alkisg: LTSP should be up to date in my PPA (trunk snapshot)

<alkisg>
Thanks stgraber, will test more today, but I believe it's in a very good shape to send a snapshot to precise too
05:08
<stgraber>
ok, cool. I may tag 5.3.5 tomorrow then
05:15
<alkisg>
Putting "group = disk" in /etc/nbd-server/config allows for using qemu-nbd to directly export a vbox .vdi disk as a (fat) chroot. Would it hurt to use it by default instead of nogroup?

@alkisg what might be the problem witn epoptes - getting "epoptes-client ERROR: Failed to fetch certificate from server:789" on command "epoptes-clinet -c" in chroot
06:10komunista has joined IRC (komunista!~slavko@adsl-195-168-242-217.dynamic.nextra.sk)
06:10
<alkisg>
srdjo: that's weird, it should be trying from localhost
06:10
srdjo: I've heard about this problem, but I've never seen it, mind if we shared a screen for me to see it?
06:11
If you don't mind, go to the epoptes help menu > remote support, and put my ip there: alkisg.dyndns.org
06:13
If you do mind, then just enter: epoptes-client -c localhost
06:13
That should do it
06:14
<srdjo>
I dont mind - I just cant add myself to the group to run epoptes
06:14
<alkisg>
srdjo: ah, ok, easier way then: x11vnc -connect alkisg.dyndns.org

06:18
<alkisg>
srdjo: it worked fine for me, what were you doing?
06:18
The second time I did it from the server, not from the chroot, and that's why it didn't work, did you do that?
06:19
<srdjo>
no I did not
06:19
you can scrool the window and see it your self
06:20
It look like it did
06:20
but how it exited from chroot ?
06:20bauerski has joined IRC (bauerski!~witekb@frodo.psp.opole.pl)
06:21
<alkisg>
I can't scroll up enough to see it
06:21
srdjo: you need to run ltsp-update-image now, before booting the clients
06:21
Also, until you logout, you won't be able to run epoptes from the menu because for the group change to take effect you'd need to logout
06:21
I ran it from the console with "newgrp" for you
06:22* alkisg left vnc...
06:35
<alkisg>
srdjo: thank you, I suspect the problem is related to sourcing the "ltsp_config" while chrooted
06:35
That's done to decide if the client is a thin or a fat one etc, but it shouldn't be done at all while in a chroot
06:36
I got the needed shell trace, I'll fix it later on
06:36
<srdjo>
I just dont know how it worked for you the first time :)
06:36
can I build the image now ?
06:36
<alkisg>
I didn't use -p -c
06:37
<srdjo>
neither did I in the second terminal
06:37
<alkisg>
Hmmm weird
06:37
Anyway I think I'll be able to solve it with the trace
06:37
Yes, you can run ltsp-update-image now
06:38
<srdjo>
ok - thanks
06:38
<alkisg>
Thank you too

alkisg, I am still struggling with cups script
08:34
I named it I02-check-printer
08:34
here is the content
08:34
if [ -n "$STAMPAC"]; then
08:34
cp /home/config/cupsd.conf /etc/cups/cupsd.conf
08:34
/etc/init.d/cups restart
08:34
fi
08:35
i mounted home using NFS_HOME
08:35
<alkisg>
srdjo: run sh -n I02-check-printer
08:35
I think you forgot a space before ]

sh: can't open I02-check-printer
08:47
<alkisg>
Well, put the full path so that it finds it
08:49
<srdjo>
I can run it with full path and it doesn't give any errors, but it also does nothing
08:50
<alkisg>
Can you upload it to pastebin?
08:50
<srdjo>
script ?
08:50
<alkisg>
Yes

08:51
yes
08:51

08:51

08:51
^ the difference there is because of the space before the ]
08:52
<srdjo>
here is the script
08:52
http://pastebin.com/bnqhQZDn
08:52
i will try to add space
08:53bobby_C has joined IRC (bobby_C!~bobby@chello080108221029.1.13.vie.surfer.at)
08:56
<srdjo>
space did not change anything
08:58
commands work if i run them one by one
08:58
But "if" is the problem
08:59
<Hyperbyte>
srdjo, are you sure $STAMPAC isn't the problem?
09:00
<alkisg>
The space part was a syntax error, but fixing one syntax error doesn't mean that your script does what you want now. /me is in the middle of some coding, leaves it up to Hyperbyte ;)
09:01
<Hyperbyte>
srdjo, what's the purpose of the $STAMPAC variable?
09:01
<srdjo>
here is my ltsp.conf
09:01
[08:00:27:94:0d:10]
09:01
STAMPAC=True
09:01
<Hyperbyte>
Okay
09:01
<srdjo>
Stampac means printer in serbian
09:01
<Hyperbyte>
Get rid of the STAMPAC variable
09:01
<srdjo>
if printer is true
09:01
<Hyperbyte>
In the script, remove the 'if', in the lts.conf remove the STAMPAC=True
09:02
Rather just only put the RC_FILE_01 lines for the clients that need it.
09:02
So [08:00:27:94:0d:10], RC_FILE_01=...
09:02
<srdjo>
what would be rc_file_01 ? Script ?
09:02
<Hyperbyte>
And don't put spaces in front of lines in lts.conf
09:03
srdjo, yes.
09:03
!lts.conf
09:03
<ltsp>
Hyperbyte: lts.conf: http://manpages.ubuntu.com/lts.conf
09:03
<Hyperbyte>
See that please.
09:03
alkisg - RC_FILE_N isn't documented?
09:03
<alkisg>
RCFILE_01, I told him to try that a couple of days ago, he said it didn't work
09:03
<Hyperbyte>
Oh
09:03
It's RCFILE_01
09:04* alkisg believes he did something wrong though
09:04
<Hyperbyte>
alkisg, I told him to configure CUPS on the server, with all printers from clients using jetpipe, and then tell all clients to use CUPS on the LTSP server for printing - wouldn't that be the best way?
09:04
<alkisg>
Well, if one uses fat clients, I think it's best if he uses CUPS for it
09:05
We indeed lack proper cups support for fat clients though, so... :)
09:05
<srdjo>
Hyperbyte, that also did not work
09:05
<alkisg>
It's in the TODO list
09:05
<Hyperbyte>
alkisg, okay, so he needs ro run CUPS on every client?
09:05
<srdjo>
alkisg, we tried puting cupsctl command in RCFILE
09:06
just on the ones with local printers
09:06
<Hyperbyte>
srdjo, I'll help you in a bit - let me discuss with alkisg a little bit please first. :-)
09:06
<srdjo>
others use ltsp server cups
09:06
<alkisg>
Hyperbyte: cupsd runs on every fat client anyway
09:06
(and on any standalone client as well)
09:06
<Hyperbyte>
alkisg, okay, so, we use that cups.
09:06
<alkisg>
But printer sharing is not enabled by default
09:07
So "cupsctl --enable-sharing" or something needs to be called on boot
09:07
<Hyperbyte>
Okay
09:07
<srdjo>
and printers get reinstalled on every boot
09:07
<alkisg>
(in the future, we could map that to an ltsp variable)
09:07
But srdjo needs something special now
09:07
<Hyperbyte>
srdjo, let me guess
09:07
<alkisg>
He needs to specify an A4 paper size or something
09:07
So he needs a custom cupsd.conf
09:07
<Hyperbyte>
Ah
09:07
Okay
09:07
Thanks
09:07
<alkisg>
We'd support that like we do X_CONF=file
09:07
<Hyperbyte>
I help now.
09:07
:)
09:08
<alkisg>
So we'd copy that on boot, before cups starts
09:08
OK, /me goes back to coding...
09:09
<Hyperbyte>
srdjo, few comments
09:09
The directory /home/config/ for storing configuration is very bad.
09:09
<srdjo>
Hyperbyte, I already have the cups.conf part covered, just need a way to copy it on boot
09:09
what should i use
09:09
?
09:10
<Hyperbyte>
srdjo, okay, I see we need to get back to basics.
09:10
If you want me to help you, I want you to listen to everything I say, and adjust your system accordingly. Don't say "I got it covered" please, because if you did, it'd be working.
09:10
First, don't use /home/config/. Configuration is stored in /etc/
09:11
Make a cups.conf which is the default, and a cups.stampac.conf for the other clients that need it
09:11
<srdjo>
ok, but I needed a folder that I can change without rebuilding the image - isnt /etc/ in chroot ?
09:11
<Hyperbyte>
(this all has to be inside the chroot of course)
09:11
srdjo, why without rebuilding the image?
09:12
<srdjo>
just tough it would be faster to make changes if needed
09:12
<Hyperbyte>
Bad idea.
09:13
Put them in /etc/, /home/ is for user files, not config. You create other problems if you break that logic.
09:13
So cups.conf for default, cups.stampac.conf for the special PC's
09:14
<srdjo>
ok - did that
09:14
<Hyperbyte>
Then create a script in /usr/bin/ called "cups-stampac"
09:15
That script does "cp -f /etc/cups.stampac.conf /etc/cups.conf"
09:15
And "/etc/init.d/cups restart"
09:15
Make sure you chmod +x the script
09:15
Then run ltsp-update-image
09:16
And then adjust your lts.conf to contain RCFILE_01=/usr/bin/cups-stampac for every client that needs it.
09:17
Oh, put #!/bin/sh on top of the cups-stampac script

09:21
<alkisg>
OK now epoptes supports XDMCP users too ;)
09:22
<Hyperbyte>
alkisg, you rock!
09:22
I'll probably be switching to 12.04 in the future (I know I know, if it ain't broken.... but I can't resist)000000000
09:22
I'll definitely be trying out epoptes. :-)
09:25
<alkisg>
Trying out epoptes is easy now (10.04+) too, you just install it ;)
09:26
<Hyperbyte>
Yeah, but I don't wanna experiment too much with my production system, unless it's necessary.
09:26
When I install a new server, it'll be a good opportunity to experiment.
09:26
Or 'experiment'... let's call it 'try things out'

10:02
it did not work because we messed up the cups directory and file name :)

/etc/cups.conf should be /etc/cups/cupsd.conf
10:03
will try it again :)
10:03

nxo, if you run your mail client as local application, definitely.
12:25
<nxo>
Hyperbyte, right, that would be a way. I'll play with that. but there is nothing to forward it to the server, right? Another great thing would be using it for ssh.
12:26
<Hyperbyte>
nxo, LTSP interfaces USB devices with a filesystem by default.
12:26
The rest you'll have to interface yourself.
12:27
"by default" -> "out of the box"
12:30
<nxo>
Hyperbyte, ok, thanks. smartcard integration would be a great feature though. ;)

Hyperbyte, there seems to be usbip (usb voer IP). I'll look into that when I'll find some time.
12:51
<Hyperbyte>
nxo, that'll interface the numerous smartcards around your network all with the server. That's nice, but you'd have to figure out a way to get it, not only over IP, but also tied into the user session.
12:52
<nxo>
Hyperbyte, yes, but as I know which terminal a user is logged on to there might be a way. I don't want others on my smartcard anyway ;)
12:53bobby_C has joined IRC (bobby_C!~bobby@85-124-22-227.teleworker.xdsl-line.inode.at)
12:53
<nxo>
so there would have to be some kind of access control. hmm. well, I'll see.
12:56
<Hyperbyte>
nxo. so it's interface to get device from client to server, then access control to make it only available to user logged in to the client the device comes from, and then some magic to tell the apps on the server -which- device they need to access
12:57
Localapp seems like the way to go. :-)
12:58
There could be some magic ready for you to take care of smart cards though, I definitely don't know everything there is to know about LTSP.
12:58
<nxo>
Hyperbyte, oh, yes, the last part as well.
12:59
and the smartcard lib might not support infinite numbers of etokens.
12:59
<Hyperbyte>
nxo, LDM does have some autologin configuration variables.
13:00
You could write the username/password on the smartcard, and pass those values to LDM.
13:00
You'd create a program to run after LTSP has started up, but before the LTSP login manager
13:00
<nxo>
so login an mail as local app should be doable. but ssh out on the server using the cert on the etoken probably isn't
13:00
<Hyperbyte>
Only serious problem would be that anyone with a smartcard reader, can figure out username/password and just enter those into the system and be done.
13:01
<nxo>
Hyperbyte, there are some ldap mapping ways for users/certs

<srdjo>
Hyperbyte, in home directory i have a directory "Shared" that everyone can write to and read from. What would be the easiest way of mounting it to my client (I am currently using NFS_HOME, but then all users home folders are visible)
13:39
<Hyperbyte>
srdjo, create a folder /data/ for your shared files, and mount that folder instead.
13:39
You can do it via <chroot>/etc/fstab and NFS, it'll be mounted during startup of the client.
13:41
<srdjo>
great, I will do it that way - I forgot that chroot had fstab - thanks again

17:24
UDS, not BTS
17:24
<ogra_>
oh, i misread !
17:24
<stgraber>
the UDS in May is in California instead of Europe, so not sure how it'll affect the October UDS
17:24
<ogra_>
no, no idea yet
17:24
<jammcq>
yeah, those TLA's are confusing
17:24
hmm, at google?
17:25
<ogra_>
we did them alternating in the past ... us ... europe ...
17:25
<stgraber>
nope, in Oakland
17:25
<ogra_>
but at some point we had two in a row at one place ... since then that schema is broken a bit
17:26
so its hard to predict if the october one will even be in the us
17:26rthomson has joined IRC (rthomson!~rthomson@mars.pet.ubc.ca)
17:27
<stgraber>
yeah, for me at least BTS is easy to get to even if UDS is in Europe (as long as I can convince highvoltage or mgariepy to drive me there) but having the October UDS outside the US would make it a bit harder for the Europeans to attend I guess (or at least quite a bit more expensive)
17:27
<ogra_>
well
17:28
i have enough miles under my belt for a free transatlantic flight ...
17:28
i saved them for exactly that case ;)
17:28
<jammcq>
when I visit scotty starting May 25th, we'll begin the process of nailing down a date for BTS. maybe the UDS schedule will be known at that time
17:28
<ogra_>
and i did one BTS completely on my own dime, was around 500€ for a round trip including the rental car
17:29* jammcq wishes he could do a Euro symbol too :)
17:29

get a proper keyboard ;)

I actually have a german keyboard at home. I bought it for ltsp testing

devan: ram and cpu needed directly depend on what's going to be run in the clients

and if you don't have any network sniffing concerns, turn on the direct_x, will take some load off the cpu's and speed things up too

thats not an issue actually I have 15 clients connected to 1 server , I want to add 3 more servers and 30 clients accordingly to the same server, I want to know the best possible way

I should really test a thin client capable of 3d+unity (recent intel hardware) and see if 3D works in that case

but everything else should now automatically fallback to 2d with the builtin check in unity
18:41
<alkisg>
So, next TODOs are... policy-rc.d and start-stop-daemon handled by ltsp-chroot, allow ltsp-client + ltsp-server to be installed in parallel, support the lubuntu-ldm-theme... and maybe write a new utility, ltsp-publish-image, that helps exporting vbox/qemu/btrfs-loop images as squashfs nbd exported images (but that one might not go to precise...)
18:42
Anything else for precise?
18:43
I think currently any normal Ubuntu installation can become an "ltsp chroot" by just installing ltsp-client, it should be ready
18:46

Hi!

hi Hyperbyte
22:46
Hyperbyte, is it possible to just copy image from one ltsp server to another and use it without configuring everything again ?
22:50
<||cw>
is it going to have the same IP address?
22:50
you can probably copy the chroot and build the image again
22:51
<srdjo>
I have 4 ltsp servers on 4 places
22:52
and they are all the same except for the ip addresses
22:53
what would be the easiest way to "synchronize" chroots ? copying ?
22:56
<||cw>
rsync maybe
22:57

srdjo, definitely rsync. Also, you'll want to...

Hyperbyte: ltsp-update-image: If you use NBD (e.g. Ubuntu), every time you change something in your chroot (e.g. /opt/ltsp/i386), you need to run ltsp-update-image and reboot the thin clients for the changes to take effect

<Hyperbyte>
No
22:58
You'll want to...

!update-sshkeys

Hyperbyte: I do not know about 'update-sshkeys', but I do know about these similar topics: 'ltsp-update-sshkeys'
22:58
<Hyperbyte>
!ltsp-update-sshkeys
22:58
<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

what would be the best source for rsync ? ftp server or is there something better ?
22:59
<Hyperbyte>
You could also create a harddisk image of the working server, and write it to the new server.
22:59
rsync usually works via ssh. rsync root@server1:/opt/ root@server2:/opt/
22:59
<srdjo>
yes, but I would have to go to that server physically
23:02
i could write a cronejob script that would call rsync and run ltsp-update-image every night (only if changes are made of course)
23:02
<Hyperbyte>
I would personally make a master update script which you run manually
23:02
You'll need to run ltsp-update-image for one server anyways
23:02
Might as well create one big script which does an rsync on the chroot to all servers
23:03
And then runs ltsp-update-image on these servers.
23:03
But

Before you're gonna reinvent the wheel
23:03
You do know about LTSP-Cluster, right?

<srdjo>
did see it before but word cluster made me think it was meant for a group of server at one location
23:07
can it be used in my scenario ?
23:07
4 servers - 3 towns
