| 02:57 | <obrienmd> Any idea what kernel options are appropriate for named new-style nbd root on LTSP on Ubuntu Oneiric? I'm using nbdname=xyz, but need to also tell it which server to use. I've tried 'nbdroot=1.2.3.4 nbdname=xyz', but it doesn't seem to work, keeps saying connection refused... Server is on port 10809 (default).

| 04:09 | <alkisg> Good morning
| |
| 04:10 | vagrantc: wouldn't it be possible in $ROOT/usr/sbin/policy-rc.d to detect when we're chrooted, and automatically `exit 101`, instead of having to set LTSP_HANDLE_DAEMONS=false before chroot'ing?
| |
| 04:11 | E.g. http://paste.ubuntu.com/702053/
| |
| 04:12 | <vagrantc> alkisg: good evening :)
| |
| 04:12 | <alkisg> :)
| |
| 04:13 | <vagrantc> alkisg: it might be possible and a good idea, but we've got to make aboslutely sure that it doesn't accidentally trigger on a thin client, or accidentally not trigger on server ... although the latter case we get a fair amount of because people just use chroot directly
| |
| 04:14 | <alkisg> I googled for a "in_chroot()" function, and that code above seemed like a good approach
| |
| 04:15 | <vagrantc> if it didn't remove the LTSP_HANDLE_DAEMONS=false as a safeguard for those who do use it (or wrappers like ltsp-chroot that set it) i think it would probably be better than what we have now
| |
| 04:15 | <alkisg> And we can continue using LTSP_HANDLE_DAEMONS too, if in some cases it's impossible to detect if we're in a chroot
| |
| 04:15 | <vagrantc> good thinking :)
| |
| 04:15 | <alkisg> ^ that one
| |
| 04:15 | :)
| |
| 04:15 | cyberorg has left IRC (cyberorg!~cyberorg@opensuse/member/Cyberorg, Ping timeout: 258 seconds) | |
| 04:16 | <vagrantc> so i started using debootstrap --variant=minbase by default, and that turned up a few extra implicit dependencies
| |
| 04:16 | <alkisg> Cool, I'll test it as much as I can when I have some free time, and commit it without removing LTSP_HANDLE_DAEMONS
| |
| 04:16 | <vagrantc> namely, psmisc and such
| |
| 04:16 | alkisg: sounds great :)
| |
| 04:16 | <alkisg> Ah... did you put them in the ltsp-client-core package?
| |
| 04:17 | <vagrantc> not yet
| |
| 04:17 | but i had better eventually :)
| |
| 04:17 | also other things like rsyslog and who knows what else
| |
| 04:18 | i should just do two runs, one with minbase and one without, just installing ltsp-client-core, and see what the difference ends up being... if any are significant
| |
| 04:19 | but it's way simpler than the stupid outdated exclude list
| |
| 04:19 | and more proper anyways
| |
| 04:19 | cyberorg has joined IRC (cyberorg!~cyberorg@opensuse/member/Cyberorg) | |
| 04:19 | <alkisg> Another thing I'd like to propose in BTS, is to slowly move any permanent changes done to the chroot, from ltsp-build-client to the initramfs... that would make chroots directly bootable, nd package upgrades and even chroot upgrades safer...
| |
| 04:20 | So, no RC_WHITELIST (you removed that in Debian already),
| |
| 04:20 | ...and some other stuff I don't remember now. But it would require modifying more files while still in the initramfs
| |
| 04:21 | So either a longer bindwrite list (I don't remember the exact name), or nfs+tmpfs+aufs
| |
| 04:21 | How would you feel about that? (with the appropriate testing, backwards compatibility, etc etc?)
| |
| 04:22 | <vagrantc> i like the idea, as long as it doesn't consume too much extra memory
| |
| 04:22 | would be very cool to switch to nfs+tmpfs+aufs if it's reliable.
| |
| 04:23 | especially if it's also backportable
| |
| 04:23 | <alkisg> So I'm thinking of creating a /usr/share/ltsp/<scripts to be ran from the initramfs> directory, and to call that chrooted + with /proc, /dev etc mounted, from the initramfs
| |
| 04:23 | <vagrantc> alkisg: that's how i handled bindmounts and such from the initramfs
| |
| 04:24 | makes it much easier to respect lts.conf values properly and such
| |
| 04:24 | <alkisg> Cool. I would require a small change in other distro's initramfs's too, but I don't think it would be very troubling....
| |
| 04:24 | So if others agree too, I'd like to slowly start experimenting with that
| |
| 04:24 | <vagrantc> allows for a more full coding environment, too ... initramfs-only code tends to be rather restricted.
| |
| 04:25 | a shame i can't make it to the BTS
| |
| 04:25 | * alkisg would love to meet the old beard in person :( | |
| 04:26 | <vagrantc> heh
| |
| 04:27 | it would basically be 9-10 days, 6-7 of it travel... hard to finaggle the time
| |
| 04:27 | <alkisg> Or an (expensive) plane :-/
| |
| 04:27 | We should put that in the "needs sponshoring" list in the wiki ;)
| |
| 04:28 | * vagrantc tries to fly no more than one trip a year and only cross-continent | |
| 04:28 | <alkisg> Ah, k
| |
| 04:37 | * vagrantc tries to figure out if it would be at all remotely possible to go | |
| 04:39 | <alkisg> grep -l chroot /var/lib/dpkg/info/*inst ==> all those use the same "chrooted()" function, so it should be rather safe to add it ourselves
| |
| 04:53 | staffencasa has left IRC (staffencasa!~staffenca@128-193-148-203.oregonstate.edu, Ping timeout: 252 seconds) | |
| 04:56 | <alkisg> I don't quite doesn't get the (english language) meaning of `LTSP_HANDLE_DAEMONS="false"`... If we say "LTSP, don't handle daemons", wouldn't that mean "don't get involved, so exit 0"?
| |
| 04:58 | It sounds to me like LTSP_HANDLE_DAEMONS="true" would mean "LTSP, do handle the daemons; i.e. don't allow them to run"
| |
| 04:59 | <vagrantc> alkisg: think of it just HANDLE_DAEMONS, but specific to LTSP
| |
| 05:00 | <alkisg> Again, HANDLE_DAEMONS sounds like PREVENT_DAEMONS_FROM_STARTING to me, so if I didn't know, I'd think I'd have to set it to "true" to work
| |
| 05:02 | <vagrantc> it's not purty, it's true
| |
| 05:03 | <alkisg> So, if one does set LTSP_HANDLE_DAEMONS="true", I'll assume he doesn't want us to use the "autodetect chroot()" function
| |
| 05:03 | And directly `exit 0` instead
| |
| 05:09 | <vagrantc> well, i think i used != "false"
| |
| 05:11 | oh not, it's if it's "false", then don't start any daemons
| |
| 05:12 | <alkisg> Yes, so: if it's false, don't start any daemons
| |
| 05:12 | If the user hasn't set it, use chroot autodetection
| |
| 05:12 | Otherwise, exit 0
| |
| 05:12 | So if the user has set LTSP_HANDLE_DAEMONS="true", the chroot autodetection code won't be used
| |
| 05:13 | And the daemons will be started even if we're in a chroot
| |
| 05:13 | <vagrantc> why even have that
| |
| 05:13 | ?
| |
| 05:14 | <alkisg> No idea, but currently, with LTSP_HANDLE_DAEMONS="true" that's what happens... :)
| |
| 05:14 | OK I'll skip that
| |
| 05:14 | <vagrantc> essentially if LTSP_HANDLE_DAEMONS is not false, do what would normallly happen
| |
| 05:15 | so the in-chroot detection should also just exit 101
| |
| 05:16 | if [ "$L_H_D" = "false" ] ; then exit 101 ; elif in_chroot ; then exit 101 ; fi
| |
| 05:18 | ball has joined IRC (ball!~ball@c-50-129-25-121.hsd1.il.comcast.net) | |
| 05:18 | <vagrantc> or ... if [ "$L_H_D" = "false" ] ; then exit 101 ; fi ... #define the in_chooot() function ... if in_chroot ; then exit 101 ; fi
| |
| 05:18 | saves a little bit of codepath if the variable is set.

| 05:30 | <alkisg> OK so just this: http://paste.ubuntu.com/702076/
| |
| 05:34 | <vagrantc> so, the downside is every thinclient will make a bunch of stat calls whenever daemons are started
| |
| 05:35 | <alkisg> Unless we delete that from the initramfs ;)
| |
| 05:37 | <vagrantc> right!
| |
| 05:38 | ah, it was start-stop-daemon that i had the != "false" code in

| 07:37 | <Hyperbyte> mhmm
| |
| 07:38 | Someone here has brought a USB harddisk formatting with NTFS into the office
| |
| 07:38 | It mounts properly on the thin client as a local device, but it's mounted read-only
| |
| 07:38 | How can I make it so it gets mounted read-write?
| |
| 07:42 | <alkisg> Hyperbyte: if you manually try to mount it rw, does it work?
| |
| 07:43 | Ah, or when you say read-only, you mean that only root has write permissions for the ntfs partition?
| |
| 07:44 | What's the line for that mount in cat /proc/mounts ?
| |
| 08:11 | <Hyperbyte> What I mean is that none of the files/directories there have +w attribute set
| |
| 08:11 | And when writing I get the error "read/only filesystem"
| |
| 08:12 | One moment for mount options and manual mounting. Be back soon.
| |
| 08:14 | Hrm... it seems to already be mounted rw
| |
| 08:15 | Maybe it said read/only directory, not filesystem (I'm doubting myself now)
| |
| 08:15 | But mount options are
| |
| 08:15 | ltspfs on /media/inge/usbdisk-sda1 type fuse.ltspfs (rw,nosuid,nodev,user=inge)
| |
| 08:16 | But all file modes are 400 and directory 500. No write attributes set anywhere. Same happens when mounting locally on the client.
| |
| 08:22 | <alkisg> Hyperbyte: that's the default for ntfs, to mount it for the current user only
| |
| 08:22 | But since it's the root that mounts it, then the user doesn't have access
| |
| 08:22 | With ltspfs this shouldn't be a problem, as it runs as root, afaik
| |
| 08:23 | <Hyperbyte> So NTFS default is to mount it read-only?
| |
| 08:24 | <alkisg> No
| |
| 08:24 | <Hyperbyte> Because all owner/group bits are correct, those are set to the user that needs it, and their primary group
| |
| 08:24 | <alkisg> Ah, you said 400, not 700... hmmm...
| |
| 08:24 | <Hyperbyte> Yes...
| |
| 08:24 | There's no 'w' attribute anywhere on the filesystem
| |
| 08:25 | <alkisg> And the same happens if you try to mount it manually as rw?
| |
| 08:25 | <Hyperbyte> It is mounted as rw already
| |
| 08:25 | At least there is 'rw' in the mount options
| |
| 08:26 | When I manually mount it on the client, same thing. 'rw' in mount options, but all files and directories have read-only permissions
| |
| 08:27 | <alkisg> What ntfs package do you have installed?
| |
| 08:27 | dpkg -l '*ntfs*' | grep ^ii
| |
| 08:27 | Is it ntfs-3g ?

| |
| 08:30 | <alkisg> Ah then that's why
| |
| 08:30 | You need to install ntfs-3g for write support
| |
| 08:32 | <Hyperbyte> Just install ntfs-3g, that's it? No further configuration?
| |
| 08:34 | <alkisg> Yes, I believe so. And of course run ltps-update-image
| |
| 08:35 | <Hyperbyte> Of course!
| |
| 08:55 | That worked. :)

| |
| 09:56 | <Hyperbyte> The message has been received. :P
| |
| 09:56 | <txor> Hehe, sorry.
| |
| 09:56 | <Hyperbyte> You're gonna need to exercise some extreme patience for this one I think.
| |
| 09:56 | I know Gadi is the community-titled expert on things display related.
| |
| 09:57 | <txor> Yes It's onlt that I left the webchat and when I return I wanna see my message, plz don't be angry.
| |
| 09:57 | <Hyperbyte> You should try him if you can't get an answer from someone else. Also, it might help to make a screenshot. :)
| |
| 09:57 | No, I'm not angry at all. =)
| |
| 09:57 | Also, you can read channel logs at http://irclogs.ltsp.org/
| |
| 09:58 | <txor> Where or how I can debug gnome problems? It's possible to connect an X client to the LTSP sever without booting nothing? Only X client from other system? That might help me
| |
| 09:59 | Hyperbyte: I go to the logs to copy my message, correct the rendered word, add the "Sorry for posting twice" and let my message appear on the top of my IRC client :P
| |
| 10:00 | <Hyperbyte> Hahaha
| |
| 10:00 | txor, LTSP uses remote X
| |
| 10:01 | It's probably some problem with the kernel module for your GPU in combination with remote X
| |
| 10:01 | You could try
| |
| 10:01 | !disable-compiz
| |
| 10:01 | <ltsp> Hyperbyte: disable-compiz: To disable compiz for all users, run: sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type string --set /desktop/gnome/session/required_components/windowmanager metacity

| 10:01 | I'm just not knowledged enough in these things to -really- say what the problem is. =)
| |
| 10:02 | <txor> Hyperbyte: Compiz is uninstalled, I use metacity. I was trting with lts.conf options about configuring xorg.conf but sometimes I can't change the xorg.conf
| |
| 10:03 | Hyperbyte: I agree with you about It's a GPU driver + X11 config problem, and maybe some Gnome lib version
| |
| 10:04 | But... I have no idea on how to attack the problem. Mayb I have to ask Gnome devels to see which parts are rendering the icons... Do you want to see an screenshot?
| |
| 10:10 | <Hyperbyte> Screenshot might be interesting, sure.
| |
| 10:10 | But like I said, I'm not really the person to help you with this.

| |
| 13:07 | I grabbed a zipped chroot from a fedora host and put it in /opt/ltsp
| |
| 13:08 | <Hyperbyte> Zipped?
| |
| 13:08 | <jason_> updated the kernels, ssh keys, etc
| |
| 13:08 | compressed
| |
| 13:08 | tar.gz2
| |
| 13:08 | <Hyperbyte> gzipped, okay
| |
| 13:08 | I thought you meant literally 'zipped', because I doubt that'd work.
| |
| 13:08 | <jason_> sorry, windows terminology sometimes crosses over
| |
| 13:08 | <Hyperbyte> Hehe
| |
| 13:08 | <jason_> I work with all platforms throughout the day. :/
| |
| 13:08 | I changed the pxe config to what I saw on the ubuntu crossarch page.
| |
| 13:08 | but the ibook I'm using just sits here and loops and eventually boots to osx
| |
| 13:09 | <Hyperbyte> I'm confused.
| |
| 13:09 | Show me the Ubuntu crossarch page?
| |
| 13:09 | <jason_> https://help.ubuntu.com/community/UbuntuLTSP/LTSPCrossArchSetup
| |
| 13:10 | <Hyperbyte> Okay
| |
| 13:10 | Now you say, it sits there looping
| |
| 13:10 | When does it stop exactly?
| |
| 13:10 | <jason_> yes
| |
| 13:10 | <Hyperbyte> Does it even -try- a network boot, or does it just not network boot at all?
| |
| 13:10 | <jason_> It sits there for a rather long time, flashing with the network icon.
| |
| 13:10 | It appears as if it's trying.
| |
| 13:11 | yesterday I saw a DHCP lease show up in the leases config.
| |
| 13:11 | So it looked like it grabbed an IP
| |
| 13:11 | <Hyperbyte> There are two stepts.
| |
| 13:11 | <jason_> I've just got it hooked up with a cat5 cable, directly
| |
| 13:11 | <Hyperbyte> *steps
| |
| 13:11 | 1. Obtaining network address
| |
| 13:11 | 2. Downloading TFTP image
| |
| 13:11 | I want the exact error before it loops
| |
| 13:12 | If it fails at step 1, your DHCP server isn't handing out leases
| |
| 13:12 | <jason_> macs don't show the details like PCs do as they boot
| |
| 13:12 | all I see is a flashing icon
| |
| 13:12 | <Hyperbyte> Oh
| |
| 13:12 | <jason_> I don't see the pxe config load
| |
| 13:13 | however, I did get a lease
| |
| 13:13 | <Hyperbyte> That's handy.
| |
| 13:13 | <jason_> no kidding
| |
| 13:13 | <andygraybeal> greetings Hyperbyte :)
| |
| 13:13 | <Hyperbyte> Hey Andy!
| |
| 13:13 | <jason_> it's just a crappy situation to be in
| |
| 13:13 | <m4xx> i'm trying to setup a pxe boot menu so i can choose between desktop mode and kiosk mode. I've followed along with: http://www.serenux.com/2010/05/howto-setup-your-own-pxe-boot-server-using-ubuntu-server/ but i end up with the error: "could not find kernel image: ubuntu-installer/i386/boot-screens/vesamenu.c32"
| |
| 13:13 | <Hyperbyte> How long does it loop for?
| |
| 13:13 | Does it loop quickly, or does it sit for a few minutes?
| |
| 13:13 | <jason_> because these old macs. yes. they're pretty bad. but they turn on and they're functional. so it's hard to just throw them out if we CAN utilize them as clients...
| |
| 13:13 | <m4xx> it does exist in my tftp directory and is readable
| |
| 13:15 | <jason_> its a steady flash of the network icon, indicating it's trying. It stays there for about 3 full minutes.
| |
| 13:15 | then OSX just takes over.
| |
| 13:15 | it reminds me of issues I had in the past where the image wouldn't come down, yet I got an IP
| |
| 13:17 | I know that PPC and Linux is turning into more of a joke every day but if I can get them running it'd be pretty awesome...
| |
| 13:17 | however documentation (and even confirmation that anybody out there has a full blown working setup) seems few and far between
| |
| 13:17 | if at all
| |
| 13:18 | <alkisg> How many of them do you have?
| |
| 13:18 | <Hyperbyte> jason_, I think you can probably learn more by doing a tcpdump. You can see on the server side if it gets a lease, and what exactly it requests from the TFTP server.
| |
| 13:19 | <jason_> Hyperbyte: how's that work? run tcpdump in terminal and netbook the mac?
| |
| 13:19 | boot*
| |
| 13:19 | <Hyperbyte> tcpdump --help
| |
| 13:19 | You'll probably want something like tcpdump -i <iface>
| |
| 13:20 | But, this'll generate a constant stream of data if you're connecting to the server via network
| |
| 13:20 | <jason_> by the way... I AM getting a lease
| |
| 13:20 | <Hyperbyte> You can only do this if the server isn't generating other network traffic.
| |
| 13:20 | <jason_> I can see that in the dhcp3.leases file
| |
| 13:20 | <Hyperbyte> You have a Fedora server, correct?
| |
| 13:20 | <jason_> ubuntu
| |
| 13:21 | <Hyperbyte> Okay. Check /var/log/syslog for tftp messages.
| |
| 13:21 | Or better yet
| |
| 13:21 | tail -f /var/log/syslog
| |
| 13:21 | And boot the Mac, see if anything appears
| |
| 13:21 | (-f follows the file updates)

| 13:23 | <Hyperbyte> Hrm
| |
| 13:23 | <jason_> every once in a while dhcpinform and dhcpack runs
| |
| 13:23 | <Hyperbyte> Okay
| |
| 13:23 | Show your dhcpd.conf
| |
| 13:23 | <jason_> you want a pastebin ?
| |
| 13:24 | <Hyperbyte> Yes please?
| |
| 13:24 | <jason_> k. I just wasn't sure if that's what you were asking :P
| |
| 13:24 | let me swap this on the main network quick...
| |
| 13:25 | <m4xx> whoops
| |
| 13:26 | i miss-read i put the ubuntu-installer directory in pxelinux.cfg instead of my root directory
| |
| 13:27 | <jason_> ultra slow internet today...
| |
| 13:29 | http://pastebin.com/5Yra7m0N
| |
| 13:30 | I tried two different ways. I had copied my config file directly from the ubuntu crossarch site and I also just replaced all instances of i386 with ppc
| |
| 13:30 | both did nothing
| |
| 13:32 | <Hyperbyte> Right. Before you said you got a copy of a Fedora chroot, right?
| |
| 13:32 | <jason_> https://fedorahosted.org/k12linux/wiki/PPCClientHOWTO
| |
| 13:33 | <Hyperbyte> Right. But I'm a bit confused.
| |
| 13:33 | You're using Ubuntu as server, correct?
| |
| 13:33 | And you're gonna do this with a Fedora chroot?
| |
| 13:33 | <jason_> yes
| |
| 13:33 | I was told the chroot is the same regardless
| |
| 13:33 | <Hyperbyte> Who told you that?
| |
| 13:33 | <jason_> I read it somewhere. a mailing list perhaps?
| |
| 13:34 | that the chroot was rather agnostic to the platform
| |
| 13:34 | that's why I didn't give it too much thought with fedora hosting this
| |
| 13:34 | <Hyperbyte> Probably right... mmm...
| |
| 13:34 | Fedora and Ubuntu implementation of LTSP is quite different (NFS vs NBD) but that's all done outside the chroot I think.
| |
| 13:35 | <jason_> I'm going to swap my dhcp over to what I found on the ubuntu site. I see that dhcp config has a yaboot entry required for mac.
| |
| 13:35 | but I did this yesterday and it failed, however, I also did that from the actual powerpc "server" I was testing
| |
| 13:35 | now I'm on an intel server
| |
| 13:35 | doubt it'll make any difference...
| |
| 13:35 | <Hyperbyte> Are you trying this with NFS or NBD?
| |
| 13:36 | <jason_> uh. how do I tell? It's just a vanilla edubuntu install
| |
| 13:36 | <Hyperbyte> Okay.
| |
| 13:36 | Then you're mixing up Fedora and Ubuntu instructions and failing there.
| |
| 13:36 | <jason_> sigh :(
| |
| 13:36 | <Hyperbyte> I can help you.
| |
| 13:36 | But... two conditions.
| |
| 13:36 | 1. I need to finish some of my own work first.
| |
| 13:37 | 2. I want root@yourserver
| |
| 13:37 | <jason_> hahah
| |
| 13:37 | well
| |
| 13:37 | @ 1, of course
| |
| 13:37 | <Hyperbyte> Or screen sharing or whatever.
| |
| 13:37 | <jason_> @ 2, I'm not sure I can do that on this network...
| |
| 13:37 | worth a shot I suppose
| |
| 13:37 | <m4xx> ls
| |
| 13:37 | oops
| |
| 13:37 | <Hyperbyte> Well, 2, that's your prerogative. :) I just wanna poke around the filesystem, look at the config, etc... without continually asking for pastebin.
| |
| 13:38 | <jason_> it's not a matter of whether or not I want to
| |
| 13:38 | it's a vailla server. I have no quarrel with that.
| |
| 13:38 | I'm just not sure the outside is opened up that far
| |
| 13:38 | because we don't fully control this network
| |
| 13:38 | we pipe through a college before we go external
| |
| 13:38 | from what I've seen so far it's pretty locked down, which is my only concern
| |
| 13:38 | <Hyperbyte> You can do reverse connections, but MY network isn't set up for that.
| |
| 13:38 | What timezone are you in?
| |
| 13:38 | <jason_> eastern
| |
| 13:39 | <Hyperbyte> Right, America.
| |
| 13:39 | Or not?

| 14:38 | <stgraber> ogra_: so do you have your flights booked for BTS+UDS?
| |
| 14:38 | <ogra_> stgraber, nope
| |
| 14:39 | <stgraber> ok :)
| |
| 14:39 | <m4xx> alkisg: still no go =[
| |
| 14:39 | <ogra_> but given i have working images and not much to do but stare at bugs, i should probably do it now :)
| |
| 14:39 | <stgraber> ogra_: I guess that'd be a good idea ;)
| |
| 14:40 | * ogra_ goes to dig up the dates | |
| 14:40 | <m4xx> i already had the file, i also killed my chroot, re-created it and added the files

| 14:42 | <alkisg> m4xx: search the irc logs for kiosksession, I think the problems with kiosk that lucid has have been mentioned about 10 times
| |
| 14:42 | It's not only the kiosksession file, you also need to apply a patch if I remember well
| |
| 14:43 | Unfortunately no devs actually use the kiosk plugin, so it's not actively maintained

| 14:50 | <m4xx> i see your convo with _UsUrPeR_, looks like he had gotten it working with out having to patch and taking the steps you had suggested from the bug report.
| |
| 15:01 | <alkisg> m4xx: if you read all the conversation, you'll see that he needed both the kiosksession file and the xargs workaround
| |
| 15:02 | <m4xx> i've done both
| |

| 15:03 | <ltsp> alkisg: SCREEN_02: to get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using%20a%20shell%20SCREEN
| |
| 15:03 | <m4xx> did that and i get a blank screen
| |
| 15:03 | no prompt
| |
| 15:03 | <alkisg> Errm...
| |
| 15:03 | <m4xx> i've just set a root password
| |
| 15:03 | and updated the image
| |
| 15:03 | about to just login on screen 1
| |
| 15:04 | <alkisg> OK, that's good too. Run a `ps aux > /tmp/out; scp /tmp/out user@server` and pastebin the output of ps

| |
| 15:07 | <alkisg> Another one with kiosk problems - your turn :D :
| |
| 15:07 | <_UsUrPeR_> okay
| |
| 15:07 | <alkisg> (hi!)
| |
| 15:07 | <_UsUrPeR_> I have a question for you after, alkis
| |
| 15:08 | <m4xx> http://pastebin.com/UE9qMnxF
| |
| 15:08 | <alkisg> Sure
| |
| 15:08 | * _UsUrPeR_ reads above | |
| 15:09 | <alkisg> m4xx: from the same root shell, try: getltscfg -a
| |
| 15:09 | And check that SCREEN_07 is indeed kiosk
| |
| 15:09 | Because now you're just using ldm
| |
| 15:09 | <_UsUrPeR_> m4xx: I think I have a lts.conf for you
| |
| 15:10 | <m4xx> one sec i'll paste mine
| |
| 15:10 | <_UsUrPeR_> this is something I set up to run in X, straight-up. no gnome
| |
| 15:10 | it may not specifically apply
| |
| 15:11 | <m4xx> http://pastebin.com/x2Jt50bR
| |
| 15:13 | <alkisg> m4xx: and does `getltscfg -a` have the same values too?
| |
| 15:13 | <m4xx> sorry phone
| |
| 15:13 | one sec
| |
| 15:14 | <alkisg> It seems to me that your lts.conf isn't being read
| |
| 15:15 | <m4xx> you are correct sir
| |
| 15:16 | <alkisg> Is that in /var/lib/tftpboot/ltsp/i386/lts.conf ?
| |
| 15:17 | <_UsUrPeR_> interesting
| |

| |
| 15:22 | =]
| |
| 15:22 | not sure what the hell did it, but it works =]
| |
| 15:23 | thank you very much
| |
| 15:24 | <_UsUrPeR_> no problem
| |
| 15:24 | check the kiosk_exe command
| |
| 15:24 | alkisg: ok, so here's the deal
| |
| 15:24 | now that we have fixed m4xx's problem...
| |
| 15:25 | I am running iceWM. It turns out that when you shut off/close/log out of a session in icewm, it does not clear user processes. They just sit there.
| |
| 15:25 | I am trying to find something on the server side that will execute upon login so I can kill the user's old session/processes
| |
| 15:26 | right now, I am attempting to test a theory using /etc/X11/xinit/xinitrc. The exact line I have added is "killall -u $USER"
| |
| 15:26 | it doesn't seem to take effect like I would have expected
| |
| 15:27 | NOW, I am making changes to the startx script
| |
| 15:28 | though I am not sure if icewm is called with startx :/
| |
| 15:28 | called/started, that is
| |
| 15:28 | <m4xx> last question, when you get a chance. i've set up a pxe boot menu to choose between kiosk and desktop mode. is there any way i could define the screen variable with that menu too? or could i use it to select which lts.conf to use?
| |
| 15:29 | <_UsUrPeR_> m4xx: I have never actually used a pxe boot menu before, so I am not sure about that one
| |
| 15:30 | <alkisg> !xexit | echo _UsUrPeR_:
| |
| 15:30 | <ltsp> _UsUrPeR_: xexit: Instead of gnome-watchdog one can use xexit, which is a similar (but better!) tool written by an LTSP developer: http://www.opinsys.fi/en/killing-user-processes-with-xexit-on-ltsp-servers
| |
| 15:31 | <_UsUrPeR_> alkisg: :O
| |
| 15:34 | <alkisg> m4xx: you can pass a kernel parameter and then create a script in $ROOT/usr/share/ltsp/ltsp_config.d that greps /proc/cmdline for it, and sets SCREEN_07 appropriately
| |
| 15:34 | !ltsp_config.d
| |
| 15:34 | <ltsp> alkisg: Error: "ltsp_config.d" is not a valid command.
| |
| 15:36 | <alkisg> !learn ltsp_config.d as You can create /opt/ltsp/i386/usr/share/ltsp/ltsp_config.d/ and put scripts in it that dynamically set lts.conf variables. Those scripts are sourced by LTSP, not executed.
| |
| 15:36 | <ltsp> alkisg: The operation succeeded.
| |
| 15:36 | <_UsUrPeR_> alkisg: how do you remember these !commands? :)
| |
| 15:36 | <alkisg> !kiosk
| |
| 15:36 | <ltsp> alkisg: I do not know about 'kiosk', but I do know about these similar topics: 'kiosk-lucid'
| |
| 15:37 | <alkisg> There's no need to remember them all ;)
| |
| 15:37 | They're even searchable

| |
| 16:18 | correct?
| |
| 16:22 | <alkisg> In pxelinux.cfg: "append initrd... kiosk"

| |

| |

| 17:00 | <_UsUrPeR_> ooooooook
| |
| 17:01 | a question about program versions and the apt repositories: let's say that I want to download a specific, non-current version of a program once available on apt
| |
| 17:01 | <obrienmd> alkisg: regarding your advice yesterday to use 'nbdroot=server:1.2.3.4 NBD_ROOT_NAME=devname' or 'nbdroot=server:1.2.3.4 nbdname=devname', neither worked... I ended up giving up and using the old device-per-port method in nbd-server config, and traditional nbdroot=1.2.3.4:10809 in pxelinux.cfg
| |
| 17:01 | <_UsUrPeR_> where would I go to do that?
| |
| 17:07 | <alkisg> obrienmd: nbdroot=server:port, not server:ip. But ok if you got it working... ;)
| |
| 17:07 | _UsUrPeR_: if it's still available in the archives, it's: sudo apt-get install program=version
| |
| 17:08 | <_UsUrPeR_> alkisg: ok, let's say... it's not
| |
| 17:08 | just for instance
| |
| 17:08 | <obrienmd> alkisg: yeah, I was trying to setup using server IP and device name only on oneiric, just going over standard port 10809
| |
| 17:08 | 'new sty;e' :)
| |
| 17:08 | <alkisg> _UsUrPeR_: Well then you need to manually download it from the net and install it with gdebi or dpkg -i
| |
| 17:09 | obrienmd: Yes I remember, but above you wrote: nbdroot=server:1.2.3.4, which wouldn't work in any case
| |
| 17:09 | While nbdroot=server:10809 NBD_ROOT_NAME=opt... might work
| |
| 17:10 | Not sure if the new initramfs exposes variables with capitals from the command line, though
| |
| 17:16 | <obrienmd> ah I see, will take a shot at that
| |
| 17:17 | thanks again
| |
| 17:17 | unfortunately I can only test this in about a 15m window each night :)

| 20:08 | <m4xx> i feel quite helpess today =[ How would I install a firefox plugin in a chroot? I've tried installing the plugin, then copying the .mozilla directory to /opt/ltsp/kiosk/usr/local/share/ltspkiosk/home and re-building the image but that didn't seem to make any effect.
| |
| 20:10 | <vagrantc> m4xx: you're using localapps or fatclients?
| |
| 20:10 | with thin-clients, you would just install on the server.
| |
| 20:10 | <m4xx> it's a kiosk chroot, i think it's localapps
| |
| 20:10 | <vagrantc> ah, yes.
| |
| 20:11 | mozilla products weren't really designed with multi-user systems in mind... *sigh*
| |
| 20:11 | <abeehc> frown
| |
| 20:13 | <vagrantc> so copyying the .mozilla doesn't tend to work so well ... it isn't a plugin available via apt-get?
| |
| 20:13 | <m4xx> no
| |
| 20:13 | not that i saw
| |
| 20:13 | r-kiosk
| |
| 20:14 | <vagrantc> it's generally not too difficult to package a plugin... if you're at all familiar with packaging.
| |
| 20:14 | <abeehc> for thunderbird localapps extensions i put the extension folder in usr/lib/thunderbird/extensions
| |
| 20:15 | of chroot, or server for that matter
| |
| 20:16 | i imagine similar thing applies for ff but the folder can be slightly different; you should find the language extension in whatever folder though
