<rm-rf>
i have a site that is running ltsp for their service writers and mechanics
09:09
the owner has asked me if it is possible to transfer sessions
09:10
example: he's logged into machineA, and when he logs into machineB he wants his desktop and all the apps that were opened on machineA to show up, as well as have machineA log out so someone else can use it
09:10
should i tell him to take a flying leap, or is this remotely possible?
09:18alexqwesa_ has quit IRC
09:20
<alkisg>
rm-rf: with ltsp, no. With freenx or vnc, sure.
09:20
And of course you could use both of them.
09:20
(i.e. ltsp + freenx)

i'm pondering tagging a new ldm version today...
13:02Ahmuck has quit IRC
13:06
<stgraber>
vagrantc: please do, I'll need it too
13:07
I'll also tag ltsp-trunk again to have that last fix I pushed, so if someone has something to push, please do it now ;)
13:07
that'll likely be the final ltsp and ldm for Karmic
13:08
<vagrantc>
stgraber: i haven't done any test builds, so if you juts want to go ahead and tag, that'd be fine too

vagrantc: I have test packages for both in my PPA if you want to test
13:26

stgraber: well, i have no urgent need to upload, so i'll do a test with my own processes.

Hi. I've been wondering about 3D and LTSP and/or thin clients in general ...I know that the LTSP server (or X client) is the one which handles the CPU and RAM, but what about the graphics?
13:34
E.g. is it possible to run 3D applications on LTSP clients and if so, which box needs the powerful graphic card.
13:36
<vagrantc>
thin client is where the graphics card matters
13:36
the server's graphics card is un-used.
13:36
at least from an LTSP perspective
13:39
<silver_hook>
vagrantc: Sooo, if I wanted to run 3D apps on LTSP, the set up should be such that the LTSP server doesn't need any graphic card whatsoever, but a decent enough CPU and RAM ...and on the thin client side I need neither disk nor a powerful CPU or RAM, but a decent enough graphic card.
13:39
Right?
13:40
<vagrantc>
i don't know if there's anything unusual about 3D apps.
13:41
the server just displays to the thin-client's hardware.
13:43
<silver_hook>
Do you happen to know if anyone successfully did something similar? Just as a heavy use case, would it be possible to play 3D games on thin clients with decent 3D cards but otherwise old hardware if the LTSP server was powerful enough?
13:44
<vagrantc>
in theory, sure. but i don't really know anything about 3D apps.
13:46
<johnny>
silver_hook, you're not going to get super good performance unless you use local apps.. which will require higher cpu and ram on the client
13:46
as you're be transferring 3d over the network
13:47
or rather graphics..but still..
13:52
<silver_hook>
johnny: "super good performance" qualifies as what?
13:55
<johnny>
decent framerates?
13:58
<silver_hook>
johnny: Meaning that a stock thin client would work with not-ultra-high-settings on e.g. Nexuiz to be usable?
14:00
<johnny>
i have no idea
14:00
you'll just have to try
14:05
<silver_hook>
Hmm, when I get the time I'll probably do. Although the thin clients that I have access to are made from waste HW :\
14:05
Thanks for explaining .]
14:05
:]

<tstafford_>
we use eeebox for thin clients... and they do quite ok running all the compiz effects and stuff
14:09pem725 has joined #ltsp
14:12
<vagrantc>
stgraber: so, if i select shutdown from the gnome logout menu, it should actually shut down the thin-client with the new ldm?
14:12
<stgraber>
if you have the right .desktop files in your /usr/share/applications on the thin client, yes
14:12
<vagrantc>
ah.
14:12
<stgraber>
I basically have a ltsp-shutdown.desktop and ltsp-restart.desktop files that add two entries to the gnome main menu
14:12
it's in my ltsp.karmic branch
14:13
basically two files in the debian/ directory
14:13
<vagrantc>
is it useful outside of ldm? shouldn't it go with ldm?
14:14
<stgraber>
well, it's useless without localapps
14:14
and localapps are in ltsp not in ldm
14:15
<vagrantc>
it's useless without ldm :)
14:15
there's no obviously correct place :)

Also, I never quite grasped the difference between LTSP and X server-client ...is LTSP just building on top of X as a separate server and client, or are the differences bigger?
14:19
<vagrantc>
well, my test build of ldm went fine. good enough for debian unstable, at least :)
14:19
silver_hook: LTSP is a collection of services and technologies put together in a way that provides a thin-client.
14:20
with a few small pieces of glue that provide some interesting functionality.
14:20
<stgraber>
vagrantc: pushed
14:21
<silver_hook>
vagrantc: And if I was just to run X servers on separate boxes from the X client, a thin client wouldn't be enough for the terminals/X servers?
14:22
I.e. I'd need a disk and more decent CPU and RAM?
14:22
<vagrantc>
silver_hook: i don't really understand your question (and the terminology around X client/server model really helps make everything confusing).
14:23vvinet has quit IRC
14:23
<vagrantc>
silver_hook: you can do what LTSP does by installing the appropriate packages on a disk'ed machine, if that's what you're getting at.
14:24
<silver_hook>
vagrantc: Yeah, I know the X server vs. client confuses me as well sometimes.
14:24
<vagrantc>
it confuses everyone.
14:24
<silver_hook>
vagrantc: OK. But if I use LTSP I don't need a disk on the terminal (i.e. LTSP clients) side, right?
14:25
<vagrantc>
this is one of those rare cases where i think it's better to describe what you mean more than use the existing terminology.
14:25
silver_hook: that's 99% of the point of LTSP, yes. :)
14:25
<silver_hook>
"terminal" sounds like a good way to describe it, I think :]
14:25
Cool :]
14:25
And what's the last 1%?
14:26
<vagrantc>
a few pieces that integrate stuff together like ltspfs and ldm.
14:27
<silver_hook>
And how secure is it?
14:28
<vagrantc>
well, booting over the network has some fundamental insecurities ... you're relying on the network to download your whole OS.
14:28
but setting that part aside...
14:28
by default (at least on debian/ubuntu) the connection between the thin client is run over ssh.
14:29
between the thin-client and LTSP server, that is
14:29
<silver_hook>
E.g. when I get an office (as an attorney), I'm considering to be using thin clients over secure connection and a hardened server to manage it. But I haven't checked yet if that's possible and how secure it is...
14:29
<vagrantc>
though parts of it, such as sound and local devices (usb sticks, CDs, etc.) still go unencrypted.
14:30
silver_hook: the weak point is the initial download.
14:30
i think gPXE may have some features for tightening that up a bit...
14:31tstafford_ has quit IRC
14:31
<vagrantc>
stgraber: well, ldm-trunk looks taggable to me. you want to handle the tarball, or should i?
14:32
<stgraber>
vagrantc: please do
14:32
<vagrantc>
heh. it's been a while ... i've mostly been riding on your coat-tails for upstream releases
14:33
<silver_hook>
vagrantc: Soo, basically it's still the LAN that has to be as secure as possible.
14:33
<vagrantc>
silver_hook: the problem is thin-clients basically turn on, and download whatever OS is offered to them.
14:34
silver_hook: through a dhcp request
14:34
silver_hook: so someone could just plug in a renegade DHCP server and give you whatever OS they wanted.
14:34
<silver_hook>
Hmm, would a very small disk (or better yet a ROM) with a checksum possibly solve this problem?
14:34
<vagrantc>
silver_hook: which could have malicious intent, and look just like the OS they're supposed to download.
14:34vvinet has joined #ltsp
14:35
<vagrantc>
silver_hook: you could load the kernel/initramfs from local media, but then you'd have to update the local media every time there was a kernel security update.
14:36
that's why it would be nice to have some sort of signing mechanism in gPXE. then you'd only have to update the local media when you change keys.

Hmmm, that's an option. ...But, anyway, I'm still a few years from that and I *really* should be studying for my exam :P ...so, thanks for all the info. It's been extremely helpful! I'll get back to LTSP when I actually have a practical use for it.
14:41
<vagrantc>
oh, i remember ... it's the /tmp/ldm-logout-action that's the problem.

14:43* silver_hook dreams of a FOSS-powered legal counciling and attorney office for FOSS :]
14:44

well legal aid manitoba uses it
14:45
iirc
14:45
but they don't do FOSS issues ..

vagrantc: On that topic, did you guys consider offering your services for money? I mean, hacking on LTSP in general for free, but building LTSP networks (to suit specific needs) and offering support to customers for money?
14:54
<vagrantc>
a number of businesses are built around LTSP
14:54
<silver_hook>
I imagine so, yes!
14:55
<johnny>
yes. people do.. but not ltsp as a project
14:55
as the project is a loosely knit group of people
14:55
<silver_hook>
Well, as a project that'd be hard to do ...but individuals from the project or joined together as a business — that could work.

In KDE e.g. there's the Ko Gmbh. that employs most of the bigger devs of KOffice and there's the KAB Gmbh. (or some similar name) that employs most of the KDE PIM hackers.
14:57
<johnny>
i think we are too far apart silver_hook
14:57
and something like ltsp requires in person work
14:58
it's not something you can really do remotely..
14:58
<silver_hook>
That's true.
14:59
<vagrantc>
wow. and i thought we did *tons* of work remotely :)
14:59
<silver_hook>
But then again, you can still make your own company and/or invite people who make money by implementing LTSP to be more active in the development.
14:59Ryan52 has quit IRC
14:59
<johnny>
vagrantc, but not the installs..
14:59
<silver_hook>
Yeah, I know I'm stating the obvious :P
14:59
<johnny>
silver_hook, people are making money off the installs
15:00
silver_hook, quite a few of the biggest problems facing usage of ltsp are not problems that ltsp can fix alone..
15:00
<silver_hook>
...and maintainance, I wouls assume.
15:00
<johnny>
they cross distro issues, x issues , kernel issues
15:00
<silver_hook>
s/wouls/would
15:00
<johnny>
for example.. there is still no standard way to do the read write filesystem on top of a read only filesystem
15:01
the kernel process has been stalled for years
15:01
<silver_hook>
:\
15:01
<johnny>
the main vfs guy just doesn't like the other designs.. so we're still waiting..
15:01GodFather has joined #ltsp
15:01
<johnny>
and openoffice has someodd pixmap issues that require knowledge only somebody who really really works on OOo can fix
15:01
most of the issues are just beyond the scope of network admins and gluers like us..
15:02
some of the issues couldbe influenced by monetary input.. but not that kernel issue..
15:02
for example..
15:02
3 different solutions have been discarded for inclusion so far..
15:02
<silver_hook>
True, but the more people CC to or vote on a certain bug or feature request, the likelier it is to be considered soon-ish...
15:03
<johnny>
no..
15:03
the problem is design that satisifes the maintainer
15:03
votes ain't gonna help
15:03
he already wants it..
15:04
now it just takes a super dedicated kernel hacker
15:04
the best ltsp could do is raise some money to pay for one..
15:04
<silver_hook>
That's the problem ...different methods work on different projects/people :P
15:04
<johnny>
sure.. and ltsp cut across so many projects
15:04
it's more likely for us tobe a way to funnel money to the people who can do the work on specific projects
15:04
most likely.. people who don't even use or care about ltsp at all
15:05
just somebody who would like to be able to afford working on generally intractable problems :)
15:05
<silver_hook>
Did you consider making a fundraiser and try to get in touch with business you know use LTSP and explain why the money is needed for a kernel coder?
15:05
<johnny>
i've talked to folks about it sorta..
15:06fotanus has quit IRC
15:06* silver_hook knows he again stated the obvious ....
15:06
<johnny>
but.. i know i don't have the time.. i only use ltsp for a lab of 3 computers :)
15:06
i can't afford to spend the time to organize that kinda thing.. i have other pressing issues
15:06
i've been trying to convince lns here to do something like that tho
15:06
but he doesn't seem to be around atm
15:06
<silver_hook>
Don't we all... :/
15:07
<alkisg>
!seen sbalneav
15:07
<ltspbot>
alkisg: sbalneav was last seen in #ltsp 3 days, 23 hours, 3 minutes, and 55 seconds ago: <sbalneav> Some work gets done at the BTS, but IMHO, it's more of a "team building" excercise than anything else.
15:08
<silver_hook>
In Cyberpipe I know we use LTSP to power about a dozen of terminals for our free cybercafe ...so I could poke around a bit, but I can't promise much success...
15:08
<johnny>
silver_hook, on a long enough timespan..many of the issues will be fixed for us :)
15:08
the kernel issue could be fixed soon
15:08
udev is gaining prominence leaving us to be able to ignore hal..
15:08
there's the new cuse (character user space filesystems)
15:08
plus all the new kernel graphics work..
15:08
etc..
15:09
<silver_hook>
Udev is supposed to make HAL obsolete? When did I miss that train??
15:10
<johnny>
almost a year ago
15:10
<silver_hook>
I thought they're mainly cooperating and slightly (for whatever reasons) overlapping technologies.
15:10
<johnny>
well it's not just udev
15:10
it's also devicekit (and devicekit-disks, devicekit-power)
15:10
<silver_hook>
Hasn't X.org just recently switched to HAL to handle its devices?
15:11
<johnny>
https://wiki.ubuntu.com/Halsectomy
15:11
alot of that work is happening in gnome itself, and many other distros
15:11
<silver_hook>
I know I wrote a HOWTO on it less then a year ago and it was pretty new stuff...
15:11
<johnny>
that's just the nicest collection
15:11
xorg will be using udev
15:12
hal did both too much.. and too little
15:12
<silver_hook>
Oh, well, I smell another HOWTO someday soon-ish then :P
15:12
<johnny>
it helped people figure out where things fit in the stack
15:12
<vagrantc>
silver_hook: yes, it recently switched to using hal, and it in the process of switching to udev.
15:12
<johnny>
now that they figured it out.. the need for such a complicated machine has died
15:13
<silver_hook>
johnny: How soon do you reckon X.org will start using Udev?
15:13
<johnny>
depends on the distro :)
15:13
i think fedora's xorg might already
15:13* vagrantc waves from the Debian camp
15:13
<silver_hook>
Meaning in Gentoo it's already possible :P
15:13
<johnny>
silver_hook, i do'nt know
15:13
fedora will use git snaps as "stable" while gentoo won't often

iirc anyways.. i used gentoo for 6 years
15:14
just recently switched to fedora on my main machine

15:14
<johnny>
hmm. .whoa it's been a year since i started using fedora now..
15:15
ah.. it is just now recently done
15:15
cool
15:15
exciting even..
15:15
<silver_hook>
johnny: That's true. Unless you use overlays, Gentoo doesn't promote snapshots unless they're absolutely needed.
15:16
<johnny>
plus fedora will include patches much quicker than gentoo if they are obviously destined for upstream.. as fedora folks are often the upstream

I liked HAL's XML configs better, but I guess writing Udev rules is not too hard either :P
15:16
<johnny>
of course gentoo did have to carry like 70 hal patches at one point
15:17
<silver_hook>
johnny: Also true. But I'm still sticking to Gentoo :]
15:17
<johnny>
yeah.. i just couldn't handle it anymore.. packages weren't up to date enough for all the effort it took to maintain
15:17
it was better originally..
15:17
<silver_hook>
...that is, when I get enough money to get a new laptop. My old one died a few weeks ago :\
15:17
<johnny>
but i feel like i learned enough..
15:17
so.. i don't consider my gentoo time a waste or anything.. because of it i can troubleshoot almost any problem.. on any distro :)
15:18
altho selinux was new to me when i switched to fedora
15:18

Oh, well, I try to help with submitting bugs, testing and even writing ebuilds, when needs be

Hi, I've installed a LTSP system on my Debian 5.0. But when I start the thin-client and try to login, it says that this computer can't login. Someone knows why?
15:18
<silver_hook>
Anyway, I really shouldn't hog up the channel and continue studying.
15:18
<johnny>
bernardo0cd0, that user exists on your server?
15:19
<vagrantc>
bernardo0cd0: probably run ltsp-update-sshkeys on the server.
15:19
bernardo0cd0: but what is the specific error message?
15:19
<silver_hook>
Thanks for your patience and keep up the cool work, guys!
15:19
Oh!
15:19
<bernardo0cd0>
johnny, yes, on the server the login occurs normaly, even with ssh
15:19
<silver_hook>
I *do* have some news you might like.
15:19
<johnny>
silver_hook, i do somewhat maintain the gentoo port of ltsp
15:20
silver_hook, i'd really like a gentoo virtual machine on somebody who has good hardware..
15:20
let me know if anybody wants to share a machine so i can build ltsp chroots all day :)
15:20
<bernardo0cd0>
vagrantc, i already tried that. The GDM says (in portuguese) that THIS computer can't connect on the server. if I try in the terminal (switcing the X) it simply says "Login Incorrect"
15:20
<silver_hook>
johnny: In Cyberpipe we have a relatively powerful Xen server ...I could ask.
15:21
<vagrantc>
bernardo0cd0: are you sure it's GDM ?
15:21
<johnny>
silver_hook, it would be helpful... i'll of course need other testers to help test boot capability
15:21
<vagrantc>
bernardo0cd0: by default, it uses a login manager called LDM
15:21
<johnny>
but at least if i can build .. i can figure out the deps and everything.. keep stuff working overtime
15:22
<silver_hook>
I was recently on a (Business) Linux conference and Jon "Maddog" Hall was there and mentioned that he's just starting a new project called Cauã which incudes a lot of Linux thin clients.
15:22
<bernardo0cd0>
vagrantc, well, that's new for me. But he shows the LTSP background, so prabably is the LDM that you said.
15:23
<vagrantc>
bernardo0cd0: how did you create the LTSP chroot?
15:23
<silver_hook>
johnny: They mainly use Debian in Cyberpipe, but there are a few Gentoo enthusiasts. At least on Debian you'd probably get testing done ;)
15:23
<bernardo0cd0>
with the ltsp-build-client
15:23
<vagrantc>
bernardo0cd0: no special arguments or options?
15:23
bernardo0cd0: ltsp server and ldm server are the same machine?
15:24
<bernardo0cd0>
yes, but only to set the base-folder and arch, and it is on the same machine
15:24
<vagrantc>
ah, you'll have to configure ltsp-update-sshkeys properly.
15:24
<bernardo0cd0>
isn't just run that?
15:24
<johnny>
silver_hook, nah.. i really need gentoo.. so i can build chroots..
15:24
<vagrantc>
changing the base folder isn't well supported.
15:25
<bernardo0cd0>
and if I create a symbolic link?
15:25
<silver_hook>
About project Cauã: it's not public yet, but be sure to keep your eyes open! When/if it starts you'll have like half Brasil using LTSP!
15:25
<vagrantc>
bernardo0cd0: yeah, try creating symbolic links in /opt/ltsp/ to wherever your base dir is
15:25
bernardo0cd0: that's the simplest way to handle that
15:25bieb has left #ltsp

johnny: Getting a VM with Gentoo is no problem ...I'm just saying that the LTSP server in Cyberpipe is running Debian AFAIK.
15:26
There's a dedicated Xen machine and it already runs at least one Gentoo VM.
15:26
<bernardo0cd0>
ok, i created, all that I have to do is restart the thin-client, isnt any command to apply or something like that?
15:26
<johnny>
if you could ever test it that would be helpful too..
15:27
<silver_hook>
Drop me an e-mail to matija[döt]suklje[ãt]rutka[dȯt]net and I'll try to patch you through.
15:27
<bernardo0cd0>
ok, I will test, hang up... :D
15:27
<vagrantc>
bernardo0cd0: re-run ltsp-update-sshkeys after creating the symlinks, and then reboot the thin client.
15:28
<silver_hook>
johnny: The problem with testing is that Cyberpipe's LTSP server runs on Debian and, personally, I only have a (dead) Gentoo laptop :P
15:28
I'll see what I can do though.
15:28
Have to run now ...food's ready! :D
15:28
Drop me an e-mail, OK?

yes, has only some days
15:41
<vagrantc>
heh. i'm already rusty on lenny, focusing on newer versions lately.
15:42
bernardo0cd0: try setting SCREEN_07=ldm and SCREEN_08=shell in lts.conf, and reboot a thin client ... that gives us more options for debugging.
15:42
<bernardo0cd0>
hehe, the problem that my father will kill me if the server go down, so the focus is stability
15:42
i already have access to the shell, but i can't login on it
15:43
with Ctrl+Alt+F1 I can easily access the linux terminal
15:43
<vagrantc>
that's why i said to set SCREEN_08=shell ... gives a root shell without a password.
15:43
<bernardo0cd0>
oh, that's great :D
15:43
<vagrantc>
obviously to be turned off after debugging.
15:43
<bernardo0cd0>
ok, wait a minute
15:44
only to know, I have only 2 lines on my ltsp.conf
15:45

bernardo0cd0: please paste your lts.conf to the pastebot
15:45
<ltsppbot>
"bernardo0cd0" pasted "ltsp.conf" (2 lines) at http://pastebot.ltsp.org/575
15:46
<bernardo0cd0>
ok, it's added
15:46
<vagrantc>
note that it's lts.conf, *not* ltsp.conf
15:46
so those are completely ignored. and those options won't do anything anyways :P
15:47
<bernardo0cd0>
hmm, ok, i'm completely lost :D
15:47
<vagrantc>
bernardo0cd0: do you have an /opt/ltsp/i386/etc/lts.conf ?
15:47
<johnny>
vagrantc, why don't we change it to ltsp.conf? :) or allow both to work somehow ? :)
15:47
<vagrantc>
johnny: i've wondered about that from time to time ...
15:48
johnny: there's just so much documentation out there...
15:48silver_hook has left #ltsp
15:48
<johnny>
vagrantc, symlink then?
15:48
<vagrantc>
johnny: and you've got the tftp downloads of lts.conf, in addition to the normal reads...
15:48
<ltsppbot>
"bernardo0cd0" pasted "lts.conf" (13 lines) at http://pastebot.ltsp.org/576
15:49
<bernardo0cd0>
ok, it's in lts.conf where i have to add the SCREEN line?
15:49
<vagrantc>
bernardo0cd0: could you comment out LOCALDEV, SOUND, NBD_SWAP and LDM_DIRECTX ?
15:49
bernardo0cd0: and add the two options i mentioned?
15:50
localdev and sound are default.
15:50
<johnny>
we could try to download both for a time.. but that would be annoying
15:50
<vagrantc>
so that shouldn't matter.
15:50
johnny: i proposed to download a tarball or some other archive file that contains all the files to unpack into the chroot ...
15:50
johnny: but that was shot down.
15:50
<bernardo0cd0>
ok, so i have to comment all the file, and letting only the screen line active?
15:50
<johnny>
all files?
15:51
bernardo0cd0, make sure [default] is not commented
15:51
<vagrantc>
johnny: just modified files.
15:51
<johnny>
for exaxmple?
15:51
<vagrantc>
johnny: or likely to be modified files.
15:51
johnny: say you want a custom screen script in the chroot ... just add it to the tarball.
15:52
johnny: by default, it'd only contain lts.conf, but you could add additional files to it and only have to download a single file.
15:52
<ltsppbot>
"bernardo0cd0" pasted "New lts.conf" (14 lines) at http://pastebot.ltsp.org/577
15:52
<vagrantc>
bernardo0cd0: add SCREEN_07=ldm
15:52
bernardo0cd0: and then reboot your thin client.
15:53
<bernardo0cd0>
ok, i've added
15:53
let's restart
15:55
vagrantc, ok, it continues not logging in but now i have the root terminal
15:55
<vagrantc>
bernardo0cd0: is there a /var/log/ldm.log ?
15:56
<bernardo0cd0>
hmm, i should check that by the server ou the client terminal?
15:56
*or
15:56
<vagrantc>
bernardo0cd0: on the thin client
15:56
<bernardo0cd0>

stgraber: just uploaded ldm 2.0.48, should hit http://incoming.debian.org soonish.
15:58
<bernardo0cd0>
ha! the problem is the ssh keys
15:58
it says that the anthencity of the server can't be established, but i already ran the ltsp-update-sshkeys
15:58
<vagrantc>
you have to teach ltsp-update-sshkeys to use your weird location.
15:59
or just re-install in the normal location
15:59
<johnny>
can't you just mv the chroot?
15:59
why reinstall?
15:59
<vagrantc>
could just move the chroot, too.
16:00
<bernardo0cd0>
no, i installed the system with sctrict partitions for /home, /var, /usr,etc... so the /home is the unique that has space for that
16:01
<johnny>
them a symlink will work
16:01
then*
16:01
/me doesn't recall the script checking for such things
16:01
<vagrantc>
bernardo0cd0: you could bind-mount /opt/ltsp to your current directory.
16:02
i.e. mount --bind /some/crazy/location/for/ltsp /opt/ltsp
16:02
and stick it in fstab.
16:02
<bernardo0cd0>
the symlink is (theorically) working
16:02
<vagrantc>
bernardo0cd0: i thought you said it wasn't working?
16:02
bernardo0cd0: what's your actual symlink?
16:02
ls -l /opt/ltsp
16:03
<bernardo0cd0>
i didn't tested run ltsp-update-sshkeys after creating the symlink
16:04
<vagrantc>
well, that'd break it for sure.
16:05
<bernardo0cd0>
vagrantc you are my hero!
16:05
it's working!
16:05
<vagrantc>
heh.
16:05
<bernardo0cd0>
thanks!
16:05
<johnny>
he is all our hero
16:05
not just yours.. don't take him from us :)
16:05
<vagrantc>
bernardo0cd0: so, what can we learn here? use the defaults :P
16:06
<bernardo0cd0>
i'm not a default man, hahahah
16:06
<vagrantc>
we really also should do better to support non-default base paths, because it comes up often enough.
16:06
<johnny>
vagrantc, yes.. i've seen that :(
16:07
<vagrantc>
removing support would be bad ... though maybe a warning in the help output and man pages...
16:07
<bernardo0cd0>
why not simply create a config file on /etc/ltsp and inside have a line like that: YOUR_WEIRD_LOCATION="/weird/location"?
16:08
so all the scripts will use that varbiable
16:09
<vagrantc>
yeah, we need an /etc/ltsp/common.conf
16:09
or some such
16:09
<bernardo0cd0>
can have other lines too, like default arch and so....
16:10
one more question, for what is the image created on /opt/ltsp/image ?
16:10
<vagrantc>
bernardo0cd0: for using NBD instead of NFS
16:10
<bernardo0cd0>
hmm, so i don't need that?
16:10
<vagrantc>
bernardo0cd0: debian uses NFS by default.
16:11
bernardo0cd0: nope. never need to run ltsp-update-image

other thing, the /home on the client is the /home on the chroot or the /home of the server?
16:18
<auctmore>
Hi. It has been a while since I last contacted this channel. I am using older versions of LTSP with much success in my Belgian classroom for about 9 years now. Only a week ago I switched servers from SuSE 9.x with LTSP 4.x to K12Linux (Fedora Core 10) with LTSP5. The basics work fine but I experience som minor glitches.
16:19
That is: "... somE minor glitches"
16:20
<vagrantc>
bernardo0cd0: no, /home is basically /opt/ltsp/i386/home
16:20
bernardo0cd0: on the thin client
16:21
bernardo0cd0: typically, you just use the thin-client to log into the server, and all applications, file access, etc. is done on the server. merely displayed to the thin client, like an extra monitor/mouse/keyboard for the server.
16:23
<auctmore>
glitch1: although I changed XkbLayout in lts.conf to "be" the login screen from LDM is still in Qwerty layout. How come?

Since a few weeks I am using K12Linux instead of SuSE 9.x and LTSP 4.x, but I am not an authority!!
16:31

ltsp4 doesn't use ldm
16:31
oh.. k12 oops
16:32
i don't know.. that's not a bug in ltsp as far as i know auctmore
16:32
i have my terminals open that long before people login
16:32
it could be some other bug, you'll have to drop to console and see if if kernel panics happen, or enable syslogging
16:34

Okay I'll reboot the terminals every now and then for the time being until I figure out what's happening. Thanks.
