15:07	<supreme_> 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)
15:24	twinprism has joined #ltsp

15:27	generic has quit IRC
15:31	juanpaul has joined #ltsp
15:36	<supreme_> 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?
15:40	spectra 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
15:42	jammcq 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,
15:46	macjunkie has joined #ltsp
15:46	<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
15:52	staffencasa 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?
15:56	dyn 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
16:04	Nuba1 has joined #ltsp
16:05	Faithful 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?
16:19	Nubae 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
16:33	bobby_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
16:37	<Gadi> l8r
16:37	macjunkie has quit IRC
16:42	<supreme_> Gadi, apparently i get workin x11vnc in clients
16:42	i just replaced x11vnc with full path
16:42	slidesinger 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
16:50	mikkel 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 &
16:52	alkisg 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
16:57	juanpaul 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
16:59	ogra_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
17:01	bobby_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
17:10	see ya

19:45	<Nubae> ??
19:46	Q-FUNK has quit IRC
19:48	<johnny2> did you see my /quote ?
19:49	i'm using irc via my jabber transport
19:49	it's not 100% perfect
19:51	stgraber_ has joined #ltsp
19:52	<Nubae> yeah jabber has had problems for as long as I can remember
19:52	stgraber 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

20:56	<dagaz> 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

21:36	<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
21:39	juanpaul 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

22:47	<johnny> 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
