<hughessd>
im just about to try booting the HP thinclient from a USB to see if that will give me any new info. great idea.
01:24
<vagrantc>
it at least might allow us to point a finger at ubuntu rather than LTSP :)
01:24
<hughessd>
hah :)
01:30
unfortunately, the HP thin client seems to be fine. the display is coming up and actually refreshing this time....
01:30
even got to 1920x1080

hm.
01:34
wonder what LTSP is doing differently, then.
01:35
gotta roll, but there are lots of good folks who can hopefully help troubleshoot!
01:39
<hughessd>
no worries. data collecting now.
01:40

i want to allow localapp use direct rendering - is there easy way for this?
06:27
it's look like user that created on client side not member of "video" group
06:27
and problem in this

<alkisg>
alexqwesa: when you enable localapps, all the groups that the user belongs on the server are transferred to the client, so if he's on the video group on the server, he should be on the client too

Hi folks: running into weird problems updating my ltsp image which dontshow up on normal workstations. If time have a look here: http://pastebin.com/Yd8uYsHR

<muppis>
piet, you have grub installed for nothing. You can skip that error adding exit 0 to begin of /usr/sbin/grub-probe because removing grub can screw your chroot.

piet: sudo mount --bind /dev /opt/ltsp/i386/dev, before running the ltsp-chroot -otherparameters

That's included in latest versions of ltsp-chroot

<piet>
thanx folks for adhoc answer . . .
12:50
@alkisg: this just makes the dev viewable under ltsp-chroot, but it doesnt solve the problem, right? (pls folks be patient with a noob :)
12:52
@muppis: Im not that stable in using terminal so what does /usr/sbin/grub-probe to me (my installation) and how do I get rid of that stuff? In chroot <apt-get purge grub>?
12:52
<alkisg>
piet: the prob is this: /usr/sbin/grub-probe: Fehler: cannot find a device for / (is /dev mounted?).
12:52
If /dev is "viewable under the chroot", then grub-probe will work
12:54
<piet>
@alkisg: so in short 1)gochroot 2 with dev viewable and 2) /usr/sbin/grub-probe and prob will be gone. Did I get this right?
12:54
<alkisg>
piet: yes, but not only /dev, use the other ltsp-chroot options for mounting /proc etc too
12:55
(02:44:44 μμ) alkisg: piet: sudo mount --bind /dev /opt/ltsp/i386/dev, before running the ltsp-chroot -otherparameters
12:56

@alkisg ok sure . . . BTW is there a chance to send You a private mail - got some honest surprise for U?

<alkisg>
Hi Hyperbyte
12:59
<Hyperbyte>
alkisg, I just hope he keeps his clothes on
13:00
Hi alkisg!
13:00
;-)
13:00* alkisg isn't afraid much over the wire... up close, I might be :P
13:00
<Hyperbyte>
Well, he's closer to me than to you
13:00
So as long as he doesn't want my private e-mail address....
13:01
Oh hey - cool story - true story!
13:01
I was baking some bread yesterday in the oven... and when I went to grab it when it was done, my hand hit the top of the oven
13:01
*ssssss*
13:02
It seriously smelt like burnt bacon or something...
13:03
<alkisg>
Ououououch that hurt even over the wire :P
13:05
<Hyperbyte>
Yeah, I was telling my collegue over lunch and he didn't want to eat anymore.
13:06
<elias_a>
Glad to see the atmosphere on this channel is the same even if I have been away with my lousy stories for a while :)
13:06
<Hyperbyte>
Hahah
13:06
Hey elias_a. :-)
13:07
<elias_a>
Sorry, dudes - been in a difficult situation and exhausted for a while.
13:07
Now I'm idling here again :)
13:08
<Hyperbyte>
Difficult situation?
13:08
Have a seat on our couch...
13:08
<muppis>
Hit byt steam of egg boiler: http://m.muppis.net/20120213_091445.jpg
13:08
<Hyperbyte>
Tell us about it.
13:09
Ah muppis that's nothing. With my burn you still see a little bit of scorched edges, on the side of the gaping whole where once was skin.
13:12
(I'm not creeping you guys out too much, am I?)
13:15
<elias_a>
Hyperbyte: Nothing to tell anymore. Death in family. Pancreatic cancer.

Hyperbyte, I can figure. My burn was just made by a steam, and not even pressured one. It didn't hurt then, but it is a pain because of it location in my arm, just near of wrist.
13:38
<mgariepy>
good morning everyone
13:38
<alkisg>
Good morning mgariepy
13:40
<muppis>
Good afternoon.
13:42
<mgariepy>
alkisg, i was scrolling up in the history and nbd-proxy only need <server> <port_to_connect_on_server> <port_to_accept_connection>
13:42
<alkisg>
mgariepy: I pushed a helper script for you to use
13:42
I only know that much about proxy, if it doesn't work you'd need to explain more to me to fix it
13:42
<Hyperbyte>
elias_a, ah, sorry to hear that... someone very close to you?
13:43
<alkisg>
mgariepy: http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/revision/2046
13:43
So, you need to pass NBDCLIENT=nbd-client-proxy in the command line to use it
13:43
Check the commends in the code as well, if you need anything I'm here
13:44
<mgariepy>
ok cool.
13:51
ltsp-update-image doesn't seem to work anymore
13:52
<andygraybeal>
aahgh gross muppis
13:53
Hyperbyte, that's diusgusting!
13:55
<alkisg>
mgariepy: using the latest trunk? Any error messages?
13:55
<andygraybeal>
i should show you guys pics of when i flay my fingers :)
14:01

alkisg, bzr diff -r 2040..2041
14:12
<andygraybeal>
er wrong channel
14:15
<alkisg>
mgariepy: yes, the default BOOT line isn't needed anymore, we're using the stock nbd initramfs script which uses the default BOOT=local
14:15
<mgariepy>
i guess that we can only test if the file exist ?
14:16
or whatever you think is better.
14:16
<alkisg>
mgariepy: sorry I didn't understand the problem, could you elaborate?
14:17
<mgariepy>
ltsp-update-image grep for nbd in /opt/ltsp/new//usr/share/initramfs-tools/conf.d/ltsp
14:18
line 315 of ltsp-update-image
14:18
<alkisg>
Ah, right, and I hit that in the past and I forgot to update it
14:19
Let me see the code again...
14:28
<mgariepy>
stgraber, shouldn't the pae kernel be installed by default in the chroot ?
14:29
<stgraber>
mgariepy: depends on how you're installing LTSP and which version you're using exactly
14:29
<mgariepy>
precise + experimental ppa ;)
14:30

14:36
<stgraber>
mgariepy: ah, no, sorry, you should get the non-pae kernel, if you get pae, that's a bug ;)
14:37
(which we have currently in the non-PPA version ;))
14:37
<mgariepy>
kk
14:39
<alkisg>
mgariepy: the new chroots will be bootable with nfs and nbd without changes, except for the kernel command line
14:40
So that check in ltsp-update-image doesn't make much sense
14:40
If some check needs to be made anyway, check if -f $CHROOT/usr/share/initramfs-tools/scripts/local-top/nbd
14:40* alkisg needs to go for a few hours...

For ltsp in a educational enviroment? Would edubuntu be a good choice for a LTSP server or should I just start with Ubuntu and go forward?
16:26

Edubuntu would be an easier way with all the package already installed

also i changed init-ltsp.d/common/00-kernel-cmdline to fix a issue generated from moving from busybox to dash
17:22
<alkisg>
Good catch
17:23
I'm thinking of removing support for "NFS_HOME", "NFS_HOME_OPTIONS" etc, and just add support for FSTAB_00 to 99.

It currently doesn't work with the new system, it's called too soon. I can move it to ltsp-client-core, but I think it'd be better to just put it to fstab and let the system handle it
17:25
<mgariepy>
yeah i guess that make sense too. this way we could mount something fancy
17:27
<stgraber>
uploaded a new ltsp package, previous one failed as I forgot to remove nbd-update-config...

@alkisg: surprise is on the run. . . There is still an open Question. I was successful to get into the chroot with <mount /dec. . .> and <ltsp-chroot -pcd> but I dont get the point how <grub-probe> could help me to solve the problem. . . .
17:49
<alkisg>
Hi piet, I got the email, thank you. Run apt-get dist-upgrade in the chroot, that should finish all the pending package installations...
17:50
1) sudo mount --bind /dev /opt/ltsp/i386/dev
17:50
2) sudo ltsp-chroot -all-the-mounting-options-dont-remember-them /opt/ltsp/i386
17:50
apt-get update
17:50
apt-get dist-upgrade
17:50
exit
17:51
sudo umount /opt/ltsp/i386/dev
17:51
and you should be then ready to call ltsp-update-image etc
17:52
<piet>
@alkisg: I know, what U mean, but I think in my last test, the problem persited . . . but wait a minute I try it again . . .
17:57
@ akisg: yes, it looks like as if it works. I still dont know, what I did wrong, because I never installed grub exlicitly. I only updated like I should . . .
17:57
<alkisg>
Grub is installed by the ubuntu-desktop package, it's normal for fat clients to have it installed
17:57
<piet>
Does it have something to do with standart kernel updates?
17:59
<alkisg>
ltsp-chroot has been updated to support mounting /dev too
17:59
So it won't be much of a problem in the future
17:59
<piet>
@alkisg: ahhh I misunderstood the other guy telling me grub doesn't belong there . . .
17:59
but most probabely he didn't know I was using fat.
17:59
<alkisg>
It's not useful, sure, but it shouldn't hurt to have it there
17:59
No no what he was saying made sense,
18:00
it would just come back on kernel upgrades and trouble you again
18:00
So you either mount /dev, as you do now, or blacklist the grub package, which is harder
18:02
<piet>
ok. BTW I did nearly everything to get local hdds to be mounted on the fat client. I read that I have to use a tool to give rights to a user to see his locals, but it was not mentioned which one. Do U have an idea?
18:04
<alkisg>
piet: the user needs to be in the admin group to be able to mount local disks, afaik
18:04
Otherwise you'd need to edit the chroot policykit settings
18:05
<piet>
@alkisg there was something mentioned about fuse?
18:05
<alkisg>
That's for ltspfs and thin clients and older versions of ubuntu
18:05
I.e. not related to fat clients
18:06
<piet>
@ alkisg is there an ltsp.conf - way/parameter to manage this generally/stationwise like with sshfs-mounts?
18:07
we had that in gentooly and that was very comfortable . . .
18:09
<alkisg>
Well, if you want to do it with an indirect way, you can put DENY_INTERNAL_DISKS=False or something similar, not sure about the name
18:09
I have to do some work on ltsp though because tomorrow there's a deadline, so I"ll be more available the day after tomorrow, for the epoptes wiki page too
18:10
<piet>
where do U get all these paras from? Is there a dok around?
18:10
<alkisg>
!lts.conf
18:10
<ltsp>
alkisg: lts.conf: http://manpages.ubuntu.com/lts.conf
18:10
<alkisg>
LOCALDEV_DENY_INTERNAL_DISKS boolean, default True
18:10
So you set that to false

I think the trunk was silent lately except for us here in #ltsp, so I guess it won't be a problem for a while
18:36
<stgraber>
I guess vagrant will agree too and I know where mgariepy lives so for these two it should be fine
18:36
I'm just hoping nobody from Gentoo/Fedora pushes new non-distro-specific features
18:36
<mgariepy>
lol
18:37
<alkisg>
knipwim, so if you have any cool new features, please push them within 20 hours or after 20 days :D
18:37
<mgariepy>
i just wan't it to work, i don't really need new feature for now ;)
18:38
<alkisg>
Indeed, I wasn't expecting the move to the init-ltsp.d in precise
18:38
I thought it was going for 12.10
18:38
Otherwise all that would have been stabilized months ago...
18:39
So now we only have time for bug fixes actually... e.g. NFS_HOME not working, so switch to FSTAB_xx, shutdown not working, so create upstart jobs, etc etc
18:40
<knipwim>
alkisg: i'm experimenting with the ltsp-client boot from initramfs
18:40
but no commits will occur for a long time
18:40
<alkisg>
Bug fixes are ok, new features are a problem
18:41
<knipwim>
new features how?
18:41
<alkisg>
E.g. the move to ltsp-init.d was a new feature
18:41
Or the move to nbd-server's conf.d
18:41
<mgariepy>
alkisg, when i exit ltsp-chroot -p -a new i got errors:umount: /opt/ltsp/new/proc/sys/fs/binfmt_misc: not mounted
18:41
Couldn't unmount /opt/ltsp/new/proc/sys/fs/binfmt_misc.
18:41
<alkisg>
While SCREEN_07 not defaulting to "ldm' was a bugfix
18:41
<knipwim>
like changes which affect ltsp for all distro's
18:42
<alkisg>
Right
18:42
mgariepy: let me check the code..
18:44
<knipwim>
alkisg: so would it be oke to commit changes which only affect gentoo behaviour?
18:44
<alkisg>
I think so, stgraber? ^
18:46
mgariepy: I can't reproduce it, do you have anything mounted in the chroot when you issue the ltsp-chroot command?
18:46
<knipwim>
and unless free time will magically appear, i won't commit any in the coming 20 days
18:47
alkisg: mgariepy: proc/sys/fs/binfmt_misc doesn't get mounted by ltsp-chroot
18:47
<alkisg>
knipwim: if you install e.g. wine in the chroot, the postinst mounts that
18:48
So it needs to be unmounted for a clean ltsp-update-image afterwards
18:48
<mgariepy>
nop i just do ltsp-chroot -p -a new
18:50
<alkisg>
mgariepy: can we share a screen? either `screen` or `x11vnc`? No port forwarding needed...
18:50

18:51

"The goal for Ubuntu 12.10 is to basically have the ltsp-client packages installed by default on Edubuntu, allowing to simply export our install media as a fat chroot, so no more shipping chroots and building chroots (for the most common cases)." ==> yey!

Hi! I need help :(. My ltsp machines stopped booting. It's a Ubuntu installation, and they just hang before launching ldm

I have tried lots of things, without success
19:30
console and X are dead, but I can log via ssh
19:31

semuaa, I'm gonna take a wild guess here
19:31
!update-sshkeys

19:31
<Hyperbyte>
!ltsp-update-sshkeys
19:31
<ltsp>
Hyperbyte: ltsp-update-sshkeys: If you changed your server IP, you need to run ltsp-update-sshkeys, and if you're using NBD (Ubuntu) you also need ltsp-update-image afterwards
19:32

I'm using LTSP 5 with Ubuntu 10.04
21:09
I'd like to install virtualbox in fat client
21:09
I go in chroot, then apt-get install virtualbox
21:10
after i do a ltsp-update-image and reboot
21:11
but when i launch a VM it tells me to do a /etc/init.d/vbxdrv setup
21:11
I did it !! But it doesn't work
21:11
Have you tired it ?
21:17
<kleewyck>
make sure your networking is bridged not nat for the virtual box.
21:17
you also have to install the virtual box extensions to have pxe boot
21:18Parker955 is now known as Parker955_Away
21:24
<ninipote>
I explain : when i use a client (via pxe boot), i try to open virtualbox. I've got the error : "/etc/init.d/vboxdrv setup" and the VM doesn't start.
21:25
So i sudo on the fat client : "/etc/init.d/vbxdrv setup" ; i take 30 seconds and after i reload virtualbox and the VM and it's working !

22:43
<vagrantc>
haven't had a chance to read mail yet
22:43
<alkisg>
I'm replacing NFS_HOME with FSTAB_0 to FSTAB_9, complete lines to go to lts.conf. That will even allow local home mounting with UUID, LABEL etc. I'm putting some NFS_HOME backwards compatibility code though.
22:43
<vagrantc>
stgraber: so a little under 24 hours?
22:44
nice.
22:44
<alkisg>
vagrantc: if you have some time to check which of the init-ltsp.d/Ubuntu files also belong under common/, it'd be nice
22:44
<vagrantc>
i'd like to tidy up a few things, but if i don't get around to it, no big deal.
22:44
alkisg: it's hard for me to say what belongs in common, some things i'd definitely want to borrow for Debian, though
22:47
<alkisg>
Ah, and another thing, I'll be putting some shutdown and restart upstart jobs to close the nbd and ssh connections before issuing "echo o > sysrq" for instant shutdown / reboot, maybe I should make them sysv initscript instead?
22:47
(generated from init-ltsp.d too)
22:47
<vagrantc>
no idea
22:48
<alkisg>
So that they work on debian too instead of just ubuntu, I think sysvinit scripts can be launched on runlevels 6 etc?
22:49
<stgraber>
alkisg: you won't have a way to get them to work as quickly as the upstart jobs on Ubuntu though, so ideally keep the upstart jobs for Ubuntu and add sysvinit scripts for distros who need it (or let them add it ;))
22:49
<alkisg>
(the problem is that nbd-client root connections aren't closed, so nbd-server stays running on the server)
22:50
OK, will try to find the best way there

22:53
<vagrantc>
alkisg: it eventually times out, though, right?
22:54
<alkisg>
vagrantc: I'm not sure that keepalive is set, that would make it timeout after 2h 11m
22:54
I think it'd be much better to issue swapoff, nbd-client -d for swap and root, and then poweroff
22:54
<vagrantc>
sure.
22:55
instant poweroff always seemed like a silly feature to me...
22:55
instant boot is one thing, but instant poweroff, really?
22:55
<alkisg>
Well if nbd-client -d root-device is issued, initscripts will have nbd read errors
22:56
So after that last nbd-client -d, the only thing we can do is issue: echo o > sysrq
22:56
<vagrantc>
or you could not disconnect the nbd root process...
22:56
<alkisg>
...which would leave the nbd-server process on the server for I don't know how long, maybe even until server reboot

Hmm I do that frequently in the epoptes branch, and I never had to do that... sorry

<vagrantc>
it breaks the whole premise of revision control

Usually I test a lot before each commit, but we have a strict time schedule now, so I had to do it about 5 times in the last 3 days
23:01
<vagrantc>
ok, enough grumbling :)

rather than chmod'ing after creating files, we should be setting the umask
23:06
<alkisg>
Right. Also, when we deprecate port-based nbd exports, we should rename nbdswapd to mknbdswap like altlinux has it
23:07
It won't be a daemon anymore
23:08
For ltsp 6, I'd really like it if we broke a bit the backwards compatibility and cleaned up a lot of things
23:12
Ah, vagrantc, the nbd swap files have to have static names. I put them to /tmp/nbd-swap/<ip> because nbdswapd doesn't run as root and doesn't have access to /var/run or to /run, if you have any better ideas...
23:13
We don't have a service which could create /var/run/ltsp/swap + chown it on boot, do we?
23:15
Ideally, we should convince wouter to ship a swap export with nbd-server

We're down to 2 scripts only in the initramfs, init-premount/udhcp and init-bottom/ltsp. Next goal for ltsp 6, remove udhcp and use dhclient to renew the pxe ip from the real file-system :)
23:44
Maybe we could also do the cow mounting from the real file system and have nothing in the initramfs!
