johnny, thanks i did that now i onlt get busybox prompt initramfs no GDM login
02:15
now how to update image of i386, default is updating amd64
02:15
<johnny>
you should just remove the amd64 stuff
02:15
you need to use --arch=i386 wherever it says something to you about amd64
02:16
<Asad2005>
ok thanks

Hi , I tried setting up a kiosk and since then all my clients are getting the kiosk image from nbd_server , I have since removed all traces of kiosk to try get my default install working and I cant seem to find where nbd_server is getting its info. Any one have any ideas ?
03:25
I know get this in my daemon.log
03:25
nbd_server[7950]: connect from 192.168.0.100, assigned file is /opt/ltsp-kiosk/images/i386.img

<dean_za_>
hi ogra , found that had 2 entries port 2000 for original and 2001 for kiosk , tried hashing out kiosk did nothing. howdo i restart inetd
04:17
which is default port ?
04:18
<ogra>
well 2000 is usually the original
04:18
and default
04:18shogunx has quit IRC
04:19
<ogra>
beyond that it indeed matters what the filename directive in your dhcpd.conf points to
04:19
<dean_za_>
hasnt changed from default install
04:20
<ogra>
well, change the pat for the 2001 entry in inetd.conf, restart inetd and it shpuld work
04:21
*path
04:21
<dean_za_>
how do I restart inetd ?
04:22
<ogra>
sudo /etc/init.d/openbsd-inetd restart
04:22
something like tha
04:22
t
04:23
<dean_za_>
thanks , been looking for /etc/init.d/inetd , did this change in hardy ?
04:23
<ogra>
no
04:24
we switched from netkit-inetd to openbsd-inetd two years ago when debian dropped netkit-inetd .... thats the only change since ltsp5 exists in ubuntu

hello, can someone help me set up LTSP4.2 for local applications? I'd like to play sound on local terminal, I have difficulties setting up NIS server (if that is even required), currently all sounds by any user play on the server
04:38
<ogra>
frin, there are not many people anymore who could help with the old 4.2 stuff, stick around for some hours, with luck you find someone
04:48ogra has quit IRC

but is NIS neccessary to run local applications?
04:57
<ogra>
NIS is a big security hole

hi, does anyone here have an AMD Geode GX2 based device running Hardy?
05:33
I have just filed bug 236019 because the geode x driver seems duff, wondered if others had this issue.
05:33
https://bugs.edge.launchpad.net/ubuntu/+source/xorg-server/+bug/236019
05:34
The specific hardware is a Viglen MPC-L, but I _believe_ it's similar/same as the Linutop2, but don't have one to confirm it
05:37
<ogra>
popey, hey hey
05:37
popey, wait for Q-Funk, he has fixed packages for testing ... they are supposed to go into hardy-updates and 8.04.1

06:28
*ogra
06:29
<ogra>
dean_za__, run sudo chroot /opt/ltsp/i386 passwd -u before re-rolling the image

(man passwd would have told you :) )

ogra: do i recall you telling me that the v1 classmate _has_ an ATA interface inside? is this presented as an IDE connector insternally?
07:07
<ogra>
the v1.5, yes
07:08
v1 is what you have at home
07:08
<popey>
ah
07:08
bummer :)
07:08
<ogra>
rich is just getting new ones :)
07:08
<popey>
woudl they be faster booting off an sd card than the internal flash?
07:08
<ogra>
took me a month to make suspend/resume work on the crappy USB thing ... now they just drop it :/
07:08
<popey>
:(
07:09
<ogra>
not really
07:09
<popey>
i guess the cpu limits either device?
07:09
<ogra>
i bot mine off an SDHC card as fasst as from the internal flash or a USB key ... there is not much noticeable differentce ... they are all up after about 70secs
07:09
s/bot/boot/
07:10
<popey>
right
07:10
<ogra>
the missing L2 cache is the prob here
07:10
the atom powered devices will solve that though (ETA end of the year)
07:11
<popey>
atom classmates?
07:11
<ogra>
.oO( all these poor x-rayed children )
07:11
yeah
07:11
classmate 2.0 will use atom
07:11
<popey>
:)
07:12
<ogra>
and a proper resolution :)
07:13
<popey>
yeah, that's one reason I like the 9" eee, 1024x600 is just about ok
07:14
<ogra>
yeah
07:14
i'll likely move over to the mobile team soon to care for all these devices
07:15
3 years of edu are really enough :)
07:15
<popey>
i can imagine!

ogra: As per https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/235772 Martin says update from -proposed. I don't see an updated ltsp package in -proposed ... should I just want for some propagation or ...?
07:23
<ogra>
Blinny, that was accepted about 1h ago ... give it some hours to build :)
07:23
Betreff: Accepted: ltsp 5.0.40~bzr20080212-0ubuntu7 (source)

Okay - I've never opened -proposed .. not sure how this works. Thanks!

What can I say.. I'm just too quick!
07:24
*whoosh*
07:25
<Q-FUNK>
ogra: are you at LT already?
07:25
<ogra>
propsed: i (the dev) uploads something ... the release team inspects every line of the patch, then accepts it to -proposed, the buildd builds the package and drops the binary to -proposed .... there it sits for a week nd if it gets two positive feedbacks on the bug during that it moves over to hardy-updates
07:26
<Blinny>
Dig. Cool. Thanks.
07:26
<ogra>
Q-FUNK, nope, will drive tonight or tomorrow morning to much personal stuff here at home that kept me from going earlier
07:26
Q-FUNK, meet popey ... he has geode GX issues :)
07:27
Q-FUNK, https://bugs.edge.launchpad.net/ubuntu/+source/xorg-server/+bug/236019
07:29
Q-FUNK, are you in berlin already ?

yup

07:40slidesinger has joined #ltsp
07:40
<ogra>
well, he answered on 219630
07:41
sounds like you should try with the ncs driver instead of geode
07:41
*nsc
07:41
i dont think the pci id's do anything beyond getting autodetection to work, if nsc still supports that chipset it might work
07:42
<popey>
well there's two errors, the autodetection is one thing, and the driver itself seems broken
07:43
<ogra>
right, but martin said that gedoe doesnt support that chip at all ... nsc does thogh
07:44
<popey>
:(
07:44
<ogra>
at least thats what i read out of his coment
07:44
<popey>
yeah, so it seems
07:44
<ogra>
so try using nsc
07:44
<popey>
booting now :)
07:44
<ogra>
geode and friends are a major pain since gutsy
07:44
and the OLPC folks adding half breeded patches to it didnt help wither
07:45
*either
07:48
<popey>
just updating classmate using hardy image
07:48
<ogra>
yay
07:49
fi you plug in an additional usb key before booting the instaler you can actually install to the external key if you want ... should work on the eee as well
07:49
<popey>
can you install to an sd card?
07:49
I have an 8G SDHC one spare
07:50
well.. "spare" :)
07:50
<ogra>
no, but thats two or three lines ofr code to enabe it
07:50
i dont think its detected during boot
07:50
the installer would offer it to you after the lang selector
07:50
<popey>
the installer sees /dev/sdc as the internal flash disk yes?
07:51
<ogra>
no idea, i never look at device names, whats the real name of the device ?
07:51
<popey>
well it says it's formatting, and the usb stick is the only other thing, and the hdd light is flashing, so it must be that :)
07:51
<ogra>
should have something like MPD or MPD in t
07:51
*MPT
07:52
ah, right, if there is only one possible target i dont bother the user with a selection ;)
07:57Egyptian[Home] has quit IRC

<popey>
that worked nicely, thanks ogra
08:00
<ogra>
which one now ? classmate install or ncs driver ?
08:00
*nsc
08:00
<popey>
classmate
08:00
<ogra>
ah :)
08:01
welcome :) if you find probs, please report ... its still not the final image
08:03
(i'll roll final with 8.04.1)
08:04
<popey>
I'd like to see a simlar image for the eee - one that has the specific fudges for that hardware
08:04alkisg has quit IRC
08:04
<popey>
ooo, i thought you said you wouldn't be able to do the screen stretching thing any more?
08:04
<ogra>
thats what i will be working on in the future ;)
08:04
<popey>
nice
08:04
<ogra>
intel offers a special driver that supports panning as well as screen compression
08:04
that will be packaged for intrpid
08:04
*intrepid
08:04Can0beans has quit IRC
08:04
<ogra>
i'm not a friend of panning modes but as long as intel demands it it will stay in
08:04
<popey>
i note you're still using the i810 driver and not the intel modesetting one..
08:04
<ogra>
right
08:05
i810 uses xrandr differently
08:05
newer drivers drop panning support in favor of having a big virtul screen over multiple displays
08:05
<popey>
ahh
08:05
<ogra>
you can only have one or the other
08:05
that forces me to i810
08:06
<popey>
this seems a lot faster than the previous install
08:06
<ogra>
but i810 will die and i wont have any standard X way of doing panning
08:06
well, some months of work ;)

dpkg-reconfigure xserver-xorg.. just after the "emulate 3 button mouse" question, it falls over trying to load /lib/modules/foo/kernel/drivers/acpi/battery.ko "no such device" - well duh! it's a desktop
08:17
how silly
08:23
<Blinny>
hey hey! I've got a diskless workstation 1225 that I can consistently crash (full lock, no VTs), even with 128mb of NBD_SWAP enabled. How should I go about troubleshooting this?
08:23
And, actually, the DevonIT box I have does the same crash. This one is reproduced using F-SPOT
08:26
<alkisg>
ogra, I think I've just solved a bug, https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/173067 - is my posting there enough for the maintainter of the script to see it or should I do something more?
08:27
(we newbies need a who-is-who and what-is-what for the distros, maintainers, bug reporting etc... :))
08:27
<ogra>
alkisg, ltsp in ubuntu is minly me
08:27
*mainly
08:27Nuba1 has joined #ltsp
08:28
<alkisg>
yeap, but I don't know which script is Ubuntu-specific, which is debian... :)
08:28
e.g. I've seen vagrantc's name on some of them...
08:29
<ogra>
doesnt matter
08:29
if you find the bug in ubuntu file it in ubuntus bugtracker
08:29
we work together upstream, but every distro has its special tweaks
08:30
<alkisg>
even if it is dhcp-server crashing? I mean, a binary and not a script?
08:30
<Nuba1>
ogra... I've more or less made the ltsp-build-client plugin for low fat clients with nfs and ldap support...
08:30
<ogra>
well, that would be clearly ubuntu :)
08:30
<Nuba1>
should I call it workstation as it was called
08:30
<alkisg>
:) ok then! thanks!
08:30
<Nuba1>
or lowfat
08:30
?
08:30
<ogra>
Nuba1, then lets get it into th eextra-plugins in ubuntu :)
08:30
so we get testing from intrepid users
08:31
<Nuba1>
ok... let me put the finishing touches on it, ie, name etc
08:31
:-)
08:31
<ogra>
well, i havent even done anything for intrepid ltsp yet anyway
08:31
to much other work to do, so no rush
08:31
<Nuba1>
ok... so either --workstation or --low_fatclient will work?
08:32
<ogra>
why low ?
08:32
<Nuba1>
well, I just think of fat client being non ltsp
08:32
but could call it fatclient too
08:32
<ogra>
well, for me a fat client is a client runing ubuntu-desktop locally
08:33
if thats what yours does, lets just call it --fatclient
08:33
<Nuba1>
yeah, k...
08:33
<laga>
maybe with arguments for ubuntu/kubuntu etc?
08:33
<ogra>
since you will specify this option in ltsp-build-client i assume our users being clever enough to find out they do it in ltsp ;)
08:33
<Nuba1>
yeah those are in there
08:33
kubuntu/ubuntu/xubuntu
08:34
<ogra>
laga, i'll allocate some ltsp time in june, lets see that we get the mythbuntu stuff shaken out and merged upstream then ....
08:34
<laga>
ogra: right.
08:35
<Nuba1>
laga, I used the one question, I did auth-client-config in finalization... but maybe that should come before... what do you think?
08:35
<laga>
there was a bug report about the alternate DHCP ports in here, i'll try to get a patch ASAP
08:35
Nuba1: auth-client-config? never used that ;)
08:35
<ogra>
and we should also look if there is something we could split out into a more common plugin i guess debian would love to have a diskless media player as well ;)
08:35elisboa has joined #ltsp
08:36
<Nuba1>
that meant to say, I used mythtv's finalization part with cat <<EOF>> to put in some ldap config files
08:36
but after that it requires executing the above mentioned command
08:36
just wondering if I did it the right place
08:37
well, I'll paste it when I've finished testing it here
08:37
<laga>
ogra: i'm still not sure if the whole overlay thing with aufs is such a great idea.. an LDAP server would be nice ;)
08:37
<Nuba1>
problem is LDAP server is seriously broken in hardy...
08:37
<ogra>
no ldap in defaults .... i wont add any ldap dependencies to the packages :)
08:38slappy has joined #ltsp
08:38
<ogra>
we worked hard in the past to avoid any ldap involvement in all out ltsp implementations
08:38
(thats essentially why there still is no upstream fat client)
08:38
s/out/our/
08:38cyberorg has quit IRC
08:39
<ogra>
and why localapps isnt there yet ...
08:39
<Nuba1>
yeah, I thought about making a hakish option to copy passwd/shadow/group to the fat client environment
08:39
but it doesnt work as expected
08:39
<ogra>
whats hackish about that ... if its done right :)
08:39
<laga>
Nuba1: well, the mythbuntu plugin does that for one user
08:39
<Nuba1>
only ldap works properly
08:39
well, its not dynamic for one
08:40
<laga>
yes.
08:40
a shame :(
08:40
<ogra>
it could be :)
08:40
its only software
08:40
<Nuba1>
yeah, then might as well use ldap ;-)
08:40
<ogra>
and i heard we are deveopers :) the guys who change software to do the right thing ;)
08:41
<Nuba1>
oh... one thing that would be really nice, and I can't figure it out... how about mounting /home via sshfs?
08:41
<laga>
well, suggestions? ;)
08:41
<ogra>
laga, some ideas, yes
08:41
<Nuba1>
instead of nfs
08:41
<ogra>
doesnt wrk without hacking around a missing sshfs feature
08:42
the localapp spec has an explanation
08:42
<laga>
:(
08:43
<Nuba1>
:-(
08:43
<ogra>
sshfs has no statfs() call
08:43
firefox doesnt like that
08:43
nautilus neither
08:44
not sure about oo.o but i would be suprised if it was happy
08:44
but that should be fixed with the localapps implementation
08:45
<laga>
well, we probably want a real file system, not something which is missing important stuff ;)
08:45
<ogra>
well, its really only that call
08:45
you can wrap something in fuse around that ....
08:45
scotty had some proof of concept code i think
08:45
but never published it
08:46
<Nuba1>
shame
08:46
<ogra>
with that in place we can even make ldm automount /home on login ... just attached to the existing ssh tunnel
08:47
<laga>
i believe i saw a patch to add stats()
08:47
<slappy>
is there a way to change ldm appearance and language ?
08:48
<ogra>
slappy, lang depends on your distro theme works everywhere
08:49
<Nuba1>
buntu makes it easy though :-)
08:49
<ogra>
just look at /usr/share/ldm/themes
08:49
<slappy>
It looks like there is a default theme for clients, and I don't know how to change them on the server.
08:49
<ogra>
(in the chroot)
08:50
oh, and if you are using a newer version LDM_THEME in lts.conf should be supported
08:50
<Blinny>
Any ideas about where to start with my full-stop lock-ups?
08:51
<slappy>
I'll be back...
08:58
<Nuba1>
I could take out user creation out of the fatclient script entirely, as ldap does it, or I could but another switch in, so users can choose ldap or server-users

Gadi: rebooting file server seems to have licked the time wait issue..thanks..
09:06
<slappy>
ogra: I'm using ltsp 5 so I'll take a look at /var/lib/tftpboot/ltsp/i386/lts.conf.
09:06
is there a tag for language, like LDM_LANG or something like that?
09:06
cause all my uses are using french
09:07
<Nuba1>
dont think ldm language localisation has been done yet
09:07mccann has joined #ltsp
09:07
<Nuba1>
you could always start thought :-)
09:07
<slappy>
I would like to get involved, but I don't know where to start...
09:08
<ogra>
Nuba1, it has been done, but to late for inclusion in hardy
09:08
it only hi the upstream code two weeks before release and was no small patch
09:08
s/hi/hit/
09:09
the debian sid package has a bunch of translations already and the intrepid package i'll upload next week will too
09:10
<Nuba1>
oh cool
09:11
<ogra>
and since we have ldm in a separate package now i might even ask for a backport
09:13
<Nuba1>
I'm looking to buy a new laptop... on which I will install Ubuntu... any recommendations? I've looked at the dells, which seem nice, but I'd like a 17 inch screen
09:13* ogra just bought a http://www.notebook-paradies.com/oxid.php/sid/1d50de6550db2627431586ac1f13b370/cl/details/cnid/34d47e3d0619f1822.57725514/anid/34d47e3d1da300ea6.34265928/<b>NEXOC-Osiris-S621---Tablet<_b>/
09:14
<ogra>
not sure they make them with non german keyboards though
09:14
but apart from tablet calibration being painful, all HW worked right out of the box for me with hardy
09:14
<slappy>
ogra: just to be sure, /opt/ltsp/i386 is only there to create the image for client?
09:15
<ogra>
slappy, right
09:15
the squashfs in /opt/ltsp/images gets created from it if you run ltsp-update-image
09:16
<Nuba1>
damn nice price for a tablet pc
09:16
<ogra>
i got it with the fast HDD and 3G ....
09:16
<slappy>
so if I want a specific theme, the procedure is: chroot to /opt/ltsp/i386 ; apt-get install theme; add LDM_THEME=/usr/share/ldm/theme, right?
09:16
<ogra>
its faster than any of my servers in my basement :)
09:17
slappy, all available themes are installed with the ldm package, you would need to make your own
09:17
and LDM_THEME should only take the theme name iirc
09:17
LDM_THEME=edubuntu
09:17
<slappy>
I wanted the ubuntu-studio theme :(
09:18
<ogra>
i doubt anyone from ubuntsudio has ported anything to ldm
09:18
<slappy>
oh, i see. it's gdm
09:18
<ogra>
but if you make up a theme from ubuntustudio's images i'll happily include it in intrepid :)
09:18
<Nuba1>
and do u use the tablet part of it ogra?
09:19
<ogra>
ldm actually only knows two images ... the wallpaper and the logo floating on top
09:19
<laga>
ogra: the c't said that the resolution of the touch-screen wasn't that good in that tablet pc. can you confirm?
09:19
<ogra>
Nuba1, from time to time, yes ... its great to sit outside in my garden in the morning and read online news while slurping coffee
09:20
laga, the initial one was 1cmx1cm ... with recalibration its smooth
09:20vagrantc has joined #ltsp
09:20* ogra waves to vagrantc
09:20* vagrantc waves back
09:20
<slappy>
what a nice idea. I'll be back ( have to tack a coffee). Nice publicity ogra :)
09:20
<ogra>
laga, i can write in the screen and draw just fine ...
09:21
s/in/on/
09:21
<vagrantc>
ogra: you still able to make it for the hackfest? i heard ubuntulive was cancelled
09:21
<ogra>
vagrantc, yup, that got me the final approval actualy :)
09:21
<vagrantc>
i see :)
09:22
<ogra>
oh, you were half approved .... indeed then we cant cancel your activities ... just go ahead :)
09:22
need to book the flight though
09:22
wil be a busy month for me
09:22
first week asia ... third week london ... and from london to portland without going home
09:22
mind you, my clothes might stink :P
09:23
<vagrantc>
can't imagine you'd stink worse than me :)
09:23
<ogra>
haha
09:23
<vagrantc>
well, you do smoke...
09:23
<ogra>
we can compete
09:23
which covers the other ;)
09:26
<Nuba1>
and 12 inches isnt too small?
09:26
for the screen :-)
09:26
<slappy>
ogra: you said that theme's language depends on distro. Mine is in english. How can I change ldm theme for the client to be in french?
09:27
<vagrantc>
ogra: i went ahead and committed the unionfs -> aufs patches to ltsp-trunk
09:30
ogra: what sort of time-frame before you consider sync'ing ltsp with debian?
09:32
<Gadi>
is ubuntu moving to aufs?
09:32
<vagrantc>
Gadi: so i hears
09:32
<Gadi>
interesting
09:32
they are drop in replacements of each other, yeah?
09:32
<laga>
kinda.
09:32
<vagrantc>
for the most part
09:32
<laga>
aufs has some compatibility options, but i'm not sure if they're enabled
09:33
<vagrantc>
the patch was basically sed -e 's,unionfs,aufs,g'
09:33
<Gadi>
vagrantc: ah, good
09:33
<vagrantc>
well, at least debian's aufs has them enabled... ubuntu might do things differently.
09:33
<laga>
vagrantc: since the maintainer is the same guy, i doubt it
09:34
<Gadi>
do you know if casper moved to aufs?
09:34
<vagrantc>
good good
09:34
<laga>
Gadi: casper _can_ use aufs, there's a boot option
09:34
<Gadi>
that must be new
09:34
<laga>
yeah, it's new.
09:35
<vagrantc>
Gadi: i heard from ogra that the livecd's will move to aufs, so ltsp (at least for ubuntu) should also
09:35
<laga>
it didnt make sense before because there was no aufs :)
09:35
<Gadi>
well, aufs was on the fringe for some time
09:35
and then became the rage
09:35
:)
09:35* vagrantc rages with aufs
09:36alkisg has quit IRC
09:36
<vagrantc>
all i know is that simple patch made the NBD+squashfs+aufs work in debian where unionfs has only infrequently worked. makes me happy.
09:36
<slappy>
Is there a file to change ldm language. I looked at greeter-gtkrc but it's not the good one. There is surely a ressource file somewhere?
09:36
<vagrantc>
slappy: what linux distro and release?
09:37
<slappy>
ubuntu 8.04
09:37
<vagrantc>
i don't think that version of LDM supports translations...
09:38
<Nuba1>
as ogra said, it didnt quite make it into hardy
09:38
maybe there will be a backport soon... for now translations of ldm are no go
09:38
<slappy>
But if there is a ressource file I can change it to my needs. I don't need to have language specific to user
09:38
They all speak the same language
09:38
<vagrantc>
slappy: you would have to recompile ldm.
09:38
<ogra>
vagrantc, i'm still not sure if i will, sync or just grab bzr
09:39
june is my month for such stuff
09:39
<slappy>
oh, it's hard coded
09:39
<Nuba1>
ldm is C
09:39
<vagrantc>
ogra: cool.
09:39
<slappy>
I know C
09:39
<ogra>
i wont travel or be distracted otherwise this month
09:39
<slappy>
Where do I start.
09:39
<vagrantc>
ogra: well, if you push your packaging branches i'll work on merging them :)
09:40
<slappy>
Where are the source files
09:40
<vagrantc>
slappy: most likely grabbing ldm from trunk:
09:40
!ltspsource
09:40
<ltspbot`>
vagrantc: "ltspsource" is https://code.launchpad.net/~ltsp-upstream
09:40
<ogra>
or grab reh debian sid package and mangle the versioning
09:40
then just build it
09:40
it should have french
09:40
s/reh/the/
09:41
<slappy>
ok thanks
09:41
<ogra>
oh, and note that the debian package doesnt ship themes
09:42captain_1agnus has quit IRC
09:42captain_magnus has joined #ltsp
09:42
<vagrantc>
doesn't ship ubuntu themes
09:42
it ships the ltsp theme :)
09:43
<ogra>
it ships one theme, right :)
09:43
sorry, thought that was obvious :)
09:43
<vagrantc>
i should get around to packaging an ldm theme for debian and freegeek
09:43
<ogra>
yeah
09:44
<vagrantc>
but i'll package themes in a separate source package
09:44
<ogra>
we should get people doing a theme contest and package the results in an extra-themes package
09:45
<vagrantc>
that'd be cool.
09:45
i need to get an upload in this month if it's going to make it into lenny
09:45
(this month, as in june)
09:45
<ogra>
i just did my last hardy upload last night
09:46
<vagrantc>
ogra: still working on that old thing? :)
09:46
<ogra>
its not done yet :)
09:47
<johnny>
beep
09:47
<ogra>
8.04.1 was the target :)
09:47
<johnny>
mmm... coffee
09:47alekibango has joined #ltsp
09:48
<vagrantc>
ogra: since we're diverging so heavily on ltsp-client-builder ... i'm still tempted to split it into a separate source package
09:49
what kind of compression are folks getting with squashfs and ltsp chroots?
09:49
<ogra>
zlib iirc
09:50
lzma isnt in the kernel, so the module cant make use of it
09:50
<laga>
lzma would also be possible with additional kernel poatches AFAIK
09:50
heh
09:50
<vagrantc>
the chroot i've built with was around 540MB... and the squashfs image around 400-some MB
09:50
<ogra>
ans lzma is a heavy beast, it eats RAM
09:50
<laga>
vagrantc: whagt chroot did you build?
09:50
<ogra>
though compcache uses lza
09:50
<vagrantc>
laga: just a regular debian sid ltsp chroot
09:50
<laga>
my mythbuntu-diskless image is 418M, and it contains everything.
09:51
the ubuntu chroot was like 140M compressed AFAIK
09:51
<ogra>
and we'll have compcache and the compression modules in intrepid with the next linux-ubuntu-modules
09:51
so i might be able to play with lzma here
09:51
vagrantc, did you have debs left in /var/cache/apt ?
09:51
<vagrantc>
i'm just trying to figure out if squashfs is .... not exactly broken on debian sid ... but maybe not working optimally?
09:52
ogra: nope.
09:52
<ogra>
they dont get much compression
09:52
<Gadi>
compcache is a compressed ramdisk as swap space, right?
09:52
<ogra>
my classmate root is 3.5G, compressed its 780M
09:52
<Gadi>
or is it for all free ram?
09:52
<ogra>
it really depends on the data you compress
09:52
Gadi, its the best since sliced bread
09:53
<Gadi>
lol
09:53
<ogra>
just doesnt taste as good
09:53
<Gadi>
does it make all available ram compressed?
09:53
<ogra>
it creates a /dev/ramzdsk device which is a compressed tmpfs
09:53
<Gadi>
or just swap?
09:53
<ogra>
you can surely also abuse it as normal fs
09:54
<Gadi>
ah - so we will abuse it by using it as the writable tmpfs overlay?
09:54
<ogra>
like any other tmpfs it only grabs a part of the ram
09:54
no
09:54
i will use it as virtual local swap :)
09:54
but indeed patches accepted
09:55
we dont really have much data we need writable, the need here for a compression isnt that big imho
09:55
<Gadi>
ah - so it is formatted as swap?
09:55
<ogra>
right
09:55
the default setup makes it swapspace
09:55slapp1 has joined #ltsp
09:55
<Gadi>
but you can format it any which way because it is a block dev from the kernel's pov
09:55
<ogra>
but i'm sure you can tweak it to do other useful things
09:55
<Gadi>
not a fs
09:55
<ogra>
right
09:56
<Gadi>
neat
09:56
<ogra>
i havent tried that yet, just fiddling with the normal usage and proper udev integration
09:56
<Gadi>
i guess the question is what percentage of free ram to make swap
09:56slappy has quit IRC
09:56
<Gadi>
:)
09:56
<ogra>
but once thats done i'll look at other opportunities
09:56
<Gadi>
and does this actually make the swap space faster than the regular ram?
09:56
<vagrantc>
does it eat a dedicated slice of ram, or just what it actually uses?
09:57
<ogra>
i need to make sure there are no issues with suspend/resume first
09:57
vagrantc, you can specify its size
09:57
<vagrantc>
yes, but if i specify 10M, and it only uses 2M ... will it consume 10M ?
09:57
<ogra>
(my main usecase are classmate and netbook for it, ltsp ram reduction is just an additional benefit for me)
09:58
vagrantc, i *think* it will only take 2 but cant confirm atm
09:58
does that matter though ?
09:58
<vagrantc>
ok.
09:58
<ogra>
i mean the main target it has s to increase the seen ram
09:58slapp1 has quit IRC
09:59
<ogra>
s/seen/usable/
09:59
<vagrantc>
when you're cutting it close, i suspect it matters a lot.
09:59
but anyways, time will tell :)
09:59
<ogra>
right
09:59
i'll work a lot with it the next months
10:00
ask me in august and i can hold a talk about it :)
10:00
<vagrantc>
ogra: is it packaged for ubuntu and/or debian yet?
10:00Pascal_1 has quit IRC
10:00
<ogra>
it is in linux-ubuntu-modules
10:00
in intrepid
10:00
debian doesnt have it yet afaik
10:00
<vagrantc>
it's just a kernel module, no kernel patches required?
10:01
<ogra>
http://gitweb.heh.fi/?p=ion/ubuntu/compcache.git
10:01
just grab that git source
10:01
<vagrantc>
that presumes i'm literate :)
10:01
<ogra>
run mak and you should be able to use the scripts
10:01
*make

what does everyone do for asset management?
10:06
we want to put a barcode on everything, scan it in, input the serial number + model + make, etc, and be able to destroy stored assets if we retire equipment, sell it, etc
10:08
<Nuba1>
I use schooltool or ClaSS for that
10:08
well for that and grade reports, assesments, attendance, etc
10:09
schooltool still needs some work, but after years of stagnation, the project seems to be moving along again
10:10
but neither of those solutions allow for something fancy like barcode scanning

10:23
<Nuba1>
what could cause the portmap deamon to take 5 minutes to start up
10:25
<ogra>
missing looback interface
10:25
broken resolver
10:26
<Nuba1>
network manager interfering
10:26
<shogunx>
thanx Blinny.
10:27
<ogra>
Nuba1, NM wont touch static devices
10:29
<johnny>
not yet at least :)
10:29
.7 is lookin good now tho
10:30
<ogra>
yeah, i used it for some weeks during hardy
10:30
but we revrted
10:31
<johnny>
still too early.. but it's gettn there
10:32
<Nuba1>
well, the script I based my fatclient on, purges networkmanager... but I'm unsure where /etc/network/interfaces is setup
10:32
in ltsp-setup-client?
10:33
<ogra>
ltsp-build-client sets up loopback iirc
10:33
and beyond that this file isnt touched
10:33staffencasa has joined #ltsp
10:34
<Nuba1>
hmmmm... then perhaps my ltsp-build-client isnt finishing
10:35
<ogra>
030-loopback is responsible

so waht do you think, add an option to choose between ldap users and server users? or use only ldap?
10:50Blinny has quit IRC
10:52
<Nuba1>
also... LDAP server is hardcoded to 192.168.0.254, should it be definable during --fatclient ?
10:53generic has quit IRC
10:53
<Nuba1>
maybe I should ask for LDAP url and ip during ltsp-build-client
10:54
<ogra>
if yu have a proper solution for server users add a choice
10:54
LDAP server should point to $SERVER and have an lts.conf option to override
10:54
<Nuba1>
my current proper solution would be a cron job
10:54
to synch passwd, shadow and group
10:55
<ogra>
a chronjob doing what ?
10:55
<Nuba1>
but maybe thats ugl
10:55
ugly
10:55
<ogra>
well, that doesnt realy help
10:55
<Nuba1>
y not?
10:55
<ogra>
i mean it does for running clients
10:55
but not during boot
10:55
there needs to be a basic set in the image
10:55
the prob here is that system uid's can vary
10:56
so it can only hold real user accounts
10:56Q-FUNK has quit IRC
10:56
<Nuba1>
yeah, but generally, copying everything over, seems to work
10:56
<ogra>
thats gambling
10:56
<Nuba1>
yeah, you're right :-)
10:56
hence my prior use of the word hackish
10:57
what about pulling out only the user accounts then
10:57
<ogra>
depending in which order you instll i.e. dbus and hal the uid of the hal user and messagebus user will be different
10:57
<Nuba1>
smbldap-tools already does that
10:57
<ogra>
right, you need to pull the user accounts
10:57
<Nuba1>
I can copy that procedure
10:57
<ogra>
and i wouldnt rely on rsync alone but tunnel it through ssh
10:57
its your password db :)
10:58
<Nuba1>
heh, point taken
10:58* Nuba1 is going to look at smbldap-tools and see how they do it
10:58
<ogra>
so have an ltsp specific account with ssh key who can rsync group/passwd/shadow
10:58
<Nuba1>
so build a new account just for that
10:58
<ogra>
have it monitor a token that gets touched if passwords have changed
10:59
then it can sync dynamically
10:59
<Nuba1>
but doesn't that require some sort of daemon
11:00
well, cron job I gues
11:10japerry has quit IRC
11:13
<Gadi>
if ur gonna do that, have it push rather than pull
11:13
that way you can keep the priv key out of the chroot
11:14* lns walks in, yawns
11:15
<Nuba1>
k cron job on server then?
11:15
<Gadi>
yeah - and you can just use root
11:16
create ssh keys for root on the server
11:16
copy root's *public* key to /opt/ltsp/i386/root/.ssh/authorized_keys
11:16
<Nuba1>
ah, cool, was just about to ask that
11:17
<Gadi>
and then have a cron job that checks for password changes, and then cycles through the client IPs and pushes out the new passwords
11:17
if it cant connect to a client, then no need to update its database
11:18
just make sure that the client's database has been updated on boot before you allow a login
11:18
<Nuba1>
so just cycle through list of hosts in /etc/hosts for example?
11:18
<Gadi>
so, put a script in the init.d/ of the chroot that keeps looking to see if /cow/etc/passwd exists on the client
11:19
and doesnt let the boot continue until it does
11:19
itll increase your boot time a bunch
11:19
tho
11:19
but, at least the user can login when they get a login
11:19
<Nuba1>
well, the theory is that since they are fat clients, we can leave them on
11:20
<Gadi>
well, its safer than having a priv key in the chroot that enables rsyncing of password files
11:20
:)
11:20
unless you encrypt the chroot
11:20* Nuba1 cringes
11:20
<Gadi>
in which case, you can pull
11:20
:)
11:21
<Nuba1>
this is complicated enough already... its supposed to be fun... :-)
11:21
<Gadi>
heh
11:22
what was wrong with ldap, btw?
11:22
just the added service required?
11:22
<Nuba1>
absolutley nothing... jsut thinking about alternatives
11:22
<Gadi>
ah
11:23
imho, when in fat client world, do as the fat clients do
11:23
:)
11:23
<Nuba1>
ldap is far easier than what we just talked about, but... this has the added advantage of not expecting the user to install an LDAP server
11:23
<Gadi>
just make installing the ldap server easy
11:23
and automatic
11:23
:)
11:23
<Nuba1>
well, I'm sure ubuntu is working on it... but its far from ready
11:24
try apt-getting smbldap-tools, to migrate accounts... it should put the files in /etc/smbldap, but nothing happens
11:24
<x86>
I'd like to see an LDAP directory manager for Linux (and MacOS X) that looked as simple and worked as easily as active directory's
11:24
<Gadi>
well, if you want totally insecure, there are tons of ways
11:24
:)
11:25
<Nuba1>
directory manager... use webmin
11:25
which I see is back in the repos
11:27
<Gadi>
ah, ill give you one better
11:27
<x86>
yeah but it's still not nearly as nice as AD
11:27
<Gadi>
do the push method we talked about
11:28
but have the thin client on boot make a request for the push
11:28
<x86>
I've tried most of the LDAP managers out there.... (the free ones) ... and I've come to the conclusion that they all lack ease of use
11:28
<Gadi>
that request can be checked however you like
11:28
perhaps by MAC and IP
11:28
<Nuba1>
hmmm... not bad idea...
11:28
<Gadi>
and approved or denied
11:28
that way, you dont cycle through IPs
11:29
you only dish it out to those IPs requesting
11:29
and maybe make a cron job on the client to request every so often
11:29
and on boot
11:29
<Nuba1>
yeah, that part is necessary
11:29
<Gadi>
that way, you keep the security
11:30
and get the passwords to the right places

and no ldap
11:30
<Nuba1>
sounds good...
11:31
<Gadi>
in fact, you could then make the auth as simple or complex as you like
11:31
:)
11:32
hmm...
11:32
tho, maybe this is no better than having a priv key and pulling
11:32
i think i just put the hole back in
11:32
nm
11:32
<Nuba1>
hehe...
11:34
so... conclusions is that pushing or pulling, its the same thing in the end
11:35
<cliebow>
Gadi:thanks for your help yesterday..
11:54
<Gadi>
cliebow: np - what did I do?

12:49
<Gadi>

hi
14:02
hello
14:02
anyone here?
14:02
I installed 8.04 server. I didn't get the desktop, so went through and installed the graphical desktop and now the edubuntu-desktop and edubuntu-server packages
14:02
I'm new... I click on System -> Admin and I don't see where/how to modify/setup thin clients
14:02
oh.. after installing desktop and server, I installed LTSP-manager, still don't see anything.
14:02
also, eth0 is connected to a switch. How do I set up DHCP so that it serves IPs on eth0. eth1 is my connection to my school network (windows pcs).
14:04
<cliebow>
Intrelude:still ther?
14:04
hmm
14:06
<Intrelude>
yes still here
14:07
<cliebow>
ahhh..you have installed ltsp-server-standalone?
14:07
<Intrelude>
yes, I did the sudo apt-get install ltsp-server-standalone openssh-server
14:08
and it said I have both the current version
14:08
<cliebow>
ok
14:08
<Intrelude>
I'm currently doing the ltsp-build-client
14:09
<cliebow>
i am a little out of the loop now..but you should be able to change..hang a sec
14:10
yeah /etc/default/dhcp3-server to say
14:10
INTERFACES="eth0"
14:10
<Intrelude>
ok, let me check that 1 sec
14:10
<cliebow>
and be sure your dhcpd.conf reflects the network your interface is
14:11
be sure internal and external networks are different
14:11japerry has quit IRC
14:13
<Intrelude>
ok the dhcp-server has this: INTERFACES=""
14:13
<cliebow>
must default to ethwhatever
14:13
<Intrelude>
i changed it, couldn't save it, says I don't have permissin??
14:13
<cliebow>
sudo?
14:13
<Intrelude>
i have to do this in a terminal?
14:14savetheWorld has left #ltsp
14:14
<cliebow>
best to..you could open a terminal and type sudo gedit and get away with it ..sometimes
14:15
<Intrelude>
ok got it
14:15
where is dhcpd.conf located?
14:15
<cliebow>
/etc/ltsp
14:15
shouldnt have to change ir
14:17
what address do you have for eth0?
14:17
<Intrelude>
how do I find that?
14:17
<cliebow>
ifconfig
14:17
from a term
14:17
easiest
14:18
ifconfig eth0 works
14:19japerry has joined #ltsp
14:22
<Intrelude>
eth0 Link encap:Ethernet HWaddr 00:11:d8:3c:e2:c8
14:22
inet6 addr: fe80::211:d8ff:fe3c:e2c8/64 Scope:Link
14:24
in /etc/ltsp/dhcpd.conf, I don't see any reference to eth0
14:25
<cliebow>
eth0 Link encap:Ethernet HWaddr 00:02:B3:1B:DA:82
14:25
inet addr:192.168.0.254 Bcast:192.168.0.255 Mask:255.255.255.0
14:26
system-->admin-->network is a tool to set static address on eth0
14:27
it makes changes to /etc/network/interfaces
14:28
<Intrelude>
ok, i did admin-> network and set static address to eth0 192.168.0.1 255.255.255.0 and router 192.168.0.0
14:28
is that right?
14:29
<cliebow>
it should default to 192.168.0.254...i think
14:30
router needs to be like ..hell..ill just post mine
14:31
<Intrelude>
well... eth0 is what my thin clients will be connected to. eth1 is my connectin to the schol WAN. On that I get a 10.13.16.xx address
14:32
administrator@key-app01:/etc/network$ cat interfaces
