of pearsonaccess, so I can test it on a live test
15:57
<dgroos_>
This is really cool to find another Minnesotan using LTSP!
15:58
<robehend1>
have you ever worked with Reason Computers? they are out of minnetonka
15:58
<dgroos_>
:) Was it hard to install it?
15:58
Not familiar with them.
16:01
<robehend1>
not to bad, actually
16:04
<dgroos_>
That would be something to publish.
16:04
<robehend1>
hmm? not following
16:05
<dgroos_>
robehend1: you don't have smartboard software running on any thin clients?
16:05vagrantc has quit IRC
16:05
<robehend1>
nope. no current need, though i've gotten the Smart software running on ubuntu 10.04 before
16:06
would probably set it up through a fat-client though
16:06
<dgroos_>
Simon R gave an idea how to do it but I can't seem to get past the dependencies -- QT Pascal interface not found...
16:06
I should set up at least 1 test fat client. How hard is it?
16:06
<robehend1>
not hard at all.
16:07
myself, I just built a new chroot on the server, and sent a few mac addresses that img
16:08
<dgroos_>
So you define the clients you want to boot via which image base on mac addresses in the lts.conf?
16:08
*based
16:08
<robehend1>
that'd work, yes. I run it off my main DHCP, myself, but lts.conf should be fine
16:08RiXtEr has quit IRC
16:08RiXtEr has joined #ltsp
16:08
<dgroos_>
I think I'll try that.
16:09
<robehend1>
you'll want to make sure its a pretty decent client though. 512 megs ram at least, i'd say
16:09
<dgroos_>
I'm doing 512 on all my localapp clients and they seem to be OK but I was going to put a gig on the fat client.
16:10
<robehend1>
i'm running them on 512, runs fine
16:10
firefox, flash, all of it
16:10
<dgroos_>
Really!!!?
16:10
<robehend1>
mhmm
16:10
my 1-4th graders use them every day for Accelerated Reader tests
16:10
and by god I'd hear about it if they couldnt do *that*
16:11
<dgroos_>
I should do that then since there is an app that I think will only work on a fat client, and I think another will do well.
16:11
:)
16:11
<robehend1>
which one is that? i may have tried it ;)
16:11
<dgroos_>
I'm not a huge fan of accellerated reader/math but it has it's place.
16:11
CmapTools.
16:11
<robehend1>
yep. for teachers who dont want to make their own curriclum
16:11
<dgroos_>
Right.
16:12
<robehend1>
never tried cmap tools
16:12
<dgroos_>
CmapTools is an awesome program. For example, I made the instructions for an activity today using it
16:13
<robehend1>
whats it do?
16:13
<dgroos_>
and since it not only can be accessed on the local client but also on a server, the maps it makes are browsable via firefox etc.
16:14
I'll give you a few examples...
16:15
Here's for the lesson today... http://cmap.mpls.k12.mn.us/rid=1J21RYPD6-7M82X1-683/FM--Experiment%20with%20semi-permeable%20membrane.cmap
16:15
<robehend1>
oh, mapping
16:15
I use Google Apps draw for that
16:16
not sure how i feel about being part of the Google botnet, but i do love me some google apps
16:16
<dgroos_>
This one has been developing for 20 years and is pretty slick, it too can do the simultaneous editing over the web (with the cmaptools client working on files on the cmapserver).
16:16
<robehend1>
ooo thats nice
16:16
hmm, so is this sch-scripts thing.
16:16
<dgroos_>
I love google apps as well!
16:17
<robehend1>
its been a big boon to people who hate open office.
16:17
<dgroos_>
sch-scripts is great. alkisg has promised to make a 'proper' application out of it when he's done with his degree in 2 years.
16:18
Sch-scripts works well now, but it can be improved.
16:18
<robehend1>
ya, i'm going to have to play with it
16:19
are you like logging right into the server and running it locally, for yourself? our servers headless and sits back in the room, so i'm doing it over x forwarding
16:20
<dgroos_>
I'm sitting at a client and do everything on that (though right now on a laptop).
16:20
<robehend1>
hmm. wonder if i could install it on a non-client and use it
16:21
<dgroos_>
I think so--alkisg had to do a work around for me to do it on the client--I think they do it on the server though...
16:21
<robehend1>
that makes sense
16:21
and the part i'm really concerned about, locking, seems to be working fine
16:21
<dgroos_>
Here's a concept map a student is making as he works to figure out cells, using the words that are required by the district: http://cmap.mpls.k12.mn.us/rid=1J15G0PC9-5FP1MV-B5/Christian--Cell%20concept%20map.cmap
16:22
<robehend1>
ooo nice
16:22
ya, bit more than google apps draw
16:22
<dgroos_>
It's a work in progress--I think I'll use it as a final unit assessment.
16:22
(their concept maps)
16:22
<robehend1>
that works
16:23
can't wait to see my students faces tommorrow when I lock their screens, and they see Greek letters..
16:23
<dgroos_>
:D
16:23
Tell them Percy Jackson got virutalize :)
16:23
<robehend1>
ha
16:24
i'm going to have to configure Wake on Lan though, to make sure the clients work
16:24evil_root is now known as zz_evil_root
16:24
<dgroos_>
Let me know how it goes. If we can get several people using it maybe it can be updated earlier--with more help.
16:24
<robehend1>
indeed. I'd be happy to get something like that up and running
16:25
<dgroos_>
If you can get WOL to work let me know! I've had no luck.
16:25
<robehend1>
did you get the view user screen working?
16:26
<dgroos_>
I'd be happy to test it--I don't know programming --'cept for BASIC in college 30 years ago :)
16:26
Yes.
16:26
<robehend1>
i'm learning python as I go, slowly but surely
16:26
what about teacher screen sharing
16:27
<dgroos_>
Really, most everything works that I've tried except WOL.
16:27
<robehend1>
hmm
16:27
i'm gonna assume it has to do with running via x-forward then
16:27
<dgroos_>
Seems I tried it once and it did work.
16:27
<robehend1>
the program runs, and I can lock machines and such, but beyond that, nada
16:28
<dgroos_>
I'm guessing alkisg would be happy to help get it going.
16:28
which version of sch-script-client are you using?
16:28
<robehend1>
the one that was in the link you sent me, 10.04.38
16:29
<dgroos_>
OK good.
16:29
<robehend1>
for funsies, i'm going to install the client and the script on my laptop, see if it hooks up
16:29
<dgroos_>
you run LTSP on your laptop?
16:29
I probably could...
16:29
<robehend1>
nope, standalone 10.04
16:29
i'm going to see if the standalone will hook up to an existing ltsp
16:30
<dgroos_>
sure
16:31
<robehend1>
so, how did you lockdown the desktop for your users, if you did? I'm talking things like the gnome menu, keepign em out of the command prompt, etc
16:31
<dgroos_>
command prompts not a problem--don't have that sophistication here.
16:32
<robehend1>
hmm ok
16:32kesou has quit IRC
16:33
<robehend1>
no dice on running it on a standalone, btw. doesnt see ltsp, and no way to hook it too it
16:33
<dgroos_>
This year I haven't had as much problem as before and haven't had a huge problem. The biggest issue are apparently this site is more fun than my stuff: http://coolmath.com/ :)
16:33
<robehend1>
our kids like TuxMath
16:34
<dgroos_>
I've got 9th and 12 graders.
16:34
<robehend1>
we use it with 7-12. Oddly enough, the 11-12 like it more than the 7th
16:34
mostly becuase we give them the harder ones, where you get thing such as 11*12-22+14 , and you have to solve in your head in under 10 seconds
16:35
<dgroos_>
cool! Does it have advanced stuff on it or is it mainly just shootin' astroids and fish?
16:35
right, nice.
16:35
<robehend1>
it works great for the kids that are below grade level, as well
16:35
which is becoming more and more and more, sadly
16:36
<dgroos_>
Well, I've got a job tomorrow, that's for sure.
16:36
<robehend1>
fatclients take forever to build, btw
16:37
even with using hte servers package cache
16:37
<dgroos_>
robehend1: It's been great talking. It's time to head home to the family but as they say, 'I'll be back..." :D
16:37
OK good to know.
16:37
<robehend1>
yep, see you around!
