Kalimera, Alkis!
00:51
<alkisg>
 hyvää huomenta, FrozenZia :)
00:51
<FrozenZia>
when you feel up to helping me out with my problem, now I'm *really
00:52
<alkisg>
If you're at work and able to try stuff, sure...
00:52
<FrozenZia>
* at home, and can't really do anything, but I did go back and do that one command, so I know the result.
00:52
<alkisg>
What did it say?
00:52
<FrozenZia>
http://paste.ubuntu.com/318214/
00:53
<alkisg>
Looks ok
00:53
If you wrote "exit" after that, it should have booted... unless some other problem was preventing it to boot
00:54
<FrozenZia>
Right. Well, no. I didn't understand what I was supposed to do at that point - just reported back.
00:54
Figured there would be a next step and NEXT step and a *NEXT* step....
00:55
<alkisg>
OK, let's do this on Monday then, when you'll be at work
00:56
<FrozenZia>
Agreed. A friend and I are going to have a sauna nearby where I work, so I may pop in and try just exiting from Busybox, but if there's more trouble-shooting to do, I'll save it for Monday.
00:57
<alkisg>
Do remember to give the nbd-client command before exiting
00:57
(unless you left it open, that is...)
00:59
<FrozenZia>
ok - I think I left it open, but it was late....

<ftherese>
is it possible to do fsck commands on a thin client?
04:47
since the stuff is mounted via fuse
04:48
and the thin client doesn't contain the fsck commands or a root user

The thin client DOES contain the root user

and the fsck command is there
07:39
but running fsck on an ltspfs mount won't work.

Was wondering if someone could help me with ltsp-localapps. I followed instructions from URL: https://wiki.edubuntu.org/LTSPLocalAppsJaunty , and didn't know last step "Change your /etc/ltsp/dhcpd.conf to have your client using the new chroot with localapps". Regardless, Installed ubuntu alternade (mode "normal") on workstation and installed game "frozen-bubble". When I boot workstation from LTSP network, open a shel
11:09
l and run command: ltsp-localapps frozen-bubble it just goes to the next shell prompt... Was wondering if I am missing any important steps. I definately want to use ltsp-localapps for the lab I'm setting up...

<homer01>
hi
11:51
i've a problem
11:51
i've install my ltsp environment
11:51
my thin client boot
11:51
get the IP address from dhcp server
11:51
download the image
11:52
and ...... stay here
11:53
does somebody have an idea??
11:55
<alkisg>
What do you mean "download the image"? The kernel? What's the last message you see? And, distro/version?
11:56
<homer01>
i use ubuntu server 9.10 amd64 for the server
11:57
and i've build an image with ubuntu desktop 9.10 i386
11:57
yes download the kernel and i've no message
11:57
<alkisg>
Can you upload your /etc/ltsp/dhcpd.conf to http://pastebot.ltsp.org ?
11:58
<homer01>
yes just a minute
11:59tstafford has quit IRC
12:01tstafford has joined #ltsp
12:02
<homer01>
i can't connect to the pastebot.ltsp.org page
12:02
<alkisg>
Try paste.ubuntu.com instead
12:04
<homer01>
http://paste.ubuntu.com/318796/
12:07
<alkisg>
"/var/lib/tftpboot/ltsp/i386/pxelinux.0" ??
12:07
That should be relative to /var/lib/tftpboot/ ...
12:07
Did you change your tftp server to serve the whole / ?
12:07
That would be insecure...
12:07
<homer01>
??
12:08
<alkisg>
What does this give you? grep tftp /etc/inetd.conf
12:10
<homer01>
tftp dgram udp wait root /usr/sbin/tcpd /usr/sbin/in.tftpd /var/lib/tftpboot/ltsp
12:11
<alkisg>
Urm, yeah, those aren't the default values
12:12
Neither in dhcpd.conf, nor in inetd.conf
12:12
I wonder why it boots at all... it shouldn't even be finding pxelinux.0..
12:12
<homer01>
yes i've try a lot of thing
12:13
because this morning the thin client give me an error 1
12:13
file not found
12:13
when it wants to download the kernel
12:13
so i've look at my old machine to copy the differents config files
12:14
<alkisg>
Ouch. How old? What distro/version did it have?
12:14
<homer01>
ubuntu 8.04
12:15
<alkisg>
And you had that dhcpd.conf in 8.04?
12:15
<homer01>
yes sir
12:15
<alkisg>
It shouldn't be booting with that dhcpd.conf... :-/
12:15
<homer01>
and it work very well
12:15
i've just change the ip address of the network
12:16
actually 192.168.100.* 192.168.1.* for the old one
12:16
<alkisg>
Do you have access to the 8.04 file system?
12:16
<homer01>
yes
12:16
<alkisg>
I wonder what did it have in inetd.conf
12:16
<homer01>
i'm on the machine with the 8.04
12:16
<alkisg>
grep tftp /etc/inetd.conf
12:16
Ah, so it had that line that you pasted?
12:17
<homer01>
tftp dgram udp wait root /usr/sbin/tcpd /usr/sbin/in.tftpd /var/lib/tftpboot/ltsp
12:17
last time i give you the message for the new machine
12:17
<alkisg>
Well, with those settings, the clients would be trying to fetch this file: /var/lib/tftpboot/ltsp/var/lib/tftpboot/ltsp/i386/pxelinux.0
12:17
<homer01>
it won't work for sure
12:18
<alkisg>
That's why I'm wondering how it ever booted!
12:18
<homer01>
i understand
12:18
<alkisg>
The tftp root is: /var/lib/tftpboot
12:18
(without the ltsp)
12:18
<homer01>
but i've actually my daughter who is connected
12:18
<alkisg>
The filename is: /ltsp/i386/pxelinux.0
12:18
(without the /var/lib/tftpboot)
12:19
Why don't you restore the old configuration in 9.10, and we'll take it from there?
12:19
<homer01>
well how can i do that?
12:19
'm not sure i've made a copy of all the files
12:20
i've modified
12:20
<alkisg>
Can you reinstall ltsp-server-standalone? Without removing the chroot, that is..
12:20
<homer01>
i've the original dhcpd.conf
12:20
<alkisg>
Purge the whole things along with all the dependencies (tftp, dhcp3-server etc) and then reinstall it?
12:21
something like this: sudo apt-get --auto-remove purge ltsp-server-standalone
12:21
sudo apt-get install ltsp-server-standalone
12:21
<homer01>
ok i'll do that
12:24
ok i've remove everything
12:25
<alkisg>
So is /etc/ltsp/dhcpd.conf deleted?
12:25
<homer01>
and i'm reinstalling everything...
12:25
<alkisg>
...and you don't have a tftp line in /etc/inetd.conf ?
12:25
<homer01>
just need to wait a couple of minute
12:27Egyptian[Home] has quit IRC
12:28Egyptian[Home] has joined #ltsp
12:37
<homer01>
i've a new clean dhcpd.conf and a commented line about tftp in inetd.conf
12:38
<alkisg>
Commented? it shouldn't be commented
12:38
tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot
12:39
<homer01>
that's it with a # in front of the line
12:39
so i remove it?
12:39
<alkisg>
Ugh, too much unknown configuration there :)
12:40
What do you get with this? cat /etc/default/tftpd-hpa
12:41
<homer01>
#Defaults for tftpd-hpa
12:41
RUN_DAEMON="no"
12:41
OPTIONS="-l -s /var/lib/tftpboot"
12:43
<alkisg>
OK... well, yes, remove the comment from inetd.conf
12:43
What do you have in /etc/network/interfaces ?
12:44
<homer01>
i've done it
12:44
auto eth0
12:44
iface eth0 inet static
12:45
address 192.168.100.1
12:45
netmask 255.255.255.0
12:45
network 192.168.100.0
12:45
broadcast 192.168.100.255
12:45
<alkisg>
eth0 is the LTSP-facing NIC?
12:45
<homer01>
dns-search springfield.lan
12:46
yeap
12:46
<alkisg>
OK, then change 192.168.0.xxx in /etc/ltsp/dhcpd.conf to 192.168.100.xxxx
12:46
<homer01>
i've remove the loopback interface and the commented line
12:46
<alkisg>
Then, run: sudo invoke-rc.d dhcp3-server restart
12:46
and finally: sudo invoke-rc.d openbsd-inetd restart
12:47
That should get you to a default ubuntu installation, so we can see the problem from there.
12:48
<homer01>
ok i've done it
12:49
<alkisg>
Boot a client, where does it hang now?
12:50
<homer01>
same thing i download the kernel
12:51
i've done writing on the screen
12:51
and that's it
12:52tstafford has quit IRC
12:52
<alkisg>
So it properly first loads pxelinux, and then vmlinuz ?
12:53

alkisg you're always here?
13:08* alkisg has to help some person here locally, will be back in a while...
13:08
<sbalneav>
Afternoon all
13:12
<alkisg>
homer01: what's the last message you see on screen?
13:12
Hi sbalneav
13:12
<homer01>
the question about pxelinux What do you have there? (use paste.ubuntu.com): ls -lha /var/lib/tftpboot/ltsp/i386
13:13
<alkisg>
homer01: no, on the client screen, when it tries to boot
13:13
<homer01>
and i've answer with this : http://paste.ubuntu.com/318831/
13:13
<alkisg>
No no I mean when you try to boot the client
13:13
<homer01>
get the adresse from
13:13
the dhcp client
13:14
get pxelinux i think
13:14
a series of point which finished with 'Done'
13:14
dhcp server*
13:14
<alkisg>
This is just after pxelinux: http://www.yourwarrantyisvoid.com/wp-content/uploads/2009/08/pxelinux-boot.bmp
13:15
If you see all these "trying to load", then it correctly loads pxelinux. Does it?
13:17
<homer01>
i don't see this
13:18um|U is now known as wthww

13:18wthww is now known as ulterior_modem
13:18
<homer01>
and when it's finished loading i've the ' Done' text
13:19
on the old system after that i get the ubuntu splash screen
13:21
no the text is Loading 192.168.100.1:/ltsp/i386/nbi.img
13:21
...(ELF)
13:21
.............................Done
13:24
<alkisg>
Ah, ok
13:24
The problem is with the karmic .nbi image, I've heard of others having that problem
13:25
How do you boot the client? With a floppy or cd?
13:25
Or is it an old thin client (etherboot)?
13:26
<homer01>
i've create an image on rom-o-matic that i've put on the hard drive
13:27
<alkisg>
Then create a new one, with gpxe
13:27
!gpxe
13:27
<ltspbot>
alkisg: "gpxe" is the successor to etherboot. You can find it at: http://etherboot.org/wiki/index.php
13:27
<alkisg>
http://rom-o-matic.net/gpxe/gpxe-0.9.9/contrib/rom-o-matic/
13:28
This uses pxelinux instead of nbi.img, and it's much better. And it works in Karmic.
13:30
!forget gpxe
13:30
<ltspbot>
alkisg: The operation succeeded.
13:31
<alkisg>
!learn gpxe as the successor to etherboot (http://etherboot.org). To download bootable floppy, cd, usb, kernel etc images, visit http://rom-o-matic.net/

13:34
<homer01>
ok i'll try that
13:34
<msaul_>
Was wondering if someone could help me out with ltsp-localapps (I'm close to having LTSP lab installed)... It just doesn't work correctly...
13:34
the ltsp-localapps part that is...
13:34
<homer01>
i'll download an image put it on the hard drive
13:35
and i'll be back in 1 hour
13:37
<msaul_>
When I issue command like ltsp-localapps frozen-bubble from shell, does nothing (just goes not next prompt)...
13:38
I followed instructions via URL: http://ubuntuforums.org/showthread.php?t=1040198 , but suspect I missed something?
13:44
<alkisg>
msaul_: did you install frozen-bubble in the chroot?
13:46
<msaul_>
Not sure.... I did issue the commands: sudo chroot /opt/ltsp/i386;sudo apt-get update;sudo apt-get install frozen-bubble
13:46
then I did an image update
13:46
I installed Ebuntu 9.10 alternate CD (normal mode) to the thin client and installed the game frozen bubble.
13:47
<alkisg>
msaul_: well, if you do: ltsp-localapps xterm, does an xterm pop up?
13:47
"I installed Ebuntu 9.10 alternate CD (normal mode) to the thin client" ==> wait, what?
13:48
You don't install stuff to the thin clients... you only install stuff on the server
13:48
<msaul_>
OK, I did that then, no problem
13:49
<alkisg>
?
13:49
<msaul_>
The thin client has a 80 GB hard drive, and thought I had to do that...
13:49
<alkisg>
Urm, no, if you install an OS locally it isn't a thin client anymore
13:49
<msaul_>
Right now, thin client is booted from LTSP to it is acting like one...
13:49
<alkisg>
Of course you *can* do that; it's like having a dual-boot pc
13:50
<msaul_>
I'm just interested in keeping it simple, so your suggestion is better.
13:50
I assume that do damage was done, since it is acting like a thin client right now anyways....
13:50
I did set LOCAL_APPS_MENU=True in lts.conf
13:51
I did run ltsp-update-image for that setting to take effect....
13:51
There is one thing that I saw on another blog, that I didn't do...
13:51
<alkisg>
OK, what do you get with ltsp-localapps xterm ?
13:52
<msaul_>
It worked...
13:52
It brought up xterm window....
13:53
<alkisg>
OK, in *that* xterm, run frozen-bubble
13:53
(with no ltsp-localapps in front)
13:53
<msaul_>
says command not found (by name only, I will try full pathname)...
13:54
<alkisg>
/usr/games/frozen-bubble
13:54
<msaul_>
Doesn't have PATH for frozen-bubble in xterm
13:54
bash: /usr/games/frozen-bubble: No such file or directory
13:54
<alkisg>
dpkg -l frozen-bubble
13:55
<msaul_>
In the xterm window?
13:55
<alkisg>
Yes
13:55
<msaul_>
No packages found matching frozen-bubble.
13:55* alkisg guesses you didn't install frozen-bubble in the chroot after all... or you didn't update the image. In any case it isn't there. :)
13:56
<msaul_>
do you suggest that I do the installing via the xterm window for all situations of ltsp-localapps?
13:57
<alkisg>
No
13:57
We didn't install anything in the xterm, we just verified that you didn't install it at all
13:57
Any installations should happen in the chroot
13:57
Close the local xterm
13:57
And run those:
13:58
sudo chroot /opt/ltsp/i386
13:58
apt-get install frozen-bubble
13:58
What do you get with this?
13:58
<msaul_>
frozen-bubble is already the newest version.
13:59
While being unpriviledged user: which frozen-bubble /usr/games/frozen-bubble
14:00
<alkisg>
You don't need frozen-bubble on the server, only on the chroot
14:00
Type `exit` to exit the chroot
14:00
Run: ls /opt/ltsp/i386/usr/games/frozen-bubble
14:00
is it there?
14:01
<msaul_>
Just give me a second, want to try this again to be sure...
14:02
Yes, /opt/ltsp/i386/usr/games/frozen-bubble is there... (I exited chroot) before issuing command...
14:03
Do you want me to update ltsp image again just to be sure?
14:04
<alkisg>
Yup
14:05
<msaul_>
When it is finished, do I need to restart client?
14:05
btw, would it matter that I'm doing these commands via chroot while I am logged onto a thin client?
14:07
<alkisg>
"via chroot" ?
14:07
Yes, you need to restart the client
14:07
And no, it doesn't matter if you run sudo ltsp-update-image from a thin client...
14:08
<msaul_>
OK, since I'm chatting via thin client, I will exit, reboot just thin client and reconnect...
14:08msaul_ has quit IRC

14:12
<msaul_>
OK. Rebooted, and ran /usr/games/frozen-bubble in xterm window and worked. Worked well as if being run by thin client itself....
14:13
I didn't get sound, but still checking...
14:14
Weird, two volume applets appear in the upper panel now...
14:16
I removed volume applet, I'm going to reboot thin client again...

hi, dunno if somebody tried ltsp on voyage 0.6 yet but i got a strange rpc failed: 2 on the client while trying to mount root via nfs
16:02
<vagrantc>
voyage is a distro?
16:03
<magni>
