OK, from appnr then: http://appnr.com/install/epoptes
05:51
Cool, it works! :)
05:51
<Hyperbyte>
alkisg_web, it doesn't work! ;(
05:51
<alkisg_web>
Hyperbyte: why, if you click on the last one, it should open software-center to install epoptes...
05:51
<Hyperbyte>
alkisg_web, no. :(
05:52
<alkisg_web>
What client are you using?
05:52
(and default browser?)
05:53

05:53
Doesn't work. :(
05:53* Hyperbyte sobs and heads out to work where he has Ubuntu! :-D
05:53
<alkisg_web>
Hahaha I'll file a bug on Internet Explorer for it to support apt repositories :P :D
05:54
...hmmm maybe it would be better to tell appnr.com to redirect IE users to http://goodbye-microsoft.com/ :D

looks like ltsp_localapps_menu and .. _menu_items dont work. I have to run programs manually via ltsp-localapps and not via system menu. is this bug or havent implemented yet?
06:39
<alkisg>
You're not doing it correctly
06:43
<mealstrom>
lts.conf: http://pastebin.com/wB7tK0QR , applications are installed in chroot and image is updated
06:45
or i should add variable local_apps_whitelist with space-separated list of commands ?
07:02
<Hyperbyte>
mealstrom, hey, you're using sflphone with LTSP!
07:02
Me too!
07:06
<mealstrom>
Hyperbyte: :D yeap. im using it on fat 10.04 and thin 12.04 clients :D
07:06
<Hyperbyte>
mealstrom, awesome.
07:06
On 12.04, make sure you use the latest version
07:07
1.0.2 doesn't work properly on 12.04
07:07
<mealstrom>
Hyperbyte: but i have a problem to lunch as local apps. all audio programs just kills my system
07:07
<Hyperbyte>
mealstrom, I can definitely help you.
07:07
I have sflphone working on 12.04 as both local app and server app.
07:07
But, strange as it sounds, on 12.04 sflphone works better as server app for me. Could be my hardware, don't know.
07:08
<mealstrom>
Hyperbyte: im using 1.1.0 version
07:08
<Hyperbyte>
But the interface is very sluggish on 12.04 as a local app... as a server app it responds quickly. I've also had trouble with audio stuttering as a local app, and not as a server app.
07:08
I can't even begin to understand -why- a softphone would work better via remote X and networked pulse audio, than just locally on the client, but that's how it is for me.
07:09
So you might want to experiment.
07:09
Now onto the local apps menu - have you verified that sflphone-client-gnome works on the client as localapp?
07:10
<mealstrom>
Hyperbyte: if i run it as ltsp-localapps sflphone-client-gnome from console it starts as localapp and everyone is happy - no server's CPU usage, no lags. If i run it from Applications-Internet-sflphone -- it starts on server -- and this is horrible for CPU.
07:11
<Hyperbyte>
Interesting. :)
07:11
Horrible for CPU on the server, or on the client?
07:11
<mealstrom>
Hyperbyte: every program that starts on server and translates sound -- eats a lot of server (not client) cpu.
07:12
Hyperbyte: totem / vlc / skype / sflphone / pidgin
07:12
<Hyperbyte>
mealstrom, hmm.. haven't really noticed that.
07:12
This is on 12.04?
07:13
<mealstrom>
Hyperbyte: yes. server and clients are 12.04, but im using VBox for testing thin clients (3 cores / 4 Gb RAM), maybe this is the issue with sound, but otherway -- i want some programs to lunch locally.
07:14
Hyperbyte: and my localapps_menu doesnt work or i just have something wrong configured.
07:17
<Hyperbyte>
mealstrom, to be honest, I've never bothered with localapps menu
07:17
Always just created launchers in /usr/share/applications/ on the server
07:19
mealstrom, seems like sound applications on the server are using quite a bit of CPU here as well
07:20
I'm running on a 6-core 3.3ghz AMD Phenom processor though, with ~10 users, so I haven't really noticed it.
07:23
<mealstrom>
Hyperbyte: they are coding/decoding stream and sends raw data to client. client just plays, no cpu load. Im going to take yours advise with creating launchers.
07:26
Hyperbyte: im running 4-core/8GB amd phenom with ~6 users(fat) and virtualbox on it(3-core 90%cap 4GB) for ~3-4 thin clients test system . And VirtualBox eats a lot of CPU when working with audio
07:29
Hyperbyte: have you edited at /usr/share/applications Exec=COMMAND to Exec=ltsp-localapps COMMAND ?
07:33
Hyperbyte: ok, ive managed with that, just created local and server ones entries
07:38F-GT has joined IRC (F-GT!~phantom@ppp121-44-97-140.lns20.syd6.internode.on.net)
07:39
<Hyperbyte>
mealstrom, easy isn't it? :-)
07:39
Only disadvantage is that you can't set it on a per-client basis, like you do with LOCAL_APPS_MENU in lts.conf
07:39
<mealstrom>
Hyperbyte: yes, peace of cake :D
07:40
<Hyperbyte>
But I don't need that, so I've never bothered with the lts.conf variables for it.
07:40
<mealstrom>
Hyperbyte: my LOCAL_APPS_MENU doesnt work, so ive no choice .
07:40
<Hyperbyte>
mealstrom, oh, if you need it working I'm sure alkisg can tell you how.
07:41
Or some other LTSP developer... I've just never used it, so can't tell you what you're doing wrong. ;-)
07:41* alkisg is writing some wiki pages for greek schools now, will be available later on...
07:41
<mealstrom>
Hyperbyte: ive tryed to look up at scripts for variable LOCAL_MENU - but no luck.
07:41alexqwesa has joined IRC (alexqwesa!~alex@109.172.12.47)
07:41
<mealstrom>
alkisg: good luck .
07:42
<Hyperbyte>
mealstrom, it's called LOCAL_APPS_MENU isn't it?
07:43
Look at <chroot> /usr/share/ldm/rc.d/X02-genmenu
07:44
That's where the local apps menu is generated
07:44
Doesn't tell me much though.
07:44
I can tell you this:
07:45
The program 'sflphone' doesn't exist on your client. The executable is 'sflphone-client-gnome'
07:45
See if you can get it working with just one entry..
07:46
About your lts.conf
07:46
I don't think you need "LIKE = default"
07:46
[Default] gets applied to all clients anyways
07:47
And put LOCAL_APPS_MENU_ITEMS=sflphone-client-gnome
07:47
(just one item, to test)
07:50Phantomas has left IRC (Phantomas!~Phantomas@unaffiliated/phantomas)
07:52
<mealstrom>
hm... if boolean_is_true "${LOCAL_APPS:-True}" does this line is correct for function?
07:53
alkisg: can you look here for a moment ?
07:53
<alkisg>
Yes it's fine

mealstrom, I'm pretty sure the LTSP code is working
08:06
<mealstrom>
Hyperbyte: it create tmp dir
08:06
Hyperbyte: all files seems to be ok
08:08
<Hyperbyte>
mealstrom, there could be something in the home dir of the user you're logging in with that overrides the menu maybe?
08:08
Either way - do you -need- to be able to create different menus for different clients?
08:09
<mealstrom>
Hyperbyte: you know what? it works now with LOCAL_APPS_MENU_ITEMS=sflphone-client-gnome,sflphone,skype
08:09
<Hyperbyte>
mealstrom, this is exactly what you had before, wasn't it?
08:09
*isn't it
08:11
<mealstrom>
Hyperbyte: i've forgot to restart thin clients. and yesterday i,ve got it with full path "Full-paths are required for each command. No spaces in the names are allowed." (man) and they doesnt work.
08:11
Hyperbyte: like LOCAL_APPS_MENU_ITEMS=/usr/bin/sflphone,/usr/bin/skype
08:20
heh.. i found a bug
08:21
<Hyperbyte>
!upstream-bug
08:21
<ltsp`>
Hyperbyte: upstream-bug: https://bugs.launchpad.net/ltsp/+filebug
08:21
<Hyperbyte>
Then be sure to report it. :)
08:23
<mealstrom>
heh, its already documented :D
08:24* alkisg takes a break from the wiki... so, is there some actual ltsp bug involved?
08:26
<mealstrom>
alkisg: it was documented and fixed.
08:26
<alkisg>
Ah, you're using an older version? ok
08:27
<mealstrom>
alkisg: yeap, it was on 10.04, 12.04 doesnt have it.

<jimjimovich>
are these instructions working with Ubuntu 12.04?
11:45
https://help.ubuntu.com/community/UbuntuLTSP/FatClients
11:46
<alkisg>
...some of them, the page has been edited too many times and you need to be careful when following it
11:47
<jimjimovich>
I can't seem to get fat clients to boot
11:50Parker955_Away is now known as Parker955
11:52
<jimjimovich>
is it possible to get Unity 3D working on thin clients if the clients support(ed) compiz in 10.04?
11:52
<alkisg>
Not really
11:53
...so you want fat clients to get 3d in unity?!!!
11:53
<jimjimovich>
no. two different questions :)
11:54
Unity 2D is working really horribly on the thin clients I'm testing. You can't even maximize a window correctly.
11:54
<alkisg>
Yeah and 3d is even worse... I'm using gnome-fallback
11:54
<jimjimovich>
the changes in desktop environments really present us some problems for upgrading.
11:55
does compiz work in "classic mode"?
11:55
<alkisg>
Gnome fallback is kinda like 10.04
11:55
There's a gnome-classic which I think uses effects etc
11:56
<jimjimovich>
I was thinking if we had fat clients, it'd help with the desktop and with some other apps. but I'm not sure if it's worth it.
11:56Parker955 is now known as Parker955_Away
11:56
<alkisg>
Worth what?
11:57
It's not like it involves more maintainance..
11:58
<jimjimovich>
I'm not sure how great the performance will be on lower-end machines that were meant to be thin clients
11:58
like atom processors with 1GB RAM
11:58
<alkisg>
Like running ubuntu locally
11:58
<jimjimovich>
exactly
11:58
<alkisg>
I.e. you can almost watch flash youtube, and that's about it
11:58
*fullscreen
11:59
<jimjimovich>
I think that'd be a pretty big step backwards for most of our users/clients
12:00
it's kind of a bummer to not be able to offer them Unity
12:00
<dgeary2>
jimjimovich, big picture question is does it make sense for your environment?
12:00
<jimjimovich>
Unity?
12:01
<alkisg>
My daughter's atom laptop easily does unity 3d as a fat client
12:01
<dgeary2>
jimjimovich, no, fat client
12:01
sorry for the ambiguity
12:02
<jimjimovich>
I think the biggest problem for fat clients would be RAM. I know how horrible my notebook runs 12.04 with 2GB.
12:02
bumped it up to 4GB and it runs like a dream
12:02[GuS] has joined IRC ([GuS]!~MysT@unaffiliated/gus/x-663402)
12:02
<alkisg>
...really?!
12:03
I don't think RAM (when you have 1 gb) is a problem on ubuntu desktop machines...
12:03
Anyways, back to work..
12:03
<jimjimovich>
chrome and firefox are both serious ram hogs.
12:04
<dgeary2>
i agree with alkisg, that 1G RAM should be sufficient
12:04
<jimjimovich>
maybe it'd be worth it to upgrade the ram and go fat client
12:04
how does swap work with fat clients?
12:05
<dgeary2>
jimjimovich, tell firefox and chrome not to cache
12:05
<alkisg>
Same as thin
12:05
<dgeary2>
alkisg, does that mean either 1) not, or 2) nbd ?
12:05
<alkisg>
1) not, 2) nbd, 3) local swap...
12:06
Whichever
12:06
<dgeary2>
sorry, i assumed local swap was out of the question for a variety of reasons
12:07
<alkisg>
Some people reuse old desktops for ltsp clients, there's nothing wrong there about using local swap
12:07
<dgeary2>
unless the local system is hibernated
12:07
<alkisg>
....why would that matter?
12:08
Ah you mean local linux system, yeah that's not too common
12:08
(having linux both locally and over ltsp)
12:08
<jimjimovich>
anyone using desktop environments besides gnome or unity?
12:12
<dgeary2>
alkisg, yeah local swap would be no problem if the local system was not linux, or not hibernated
12:12
but would involve repartitioning the hard disks of some or all of the clients
12:12
<alkisg>
Sure, I've done it lots of times
12:14
<bieb>
alkisg: I am looking for a way to configure the unity launch bar, add and removing programs students dont need to see. I know Sabaton could do this in the past, I had heard Sabayon doesn't work with 12.04..
12:15
<alkisg>
bieb: please ask in the channel, not specific persons... although #ltsp isn't appropriate for that question, as it's not ltsp-specific, maybe you should be asking in #ubuntu instead
12:16
<bieb>
alkisg: wouldnt it be ltsp specific if I was adjusting the launchbar to add to the image?
12:16
<alkisg>
bieb: if you _knew_ how to adjust it but not how to put it in the image, then yeah. But you _don't_ need to put the adjustment in the image.
12:17
You're free to ask anything of course; I'm just saying that you may find more suitable channels.
12:17
<jimjimovich>
bieb: http://askubuntu.com/questions/65900/how-can-i-change-default-settings-for-new-users
12:17
<bieb>
alkisg: why doesnt the adjustment to the launcher get added to the image?
12:18
<alkisg>
Because it's inside the user session which runs on the server
12:19
<bieb>
ohh I was thinking that I had to update the image

<yopla>
is there a minimal working lts.conf?
13:36
<ogra_>
yes, remove it
13:36
<yopla>
as soon as I put one on tftp server, I get black screen
13:36
<ogra_>
cant go more minimal and ltsp will default to autodetection
13:37
lts.conf should only be used where autodetection bits dont work properly or to override defaults
13:37
<yopla>
it is to launch xinit script
13:37
<ogra_>
theoretically your setup should boot without one in place
13:37
<yopla>
without it works
13:38
<ogra_>
so you likely picked a wrong option or some such
13:39
<yopla>
something like SCREEN_O2=shell
13:39
<ogra_>
is that a capital O instead of a zero ?
13:39
<yopla>
no sorry,
13:39
0
13:39
<ogra_>
well, that should give you a console login on tty2

SCREEN_02=shell

yes, that should work fine and get you a logged in console on tty2
13:44
<yopla>
I get black screen
13:45
<ogra_>
did you try pressing ctrl+alt+f2 ?
13:45
might just be that you dont end up on the right tty after boot

nothing else than balck screen

is there any resources where people can share configurations of ltsp/success stories or something like this?

I have asked this in ubuntu also with no answer.. if anyone can point me in the right direction it would be appreciated.. need help with defining "JAVA_HOME" I have added it to the end of the "Path" line in /etc/environment (...:/use/games:JAVA_HOME=/usr/share/java") and also tried it as its own line in environment (JAVA_HOME="/usr/share/java" neither seem to work, the print payment program that needs java keeps telling me JAVA_HOME is not defined!
14:48
<Hyperbyte>
mealstrom, there will be soon. A team is working on a new website and wiki. :)
14:50
bieb, have you Google for the error "JAVA_HOME is not defined"
14:50
?
14:50
Because I get over 100.000 results... should be something interesting in there
14:52
<bieb>
Hyperbyte: yeah.. I followed http://magnus-k-karlsson.blogspot.se/2012/04/how-to-set-javahome-environment.html that was the reason I posted here.. I am still looking.. but thought Magnus had a good setup..

ho did'nt know

its great software but sadly wont be integrated in any distro until thats fixed
17:13
(unless your distro doesnt care about security or maintainability)
17:14
<yopla>
from server side ?
17:15

from both sides

19:59* alkisg waves to vagrantc... whenever you got some time for the ltsp packaging, if you could commit the "missing" changes (even if they're not the best solution they do at least allow building on launchpad), and the lts.conf example,... ...then I could build directly from your packaging tree ;)
19:59

the bot is really useful if you remember exactly what you're looking for :)
20:00

20:00

that wave contained an impressive amount of content!
20:00

20:01
vagrantc: so, what do you have in your TODO list until the next debian upload?
20:01
(ltsp upload)
20:02
...please don't say pxelinux menus :P
20:02
<vagrantc>
alkisg: i keep misplacing my TODO list
20:02
alkisg: i'd like to test the "ltsp-update-image --config /" again, see if it was just a fluke
20:03
<alkisg>
--cleanup... hmm let me test on debian/lxde btw
20:03
<vagrantc>
alkisg: and i'd like to fix the "debuild -b -tc" correctly.
20:03
alkisg: so ... ltsp-update-image / really should always be run with --cleanup ... maybe we should/could make a separate option for it?
20:04
<alkisg>
The --cleanup option is supposed to help with .vdi images or real client images too, the "/" is just another use for it
20:04
<vagrantc>
alkisg: yes, but the syntax is a little odd to remember.
20:04
alkisg: it seems like a use-case that could justify it's own commandline option.
20:07
<alkisg>
ltsp-update-image --ltsp-pnp :P
20:08* alkisg should note in the prerequisites wiki section though that / should all be in one partition, at least for now
20:10
<vagrantc>
alkisg: not supporting a separate /boot is frustrating
20:11bengoa has left IRC (bengoa!~bengoa@2001:1291:229:2:216:cbff:feab:6cc9, Quit: Leaving.)
20:11
<vagrantc>
alkisg: could it at least special-case boot to bind-mount it too?
20:11
<alkisg>
vagrantc: what about a separate /usr? Do people use that a lot? Or other dirs?
20:11
Sure it wouldn't be hard to special-case /boot or even a few more dirs
20:11
<vagrantc>
alkisg: i don't know how much people use other partitions
20:12
alkisg: or at least a way to define which partitions need to be mounted?
20:12
<alkisg>
But I wonder if /boot is really needed in the image... yeah that ^ is probably the most sensible thing to do for now, or maybe try to autodetect them
20:12
<vagrantc>
ltsp-update-image --cleanup /,/boot/,/usr ?
20:12
looks ugly.
20:13
alkisg: considering that /boot is where the kernels are, i think it's pretty important, no?
20:13
<alkisg>
EXTRA_MOUNTS=/boot,/usr etc in ltsp-update-image.conf?
20:13
<vagrantc>
alkisg: yeah ... something like that ... although it's kind of ugly ... the beauty of this whole idea is that "it just works" :)
20:13
<alkisg>
vagrantc: if ltsp-update-image is smart enough to tell ltsp-update-kernels to get them from the server /boot, I'm not sure they're needed
20:14
<vagrantc>
alkisg: but if you want to move that image to another server, you'll need to mmanually move the kernels too ... there is a certain simplicity that everything you need is actually shipped in the image file.
20:14
<alkisg>
But it sounds complex, specifying more dirs to bind-mount sounds much saner
20:15
<vagrantc>
alkisg: what's so ugly about mounting all the dirs into the rofs?
20:15
<alkisg>
No I meant the opposite
20:15
omitting kernels == ugly, mounting dirs == sane
20:15
<vagrantc>
ok.
20:15
alkisg: but why not mount those dirs automaticallly?
20:15
alkisg: and then a list of excluded dirs?
20:16
<alkisg>
Not with rbind though, we don't want /dev as I think it'll cause problems
20:16
Only "real" partitions under / should be mounted
20:16
<vagrantc>
so leave it as an excluded dir.
20:16
<alkisg>
We do want the dev nodes though
20:16
...or are they all generated on boot if they're missing?
20:17
<vagrantc>
it needs some rudimentary ones ... but they should be present on the underlying /
20:17
<alkisg>
OK I'll try to find a way to bind-mount only physical partitions
20:17
<vagrantc>
or do bind-mounts hide what's underneath mountpoints that aren't also bind-mounted?
20:18
<alkisg>
I lost you, re-reading that a couple of times... :P
20:18
<vagrantc>
it's confusing :)
20:18
<alkisg>
What I'm saying is that if we put /dev/* in ltsp-update-image.excludes, that will cause problems, right?
20:18
<vagrantc>
ok, so right now, you bind-mount / to tmpdir/rofs .... and does that have the appropriate /dev nodes?
20:19
alkisg: yes!
20:19
<alkisg>
Yes, but without the actual data
20:19
<vagrantc>
alkisg: so have a separate mount excludes.
20:19
<alkisg>
So e.g. /dev/sda3 there won't be copied in the image
20:19
What if there's an NFS mount in, say, /srv/something? Do we want that included by default?
20:19
<vagrantc>
iterate through /proc/mounts, mount all the filesystems that aren't excluded ... done ?
20:20
so have some criteria for exclusion
20:20
<alkisg>
Since ltsp-pnp targets more novice users, maybe we could only have an include list, and not an exclude one?
20:20
<vagrantc>
alkisg: i think an include list will require them to actually understand why it wasn't working
20:20
alkisg: whereas an exclude list could have some sane defaults.
20:22
alkisg: for /dev, it wouldn't be any different than how we don't manually mount /dev now.
20:22
<alkisg>
Sooo.... loop through /proc/mounts, omit everything that starts with /dev, /sys, /proc/, /run, and bind all the rest except the ones in the excludes list?
20:23
<vagrantc>
basicaaly, yeah?
20:23
<alkisg>
...and we'd need them sorted so that they're mounted in order. Hm. OK, sounds like a plan.
20:23
<vagrantc>
dunno how ugly that exclude list is going to get :)
20:24
but it wouldn't limit us to single-partition installs...
20:24
which would be nice :)
20:24
<alkisg>
Urm "/" is listed twice in my /proc/mounts
20:24
<vagrantc>
right, some sanity checking will be needed
20:25
<alkisg>
gvfs mounts should also probably be omitted...
20:25
<vagrantc>
maybe even tmpfs
20:27
i wonder about /home in general
20:29
<alkisg>
vagrantc: http://paste.debian.net/171995/
20:29
/home is omitted anyways from ltsp-update-image.excludes

vagrantc: what part? The whole --cleanup / concept? I'll start using it in a month in all schools here with 12.04, but I don't think it'll be backported. And I hope you'll put it in wheezy... :)
20:31
(backported == in ubuntu 12.04 backports or updates)
20:31
Dunno how stgraber feels about ltsp backports though

<hays>
is there a way to run ltsp in a non-dedicated way, e.g. on a server with other services and on a client with an OS installed such as windows?
23:57
<vagrantc>
LTSP is just a collection of services, so you if you can run those services on your server, you can run an LTSP server.
23:58
for the client-side stuff, if you're not running the LTSP booted OS, it's just not LTSP ...
23:58
you might connect to an LTSP service ... but there is no LTSP protocol.

hays: are you looking for some sort of remote desktop functionality?
23:59
<hays>
yeah, sorta. I mean quite literally a remote desktop would be just vnc
23:59
i think it would be nice to have my linux machine able to serve up a graphhical login/desktop to my other machines
