Hi. I'm using LTSP on Gutsy on Ubuntu, but it says "Workstation is not authorised to logon" when I try to log in. I tried doing an ltsp-update-sshkeys, but it didn't seem to work
02:32
do I have to rebuilt the image too?
02:36
ah yes, I had to :)

highvoltage, can you name alternative solutions to ltsp? I want to do something like a comparative

hello, can you name alternative solutions to ltsp? I want to do something like a comparative
03:11plamengr has joined #ltsp
03:12
<cyberorg>
gonzaloaf, there is no alternative, but you can check out vnc, nx, citrix
03:12
<gonzaloaf>
cyberorg, I mean apps that try to do the same thing :p
03:13
cyberorg, so you know any propietaries?
03:13
<cyberorg>
gonzaloaf, vnc, nx, citrix
03:13
<highvoltage>
gonzaloaf: LTSP is pretty much one-of-a-kind at this stage.
03:14
gonzaloaf: you can compare other terminal-like systems, but it would be a bit of a strange comparison
03:14
<gonzaloaf>
highvoltage, I know... I just need to name anothers to conclude that LTSP is the right app to use

cyberorg; i want to install kiwi on a 64bit opensuse 10.3, what should i look out for?
03:57
<cyberorg>
doggkatcha, it is 32bit only for now :( it would be a lot of manual work on 64bit, we will do it for that once we have 32 ironed out
04:00
<doggkatcha>
cyberorg; i can get 4.2 to work on 64bit sled, but the gdm locks up after a while, any ideas?
04:01
<cyberorg>
doggkatcha, nope, haven't ran 4.2 in a long time

cyberorg; no way to build a 32 bit image with kiwi?
04:04
<cyberorg>
doggkatcha, we are building only 32bit
04:09
doggkatcha, technically there shouldnt be any difference in running 32bit image to connect to 64bit server, as we are using ssh for Xsession
04:29
<doggkatcha>
cyberorg; i'm going to try out it anyway and let
04:29
let you know how it goes
04:31

doggkatcha, cool :)

Morning all
07:52
<klausade>
when using LDM_USERNAME=, must I also set the password in cleartect via LDM_PASSWORD, or is there some other way?
07:57mikkel has quit IRC
08:01
<sbalneav>
That's how you do it.
08:01
password in cleartext.
08:02
<klausade>
sbalneav: ok. for terminals in a library that should be ok.
08:03
<sbalneav>
I think you should be able to chmod 600 the lts.conf file
08:04Uranellus has joined #ltsp
08:05
<Uranellus>
hello, is there a kdm theme for ldm ?
08:05
<klausade>
sbalneav: small help, as long as anybody can mount /opt/ltsp/i386
08:06
sbalneav: but having LDM_USERNAME and LDM_PASSWORD contitues "(very) ease of use", and you can't combine that with security anyway.
08:07
<sbalneav>
Correct.
08:07
Which is why I don't agree with _USERNAME and _PASSWORD anyway. However, it's a feature people seem to want, so I provide it.
08:07
Caveat emptor
08:08
<klausade>
sbalneav: they asked for it ....
08:12
<highvoltage>
sbalneav: I installed LTSP today for the first time in a long time (gutsy). WOW!
08:12
<sbalneav>
Like it?
08:12
<highvoltage>
a lot. besides for some tiny problems it's really slock
08:12
*slick
08:13
<sbalneav>
Tiny problems?
08:13
Do tell.
08:13
Wait'll you see what I've worked up for local apps. I've got that licked in the last few days.
08:13
<highvoltage>
the only thing that bothered me was that the password prompt doesn't dissapear when authentication takes place, and that authentication takes a few seconds
08:13
sbalneav: WOW!
08:13
<sbalneav>
Ah, that's a byproduct of the scripted greeter.
08:13
<highvoltage>
sbalneav: that will make me very, very excited
08:14
<sbalneav>
I'll maybe touch that up a bit next go-round.
08:14
<highvoltage>
sbalneav: I think that scripted greeter is good! it's very fast, way better than the old LDM
08:14
<sbalneav>
It does, however, now give you status messages, so that's a HUGE improvement.
08:14
<highvoltage>
(except that it segfaults now and again)
08:14
<sbalneav>
reeeeealy?
08:14plamengr has joined #ltsp
08:15
<sbalneav>
I haven't seen any segfaults, so if you run into one, file a bug.
08:15
so's I can fix it.
08:15
<highvoltage>
yep, when I press the power button on my computer, the system doesn't shut down, I see a quick Segmentation Fault message, and then LDM comes back
08:15
ok, I'll do so
08:15
<sbalneav>
ah, ok.
08:15
I don't think we ever added in the acpi-scripts to handle power buttons on thin clients.
08:15
<highvoltage>
but besides that, it's really nice. LTSP is getting to a very mature point
08:15
<sbalneav>
So that's quite possible.
08:15
<highvoltage>
aaah
08:16
I'll suggest fixes in the bug report then.
08:16
<sbalneav>
yeah
08:16
then we can get it in for hairy.
08:16
We'll have localapps in hairy as well.
08:18
<Uranellus>
how do I change the language on the client to german and tell it to use a german kb layout? (using ltsp 5)

Uranellus: Check in the Edubuntu Handbook, there's some XBK_ options you can put in the lts.conf file.
08:26
highvoltage: Have you been reading the updated handbook?
08:27
<highvoltage>
sbalneav: nope, where can I find it?
08:28subir has quit IRC
08:29
<sbalneav>
highvoltage: Ubuntu help centre
08:29
The little red questionmark :)
08:29
I'm assuming you're running edubuntu.
08:30* highvoltage looks
08:30
<highvoltage>
sbalneav: just Ubuntu for our current customers
08:31
<sbalneav>
edubuntu-docs package, if you need to install.
08:31
<highvoltage>
ok

<Solv>
I will need to do a new install of a small ltsp system soon, which I will only be able to remotely adminster, and the local adminster would be a linux novice but not a computer/network novice. Would edubuntu be the easiest option for them to learn, or k12ltsp? I haven't tried either...I just installed 4.2 manually over fedora
09:01
so any opinions would be appreciated
09:12jammcq has joined #ltsp
09:15
<highvoltage>
sbalneav: ltsp-server still suggests nfs-kernel-server and sdm
09:15
sbalneav: is that right?
09:16
(I mean, should it still be like that?)
09:16
<ogra>
yes
09:17
it moved from being a dependency to being a suggestion
09:17
you can use nfs if you like
09:17
we're not that evil :)
09:17
<jammcq>
only a little evil
09:18
<ogra>
yeah, a bit :)
09:18
<highvoltage>
ok :)
09:18
<Solv>
can I get the same admin tools available in edubuntu in kubuntu without too much mucking around?
09:18
<ogra>
Solv, which ones ?
09:18
<Solv>
like the gui client manager
09:18
<ogra>
sure
09:18
but there is no QT frontend (yet)
09:18
<Solv>
it's all in the univers repo?
09:18
<ogra>
nope, in main
09:18
<Solv>
so it will just look a little strange
09:18
<ogra>
you want thin-client-manager-gnome
09:19
<Solv>
okay cool
09:19
<ogra>
it will pull in the rest
09:19
<Solv>
i imagine ltsp in ubuntu is by far the easiest way to teach someone new about ltsp and how to administer it?
09:20
i'm an old 4.2 user...haven't made the leap yet (pity no other distros support 5.0)
09:20
ogra, so the ltsp-kde-tools package is still under development?
09:21
<ogra>
i'm not aware of such a package
09:21
<highvoltage>
Solv: I've installed LTSP in Ubuntu Gutsy today for the first time in ages
09:21
<Solv>
highvoltage, working well for you?
09:21
<highvoltage>
Solv: and LTSP is indeed very easy to install, and I believe it's become much easier to administer as well
09:21
Solv: yep, only in early stages of testing. I used to love LTSP 4.2 too
09:22
<ogra>
Solv, thin-client-manager is designed to work with different frontends but nobody stepped up for a KDE variant ... beyond that there are no gui tools yet
09:22
<Solv>
I tried to install it in kubuntu 6 months back...couldn't get local devices to work...ran out of time...so i keft it
09:22
<highvoltage>
Solv: this is, in my opinion, even better than the 4.2 release.
09:23
<Solv>
highvoltage, great...well at the end of the year when my students move on I can reformat the server and have some fun
09:23
<highvoltage>
Solv: what do you have on there at the moment?
09:23
<Solv>
tis a pain in the arse to upgrade from fedora with ltsp 4.2 while they all have their files on their and use it everyday
09:23
fc5
09:24
and it's becoming a problem...because upgrades are becoming scarce
09:24
it is a major issue with a distro that has such a fast release cycle, and that is not easily upgraded without doing a fresh re-install...
09:25
actually that's another point....can one easily upgrade ubuntu releases internally, without re-installing from disc? That would make it much more attractive as well
09:26
?
09:27
<highvoltage>
ogra: I might have asked you before, but is there a reason why i386, PPC, IA64, etc squashfs images can't be packaged?
09:27
Solv: yep, you can upgrade from release to release quite easily
09:28K_O-Gnom has joined #ltsp
09:28
<Solv>
highvoltage, thanx mate
09:28
<ogra>
highvoltage, me being busy with other stuff :)
09:28
<highvoltage>
Solv: we used to use FC in a lot of schools here in South Africa, but upgrades became to cumbersome for us, so we switched to Ubuntu, and it's been much better
09:28
<ogra>
we should have a client-image-$(arch) package
09:28
<highvoltage>
ogra: aaah, great. so it's not an issue, policy speaking
09:29
ogra: mind if I try to make some time to look at it? and if I could put something acceptable together, would you mind sponsoring a package?
09:30
(I realise it's too late for Gutsy)
09:31
<ogra>
i wouldnt mind indeed :)
09:31
make it a downloader like the flashplugin-nonfree one
09:31
<highvoltage>
ok, that's a good idea
09:31bobby_C has quit IRC
09:31
<highvoltage>
because the img would probably need to be build on a canonical build server?
09:31
*built
09:32
<ogra>
doesnt need to, no
09:32
if you have a downloader it doesnt matter from where thats coming
09:32
<highvoltage>
ok, where should I initially store the images?

ogra: you are a genius!
09:37
ogra: I was just about to ask on -motu how I would handle the licensing for a tarball that contains a whole system...
09:38
ogra: then I realised the package itself probably won't need the licensing for all the parts of the tarball, since it downloads the tarball seperately
09:38
ogra: am I right?
09:38
<ogra>
right
09:39
well, you should make sure that the tarball contains stuff thats redistriubutable over the web, so the license still matters indeed
09:39
but not for the downloader package
09:40
i.e. the most beautiful and nicest downloader wouldnt make all the win32codecs packages any more legal ...
09:40
if the content can get you into jail it wont help to have a gpl'ed downloader for it ;)

[ogra]:: you know how can I analyze if my ltsp connection is having to much packet loss ?
11:40
<ogra>
ping with a big packetsize ?
11:41
<cdealer>
I dont think this will be enough =(
11:42
[ogra]:: I want to know if connected through a client could cause more packet loss them a direct connection (without passing through the ltsp server)
11:43
<ogra>
what do you mean ?
11:43
you kow that you are working on the server and the client is only use for display and input/OUTPUT ?
11:43
*USED
11:43
whoops
11:45
if yu would have packet loss to the client that would result in a broken sluggish desktop but it wont affect your internet connection or so
11:45Avatara has quit IRC
11:45
<sbalneav>
cdealer: The only way you should be getting packet loss is if you've got bad networking equipment.
11:45Daggett has quit IRC
11:45
<ogra>
stuttering audio and stuttering mouse would also be a symptom
11:45
<sbalneav>
right
11:46
<ogra>
so what exactly do you see ?
11:46
or miss
11:47
<sbalneav>
Right, I guess the question is: what's the symptom that makes you think you're losing packets?
11:48
<cdealer>
well
11:48
what happens is the we have windows in our clients today and we want to go to linux
11:48
so we are making some tests
11:48
and
11:49
the users must use a java applet app through the webbrowser
11:49
this applet works great in both, linux and windows
11:49
<ogra>
so your limitation is server ram and CPU
11:50
unlikely that the network will have any impact on it
11:50
<cdealer>
what is strange is that the aplect conection closes more often on linux them windows
11:50
<ogra>
that can as well be a bug in the app or the java vm etc
11:50
<cdealer>
in my point of view there are no problem on ltsp, but for my boss this is a new land and he are blaming the connection loss because of linux
11:50
<sbalneav>
Could be a bug in the software, or vm
11:50
DOH
11:51
<ogra>
the network is surely the last ressource here you should suspect
11:51
<cdealer>
[sbalneav]:: ok, it could be, but.... the problem only occours here (we are remotly connected to other state)
11:52
in the other state the linux isnt having any problem but they dont use ltsp (what for me doesnt matters)
11:53
well, I think that you have nothing to do with this... sorry for I being bottering you with this, is that im lost and I dont want to see this implamantation going wrong
11:53
<ogra>
so they use the identical distro and java setup over there ?
11:53
but no ltsp
11:54
(how else would you be able to even remotely compare)
11:54
<sbalneav>
Simplest would be to use something like Wireshark or tcpdump to see whats going on in the network if you want, but I'd check .xsession-errors, or wherever the java-vm logs it's stuff and see if it's issuing any errors.
11:54
<ogra>
yeah
11:56
<cdealer>
must be a connection problem, because the java console dont report anything, only the applet that reports a error saying that the connection was lost and bla blla... now i think that i must analise the two ends of the connection
11:56
<sbalneav>
Maybe your firewall is blocking ports that the java app is expecting to use.
11:56
That'd be the most likely place to start looking.
11:57
<cdealer>
[sbalneav]:: the firewall is already open for this connection... this error occurs after some time, like 1, 2 hours of use
11:57
<sbalneav>
Need SO_KEEPALIVE then on something?
11:58
<cdealer>
[sbalneav]:: what? this is a new information for me... are you saying on the firewall ?
11:59
we are going to use iperf to see if we found the problem
