<alkisg>
I think ldminfod could be modified to become 'ltspinfod', a web-based daemon that gets the client mac/ram/cpu/ip etc and returns both the ldminfod info and the lts.conf info.
00:33
Making a small web server in python is easy: http://fragments.turtlemeat.com/pythonwebserver.php
00:34
It would use the same port, 9571. And of course we could continue supporting the old lts.conf way of doing things for some time, for compatibility..
00:34
Would anyone care to see an example implementation for this?
00:36
It could even be used to "mark down" some things on the server concerning the client, e.g. which nbd image to serve
00:36
So, the same port could be used for *all* nbd images
00:36
That would save us from all the nbd-port trouble, and make any IANA applications easier

<vagrantc>
alkisg: ltspinfod already existed and did different things... but otherwise very interesting idea.
01:12
<alkisg>
vagrantc: I mean to replace ldm-server with a more generic ltsp-server
01:12
(forgot about the name change)
01:12
Ah sorry I didn't know that
01:13
<vagrantc>
i don't want to move ldminfod into ltsp-server, as ltsp-server pulls in all sorts of dependencies unrelated to being an application server.
01:14
<alkisg>
I don't think it will need any dependencies. So it can even be a different binary package
01:15
(or it can stay in the ldm package...)
01:15
The main difference will be that it be called from the initramfs or wherever else the client tries to get lts.conf
01:16
<vagrantc>
if it's broader than ldm, it should move out of ldm, but i don't want to loose the ability to be able to install ldm-server and only pull in dependencies relevent to an application server.
01:16
<alkisg>
(if it gets implemented) it will replace lts.conf completely, and make getltscfg obsolete
01:17
As the getltscfg functionality will move to the server
01:17
<vagrantc>
so, in that sense, it seems like it might make an additional piece of code above and beyond ldminfod.
01:17
alkisg: how will that scale to thousands of thin clients hosted by a single server?
01:17
<alkisg>
I don't think it's any different from ldminfod in terms of scalability
01:18
<vagrantc>
ldminfod only hits it once per login, as opposed to every time it needs to look up configuration
01:19
<alkisg>
The client only gets lts.conf a couple of times on each boot
01:19
And we could add/merge the "login time" one
01:19
<vagrantc>
i like the idea of a single port to figure out which nbd image to use and whatnot.
01:19
<alkisg>
I mean, the client would do: wget server -O /etc/lts.conf
01:20
It would cache the result, it won't hit the server every time
01:20
<vagrantc>
alkisg: ah, when you say completely obsolete getltscfg ... i thought you were proposing something else.
01:20
<alkisg>
vagrantc: that new lts.conf will be a directly sourcable file
01:21
<vagrantc>
then we should maybe not call it lts.conf ... but ltsp.conf :)
01:21
<alkisg>
OK
01:21
I mean that it will only contain info for that specific client
01:21
<vagrantc>
if it breaks compatibility, may as well fix that old bug.
01:21
<alkisg>
Both lts.conf info, and ldm-server info
01:22
<vagrantc>
i'm not convinced that's a good idea yet...
01:22
<alkisg>
Why?
01:22
I think it's a good idea to know the client mac/ip etc before answering with ldm-server
01:23
E.g. the admin might want to blacklist some clients from using a specific server
01:23
Why use a different port/program/configuration interface for a similar set of settings?
01:24
<vagrantc>
if it's done without breaking compatibility, i guess that's cool. but we've already broken ldminfod compatibility at least twice now
01:24
without discussion
01:24
so here's the discussion :)
01:24
<alkisg>
Heh
01:25* alkisg looks at what ldminfod returns...
01:25
<vagrantc>
i.e. i'd like an older chroot to be able to get information from a newer server
01:26
<alkisg>
Ugh sucks. That would be better if it was a shell-sourcable output
01:26
<vagrantc>
suppose so.
01:26
<alkisg>
OK, we could do that
01:26
<vagrantc>
but it at least ignores fields it doesn't know about
01:26
<alkisg>
We could `post` a different output if the client doesn't send a mac/ip/ etc
01:26
<vagrantc>
so it's easy to not break future compatibility
01:27
that's true...
01:27
<alkisg>
The client could also send some kind of version
01:28
E.g. wget server:9571?mac=xxx&ltsp-version=xxxx
01:28
<vagrantc>
but we'd also want a newer chroot to be able to handle the output from the older server
01:28
<alkisg>
So we could check if version=null, then return the old style output
01:29* alkisg looks at ldm-trunk/screen.d/ldm ...
01:29
<vagrantc>
if we want forwards and backwards compatibility... it seems better to just implement something new.
01:29
on a different port...
01:30
<alkisg>
Hmmm where is /var/run/ldm/$SRV parsed from?
01:31
<vagrantc>
src/ldminfo.c
01:31
hah!
01:32
" What should happen here, for gutsy+1, is ..."
01:35
alkisg: well, i'd best turn in for the night.
01:35
alkisg: i expect all sorts of crazy ideas from you by the time i wake up. :)
01:35vagrantc has quit IRC
01:37
<alkisg>
Heh
01:38
Yeah, on second thought, it might be better to just implement something new. HTTP GET and POST would break compatibility anyway...

When inserting a hires pictures in a OO document , The thin clients tend to crash ( you get logged out and your back at the login screen). Is this a issue with pixmaps and low ram on the thin client?

Hi, I heard that 5.2 has better support for Fat Clients, can someone point me at a howto on setting up a fat client (preferrably for Ubuntu Karmic)? Sounds like just what I want to do.

<alkisg>
Heh, the new http://xkcd.com/ is fun :)
06:48
fasaxc: I plan to write such a how to in the next days... pem725 just did it yesterday for Karmic, so he might be able to help you as well.
06:49
Appiah: how much ram does that client have?
06:52jammcq has quit IRC
06:56
<klausade>
Appiah: how much ram, and what kind of videocard?
06:57
<fasaxc>
thanks alkisg, if it helps, I tried using the older howto at https://help.ubuntu.com/community/UbuntuLTSP/LTSPFatClients but hit a couple of snags that I couldn't seem to work around. Namely, installing nfs-common failed with an error about starting statd and the LDAP config stage seems to have changed a lot (the apt-get command asked a lot of questions that I couldn't answer)
06:58
<alkisg>
fasaxc: erm, scratch all that and start over :D
06:58
The new way has absolutely nothing to do with that page
06:58
You don't need nfs nor ldap
07:00
OK, I should probably make that how to today. Do you have time to test as I write it, to verify that it works?

07:36
<fasaxc>
yep, karmic
07:36* alkisg starts writing the how-to, I'll have something ready in 15'.
07:37
<fasaxc>
cool, I've put the PPA in
07:37
<alkisg>
fasaxc: is the command `add-apt-repository` preinstalled in karmic?
07:38
<fasaxc>
I seem to have it so I think so
07:38
<alkisg>
OK
07:39
<Comete>
could anyone confirm that this bug is stil here at reboot with ltsp 5.2 ?
07:39CAN-o-SPAM has quit IRC
07:40
<alkisg>
Comete: you need to update the chroot. Updating the server is not enough.
07:40
<Comete>
i have still no sound on my thin clients too
07:40
alkisg: i did it without success
07:41
alkisg: i rebuild the chroot and then updated it
07:42
and the squashfs error is still here
07:42
<alkisg>
Comete: karmic?
07:42
<Comete>
yes
07:42
<alkisg>
You need to put stgraber's ppa *in the chroot* and update again
07:42
<Comete>
alkisg: yes that's what i did
07:46
another thing gcompris is very slow, unusable, but maybe is it due to my sound problem...
07:47
sound card is well detected on thinclients
07:48
i have even heard a sound on one of them when opening a session, but i cannot reproduce this now... strange...
07:49
i don't know how to solve this problem
07:50
my server doesn't have a soundcard but i think that's not where the problem is

but gcompris 9.0 still slow

fasaxc, pem725: Here's a quick how-to for fat clients, both for Lucid and Karmic. It'd be nice if you could check its validity: https://help.ubuntu.com/community/UbuntuLTSP/FatClients
08:14
<fasaxc>
will do...
08:15mordocai has quit IRC

<Comete>
where should i put lts.conf, i've tried in /var/lib/tftpboot/ltsp/i386/ but it's seems to have no effect
08:18
<alkisg>
Comete: what do you get with: sudo chroot /opt/ltsp/i386 dpkg -l ltsp-client ?
08:21
<Comete>
ltsp-client 5.2-0ubuntu2~ppa1~karmic1
08:22
<alkisg>
Comete: and I suppose you run ltsp-update-image and ltsp-update-kernels, right?
08:22

<Appiah>
klausade: well its mostly HP T5530 , I think they 64mb ram
08:23
and Via videocard
08:24
<Comete>
alkisg: no because i rebuild the chroot, should i do it ?
08:24
<alkisg>
Appiah: with 64MB RAM you'll definately need swapping
08:24
<Appiah>
alkisg: and no swap = crash ?
08:24
<alkisg>
Appiah: NBD swapping was broken in karmic and maybe in jaunty too, so you'd need some patches from ltsp-trunk to make it work
08:24
Appiah: pretty much :)
08:25
<Appiah>
I thought the swapping was working ..
08:25
<alkisg>
Comete: how did you add stgraber's repository in the chroot?
08:25
<Appiah>
its a Jaunty install so I guess it could be that
08:25
so if we switch to PPA all will be well? :)
08:25
<alkisg>
Appiah: nope. We fixed it after 5.2... :(
08:26
<Comete>
alkisg: cp /etc/apt/source.list /opt/ltsp/i386/etc/apt/
08:26

08:26
<alkisg>
Appiah: you could just change a specific line, do you want me to look for it?

as it is said in the documentation
08:26

alkisg: would be nice, I could try it and report back if it works
08:26
<alkisg>
Appiah: are you seeing any swap files in /tmp/* ?
08:26
<Appiah>
sorry I dont have access to ltsp install atm
08:27
<alkisg>
Comete: ok, you've added the repository, you upgraded the chroot. ltsp-update-image is *required* after upgrading your chroot :)
08:28
<Comete>
alkisg: ok i do it now, test it and come back, thanks :)
08:28Comete has quit IRC
08:29
<alkisg>
Appiah: in /opt/ltsp/i386/usr/share/ltsp/ltsp-init-common, change the line:
08:29
NBD_PORT=${NBD_PORT:-"9572"}
08:29
to
08:29
NBD_PORT=9572
08:29Gadi has joined #ltsp
08:29
<alkisg>
Then run sudo ltsp-update-image. That should make swapping work again...
08:30
<Appiah>
ok I will get back with the result!
08:32
<alkisg>
Appiah: before doing the change, check if you have any /tmp/tmp.XXXXXX files of 32MB size, those would mean that swapping was working before.
08:32
(so that wasn't your problem)

alkisg, I got an error after running the ltsp-build-client command:

https://help.ubuntu.com/community/UbuntuLTSP/LTSPFatClients
08:34
* E: Malformed line 2 in source list /etc/apt/sources.list (URI parse)
08:34
is it anything to worry about?
08:35
The line seems to say "deb deb http://ppa.launchpad.net/stgraber/ppa/ubuntu karmic main"
08:35
<Appiah>
alkisg: ok , thanks
08:36
<fasaxc>
wonder if you don't need the deb in the EXTRA_MIRROR line in your .conf file?
08:36Comete has joined #ltsp
08:37
<Comete>
alkisg: well done ! :) no bug when rebooting now thanks !
08:37
oh and ldm is in french :)
08:37
i still this strange sound problem
08:38
<alkisg>
fasaxc: you're right, thanks, removing it...
08:38
<fasaxc>
I'm giving it another go without
08:38
<Comete>
i have sound sometimes when opening a session but not after
08:40
<fasaxc>
the build client command seems to run a lot quicker second time around, guess its caching packages now :-)
08:40
<alkisg>
fasaxc: yup, it's the MOUNT_PACKAGE_DIR="/var/cache/apt/archives" line ;)
08:40
<Comete>
if i open Totem to play a sound file, the speaker icon shows a red cross
08:45
<fasaxc>
alkisg, can I add extra EXTRA_MIRROR lines in ltsp-build-client.conf for e.g. medibuntu? If so, do I add a whole extra EXTA_MIRROR=... or just a new line inside the quotes?
08:46
<alkisg>
fasaxc: http://packages.medibuntu.org/ $DIST free non-free
08:46
(you can keep the $DIST as it is)
08:46
and /etc/ltsp/medibuntu.asc in apt-keys
08:46
fasaxc: but you can also install packages *after* the initial chroot installation, it's easier this way sometimes.
08:47
`http://dl.google.com/linux/deb/ stable main` for google chrome, etc etc.
08:47
fasaxc: feel free to add any info you think useful in that wiki page.
08:50
fasaxc: "a new line inside the quotes" <==

Sounds like pulseaudio's crashed on the thin client.
09:54
<Comete>
sbalneav: do you have an idea ?
09:55
pulseaudio is very bugy
09:57
<sbalneav>
Comete: yep, pulse has some problems. It seems a bit more stable on lucid.
09:58
I think it's very much tied into your sound hardware.
09:58
I tend to have thin clients that I know work "well" with LTSP, and I've had very little problem with pulse.
09:58
Other people with different sound hardware seem to have no end of difficulty.
09:59

fasaxc: ah, it's a 2 nic setup? OK, thanks for the feedback. Do you think that wiki page is enough to get someone going?
10:04
<Comete>
sbalneav: another problem is the new release of gcompris on http://ppa.launchpad.net/stgraber/ppa/ubuntu , it's too slow. Is it possible to reinstall the last one but keeping ltsp 5.2 ?
10:05evilx has joined #ltsp
10:06
<fasaxc>
It's definitely clear and easy to follow. It might be worth adding links to cover the obvious next steps like adding more apps to the chroot or setting up networking in a 2-nic setup
10:08
<alkisg>
OK, I'll put those to a link section on the bottom.

problem: my sound settings for all users are occasionally (in the middle of a login) just reverting ot whatever they were when they logged in.
11:29
so the headsets they were using keep going out, since the input and output is switching back to the internal audio, rather than the adapter
11:29
is there a way to patch this up?
11:41
<sbalneav>
anivair: sounds like a pulse problem. I'd combat it by setting up a hard-coded alsa config file.
11:41
.asound.conf I believe.

<anivair>
thanks, I'll look into it
11:56
second question: now that I have apps running locally, i cvan't see them
11:56
which is bad if I need to kill the process
11:56
<johnny>
of course you can't see them
11:56
what do you epect?
11:56
<anivair>
(ie, if I ps aux right now, I see no twinkle processes, even though everyone's ru nning it locally)
11:57
<johnny>
cuz they are running on that computer..
11:57
you would have to login to the clients to kill them
11:57
<anivair>
but I still need to be able to administer the accounts
11:57
<johnny>
administer the accounts?
11:57
<anivair>
because a moment ago, logging out of the session and back in didn't kill the process for them
11:58
<johnny>
of course not
11:58
oh wait..
11:58
i think that should
11:58
since ldm runs locally
11:58
i wonder if there's a way to tell
11:58
we do have ldm logout hooks
11:58
alkisg, so.. is there a way to make it so that when ldm is reset it kills the local processes? or should it do that already?
11:59
<anivair>
I thought it would, but unless it was a glitch of another sort, it did not
11:59
<johnny>
somebody here will knwo
11:59
<anivair>
I'm thinking about running them locally just for ease of administration, but I don't know if that would kill the function or no
12:00
I guess I can test it and see
12:00
<johnny>
ease of administration is running them on the server :)
12:00
but.. obviously many apps don't work well when you do that
12:00
<anivair>
well, I'm not sure how twinkle works under the hood, so I don't know if there is a real benefit to running it locally or not
12:01
<johnny>
if it a voice over ip app?
12:01
<anivair>
it is
12:01
sip phone
12:01
<johnny>
then locally is probaby better
12:01Lns has joined #ltsp

Hi, has anyone managed to get chrome to work as a local install (I'm using a fat client setup).... I find it crashes with "Operation not permitted" (I think when it tries to create its lock file)
12:31
<alincoln>
fasaxc: i and a pal of mine got the same thing. i was going to try it with SSH_FOLLOW_SYMLINKS = False when i next had a chance, so you might try that
12:31
<fasaxc>
alincoln, thanks, where do I put that flag
12:33
<Lns>
sbalneav, one comment says "still, there are inefficiencies: -Ltsp is over ssh. that means no udp. they also have to mantain a whole login manager. was openvpn that difficoult to use? ipsec? - X11 connection. 100mb/s connection is NOT enough for a 1280x1024 desktop. just try to see a youtube hd video." LOL
12:33
<alincoln>
fasaxc: have you done any lts.conf editing before?
12:35
<Lns>
In any case, it's great to see the publicity for LTSP on such a "mainstream" tech site as Slashdot
12:35
Hopefully it'll attract some more momentum for the project
12:37
<alkisg>
johnny: is that localapps? I've no idea, I guess any X apps are killed when X is restarted...
12:37
fasaxc: yeah, symlink problems can be worked around with SSH_FOLLOW_SYMLINKS=False in lts.conf
12:37
<fasaxc>
I'll give it a try
12:38
<johnny>
alkisg, he was saying that it wasn't ..
12:38
<alkisg>
fasaxc: that's also true for pulseaudio and googleearth
12:38
<sbalneav>
Lns: Yeah, lots and lots of "experts" on /.

do we have to add any special ppa's to get ltsp 5.2?
13:28
<johnny>
yes
13:28
what would you expect?
13:28
ltsp 5.2 won't appear in any release until lucid for ubuntu

johnny: ohh ok I thougth when I read it was backported that it would be the default....cool i'll add your ppa
13:29
<johnny>
it ain't my ppa
13:29
oh.. of it's backported..
13:29
you need to use a seperate repo
13:30
/me doesn't know what that is for ubuntu
13:30
i guess jaunty-backports ?
13:30
then i guess you do'nt need the ppa
13:30
does it say which release it was backported for thunsucker ?
13:30
<thunsucker>
i think it was karmic
13:30
sec checking
13:31
Packages for LTSP 5.2, LDM 2.1 and LTSPfs 0.6 are already in Ubuntu Lucid and a backport for Karmic is available.
13:32
a quick check and after an update and dist-upgrade, 5.1.90 is installed
13:32
I'll just add the ppa
13:35
<johnny>
you're not really gaining that much from upgrading tho probably

ltsp-cluster was an adaptation from what was once mille-xterm
16:19
code coming out of revolution linux
16:19
<frederickjh>
From what I have read it seems that it is best to almost start over in a sense.
16:19
<john_s>
Interesting. I am running a quad core with 16 Gig's of ram serving about 50 clients, and I running out of CPU
16:19mgariepy has quit IRC

a company who did large scale deployments
16:20
its not green - only not well documented or as easy to use as it will grow to be
16:20
<frederickjh>
With the ltsp-cluster you seperate the file server boot machine from the servers that serve up applications.
16:20
<john_s>
Thank you Gadi
16:20
<Gadi>
ltsp-cluster has several pieces to it
16:20
a control center, a load balancer, etc
16:21
whereas regular ltsp is controlled by an lts.conf grabbed over tftp on boot,
16:21
<frederickjh>
Another un-well-documented opensource project. What's new.
16:21
<john_s>
frederickjh: I assumed as much. My district was looking at Stoneware which I think does similar things, but I am trying to keep us on the Free path
16:21
<Gadi>
ltsp-cluster is controlled by a "wget" call to the ltsp-cluster control center that retrieves settings at various breakpoints in the client lifecycle
16:22etyack1 has quit IRC

<john_s>
Gadi: I read that much of this is being handled over HTTP. Do you know of any schools that have deployed this in the U.S. or Canada?
16:22
<frederickjh>
So, Gadi, do you know if you can use a current machine such an a Ubuntu Karmic and add a application server and make this work?
16:23
<Gadi>
john_s: rev linux has a 5000-client deployment up in Canada
16:23
I am in the midst of prepping a deployment that makes use of some ltsp-cluster in the US right now
16:23
<john_s>
I'll take a look at their website
16:23
Gadi where abouts are you located?
16:23
If you don't mind me asking
16:24
<Gadi>
personally, I am in NY, but the school I am doing this project for is out in CA
16:24
frederickjh: you can use individual machines
16:24

and just have separate app server VMs
16:25
no reason those couldn't be real machines

16:27
<Lns>
for sure, that would be cool.
16:27
just lemme know when
16:27
<frederickjh>
I am maxing out the CPU with myself running on the server and one other client at times depending on the apps being run.
16:27
<Lns>
I can come out to where you're at this time
16:27
frederickjh: what will you be using it for?
16:27
<frederickjh>
I am thinking of adding another p4 that I have laying around as a application server but am not sure if it will help.

frederickjh: ...well think about it. Would you use a loaded machine that you tax out for gaming all the time for 3 other people to use simultaneously?
16:28
It's not like LTSP creates cpu cycles and memory for you =)
16:29
<frederickjh>
Can you do that so that the ones that come on first go to one machine and the other go else where?
16:29

Hey Gang - I'm running LTSP 9.04. I think that iTalc uses port 5900, which is the same one used by VNC (vino). Is there a way to install iTalc on an ltsp server and still get to that server using VNC?
16:32
<Gadi>
mostly a howto with openvz
16:32
<john_s>
Gadi: I see a setup for OpenVZ which I am not familiar with
16:32
<Gadi>
I am using xenserver
16:32
not openvz
16:32
<Lns>
Mip5: woah! I thought we were only at 5.2!!! Where can you download LTSP 9.04? ;)
16:32
<Gadi>
bec, like u, I dont know openvz
16:33

lns - hah! lol

Gadi: Is virtualization the preffered approach
16:33
?
16:33ogra_cmpc has joined #ltsp
16:33
<Gadi>
john_s: it makes things easier - especially if you start worrying over failover and high availability
16:34
I have right now 2 xenservers and 6 VMs
16:34
3 each
16:34
that are for load balance and high availability
16:34
stgraber's team usually do more than that and split up everything
16:34
<john_s>
So is the clustering sits on top of several vms which may sit on several servers?
16:35
<Gadi>
well, lets not confuse things too much and assume that ltsp-cluster does more than we think
16:35
(thats what happens when people say cluster - they think it does everything and more)
16:36
the control center manages client configuration
16:36
<john_s>
Gadi: Do bandwidth requirements change in setups like yours e.g. server to server, server to client
16:37
<Gadi>
change? no
16:37
the only server-to-server bw I worry about is that the two xenservers connect to a NAS for the VMs
16:37
but thats on the backend
16:38
<john_s>
Gadi: So the VM's are read into memory from a NAS?
16:38
<Gadi>
client to server is still the same
16:38
no - they live on the NAS
16:38
but run on the xenserver
16:38
<john_s>
So you write changes back to the NAS?
16:38
<Gadi>
right
16:39
that way you can "live migrate" VMs across xenservers while running

<Gadi>
this roll out will be for 350 (but it is not yet in production - looking to start rolling out next month or so)

16:41
<john_s>
so 350 on two physical server + app servers?
16:42
Gadi: That's essentially our setup as well
16:42
<Gadi>
yeah, these are two physical servers
16:42
right now, quad xeons with 16GB RAM each

john_s: just an aside, what is new about ltsp-cluster is its integration (client side) into ltsp and therefore its farther reaching reach
16:49
john_s: I expect as more people start using it, you will see more hands working on it than just the rev linux guys
16:49
<john_s>
Gadi: What do you mean?
16:49
<Gadi>
well, ltsp-cluster used to be just "an internal rev linux project"
16:49
that rode on top of ltsp
16:50
<john_s>
vagrantc: do do anything with the FG folks in Portland these days?
16:50
<stgraber>
technically it was always open source ;)
16:50
<vagrantc>
john_s: yup. it's rocking!
16:50
<stgraber>
it was then called MilleXterm and available on some weird (but public) SVN branch
16:50
<Gadi>
over the past few years, we worked to get the client piece integrated into ltsp proper
16:50
(I should really say, stgraber worked)
16:50
:)
16:50
<stgraber>
now we cleaned everything, changed the name, rewrote a few part and published it as ltsp-cluster with a good integration in upstream LTSP
16:51
<Gadi>
ok - but fair to say, it was a project used almost exclusively by rev linux
16:51
<stgraber>
yep, until a few months ago we were the only ones to have it deployed
16:51
<Gadi>
so, now that it is more integrated upstream, I think there will be more hands on deck
16:52
<stgraber>
now we are starting to get calls from people who installed it themselves and either want help making it more reliable (HA, huge infrastructure, ...) or want some custom development on top of it
16:52
<johnny>
anybody here any good with openoffice calc macros?
16:52
or something..
16:52
<john_s>
stgraber: If I am looking to set this up and try it out, should I be working from the howto OpenVZ
16:52
<stgraber>
yup, also the rewrite we are working on at the moment should help getting more contributors as the code is a lot cleaner, properly commented and using well-known technologies
16:53
john_s: yep, the OpenVZ howto is probably the best to start with ltsp-cluster. If you don't like VZ, you can either install everything on the same box or consider each VZ container as one physical server or VM.

Is the VM a matter of preference or does OpenVZ offer more clustery goodness?

17:08

17:10
at LEAST take me on a tour. ;)

Lns: we mentioned a few deployments on ltsp-cluster.org but without any names or details ... though I know we give that kind of information, including contact information for a few of our existing customers to these who are really interested in working with us (as in Revolution Linux)
17:10

17:13
<john_s>

carbm1: well, fortunately we don't have that many of these, then we can either run them in WINE (for these that support it) and for the others, we worked on the seamless patch for rdesktop that lets you integrate Windows applications from a TS environment in your Linux desktop
17:29
carbm1: you can check the video at the bottom of https://www.ltsp-cluster.org/tour for an example
17:29
<john_s>
Mip5: I see here http://italc.sourceforge.net/wiki/index.php?title=ITALC_in_a_ThinClient_environment#Installation_and_Operation_of_iTALC_in_the_Ubuntu_LTSP_environment that iTalc has a variable
17:29
that binds the port "my $isdport = 5800"
17:29
perhaps you could change that?
17:29
<Mip5>
john_s: I saw that too, but I don't think that's the port that's the problem.
17:29
<john_s>
I can't find much documentation about vino
17:30
<Mip5>
vino-server runs on 5900, so I think it's the ima (italc master) that I have to change.
17:30
<Lns>
http://www.pcmag.com/article2/0,2817,2357618,00.asp - anyone use these w/ltsp yet? =) looks so cool!
17:30
<john_s>
Mip5: sorry I thought you said there were two process listining on that port
17:31
<Mip5>
I think both are using 5900 (iTalc master and vino-server) - that port the client uses appears to be 5800 - but I don't think that's the one that needs to be changed
17:31johnny has joined #ltsp

17:33

john_s: I'm not sure how to interpret the output

stgraber: how do you manage printing? E.g. Do you have a way of directing individual thin clients to printers closet to them? I have to use static IP's to make this work, but of course this doesn't scale?
17:45
<stgraber>
john_s: yes, in the ltsp-cluster control center, you can create groups (usually representing buildings and classrooms) and for each assign a set of printer to show as well as a default printer
17:46
john_s: if you are using a recent Ubuntu or Debian, we have patched CUPS in these two so it lets you filter what's shown to the user.
17:46
<john_s>
stgraber: cool. I assume groups are defined on the cluster and not pulled from AD?
17:48
stgraber: Is load balanced NX used to offer "desktops from home"
17:49
I wonder if this isn't a candidate for a live ISO, in the way that LTSP used to be offered via knoppix (first time I used LTSP was on a Knoppix live disk distro)
17:50
stgraber: in order to get ones feet wet
17:52
Also would you suggest following the howto with Karmic or using Jaunty (which I think is on the howto?)
17:58frederickjh has quit IRC
17:59
<stgraber>
john_s: right, groups are more like a tree node (it's showing your thin clients inside a tree structure)
17:59
john_s: load-balanced NX is indeed for desktop from home using the same backend as for regular LTSP thin clients during the day
18:00
john_s: Edubuntu 10.04 should have Live LTSP right from the DVD
18:00
sorry for the late replies, I was answering a ton of mails ;)
18:00
<john_s>
No prob. Does Live LTSP incorperate clustering?
18:02
<stgraber>
nope it won't though it's only a few apt-get away from getting a ltsp-cluster setup
18:02
I'd try to avoid installing apache, postgresql and other stuff like that on the livecd :)
18:02* vagrantc adds ltsp-cluster to vagrantc's TODO list for the 365th time

18:02

18:03
<stgraber>
vagrantc: a customer I'm currently working on at the moment used to run it on Lenny :) We reinstalled it on Hardy and Karmic as I like things being standard (as in Revolution Linux's standards) but it seems like it worked just fine.
18:04
vagrantc: for the backend stuff you just need php5, apache, postgresql > 8.1 and python >= 2.4 :) not exactly hard to find and our packages shouldn't contain anything ubuntu-specific
18:04
<vagrantc>
stgraber: yeah, it's just a matter of trying it

stgraber: sorry 1 more thing. A single 4 core 16 gig server handles approx how many thin clients?
18:15
stgraber: and are ALL applications pushed off to application servers e.g. you might have an OpenOffice server and a server that just hands out the desktop to the user
18:15
<Lns>
john_s: it really depends on what you're using the server (clients) for.
18:15
<john_s>
Lns: Well the way I use it now, is that all clients get a desktop and all apps server from a single beefy server.
18:16
<stgraber>
john_s: our demo setup is a Q6600 with 6GB of RAM and we run 40-60 thin clients out of that but that's with firefox running locally
18:16
<john_s>
but that isn't working as well as it might
18:16
<stgraber>
john_s: if firefox runs on the server, then it's probably half of that
18:16
<Lns>
stgraber: true thart
18:16
that*
18:16
firefox is a paaaaaiiin server side...localapps was made FOR firefox, no? ;)
18:16
<john_s>
stgraber: Ok. So you might only break of *some* heavily used apps to a different server
18:16
?
18:17
<stgraber>
john_s: usually we install everything on all servers as it's the easiest and haven't seen much interest in having "specialized" servers yet. Though with X11 it's perfectly possible to do that
18:17
<john_s>
stgraber: ok
18:17
<stgraber>
john_s: we never had to do it, currently video intensive applications are moved to localapp when possible
18:17
john_s: that solved most of our issues at the moment
18:17
<john_s>
I feel the firefox pain. However it's been argued that this is really FLASH pain
18:18
<stgraber>
right, it's usually flash that's causing the issue but you can't only move flash to localapps, you have to move firefox as well
18:18
<Lns>
john_s: it's been both in my experience, but flash is definitely worse imho
18:18
<stgraber>
(though it's not technically true, I know some managed to run only flash locally but it's really a huge hack ;))
18:18
<john_s>
stgraber: I guess the issue I might have with local apps is that I'll have to replace a number of older thin clients that probably won't have enough memory to run them well
18:18
<stgraber>
john_s: usually if you want to run firefox locally, you'll need at least 512MB of RAM
18:19
<Lns>
stgraber: isn't localapps selective in clients it serves to? I.E. you can have both to choose from?
18:19
<stgraber>
john_s: though with ltsp-cluster you have the concept of "hardware groups" so you can match all thin clients with more than 512MB of ram and turn on local firefox only for these
18:19
<Lns>
;)
18:19
<john_s>
stgraber: thanks. Yeah I have a large percentage of very old clients that probably won't make it under karmic
18:19
<stgraber>
Lns: I guess you meant that ? ^ ;)
18:19
<Lns>
yup!
18:20
isn't localapps itself selective by nature though, meaning you can tell it who to serve localapps to, and which ones?
18:20
<john_s>
stgrabber: I see that the revlinux site has a thin client on the back of an lcd, do you have a recommend TC for folks looking to upgrade?
18:21
<stgraber>
who as in "the thin client" yep, and which one, absolutely you have LTSP_LOCALAPPS_SOMETHING that's a comma separated list of localapps
18:22
<Lns>
yeah i remember looking over that
18:22
oh i'm so excited to load my new server with lucid =)
18:22
<stgraber>
john_s: anything that's Atom based will work great (as long as chipsets are Intel as well). Currently we have quite a few Asus EEEbox, EEEtop (all-in-one touchscreen) is great too. Other than that Symbio, HP and a few others have great Atom-based thin clients for very similar prices.
18:23
<john_s>
stgraber:Thanks for the tip. I haven't really messed with local apps too much, just enough to notice that older clients don't like it. One kink that I am a bit worried about with local apps is that our storage is mounted via nfs so I am not sure how local apps will access network based storage with proper credentials
18:23
<stgraber>
john_s: usually you can find a decent thin client for $200-250 (even some cheaper than that). Just avoid Geode and VIA as these used to be good but now are really not worth the few bucks you'll save ;)
18:24
john_s: the home directory is automatically mounted over sshfs from the application server for localapps. No need to setup NFS or anything like that on the thin client.
18:24
<john_s>
stgraber: I recently got a windpc TC for about 140 with 2 G ram and and atom processor. It works very well
18:24
<stgraber>
john_s: it's automatic and it's secure (as secure as SSH at least ;))
18:25
john_s: yep, that's probably one of the usual Atom 230 + Intel 945GM + Realtek network. That's the standard Atom platform and that works great.

stgraber: the local mount of the remote filesystem is per user and is part of Karmic/Lucid etc, am I right? That's cool. I need to find out more about this.

<stgraber>
at the office I currently have a touchscreen EEEtop 19" (or something like that) + a Symbio in a dual-head setup (VGA + DVI)

john_s: yep, when you login in ldm, your home directory gets automatically mounted at the same place as it's on the application server. That way localapps won't notice any change and will be able to use your config just fine.

So, I'm setting up ltsp, and I am able to boot to the log in screen, and log in with my username and password, but then I get a command line instead of Gnome. Any ideas? Do I need to install ubuntu-desktop in the thin client root?
22:11
<vagrantc>
should be installed on the server
22:13
<Ralth>
so I install ubuntu-desktop on the server as if I were going to use gnome directly on the server?
22:15
<sbalneav>
Ralth: Yes.
22:16
<Ralth>
Thanks!
22:20
<vagrantc>
all applications (typically) run on the server
