hi
15:07
<dyn>
If Alice plugs in a USB stick it shows up on Bob's desktop... yet they have no permissions (obviously) to muck with it.
15:07
I'm using LTSP Ubuntu Hardy
15:07
this seems... problematic
15:07
<supreme_>
how can i do to remote supervision of desktops?
15:08
<dyn>
supreme_: checkout x11vnc
15:08
<supreme_>
ok, thanks
15:08
<dyn>
sure
15:09
<mirttex>
dunno if this is the right channel but i'm only trying to export my X, with xdmcp, the server runs a Debian amd64, and if the client is 64 it runs ok. but if i try X -query on a 32 client i doesn't work. is this ok?
15:12
<supreme_>
dyn, im trying to install x11vnc in chrooted client system, the problem is that when i do chroot /opt/ltsp/i386/ i got: "/bin/bash: error while loading shared libraries: /usr/lib/libesd.so.0: cannot open shared object file: No such file or directory"
15:14
i made it, with sudo chroot... (i was as root doing before, but for some reason that thing just didnt works)

dyn, when i do chroot i have x11vnc in chrooted system, but when client boots it says x11vnc: no such file or directory or some
15:38
<warren>
hmm
15:38
are the env variables from lts.conf available during ldm's rc.d scripts?
15:38
<supreme_>
i cannot understand how in chrooted system command exists but in client console doesnt
15:38
i dont know
15:38
how can i do to know?
15:40spectra has quit IRC
15:40
<supreme_>
better, how can i do to make available those variables?
15:40
<Gadi>
warren: depends
15:40
not all
15:40
<warren>
which then?
15:40
<Gadi>
only those exported by ldm.c
15:40
LDM_USERNAME, LDM_SESSION, LDM_SERVER, LDM_SOCKET, and some others
15:40
afaik
15:40
DISPLAY, I think
15:41
<warren>
For example, I want to set the keyboard layout during rc.d instead of in configure-x.sh
15:41
I'm eliminating the need for configure-x.sh
15:41
<Gadi>
cool - what about touchscreen? ;)
15:41
<warren>
well
15:41
<Gadi>
one sec
15:41
brb
15:41
<warren>
I guess configure-x.sh can do less
15:42jammcq has quit IRC
15:42
<supreme_>
i have an script that do x11vnc -display :6 -forever -loop & , i checked that x11vnc exists when i chroot from an client xterm, i checked that this script run when boot, because a message appears at booting telling me that x11vnc doesnt exists
15:43
<warren>
Gadi: actually fedora 9 will autoconfigure touchscreens if you have the right packages installed. I don't know how it works though,
15:46macjunkie has joined #ltsp

<macjunkie>
i'm having a problem with my install of ltsp my colleagues replaced all the mice with 3 button usb mice
15:46
and now of the mice work
15:46
we're running ltsp 4.2 on centos 5
15:47
i found a thing on google about adding some modules and stuff to ltsp.conf but when the clients boot its saying it can't find those modules and that it can't find /proc/bus/usb
15:52staffencasa has joined #ltsp
15:53
<johnny>
MacIver, sorry.. i don't know anything about ltsp 4.2.. only 5
15:53
err
15:53
sorry
15:53
macjunkie that is
15:53
<macjunkie>
yeah figured as such
15:54
argh
15:54
<supreme_>
somebody?
15:56dyn has quit IRC
15:57
<macjunkie>
anyone else know anything about 4.2 since its still listed ont he webpage... until theres support for centos / rh can't really upgrade
15:57
and i'd rather not run a .0 release on a production machine
15:59
<supreme_>
macjunkie, im using ltsp4.2 in rhel4
15:59
<macjunkie>
any luck with usb devices on your clients? the mice don't work
15:59
<supreme_>
its working fine, all usb works fine, localdev too
15:59
<macjunkie>
i tried goolging and found some stuff about adding some modules for usbhci into ltsp.conf
15:59
weird
15:59
<supreme_>
usb worked out of the box
16:00
<macjunkie>
hrm
16:00
<supreme_>
i think could be your hardware
16:00
my clients are ebox
16:00
ebox2
16:03
macjunkie, your usb disk worked in usb?
16:03
*works
16:03
if mouse doesnt work, maybe protocol too
16:04Nuba1 has joined #ltsp
16:05Faithful has quit IRC
16:07
<supreme_>
i cannot make x11vnc works to watch clients desktops
16:07
<Gadi>
supreme_: did you install it in the chroot?
16:07
its not there by default
16:07
sudo chroot /opt/ltsp/i386 apt-get install x11vnc
16:08
<supreme_>
i chrooted into /opt/ltsp/i386/ and command x11vnc exists
16:08
<macjunkie>
the only usb devices on the clients are the mice
16:08
<Gadi>
supreme_: sudo chroot /opt/ltsp/i386 dpkg -l x11vnc
16:09
macjunkie: what happened exactly? new usb mice dont work?
16:09
<supreme_>
macjunkie, try an usbdisk
16:09
<Gadi>
can you pastebot lts.conf?
16:09
<macjunkie>
yeah one of my colleagues replaced all the mice in this lab with usb mice
16:09
<Gadi>
!pastebot
16:09
<macjunkie>
yeah
16:09
<ltspbot>
Gadi: "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.
16:09
<macjunkie>
hang on
16:10
<ltsppbot>
"macjunkie" pasted "usb mice no workie" (15 lines) at http://pastebot.ltsp.org/553
16:10
<macjunkie>
the commented out modules were what i found when i googled
16:11
but those modules don't exist in my install of 4.2 appearntly
16:11
<Gadi>
and do the mice move at all or are they dead?
16:11
<macjunkie>
they don't move at all
16:11
<Gadi>
try setting X_MOUSE_PROTOCOL = "auto"
16:11
<supreme_>
Gadi, i can execute x11vnc in chrooted system, i cannot do dpkg since i dont use debian based distro
16:12
<Gadi>
supreme_: what distro?
16:12
<supreme_>
rhel
16:12
<Gadi>
chroot /opt/ltsp/i386 rpm -a|grep x11vnc
16:12
:)
16:12
er, rpm -qa
16:12
been a while :)
16:12
<macjunkie>
nope
16:13
we saw a error when it boots about not being able to find /proc/bus/usb
16:13
<supreme_>
i actually did first sudo chroot... and then rpm, but it says that rpm doesnt exists, did you mean bot commands together?
16:13
<Gadi>
macjunkie: are they optical mice?
16:13
<macjunkie>
yeah
16:13
<Gadi>
does the laser come on?
16:13
<macjunkie>
nope
16:13
<Gadi>
ah, then it is a module thing
16:13
<supreme_>
macjunkie, the problem is module
16:14
since usb arent even active
16:14
in clients
16:14
<Gadi>
well, you dont need /proc/bus/usb
16:14
<macjunkie>
oh ok
16:14
<Gadi>
but, you do need the right usb module
16:14
hmm...
16:14
what kind of client?
16:14
<macjunkie>
the clients are hp xw4400's
16:14
<supreme_>
Gadi, i cannot do chroot /opt/ltsp/i386 rpm -a|grep x11vnc
16:15
<Gadi>
supreme_: I meant: chroot /opt/ltsp/i386 rpm -qa|grep x11vnc
16:15
<macjunkie>
server is a hp dl 360 g3 running centos 4
16:15
<Gadi>
sorry - forgot the q
16:15
macjunkie: try: MODULE_01 = usb-ohci
16:16
<supreme_>
/usr/sbin/chroot: cannot run command `rpm' :not such file or directory or some
16:16
<Gadi>
ah, ok
16:16
how did you install x11vnc in the chroot?
16:16
not via rpm?
16:17
<supreme_>
Gadi, x11vnc actually run into chrooted, out of the box
16:17
isnt installed on server root system
16:17
<Gadi>
ls /opt/ltsp/i386/usr/bin/x11vnc
16:17
<supreme_>
but in chrooted system it is
16:17
ok
16:17
<Gadi>
like that?
16:17
<supreme_>
:o isnt here
16:17
damn
16:18
why i can executed in chrroted then?
16:18
<Gadi>
when you chroot to /opt/ltsp/i386
16:18
do: which x11vnc
16:18
<supreme_>
in chrooted?
16:18
<Gadi>
yeah
16:18
<macjunkie>
ok got an error can't load /lib/modules/2.6.20.9-ltsp-1/modules.dep
16:18
error loading usb-ohci
16:19
<supreme_>
which: command not found
16:19
<Gadi>
macjunkie: enable a shell on the client
16:19
<macjunkie>
and looking /opt/ltsp/i386/lib/modules has 2.6.16.1-ltsp2 and 2.6.17.8-ltsp-1
16:19
is all i see ther
16:19
gadi > how do i do that?
16:19Nubae has quit IRC
16:20
<Gadi>
SCREEN_01 = shell
16:20
<macjunkie>
ok
16:20
<Gadi>
or
16:20
actually: SCREEN_02 = shell
16:20
then, you can ctrl-alt-f2 to get to it
16:20
and have X on ctrl-alt-f1
16:22
<macjunkie>
ok
16:22
in a shell now
16:22
<Gadi>
cool
16:22
cat /proc/modules|grep usb
16:22
<macjunkie>
nothing
16:23
<Gadi>
modprobe usb-uhci
16:23
cat /proc/modules|grep usb
16:23
<macjunkie>
can't load /lib/modules/2.6.20.9-ltsp-1/modules.dep no such file or directory
16:25
<Gadi>
sounds to me like you are booting a kernel you don't have modules for
16:25
:)
16:25
<macjunkie>
yeah me too
16:26
<Gadi>
your problem has nothing to do with USB
16:26
:)
16:26
<macjunkie>
i was googling to see if there a modules package for that kernel
16:26
<Gadi>
can you pastebot dhcpd.conf?
16:26
<macjunkie>
i remember downloading that kernel when i upgraded our ltsp to 4.2
16:26
sure
16:26
<Gadi>
you should just go back to a kernel you have moduls for
16:26
unless you have need for that particular kernel?
16:26
<macjunkie>
not really
16:27
<Gadi>
edit you dhcpd.conf
16:27
and replace the kernel references with the newer of the two you found in /opt/ltsp/i386/lib/modules
16:27
<ltsppbot>
"macjunkie" pasted "dhcpd.conf" (9 lines) at http://pastebot.ltsp.org/554
16:28
<Gadi>
thats not all of it, is it?
16:28
<macjunkie>
that was the entry for one of the clients
16:29
<Gadi>
ah, yeah
16:29
so modify the kernel version to: 2.6.17.8-ltsp-1
16:29
<macjunkie>
yeah just did
16:29
:)
16:29
<Gadi>
and then you should be good to go
16:29
<macjunkie>
booting the client now
16:29
<Gadi>
dont forget to restart dhcpd
16:30
<macjunkie>
yaeh yeah I forgot that too :D
16:30
<Gadi>
:)
16:30
rookie :P
16:30
<macjunkie>
now i'm getting an error saying it can't auto detect the network card
16:30
and its not booting
16:30
which is why i switched to 2.6.20 if i remember right
16:31
<Gadi>
ah - well that explains your new kernel
16:31
:)
16:31
you just forgot its modules
16:31
where did you get the kernel from?
16:32
<macjunkie>
http://ltsp.mirrors.tds.net/pub/ltsp/ltsp-4.2/
16:32
<Gadi>
grab the ltsp-modules pkg
16:32
the tgx
16:32
*tgz
16:32
<macjunkie>
yeah
16:32
just found it :)
16:32
<Gadi>
copy it to: /opt/ltsp
16:33
then, cd /opt/ltsp
16:33
<macjunkie>
done
16:33
<Gadi>
and: tar xvfz <filename>
16:33
I am pretty sure it unpacks to i386/
16:33
<macjunkie>
ya
16:33bobby_C has joined #ltsp
16:33
<Gadi>
then, change kernel back, restart dhcpd
16:34
and you should be ok
16:34
<macjunkie>
yea doin now
16:34
and restarted dhcp this time :)
16:35
ok now its picking up the usb mouse
16:35
but its saying loading module usb-ohci failed
16:35
and its stopping
16:35
<Gadi>
yeah, take that out of lts.conf
16:35
<macjunkie>
yea
16:35
<Gadi>
it was a hail mary
16:35
<macjunkie>
jsut did
16:35
:)
16:35
<supreme_>
nice! i think x11vnc in ltsp4.2 comes installed , cause i already found it in /usr/X11R6/bin/x11vnc
16:35
<Gadi>
:)
16:35
supreme_: ah, you are using 4.2?
16:36
i didnt catch that
16:36
sorry
16:36
supreme_: if you write your own script to start it, use absolute path
16:36
when calling it
16:37
<macjunkie>
yay!!!!
16:37
thanks!!!
16:37
<Gadi>
(/usr/X11R6/bin is not in PATH by default)
16:37* macjunkie does the happy dance
16:37
<macjunkie>
laters

16:37macjunkie has quit IRC
16:42
<supreme_>
Gadi, apparently i get workin x11vnc in clients
16:42
i just replaced x11vnc with full path
16:42slidesinger has quit IRC
16:42
<supreme_>
now the problem is that i got connection refused
16:44
<Gadi>
supreme_: you should also boot to a shell on SCREEN_02
16:44
and test there
16:45
<supreme_>
ill do that now
16:46
obviously i have to change display :6 for the display that i have X right? i mean, if i have SCREEN_02= startx the command should be x11vnc... display :2?
16:49
<Gadi>
no :1
16:49
screen number minus 1
16:50mikkel has quit IRC
16:51
<supreme_>
i got:: connection to ":0.0" refused by server
16:51
xlib : no protocol specified...
16:52
im using :/usr/X11R6/bin/x11vnc -display :2 -forever -loop &
16:52alkisg has joined #ltsp
16:52
<supreme_>
sorry, i already changed 2 by 0 /usr/X11R6/bin/x11vnc -display :0 -forever -loop &
16:52
that is the command.
16:53
<Gadi>
try setting: DISABLE_ACCESS_CONTROL = Y
16:53
in lts.conf
16:53
<supreme_>
ok
16:53
<Gadi>
(i think that was the param ) :)
16:54
<supreme_>
ok :) i remember have read that... lets see
16:55
<Gadi>
now, didnt LTSP 4.2 do the x11vnc stuff as an lts.conf param?
16:55
I dont think you need to write a script
16:57
try just setting: X4_MODULE_01 = vnc
16:57
and disable your script
16:57juanpaul has quit IRC
16:59
<supreme_>
Gadi, after boot with DISABLE_ACCESS_CONTROL = Y, and run x11vnc command in screen_01 shell, i get ***unrecognized options(s) loop, for a list of options run:x11vnc -help
16:59
<Gadi>
supreme_: do this:
16:59
1. disable your script
16:59
2. SCREEN_01 = startx
16:59
<supreme_>
ok
16:59
<Gadi>
3. SCREEN_02 = shell
16:59ogra_cmpc has quit IRC
17:00
<Gadi>
4. X4_MODULE_01 = vnc
17:00
5. reboot the client
17:00
6. vncviewer <client>
17:00
I think that should work
17:00
but make sure SCREEN_01= startx
17:01bobby_C has quit IRC
17:01
<supreme_>
ok
17:01
doing it.
17:01
..
17:01
what about disable access control?
17:02
<Gadi>
I dont think its necessary
17:02
try without
17:02
<supreme_>
trying...
17:02
<Gadi>
then enable if it doesnt work
17:02
I *believe* this will use the X vnc module (rather than using x11vnc)
17:03
I think that code was merged into 4.2
17:03
<supreme_>
the freaking thing is almost working!!
17:03
:D:D:D
17:04
<Gadi>
almost?
17:04
<supreme_>
the only problem is that is asking me for a passwd
17:04
<Gadi>
ah right
17:04
do this:
17:04
run vncpasswd on the server
17:04
then copy ~/.vnc/passwd that it creates to: /opt/ltsp/i386/root/.vnc/passwd
17:05
(you will need to create /opt/ltsp/i386/root/.vnc directory
17:05
<supreme_>
done, rebooting client
17:05
:)
17:05
i hope it works
17:06
<Gadi>
should
17:09
<supreme_>
the freaking thing ACTUALLY WORKS!!!
17:09
:D:D:D:D:D:D::D
17:09
its SO working!!!
17:09
<Gadi>
cool
17:09* laga breaks it again
17:09
<supreme_>
omg!!! OsoMG! thanks Gadi
17:09
<Gadi>
congrats
17:09
and with that, I gotta go
17:09
happy friday
17:10
<supreme_>
ok, thanx , i hope u be well

did you see my /quote ?
19:49
i'm using irc via my jabber transport
19:49
it's not 100% perfect
19:51stgraber_ has joined #ltsp
19:52
<Nubae>
yeah jabber has had problems for as long as I can remember
19:52stgraber has quit IRC
19:52
<Nubae>
but think its just chat clients in general... complicated stuff
20:00
<johnny2>
huh?
20:00
i've been using it for years?
20:00
what problems are you speaking of?
20:01
i'm talking about this irc transport specifically
20:01
it doesn't know how to use /msg properly it seems
20:01
the transport does one connection for each channel
20:01
instead of one server join and multiple channel joins
20:01
that's it's main problem.. but i'd have to learn erlang to fix it
20:02
<Nubae>
the jabber transport itself and other plugins for jabber have always been problematic for me
20:03
icq msn and the other common ones work fine, true
20:04
I'm assuming I've been using it for years was a statement and not a question ;-)
20:05* Nubae wishes he could go to FOSSED looks like its gonna be real interesting
20:17
<johnny2>
probelmatic in what way?
20:17
i'm doing something out of the norm, so i was expecting problems
20:19
<Nubae>
well to be honest, it was years ago I was trying to integrate jabber into a web based app...
20:20
well, coders working with me... and I just remember having heaps of problems with the jabber transport
20:20
<johnny2>
jabber transport?
20:21
<Nubae>
jabber to jabber as opposed to its ability to do icq, msn aol, or others
20:22
<johnny2>
lol
20:22
why was the intent?
20:22
err what*
20:23
<Nubae>
use it as an internal messaging system
20:23
<johnny2>
anybody happen to know a good way to sync passwords between firefox installs? other than google stuff
20:23
<Nubae>
web based...
20:23
<johnny2>
sure.. but why did you need a transport?
20:23
i used muckl for mine .. simple enough
20:23
but when you tried, bosh wasn't developed i bet
20:24
<Nubae>
well we wanted to do multiple users at once, like irc
20:24
<johnny2>
bidirectional over http
20:24
with sasl anonymous for multiple users without accounts
20:24
<Nubae>
nope, like I said, this was years ago
20:24
<johnny2>
yeah.. too early
20:24
it's all much easier now
20:24
just need ejabberd and muckl
20:25
<Nubae>
I've got to get back into it all anyway, for OLPC
20:25
gotta test ejabberd with the XS servers and Xos
20:25
<johnny2>
the serverless stuff via zerconf/avahi works nicely
20:25
<Nubae>
gotta look at the load balancing options
20:25
<johnny2>
used it with pidgin and gajim
20:25
<Nubae>
yeah, that's all part of the stuff they're doing with the wirelss mesh
20:26
I always thought using pure ip 6 would be the best way though
20:26
multicasting already included, encryption, no dhcp...
20:26
ip 6 sounds perfect
20:26
for it
20:27
<johnny2>
yeah
20:27
<Nubae>
even if you used it on top of ip 4
20:27
<johnny2>
but at least apipa still works
20:27
<Nubae>
tunnels quite well...
20:27
<johnny2>
for pure ip4
20:28
even if it's not completely ideal
20:28
<Nubae>
but no one seems interested in going the ip 6 route yet
20:28
<johnny2>
yeah.. it's sad
20:28
it's a slow process
20:28
google is finally available over ip6
20:28
that's a good start
20:28
all the root servers work with AAAA records now
20:28
i need to set some up
20:28
as i have a tunnel broker acount
20:29
sadly it's native.. unless i moved my linode to fremont
20:29
<Nubae>
its funny if you try and look for web sites that have ip 6, even the w3c doesn't have it done yet
20:29
and we're supposed to be done moving the net to it by 2012...
20:30
<johnny2>
things will move quick tho
20:30
once the giants jump on
20:30
<Nubae>
maybe mobile devices will be the final push
20:30
yeah... just needs a couple giants too

Hi. anyone familiar with MiniME?, a PCLinuxOS mini remaster?
20:57
I installed everything and ltspcfg shows YES for everything, however i get a PXE-E3B msg on the clients
20:57
path, folders and files are where they should be
20:58
I am stuck :(

<johnny>
dagaz, that's ltsp4 i think
21:36
you should try a distro that has ltsp5 support
21:37
ubuntu or debian atm
21:37
soon officially gentoo and fedora
21:38
<dagaz>
yes I have ltsp4 on this box
21:39juanpaul has quit IRC
21:39
<dagaz>
thought it should work on pclos, guess not :(
21:43
How about kubuntu? ltsp5 supported?
21:45
<Nubae>
or suse
21:46
kubuntu is ubuntu with a kde shell so yes
21:48
<dagaz>
ok.. guess I have to say goodbye to my beloved PCLinuxOS
22:08
I give kubuntu a shot... thanks

dagaz, or you could get somebody to port it to pclinuxos :)
22:48
it's prolly not super hard..
22:58
<Nubae>
isnt pclinux based on ubuntu?
23:05
<johnny>
if that is true.,. then it won't be super hard.. :)
23:05
dagaz, pay attention :)
23:05* johnny can't keep on top of all the distributions out there
