Hi, I'm experiencing some problem when powering of my thin clients. When choosing to power off in ldm the system hangs. Do I need some special packages on the client root for this to work?
03:05
<johnny>
hangs?
03:06
as in.. it finishes shutting down, but doesn't actually turn the power off?
03:06
you might want to install acpid
03:07
altho.. i'm not quite sure why it isn't in there by default if that is the case
03:07
altho sadly.. it is 4am.. and i must go
03:08
<patrik>
Hangs as in harddrive spins down and then hangs on some of the clients. And on my laptop the screen goes black and the system totally locks up. I must remove the battery to reboot.

<alkisg>
patrik: I don't know what the problem is, but you don't have to remove the battery, you may keep the power off button pressed for 5 seconds to halt your laptop.
03:15
<patrik>
alkisg, That normally works but the hang is so severe that even that stops working :)
03:15
<alkisg>
patrik: you're sure? I've never seen this fail, it's a motherboard, not a CPU thing...
03:15
<patrik>
pretty odd but that is the case
03:15
Yeah I know, but I'm sure about it
03:15
<alkisg>
Wow!!!
03:17
<patrik>
It's a sony vaio ;)
03:17
<alkisg>
patrik, can your laptop shutdown with a normal distro (i.e. not as a thin client)?
03:17
<patrik>
Yes, and if it hands the 5 sec press always work
03:17
s/hands/hangs
03:18
must be an acpi thing. But anyways. Is acpi installed as default on the thin client image?
03:18
<alkisg>
which distro? I've only tried Ubuntu so far
03:19
<patrik>
Yep, it's ubuntu
03:19
<nubae>
you can turn acpi off in the kernel startup parameters
03:19
<alkisg>
Sure, it is. I've only had problems with thin clients not shutting down for very old clients (~1999/2000).
03:21
<patrik>
Do I change that it pxelinux.cfg/default ?
03:21
<alkisg>
Yes, if your clients are pxe. If they're etherboot it's a different story
03:22
<patrik>
they're pxe
03:23
pci=noacpi, right?
03:23
<alkisg>
There's a .pdf with all the kernel parameters at kernel.org, you may try all the acpi related ones... But it's weird that it works normally but not as a thin client...
03:24
<nubae>
not really, I've seen that happen many times with laptops
03:24
mostly due to graphics drivers though
03:25
<alkisg>
Really? Anyway, here's the pdf: www.kernel.org/pub/linux/kernel/people/gregkh/lkn/lkn_pdf/ch09.pdf

nubae, so you use acpi=off to work around the problem?
03:29
<nubae>
I used that to work around some problem, can't remember exactly what it was though

hi,everybody
05:18
I installed the iTalc on ubuntu 8.10 server.but in thin-client I run iTalc can only see the server
05:19
the iTalc cannot add others thin-clients automaticlly,why?
05:23
stgraber,are you online?

05:39
<alkisg>
jackli, do you have a specific question on iTalc?
05:40
<jackli>
alkisg:yes.
05:40
<alkisg>
shoot
05:40
<jackli>
alkisg:I installed iTalc on ubuntu 8.10.
05:41
also installed LTSP on ubuntu 8.10,Now I run italc on thin-client.
05:42
I want to add all thin-clients.But Now I can only see one client.
05:43
<alkisg>
Are there any other users logged on on other thin clients?
05:43
<jackli>
yes,there are 7 users logged on other thin clients
05:44
<alkisg>
OK. Can you see them if you declare them manually?
05:44plamengr has quit IRC
05:44
<alkisg>
I.e. add computer, and use e.g. ip=127.0.0.1:11110
05:44
<jackli>
I can add them use serverIP:10000+thin-client's IP
05:44
<alkisg>
OK. And you want this to be done automatically?
05:44
<jackli>
Yes
05:45
I have 30 clients.
05:45
<alkisg>
Well, if they have static IPs it's simple.
05:45
If they don't, you'll have to patch italc-launcher or change the hostnames, let me find the specific line...
05:47
<jackli>
I also tried to modify the italc-launcher,but it doesnt work.
05:47
<alkisg>
Sorry, I meant ica-launcher
05:47
For the clients, they can't register an avahi service if they use the same name
05:47
...looking...
05:49
OK, I found it, but I don't have the previous version of ica-launcher. Could you paste line 47 which looks like this?
05:49
avahi-publish-service "italc $HOSTNAME$IVSPORT" _italc._tcp $IVSPORT $MD5_1 $MD5_2 $MD5_3 "$HOSTNAME" > /dev/zero &
05:49
I think I only added $IVSPORT there...
05:49
...and the clients have to logoff + logon
05:50
<jackli>
alkisg:could I get your ica-launcher file?
05:50
<alkisg>
I only changed this specific line... anyway, let me pastebot it...
05:50
!pastebot
05:50
<ltspbot>
alkisg: "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.
05:51
<ltsppbot>
"alkisg" pasted "ica-launcher with port in avahi service" (57 lines) at http://pastebot.ltsp.org/161
05:53
<jackli>
alkisg:Thank you,I'll try it.
05:53
<alkisg>
jackli: np. remember that the clients run this upon logon, so they'll have to logoff + logon to see the changes.

alkisg:How can I find the local IP on thin-client, arp -n -a work?
05:57
<alkisg>
I think so. You can also see the IP in ldm, before the clients login.
05:58
You may also use "ps aux|grep ica" to see which clients run ica.
05:58
The last 3 digits are the last byte of their IP.

alkisg:Thank you again.
06:08
<alkisg>
jackli: you're welcome.
06:09
<jackli>
hehe
06:10
alkisg:Are you using LTSP?
06:11
<alkisg>
Yeah, I'm a teacher and most of the labs I'm using are too ancient for anything else.
06:12dirigeant has joined #ltsp
06:13
<jackli>
alkisg:I also want to depoly the LTSP in school.
06:14
and I use Ubuntu,which distribution do you use?
06:15
<alkisg>
Me too, intrepid
06:16
<jackli>
alkisg:hehe,but the LTSP COSTS much memory.
06:17
3GB can only support 10 clients,I mean make them run fluently.
06:17
<alkisg>
RAM is cheap for newer PCs
06:18
<jackli>
I use PC server.
06:18
I am testing the LTSP NOW.
06:21
alkisg:which software are you running mainly,I mean educational soft?
06:21
<alkisg>
We only teach informatics, so we don't use much educational software.
06:21
So mainly OS use, OpenOffice and Internet
06:22
...and a little kturtle or scratch from next year.
06:23
<jackli>
alkisg:I see.
06:23
I installed Gcompris
06:25
<alkisg>
My students are 12-14 years old, I think gcompris is for elementary school
06:25
<nubae>
yeah unfortunately its the case that computers are limited to the 'computer studies' area of studies, instead of being integrated across subjects
06:25
<alkisg>
(you may also ask questions about educational programs in #edubuntu)
06:25
<nubae>
it is, gcompris and childsplay are excellent products for children 3-8
06:26
and take a look at the edubuntu.org website
06:26
there is a list of applications that are well maintained and supported by ubuntu
06:26
ubuntu/canonical
06:27
I found at least in elementary/primary school they use the programs available to them, but in secondary... its just open office and firefox usage
06:27
such a shame... I wish teachers would wake up and realise computers are educational tools in and of themselves.... they aren't a subject
06:28
<jackli>
I use soft just for elementary/primary school.
06:28
<nubae>
then install edubuntu-addon-young from the repos
06:33
<jackli>
nubae:good advice!

09:50gate_keeper_ has quit IRC
09:50
<cyberorg>
Gadi, sure, what do you need?
09:53
<Gadi>
plug in a drive
09:53
check /var/run/ltspfs_fstab for the name of the mountpoint
09:53
<cyberorg>
they are all there
09:53
<Gadi>
run: /usr/sbin/ltspfsmounter $MOUNTPOINT aadd
09:53
*add
09:53
and see what error you get
09:57
<cyberorg>
Gadi, can i paste error in PM?
09:57
<Gadi>
sure
09:57
<cyberorg>
there :)
09:58
<Gadi>
thx
09:58
try:
09:58
unset USER
09:59
/usr/sbin/ltspfsmounter $MOUNTPOINT add
09:59
<cyberorg>
btw these are the first steps i have done already
09:59
same error with unset USER
09:59
<Gadi>
ok - the main issue is disabling the Xauth token stuff
09:59|Paradox| has quit IRC
09:59
<Gadi>
which I thought I had done in ltspfsd
10:00
try this:
10:00
(on the client)
10:00
pkill ltspfsd
10:00
<stgraber>
Gadi: looks like your group thing change fails with pam_group
10:00|Paradox| has joined #ltsp

ltspfsd -a
10:00
<cyberorg>
i also tried ltspfs clientIP:/$MOUNTPOINT somewhere, got error about not finding LTSPFS_TOKEN
10:00
done
10:00
<Gadi>
stgraber: really? how - it uses your code
10:00
grr...
10:01
<stgraber>
Gadi: I'm having a look but pam_group adds the user to audio, video and fuse and I don't get any of these on the thin client

<Gadi>
in that branch
10:26
oh
10:26
you may have an older ltsp-trunk
10:27
<cyberorg>
yes, i pulled from there
10:27
the link you gave
10:27
<Gadi>
right - my ltspfs-trunk but older ltsp-trunk
10:27
<cyberorg>
thats the last commit log
10:28
<Gadi>
right - but your ltsp-trunk has no xinitrc.d stuff
10:28
oh, wait

yes it does

cyberorg- hit ctrl-alt-backspace on the X session
10:30
<cyberorg>
on the client?
10:30
<Gadi>
yeah
10:31
<cyberorg>
nothing happens
10:31
<Gadi>
I moved the S05-set-ltspfs_token from ldm's rc.d to the xinitrc.d dir
10:31
so it applies to all sessions
10:31
something did
10:31
its just not noticeable
10:31
:)
10:32
<cyberorg>
Makefile did not reflect that change, it was still looking for it somewhere else too
10:32
<Gadi>
ah
10:33
<cyberorg>
is revno: 82 the latest?
10:35
<Gadi>
sorry, can you ctrl-alt-backspace again?
10:35
<cyberorg>
done

or not packaged right

you have an old ltsp-common-functions

some of the other scripts fail because they need a function from there
11:10
<johnny>
or just virtualbox Tetrispt ...

if you want to make sure sound works

lbmount hard-codes a lot of things
11:44
:(
11:44
<vagrantc>
sure does.
11:45
<sbalneav>
It has to
11:45* Gadi endeavors to make a kindler, gentler, lbmount
11:45
<Gadi>
why?
11:45
<vagrantc>
it's a setuid root script, so it kind of needs to avoid processing arguments
11:45
<sbalneav>
Yup
11:45
<Gadi>
why cant it just be passed args?
11:45
ah
11:45
<sbalneav>
setuid
11:45
<vagrantc>
because then we have to make absoultely sure they're not pulling anything sketchy
11:45
<sbalneav>
major major major security hole.
11:45
<Gadi>
gotcha
11:45
<vagrantc>
and that's hard.
11:46
<Gadi>
well, then I am at acrossroads
11:46
<vagrantc>
Gadi: tell me about your crossroads... :)
11:46
<Gadi>
shall I fix it enough so that I can have: /media/$dev
11:46
instead of: /media/root/$dev
11:46
or do I leave it be
11:46
and suffer the subdirectory
11:47
<vagrantc>
i dare say suffering is the easiest way here.
11:47
<cyberorg>
Gadi, can i shut down the client now?
11:47
<Gadi>
cyberorg: not yet
11:47
give me a lil bit more

k
11:48
can you do it remote when you are done? its my laptop
11:48
<Gadi>
sure
11:48
<vagrantc>
Gadi: i guess you could make a symlink to it, and behave differently if called as a different binary ... as long as you can make sure that's secure.
11:48* Gadi puts backhand to forehead and martyrs the suffering of the subdir
11:49Eghie has quit IRC
11:49
<vagrantc>
but i guess then a symlink might be able to be crafted such to do evil.
11:52

<sbalneav>I have one computer (ubuntu) in DC (win2003) need centralization /home for all users in /etc/skel
12:05
<Gadi>
cyberorg: still here?
12:06
<sbalneav>
jaspion_me: Well, no, you don't want everyone using /etc/skel, as that's the "default" stuff that's put in a user's home directory when the account is created.
12:07
what you want is /home to be shared out somehow.
12:07
there's two ways to do that.
12:07
1) have /home be on the windows box, and use smbmount or the like to mount the share on /home on the Ubuntu box.
12:08
<cyberorg>
Gadi, yes
12:08
<sbalneav>
2) have the home dires on the Ubuntu box, and export them via samba so that the windows box can mount them.

Gadi, ok, will test that out, not sure how linux xrdp server handles it though

also, make sure your chroot's /usr/share/ltsp/ltsp-common-functions contains "run_parts_list" function

13:01
<Gadi>
is it?
13:01
is it not an asoundconf thing?
13:01
how else do I redirect alsa to pulse locally?
13:02
<ogra>
its a dead ubuntu-ism
13:02
<Gadi>
how does it work now?
13:02
<ogra>
with pulse being the default systemwide its obsolete
13:02
<Gadi>
does that not redirect alsa to pulse?
13:03
<ogra>
right, but with pulse being a system default you dont need that anymore
13:03
<Gadi>
where is the systemwide setting?
13:03
<ogra>
ubuntu.desktop
13:03
s/./-
13:03
or rather gnome :)
13:03
<Gadi>
no, I mean is it a gconf key?
13:03
ah
13:04
so it is a gnome-wide setting
13:04
that doesnt help me :)
13:04

no

hmm... if I include that we should dep on pulseaudio-utils
13:06
<vagrantc>
*sigh* still getting the GID discrepancies with localapps
13:06
<ogra>
you cant include that on the client though i guess it will break ... you dont have X session management client side
13:06
<Gadi>
ah
13:06
<ogra>
(guessing here)
13:06
<Gadi>
hmm...
13:07
can you think of a way I can redirect alsa to pulse on the client?
13:07
<ogra>
but xsmp somewhat suggests it uses the x session management protocol
13:07
you can reimplement "asoundconf set pulse"
13:07
so it works distro agnostic
13:08vvinet has joined #ltsp
13:08
<Gadi>
wait - stgraber: how did a simple export of PULSE_SERVER get audio going for localapp firefox?
13:08
<ogra>
in the end its just setting up a special alsa config
13:09
<Gadi>
ogra: it just create .asoundrc and friends, right?
13:09
<ogra>
right
13:09
i think that works distro independend
13:09
<Gadi>
and those files are read every time an app loads, right?
13:09
<ogra>
no
13:10
<Gadi>
when are they read?
13:10
<ogra>
you have a vitrual alsa device with them ...
13:10
no idea who reads them when, but that virtual device will be there
13:10
worst case you can put the file in /etc
13:11
<Gadi>
hmm
13:11
<ogra>
if you are sure you need it as system device ... which i assume you aill
13:11
*will
13:11
<Gadi>
weird that localapp firefox works with sound
13:11
unless this is not needed at all
13:12
or maybe localapp firefox works because it still uses gnome's defaults since it is running in a session
13:12
and gnome defaults to pulseaudio

figured out the wrong groups thing ...

in /etc/groups, GID 107 is listed twice, once for pulse, and once for fuse.
13:22
so our pruning isn't working quite right.
13:22

doh
13:23
which of those is a server group and not a client group?
13:23

do you have any duplicate names?

how lock network surf for users on ltsp?
14:34
the users can navigate on internal network, how block?
14:35
i think remove local menu on gnome under ubuntu 8.04, but i don't know
14:36
the icon network appearance in nautilus
14:36
=/
14:47
anybody?
14:47
<Gadi>
Guevara: you want to block user's access to the internet?
14:48* Gadi waves to rjune
14:48
<Guevara>
no, block only access internal network (others machines)
14:48
<Gadi>
does the ltsp machine need access to those machines?
14:49
if not, you can setup a firewall
14:49
with rules to deny connections to certain local network IPs
14:49
<Guevara>
=/
14:49
<Gadi>
otherwise, what could your users do on other machines without username/password?
14:50
<Guevara>
the users no need access this machines
14:50
<Gadi>
so setup a firewall
14:50
thats what firewalls do
14:50
how do you keep users on other machines from looking at other machines?
14:50
:)
14:51
<Guevara>
i think in remove icon network on nautilus
14:51
<Gadi>
not sure how easy that is
14:51
<Guevara>
informations Gadi, the users cannot read
14:51
<Gadi>
perhaps it is a gconf key?
14:51
<Guevara>
yes, i use gconf
14:52
but the option for remove i can't see
14:52
i can block others options, panel for exemple
14:53
but, remove or block internal surf network no
14:53
<Gadi>
not sure
14:53
is it the windows network you a re worried about?
14:54
<Guevara>
yes, is windows network and i install ltsp on ubuntu 8.04, and the users on the thinclients can see the local network
14:55
<Gadi>
maybe you can simply uninstall the smb stuff
14:55
:)
14:55
unless you need it
14:55
or change the workgroup
14:55
<Guevara>
yes, maybe i need samba
14:56
but the server need samba
14:56
and the users use samba on the server automaticaly
14:58
<sbalneav>
Unless you set the permissions on files such that the users won't be able to see things, if the data's there, they'll be able to browse it.
14:59
<Guevara>
i can't edit other machines
15:00
<sbalneav>
Then you won't be able to "block" someone's access to things.
15:00
<Guevara>
i search for block this network on gconf, but no sucess
15:00
<sbalneav>
There isn't anything like that in gconf.
15:00
gconf controls gnome. this isn't a gnome function
15:00
this is a file permissions function.
15:00
<Guevara>
this is a option on nautilus
15:01
and how edit this permission?
15:01
<sbalneav>
You're wanting to stop users from accessing /home/something, right?
15:02
<Guevara>
no sbalneav, i block this with sudo chmod 700 * in home dir
15:02
<sbalneav>
ok, so what ARE you wanting to block, then?
15:02
<Guevara>
i need block the users see others machines on windows local network
15:02
<Gadi>
sbalneav: he doesnt want users going to Places > Network
15:03
and searching the windows network
15:03
<Guevara>
yes Gadi
15:03
on nautilus you have a icon "network" and this is a windows network with varios machines
15:03
<Gadi>
unfortunately, it isnt just an icon
15:04
it is a core feature of nautilus
15:04
<Guevara>
i understand
15:04
<Gadi>
and appears everywhere
15:04
<Guevara>
yes
15:04
but i need block this, the students have access, and is not permit
15:04
<alkisg>
Is it possible to cut the traffic to samba ports on a per user basis? That would solve Guevara's problem...
15:05
<Guevara>
yes, but the users use the configuration on the server alkisg
15:06
i can't block for users in this metod
15:06
<alkisg>
That's why I'm saying "on a per user basis", so that only student traffic is blocked, not yuors
15:06
<sbalneav>
I beleive pesselus will do this, however:
15:07
<Guevara>
alkisg: what is you idea?
15:07
<sbalneav>
you could make the /usr/bin/nautilus-connect-server binary chmod 000, and possibly remove/move /usr/share/applications/network-scheme.desktop

usermod -G needs write permission to /etc, not just /etc/group

and the NFS setup doesn't have a writeable /etc

doh!
16:17
(never wouldve caught that one)
16:17
:)
16:17
<vagrantc>
but that's not the worst of our problems, i think...
16:17
<Gadi>
ok, next
16:17
I luv a challenge
16:18* vagrantc is challenged to figure out how to say it
16:18
<Gadi>
youve got dups
16:18
which is better than "you's gots dup'd"
16:18
<vagrantc>
pretty much every group is doubled
16:18
and it doesn't resolve differences in gid
16:19
<Gadi>
ok - did you see that while loop I was talking about?
16:20
<vagrantc>
it's processing /etc/groups, which has the server's "getent group" output appended to it ... but then it processes it one line at a time, and doesn't distinguish if it's processed similar lines already
16:20
similar being identical names or GIDs
16:20
<Gadi>
it should - that's where the match comes in
16:20
<vagrantc>
additionally, /var/cache/ltsp-localapps/passwd and group aren't getting copied back into place after everything's over.
16:21
<Gadi>
but, maybe your write issue with /etc is to blame here, too
16:21
<vagrantc>
Gadi: but the match is matching against the currently processed line ...
16:21
<Gadi>
can you test once you fix /etc as a rw dir?
16:21
<vagrantc>
Gadi: it's matching against itself
16:21
<Gadi>
nope
16:21
look at the code
16:21
it stores the name in a list
16:21
<vagrantc>
ah, yes. got it
16:21
<Gadi>
and then searches the list for that name
16:22* Gadi thinks the issues are all related to writing to /etc/group
16:22
<Gadi>
is all of /var/cace/ltsp-localapps/ writable?
16:22
<vagrantc>
i'm thinking a cleaner approach, would be to keep a pristine copy of the server's getent group output, a pristine copy of the client's original /etc/group ... and then only add groups not already present in to the client's /etc/group
16:23
<Gadi>
because it writes a tmp file there
16:23
<vagrantc>
Gadi: yeah, i fixed that a while ago.
16:23
Gadi: and the restoring those files from /var/cache/ltsp-localapps *was* working at some point
16:23
<Gadi>
well, not sure what would have broken that
16:24
that should happen when localappsd exits
16:24
<vagrantc>
but that's a trivial issue, overall
16:24
<Gadi>
(see the subshell code)
16:24
<vagrantc>
yeah.
16:24
echo "$line" >>${TMPGROUP}
16:25
that needs to check for a matching GID first, and generate a new one if it's already taken
16:25
<Gadi>
right
16:25
I get why you have dup'd ID's
16:25
I dont get why you have dup'd names
16:26
it *sounds like* it breaks on: mv $TMPGROUP /etc/group
16:26
try changing the "mv" to "cp" so you can see what $TMPGROUP looks like
16:26
<vagrantc>
maybe.
16:26
ah, mv.
16:27
tmpgroup is there, so the mv must be failing
16:27
<Gadi>
there ya go
16:27
<vagrantc>
right. because it's a copy on write file.
16:27
er, bind mounted file
16:27
and can't mv it, have to cp it.
16:27
<Gadi>
ok
16:27
ah
16:28
<vagrantc>
or cat it
16:28
without internet access, i managed to crash my computer good ...
16:28* vagrantc fires up X
16:29
<Gadi>
I gotta run - my youngest turns 2 today!
16:29
gotta go party
16:30* Gadi thinks we know the problem and how to solve it, tho
16:30
<vagrantc>
Gadi: thanks for your thinkin!
16:30
Gadi: party hard!
16:30
<Gadi>
and once the gname thing is good to go, we can add the check for gid
16:30
thx

the cp definitely helped, usermod -G still requires write access to /etc, still doesn't copy stuff back to /etc/group and passwd when done ... testing with a writeable /etc now
16:50cyberorg has joined #ltsp
16:52
<vagrantc>
writeable /etc definitely fixes the issue with usermod -G

and the passwd/group stuff doesn't get replaced on logout, but it does seem to get reset properly on the login of the next user

<vagrantc>
except it doesn't even work
17:55
sed -i tries to write in /etc too ... so i'd have to copy the file back out, tweak it, and copy it back

vagrantc, maybe we should just give up on the tmpfs bindmounting..

and move to aufs/unionfs :(

Hi, I want to have a setup where the machine on start-up logs in automatically. Is this doable using LTSP 5 and Ubuntu 8.04
19:15
Please
19:17
<Ryan52>
yep
19:17
!docs

<ltspbot>
Ryan52: "docs" is For the most current documentation, see http://wiki.ltsp.org/twiki/bin/view/Ltsp/LtspDocumentationUpstream
19:17
<Ryan52>
I think that tells you how.
19:18
<alex_21>
Ok, thanks

Ok, not only did I not find it, but I found offensive links on that page
19:23
What I want is the clients to login automatically
19:23
?
19:23
<Ryan52>
alex_21, http://www.ltsp.org/~sbalneav/LTSPManual.html#ldm-variables
19:23
LDM_AUTOLOGIN
19:23
see that section
19:24* Ryan52 doesn't see the offensive links
19:26
<alex_21>
Well, that is subjective I suppose,
19:28

Well, anyways, I can't find the section. I looked, but I don't see it
19:36
I really looked
19:39* Ryan52 wonders how you can miss it...
19:39
<Ryan52>
it right there.
19:39
just open the link I gave you.
19:39
LDM lts.conf parameters
19:39
LDM_AUTOLOGIN
19:39
boolean true/false, default <unset>
19:39
This option allows the thin client to login automatically without the need for a username and password. To set it set LDM_AUTOLOGIN = True for the corresponding thin client. You can also set a user and password with LDM_USERNAME = John and LDM_PASSWORD = John's password, although not setting these will default to the hostname of the thin client.
19:39
LDM_DIRECTX

oops, one line too many.

but ya.

I have a question... re rdesktop with ltsp.
23:41
can't seem to get anywhere with power settings... screen blanking
23:42
i checked the ltsp wiki but the DPMs settings which are supposed to be enter in the lts.conf don't do a/t
23:43
also, can't really find e/o that is running into the same issues i have.
23:44
basically, i'm using rdesktop from the SCREEN_02 and on the windozz server i've set the screen saver not to turn on but after 10 mins the thin clients turn off their screens.
23:44
does anyone have addition data on this?
23:45
