hi all, trying to get LTSP5 on Suse 10 64bit
02:42
to be more specific, trying to get localdev working
02:44
<cyberorg>
maulanar, how do you install ltsp5:
02:44
*did
02:46
<maulanar>
followed these instructions http://wiki.ltsp.org/twiki/bin/view/Ltsp/Ltsp5TarballInstructions
02:47
<klausade>
sbalneav: didi you see my question about problem with X_RAMPERC and that ldm wont start with the X_RAMPERC patch?
02:47
<maulanar>
also had to create a soft link for the Xsession file coz Suse doesn't have it
02:48
<cyberorg>
maulanar, are you using it in production?
02:48
<maulanar>
not yet, i need to sort out this localdev issue
02:50
i followed the ubuntu debug steps (https://wiki.ubuntu.com/DebugLocalDev) and all seems ok, but still nothing on the desktop
02:50exodos has joined #ltsp

<cyberorg>
maulanar, we are working on native ltsp5 for suse see http://sourceforge.net/mailarchive/forum.php?forum_name=ltsp-developer
02:51
it is not production ready yet, but more people testing would be nice :)
02:54
<maulanar>
is there a work around in the mean time to get around the localdev issue
02:54
?
02:55
<cyberorg>
only local disks
02:56
<maulanar>
i meant to get localdev working, is there some hack?

<garbat>
Blank to all. What I must modify in order to add an other thin client to my system? I have understood that enough not to modify dhcpd.conf why the client endured blinking jams with an hyphen after to have had IP address
02:57
<cyberorg>
maulanar, yes, but only of local harddisk, usb and cdroms
02:58
<maulanar>
cyberorg: very cool! that's really all i'm interested in right now. how do i get it to work?
02:59
<cyberorg>
maulanar, see at the bottom of this page http://en.opensuse.org/LTSP

hey hey

<dberkholz>
evening/morning, ogra
04:26

04:28

nearly noon here ... i think i'll be mediocre today and pick europe :)
04:29
<dberkholz>
X summit going this week. i'm not there, but thought you might like to know there's someone representing thin clients
04:29
<ogra>
maulanar, you need the ltspfs package on the server
04:29
<cyberorg>
maulanar, ssh into the client and find out where it mounts stuff and mount that folder on the user's session using ltspfs
04:29
<dberkholz>
from someplace called ndiyo or something like that
04:29
<ogra>
never heard of that
04:29
but thats intresting
04:31
cyberorg, there is an error in the suse page:
04:31
"Note: This needs to be done by LTSP5's delayed_mounter script, which needs to be fixed to work with openSUSE"
04:31
must be
04:31
"Note: This needs to be done by LTSP5's ltspfsmounter script, which needs to be fixed to work with openSUSE"
04:31
<cyberorg>
ogra, delayed_mounter is gone?
04:31
<ogra>
(thats on the server side, delayed_mounter is client side)
04:32
no, but delayed mounter cant create dirs on the server ;)
04:32
<maulanar>
ogra: ltspfs installed. box is 64bit but had to install 32bit version of fuse to get it work on ltsp4.2u3
04:32
<ogra>
oh, well, aned its gone as well in favor of new ldm scripts
04:32
<maulanar>
cyberorg: drives are being mounted to /var/run/drives
04:32
<dberkholz>
ogra: ltsp got any use for the new input hotplug stuff in X?
04:32
<maulanar>
browsing shows empty dir
04:32
<ogra>
maulanar, ltspfs from 4.2 isnt remotely compatible with what ltsp5 does
04:33
you need the package from ubuntu (or at least all scipts from it, ltspfs itself didnt change that much, but its integration)
04:33
<maulanar>
ogra: where do i get ltspfs package for ltsp5?
04:34
<ogra>
no idea where to get it for suse, sorry
04:34
<maulanar>
ogra: source?
04:34
<ogra>
you could probably use something like alien to convert it
04:34
the yource package is here: https://launchpad.net/ubuntu/+source/ltspfs
04:35
*source
04:35
<cyberorg>
maulanar, http://download.opensuse.org/repositories/home:/cyberorg/ has ltsp-server package
04:35
<Daggett>
I've searched for a while and on the wiki, but still can't find how to get USB sticks to work on the clients, All seems OK, but it deosn't work, any help?
04:35
<cyberorg>
sorry, you'd need ltspfs and ltspfs-server packages
04:35
<ogra>
maulanar, the plain C code for the binaries is in this bzr branch https://code.launchpad.net/~sbalneav/ltspfs/ltspfs-upstream
04:36
Daggett, which ltsp release/distro
04:36
<Daggett>
4.2
04:36
Mandriva 2007.1
04:36
<ogra>
there is a troubleshooting page on the ltsp wiki
04:37
<Daggett>
ogra: I've read it, and I'm stucked at step 11 of the http://wiki.ltsp.org/twiki/bin/view/Ltsp/LTSP-42-LocalDev page
04:38
All seems OK, but nothing is ever mounted anywhere
04:40* ogra is not very familiar with that old code ... its unmaintained since 2 years now ...
04:40
<Daggett>
It had worked in the past, and it always have been quiest easy to set all things up, and in 10 minutes rhe USB storage things where working, but this time, I can't figure out what's wrong
04:40
<ogra>
Daggett, best to wait if sbalneav shows up here
04:40
<Daggett>
ok, thanks, I'll wait
04:42
<maulanar>
cyberorg: which ltsp-server package should install, 64 or 32 bit?
04:43
<cyberorg>
maulanar, depends on your server, you just need ltspfs package if using ubuntu tarball
04:44
<maulanar>
my server is a 64 bit machine, but i had problems with localdev on 4.2 when i installed 64 bit version of fuse
04:44
installing 32 bit version fixed the problem
04:45
<cyberorg>
maulanar, run 'arch' use that one
04:46
if you installed 64bit suse, use x86_64, if it shows ix86, use i586 packages

05:14

ummm..hav to look at school
05:55
<maulanar>
cyberorg: downloaded installed ltspfs and fuse (2.6 required) and seems to be working
05:55
<cyberorg>
maulanar, cool :)
05:56
<maulanar>
problem now seems to be that clients slow down after logging in and out several times
05:56
and also need an automagic script to automatically mount media dir
05:58
<cyberorg>
maulanar, do you hack ?
05:59
<maulanar>
cyberorg: ?
05:59
<cyberorg>
maulanar, do you do programming?
06:02
<maulanar>
cyberorg, no
06:02
<cyberorg>
k
06:06
<maulanar>
cyberorg, where is the delayed_mounter script called from?
06:06
<cyberorg>
maulanar, that is on the client
06:06
ltspfsmounter is in server
06:07
maulanar, if you are planning to look into that, don't, as new ldm2 obsoletes all that
06:07
<maulanar>
cyberorg, ok. when is ldm2 available
06:07
?
06:08
<cyberorg>
maulanar, it is under development, but you can get the test packages as mentioned in the ltsp-devel post
06:10
<maulanar>
cyberorg, thanks a lot for the help man, really appreciate it
06:10
looks good now, devices are being mounted in the media folder automatically
06:11
just need to disable mounting of floppy and i'm smiling!!

maulanar, sorry lost internet connection there, " you can get ldm2 in the test packages as mentioned in the ltsp-devel post"
06:38
<ogra>
cyberorg, note that the new security mechanism in ldm2 will require the ltspfs(d) 0.5 packages
06:39
<cyberorg>
ogra, from here? https://code.launchpad.net/~sbalneav/ltspfs/ltspfs-upstream
06:40
<ogra>
yeah
06:41
<cyberorg>
ok, will update those as well :)
06:41
<ogra>
:)
06:41
paths changed and ldm set an mcookie for authentication now ...
06:41
<cyberorg>
ogra, how do we identify if we are running nfs root or nbd root, is there an option in lts.conf?
06:41
<ogra>
without that you wont be able to mount anymore
06:42Avatara has quit IRC
06:42
<ogra>
well, in ubuntu/debian you can see it in the BOOT= variable of initramfs
06:42
<cyberorg>
i've no idea what you said, but i'll try and get that working :p
06:42
<ogra>
if thats set to ltsdp-nbd, the initramfs will expect an nbs image on the server
06:43
*nbd
06:43
<cyberorg>
ogra, i wanted to know for bind mounts thing, i do not need to run those if we are using nbdroot, as it uses aufs
06:44
<ogra>
right
06:44
if you use unionfs/aufs you wiont need bind_mounts()
06:44fernando1 has quit IRC
06:44
<cyberorg>
in init script i would have to put something like if nfs then; bind_mount,
06:44
<ogra>
we have a variable for that
06:44
<cyberorg>
is that specified in lts.conf?
06:45
<ogra>
root_write_method="unionfs"
06:45
<cyberorg>
where?
06:45
<ogra>
its specified in /etc/default/ltsp-client-setup in the client chroot
06:45
which is sourced by the initscript
06:45
<cyberorg>
ok, will change there
06:46
<ogra>
if thats set, the client relies on unionfs making the root writeable
06:48
<cyberorg>
ogra, that is handled by kiwi netboot image for us, it uses aufs, or unionfs in that order according to availability
06:49
<ogra>
yeah, what i meant is that you have to take care elsewhere :)
06:49
<cyberorg>
bind mounts are handled by ltsp-client.init script
06:49
<ogra>
the script simply wont do anything
06:49
right
06:49
<cyberorg>
i'll put if clause there so bind mounts are only run when using nfs
06:50
<ogra>
right
06:50
we should automate that :)
06:50
<cyberorg>
captain_magnus, did you get nbdswapd working using xinetd ?
06:50
<captain_magnus>
cyberorg: No, not yet... Didn't look at it again today...
06:51
<cyberorg>
i saw one change in your last commit :)
06:51
<captain_magnus>
It executes the script alright but nbd-server returns a 1, which seems to indicate that xinetd doesn't supply the stream to stdin (or something like that)
06:51
cyberorg: Don't mind that commit... It doesn't work :-)
06:52
<cyberorg>
ogra, anyone uses nbdswap with xinetd?
06:52
the altlinux guys?

morning
07:00
<ogra>
cyberorg, not that i'm aware of
07:00
i think even alt doesnt use nonfree licensed tools in their default :)
07:00
<BlackDark>
ogra : is that a way to limit how much memory xorg could use on the terminals ?
07:01
<ogra>
BlackDark, only in the latest development version, it was recently added
07:01
<BlackDark>
I have an anoying bug with that : when a user open a web page with a lot of big pictures, it endup to freeze the terminal
07:01
<ogra>
BlackDark, how much ram do the clents have ?
07:01
<BlackDark>
128 megs
07:02
<ogra>
that should be plenty
07:02
<BlackDark>
16 megs are dedicated for the videoram
07:02
so 112 megs of ram
07:02
I use the stock version of ltsp of feisty
07:02
I got the problem with firefox and evince

07:06
the change to teh screen.d script is what you want, it needs to happen in /opt/ltsp/i386/usr/lib/ltsp/screen.d/ldm
07:06
then you can set X_RAMPERC in lts.conf
07:07
<Blinny>
Hot topic lately.
07:07
<ogra>
(laternatively you could just set "ulimit -v 100M" or so on /etc/rc.local in the chroot
07:11fernando1 has joined #ltsp
07:11
<BlackDark>
if I onnly set the ulimit to 100M, what gonna happen ? just to kill the session ?
07:24
ok, just noticed the code to add to ldm
07:24
it's gonna set the limnit
07:33fernando1 has quit IRC
07:38
<ogra>
it will crash firefox rather than the whole system
07:39
not a big improvement, but at least prevents dataloss
07:39
the real fix needs to go into FF
07:40
<BlackDark>
off course
07:41MagicStorm has joined #ltsp
07:49
<BlackDark>
ogra, what kind of values can set to X_RAMPERC in lts.conf ?
07:49
can I put somehting like 100M ?
07:50Guaraldo has joined #ltsp
07:50
<ogra>
i think so
07:50
it shoul be documented in the 4.2 docs anywhere on ltsp.org i guess
08:07
<sbalneav>
Morning all
08:07
<BlackDark>
morning
08:09
where is stored ltsp-update-image on feisty ?
08:11
<sbalneav>
It isn't there on feisty. It's new for gutsy.
08:11
<ogra>
it doesnt exist in feisty
08:11
<BlackDark>
ok
08:12
<ogra>
(thats why feisty is so much slower than gutsy ;) )
08:13
<BlackDark>
the keepalive thing for nbdrootd, does it have to be on the client or the server ?
08:14
<ogra>
server
08:15
it triggers the tcp wrapper of inetd to check if the connection is alive
08:19
<BlackDark>
so if I put the ulimit thing in my rc.local at the client side, it's gonna prevent the terminal freezing, right ?
08:20monteslu has joined #ltsp
08:20
<ogra>
it should, yes
08:21
<BlackDark>
ok good thanks
08:21
can I apply that without rebooting the terminal ?
08:22
I understand if I set the limit in a console, it';s gonna apply that only for the logged in user
08:22
<ogra>
you need to reboot

ogra : I putted : ulimit -v 102400 in my etc/rc.local, but the limit doesn't seems to be there
08:44
after the reboot, if I do a ulimit -a the virtual memory is still unlimited
08:44
<sbalneav>
BlackDark: in dash, use ulimit -m
08:45
<ogra>
yeah, i pointed you to the older version with ulimit -v in the code, sorry
08:45
<BlackDark>
np
08:48
ok I can set the memory limits with ulimits but what's the difference with /etc/security./limits ?
08:49
limits.conf sorry
08:55
<ogra>
that sets system wide limits
08:56subir has quit IRC
08:56
<ogra>
running the ulimit in the screen.d script will only limit it for the current and subsequent processes (X and friends)
08:56* ogra shows off with knowledge sbalneav just tought him ;)
08:57tux_440volt has quit IRC

I've got at least 4 boxes that are completely fried

They blew the circuit breakers. I'm sitting here with a blackened power bar. Gonna try to open up one of the monitors, see how bad the damage is. Maybe I can just replace some caps.

i kinda disappeared there for a bit heh.

13:02
<ltsppbot>
"vagrantc" pasted "patch to screen_session" (24 lines) at http://pastebot.ltsp.org/314
13:02
<vagrantc>
sbalneav: check that patch out ... i think it's easier to read, and one line shorter.
13:03
sbalneav: though i'm wondering if that code block ever gets executed ... it's in an if statement, and i *think* the first if statement is the one that gets used.
13:07
<sbalneav>
vagrantc: Ah, nicely done.
13:08
<vagrantc>
sbalneav: :)
13:08
sbalneav: though i think we can safely drop the /dev/vc/ stuff
13:09
<sbalneav>
yeah, I don't think it ever gets executed at all.
13:09
yeah, vc was 2.4, was I right?
13:09
<vagrantc>
devfs, i think
13:09
<sbalneav>
right.
13:09
yeah
13:09
<vagrantc>
so on some older 2.6 it was there
13:09
<sbalneav>
I think all the distros have switched to udev by now, eh?
13:10
<vagrantc>
i'magine
13:10
so, looking at the code execution ... i think i see when that code block gets executed ... it's crazy, really...
13:10
<sbalneav>
Yeah, it's if it's called with no params.
13:11
THEORETICALLY :), what we could do is either 1) start screen_session from inittab or 2) upstart. I think that's what it's for.
13:11
<vagrantc>
well, it calls itself when called with a param
13:12
it is some crazy-ass redirection there
13:12
<sbalneav>
really? *looks*
13:13
<vagrantc>
i think the init script calls it, it figures out why tty it should run on, and then exec's itself on the new tty ...
13:13
<sbalneav>
exec <$TTY >$TTY 2>&1 ? That re-calls itself?
13:13
<vagrantc>
what do you think it does ?
13:14
admittedly, i'm confused.
13:14
<sbalneav>
I thought it was simply re-directing standard in from $TTY, and out.
13:14
not re-executing the script.
13:14
<vagrantc>
i'll believe you.
13:14
<sbalneav>
Don't ! :)
13:14
here, lemme try something...
13:18
#!/bin/sh
13:18
exec </dev/tty10 >/dev/tty10 2>&1
13:18
while true; do
13:18
echo "FOOO"
13:18
read X
13:18
echo $X
13:18
done
13:18
yeah, it just makes /dev/tty10 your stdin and stdout.
13:19
so the case stuff's just if it's started from inetd/upstart, and is ALREADY set a controlling terminal to that tty, and so passed with no params.
13:20
i.e. you could do a 2:23:respawn:/usr/lib/ltsp/screen_session
13:21
since you're already on tty2, the case code gets called
13:21ogra has joined #ltsp
13:21
<sbalneav>
So, I guess the question is: for the sake of simplification, do we want to eliminate that, since we don't bother adding commands to the inttab?
13:22Gadi has left #ltsp
13:22
<sbalneav>
vagrantc: thoughts?
13:24
<vagrantc>
sbalneav: it's not a huge amount of code to maintain for additional flexibility, especially if we put a couple comment lines in explaining likely uses
13:24
<sbalneav>
ok, lets leave it in, but ditch the vc stuff?
13:24
<vagrantc>
sure
13:24bobby_C has joined #ltsp

13:28

hopefully getting a new upload to debian based on 5.0.27

I added some comments.
13:29
<ogra>
what are you guys conspiring again here ?
13:29
<vagrantc>
where else are we gonna conspire?
13:30
<sbalneav>
heh, we just made a small cosmetic change in screen_session. Removed some old 2.4/devfs code that was superfluous.
13:30
but if it piques your interest more, we're PLANNING TO TAKE OVER THE WORLD, MUAHAHAHA
13:30
<ogra>
still 2.4 code ?
13:31
i thought that was finally gone :)
13:31
<jammcq>
ogra: don't worry, i'm watching over them
13:31
<mistik1>
lol
13:31
<ogra>
:)
13:31
<vagrantc>
right, that's why we should conspire somewhere else!
13:31
<sbalneav>
yeah, looking for /dev/vc/1 as well as /dev/tty1
13:31
<mistik1>
happy hackers makes for good code
13:31

13:31

jorgec, incognito, eh ?
13:31
<vagrantc>
screen_session requires bash ? :(
13:32

13:32* jammcq wonders if ogra is confusing mistik1 for whiprush

hi

<Blinny>
Hello.
13:35
<vagrantc>
sbalneav: don't know if there's a bash'ism, but it's got #!/bin/bash
13:37
<sbalneav>
*looks*
13:37
So it does.
13:37
Wonder what other bash's we've got in there.
13:37
lets fix that.
13:38
there's nothing in there that should be bash specific, I'm going to do a quick grep -r for bash, see what other squirmy things are hiding under rocks
13:39
<vagrantc>
i think we use some bashisms for ltsp-build-client, but that shouldn't be a problem.
13:39
<sbalneav>
No, that's ok.
13:41
<ogra>
no, its not
13:41
but not bad enough to delay a release :)
13:45
<vagrantc>
i seem to recall implementing something in ltsp-build-client that was an order of magnitude simpler with some features in bash. sure don't remember what...
13:47
<ogra>
there were some bashisms iirc and it was close to release for one of us (if in doubt that was me) and we decided to postpone a proper fix
13:49
jammcq, can you bring me a riser card for the T170 to boston ?
13:49* ogra got a DVB-S HD card on the weekend ...
13:50
<jammcq>
ogra: sure, if you remind me. although I'll warn you that the riser card doesn't provide 12v, only 5v which is a problem on some pci cards
13:50
<ogra>
ah, well ...
13:50
i'll have to look up the documentation for the card
13:50
<jammcq>
and you usually can't tell if you need 12v until you actually try it

Has anyone had success using wine/Firefox in an LTSP environment, along with Flash/shockwave plugins?
13:59
I'm running into a roadblock because I *need* shockwave functionality in Ubuntu/LTSP
13:59
<ogra>
there is no shockwave for linux so you mean you want to run FF for windows under wine ?
14:00
<lns>
ogra, correct (and hello!)
14:00
<ogra>
wow, weird setup
14:00
<lns>
yeah
14:00
the school district i'm working with right now has a couple of websites with SWF enabled games/educational tutorials that they've been using for years
14:01
<ogra>
well, swf (flash) shouldnt be any problem
14:01
<lns>
oh..maybe i said it wrong...it is shockwave (I thought that was swf along with flash)
14:01
they require shockwave..i'm using FF32 for flash and that works ok (with no sound)
14:03
<ogra>
you need libflashsupport
14:03

is that re: flash sound?
14:04
<ogra>
yes

ok, ty
14:04

but i doubt adobe will ever release shockwave for linux ...
14:04
<lns>
i seriously can't believe adobe doesn't have one already
14:05
have you seen the online petition for it? 26k signatures??
14:05

no, i heard about it though

well, they likely have a BSD compatibe one for OSX

14:06
<ogra>
thanks :)
14:06
<lns>
ogra, if that were the case I would have thought it would have been done by now... maybe it just needs to be suggested
14:07
i see adobe's website has shockwave player available for osx download
14:07
so i guess they're clenching tightly
14:11
ogra, is there a libflashsupport for 64-bit arch?
14:11
<ogra>
there is the source
14:11
you can build it

ok

Should I be able to see the results of XRAMPERC in 'ulimit -a' on a client's console?

Ah. Thank you.

Blinny, memory problem with firefox or so ?
14:15

Memory problem with something.
14:15
<BlackDark>
try to open that page with the terminal : http://www.carteretcountyschools.org/bms/teacherwebs/sdavenport/artgallery6.htm
14:15
you gonna see if it's a x memory problem

Dude. There's lots of problems in the world you could helping to solve, instead you're in #ltsp asking how many layers of aluminum foil to wrap things in?
15:13

joebaker, it's not really true

I mean... Is it a verb?
15:25
<vagrantc_>
more of a noun
15:25
<sbalneav>
Yeah, you can say "I'm going to kludge something together", or "I kludged a solution up for that bug". Keep it mind it's not a "real" word.
15:25
<vagrantc_>
well, i guess it can be both
15:25

it's slang

I thought you figured out that keyboard problem?
15:27

sbalneav: Taking all binary packages and liberies of Xorg 7.1.1 and unpacking in LTSP 4.2 chroot... I'm still testing the solution...
15:28
sbalneav: Yep... upgrading Xorg of LTSP 4.2
15:28
sbalneav: I don't know yet whitch new problems ome with my kludgy solution...
15:29
sbalneav: But I already booted a thin with Xorg7.1.1
15:29
<sbalneav>
What I don't understand is: rather than doing all that work on ltsp 4.2, which is essentially dead, why not work with me to figure out what you need in ltsp5, and work on that?
15:30

17:38
any ideas?
17:39
err, it actually says "eth0: setting half-duplex" then it hangs
17:40
<vagrantc>
drwahl: which linux distro ?
17:40
<drwahl>
debian
17:41
<vagrantc>
drwahl: similar to this issue: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=395145 ?
17:42
<drwahl>
similar, but not the exact same
17:43
rather, the text that has been outputted is different
17:43
<vagrantc>
and it hangs indefinitely ?
17:44
<drwahl>
yup
17:44
and i have no control
17:44
or prompt rather
17:45
<vagrantc>
drwahl: are you able to test with a cross-over cable instead of a hub ?
17:46
<drwahl>
not really. i have a dhcp server that is seperate
17:46
so 3 comps are involved
17:47
are you trying to rule out the switch? because i have about 40 of them at my disposal
17:47
<vagrantc>
yes, rying to rule out the switch ...
17:47
drwahl: and how many thin clients behave like this ?
17:48
<drwahl>
lemme try a few other switches real quick (though i do not suspect it to be the problem). i have about 10 clients all doing the same thing
17:48
<vagrantc>
ogra: i wouldn't recommend merging scotty's latest changes into ubuntu ...
17:48
needs a little more work ...
17:53

17:57
hrm.
18:23

so no more ideas? :)

no.

18:28* vagrantc gives up struggling and reverts
18:28

haha
18:36
might it be related to the NIC driver?
18:37
<Ryudo>
ogra
18:37
<vagrantc>
drwahl: might be ... any idea which driver they're using ?
18:37
<drwahl>
its an onboard NIC on a Gateway machine. i believe it is intel
18:38
<Ryudo>
vagrant do you have ltsp5 technical documentations ? pdf ...
18:39
i need some technical documentation of ltsp5 works
18:39
<vagrantc>
Ryudo: there is very little documentation ... what do you need to know ?
18:39
<Ryudo>
booting process
18:40
you send me all you documentation ?
18:40
<vagrantc>
Ryudo: could you be more specific? or do you want a very general overview ?
18:40
Ryudo: i have nothing
18:41
Ryudo: no documentation you don't already have on the various wiki pages ...
18:41
<Ryudo>
I am going to do an academic work
18:42
<vagrantc>
i just don't understand what sort of information you're looking for ...
18:42
i can explain the boot process in a single line
18:42
<drwahl>
vagrantc: ok, i tried with a laptop (different NIC) and it gets past the eth0 part, but fails to mount the nfs
18:43
<vagrantc>
PXE loads, gets a DHCP request, downloads a kernel and initramfs image via TFTP, kernel loads initramfs, initramfs makes a DHCP request, mounts it's root filesystem (either NFS or NBD+squashfs+unionfs), initramfs switches to the root filesystem
18:43
<Ryudo>
I need to know in detail of boot process (interaction between terminal and server) ldm (XDMCP is not more used?)
18:43
<vagrantc>
Ryudo: does that answer your question ?
18:44
<Ryudo>
vagrant thx but the ldm
18:44
how this works ?
18:44
XDMCP ?
18:44
X over ssh ?
18:44
<vagrantc>
drwahl: can you mount from the server itself ? i.e. mount -o ro,nolock 127.0.0.1:/opt/ltsp/i386 /mnt
18:44
<Ryudo>
sorry but my english is so poor
18:45
<vagrantc>
Ryudo: LDM uses X over ssh by default, yes.
18:45
<Ryudo>
hum
18:45
<drwahl>
vagrantc: tried as root, and i get permision denied
18:46
<vagrantc>
!nfs
18:46
<ltspbot>
vagrantc: "nfs" is the protocol that serves the files needed by LTSP. You can find info at http://wiki.ltsp.org/twiki/bin/view/Ltsp/NFS
18:47
<vagrantc>
drwahl: have you configured /etc/exports ?
18:47
<Ryudo>
PXE loads, gets a DHCP request, downloads a kernel and initramfs image via TFTP, kernel loads initramfs, initramfs makes a DHCP request, mounts it's root filesystem, initramfs switches to the root filesystem and after connect on X server over SSH using LDM right ?
18:48
pxe or etherboot correct ?
18:48
<vagrantc>
Ryudo: that's about it
18:48
sure
18:48
<drwahl>
vagrantc: ya, but i think i had the wrong dir set. i moved the location of ltsp-client-build
18:51
<vagrantc>
well, that'll do it...

<drwahl>
i just keep getting "mount call failed: 13"
19:02
<vagrantc>
drwahl: after you've fixed /etc/exports to have the proper path, did you restart nfs-kernel-server ? invoke-rc.d nfs-kernel-server restart

exportfs: /etc/export [2]: Niether 'subtree_check' or 'no_subtree_check' specified for export "*:/var/opt/ltsp/swapfiles
19:04
will that mess something up?
19:04
<vagrantc>
comment out the swapfiles line
19:04
that's for ltsp 4.x
19:04
<drwahl>
ah
19:04
<vagrantc>
i haven't see problems with ltsp using or not using subtree_check
19:06
<drwahl>
exportfs: /etc/export [1]: Niether 'subtree_check' or 'no_subtree_check' specified for export "*:/tftpboot/i386"
19:06
showmount -e says that it is there
19:07
<vagrantc>
drwahl: can you paste your /etc/exports to the pastebot ?
19:07
!pastebot
19:07
<ltspbot>
vagrantc: "pastebot" is The LTSP pastebot is at http://pastebot.ltsp.org. Please paste all text longer than a line or two to the pastebot, as it helps to reduce traffic in the channel. A link to the content will be pasted in the channel.
19:07
<drwahl>
just fyi, all my onboard intel NICs hang on setting eth0 to half duplex. might be a driver issue
19:08
my exports file can be found at http://drwahl.ath.cx/exports
19:09* vagrantc curses
19:09
<vagrantc>
the latest ldm is not cooperating with the gnome in debian lenny
19:10
<ltsppbot>
"drwahl" pasted "/etc/exports" (13 lines) at http://pastebot.ltsp.org/315
19:12
<vagrantc>
drwahl: i recommend (ro,no_root_squash,async,no_subtree_check) for options
19:12
<drwahl>
ah, lemme try taht
19:16
still getting nfs mount error 13
19:16
<vagrantc>
drwahl: try mounting via 127.0.0.1 ?
19:17
<drwahl>
works on the nfs server, but the clients still cant seem to get it
19:17
<vagrantc>
ok, well ... that's progress
19:18
drwahl: grep root-path /etc/*/dhcpd.conf
19:20
<drwahl>
i'm using Smoothwall 3.0 as my router, which handles dhcp, and network boot stuff. i set the rootpath on that as /tftpboot
19:20
might it be a permissions issue?
19:21
<vagrantc>
drwahl: set it to /tftpboot/i386
19:22
<drwahl>
when i set it to that, it cant find the pxe image
19:23
<vagrantc>
what have you set for filename?
19:24
<drwahl>
with /tftpboot as the root path, i have /i386/boot/pxelinux.0 for the image, and it boots fine. if i change the root path to /tftpboot/i386, and the image to /boot/pxelinux.0, the clients cannot find the image
19:26
<vagrantc>
don't know what to say. dhcp3-server doesn't behave that way.
19:26
<drwahl>
odd
19:27
maybe it isnt dhcp3... lemme do some research
19:27
<vagrantc>
i'd recommend setting up a separate DHCP server for your LTSP network ... put a second network card in your LTSP server and physically split up your network
19:28
root-path and filename should be two unlrelated options
19:29
as far as your dhcp server is concerned
19:29
<drwahl>
what about tftp
19:29
<vagrantc>
well, tftp should just be downloading whatever your dhcp server is telling it to download
19:29
<drwahl>
might i need to set tftp-root to /tftboot/i386 ?
19:29
<vagrantc>
how's your tftp server configured ?
19:30
<drwahl>
i'm using atftpd, but i think it is using inetd (if that even makes sense)
19:30
<vagrantc>
grep tftp /etc/inetd.conf

i need to change the /opt/ltsp to /tftpboot
19:34
right?
19:34

drwahl: why do you need to move all this stuff to other places ?
19:35

uh... no reason really, just habbits

19:37

default setup is /var/lib/tftpboot for tftp and /opt/ltsp for NFS ...

vagrant sorry, but whats is pxelinux.0 ?

i lost ¬¬
19:58

Ryudo: it's a boot loader that is supported by pxe, a branch of syslinux, which is another boot loader
19:59fgiraldeau has joined #ltsp

<fgiraldeau>
hi there
20:00
<Ryudo>
etherboot (floppy) call for pxelinux.0 and this load de kernel and kernel mount /opt/ltsp/i386 over nfs right ?
20:00
<vagrantc>
Ryudo: basically
20:01
<Ryudo>
in newest motherboard the onboard LAN have a etherboot into you ROM ?
20:02
<vagrantc>
most newer motherboards support the PXE protocol
20:03
er, newer network cards
20:04
<Ryudo>
pxe protocol is diferent of etherboot ?
20:05

yes

hey francis
21:12
doing great
21:12
how's things over there in quebec ?
21:12
<fgiraldeau>
Not too bad after all
21:13
I'm working to get our first ubuntu ltsp mille-xterm cluster (I even don't know how to name it)
21:13
And what about you?
21:13
<jammcq>
i'm working on some customer things. gotta pay the bills, ya know
21:14
<fgiraldeau>
for sure
21:17
I'm realy exited about the idea to participate to UDS in boston.
21:18
<jammcq>
yeah, it's a blast
21:18
<fgiraldeau>
Can you describe the ambiance?
21:18
<jammcq>
umm, 80-100 geeks that just want to produce the best software possible
21:19
then, at night, we go off to dinner and have some wine and a good time
21:19
then, 9am the next morning, do it again
21:20
<fgiraldeau>
It's a good planning
21:20
<jammcq>
it's very intense
21:20
<fgiraldeau>
I like intense things
21:21
I'm gonna take couple of days off before this event, to recharge my batteries :)
21:21
<jammcq>
cool
21:22
we're possibly going up to Maine for a few days afterwards to have some lobster and beer and unwind a bit
21:22
<fgiraldeau>
It's a litle bit late, you're working yet?
21:22
<jammcq>
yeah, I work until about 12am or so
21:23
<fgiraldeau>
lobsters: cool. You're going there by car? I will come by car myself to boston.
21:23
<jammcq>
yeah, i'm thinking about it
21:24
during the week I won't need it, but it'll be very handy for going up to Maine
21:24
<fgiraldeau>
It's pretty near of Sherbrooke, about 4 hours and half.
21:25
<jammcq>
yeah, it's more like 10-12 hours for me
21:25
<fgiraldeau>
Outch.
21:25
<jammcq>
but I have a customer in Rochester, NY that I can stop at and visit
21:25
always good to visit the customers
21:25
plus, I have a very comfortable car, with good music
21:25
<fgiraldeau>
you're right, nothing like a real meeting to get things done quickly
21:26
What are you driving?
21:26
<jammcq>
chevy suburban
21:26
nice and big
21:26
<fgiraldeau>
My god!
21:26
<jammcq>
I could prolly fit your car in the back of mine
21:26
and still have room for 4 people and luggage
21:26
<fgiraldeau>
yeah, probably!
21:27
I do have a litle diesel volks, so it will cost about 25$ of diesel to come to boston. Not too bad.
21:28
<jammcq>
wow. It'll cost me a bit more
21:28
<fgiraldeau>
Yeah, I think
21:28
<jammcq>
I'm hoping that scotty will fly here to detroit and drive with me. that's always a good time
21:29
<fgiraldeau>
He don't know yet?
21:29
<jammcq>
we haven't firmed up the arrangements yet
21:29
<fgiraldeau>
Well, with 12 hours of driving, you get a lot of time to talk.
21:30
That's not loosed time
21:30
I heard that he worked hard on the project recently.
21:31
I send him the server section of the edubuntu handbook, about multiple server support.
21:31
<jammcq>
cool
21:31
<fgiraldeau>
I'm pretty sure he's tired after this blitz, I didn't have news of him.
21:32
<jammcq>
he'll probably pop in here soon
21:33
<fgiraldeau>
So, he's a night bird :)
21:33
<jammcq>
yeah, plus he's an hour behind us
21:33
<fgiraldeau>
He will come when I will go to sleep.
21:34
I don't know how these guys are doing for beeing always up.
21:34
There is no justice.
21:34
Will you reserve at the proposed hotel for UDS?
21:35
<jammcq>
I plan on it
21:35
<fgiraldeau>
I imagine that all activities are held in this hotel.
21:35
<jammcq>
yes, although there might be an offsite dinner
21:35
<fgiraldeau>
It's a litle bit costly, I do have to sell that to my boss
21:37
Maybe the $CAN will be over the $US soon, so it will help :)
21:38
Anyway, I prefer to be in the same hotel, because I want to focus on the team work.
21:38
<jammcq>
yes, that's very important
21:39
that way, we all spend the entire day together, starting with breakfast
21:39
<fgiraldeau>
If you said it, my boss will say ok :)
21:40
Thanks a lot again for all your tips.

<MrChicken>
Hello
23:11
I'm running ltsp 5... and I was wondering how can I prevent some users to access internet (I want to restrict them to the local domain only)
23:13
<sbalneav>
You'd need to set up a transparent proxy to something like squid
23:13
<MrChicken>
hrmmm so I feared
23:14
but squid only works by IPs
23:14
and since all the connections come from the ltsp server...
23:14
<sbalneav>
You'd need to make an authenticating proxy.
23:15
<MrChicken>
ouch
23:15
<sbalneav>
Not too hard.
23:15* MrChicken was happy when he found ebox... now he has to get rid of it :s
23:16
<MrChicken>
ebox = smething like webmin for dummies
23:16
anyway... I wanted to ask you... do you know any good admin interface thats 'user-friendly'?
23:17
<sbalneav>
/bin/bash?
23:17
<MrChicken>
lol
23:18
kinda hoped for something like webmin, but easier
23:18
<str4nd>
/bin/zsh! :)
23:18
<sbalneav>
What, webmin's not easy?
23:19
<MrChicken>
u still gotta do the editing
23:19
:P
23:19* MrChicken is lazy
23:20
<MrChicken>
ah welll
23:20
I guess you cant have it all :P

23:49
<sbalneav>
drwahl: Whan version of ltsp are you using, on what server?
23:51
<drwahl>
i am running Debian sid, and i got it from "apt-get install ltsp-server"
23:51
<sbalneav>
Well, you probably need to do an ltsp-update-sshkeys.
23:52
as for startiing in init 5, it should start in anything 2 or above, I think
23:52
brb, shifting to downstairs machine...

Can you paste your lts.conf file?
