<muppis>
alkisg, ah. There you are at last. If you remember, which I doubt ;), I had a problem with muted sound in client which was annoying as being htpc client, but I located it to be hw problem as locally installed Ubuntu got same symptoms.
05:31
<alkisg>
Hi muppis. And?
05:32
<muppis>
alkisg, so I think I had to get better mobo. :)
05:32
<alkisg>
Ah, I thought you fixed it :D
05:33
<muppis>
Not yet. Just noticed it last weekend when had little time for it. :)
05:33
<alkisg>
lspci -nn -k, see the pci id, and google for it with "ubuntu" in the search string :)
05:34
<muppis>
I'll try that. Just got more important things to get fixed right now. Have to change an engine to my car. :)
05:35
<alkisg>
Hehe. OK, good luck with that, /me goes back to writing delphi programs for his phd.. :-/

<Hyperbyte>
Hm... while booting the thin client with 'splash' disabled, I see one red "fail" in the list of things starting up
08:27
It disappears quite fast, as it's near the end of the startup... but I believe it's something like the 'regular background processing daemon'
08:27
Is this normal behaviour?
08:29Parker955 is now known as Parker955_Away
08:30
<Hyperbyte>
Hrm, it's actually called the 'regular background program processing daemon', and I believe that's Ubuntu's nickname for cron... or at least that's what I gather from Google
08:31
Why would my thin client be trying to start cron?
08:39
<alkisg>
Hyperbyte: cron is enabled by default, some people even put automatic shutdown scripts on cron lins
08:39
lines
08:39
It's even configurable from lts.conf, see the man page
08:39* alkisg disables cron by default because he doesn't like update-apt-xapian-index etc running on thin/fat clients
08:40
<alkisg>
CRONTAB_01..CRONTAB_10
08:40
string, default unset
08:40
A crontab line to add for a thin client.
08:41
<Hyperbyte>
I think I misread, the 'fail' line isn't about cron but another daemon. :\
08:42
Why the 'fail' has to be on the complete right and the program on the complete left is beyond me, makes it impossible to see which fail/ok belongs with what program... but alas.
08:42
Thanks for the cron tip.
08:42
<alkisg>
Hyperbyte: using dmesg or `cat /dev/vcs7` might help you see the message
08:42
<Hyperbyte>
I'm having a much bigger problem at the moment, after running ltsp-update-image --arch i386...
08:43
I'm getting kernel panics on the thin client. "not syncing: VFS: Unable to mount root fs on unknown wn-block(8,1)"
08:43
NBD problem, right?
08:43
<alkisg>
11.04? no nbd-proxy there, right?
08:43
<Hyperbyte>
Don't think so, no
08:44
<alkisg>
Does this work? sudo mount -o loop /opt/ltsp/images/i386.img /mnt
08:44
(server)
08:44
<Hyperbyte>
yessir
08:44
<alkisg>
Hm... ok, unmount it
08:44
<Hyperbyte>
Already done. :)
08:45
Could I 'service nbd restart' with clients logged in?
08:45
<alkisg>
There's an option in nbd-server about this
08:45
In dpkg-reconfigure nbd-server
08:45
It asks whether it should disconnect clients on nbd restarts etc
08:46
So it depends on what you put there. And I don't know how inetd relates to that.
08:46
So ... nah, don't try it :)
08:46
<Hyperbyte>
I actually don't think I run nbd via inetd
08:46
<alkisg>
LTSP does, unless you modified it
08:47
Hyperbyte: whenever you get a kernel update on the chroot, and you run ltsp-update-image, you also need to run ltsp-update-kernels - did you?
08:47
I.e. the initrd in the tftp dir should have the same kernel as the nbd disk
08:48
<Hyperbyte>
I ran the dpkg-reconfigure nbd-server command, but cancelled after you suggested it didn't work
08:48
It said stopping nbd server. =)
08:48
But I run nbd as a server, not via inetd
08:48
Didn't know LTSP did that. Does it make much difference?
08:49
<alkisg>
Not much. So, grep nbd /etc/inetd.conf returns nothing for you?

<Hyperbyte>
Month or so ago I installed xinetd, to test something on Ubuntu
08:50
It automatically removed inetd for me, and then nbd didn't work anymore... I figured LTSP might use inetd
08:50
<vagrantc>
aha
08:50
<Hyperbyte>
But a service nbd start fixed it.. so I didn't give it much more thought until now.
08:50
Should I reverse some things? :)
08:50
<vagrantc>
we need to switch to named NBD devices, and then can probably switch to the regular NBD again
08:50
<alkisg>
Better revert to the defaults, it's always easier for troubleshooting :)
08:51
vagrantc ++ :)
08:51
Both of them on the same ltsp release would be better
08:51
And we can also completely stop depending on inetd :D
08:52
(I think stgraber had some small modifications for ldminfod to act as standalone)
08:52dlezcano has left IRC (dlezcano!~dlezcano@AToulouse-159-1-98-21.w92-134.abo.wanadoo.fr, Ping timeout: 258 seconds)
08:52
<Hyperbyte>
Is it okay for troubleshooting if I leave it without inetd for now? ;)
08:53
<alkisg>
Hyperbyte: hehe sure I don't have problems when people say they have customized setups *before* the troubleshooting process :P
08:53
<vagrantc>
ldminfod as standalone... curious
08:53
<Hyperbyte>
Well, I realize. =)
08:53
<vagrantc>
running from inetd is pretty flexible, though ... and get a lot of services for free such as logging ... not sure moving it out of inetd is a good idea
08:54
<Hyperbyte>
My biggest failure in all this was... I need some xinetd like functionality... and Fedora uses xinetd by default, not inetd... didn't even know there was anything else. So I just did an apt-get install xinetd. Beginner's mistake. =)
08:54
<vagrantc>
Hyperbyte: so you're using nbd-server's init scripts, or running nbdrootd from xinetd?
08:54
<alkisg>
vagrantc: Logging for what? nbd-server? Doesn't nbd-server log already? Or you're only talking about ldminfod?
08:54
<Hyperbyte>
vagrantc, nbdserver init
08:54
<vagrantc>
alkisg: ldminfod logs whenever you get a connect message... which i often find useful with troubleshooting
08:55
<alkisg>
vagrantc: well, adding 1 line for logging would be rather easy, and would save us from depending on inetd
08:55
<vagrantc>
it's such a small dependency ... but whatever.
08:56
the other thing is that i don't know if nbd-server provides a mechanism to automatically configure what to connect with
08:56
<Hyperbyte>
Meanwhile... how do I get inetd back? :)
08:56
<alkisg>
vagrantc: nope, I think it only provides a configuration file (not even dir)
08:56
Hyperbyte: apt-get install openbsd-inet ?
08:56
d
08:56
?
08:56
<Hyperbyte>
openbsd-inetd, ah...
08:57
<vagrantc>
alkisg: i'll poke Yoe to fix that.
08:57
<alkisg>
Cool
08:57
But even as it is, it's no different to modifying inetd.conf
08:58
And also there's no need for port auto-assignment with named exports
08:58
We can just say "/opt/ltsp/images/i386.img" in the name section
08:58
And using that in the root-path of dhcp would also be a good idea imho
08:59
<vagrantc>
alkisg: no, with inetd, there's update-inetd, which is a policy-compliant mechanism to update /etc/inetd.conf
08:59
<alkisg>
Ah, right
09:00
<Hyperbyte>
alkisg, okay... got inetd running, no more kernel panics, now it says can't connect to nbd. Which I can confirm, telnet localhost 2000 = connection refused.
09:00
<alkisg>
Hyperbyte: stop the nbd-server, remove the nbd-server configuration file, and start openbsd-inetd
09:00
Then try again
09:00
<Hyperbyte>
What I find most curious is that all nbd server processes on the LTSP server are gone, but clients are still happily logged in. :)
09:01
alkisg, I did.
09:01
inetd is started.
09:01
<alkisg>
Hehe, until they try to access something from the file system
09:01
<Hyperbyte>
nbd-server is off
09:01
root 24826 0.0 0.0 8392 544 ? Ss 10:57 0:00 /usr/sbin/inetd
09:01
<alkisg>
And grep nbd /var/log/daemon.log while you try telnet shows what?
09:02
(and you do have 2000 in /etc/inetd.conf, right?)
09:02
<Hyperbyte>
Yes, inetd.conf is default.
09:02
I have no daemon.log
09:02
<alkisg>
Erm, you mean no nbd messages there? Or no daemon.log at all?
09:03
Try syslog they should be there too
09:04
<Hyperbyte>
Nothing appears in syslog when I do telnet localhost 2000
09:04
Hrm
09:04
inetd isn't listening on 2000, only 2001
09:04
<alkisg>
grep nbd /etc/inetd.conf
09:04
Results?
09:05
<Hyperbyte>
9572 stream tcp nowait nobody /usr/sbin/tcpd /usr/sbin/nbdswapd
09:05
2000 stream tcp nowait nobody /usr/sbin/tcpd /usr/sbin/nbdrootd /opt/ltsp/images/i386.img

2001 stream tcp nowait nobody /usr/sbin/tcpd /usr/sbin/nbdrootd /opt/ltsp/images/amd64.img
09:05
<alkisg>
And also: ls /opt/ltsp/images/
09:05
Are they both there?
09:05
<Hyperbyte>
i386.img
09:05
<alkisg>
OK, run: sudo ltsp-update-image --force
09:05
This will automatically fix inetd
09:06
And update kernels too
09:06
<Hyperbyte>
First line
09:06
Cannot determine assigned port. Assigning to port 2000.
09:06
Good I suppose? :)
09:06
<alkisg>
Yup
09:07
<Hyperbyte>
Can telnet localhost 2000 too now
09:09
And log in. :)
09:09
Nice one!

<Hyperbyte>
alkisg, so how would I go about disabling cron on a thin client?
09:16
<alkisg>
Delete $CHROOT/etc/init/anacron.conf and cron.conf
09:16
Or dpkg-divert them to not have to delete them after upgrades too
09:16* alkisg would prefer services to be disabled by an initramfs scripts instead of directly modifying the chroot
09:17
<alkisg>
(speaking generally for ltsp-build-client, not for this cron case)
09:17
<Hyperbyte>
It's the restoring sound card mixer status that says 'fail' by the way.
09:17
<alkisg>
https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/609766
09:18
Or maybe no, not that one
09:18
Maybe it's just that the chroot was never booted, so no mixer status was ever saved
09:18
That's one of the cases where booting the chroot with vbox would help :P
09:19
<Hyperbyte>
=)
09:20
Any way I can make it stop doing that on startup?
09:20
<alkisg>
Delete that service too?
09:20
<Hyperbyte>
No idea what service it is. :D
09:21
Ah
09:21
it's in /etc/init/
09:22
What's the difference between /etc/init/ and /etc/init.d/ ?
09:22
<alkisg>
upstart vs system v init scripts
09:23
<Hyperbyte>
Ah.
09:25
All fail's gone. :)
09:25
<alkisg>
Nice :)
09:41
<Hyperbyte>
Can an LDM theme logo have alpha-transparency in it
09:41
+
09:41
?
09:41
(sorry, my brain isn't working properly this morning)
09:42
<vagrantc>
Hyperbyte: there's an easy way to find out...
09:42
:)
09:43
<Hyperbyte>
Well not really, because I'm gonna have to bug my boss to get off his PC so I can use photoshop. :)
09:43
<alkisg>
Hyperbyte: just put a transparent logo on the chroot live, and restart ldm
09:44
<Hyperbyte>
Although I suppose I could search some other alpha transparant png and use that to test... figured someone here might know though. :)
09:44
<alkisg>
No need even to ltsp-update-image...
09:49
<Hyperbyte>
Okay, it supports alpha transparency in PNG's. :) That's nice.

<quietone>
where do I learn how to set up a thin client? I thought it had to do with the bios, but on an old desktop I saw nothing. I am lost.
10:48
<Gremble>
you need to enable PXE boot quietone
10:49
<quietone>
Gremble, I gather that. But how? Is that a bios setting? If so, I couldn't find it.
10:49
<Gremble>
it's usually enabled in the BIOS yes
10:49
not all machines have it
10:49
<quietone>
Gremble, is it always called PXE in the BIOS settings?
10:50
<Gremble>
actually it needn't be in the BIOS, but can also be on the ROM on a network card
10:50
it may be called "network boot" or some such thing
10:50
but usually there is at least a reference to PXE
10:50
what machine are you working on?
10:50vagrantc has left IRC (vagrantc!~vagrant@conference/debconf/x-ifcodvasmlmzzmcs, Ping timeout: 240 seconds)
10:51
<Gremble>
quietone, you can also use etherboot, which can be run from USB,CD,HD whatever
10:51
<quietone>
Gremble, I think the machine was the Dell desktop, don't know it's age.
10:52
<Gremble>
'was' a Dell desktop? you don't have it present?
10:52
<quietone>
Gremble, sorry (it is close to my bedtime). The machines are at work and I am at home (and rather tired)
10:53
<Gremble>
Dell desktops usually have a network boot / PXE option, but not always
10:53
good luck with finding it, or sorting out etherboot somehow
10:54
<quietone>
Gremble, my laptop is dell and there is something like 'wake on lan' - would that be it for this machine?
10:55
<Gremble>
no "Wake on LAN" or WOL is a feature that allows a special packet to be sent and literally wake the machine up from being powered off
10:57
look in the boot options
10:57
or press the boot menu key if there is one offered
10:58
<quietone>
Gremble, OK. I'll examine my BIOS in the morning.
10:59
Gremble, and I will give etherboot a try tomorrow.
10:59
Gremble, Thank you very much for clearing it up for me.
11:01
<alkisg>
quietone: is the card onboard?
11:02
Usually, onboard cards have pxe rom, and not-onboard-cards only have pxe rom *if* they're expensive
11:02
Cheap pci cards don't have pxe rom
11:03
<quietone>
alkisg, I don't have a clue. it is just a dell box to me.
11:03
<alkisg>
Onboard = the rj45 jack, the network socket, would be close to the sound holes
11:04
PCI = it would be on a separate slot, you could see it from the outside of the box
11:04
Onboard = http://www.overclockersonline.net/images/articles/soyo/dragonultra/ports.jpg
11:07
<quietone>
alkisg, I guess on board then
11:07
<alkisg>
OK, see your bios settings then. There can be up to 3 of them:
11:07
(1) enable boot rom (2) enable boot from lan (3) boot sequence
11:08
(other boards might have just 1 or 2 of them)
11:10
<quietone>
alkisg, i don't recall finding 1 or 2 and the boot sequence had the hard drive, CD, and a character string that meant nothing to me
11:10
<alkisg>
LAN?
11:11
Anyway, it'll be easier if you are in front of the bios while chatting about it, so maybe leave it for tomorrow.
11:11
<quietone>
alkisg, I can check in about 10 hours, when I go back to the office ;-)
11:12
alkisg, but I take your point, to read carefully
11:12
<alkisg>
Yup
11:13
<quietone>
alkisg, thanks, talking always clears things up for me. good night.

<Hyperbyte>
Gimp isn't gonna work for us... we use the entire Creative Suite... meaning Illustrator, Indesign and Photoshop.... we do all our graphic work, brochure making, etc, ourselves
11:38
It would take years to port everything that's already made (and which we re-use every year) to Photoshop
11:38
*** to Gimp
11:38
Plus Gimp and Scribus and OpenOffice just can't match up to the ease of use of CS3...
11:38
Sorry. :)

<andygraybeal>
i heart inkscape!
11:42
couple of weeks ago, i was trying to figure out how to get visio stuff into inky, i'm still working on it.
11:43
er i mean i never figured it out, and now i'm onto other things, but look forward to going back to that.

:)
12:06
<alkisg>
I managed to switch all my graphics from photoshop to gimp
12:07
But I haven't yet had the time to invest in inkscape
12:07
Also I found openoffice had much more layout power than ms word, even with the occational bugs
12:20
<Hyperbyte>
Compared to Indesign they all kinda suck though. Although it depends on how much of the Indesign features you use. But if you use Creative Suite like we do, there's really not a good open source or even Linux alternative.
12:22
OpenOffice really rocks though, compared to Microsoft Office. :)
12:29
<alkisg>
Hyperbyte: is indesign suitable for writing a whole book? Or only for formatting it after you write it?
12:30
Also, does it support automatically mirrored images based on odd/even pages? Or, different background images per paragraph? (like css)
12:31
What I like about openoffice is that once I'm done with my style sheet, I never use the formatting toolbar anymore.
12:31vagrantc has joined IRC (vagrantc!~vagrant@conference/debconf/x-hliugwwtrqustmml)
12:32
<Hyperbyte>
alkisg, I think Indesign supports all that, but it's not really for writing books. It's better for brochures and flyers, which require lots of special formatting.
12:32
<alkisg>
Ah, ok, so for books the best so far for me is still openoffice, paid or not
12:33
I don't like to separate the writing/publishing phase for the manuals etc I write, and it's much better than anything else i've tried
12:33
<Hyperbyte>
For books I would use OpenOffice writer. That's what we use for all our instruction manuals, etc.
12:34
If you want an example, this is our brochure of last year, which we made in Indesign: http://www.set-reizen.nl/SET-Reizen%20Brochure%20(winter-zomer-2010-2011).pdf

Well while I could do the same with any program the point of course is that it would be much, much harder to do it, and unfortunately that doesn't show up in the pdf (how easy or not it was).
12:38

Hi
15:31
i was just asking myself if it is possible to use ltsp squashf image and kernels, write them to thin client flash memory, and boot on it ?
15:32
<vagrantc>
conceptually, yes... in practice they make some assumptions about how thee system is running
15:32
so you might have to ttweak a few things
15:32
<layus>
is the kernel tweaked ? or initrd ?
15:33
anyway thanks :-) I'll try this tomorow
15:34
<alkisg>
It's tweaked
15:34
It won't boot without modifications
15:34
But why would you try that?
15:34* alkisg wants to do that for fat clients, with e.g. 5 Gb nbd images, which only require a little network traffic, but doesn't think it helps with thin clients
15:34
<vagrantc>
i've long wondered about doinng something similar to TCOS with LTSP ... it should basically work
15:35
<alkisg>
I've seen .iso CDs that can boot ltsp clients
15:35
And local hd images, from some university
15:35
<vagrantc>
there was also a project in brazil that did that
15:35
loading a thin-client image into ram ...
15:36
that way the boot server could be really low resource once they were booted
15:36
<layus>
in fact that would prevent complete service shutdown in cases where our ltsp-server is down.
15:36
<vagrantc>
dealing with thousands of thin-clients froma single server
15:36
<layus>
sounds interresting too :)
15:37
<alkisg>
Yeah copying the whole image to RAM sounds better suited to layus' use case
15:37
<vagrantc>
obviously, it needed powerful application servers
15:37
right
15:37
<alkisg>
But of course the client session would collapse; and in the best case the client would fallback to ldm
15:38
<vagrantc>
seems to make more sense with fatclients ... although LTSP style fatclients still use the server for homedirs, typically
15:38
<alkisg>
Some wireless nfs link is enough for nfs home dir on the server
15:38
So for students bringing in laptops to their schools, it would suit them fine
15:38
<vagrantc>
could also fall back to a kiosk if the server gets disconnected
15:38
<alkisg>
Or for computer labs with awful local networks
15:39
<vagrantc>
all sorts of interesting possibilities :)
15:40
<layus>
in fact, we have got many working servers, for scientists...
15:40
an they connect to them with teir thin client
15:40
but the nbd server is just a virtual one
15:40
<vagrantc>
dare i say it, an RDP-oriented network
15:41
<layus>
... :)
15:41
<vagrantc>
that would be a use-ccase that makes sense
15:41
<dingz>
how do you want to make sure, students only mount their own homedir via wireless NFS?
15:41
<layus>
but our ndb server is just a virtual one (vmware)
15:41
<alkisg>
But why would one use ltsp in this case, instead of e.g. a very light/small tinycorelinux?
15:42
Which wouldn't need any modifications, and wouldn't take much ram for its image?
15:42
<layus>
no reason, but ltsp is easy to use and has many scripts to connect to both rdp and xdmcp
15:43
and because i have only 150M of flash memory...
15:43
<alkisg>
That's a reason *not* to use ltsp
15:43
<layus>
y
15:43
<vagrantc>
ltsp will push the limits of that 150M, if that's enough at all
15:43
<alkisg>
The ltsp image is >200 mb, while tinycorelinux is < 50 mb
15:43
(i mean, the stock ubuntu one, compressed)
15:44
Maybe you can get it to fit at 150, but that's stretching it
15:45
<vagrantc>
plus the uncompressed kernel+initrd
15:45
well, the vmlinuz+initrd
15:45
<layus>
i use the debian one, and, yes, it's hard to stretch
15:46
if we use ltsp, it's for it's central configuration scheme.
15:46
one file to configure everything.
15:46
the os would only be a rescue solution.
15:47
but it seems hard... maybe we buy some more flash memory
15:47* alkisg had local knoppix installations for situations when the ltsp server was down But ever since meeting debian/lxde, I've decided I want that for local installations instead :)
15:48
<alkisg>
It even works with < 64MB RAM!
15:48
I'm starting with passing "single" on the command line, and then only invoke whatever services I really need
15:49
<layus>
yes, but we have to reconfigure it to enable connection to some servers and no local access
15:49
<alkisg>
Well the users won't have root, so it shouldn't matter if they had local access to the read-only 150 mb
15:50
<layus>
because even in case of failure, we want no user modifying things locally, nor trying to connect to random servers names
15:50
<alkisg>
Ah so LDM is handy there, instead of writing your own set of scripts for that
15:51
<layus>
yes
15:52
I still can't figure how to fit a debian/lxde in 64 MB
15:53
<alkisg>
I'm using recycled desktops, so they have 1 to 6 Gb local disks
15:53
That's why I suggested tinycorelinux, it would fit there easily
15:53
Ah sorry
15:54
<vagrantc>
64MB of ram, not disk
15:54
?
15:54
<alkisg>
Correct: for local disks, I don't have a size problem, because of the above ^
15:54andygraybeal has left IRC (andygraybeal!~andy.gray@obsidian.casanueva.com, Ping timeout: 258 seconds)
15:54
<alkisg>
and for RAM, passing single in the command line gets you with only 8 mb ram used
15:54
su'ing to some user and starting X, gets you to a little below 30 RAM
15:55
And you have about 30 more for some basic programs
15:55
<layus>
that's ok
15:55
for sure
15:56
so i have to look to tinycorelinux
15:56
is it easy to use ?
15:57
<alkisg>
Dillo with 30 MB RAM: http://imagebin.org/index.php?mode=image&id=164967
15:57
tinycorelinux has some learning curve
15:58
<layus>
:)
15:58
<alkisg>
Ah you may also want to look at slitaz
15:58
Both are actively maintained and aim at low disk space
15:58
<layus>
thx
15:59
just remembered another cool stuf with ltsp.
15:59
it allows network booting
15:59
<alkisg>
Tinycorelinuz does that too
16:00
It's just a kernel + initrd, loaded into ram
16:00
So it doesn't matter where it boots from
16:00
<layus>
jes, but how to write it in the thin client ?
16:00
<alkisg>
And to add programs, you concantenate packages to the initrd
16:00
<layus>
ah... full initrd install then.
16:01
<alkisg>
Boot some os from the network, either ltsp or tinycorelinux, and copy it to the local disk
16:01
<layus>
seems i lack many knowledge
16:01
<alkisg>
It's just 2 files
16:01artista_frustrad has left IRC (artista_frustrad!~fernando@200.247.43.2, Ping timeout: 255 seconds)
16:01
<alkisg>
Of course you'll need a local boot manager
16:01
<layus>
oki
16:01
like grub ?
16:01
<alkisg>
Yup
16:01
I think it has a local installation icon too
16:02
Which does that semi-automatically
16:02
<layus>
k, i will try this, wich seems pretty interresting. ( but tomorrow :)
16:02
thanks a lot
16:03
<alkisg>
You're welcome
16:03
<layus>
oh, and i made a little script that allows to use idesk within ltsp
16:03
i ll post it on the forum
16:04
it's just a small modification of the screen.d/menu script
16:04
but it issues "openvt" before any connection call
16:04
so any connection opens in anoter vt, allowing user to open many connections from the same menu
16:05
and the menu is always rechable with ctrl+alt+F1

18:49
now what do I need to sync clients to it
18:50
so ltsp-localapps is time accurate
18:50
<Hyperbyte>
ntpdate <server ip> works?
18:50
<TheMatrix3000>
yes
18:50
<Hyperbyte>
Okay
18:50
Then just getltscfg -a please
18:50
On pastebin
18:50
On the thin client
18:59
<TheMatrix3000>
http://pastebin.com/LKCA82jY
18:59
<Hyperbyte>
And it doesn't timesync currently, on startup?
19:00
<TheMatrix3000>
ltsp-localapps firefox does not show correct time
19:00
<Hyperbyte>
Try ltsp-localapps xterm and then typing 'date'
19:00
Probably give the same result, but a much better way of checking.
19:01
Disable the Ubuntu splash screen for the thin clients, see what it says about ntpdate during boot
19:01
!quiet-splash | echo TheMatrix3000
19:01
<ltsp>
TheMatrix3000 quiet-splash: to disable the splash screen in Ubuntu, in order to see any boot error messages, run `sudo gedit /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default` and remove quiet splash ..
19:05
<TheMatrix3000>
ah, nvm
19:05
i guess it works now
19:08
<Hyperbyte>
:)
19:09

19:11* alkisg suggested that too, but apparently the fix was included in ubuntu 11.04
19:12

<warren>
stgraber, your latest ldm commits broke python2
23:44
stgraber, python-2.6.6
23:45
stgraber, python3 is a different language, if you want to rely on it, put in entirely different scripts.
23:46
stgraber, respectfully, I'm backing out your change.
23:46
stgraber, since it breaks build on pretty much every distro.
