<gbaman>
hey alkisg got a weird bug.. Have some users on my LTSP server, and if I ls /home/pupil there is lots of files and folders
10:54
if I type cd ~ on the logged in LTSP client, I just have /home/pupil/desktop ?
10:56
if I ssh into the server, from the client using the users credentials, all files are there fine
10:58
have just tried creating a new user, it is the same
11:04
the home folders get reset on every reboot
11:04
weirdly isnt all the users..

<gbaman>
Not sure why I didn't notice the bug before, a user did and found a solution for it, at least when using NFS
11:26
https://github.com/gbaman/RaspberryPi-LTSP/issues/12
11:26
but not helping with NBD

12:50
<gbaman>
alkisg: ?
12:55
After more checking, it seems to be all uses now when using NBD
12:56
Are users home folders also shared via NBD?
13:13
<alkisg>
gbaman: by default, SSHFS is used for home dirs both when using NBD or NFS for /.
13:13
An alternative is to use NFS for home dirs, but that's not the default
13:13
<gbaman>
any idea why SSHFS isnt working?
13:14
<alkisg>
If the folder /home/pupil is already there, LTSP thinks that the sysadmin mounted the home dir via other means, so it's not using SSHFS
13:14
Does the problem happen on the first login of that student, or only on second, third etc logins?
13:15
<gbaman>
all
13:15
I was just checking my newly installed machine, it is all logins
13:15
not sure how I hadnt noticed it
13:15
<alkisg>
I mean first login after client boot
13:15
For the same user
13:15
<gbaman>
first login
13:15
tried multiple users
13:15
including new users
13:16
will create another new one now on this newly installed machine
13:16
<alkisg>
!vnc
13:16
<ltsp>
I do not know about 'vnc', but I do know about these similar topics: 'x11vnc', 'kvm-vnc'
13:16
<alkisg>
!x11vnc
13:16
<ltsp>
x11vnc: One way to share a graphical screen with a remote person is: [local pc] port forward 5500, run: vncviewer -listen [remote pc] sudo apt-get install x11vnc; x11vnc -noshm -connect <technician-ip>
13:16
<alkisg>
Nah
13:17
!learn vnc-plinet as to share your screen with me: sudo apt-get install x11vnc; x11vnc -noshm -connect plinet.ioa.sch.gr
13:17
<ltsp>
The operation succeeded.
13:17
<alkisg>
If you want, do that ^ from a client...
13:18
<gbaman>
ok, 2 secs
13:19
rebuilding NBD image..
13:20
<alkisg>
You can do it (apt-get install) live, on the fly, as long as you have root access on the client and it has enough ram
13:22
<gbaman>
ok, booting now
13:22
which I didnt have enabled :)
13:23
root is now enabled
13:25
<alkisg>
!screen_08
13:25
<ltsp>
screen_08: To get a root shell on a Debian thin client, put SCREEN_07=ldm, SCREEN_08=shell and SCREEN_DEFAULT=07 to lts.conf.
13:26
<alkisg>
...no need to update nbd to get root...
13:26
<gbaman>
does that command need to be run as root btw?
13:27
just ran it as normal user and ended up with quite a few errors
13:27
<alkisg>
The x11vnc command? No, as a user.
13:27
x11vnc -noshm -connect plinet.ioa.sch.gr
13:28
<gbaman>
well hello
13:31
just to clarify, it is a Raspberry Pi. Also I have got a file in /home/test1 called test.txt on the server
13:38
<alkisg>
gbaman: your fuse module isn't working
13:38
<gbaman>
ok?
13:38
<alkisg>
It don't know why, but it doesn't look ltsp related
13:39
So ask in #raspbian or wherever else you want, about how to make fuse work
13:39
Also try booting with an older kernel
13:39
<gbaman>
ok, will do
13:40
how will I know if it is working?
13:40
<alkisg>
if `sshfs user@server: /tmp/somedir` works
13:41
<gbaman>
ok
13:41
booting a normal sd card
13:42
<alkisg>
Or try netbooting the 3.2 kernel you have there
13:44
<gbaman>
normal raspbian sshfs not found :)
13:44
installing
13:44
<alkisg>
No problem there, you can install it, or just try `su -; modprobe fuse`
13:45
<gbaman>
fuse is happy on normal raspbian..
13:46
<alkisg>
What kernel?
13:46
3.13?
13:46
I.e. is that the same kernel you had while trying with ltsp?
13:46
<gbaman>
3.10.32+
13:46
<alkisg>
(04:46:24 μμ) alkisg: I.e. is that the same kernel you had while trying with ltsp?
13:47
I don't remember the version, so just say yes/no...
13:47
<gbaman>
not sure
13:47
files in boot folder are 3.10.3
13:47
<alkisg>
So it's not the same kernel
13:47
<gbaman>
hmm
13:47
<alkisg>
OK just boot ltsp with the 3.2 kernel
13:47
To try with that one
13:49
<gbaman>
am assuming it isnt as simple as just copying over the kernel files
13:49
as LTSP needs its stuff in the initrd
13:49
<alkisg>
In the image I saw, you had 3.2 installed
13:49
So it does contain the ltsp initrd stuff
13:50
Vnc from the server to me:
13:50
!vnc-plinet
13:50
<ltsp>
vnc-plinet: to share your screen with me: sudo apt-get install x11vnc; x11vnc -noshm -connect plinet.ioa.sch.gr
13:50
<gbaman>
ohh, found them
13:50
will try it first
13:53
think me and vagrantc had issues with this kernel..
13:53
booting
13:54
works
13:58
so is just that version of the kernel..
13:59
<alkisg>
Yeah it looks like fuse needs to access some symbol which isn't there, it doesn't sound ltsp related at all
14:00
<gbaman>
ok, yea, cant use this old kernel.. Does not have some of the new graphics accelerated stuff

14:13work_alkisg has joined IRC (work_alkisg!~alkisg@plinet.ioa.sch.gr)
14:30
<gbaman>
work_alkisg: how does one get kernel and initrd with LTSP stuff inside? Is it possible without rebuilding?
14:30
<work_alkisg>
All chroot kernels get the initrd stuff automatically
14:31
So just install any kernel in the chroot
14:32
<gbaman>
apt-get install linux-image-rpi wont grab the actual kernel, will it?
14:32
(is a shortcut to most recent version)
14:32
<work_alkisg>
https://packages.debian.org/search?keywords=linux-image-rpi
14:33
I've never seen pi, I don't know its packages
14:33
And I don't see them in the archive
14:33
<gbaman>
it is in the raspbian repo
14:33
<work_alkisg>
OK, but I don't want to learn about pi either
14:33
:)
14:34
No time for that, too busy trying to fix 14.04 for Greek schools...
14:34
<gbaman>
:)
14:34
how do you install a new kernel normally then?
14:34
(new to all this)
14:35
as installing that didn't seem to modify anything in the opt/ltsp/armhf/boot folder
14:41
<work_alkisg>
You can ask non-ltsp questions in your distro channel...
14:41
You can ask them here too, but it's more likely to get answers there
14:42monkwitdafunk has joined IRC (monkwitdafunk!~AndChat49@24.114.23.3)
14:42
<gbaman>
I already have asked there :)
14:43
nothing yet
14:43
<work_alkisg>
You can also ask in mailing list, google etc etc
14:43
(in the distro mailing list, not in the ltsp one)
14:44
<gbaman>
i know all that needs done is to grab the most recent kernel files (the 3.2 ones I have are waaay out of date) and generate the ltsp initrd
14:44
is the only way to do this with ltsp-build-client ?
14:45
<work_alkisg>
No, you only need to install the kernel in the chroot
14:45
You don't need to update anything and you don't need to run anything ltsp-related
14:46
<gbaman>
on normal plain debian, how would you go about installing the kernel?
14:46
<work_alkisg>
You would ask in #debian, not in #ltsp :)
14:46
<gbaman>
am assuming it isnt a simple single command then :)
14:46
<work_alkisg>
It is
14:47
I'm just trying to do some real work, so I'd prefer it if people ping'ed me only for ltsp questions, not for generic debian questions
14:47
<gbaman>
ok
14:47
<work_alkisg>
I don't even use debian in my systems...
14:47
(at least, not yet)
14:47
<gbaman>
oh yea, vagrantc was the debian guy :)
14:48
<work_alkisg>
Still, it doesn't matter...
14:48
I'm also using `sed`, and I don't like it if people ping me about sed questions... :)
14:48
<gbaman>
ok, I will figure it out
14:48
<work_alkisg>
That's why it's better to ask in the appropriate channels, _not_ ping specific people unless there's a reason to, and just wait patiently...
14:48
Or, use google, mailing lists, forums etc

Raspbian guys werent any help, rebuilding the OS
15:11
<effenberg>
https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1308572
15:11
lol
15:30
<gbaman>
ok work_alkisg I found them and have most recent versions, when I boot them though, it boots normally, not with ltsp. my guess being the LTSP scripts arent in the initrd
15:31
<work_alkisg>
ls $CHROOT/etc/kernel/postinst.d/ltsp-update-kernels
15:31
LTSP has that hook that automatically puts its stuff into any initrd that you install
15:36
<gbaman>
ltsp-update-kernels didnt work, it didnt make any change, just seemed to copy it to tftpboot folder
15:36
oops, didnt see one below
15:37
*comment
15:37
pis dont generate their own initrd it seems... they just grab it.. Yay..
15:43
think I might have figured it out

ok work_alkisg, did it, built an initrd for most recent pi kernel, with ltsp stuff in it
16:26
only to discover it does not have aufs...
