<bluedragon>
hello all
03:47
I'm trying to get LTSP 5 running under ununtu 7.04
03:48
I've got it to boot finally
03:48
It now stops at "Loading hardware drivers"
03:48
after mounting the nfs
03:48
any ideas anyone
03:51
<ogra>
drop "quiet splash" from the line in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
03:52
then boot again and look what the error is
03:52
<bluedragon>
not using pxe using etherboot.
03:53
<ogra>
that shouldnt make a difference
03:53
ltsp configures both by default since edgy
03:53
<bluedragon>
apart from etherboot not reading pxelinux.cfg
03:54
<ogra>
err, right :)
03:54
<bluedragon>
hang on that gives me an idea
03:57
change the mknbi-linux line and add "quite splash" to the append parameers
03:58
I get a fancy splash screen.
03:58
so I can safly say I was not using quiet splash in the first place.
04:01vanya has quit IRC
04:02vanya has joined #ltsp
04:03
<bluedragon>
however I've now changed the append="rw" to append="ro"
04:03
and now I get Loading hardware drivers [FAIL]
04:03
LOading kernel modules
04:04
Loading manual drivers
04:04
then it stops
04:05
oh eventally with the splash screen it said somthing about time stamps but then my thin clients do not have a battary so proabably no clock!

<phanste>
hello
04:28
is it possible to install a bootsplash on ltsp-4.2 please ?
04:39
someone can answer me please ?
04:40
<bluedragon>
yes
04:41vanya has joined #ltsp
04:41
<phanste>
you think it's possible without recompile the kernel ?
04:41
<bluedragon>
phanste: 4.1 instructions work with 4.2 but you do need to recompile the kernel
04:42
<phanste>
can you explain me please and where i can find 4.1 instructions ?
04:44
<bluedragon>
http://wiki.ltsp.org/twiki/bin/view/Ltsp/CustomLtspKernels
04:44
and apply the right patch for bootsplash
04:44
I will own up I've never done it my self.
04:44spectra has quit IRC
04:45
<bluedragon>
I tend to avoid sill graphical boot screens.
04:45
At least if it all stops working somone can read somthing to me with nice text!
04:46Q-FUNK has joined #ltsp
04:47
<phanste>
thanks bluedragon
04:48
i will try it
04:50
i have try the kernel on this page with ltsp-4.2
04:50
http://wiki.ltsp.org/twiki/bin/view/Ltsp/BootsplashPatch
04:50tyndyll has left #ltsp
04:51
<phanste>
but at end of boot , he ask me a runlevel , i think it can't read iniitab
05:05
<bluedragon>
hmm after rebooting several times and it stopping in different places everytime I think the problem might be memory
05:07
theory runs that if the initrd for ltsp is so much bigger the client is going to need more memory to work
05:07
and its going to need this before it can bring up swap
05:08
hmm I've only got 24Mb in my clients
05:09
memory has always been tight under 4.2 but it looks like its even tighter on my clients under 5
05:35
<ogra>
bluedragon, minimal reqs for ltsp5 are 48M
05:35
and thats really minimal i'd rather recommend 64

hi ogra
06:23
i managed to get ldm working somehow, but not properly
06:27
<ogra>
whats missing ?
06:28
<cyberorg>
we got kiwi setup nfsboot
06:28
i put in ldm there
06:28
without all the ltsp scripts, it cant find $SERVER
06:28
so I export manually
06:29
and gtk pixbuf loader is pain
06:29
you are working on ldm without all gtk deps right?
06:32
<ogra>
no
06:32
i'm working on a ldm with 'less' gtk deps ;)
06:32
and written in C instead of python
06:33
<cyberorg>
installing gtk and python-gnome brings in almost half of gnome with it
06:33
<ogra>
yes
06:33
thats why we have split out gnocecanvas in a separate package in ubuntu :)
06:33
ldm only uses gnomecanvas beyond the plain gtk stuff
06:34
but that extensively
06:34
the new one will only need libgtk2.0
06:35
<cyberorg>
when is it due :)
06:36
<ogra>
next ubuntu release (oct)
06:36
its already there in a working form, i'll soon add it to the development code
06:37
<cyberorg>
is it this one? https://code.launchpad.net/~ogra/ltsp/ldm-greeter
06:37
<ogra>
yes
06:37
i'll merge that soon into the main branch
06:37
or we split out ldm's source ... we'll discuss that in sevilla in two weeks
06:38
<cyberorg>
that one is working one so can i test it?
06:38
<ogra>
yep
06:38
check the paths of the pngs in the source ... so you point to the right files
06:38
<cyberorg>
ok
06:39
are gtk paths har coded like in current ldm?
06:39
<ogra>
it produces a binary ... replace the greeter/gtk file with it
06:39
paths will be set by a theme dir and hardcoded image names ...
06:39
themes will be handled through gtkrc files
06:40
(the old ldm had its own theme engine)
06:40
<cyberorg>
doesnt it produce ldm binary?
06:41
<ogra>
no
06:41
its only te greeter
06:41
<cyberorg>
so we still use python ldm
06:41
<ogra>
yes
06:41
<cyberorg>
greeter.c:359: warning: passing argument 2 of ‘g_timeout_add’ from incompatible pointer type
06:41
<ogra>
unless someone comes up with something similar safe and better
06:42
thast only a warning
06:43
you should have a binary you can execute ...
06:43
<cyberorg>
ok, got the greeter
06:43
<ogra>
good
06:44
<cyberorg>
where should i copy that?
06:44
<ogra>
where you copied the greeter/gtk file to
06:44
replace it
06:44
<cyberorg>
cp greeter /opt/ltsp/suse-i386/usr/lib/ltsp/greeters/gtk?
06:44
<ogra>
yes
06:45
<cyberorg>
ok, probably you need -o gtk instead of -o greeter in compile.sh
06:45
<ogra>
and make sure the cient finds the pngs in the chroot at the right place, else it wont start
06:45
nah
06:45
it will be handled by a makefile if i merged it ;)
06:45
thats only for testing and debugging
06:45
i usually run the greeter standalone in my X session while working on it
06:46bobby_C has quit IRC
06:46
<ogra>
its not production ready yet and will surely still take some onths
06:46
*months
06:47
<cyberorg>
another problem is that nfsboot gives a lot of errors if chroot is exported readonly, so have to export rw, system cant write /tmp /var/run cant create sockets etc
06:48
how do we solve that?
06:48
i tried mount -t tmpfs none /tmp and mounted all those bits
06:49
but that is not a good way
06:49
<ogra>
thats the best one atm
06:50
see the bind_mounts function of ltsp-client-setup
06:50
<cyberorg>
mounting / rw has one great advantage, i can tail -f all the logs right off from server
06:50
<ogra>
you need to run it very early during boot
06:50
mounting rw will break as soon as you have more than one client :)
06:51
<cyberorg>
yes true
06:51
<ogra>
they will write different things into different files
06:51
you *must* have the tmpfs munts
06:51
*mounts
06:51Q-FUNK has joined #ltsp
06:51
<ogra>
it depends on your distro *which* files and dirs though
06:51
<cyberorg>
fxrsliberty: exactly that is what we are discussing :)
06:51
<ogra>
you will need to find that out
06:52
<cyberorg>
/tmp /var/tmp and /var/run so far
06:52
<ogra>
/etc/hosts /etc/fstab ... you need to find a proper way to handle mtab
06:52
etc
06:52
there is more :)
06:53
<cyberorg>
can we mount files too?
06:53
tmpfs /etc/fstab ?
06:53
<ogra>
look how the function does it
06:53
<cyberorg>
how does live CD do it?
06:53IRCzito has quit IRC
06:54
<ogra>
it uncompresses the whole root in ram afaik
06:54
at least the ubuntu one i think ... from a squashfs image
06:54
<cyberorg>
isnt there a way that everything is rw, and changes just stays in swap or memory?
06:55
<ogra>
would you really want an rw exported nfs path in a corporate environment ?
06:55
on your server ...
06:55
<cyberorg>
no i mean it can be exported ro, but the client thinks it is rw and can make changes, but they remain in ram only
06:56
<ogra>
yes, thats what we do :)
06:56
<cyberorg>
everything?
06:56
<ogra>
no
06:56
that would raise your RAM reqs immensely
06:56
<cyberorg>
what does unionfs bring?
06:56
<ogra>
only selected files we need to boot up X and ldm
06:56
unionfs just beautifies it
06:57
<cyberorg>
?
06:57
<ogra>
if you type mount on a current TC you get about 30 lines output
06:57
mounting that into a unionfs will only show you /
06:57
technically nothing changes ...
06:57
<cyberorg>
ok
06:58
<ogra>
you system jsut des think it has / and some rw files in it
06:58
<cyberorg>
what is pivot_root stuff in the scripts for?
06:58
(or did it see it somewhere else)
06:58
<ogra>
i think thats from initrd times
06:59
<cyberorg>
yes, i was going through linuxrcs
07:00
another thing is how are local devices handled, if i understand correctly, you have daemon running on server and client sends it a message whenever something is plugged?
07:00
<ogra>
no
07:00
the ltspfs daemon runs on the client
07:01
udev handles the plugging, local mounting and fstab adding ...
07:01
<cyberorg>
so how does all the mounting happen
07:01
that is local, how does it show to users
07:01
<ogra>
you plug in a device ... udev gets a kernel event ... udev adds it to fstab ... and mounts it in /var/run/drives/<device>
07:02
then it connects to the ssh socket ldm has opened for ltspfs
07:02
through that it executes ltspfsmounter on the server
07:03
ltspfsmounter mounts the ltspfs mount from the client to /tmp/.$USER-ltspfs/<devicename>
07:03
then it calls the sudi root binary lbmount to bind mount /tmp/.$USER-ltspfs/<devicename> to /media/$USER/<devicename>
07:03
<cyberorg>
ltspfsmounter is installed on the server and the user can launch it, should be suid, because users cannot mount
07:03
<ogra>
*suid
07:04
<cyberorg>
yeah, figured
07:04
<ogra>
gnomevfs picks up the new device in /media/$USER/<devicename>, creates an icon on the desktop and adds it to the nautilus device list
07:05
the ltspfsmounter stuff, lbmount and all the rest will go away soo ... we'll completely switch to hal
07:05
*soon
07:05tyndyll has left #ltsp
07:05siji has quit IRC
07:05
<cyberorg>
i was thinking about that, and instead of using ltspfs, thought of samba?
07:05
<ogra>
the ssh tunnel is likely go go away as well in favor of an Xatoms implementation
07:06
<cyberorg>
just share it through samba and mount on the server users home
07:06
Xatoms?
07:06
<ogra>
there are various solutions you could use ... ltspfs is simply perfectly tailored for the task, but nothing forbids you to use something like cifs or smb
07:07
<cyberorg>
i am thinking from the lazy admin who doesnt know coding :)
07:07
<ogra>
in any case you would have to write a new implementation :)
07:07
<cyberorg>
we could write some udev rules when devices are plugged to do that
07:07
<ogra>
thats what we do
07:08
you just have to rewrite all the scripts, have a samba server running and configured on the client etc
07:08
i guess yur minimal RAM reqs will be starting ~128M
07:08
<cyberorg>
i understand just 1% of ltsp scripts so far, once i understand them more i might not think about what i understand about other stuff :)
07:09
true, we would want to keep ram requirement low
07:09
so the status so far is i can nfsboot, launch ldm and connect to the server
07:10
next on the agenda should proably swap
07:10
<ogra>
right, but only with an rw root ... fix that first i'd say
07:11
<cyberorg>
also ro, with some tmpfs, but should do it in a proper way, will look up that function
07:13
<ogra>
just copy/paste the bind_mounts function into an initscript and run it ... run that very early in the boot process
07:13
<cyberorg>
btw, the scripts are very well written, even i can understand what they are doing
07:13
<ogra>
:)
07:15
<cyberorg>
first image i created was about 400 MB, after all gtk, python-gnome bits my image is over 1GB :(
07:16
you guys got composite environment running on the clients?
07:16
<ogra>
mine is 380 with all gtk gnome bits
07:16
<cyberorg>
suse deps are massive
07:16
<ogra>
our Xserver drivers have composite on by default
07:17
<cyberorg>
ok, so ltsp clients can do compiz/beryl
07:17
<ogra>
but as long as you dont access these functions they are not used
07:17
*could*
07:17cliebow_ has joined #ltsp
07:17
<cyberorg>
not tried?
07:17
<ogra>
you would to have to run it locally
07:18Avatara has joined #ltsp
07:18tiagovaz has joined #ltsp
07:18
<ogra>
since they need direct access to the HW
07:18Avatara has quit IRC
07:18Avatara has joined #ltsp
07:18
<cyberorg>
but ltsp client X server is running on the hardware locally
07:19
only Xsession is on the server, not sure how we can execute compiz in that session accessing clients X and hardware, hmm
07:26
<ogra>
you cant as i said abov
07:26
e
07:26
you need to run them locally
07:27
<cyberorg>
some german bunch has some thin client implementation that either does that or intend to do it, not suere how

07:54
<ogra>
cyberorg, our fat client implementation will be able to do that, on fat clients everything runs locally
07:55
<cyberorg>
yeah, it would be same as kiwi nfsboot :)
07:56
<ogra>
not really
07:56
unless kiwi runs in RAM
07:59
<cyberorg>
the image we are using is diskless image, running in ram
08:00
sorry, i dont understand, so how does it boot?
08:02
<ogra>
its a thin client setup with a desktop and login manager installed locally
08:02
it works exactly the same as a thin client but runs everything in ram
08:03
<bluedragon>
file system on nfs?
08:03
<ogra>
yes
08:03
a readonly nfs export
08:04
<cyberorg>
and user data?
08:04
<bluedragon>
don't tell me unionfs
08:04
<ogra>
userdata via a /home mount
08:04
thats why we havent implemented it yet
08:05
it requires a decent server setup for mounting /home and authenticating users
08:05
since we only use distro packages in ltsp5 thats quite an amount of changes to essential packages
08:06
<bluedragon>
how so whats your host op
08:07
<ogra>
ubuntu indeed, sine there ltsp5 gets developed :)
08:07
<cyberorg>
:)
08:08
<bluedragon>
yer ubuntu seams to be treating ltsp as just another arch.
08:08
<ogra>
??
08:10
<bluedragon>
what I'm trying to say is that the changes needed to get any distrubtion to run ltsp are just about the same as you would need to do to get that same distro to run on a different arch eg ppc or playstation etc
08:10
bit like live boot, install it or ltsp it
08:13lumberjacklinux has quit IRC
08:14
<ogra>
not exactly, but yes ... there are changes i make to system packages taht wouldnt be there without ltsp ...
08:14
another arch is a way bigger thing :)
08:15* ogra wouldnt want to maintain a complete arch :)
08:15
<ogra>
you could call it a mini-ubuntu-derivative-to-just-run-X-and-ldm :)
08:16
<gvy>
bluedragon, well not exactly indeed
08:16
<bluedragon>
could not thing of a good term.
08:17
But Ltsp is just another way of running ubuntu, like Live Boot is different again
08:17
<ogra>
yep
08:17
they have much in common though
08:17
<bluedragon>
and needs quite a bit of work to get it to work properly.
08:18McDutchie has quit IRC
08:18
<gvy>
i'd rather not compare it to subarch but to a (meta)deployment of a complex app
08:18
<ogra>
huh ? what work do you mean ? sfter setting up the client chroot with ltsp-build-client i can immediately use my TCs here with it
08:18
<bluedragon>
after all it took years to get from just an install disk to the situation we have now with pratically every distro being a live install.
08:18
<gvy>
ogra, no dhcpd/tftpd, eh? :]
08:18
<bluedragon>
and now we have ltsp as well
08:18
<ogra>
gvy, ltsp-server-standalone sets all that up :)
08:19
<gvy>
bluedragon, well there are sane distros still
08:19
not requireing half a terabyte of ram just to dump a slew of packages on the drive(s)
08:19
<ogra>
if you have the iterface your TCs use configured to the right static ip it works our of the box

https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall
08:19
<gvy>
s/rei/ri/
08:20
<bluedragon>
you don't nned to live boot ubuntu to install ubuntu :) and somtimes it does not work anyway
08:20
<gvy>
ogra, read around -- IRL there are less trivial situations usually ;)
08:21
<bluedragon>
right has this ltsp 5 install worked or is it going to tell me whats wrong....
08:21
<gvy>
well covering and generalizing trivial ones is a big deal indeed anyways...
08:21
<bluedragon>
nope "could not load modules.dep no such file"
08:21
<ogra>
gvy, i'm pretty sure the majority of users will be covered
08:22
<bluedragon>
well its nice and simple I'll give you that one and once the few bugs have been removed it will be wonderul.
08:22
<ogra>
in case you want to have 7ltsp servers in parallel with 3 different subnets and centralized ldap for auth, i'd assume you know how to do the trickier tasks
08:22
<bluedragon>
few nots like must be running 7.04 for etherboot to work would help.
08:23
<ogra>
te point is that you *can* have a running ltsp setup within 10 minutes and without any further configuration
08:24
<bluedragon>
well yes if your lucky I'm not
08:24
currently I'm clocking more like 2 days
08:24
and still have not sucseeded.
08:25
<ogra>
on what distro ?
08:25
<bluedragon>
ubuntu 7.04
08:25
<ogra>
and you followed the howto ?
08:26
<bluedragon>
as I said last error on boot read
08:26
<ogra>
and have no ltsp4.2 bits anywhere or something ?
08:26
<bluedragon>
could not load modules.dep no such file
08:26
yes on another machine
08:26Q-FUNK has quit IRC
08:27
<bluedragon>
and a cross fired dhcp setting somthing for one client while I test
08:27
<ogra>
so i assume you have a dhcp server running anywhere already
08:27Q-FUNK has joined #ltsp
08:28
<ogra>
can <ou boot without the splash screen and check if the nfsmount works properly ?
08:28
and where it tries to mount from ?
08:28
(its pretty informative if you drop quiet and splash from the bootoptions)
08:28
<bluedragon>
I have one dhcp server and the one client that is meant to be running ltsp 5 dhcp says next-server 192.168.0.33;
08:29
<ogra>
please check without bootsplash ...
08:29
it should show you the rootserver IP it thinks it should use ... as well as the rootpath ...
08:29
<bluedragon>
hmm yes I know i'm using etherboot and I've already worked that one out.
08:30
yes and thats correct from what I can see.
08:30
<ogra>
there must be other errors ...
08:31
your ltsp-build-client finished with a success message ?
08:31
and you didnt fiddle with any stuff ?
08:31
<bluedragon>
yes
08:31
nope
08:32
<ogra>
etherboot works out of the box for others so i'm a bit surprised it doesnt for you
08:32
<bluedragon>
etherboot works fine it boots
08:32
mouts the nfs
08:33
<ogra>
well, if you dont find modules.dep you are booting a wrng kernel or mount a wrong nfsroot
08:33
<bluedragon>
then moans about date stamps on a load of files being in the future
08:33
then crashes saying can't find modules.dep
08:33
hmm might have somthing to do with trying with 6.04 first then right. I'll check the kernel
08:34
<ogra>
well, ....
08:34
so you fiddled around with it
08:34
if its not booting the nbi.img file ltsp-build-client created for you
08:36
erm didnt you say before your clients only have 24M ?
08:41
<bluedragon>
yes but...
08:41
<ogra>
no
08:41
no way to boot that at all
08:41
<bluedragon>
hmm the right kernel gets it much further.
08:41
<ogra>
the kernel and initramfs need 36M to *load* ...
08:41
it wont be able to start X if it even gets that far
08:41
<bluedragon>
Its got as far as mouting the swap now I've got the kernel right
08:42
<ogra>
hmm, good luck :)
08:42cule has joined #ltsp
08:42
<ogra>
i havent anything gotten to boot below 42M ...
08:43
even with nbd swap enabled
08:43
<bluedragon>
well its booted.
08:43
<ogra>
wow !
08:44
try to log in then :)
08:44
<bluedragon>
its trying to start X I believe but I've not got anything set up
08:44
the screen keps flashing currently
08:44
<ogra>
it should run ldm by default
08:44
yeah, no space
08:44
you could try with XDMCP and disable sounds nd localdev in lts.conf
08:45
sound should gain you 2M ... localdev about 3
08:45
<bluedragon>
I was about to do that I end up doing that for somthing simular in 4.2 currently anyhow
08:46
<ogra>
do you see the X on the screen or does it die before ?
08:46
<bluedragon>
flashes black then returns to text
08:47
might be x server settings
08:47marek82 has quit IRC
08:47psyco-ob1wan has quit IRC
08:47
<ogra>
hmm, then it cant start the X server ... seeing the X would indicate it gets beyond that and dies on ldm
08:47
your chances are not good then ...
08:47psyco-obiwan has joined #ltsp
08:48
<ogra>
try to set a higher default swapzise in /usr/sbin/nbdswapd on the server that might help
08:48
<bluedragon>
I don't know my 4.2 clients need XSERVER = nsc so I'll try that
08:49
<ogra>
if they are all the same HW i'd suggest a static xorg.conf ... should gain you some extra mem
08:50
<bluedragon>
intresting point
08:50
<ogra>
if there is a static file, the prober wont run ...
08:51
so it wont allocate ram ;)
08:51
<cliebow_>
bluedragon, what clients are these anyway?
08:52

fully armed 286s ? :)

bluedragon, ogra, we've been doing well with 32M
09:05
but that's altlinux, it's -Wl,--as-needed
09:05
<ogra>
gvy, with ltsp5 ?
09:06bobby_C has joined #ltsp
09:06
<ogra>
ltsp5 uses the distro packages so the distro kernel as well ...
09:06
<gvy>
ogra, with homegrown TS and ltsp4.2
09:07
<ogra>
right
09:07
<gvy>
ogra, homegrown was using distro kernel
09:07
w/o any customizations
09:07
and distro xorg as well
09:07
<ogra>
2.6 series with udev etc ?
09:07
<gvy>
w/o udev, it was ca. 2.6.12
09:07
<ogra>
nice
09:08
<gvy>
actually `free` hinted at 24M
09:08
cache and kernel mem excluded
09:08
<ogra>
so make that work with ltsp5 :)
09:08

hey luiz
13:06
doing great. although it's raining pretty seriously here today
13:06
<pscheie>
hey jammcq
13:07
in 4.2, if I connect a scanner to a client, do all clients have access to the scanner?
13:07
<jammcq>
yeah
13:07
<Guaraldo>
jammcq: Here is raining slowly since late nite yesterday...
13:08
<jammcq>
pscheie: it just becomes a network scanner
13:08
<pscheie>
good, that's what I want: I want it to not matter which client has the scanner
13:08
right, network scanner
13:08
<jammcq>
I have a customer doing lots of scanning
13:08
<pscheie>
so, one kid puts a picture on the scanner, and all the kids can grab the image, right?
13:09
<jammcq>
that would be the slow way
13:09
why would you want each kid to re-scan it
13:09
<pscheie>
I wouldn't, I just thought they'd get whatever the scanner was putting out.
13:10
How do it handle contention then?
13:10
first come first serve?
13:10
<jammcq>
no, it's not like the scanner broadcasts it's output
13:10
you need an application that knows how to talk to the scanner
13:10
<pscheie>
the wiki says OOo and gimp both work with it
13:11
<jammcq>
I have a couple of different scanners. a card-scanner which scans things like insurance cards
13:11
and a full page auto-feed scanner
13:12
the full page scanner is pretty cool. I have a program that senses insertion of the document and automatically scans it in, and then uses some ocr software to find an ID number so I can match it up with the patient
13:13
<pscheie>
the teacher has just a flatbed scanner, I think, perhaps two of them
13:13
<jammcq>
make sure the scanner is supported by sane
13:14
<pscheie>
most are these days, aren't they?
13:14
<jammcq>
you wish
13:14
<pscheie>
I've got 2 or 3 at home, but they're all HP
13:14
<jammcq>
you'd be surprised how hard it is to buy a scanner that you can be certain is supported
13:14
*some* hp scanners are supported
13:14
<pscheie>
does usb vs. scsi matter?

I've never tried mine with a terminal, just on the server or fat client

I have a question not directly related to ltsp but I hope someone can help. I have a dhcp server which has been working fine and a client boot disk which has also worked fine but now the client keeps getting assigned the IP of the server even though the server tries to give it another IP and the IP of the server isn't even in a pool.

That may be the case here too but I dont remember the password I set up to check that it's disabled. I unplugged it from the network and got the correct IP assigned but now the samba mount is failing where before it worked when I assigned a static IP.

Now it's working. Took a reboot.
