| 03:05 | <patrik> 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.

| 03:10 | try2free has left #ltsp | |
| 03:13 | <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

| 03:28 | <alkisg> 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
| |

| 03:51 | <patrik> thanks by the way

| 05:14 | <jackli> 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?

| 05:34 | <jackli> who knows iTalc under LTSP?
| |
| 05:37 | Chidder has joined #ltsp | |
| 05:39 | edmar has joined #ltsp | |
| 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?
| |
| 05:44 | plamengr 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.

| 05:54 | <jackli> alkisg:I see.
| |
| 05:54 | ogra has joined #ltsp | |
| 05:55 | <jackli> 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.

| 05:58 | <alkisg> (of the port, I mean)

| 06:07 | <jackli> alkisg:Thanks again.
| |
| 06:07 | 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.
| |
| 06:12 | dirigeant 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!

| |
| 09:48 | cyberorg: is it possible to get someone on a thin client shell and get some troubleshooting going?
| |
| 09:50 | gate_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 $MOUNTPOINT add
| |
| 09:59 | <cyberorg> btw these are the first steps i have done already
| |
| 09:59 | same error with unset USER
| |
| 09:59 | <Gadi> ok - the main issue is disabling the Xauth token stuff
| |
| 09:59 | |Paradox| has quit IRC | |
| 09:59 | <Gadi> which I thought I had done in ltspfsd
| |
| 10:00 | try this:
| |
| 10:00 | (on the client)
| |
| 10:00 | pkill ltspfsd
| |
| 10:00 | <stgraber> Gadi: looks like your group thing change fails with pam_group
| |
| 10:00 | |Paradox| has joined #ltsp | |
| 10:00 | <Gadi> ltspfsd -a
| |
| 10:00 | <cyberorg> i also tried ltspfs clientIP:/$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

| 10:25 | <Gadi> cyberorg: do you have the xinitrc.d dir?
| |
| 10:26 | <cyberorg> Gadi, on the server?
| |
| 10:26 | <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
| |
| 10:28 | yes it does
| |
| 10:30 | japerry has quit IRC | |
| 10:30 | <Gadi> 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
| |
| 10:35 | btw i am connected to the server via rdp

| |
| 11:04 | <sbalneav> Tetrispt: You'd be looking for X for windows.
| |
| 11:04 | Something like Cygwin/X

| |

| |
| 11:05 | <Gadi> cyberorg: parts of your chroot are broken
| |
| 11:05 | or not packaged right
| |
| 11:05 | you have an old ltsp-common-functions
| |
| 11:06 | some of the other scripts fail because they need a function from there
| |
| 11:10 | <johnny> or just virtualbox Tetrispt ...
| |
| 11:10 | if you want to make sure sound works
| |
| 11:10 | if you want test usb.. you need the non open source version :(

| |
| 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
| |
| 11:47 | <cyberorg> 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 | |
| 11:49 | Eghie has quit IRC | |
| 11:49 | <vagrantc> but i guess then a symlink might be able to be crafted such to do evil.
| |
| 11:52 | <johnny> Gadi, no no no.. apply the backhand to the subdir
| |
| 11:52 | jaspion_me has joined #ltsp | |
| 11:55 | <jaspion_me> I need help for centralization /home default in directory /etc/skel for all users
| |
| 11:55 | <sbalneav> jaspion_me: Why don't you tell us what you'd like to do?
| |
| 11:56 | sepski has joined #ltsp | |
| 12:01 | davidj has quit IRC | |
| 12:03 | <jaspion_me> <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.
| |
| 12:08 | <cliebow> (have used pam_mount for this years ago)
| |
| 12:09 | <Gadi> cyberorg: I pushed a new branch that should fix things
| |
| 12:09 | but you need to redirect /media/root
| |
| 12:09 | instead of /media
| |
| 12:10 | <cyberorg> Gadi, ok, will test that out, not sure how linux xrdp server handles it though
| |
| 12:10 | <Gadi> also, make sure your chroot's /usr/share/ltsp/ltsp-common-functions contains "run_parts_list" function
| |

| |
| 12:11 | <Gadi> shall I shut down ur laptop?
| |
| 12:11 | <cyberorg> does that also fix PULSE_SERVER export for rdesktop?
| |
| 12:11 | <Gadi> oh, no
| |
| 12:11 | I should add that to ltsp-trunk
| |
| 12:11 | <radoeka> #opensuse-kde
| |
| 12:13 | <cyberorg> Gadi, laptop down now, thanks for all the troubleshooting, 'night :)

| |
| 12:23 | <sbalneav> jaspion_me: If you want to have "the same" stuff in all users home directories, I'd suggest using symbolic links to the shared content, or simply setting up a shared directory where the common stuff can be found. i.e. /home/share

| |
| 12:29 | <xxxcgn> after installing it it just does not work and my internet connection lost, too
| |
| 12:29 | <cliebow> it is a wip..
| |
| 12:30 | <sbalneav> Have you read the documentation?
| |
| 12:30 | <xxxcgn> i made all what is told in the howto, but after installing it i tried to start it
| |
| 12:30 | <sbalneav> they have a section in the manual:

| |

| |
| 12:44 | <Gadi> stgraber: dont forget to pull first
| |
| 12:44 | I committed two today
| |
| 12:44 | <stgraber> Gadi: yeah, saw that, I thought I pushed my changes but I didn't. So I'm uncommiting mine + pulling + commiting again + pushing, then tag

| |

| |
| 12:49 | if you need to unset it there
| |
| 12:51 | sepski has joined #ltsp | |
| 12:51 | <Gadi> well, what if OLD_IFS was ","

| |
| 12:52 | <vagrantc> but unsetting it before resetting it ...
| |
| 12:52 | * vagrantc always found IFS tricks to be a bit on the ugly side | |
| 12:52 | <Gadi> yes, yes - so you've said
| |
| 12:53 | mr: [-n "$this$that$theother" ]
| |
| 12:53 | ;)
| |
| 12:53 | <vagrantc> heh
| |
| 12:53 | well, i had mixed feelings over that, so i confirmed before comitting :)

| 13:00 | <vagrantc> Gadi: asoundconf set-pulseaudio is an ubuntu-ism.
| |
| 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 | <ogra> no
| |
| 13:04 | its in /etc/xdg7autostart
| |

| 13:05 | <ogra> Name=PulseAudio Session Management
| |
| 13:05 | Comment=Load module-x11-xsmp into PulseAudio
| |
| 13:05 | <Gadi> 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
| |
| 13:08 | vvinet 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
| |
| 13:17 | jaspion_me has quit IRC | |
| 13:18 | <vagrantc> seems like /etc/groups doesn't get reset properly
| |
| 13:21 | aha!
| |
| 13:21 | figured out the wrong groups thing ...
| |
| 13:22 | 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 | <Gadi> doh
| |
| 13:23 | which of those is a server group and not a client group?
| |
| 13:23 | <vagrantc> seems like all GIDs below 500 are repeated twice
| |
| 13:24 | <Gadi> do you have any duplicate names?
| |
| 13:24 | or only duplicate ids?
| |
| 13:25 | hanthana has quit IRC | |

| |
| 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
| |
| 15:08 | warren has quit IRC | |
| 15:08 | <Guevara> =/
| |
| 15:09 | <sbalneav> Other than that, I don't see any nautilus gconf keys that would affect that.
| |
| 15:09 | <Guevara> i understad
| |
| 15:09 | =/
| |
| 15:12 | <sbalneav> Easier would be to simply, on the other server, make the shares non browsable
| |
| 15:12 | <Guevara> no, is very complicated
| |
| 15:12 | vvinet has quit IRC | |
| 15:13 | <alkisg> Guevara, I was thinking something like iptables => drop packets with destination port = 135 to 139 and userid <> teacher
| |
| 15:14 | But I don't know if it is doable.
| |
| 15:14 | <Guevara> =/
| |
| 15:15 | ltsp need more options for this
| |
| 15:15 | <sbalneav> That isn't an LTSP function
| |
| 15:15 | it has nothing to do with LTSP
| |
| 15:15 | decebal has joined #ltsp | |
| 15:15 | <sbalneav> It's something GNOME doesn't offer
| |
| 15:15 | gnome != LTSP
| |
| 15:16 | <Guevara> understabd
| |
| 15:16 | understand
| |
| 15:16 | <sbalneav> Youd have exactly the same problem if you set up a standalone workstation with a hard drive for people to log in on.
| |
| 15:18 | <Guevara> yes, but i need block this on ubuntu
| |
| 15:19 | in the debians tutorials cannot this information
| |
| 15:22 | <sbalneav> I don't understand
| |
| 15:23 | <alkisg> Guevara: why don't you cut all smb traffic? Who needs to access windows shares? The teachers?
| |
| 15:23 | <sbalneav> Are you saying they HAVE this information on the debian tutorial?
| |
| 15:23 | <rjune> sbalneav, ltsp > gnome
| |
| 15:23 | <sbalneav> ltsp < gnome
| |
| 15:24 | there's way more work in gnome than ltsp
| |
| 15:24 | ltsp's plumbing
| |
| 15:24 | brb
| |
| 15:24 | <rjune> alkisg, iptables does support matching by user
| |
| 15:24 | decebal has left #ltsp | |
| 15:25 | <Guevara> i not installing the packages for samba
| |
| 15:25 | <alkisg> Yeah, I saw that on the man page, I'm just not familiar with the syntax and I can't give Guevara the exact line...
| |
| 15:25 | <Guevara> automatically the server and the thiclients access this windows network
| |
| 15:25 | <alkisg> Guevara: ok, why don't you remove smb support?
| |
| 15:26 | (like Gadi told you)
| |
| 15:26 | <sbalneav> Guevara: Did you TRY chmodding the nautilus-connect-server and moving the .desktop file yet?
| |
| 15:28 | gate_keeper_ has quit IRC | |
| 15:28 | <rjune> iptables -m owner -h will list the help
| |
| 15:28 | <Guevara> sbalneav: thanks for help, but i have in home, not in the universuty, the ltsp is in university
| |
| 15:28 | <rjune> iptables -A OUTPUT -j DROP -m owner --gid-owner GID_OF_STUDENTS should match it
| |
| 15:29 | though it's probably better to do it as two rules, one that allows a teacher group, then one that blocks it unilaterally

| 16:16 | Gadi: i've been struggling to figure out the groups issue without internet access ... made any progress on that?
| |
| 16:16 | i've found a couple issues ...
| |
| 16:16 | <Gadi> ok, shoot
| |
| 16:16 | <vagrantc> usermod -G needs write permission to /etc, not just /etc/group
| |
| 16:16 | and the NFS setup doesn't have a writeable /etc
| |
| 16:16 | <Gadi> 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

| 16:49 | <vagrantc> 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
| |
| 16:50 | cyberorg has joined #ltsp | |
| 16:52 | <vagrantc> writeable /etc definitely fixes the issue with usermod -G

| |
| 19:23 | see that section

| 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.
