Hello, I was wondering if anyone could point me to a tutorial for converting a fedora ltsp install to NBD? Also, what's the best way to lock all users of all thinclients to just firefox? Also do not want them to be able to change anything about... well... anything really.

ok... i have several labs in rural schools, no internet... did a fresh install of edubuntu 9.10 with ltsp, try booting the think clients and they give squashfs errors if i boot more than one at a time... i can log in as a user on one that successfully boots, but as soon as i login on a second tc, the first one locks up
06:48
i don't have internet at these schools, so i can't rebuild using ltsp-build-client
06:50
other clients don't even boot.. they manage to download the image vie PXE and then hang after "....done" i'm thinking that might be a PXE error, so i'll try with gPXE disks next time i go out
06:50
server works fine, and the lab was running 7.04 with few to no problems
06:54
<alkisg>
" i can log in as a user on one that successfully boots, but as soon as i login on a second tc, the first one locks up" ==> are you logging in with the same or with a different user?
06:55
<avolkovi>
different user
06:55
it's really bizarre... what blows my mind is i can't boot several tc's at once
06:56
if i go one at a time and i wait til each makes it to the login screen before proceeding i can atleast get them to login screens
06:56
but logging in on more than one is out of the question
06:58
i thought it might've been a hard drive problem on the server... like it was sending over a corrupt image, but problem persists after clean installs on two different hdd's
06:59* avolkovi needs to be afk for a bit while he teaches... pm if you have any ideas
07:00
<alkisg>
The squashfs errors in 9.10 isn't really unusual, but it works with them
07:00
The "cannot login more than one" seems like a dhcp issue
07:01
The "hangs if I logon to another pc" is really bizzarre :)
07:01
*cannot boot more than one
07:02* _UsUrPeR_ has gotten 4 personal messages since yesterday morning about "why they cannot talk in #LTSP

good morning
08:35
Is anyone aware what controls the available sessions you see with ldm?
08:36
<appiah>
controls how?
08:37
<grantk>
appiah: well, I am working on ldm load balancing and whenever I give the choice of more than the server that gave my client it's ip address I lose the option for a kde session. So I only have the default and Failsafe Xterm. This leads me in a loop where I can login to ldm, black screen, back to ldm.
08:37
<Gadi>
grantk: ldminfod
08:37
<grantk>
so I wanted to try and hunt down a reason why the info was not returned
08:37
<Gadi>
try installing the ldm-server package on the app servers
08:38
<grantk>
Gadi: I have that installed on both servers, Actually use it to choose the best server
08:38
Gadi: You mentioned the app server. I just have two servers installed with the ltsp packages, one is not really designated as an app server
08:39
<Gadi>
do they both have ldminfod?
08:39
<grantk>
Yes
08:39* Gadi believes ldminfod runs out of inetd
08:39
<Gadi>
so, check that inetd is running
08:39
<grantk>
ok
08:40
<sbalneav>
Morning all

re
08:42
<grantk>
Gadi: I am not sure how to check if inetd is running via the client, I can not login of course, But I did check out the inetd.conf in the chroot and saw the calls to ldminfod as well as the calls to nbdswapd, when I boot with just one server my nbdswap spaces do start up so I would tend to assume inetd is running.
08:42
and it has a process on the server of course
08:47
I think I possibly found it in the /usr/lib/ltsp/screen.d/ldm file, I am going to assume at the moment my get_hosts script is not returning the proper server list. I will try hardcoding that and see if ldm is able to loop through the servers returned and get the proper info.
08:52etyack has quit IRC
09:01avolkovi has quit IRC
09:03otavio has quit IRC
09:04
<grantk>
semi-success! I was able to log into the server I attempted to have my get_hosts script return when I just hardcoded the entries into the get hosts_script. I had to go with ip's not with a name, even though I defined the nameservers and searchdomain in the lts.conf(no big deal there)
09:04
So one thing I have noticed is that in a bash shell I can run my get_hosts script and the get_hosts script from the ltspManual and get the proper output. But the ltspManual script has errors when it is ran on my ltsp clients. I wonder if this is due to a different shell?
09:07
<Gadi>
what are the errors? (also, I noticed in one of your posts, you have multiple IPs in DNS_SERVER - that does not work in any packaged version of LTSP
09:07
I just added support for that last week
09:07
try with only one IP
09:08
<grantk>
ahh, ok that might get me back. Let me look at the errors again, my memory tends to be horrible at times!
09:09otavio has joined #ltsp
09:12
<grantk>
Gadi: Forward host lookup failed: Hostname lookup failure
09:22CAN-o-SPAM has joined #ltsp

grantk: how is that a shell error?
09:23Q-FUNK has quit IRC
09:24GodFather has joined #ltsp
09:25
<grantk>
no, that is not
09:26
the shell error I am wondering about is why the scripts when ran from the server return the proper information
09:27
but when I rely on the ltsp client to run it nothing is returned that I know of, that is the only reason I can think of that if I hardcode a server list to return it works like one would expect.
09:28
http://pastebin.com/d397c1640
09:30
<Gadi>
your TMP_LIST looks a bit weird
09:30
oh, I see what you are doing
09:31* Gadi wonders if "echo -e" is a bashism
09:31
<Gadi>
romm@bart:~$ echo -e "blah\nblah"
09:31
blah
09:31
blah
09:31
romm@bart:~$ sh
09:31
$ echo -e "blah\nblah"
09:31
-e blah
09:31
blah
09:31
$
09:31
indeed it is
09:32
take out the -e
09:32
<grantk>
ok
09:32alkisg has joined #ltsp
09:33
<grantk>
that may leave me with some newline chars in the list though.
09:36
gadi: Still leads back to the same issue as before.
09:37
<Gadi>
make it: RETURN_LIST=$(echo $TMP_LIST | sort -r | cut -d_ -f2) ; echo $RETURN_LIST|tr '\n' ' '
09:42shawnp0wers has joined #ltsp
09:44
<grantk>
Gadi: on that second line are those all single quotes?
09:44
<Gadi>
after the tr?
09:44
<grantk>
yes
09:44
<Gadi>
yes
09:45
that translates \n to ' '
09:45
<grantk>
cool, having trouble on my end telling if there were any backticks in there
09:45
<alkisg>
Doesn't `echo $RETURN_LIST` already strip all newlines? (if used with a "normal" $IFS)?
09:45
<Gadi>
alkisg: not the way this is coded
09:45
<alkisg>
Ah, ok
09:45
<Gadi>
(I think)
09:45
<alkisg>
I thought echo $x with IFS=' \t\n' consolidated any spacing...
09:46
(as opposed to echo "$x")
09:46* Gadi thinks ltsp-devs need to write a book on shell :)
09:46
<alkisg>
:D
09:46
<Gadi>
I don't think anyone puts dash through its paces as much as we do
09:47
<alkisg>
Right, I've been comparing ltsp to what I see in /usr/bin/*, and you guys are doing an excellent job...
09:47
The only thing I disagree is the 4-spaces guideline :)
09:47
This way we lose the shell feature that strips tabs... <<<
09:49
Errr, <<-
10:15gnunux has quit IRC
10:20
<grantk>
sorry, got called away. When I try to use those modifications I get one server returned out of the two.
10:21
<Gadi>
pastebot again?
10:21
<grantk>
it returns: 10.0.0.32\n98 so I get the server with the lowest ranking plus newline plus the ranking of the best server.
10:21
sure
10:22
http://pastebin.com/d2fbde373
10:26
<alkisg>
Urgh, bash... :P
10:26
let? wth is let? :D
10:28
<grantk>
alkisg: I am not too clear on it, looked it up this morning. http://ss64.com/bash/let.html
10:29
<Gadi>
http://pastebin.com/m1f23b150
10:29
try that
10:30
<alkisg>
echo $TMP_LIST ==> that would output everything in a single line
10:30
So sort afterwards doesn't make any sense
10:30
Maybe you should use quotes...
10:31
<grantk>
yeah, that is where I was trying to use echo -e to get my newline
10:31
<alkisg>
echo "$TMP_LIST" would be better...
10:31
<grantk>
gadi: still get the output 10.0.0.32\n98
10:35
so the chroot environment is what actually executes the get_hosts script if I understand everything.
10:35
I can use the echo -e in the chroot and it produces the desired results.
10:36
<alkisg>
grantk: can you provide some sample input?
10:37
<grantk>
sure

I included my original script and the modified script you made with the sample input of 10.0.0.32 and 10.0.0.46
10:40* alkisg meant the ldminfod output, sorry...

good morning
10:45
here is an interesting question to start the day off
10:46
using a USB sound card with LTSP
10:46
<alkisg>
grantk: and the point is just to keep the one with the biggest rank? Then you don't need to keep them all.. and if inside the loop would do it better.
10:47
*an
10:47
<grantk>
true
10:47
<alkisg>
if [ "$rank" -gt "$max" ]; ...
10:47
<sbalneav>
dro: Still waiting for the question :)
10:48
<dro>
sbalneav: it's not working, I'm still testing with it, I just pluged it into a regular usb desktop and it did nothing......maybe it's dead
10:48
<sbalneav>
Or:
10:49
/etc/modprobe.d/alsa-base.conf
10:49
# Prevent abnormal drivers from grabbing index 0
10:49
options snd-usb-audio index=-2
10:50
so, in the chroot, you may want to comment out that line in $CHROOT/etc/modprobe.d/alsa-base.conf
10:51
<dro>
sbalneav: ok cool checking that now
10:54
<alkisg>
grantk: for just the "max" server, this might do: http://pastebin.com/m247fe06b
10:54
(untested)
10:55
<grantk>
does from the server, I will rebuild the image and test on the client
11:01
<dro>
sbalneav: success!
11:01
sbalneav: tyvm
11:02
<grantk>
success!
11:02
<alkisg>
Nice :)
11:02
<dro>
grantk: woo!
11:02
<grantk>
yep, I guess the option for a choice was nice, but who am I kidding, they would never use it.
11:02
<alkisg>
grantk: ah, I didn't realize that
11:02
<grantk>
I think I would be the only one who would.
11:02
<alkisg>
Let me modify it for the whole list...
11:03
<grantk>
no problem, I xdmcp in if I am connecting to one of these anyway so I already have that choice.
11:03
<alkisg>
grantk: the format is just the IPs sorted by rank, but without the rank?
11:04
and, on one line or on multiple lines?

11:56
There was a commit about it 2-3 months ago...
11:56
So a recent enough version should support it
11:57
<vbundi>
hey since I've switched over to ubuntu 9.10, I'm getting a tftp timeout error on boot with the VM I am using as a thin client
11:57* alkisg had to use the debian sid's pxelinux.0 to overcome that :(
11:57
<akuepker>
vbundi: are you using gpxe or etherboot?
11:58
<vbundi>
pxe
11:58
<akuepker>
ok. was hoping for the easy answer.
11:58
<vbundi>
alkisg: oh really?
11:58
do people still use etherboot?
11:58
<silvergti>
alkisg: I installed my test version last week, tested with [00:e0:c5:*] and no magic :(
11:58
<alkisg>
Well for my vbox and in 2-3 more cases, yeah...
11:59
silvergti: "test version" == which version?
11:59
<akuepker>
a bunch of our DW terminals still have it.
11:59litlebuda has joined #ltsp
11:59
<silvergti>
alkisg: sorry, badly explain, my test server
12:00
<alkisg>
silvergti: ok, but which ltsp version do you have?
12:00
<silvergti>
5
12:00
<akuepker>
we've had to pull all of them to move to LTSP5 on Karmic. We've been tunning LTSP since 2003-ish, and there's always a few terminals tucked away that we forgot about.
12:00
running, that is
12:00
<vbundi>
wait maybe there is an easier answer
12:00
<alkisg>
silvergti: "(07:55:29 μμ) alkisg: There was a commit about it 2-3 months ago..." ==> is your LTSP version that recent?
12:01
<vbundi>
I can't find tftpd on my system.
12:01
<silvergti>
ltsp-server_5.1.90-0ubuntu3_all.deb
12:01
<vbundi>
I did apt-get install ltsp-server-standalone
12:02
<alkisg>
silvergti: no, that's Karmic, I don't think it supports wildcards.
12:02
<akuepker>
is your dhcpd on the LTSP box?
12:02
<vbundi>
yes
12:02
<alkisg>
silvergti: More recent versions should support wildcards though.
12:03
<vbundi>
should ltsp-server-standalone not add tftp in?
12:03
<silvergti>
alkisg: ok. i will wait for the Ubuntu ppl :) thank you
12:03
<dro>
vbundi: it adds a tftp server but it's named something else....looking it up
12:03
<alkisg>
silvergti: http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/revision/1474
12:04
<vbundi>
oh yea that sounds like ubuntu lol
12:04
<alkisg>
silvergti: any version later than 2009-12-25 supports wildcards. You can find one for karmic in stgraber's ppa.
12:04
<akuepker>
vbundi: tftpd-hpa
12:05
<dro>
vbundi: tftp isn't your issue, it's something else, you done the basics? sudo ltsp-update-sshkeys, sudo ltsp-update-kernels, sudo ltsp-update-image ?
12:05
vbundi: could also be your path, you do anything weird in your dhcpd.conf file or change any paths for the *.img ?
12:07
<vbundi>
dro: yea I've ran ltsp-update-xxx, haven't changed anything in my path afiak
12:07

It runs from inetd

12:08
ah that makes sense
12:08
<alkisg>
Don't change your setup...
12:08
grep tftp /etc/inetd.conf to see it
12:09

tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot
12:09

vbundi: never hurts to double check.....time to start over :)
12:13

12:15

that is awesome. I'll test it out today

12:22

Gadi: I think so.
12:22

cool
12:22
lemme know how it goes
12:23
<Lns>
will do
12:27
Gadi: ok you know i'm on 8.04, was this dir changed in more recent versions? ${MENU_APPEND_PATH:-"/usr/share/ltsp/screen.d/"} --- I think mine is /usr/lib/ltsp/screen.d
12:30
<Gadi>
yes it was
12:30
you can mod the script

or symlink the dir

just making sure =)
12:38

hey what are the minimum requirements for ltsp 5 terminals nowadays? my Neoware terminals with 24MB ram are kernel panic'ing from running out of memory
12:53rhodan has joined #ltsp

<Lns>
vbundi: personally i wouldn't run a terminal with less than 512..but you might be able to get away with 256 depending on what you're expecting of it
12:54
or maybe even 128
12:55
<vbundi>
lns: yowza. These things have been running ltsp 4 connecting to windows 2k3 for years with 28MB
12:55* alkisg is using 64mb terminals without problems
12:56
<Lns>
vbundi: ltsp5 is a much different (read: updated) beast
12:56
alkisg: you're not running OOo or FF are you ;)
12:56

Lns, sure
12:56
OOo, FF, videos, wine, you name it

Nope

how do you get around the pixmap fiasco?
12:57
<vbundi>
alkisg: are you running ubuntu? and what ver
12:57
<alkisg>
I don't think it uses pixmaps if it doesn't have enough free ram...
12:57
vbundi: yes, well on those terminals I've tried from 7.04 to 10.04
12:58
<vbundi>
wow
12:58* Lns stands corrected..
12:58
<alkisg>
Of course I don't install anything on the chroot, apart from the langpacks and sometimes sshd
12:59
But I do have nbd swapping or a local swap partition enabled...
13:00
(nbd_swap isn't enabled by default, unless 48 Mb RAM or less are detected ... maybe we should increase that to 64 nowadays...)
13:00
<vbundi>
well thanks to dro, I've got my newer terminals booting great... wow is 9.10 is much faster than 8.04 on boot

why's LTSP5 so much more resource hungry over LTSP4... hardware support, LDM or what?
13:06

13:06

newer kernels
13:06

yeah.. it's not ltsp.. it's the OS
13:06
the whole thing
13:07
<vbundi>
oh yeah I guess the clients are running newer kernels
13:07
<johnny>
the OS in ltsp4 is quite old
13:07
the entire chroot OS was uhmm.. how old?
13:07
5 years?
13:07
4?
13:07
<vbundi>
well my ltsp 4 install is runnign 2.4.x
13:07
<johnny>
2.4 is dead
13:07
<vbundi>
yeah
13:07

2.4 was certainly a bit better at such things
13:08
<Lns>
ipcop still uses it ;) but not for long actually
13:08
<vbundi>
I can't even use newer mice, I only get Y-axis movement
13:08
ipcop is moving to 2.6???
13:08

yup, in 2.0 series
13:08
new web ui and everything =)

i don't even know it's directly ltsp related
13:09
using ubuntu904
13:09
and they end up with like a 10gig dev dir :\

and then they yell at me cause the machine runs outta space

anyone ever heard of something like that? google is failing me

13:58

is the server configured to allow passwords?
13:58
i.e. keys only?

14:45
<knipwim>
johnny: can you explain the post_unpack_stage_tarball function in the quickstart profile?
14:46
specifically why the LOCALE is checked, but not used if /etc/env.d/02locale exists
14:46
<johnny>
because we are just going to copy it over iirc
14:46
<dro>
vbundi: how long?
14:47
<johnny>
there is no definitive place to put those vars in gentoo last time i looked
14:48
<knipwim>
/etc/env.d/02locale is the right place, and locale.gen
14:48
<johnny>
the goal is to pass a locale if we got one
14:48
<knipwim>
but wouldn't you copy it only if LOCALE is not set?
14:48
and the source file exitsts of course
14:48
<johnny>
no, if it's set, we want to add it
14:48
<knipwim>
and override the custom setting?
14:49
if it's there?
14:49
<johnny>
no.. we should be adding the custom setting :)
14:49
that was the goal anyways.. i never tested it..

CAN-o-SPAM: I just had an impromptu meeting with our director. He seems keen on the LTSP route, in part because we get to use our existing PCs as terminals, until they die or we can afford to replace them.
15:30
...now all I have to do is figure out what we're going to use for servers.
15:31
<CAN-o-SPAM>
ball: thats great ... +1 for LTSP again! :)
15:31* ball nods
15:32
<vagrantc>
and with recent versions of ltsp... the options get even more confusing... if your clients are powerful enough, you can run some apps locally... or all apps locally... or none of them locally.
15:33
localapps or fatclients can really decrease the need for bad-ass servers.
15:33
<Lns>
or fatclients with remote apps
15:34
<alkisg>
And on LTSP version 15, we'll even be able to run openoffice on PC1, firefox on PC2, and evolution on whatever PC has the lowest CPU usage currently... :P
15:34

alkisg: client load balancing?
15:35

15:35

15:35

OR, you could use all of the clients in a cluster, acting as the server as well.
15:35
I think that's due in v20

i was going to package some up in a chroot and boot it over there (no pun intended) ;)
15:59
<sbalneav>
Lns: I use mutt.
15:59
<Gadi>
Lns: sorry - got caught up in other things - what distro were you testing the ssh stuff on?

<sbalneav>
The One True Mail User Agent

sbalneav: hehe, I used to use pine.. I'm admittedly too scared to try mutt for anything more than tinkering, but i do have imap so i guess it wouldn't hurt anything =)
16:01
I've fallen in love with Thunderbird back when it was Netscape Mail though
16:01
<sbalneav>
irssi for irc, mutt for mail, procmail for filtering. Guis? What are they?
16:01
<Lns>
Gadi: ubu 8.04 ;)
16:01
<ball>
sbalneav: Need X for xneko though.
16:01
<Gadi>
Lns: are you still in a testing mood?
16:01
<Lns>
Gadi: sure
16:02
Gadi: i replaced the /usr/share dir in the ssh script btw
16:02
<Gadi>
can you: echo ${TTY} >/tmp/debug
16:02
in that file
16:02
and then check the value
16:02
from a shell
16:02
<sbalneav>
heh, here I am with all this amazing graphical power
16:03
I got 14 gnome-terminals loaded, one Epiphany window :)
16:03
<CAN-o-SPAM>
heh
16:03* Gadi thinks he should have kept all that old weird TTY code from the telnet script :P
16:03
<Lns>
Gadi: nothing in there =)
16:03
<Gadi>
grr...
16:03
can you copy the necessary TTY code from the telnet script?
16:04
:)
16:04
<Lns>
sbalneav: that's what x is for..multiple terminal windows =)
16:04
Gadi: sure
16:04
<sbalneav>
Lns: My sentiments exactly
16:04* Gadi thinks in newer versions, we figure out TTY in ltsp_Config
16:04
<Gadi>
or somewhere else
16:05
<sbalneav>
I still use rtin to read usenet
16:06
<Lns>
but the news said usenet was dead! =p
16:06

heh

brb, gonna go grab a sandwich across the street - gadi, image is rebuilding

Gadi: still no go, but this time the term seemed a bit "nicer" (chars weren't off to the left, I'm thinking the tty code worked at least).. but still, have to c+a+f7, and ssh denies me thrice after entering in username
16:29
<Gadi>
Lns: can I see the script you have atm?
16:30* Gadi thinks we may need to call: ssh .... <${TTY}
16:30
<Lns>
sure
16:30
<Gadi>
see, we have gone back and forth between calling the sessions with openvt and without
16:30
<Lns>
hmm, no more ltsp pastebot?
16:30
<Gadi>
depending on how u call it, u may not be attached to the tty

ok, I did a few silly things there
16:34
but, first can you add the echo ${TTY} > /tmp/debug
16:34
and change USER to SSH_USER
16:34
USER is a horrible thing for me to use
16:34

lemme check tty

16:44
i think we gotta strip tty out for chvt
16:44
<Gadi>
ah, right you are
16:45* Lns wonders how it worked for telnet script...
16:45
<Gadi>
chvt ${TTY##tty}
16:45
I think
16:45
lemme check
16:45
cool
16:45
got it in one
16:45
well, one of many
16:45
:)
16:45
<Lns>
hehe
16:45
<Gadi>
ok, so that takes care of that
16:46
<Lns>
so replace it w/ ^^ ?
16:46
<Gadi>
now, we probably need at the end of the ssh line: < ${TTY}
16:46
<Lns>
ok
16:47
<Gadi>
http://pastebin.com/m4e2601e8

rebuilding
16:50
<Gadi>
oh, wait
16:50
that wont work
16:51
it needs to </dev/${TTY}
16:51
sorry
16:51
<Lns>
oops, ok
16:51
=)
16:52
hmmmm
16:52* Lns wonders, as his -update-image runs for ~2min each time..is there a way to find out what bits have changed in the filesystem and only update the image that way? kinda like what rsync does for files?

17:09

Gadi: how come it fails 3x when the ssh line isn't in a loop?
17:09
<Gadi>
Lns: ssh by default prompt three times for a password
17:09
<Lns>
right
17:10
<Gadi>
did it take the Username line properly?
17:11
<Lns>
it asked me, yeah - put in my ltsp server username, that's when it gives me "Permission denied" 3 times
17:11
after about 3 seconds of delay
17:11
hmm
17:11
3 seconds... it couldn't have anything to do w/host keys ?
17:12
and/or name resolution?

the server or the thin client?

Well, from what I understand, it's the driver that reports the current orientation of the monitor incorrectly, so ltsp tries to "flip" it to fix it

well, compiz can be disable easliy. is this per user or server based?
19:47
it's really a matter of un-installing it
19:47
<sbalneav>
both methods are server wide :)
19:47
I prefer the uninstall method myself.
19:47
<Ahmuck>
has anybody determined if it affects user by user or if it effects server wide?

I think it affects server wide, intermittantly\

any reason a user shouldn't log in directly at the server, or should all my users be on their own clients?

My servers all tend to be in back rooms, so the user's cant log in on 'em.

they will be logged in as a user, and they don't have physical access to the server
