14:22* computer_freak_8 testing
14:22
<computer_freak_8>
okay, I remember how to do IRC now. :)
14:23
I'm having some issues with an LTSP server I setup - it's probably user/admin (my) error, but it's frustrating nonetheless.
14:24
<highvoltage>
hey computer_freak_8. fire away with your questions I'm sure someone will be willing to help
14:24
<computer_freak_8>
It can boot, and show the login screen, but fails after username/password are entered; in the logs, I see "nbd9:" complaining.
14:24
"unknown partition table", followed by
14:24
"NBD_DISCONNECT"
14:24
followed by
14:25
"Receive control failed (result -32)"
14:25
and finally "queue cleared"
14:25
thanks, I'm a slow typist. :)
14:25
I found this: http://ubuntuforums.org/showthread.php?p=8517198#post8517198
14:26
but it didn't seem to help much yet.
14:26
<highvoltage>
do you get a login screen again?
14:26
<computer_freak_8>
yes, I do
14:27
<highvoltage>
it's possible that those nbd errors are unrelated, it seems that you do at least haver your root filesystem mounted (since you can boot your thin client)
14:27
have you tried running the following on the server?
14:27
sudo ltsp-update-sshkeys
14:27
<computer_freak_8>
true, as well as SSH working.
14:27
<highvoltage>
sudo ltsp-update-image
14:28
<computer_freak_8>
running that again now...
14:28
<highvoltage>
that's usually something people leave out when installing ltsp on ubuntu
14:28
you should restart the thin client after doing that
14:28
<computer_freak_8>
I'm actually on Debian, but they're similar enough, I can usually translate back-and-forth
14:29
<alkisg>
dgroos: pong?
14:29
<highvoltage>
ah, did you manually configure nbd? debian uses nfs by default
14:30
<computer_freak_8>
Oh, good question. Not that I'm aware of, but I couldn't even get to the login screen before I disabled the kernel NFS parameters.
14:30* alkisg thinks that running ltsp-update-image on debian automatically switches it to nbd
14:30
<computer_freak_8>
default ltsp
14:30
label ltsp
14:30
kernel ltsp/i386/vmlinuz
14:30
append ro initrd=ltsp/i386/initrd.img nbdport=2001
14:31
that's my pxelinux.cfg/default file
14:31
(the one that gets me to the login screen)
14:31
alkisg: possibly, but is that good or bad?
14:32
<highvoltage>
that looks good
14:32
<alkisg>
I haven't seen the whole conversation, I just saw the "I don't know how I switched to nbd" part
14:32
<computer_freak_8>
Oh, okay. LOL.
14:32
<alkisg>
If you're asking in general about nbd vs nfs, there are pros and cons to both cases
14:32
<computer_freak_8>
Is one better than the other for limited-RAM clients?
14:33
<highvoltage>
alkisg: he can't log in at ldm and sees a bunch of nbd errors while it restarts
14:33
(super-short and simple summary)
14:33
<computer_freak_8>
but I can login via SSH... which really confuses me.
14:35ddave7 has joined IRC (ddave7!~Miranda@109-183-95-158.tmcz.cz)
14:35
<highvoltage>
do you have to type 'yes' when logging in via ssh?
14:36
<computer_freak_8>
I did the first time.. but I'd never logged in from my workstation to that IP before, so I figured it was normal.
14:36markit has joined IRC (markit!~marco@88-149-177-66.staticnet.ngi.it)
14:37* alkisg commends on part of the discussion as he reads them...
14:38
<alkisg>
(05:24:29 μμ) computer_freak_8: It can boot, and show the login screen, but fails after username/password are entered; in the logs, I see "nbd9:" complaining. ==> that's normal, it's a test to see if there's a newer nbd image
14:38
It's normal that nbd9 gets disconnected
14:38
<computer_freak_8>
Oh, okay.
14:39
<alkisg>
!SCREEN_08
14:39
<ltsp>
alkisg: 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..
14:39
<alkisg>
computer_freak_8: from SCREEN_08, run: ssh user@server
14:39
Replace "user" with an existing username, but leave "server" as it is, don't change it with anything
14:39
See if you get any warnings at all, e.g. "adding ssh keys for pc xxx"
14:40
<computer_freak_8>
by "from SCREEN_08", you mean, from my SSH shell?
14:40
<alkisg>
You have ssh to the client?
14:40ddave71861 has joined IRC (ddave71861!~Miranda@193-4.gprs.tmcz.cz)
14:40
<alkisg>
Lets start over
14:40
To troubleshoot the problem, you'll need a root shell on your thin client
14:40
The screen_08 above is a method to get such a shell
14:40
<computer_freak_8>
okay, got it. wasn't thinking there..
14:40
<alkisg>
ok

14:44
<computer_freak_8>
shoot. Apparently VirtualBox doesn't allow [Ctrl]+[Alt]+[F-key]
14:45
gotta grab a physical thin client, one moment...

14:49
<alkisg>
computer_freak_8: right ctrl+fx
14:49
(in vbox)
14:53
<markit>
btw, don't know if related, but with Kubuntu after login crashes if you have effects enabled
14:53
computer_freak_8: are you using kde by chance?
14:53* markit knows that he is almost alone on this planet to use KDE with ltsp
14:54
<computer_freak_8>
Not that I'm aware of. I think it's either Gnome or LDM.
14:55
it has the "LTSP.org" login splash-screen
14:55
if that helps.
14:57
for the SCREEN_0n variables, what syntax should I be using from my shell prompt? Is "set -e SCREEN_08=shell" sufficient for 08?
14:57
oh, wait, that was another post..
14:58
ssh user@server, replacing "user"...
14:59
I tried, from the thin client's shell, "ssh root@server"
14:59ddave71861 has left IRC (ddave71861!~Miranda@33-4.gprs.tmcz.cz, Ping timeout: 258 seconds)
14:59
<computer_freak_8>
it said root@server's password:
14:59dlezcano has left IRC (dlezcano!~dlezcano@nat/ibm/x-uxmjvvssridpsowv, Ping timeout: 260 seconds)
15:00
<computer_freak_8>
so I gave it, but it said "permission denied, please try again:"
15:00
all three times
15:01
<alkisg>
The default ssh settings dissallow root from logging in
15:01
Try with a user
15:01
<computer_freak_8>
ah, okay.
15:02
is it okay if the user is a "sudo-er"?
15:02
<alkisg>
sure
15:02
bbiab
15:03Gremble has left IRC (Gremble!~Ben@cpc12-aztw24-2-0-cust146.aztw.cable.virginmedia.com, Quit: I Leave)
15:03
<computer_freak_8>
okay, that worked - a couple of notes, though:
15:04
1. I couldn't login to tty3 as myself; I had to login as root
15:04
2. when ssh-ing to "server" as myself, it corrects the hostname after I login.
15:05
<alkisg>
Did you get any warnings about "adding ssh key for pc xxx"?
15:05
<computer_freak_8>
nope
15:05
<alkisg>
OK, now logoff from ssh, press alt+ctrl+f7 to switch to ldm, and try logging in with the same user/password that you used before
15:06
<computer_freak_8>
so logout of ssh, but stay logged into the root prompt?
15:06
<alkisg>
Yes
15:06
<computer_freak_8>
okay, one moment
15:07
It didn't work.
15:07
<alkisg>
(don't pay too much attention to this as is doesn't matter: about (06:04:25 μμ) computer_freak_8: 1. I couldn't login to tty3 as myself; I had to login as root
15:07
you should have tried tty2, where you'd get a shell without logging in)
15:07
<computer_freak_8>
It appeared to do the same thing as before - just re-start the login screen
15:07
<alkisg>
OK, now let's see the logs
15:07
On your server, check /var/log/auth.log
15:07
Do you see both of the connection attempts there?
15:08
<computer_freak_8>
under the chroot, or the main part?
15:08
<alkisg>
The one from tty3, and the one from ldm?
15:08
The main part
15:08

15:08
<alkisg>
OK, so you did login, and probably something crashed X, and you logged out
15:09
Now, put /home/jared/.xsession-errors to pastebin
15:09
!pastebin

alkisg: pastebin: the LTSP pastebin is at http://ltsp.pastebin.com. Please paste all text longer than a line or two to the pastebin, as it helps to reduce traffic in the channel. Don't forget to paste the URL of the text here..
15:09
<computer_freak_8>
quick question: what are all those things being posted from the "ltsp" username?
15:10
<alkisg>
The ltsp username is a bot, a program that helps in the channel
15:10
<computer_freak_8>
oh, okay.
15:10
that makes sense, then.
15:10
<alkisg>
It remembers things and we ask it to tell them with the ! in front
15:11
<computer_freak_8>
oh, nice!
15:11
that might be my next project... an irc server with a memory bot!

15:12* computer_freak_8 rolls eyes
15:13
<computer_freak_8>
okay, so, an interesting issue:
15:13
my chroot does not have a /home/jared folder, and thus no .xsession-errors file.
15:13
<alkisg>
Not in the chroot
15:13
In the server
15:13
<computer_freak_8>
My server has a /home/jared folder, but not .xsession-errors
15:14
<alkisg>
It's hidden
15:14
How did you try to see that file? With some file manager?
15:14
Try with a command: tail /home/jared/.xsession-errors
15:14
<computer_freak_8>
http://pastebin.com/8z9vLnks
15:14
does not exist
15:14
<alkisg>
Indeed
15:15
Do you have a desktop environment on the server?
15:15
E.g. gnome, kde etc?
15:15
<computer_freak_8>
um... good question.

<alkisg>
Which debian version is that?
15:17
Try this, on the server, the main part: dpkg -l gnome-terminal
15:17
<computer_freak_8>
none found.
15:17
I'm installing "desktop-base" now.
15:18
this was a real ID 10-T error, I think.
15:18
it would definitely explain why I can't get a desktop session...
15:18
<alkisg>
Yup :)
15:18
Hehe first time I saw ID 10-T :D
15:19
<computer_freak_8>
I've been using it for a while - I pull them often. :)
15:19
I don't know who came up with that term, though.
15:20
So, I'm a bit confused with the chroot/not-chroot thing: when does it move to the chroot?
15:21
<alkisg>
An easy way to think about it is this:
15:21
The chroot is a very small OS that is used to boot the client
15:21
Then the client does a "remote desktop" to the server
15:22
And every program the user runs, it runs on the server
15:22
<computer_freak_8>
oh, okay... my thinking was backwards.
15:22
<alkisg>
So, where would openoffice, firefox, gnome etc be? In the server or in the chroot?
15:22
<computer_freak_8>
server
15:22
<alkisg>
Yup. Where would the user accounts be?
15:22
<computer_freak_8>
unless you're me, and misconfigure it.
15:22
server
15:22
except root
15:22
<alkisg>
Yup, you got it
15:22
<computer_freak_8>
it'll be both places
15:22
<alkisg>
Not really
15:22
There's an ltsp-build-client switch for that
15:22
--root-pass, I think
15:23
<computer_freak_8>
oh, okay.
15:23
<alkisg>
If you set that, you enable the root account on the client
15:23
I believe you did that, otherwise you'd be unable to log in as root on the thin client
15:23
<computer_freak_8>
I just did a ltsp-update-image, and it only showed one user/uid this time (root), instead of the three it was previously showing.
15:24
okay, so, I'm back to where I started, working-wise, unless my server just needs rebooted.
15:24
So I'm trying that now.

what is LTSP_CONFIG=True?

SCREEN_DEFAULT does exist, just found it in the source.

And apparently LTSP_CONFIG=True makes your lts.conf being ignored.

LTSP_CONFIG=True isn't harmful, unless you want to explicitly set LTSP_CONFIG=False
19:33

hmm, airfare to Portland, OR is not too much more than airfare to Portland, ME.
19:33
<vagrantc>
in which case, you'd change the False to true.
19:34
or vice-versa.
19:34
i think i had debian add LTSP_CONFIG=True by default before the bugs were fixed with empty lts.conf
19:34

I'm actually using Debian, so that might have something to do with it.

whatever you do, don't run ltsp-update-image. it's evil on debian.
19:35
<Hyperbyte>
vagrantc, you sure? I just saw in the source that 'LTSP_CONFIG' is set to True once lts.conf is loaded, so it doesn't get loaded twice. Unless I read wrong, that would seem to imply lts.conf won't get loaded?

ltsp-update-image is evil; that's why I made a backup of my pxelinux.cfg/default file.
19:38

vagrantc, my apologies. That's from the LTSP source though. # Don't source this file if it has been sourced already

19:40

Eh, I've got a root password, so I can login.
19:40
<vagrantc>
computer_freak_8: what are you trying to do again?
19:40
<computer_freak_8>
Get my LTSP setup to auto-login.
19:40
I can do it manually, but I'd like it to auto-login with the user: guest and password: pass
19:41
(I might change those later, for security, but for now, those are what I'm working with)
19:41
<vagrantc>
computer_freak_8: you need one user per thin client
19:41
<computer_freak_8>
Oh...
19:41
I can't have one user, multiple thin clients?
19:41
<vagrantc>
not if you want to use the thin clients at the same time :)
19:42
one user, one login. it's due to bugs in many stupidly written programs
19:42
<computer_freak_8>
Oh, okay. :)
19:42
<vagrantc>
you should be able to do it, but silly things like mozilla prodocuts, openoffice/libreoffice, gnome, etc. all make bad assumptions.
19:43
<computer_freak_8>
So, what would I need to do to get it setup properly? Add per-MAC-address configuration of some sort?
19:44
<vagrantc>
if you want, or you can configure the autogenerated username/passwords
19:45
defaults to ltsp(some number based on ip address)
19:45
i.e. for a network with 192.168.0.100 ... 192.168.0.250 , it will use ltsp100 ... ltsp250
19:45
password defaults to the same as username
19:46
or you can just set a global password for all the users
19:46
or use ssh keys ... but that's a bit more involved (though my preferred method)
19:46
<computer_freak_8>
oh, okay....
19:47
Does it matter that my DHCP server is not the same server as my LTSP server?
19:47
<vagrantc>
i prefer to set it to use ssh keys and set up passwordlless accounts, otherwise they can change the password and such
19:47
<computer_freak_8>
And how does that work with diskless clients?
19:47
<vagrantc>
computer_freak_8: shouldn't be a problem.
19:47
<computer_freak_8>
okay
19:47
<vagrantc>
computer_freak_8: so, you can log in manually, but autologin isn't working?
19:47
<computer_freak_8>
correct
19:48
<vagrantc>
and if you put LDM_USERNAME=guest and LDM_PASWORD=pass, and LDM_AUTOLOGIN=true, it doesn't work?
19:48
<computer_freak_8>
Correct.
19:49
Then again, might it be the rest of my lts.conf file?
19:49
http://pastebin.com/yJ3guGkN
19:49
<vagrantc>
you might try LDM_GUESTLOGIN=true instead of LDM_AUTOLOGIN... and then set SCREEN_07=ldm, SCREEN_08=shell, SCREEN_DEFAULT=07
19:49
<computer_freak_8>
Okay, does it matter if it's "True" or "true"?
19:50
<vagrantc>
looks fine.
19:50
true/True/tRUe are all the same :)
19:50
<computer_freak_8>
Good. I was hoping there wasn't more stupidly written code there. :P
19:50
<vagrantc>
though the officially supported are true/True/y/Y, if i remember correctly.

actually the ThinClient device is trying to connect to it. But getting 400

bakytn, do you have ltsp-cluster-accountmanager running on your appserver ?
20:14
<bakytn>
mgariepy, yes
20:16
mgariepy, hereis the contents of /etc/ltsp/accountmanager.conf http://pastebin.com/5nXMdZWZ
20:16
<mgariepy>
netstat -puant|grep 8001
20:16

20:16
<bakytn>
tcp 0 0 0.0.0.0:8001 0.0.0.0:* LISTEN -
20:16

you should run this as root

telnet localhost 8001
20:19
then type getkey
20:20
<bakytn>
returned ssh-rsa and then "closed by foreign host."
20:21
not sure which of the pubkey it returned because the app server pubkey is different
20:21
(ops sorry disregard the last message)
20:22
<mgariepy>
on 192.168.1.191
20:22
who is triing to ask getkey to it ?
20:22
the thin client ?
20:22
<bakytn>
yes. 192.168.1.191 is the ThinClient device IP (got from DHCP)
20:23
<mgariepy>
ok 192.168.1.191 is your loadblancer?
20:23
huh
20:23
<bakytn>
the loadbalancer is 192.168.1.239 (the root server)
20:24
192.168.1.191 is the Thin Client device IP
20:25
<mgariepy>
what configuration for LDM_SERVER do you have in ltsp-cluster-control ?
20:26
<bakytn>
sorry, where should I see it?
20:26
ah moment
20:26
it is: %LOADBALANCER%
20:26
LDM_SERVER is %LOADBALANCER%
20:27
<mgariepy>
ltsp-cluster-lbagent running on your appserv ?
20:27Gadi has joined IRC (Gadi!~romm@ool-18bbe47a.static.optonline.net)
20:28
<bakytn>
here is my lbsconfig.xml http://pastebin.com/xTDy023E
20:28
<mgariepy>
the problem is that your loadblancer server doesn't have any client in is pool. when the LDM_SERVER config on your thin client is empty it takes the ltsp-root server
20:28
<bakytn>
yes lbagent is running
20:28
<mgariepy>
on ltsp-root
20:28
ping vserver1-appserver
20:28
01
20:28
<bakytn>
it bings
20:28
pings
20:29
<mgariepy>
Cannot retrieve node 'vserver1-appserver01', error:<class 'socket.timeout'>
20:29
<bakytn>
yes. that's strange.
20:29
it's in both /etc/hosts
20:29
IP's are valid (double checked)
20:30
so they both can see each other by hostname's
20:30
may be the problem is that so the Thin Client can't resolve the hostname to ip?
20:30
I mean the Thin Client device
20:30
<mgariepy>
can you put the ip in lbsconfig.xml in the address field.
20:30
no
20:31
<bakytn>
ok moment
20:31
<mgariepy>
the thin client doesn't talk to the loadbalancer, and it receive the ip address for the server it needs to connect to.
20:31
<bakytn>
ok
20:32
I changed the lbsconfig to use IP address. I need to /etc/init.d/ltsp-cluster-lbserver restart right?
20:32
<mgariepy>
is lbagent binded to the port 8000 on the appserv ?
20:32
yeah
20:32
<bakytn>
yes it's binded to 8000
20:32
<mgariepy>
ok
20:32
<bakytn>
let me restart thin client device then?
20:33
<mgariepy>
do you see the same error in the /var/log/ltsp-cluster-lbserver.log ?
20:34
<bakytn>
the last lines from /var/log/ltsp-cluster-lbserver.log http://pastebin.com/dChJA5gV
20:35
here http://pastebin.com/5nXMdZWZ what does key=PUT-A-KEY-HERE means?
20:36
<mgariepy>
wget -q -O - http://192.168.1.239:8008/
20:37
<bakytn>
the command you provided is returning: 192.168.1.241
20:37
192.168.1.241 is an IP of vserver1-appserver01
20:37
<mgariepy>
good.
20:38
does your thin client works now ?
20:38
<bakytn>
I restarted Thin Client. no result
20:38
<mgariepy>
can you run """getltscfg-cluster -a""" on the thin client
20:39
<bakytn>
I need to SCREEN_02=shell (one moment)

do you have /etc/ltsp/getltscfg-cluster.conf in you thin client chroot ?

you see your thin client ?

in cluster control center gui? no..I don't see!!
20:55

no

Oo no!

did you ran ltsp-update-image after adding /etc/ltsp/getltscfg-cluster.conf ?
20:57
<bakytn>
in /var/log/apache2/access.log there is no IP of the thin client either
20:58
no I didn't run
20:58
<mgariepy>
run it and reboot.

Why don't you put your applications in /usr/share/applications like all other applications?

Just create .desktop files for them
21:46
<shawnp0wers>
alkisg - that's never worked for me, is it possible to make a sub-menu doing it that way?
21:46
<alkisg>
Sure
21:46
That's how packages create menus
21:47
<shawnp0wers>
Do they create menus, or conform to the freedesktop already-existing-menu structure?
21:47
<alkisg>
They create menus
21:47
E.g. wine even creates arbitrary ones, defined from microsoft windows programs
21:48
Applications > Wine > Programs > Microsoft Office > etc
21:48
<shawnp0wers>
I'll go peek at some .desktop files and see if I can make something work
21:48
<alkisg>
There's also debian helper dh* scripts for that, if you're making a package
21:48
Otherwise sure it can also be done manually

To create new menus, you'll also need menu files, not just desktop files

perahps that's what I've done wrong before
21:49
are the menu files located elsewhere?
21:50
<alkisg>
Yup, somewhere nearby, don't remember the location offhand

perhaps /usr/share/menu but I'm not certain

Hi all. I have a problem with my LTSP installation. I am running 11.04 edubuntu with 2 NICS. I built the environment with sudo ltsp-build-client --fat-client --fat-client-desktop edubuntu-desktop --arch i386 --skipimage The clients boot up fine but there is no internet connectivity. I know it is a natting issue but I followed http://pastebin.com/i7L7Jyf7 and https://help.ubuntu.com/community/UbuntuLTSP/ThinClientHowtoNAT with no success. eth0 is my LTSP ne
22:44
t 192.168.0.0/24 and eth1 my LAN. Ant ideas?
22:57

I wonder does your LTSP server have access to the internet?

yes it does

nroussi, cna you set default gateway for eth1?
23:42
route add default gw <gw_ip> eth1
23:43
<markit>
btw, b) solved, is a bug of the script http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=635086
23:45
<bakytn>
markit, what does "can't open 2 sessions in the clients" means? you can't launch two thin clients?
23:45
<markit>
bakytn: in K menu, when I enter the "leave" menu, I have "switch user" option
23:46
since there are 2 children for each pc, would love to be able to switch user on the fly
23:46
btw, I had the LDM_LIMIT_ONE_SESSION=true, now I've set to false and restarted the client
23:47
do I have to reboot the server too? (the "M$ way" ;P))
23:51
<bakytn>
markit, I suppose "switch user" option is not applicable in LTSP environment
23:51
<nroussi>
baktyn, I added the route. I cant test it now but my issuing a route command gives me this http://pastebin.com/2iPEfmRf
23:52
<bakytn>
markit, when you change lts.conf you dn't have to reboot the server nor update the image
23:52
markit, you would probably have to reboot your thin client
23:54
nroussi, can you ping 192.168.2.100 ?
23:56
<nroussi>
bakytn, when I ssh into the server from the LAN and I go into the chroot environment I can ping anything. From the clients though I cannot
23:56
<markit>
bakytn: sure, client rebooted but the option seems ignored (or seem to work like "lock screen" instead)
23:58
<bakytn>
markit, I think, not sure, that it's impossible to just swithc the users keeping previous session active. You have to logout first and then log in as a different user
23:58
nroussi, can you run ifconfig -a in clients?
23:58
<markit>
bakytn: ok, I thought was technically difficoult in fact...
23:58
my last and biggest problem is now keyboard
23:58
wondering if is a fault in detecting it, or whatever
23:59
<bakytn>
markit, I never had problems with keyboards in 11.04. Do you have any keyboard related settings in lts.conf? if yes, can you comment them out and try again?
23:59
<nroussi>
bakytn: yes let me go on a client to give you the output
