hi all
01:47
i have download ubuntu 8.04 server edition
01:47
now am going to make it my kubuntu ltsp server
01:48
any one works on ubuntu 8.04 server with kubutu desktop as lTSP image
01:48
hows LTSP in 8.04

<MasterOne>
Has something drastically changed concerning LTSP between Ubuntu Gutsy & Hardy? Is it still not possible, to resume a session?
02:15
I really would like to use LTSP on Ubuntu, but there were/are two showblockers for me: 1. Unability to leave the user session running once client logs off & to resume that session on next logon. 2. No mechanism to prevent a user to logon more than once at the same time (messes up the user session).
02:27toscalix has joined #ltsp

<stgraber>
MasterOne: Those two features are still missing, Hardy is a LTS so the goal was to make it rock solid.
02:37
<Nubae>
have u tried 1. with screen
02:37
might work to allow sessions to run while user is off
02:37
<stgraber>
Nubae: screen works for console app, it doesn't with X software (as the X connection is broken when detaching)
02:38
<MasterOne>
stgraber: thanks, too bad, then I have to go for a VNC setup instead
02:39
<Nubae>
yeah figured, but he doesn't mention what kinda app he wants to have running when session is logged out :-)
02:44
I need to uninstall firefox 3 completely and make firefox 2 default...
02:44
how do I uninstall firefox 3 beta?
02:44MasterOne has quit IRC
02:45nantes_geek has joined #ltsp
02:45
<Nubae>
never mind...
02:49
anyway, looks like its definetly firefox 3 that was causing problems
02:49
I moved back to using 2 and now no more system freezes
02:52bobby_C has joined #ltsp
02:52
<Nubae>
ah damn... doing sudo apt-get remove firefox only removed it for my user
02:52
I need to remove it for all users

04:27
<laga>
Nubae: report a bug against firefox? it's still beta
04:27
<Nubae>
a bug that says what? I'm not sure what the cause of the issue was, just that its fixed by reverting back to firefox 2
04:28
<laga>
just report the issue then and work with the developers to find out the issue :)
04:28
the cause*
04:29
<Nubae>
ok, like that, yeah I'll try that

Nubae, use italc, not tcm
04:44
<Nubae>
ok, sudo apt-get install italc?
04:45
<ogra>
italc-master
04:45
the client already runs in all edubuntu sessions
04:45
<Nubae>
righto... did u see my comments on firefox 3 beta 5... it WAS the culprit after all
04:46
but could be flash plugin or pulse sound, who knows
04:46
mplayer plugin or acroread plugin
04:46
have lots of stuff installed, so tracing the cause is gonna be difficult
04:48
I get a 'there seems to be no italc service running on this computer'
04:50
<stgraber>
is that on a thin client ?
04:51
education-thin-client-server or edubuntu-desktop install italc-client so your client should have it running
04:54
<Nubae>
ok, it says its already installed
04:55
and also: italc-client set to manually installed.

setting a user to use /bin/false as their shell doesn't work?
05:14
<laga>
Nubae: i thought you were using low-fat clients?
05:14
<Nubae>
not only
05:14
some are low fat
05:15
just the high end multimedia laptops are set to use low fat

stgraber, eeek, education-thin-client-server is debian edu ... dont recommend it, i dont know what it changes
05:50
<stgraber>
ogra: well, I just did a rdepends on italc-client
05:50sepski has quit IRC
05:51
<ogra>
stgraber, well ... there are pretty harmful debian-edu packages with lots of cfengine scripts inside that mangle your config
05:51
Nubae, what do you want to achieve with /bin/false as shell ?
05:52
<stgraber>
ogra: looks scary
05:53
<ogra>
they are working on it, but didnt weed out everything yet so i usually tel people to stay away from debian edu packages in ubuntu

ogra: I'm trying to disable shell access for certain users
06:27
these users are problem users who know how to create ssh tunnels to bypass the content filters, etc
06:27
<ogra>
right, but switchng the shell to /bin/false only diasbles their login
06:27
indeed
06:31
<Nubae>
ah I thought it would disable their shell
06:31
<ogra>
it does
06:32
<Nubae>
completely, get it
06:32
<ogra>
so after login /bin/flase is executed instead
06:32
which just returns false and exits
06:32
<Nubae>
so, is there a way to do what I want?
06:32
<ogra>
pessulus
06:34
<Nubae>
but then it needs to be defined for everyone right?
06:36
or is there a way to batch process that
06:36jammcq has quit IRC

warren, whats that 755 vs 750 change you did ? thats nonsense
07:24
(in ltspfs)
07:25
once mounted use will even refuse access to root for that dir, only the owner is allowed to look inside
07:26
<Nubae>
ogra: I don't get pessulus, the documentation says it integrates with users, but when I go and try and edit any user from the system I can't edit anything

warren, i'm not really happy with that hackish workaround david merged now ... it seems a lot more messy than just using access() wrapped in a timeout and doesnt fix that actual problem at all (only adds special casing to ltspfs)
08:12* ogra doesnt see where relying on a certain amount of layers in the directory tree is any saner than having an access() call

<warren>
ogra: I think it can be improved
09:04
<ogra>
warren, well, it doesnt fix th ebug at all
09:05
<warren>
ogra: mclasen and davidz were especially concerned about safety
09:05
do you know how to do access() with a timeout without using fork?
09:05
<ogra>
(if yu plug in a usb key and switch user, the new user will have th ekey on the desktop without being able to access it or unmount it)
09:06
<warren>
huh?
09:06
<ogra>
warren, i wonder if open() could help here
09:06
<warren>
If you have a suggestion for a better implementation then please suggest patches.
09:06
<ogra>
i think it sits on a bit higher layer
09:06
i'm digging
09:07
its good that it is worked around for ltspfs
09:07
but the actual bug doesnt get fixed
09:08
one option would be to check what fs it is and dont do access on known blockers for example
09:08
but run the access() on all known local mounts
09:08
<warren>
"check what fs it is" is not a trivial thing
09:08
<ogra>
(and ltspfs)
09:09
<warren>
"check if local or network" is wanted by many other things but we've failed to write something reliable
09:09
it is true that we need a non-blocking access() equivalent
09:09
<ogra>
well, an app responsible for mounting devices should know about filesystems
09:09
<warren>
<ogra> (if yu plug in a usb key and switch user, the new user will have th ekey on the desktop without being able to access it or unmount it)
09:09
are you talking about plugging USB key into the server?
09:09
<ogra>
thats the original bug, yes
09:09
no
09:10
totally not ltsp related
09:10
the bug is that the system needs to hide inaccessible mounts
09:10
<warren>
Some people might WANT this current behavior
09:10
<ogra>
no matter if they are ltspfs or not
09:10
<warren>
a teacher can make available files to all students
09:10
just pop-up
09:10
<ogra>
warren, i have been bitten often enough by it when holding talks before we had the fix
09:11
<warren>
If I plug a USB stick into my server, it pops up both locally and on my clients
09:11
read-only on the clients
09:11
<ogra>
read only but you have read access
09:12
<warren>
This is clearly different than the ltspfs case
09:12
ltspfs case gives no read access to other users

warren, http://launchpadlibrarian.net/14014898/nautilus.debdiff btw ... in case you want to suppress mount options in nautilus (not really for upstream)

s/mount/umount/
09:15
<warren>
ogra: nah, I found a way to implement true unmount
09:15
ogra: so it will work from the menu
09:15
<ogra>
eek
09:15viking-ice has joined #ltsp
09:15
<ogra>
and that doesnt break ltspfs internally ?
09:15
<warren>
ogra: it will retain the current robust behavior of handling unplug
09:15toscalix has quit IRC
09:15
<warren>
ogra: I'm going to try to send the unplug event to ltspfsd
09:16
<ogra>
well, the device is never mounted unless yu read or write
09:16
so you do a fake unmount ?
09:16
<warren>
or "stop trying to mount" event
09:16
<ogra>
thats totally breaking the cool purpose of ltspfs
09:16
you could use autofs then
09:16
<warren>
ogra: I'm not taking anything away from ltspfs
09:16
<ogra>
well, you add incosistency between distros
09:17
<warren>
I'm only making the Delete button and Unmount work, because it would be a bad thing to train users to expect they can just pull things on Linux.
09:17
If you move between a thin client and a real Linux desktop?
09:17
<ogra>
right thats why we hide these options completely
09:17
as long as you are on a TC
09:17
<warren>
It is highly inconsistent that they need to do it one way with a Linux desktop and another with a thin client.
09:18
<ogra>
right, it should be done the same way as in ltspfs everywhere
09:18
<warren>
but GNOME desktop will never do it that way
09:18
<ogra>
but i didnt manage to convince the world yet :P
09:18
you mean t will even force users to unmount if that isnt needed anymore because the kernel cares fo4r such stuff ? i doubt that
09:20
(be careful with *never* :) )
09:20Guaraldo has joined #ltsp
09:20Guaraldo has left #ltsp
09:20
<warren>
no force
09:20
it will ALLOW users to unmount from the menu
09:20
the current behavior will also work fine
09:21
<ogra>
warren, anyway, switching to proper hal/dbus handling fr ltspfs should solve all issues
09:21
as soon as the session can communicate with te real HW it will solve itself
09:21
i'D rather go that path than adding more and more complexity around ltspfs
09:22
sadly everyone wastes more and more time into ltspfs workarounds instead of fixing the root cause (me included)
09:23
<laga>
ogra: who do i bug about merging my changes? you or someone else?
09:23
<ogra>
with proper hal integration we could just leave everything to gvfs
09:23
laga, for intrepid ?
09:24
<laga>
ogra: into ltsp upstream
09:24
<ogra>
we need to discuss some stuff
09:24
but i'm still hogged by classmate this week
09:24
<laga>
no problem, i'm still busy with other stuff as well

ogra: can the hal/dbus approach be tunneled?
09:36
<ogra>
tunneled ?
09:37
<Gadi>
or be client server in the correct direction?
09:37
<ogra>
Gadi, it needs to attach to the ssh tunnel for communication
09:37
<Gadi>
ie can the connection be made from thin client to server
09:37
ok
09:37
good
09:37
<ogra>
and we'll likely need a fake hal or so on the session side that just directly forwards from the TC
09:37* Gadi is working towards localdev support across NAT
09:38
<ogra>
ah
09:38
well, as long a yu got the ssh socket al should be fine
09:38
<Gadi>
so, I will likely tunnel the ltspfs conenction
09:38
<ogra>
no
09:38
<warren>
Gadi: I understand that some people are using NAT, but it isn't a throughput issue for them?
09:38
<Gadi>
I just worry that dbus would be one more thing to tunnel
09:38
<ogra>
my approach would use hal/gvfs
09:38
only ltspfs in the backend for transport
09:38
as we use it now
09:38
<Gadi>
good
09:38* Gadi is a dbus/hal novice
09:39* Gadi needs to learn
09:39
<ogra>
(which currently isnt tunneled)
09:39
<Gadi>
warren: nobody uses NAT for ltspfs yet afaik
09:39
<ogra>
the infrastructure is all there its just that nobody adjusted it in the way we would need yet
09:39
<warren>
ltspfs isn't even the greatest cause of bandwidth usage
09:39
not even close
09:39
<ogra>
its plain fuse
09:40
<Gadi>
right - so no throughput concerns here :)
09:40
<ogra>
no compression or anything
09:40* Gadi wants my USB pen drive to work when I connect to the Linux app server a few subnets away
09:40
<ogra>
you could surely add nifty little features if needed ;)
09:40
<Gadi>
without having to setup symmetrical routing
09:40
thats what I will hack on :)
09:40
no worries
09:41
<ogra>
drop ltspfs and re implement with sftp/scp ;)
09:41
then you can use the tunnel directly
09:41Guaraldo has quit IRC
09:42
<ogra>
i had some code that did xwd dumps for screenshots stored on the clients for some test i did
09:42
that direcly used scp from an rc.d script
09:42
<Gadi>
well, if you would split out the ltspfs automounter, I m=would consider it
09:42
:)
09:42Guaraldo has joined #ltsp
09:42
<ogra>
you mean the two scripts and the udev rules ? cmon ...
09:43
<Gadi>
and the daemon to manage it
09:45
<ogra>
what for ?
09:45
if you want scp or sftp you dont need a daemon
09:45
just attach to the existing tunnel with the sftp
09:45
directly from add_fstab_entry
09:46
<Gadi>
no, if you want the automounter to be in an unmounted steady state you do
09:46
<ogra>
you have a udevd running already ;)
09:46
right, that requires ltspfs
09:46
<Gadi>
there ya go
09:46
:)
09:46
and, the merry-go-round returns to the point of entry
09:46

<hpa> warren: My opinion about coreboot is that it would be a massive benefit to the world if they collectively committed seppuku.
12:24
<ogra>
heh
12:24
<johnny>
hmm.... why?
12:24
<warren>
This doesn't bode well for getting coreboot/Etherboot to work with wraplinux.
12:25
He doesn't care about coreboot support
12:25
<johnny>
cuz of syslinux ?
12:25
<warren>
He thinks the design of coreboot is stupid
12:25
<johnny>
did he write wraplinux too?
12:25
<warren>
yes
12:25
wraplinux is similar to mkelfImage
12:26
I'll continue trying to get this work, but this doesn't bode well for the future of coreboot/Etherboot.
12:27
mknbi, mkelf, mkelfImage and wraplinux all fail currently with the client Q-FUNK sent me.
12:29
<Q-FUNK>
mknbi and mkelf will definitely fail. they use bios calls.
12:29
mkelfimage is the only one that would work.
12:29Pascal_1 has quit IRC
12:30
<warren>
mkelfimage did get the closest to working
12:30
it actually loaded the kernel on your DBE61C
12:30
but the initrd decompression failed
12:34
<ogra>
Q-FUNK, didnt you have to fiddle with the Makefile for the debian/ubuntu build ? was that anything that could cause it to break for warren in the default conifg ?
12:34
<warren>
<hpa> warren: wraplinux' own BIOS calls are reasonably easy to bypass
12:34
<hpa> warren: However, Linux itself uses BIOS calls to probe memory, etc.
12:34
<hpa> warren: In fact, wraplinux only uses a subset of the BIOS calls used by Linux itself.
12:34
<Q-FUNK>
ogra: I had to overhaul their whole autoconf usage
12:34* ogra sees "Required an ugly patch to Makefile.conf.in that really points
12:34
<ogra>
to a sloppy upstream autoconf implementation."
12:34
in the changelog
12:35
<Q-FUNK>
that one
12:35
<warren>
Q-FUNK: hpa is pointing out that wraplinux using BIOS calls is only a subset of BIOS calls that Linux itself needs.
12:35
<ogra>
right, i doubt warren has these adjustments in his package
12:35
<Q-FUNK>
however, the code has been taken over by the coreboot guy. now is a very good time to submit patches to the autoconf implementation
12:35
<warren>
ogra: which package?
12:35
<ogra>
warren, mkelfimage
12:36
<warren>
I'm willing to try it
12:36
<Q-FUNK>
basically, the previous upstream shipped a VERY (underline, VERY) sloppy tarball.
12:36
<warren>
ogra: how do I download your package source?
12:36
<Q-FUNK>
coreboot guys imported that code into their SVN before the previous upstream's ftp site vanished into thin air.
12:37
<ogra>
warren, https://launchpad.net/ubuntu/+source/mkelfimage
12:37
<johnny>
OT question.. anybody recommend a decent XML editor ?
12:38
<Q-FUNK>
but afaik they never got around fixing the sloppy autotool implementation. in the debian/ubuntu package, I ended up having to run autoconf twice, in debian/rules, to get this to build reasonably well
12:38
warren: or actually, get the latest debian one
12:38nantes_geek has joined #ltsp
12:38
<warren>
* Added -fno-stack-protector to CFLAGS (fixes FTBFS on Ubuntu).
12:38
Required an ugly patch to Makefile.conf.in that really points
12:38
to a sloppy upstream autoconf implementation.
12:38
<Q-FUNK>
http://ftp.debian.org/debian/pool/main/m/mkelfimage/
12:38
<warren>
-fno-stack-protector was needed to make it work?
12:38
<ogra>
yes
12:38
<warren>
ah, that's likely the cause of my breakage
12:38
<ogra>
well
12:39
it failed to build
12:39
yours builds
12:39
(FTBFS == failed to build from source)
12:39
<warren>
<hpa> Linus has said Subversion was the most useless project ever. Coreboot would be an improvement if it was useless; it is in fact causing massive damage to large number of other projects.
12:39
lots of fun quotes from him
12:39
<ogra>
heh
12:40
<Q-FUNK>
it's not like he has been known for his witt.
12:40* ogra looks shocked at https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/224259
12:40* ogra cant headdesk enough ....
12:40
<ogra>
*SIGH*
12:41
how did that happen
12:41
<laga>
yay, SRU for ogra :(
12:41
<warren>
which one is hardy?
12:41
<ogra>
8.04
12:42
bitter
12:42
<Q-FUNK>
warren: the hardy package is outdated. use the debian one
12:42
<ogra>
very very bitter
12:42
<laga>
ogra: just do the SRU and be done with it
12:43
<ogra>
laga, experience tells that users rarely user hardy-updates to build their clients ... and experience tells that users rarely update their chroots
12:43
<laga>
ogra: so hardy-updates isn't enabled by default?
12:43
<ogra>
i will drown in printing bug duplicates
12:43
laga, the client only enables whats needed by debootstrap
12:43
<laga>
you should also enable hardy-updates then.
12:43
<ogra>
hmm
12:44
that breaks on the CD builds
12:44
so these will need specisl casig as well
12:44
*special casing
12:44
<laga>
--no-updates ;)
12:45
<ogra>
yeah, but thats getting quite big for an sru
12:45
and i cant explain how that happned
12:45
<warren>
Q-FUNK: hardy one != coreboot svn?
12:45
<ogra>
i use the ltsp-client-core.install file from gutsy, i'm pretty sure with that
12:45
<laga>
ogra: you're part of upstream ;)
12:46
<Q-FUNK>
warren: indeed not
12:46
<ogra>
laga, i wont pull anything from upstream for an sru
12:46
that needs to be fixed in the package
12:46
<warren>
oh gah, coreboot's import is only 2.7
12:46
nothing more
12:47
<Q-FUNK>
aye, but then you're already missing the build wizardry I did in debian
12:47
<warren>
-fno-stack-protector broke the build or wrapped ELF images?
12:47
+DEFS=-DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1
12:48
<Q-FUNK>
it works on hardy
12:48
looks at my changelog
12:48
<warren>
how do I find the changelog?
12:48* ogra smiles about LP already listing intrepid
12:48
<ogra>
warren, look at lp
12:48
its identical
12:49
we just rebuilt it twice in ubuntu and added packaging changes
12:49K_O-Gnom has joined #ltsp
12:49
<Q-FUNK>
warren: alpply the debian diff over the upstream tarball
12:49
<warren>
LP doesn't have -5
12:49
<ogra>
oh, -5
12:50
right, we didt start the intrpid import yet :)
12:50
<warren>
Q-FUNK: any idea what the hex blob change in mkelfimage-2.7/linux-i386/convert.bin.c does?
12:50
<ogra>
toolchain is just being built
12:50
<Q-FUNK>
warren: IIRC it's some ELF header
12:52
<warren>
Q-FUNK: where can I find the changelog entries from -1 to -5?
12:52
<Q-FUNK>
in the debian folder
12:53
might be a good idea for you to get familiar with the basics of debian packaing, so that you can extract usefull changes from debian/ubuntu
12:53
<warren>
http://ftp.debian.org/debian/pool/main/m/mkelfimage/ ? which file?
12:53
<Q-FUNK>
in the debian diff
12:53* warren points out that "making available" is not good enough for an upstream ecosystem
12:53
<Q-FUNK>
do as I told you above: unpack the debian diff on top of the tarball
12:54
neither is "making an RPM". now are you gonna unpack the tarball or expect everyone to chew your own meal?
12:54
<warren>
+ This should allow us to host i386 LTSP chroots on an amd64 server.
12:54
+ Please test this and report any problem to the Debian BTS.

12:56
<warren>
Q-FUNK: do you know which revision the hex blob was introduced?
12:56
<Q-FUNK>
nope
12:56
<warren>
Q-FUNK: I was starting at the giant patch from the beginning, I was trying to understand each part of the diff
12:57
<Q-FUNK>
mc might help. the debian port can do a split view of a debian diff
12:57nantes_geek has quit IRC
12:57
<kikin>
vagrantc: me marca un error
12:59
<Q-FUNK>
warren: put it this way: mkelfimage barely builds. just about. it would need a major overhaul to become portable enough to replace the old mknbi.
12:59
the only good side is that it uses zero traditonal bios call, by default, which is why is succeeds at producing boot images for coreboot.
13:00
mknbi and mkelf cannot be used, because they use several traditional bios services.
13:01
<warren>
Q-FUNK: I guess I wont know what changelog entries match up with which changes, I'll just build it and see if it works...
13:01
<Q-FUNK>
chekc all the file in the debian folder. they might give you a few hints on how to manage to build it cleanly
13:02
i'll admit this much: getting this to build at all was a nightmare.
13:02
<warren>
we added a one liner patch to make it build in fedora
13:02
<ogra>
yay, warren learns debian packaging :)
13:02
<warren>
which might have not been good enough to make it work =)

warren: by doing autoconf twice, then building with -fno-stack-protector

<warren>
it is also somehow putting down its own spec file
13:19
I don't know where that's coming from
13:19

the upstream tarball
13:19
it coes with a spec file

que bueno navegator
14:56
un fabor
14:56
grandote
14:56
puedes ayudarme
14:56
instale desde el CD ubuntu Harly el LTSP
14:56
<Navegator>
Pues depende, yo tambien soy un poco nuevo con el ltsp
14:57
y?
14:57
<kikin>
hasta ahi voy ya intale todo
14:57
pero lei que se debe de configurar
14:57
unos archivos
14:57
es cierto
14:57
o asi puede arrancar los clientes
14:57
<Navegator>
eso es correcto
14:58
<kikin>
mi prema es que archivos debo de configurar y como los configuro
14:58
<Navegator>
primero debes de configurar tu dhcp.conf
14:58
despues correr el build-clients que viene con el ltsp
14:58generic has quit IRC
14:58
<kikin>
el que se encuentra en /etc/dhcp3
14:58
<Navegator>
asi es
14:59
<kikin>
COmo se configura ese archivo el dhcp
14:59
<laga>
if you have /etc/ltsp/dhcp3.conf, it'll take precedence over /etc/dhcp/
14:59
<vagrantc>
kikin: copia /usr/share/doc/ltsp-server/examples/dhcpd.conf at /etc/ltsp/
15:00
kikin: o instala ltsp-server-standalone
15:00
<kikin>
ya lo instale
15:00
el ltsp-server-standalone
15:00
<vagrantc>
/etltsp/dhcpd.conf ?
15:00
<kikin>
entonces copio el archivo
15:00
?
15:00
<vagrantc>
er, /etc/ltsp/dhcpd.conf ?
15:00
<Navegator>
Pues si
15:01
ese esta comentado para indicarte mas o menos como es que debes de configurarlo

si te fijas tambien en ese directorio vas a tener un archivo que se llama ltsp-build-client.conf
15:03
<kikin>
si
15:04
<Navegator>
para mayor documentacion en como ponerlo a punto cuanto lo desees http://www.ltsp.org, http://wiki.debian.org/LTSP/Howto
15:05
a ver configuraciones que debes de hacer:
15:05
1.- el /etc/exports
15:05
hay que agregar:
15:06
/opt/ltsp *(ro,no_root_squash,no_subtree_check)

no
15:06
you don't need that on ubuntu hardy.
15:06
<Navegator>
luego reiniciar el el sistema de nfsd:
15:06
<laga>
everything is done by nbdrootd in /etc/inetd.conf
15:07
<kikin>
ok
15:07
<Navegator>
Ahhhh, that is because I'm using nfs, and debian
15:07
<kikin>
paso 1 concluido
15:08
<Navegator>
para reiniciar el nfs, si vas a utilizarlo le das: /etc/init.d/nfs-kernel-server restart
15:09
en el el dhcpd.conf:
15:09
get-lease-hostnames true;
15:09
next-server 192.168.1.1;
15:09
option root-path "192.168.1.1:/opt/ltsp/i386";
15:10
teniendo en mente que mi servidor tiene como direccion la 192.168.1.1

tienes que checar que en tu servidor sea asi, en caso de que no, pues tendrias que cambiar la linea que te indique por los valores que tu necesites
15:11
<vagrantc>
no necesita root-path con ubuntu

Navegator: is the local hdd ntfs?
15:19

aha.. good question from gadi :)
15:19

15:19
<Navegator>
Gadi: yes it is
15:20
<vagrantc>
ah.
15:20
<Gadi>
MODULE_01 = ntffs
15:20
<vagrantc>
that probably requires more work.
15:20
<Gadi>
er ntfs
15:20
in lts.conf

Navegator: ok. lenny's in pretty good shape. a few more packages from unstable with some nice features (like LDM in ~ 13 langauges) still waiting to get in.
15:28
<Navegator>
vagrantc: I'm using ldm
15:30mccann has quit IRC
15:31
<Gadi>
Navegator: try MODULE_01 = ntfs in your lts.conf
15:31
that *should* give you read-only access to the drive
15:31* Gadi thinks
15:32
<Gadi>
if you have that "removable" line in your udev rules, you will need to remove that as well and reroll the image
15:32
<Navegator>
after making the changes I still seeing only the floppy in the /media/user/ directory
15:32
<Gadi>
when you log in on the thin client console, do: grep ntfs /proc/filesystems
15:32
to make sure ntfs is loaded
15:33
also, do: grep removable /etc/udev/rules.d/*ltsp*
15:33
to make sure the changes you made took effect
15:33
(sometimes I find you have to kill the nbd-server on the server side to get it to export the new image)

15:35
jejeje
15:35
<Gadi>
hmm... come to think of it, the module loading may happen too late
15:35
Navegator: do this: echo "ntfs" >/opt/ltsp/i386/etc/modules
15:35
and then reroll the image
15:36
er, echo "ntfs" >> /opt/ltsp/i386/etc/modules
15:36
:)
15:36
you know what I mean
15:41
<Navegator>
making the changes
15:42
you need to reroll the image, only for the ndb-server, with the hfs is no necesary
15:44
<vagrantc>
Gadi: debian doesn't yet use NBD ... so no need to re-roll the image :)

set SCREEN_07=ldm and SCREEN_08=shell on debian ...
15:55
then ctrl-alt-f8
16:02
<Navegator>
Gadi, vagrantc: it is working!!!!! :-)
16:03
I'll post the changes that was made in a moment
16:05
1.- added ntfs in /opt/ltsp/i386/etc/modules, as you told me
16:06
2.- in opt/ltsp/i386/etc/udev/rules.d/udev.rules
16:06milesd has joined #ltsp
16:07
<Navegator>
added SUBSYSTEMS=="ide", KERNEL=="hd[a-z]", NAME="%k", OPTIONS+="all_partitions" after #workaround for devices which do not report media changes
16:08
3.- in -opt/ltsp/i386/etc/udev/rules.d/z60_ltspfsd.rules added
16:08
ACTION=="add", SUBSYSTEM=="block", RUN+="add_fstab_entry %k"
16:09
and that's it
16:09
Thanks a lot for your help
16:09

kikin: entra a esta pagina, a lo mejor te ayuda mejor por que esta es especifica para el ubuntu: https://help.ubuntu.com/community/UbuntuLTSP

<Gadi>
not sure why you would need to coax udev into recognizing the hard drive
16:10
<kikin>
Navegator: ya configure el archivo COnfig
16:12
<Navegator>
Gadi: its because, I have thin clients that have HD and the people the use them wants access to it
16:13
<Gadi>
right - I dont understand why you had to edit #2
16:13
do not debian workstations recognize hard drives?
16:13
<Navegator>
when you make the change in the udev you force that on the client the ltspfs_fstab is written like you need it
16:14
<Gadi>
that is #3
16:14
in #3, you tell udev to see any block device
16:15
<kikin>
Navegator: regreso en 30 minutos
16:15
<Gadi>
in #2, you tell udev to register the ide hdd as a block device
16:15
do debina workstations not already register ide hdds as block devices?
16:15
this is my quandary
16:16
in either case, I am happy that it works
16:16
<Navegator>
Thanks a lot
16:16
:-)
16:16
<Gadi>
just curious as to why #2 was necessary

lo siento :) :)
16:18* Gadi runs and hides
16:19
<Navegator>
Gadi: I have another question, I use LDM to loggin, but if I put a worng password, the client stop responding, do you know why?
16:19
<sutula>
Gadi: (to pull you out of hiding), I wasn't following along, but if you need an experiment on a Debian workstation, I can do it
16:19
(just holler)
16:20
<Navegator>
or if there is a way to put a time out when a wrong password is entered?
16:20
<Gadi>
sutula: thx
16:20
Navegator: does it not reset the login?
16:20
<Navegator>
Gadi: nop
16:20
<Gadi>
or is the client just so slow that it takes a while?
16:21
Navegator: is this a recent version?
16:21
<Navegator>
Gadi: no, after a while the graphical enviroment shuts down
16:22
Gadi: yes it is the lastest
16:23
<Gadi>
Navegator: perhaps you can look in /var/log/ldm.log on the client (ctrl-alt-f8) when that happens and see where it's getting stuck
16:23
then, we can blame vagrantc in good conscience :)
16:23
<Navegator>
jajajajajajajajajaja :-)
16:24* Gadi had rewritten ldm to not reset X on things like bad password, but I am too sloppy in my contributions so it was hard to merge
16:24
<Gadi>
:)
16:24
so, mainstream ldm still resets X on such things
16:25
its on my todo to be neater
16:25
but, it requires a lot of energy for a personality such as mine
16:25
:)
16:29
<Navegator>
Gadi: jejejeje, I'll wait
16:30
Gadi: the last line in the ldm.log is ssh_chat ------------- Sending pw, and it stop there

16:35
<Gadi>
Navegator: when you get back, try going to the client console (ctrl-alt-f8) and ssh to the server from there with the wrong password
16:35
see if it hangs
16:36
that will tell you if it is an ldm thing or an sshd thing

17:28
<Gadi>
Try setting NumberPasswordPrompts 1 in /opt/ltsp/i386/etc/ssh/ssh_config
17:38
<Navegator>
Gadi: Ok, trying it, what those this line do?
17:39
<johnny>
guess.. ..
17:40
<Gadi>
it tells the client to bail out after 1 password prompt
17:41
I am hopeful we can sweep your problem under the rug :)
17:41
so-to-speak
17:41
and sorry it should be:
17:41
NumberOfPasswordPrompts 1
17:42
close doesn't seem to count with computers very often ;)
17:47
<Navegator>
yeap, the computer does not understand when something is close enough to a command, :-(
17:47
We are needing AI for programing
17:50
Gadi: Yes, that worked perfectly, but before, I was'nt getting the logging failed notice, and now it is appering
17:50
Once more I thank you

MRH2: Sounds like something else then...which version of ltsp (and which distro) is this not working on? (On ltsp 5, the distros behave differently.)

I probably don't know the answer to your problem, but it will help others here to help you if they know that.

if i install fglrx on the machine I am building ltsp5 on will these end up in ltsp?

no
19:53
you have to install it in the chroot
19:53
if your users need it
19:53
but.. gl over the network ain't gonna be fast :)
19:56
<MRH2>
ok let me have a look - do you know if fglrx is just a few files to copy over or is it more involved?

you sure you can't make it work with the open source drivers?

20:13
<johnny>
well, check the support
20:13
you use ubuntu?
20:14
if so. using fglrx or any closed source module will end up costing you 30MB of ram
20:14
on your client
20:14
or at least that's what i was told.. due to the way the modules must be distributed
20:14
unless you build your own custom package
20:16
<MRH2>
i'm ok on the ram front
20:17
don't use ubuntu normally but using it to build the ltsp5 chroot as it seems to be a popular choice
