<sebas891>
hi folks, LTSP is a great projet!
11:14
<cyberorg>
sebas891, yes it is :)
11:14
<sebas891>
I would like to customize the ldm login screen, specially move the login prompt.
11:14
<cyberorg>
sebas891, what distro?
11:15
<sebas891>
I looked in the greeter-gtkrc but I cannot get a clue on how to do it.
11:15
I use ubuntu 9.04
11:15
<cyberorg>
ah, you found the place, you will have to play with gtkrc
11:16
<sebas891>
actually, I've always seen login prompt right in the middle of the screen. ...
11:16
it is possible to do without hacking the c code of greeter.c ?
11:17
<cyberorg>
look in gtkgreet/greeter.c
11:17
yes, see lw, lh
11:17
<sebas891>
I know nothing about c, unfortunately.
11:18
lw lh I saw that.
11:18
<cyberorg>
well you are almost there, trial and error is a way to go
11:19
<sebas891>
i guess :)
11:19
with a little recompyling... in between.
11:19
<cyberorg>
or ogra and sbalneav may know more if you still cannot figure it out
11:19
<sebas891>
if (lw < 180) lw = 180;
11:19
<cyberorg>
use nfs instead of nbd when experimenting
11:20
<sebas891>
I did try on a standalone machine with the package installed.
11:20
<cyberorg>
./configure --prefix=/usr && make && make DESTDIR=/your/chroot/path install
11:21
<sebas891>
that was the easiest setup I could come up :)
11:21
<cyberorg>
something like that should install new ldm in chroot, use the chroot as nfs exported image
11:22
<sebas891>
the thing, if I hack the code rigth in the c file, I'll to maintain a patch with the next upgrade :(
11:24
<cyberorg>
sebas891, that part of code never changes
11:26
<sebas891>
Is there another option? like not using ldm and using X ?
11:26
<cyberorg>
no, ldm is what makes up most of ltsp
11:26
<sebas891>
is sdm worth looking at it? will I be able to customise it?
11:27
<cyberorg>
all ltsp features are dependent on ldm, without it there is no ltsp :)
11:27
<sebas891>
ok :)
11:28
I had a really nice background picture, that needed the logging more at the top of the screen.
11:28
I'll have to change that i'm afraid.
11:29
<cyberorg>
if you do write a patch that makes ldm customizable via lts.conf variable such as LDM_INPUT_LOCATION=(top, bottom, left, right, center) may get accepted :)
11:30
<sebas891>
:)
11:30nlebrun234 has left #ltsp
11:31
<sebas891>
LDM_INPUT_LOCATION=(x,y) may be better
11:31
<cyberorg>
yeah
11:32
<sebas891>
x,y (% of the screen) sort of thing.
11:33
<Ryan52>
ldm will eventually have support for that.
11:33
(I think)
11:33
<sebas891>
is there some variable that are passed to greeter.c ?
11:33
<Ryan52>
not yet.
11:34
<sebas891>
Ryan52: is there something somewhere I could try ?
11:34
<Ryan52>
do what cyberorg suggested..
11:47nlebrun234 has joined #ltsp
11:48
<sebas891>
cyberorg Ryan52 thanks for the clues about how to change the login location. I don't know .c to make a valid contribution.
11:49
I'm working more on deploiment of ltsp servers using puppet
11:49
<cyberorg>
sebas891, well you have at least easy task to do and most of the code is in place ;)
11:49
<sebas891>
hehehe.
11:50
<cyberorg>
interesting, can you elaborate what exactly are you doing?
11:52
<sebas891>
i've to install multiples ltsp servers in a few location. I want to automate the installation and configuration process of an ltsp server.
11:52
not that it's few complicated to install a ltsp server, but there is nothing like automating it :)
11:53
I installed the machine using debian/ubuntu preseed install method with pxe/netboot.
11:53
<cyberorg>
cool, do share docs somewhere on blog or wiki when you are done
11:55
sebas891, on opensuse we have rpm package with prebuilt ltsp image, that makes deploying easier :)
11:55
<sebas891>
for example this is the puppet recipe to install/config an ltsp https://trac.redcta.org.ar/redcta/browser/trunk/puppet/manifests/classes/ltsp.pp
11:56
that is a little documentation of the "server" which has more than the ltsp service :) https://trac.redcta.org.ar/redcta/wiki/ServidorRedLocalMultiServicios

<sebas891>
puppet helps you manage configuration of machines, very usefull when you've many of them.
12:00
we all know that doing the package install of the ltsp-server is the easy part, there is always a lots of details to take care of after...
12:04
<cyberorg>
sebas891, we have giant shell script http://bazaar.launchpad.net/~jigish-gohil/kiwi-ltsp/trunk/annotate/head%3A/trunk/kiwi-ltsp/ltsp/include/kiwi-ltsp-functions.sh
12:04
<sebas891>
actually, I should do a puppet module to install and ltsp-server.
12:04
<cyberorg>
http://bazaar.launchpad.net/~jigish-gohil/kiwi-ltsp/trunk/annotate/head%3A/trunk/kiwi-ltsp/ltsp/include/kiwi-ltsp-setup
12:04
second script takes various switches to do configurations

<sebas891>
interesting.
12:10johnny has left #ltsp
12:11
<sebas891>
cyberorg: with puppet, it would be possible to have the task multi distribution.
12:11johnny has joined #ltsp
12:11
<cyberorg>
yeah looks quite interesting
12:11
<Ahmuck_>
puppet?
12:12
with puppet?
12:12
i'm late to the conversation
12:12
<nubae>
sebas891, yeah a puppet module for ltsp server would awsome
12:12
<Ahmuck_>
what would a puppet module do for ltsp?
12:12
<nubae>
though in that case it should take cluste into consideration
12:13
<Ahmuck_>
http://www.ocsinventory-ng.org/ - would this program inventory the client hardware?
12:15
<sebas891>
puppet would install the ltsp-server other possible packages, build the client (if you have a proxy of packages, would use it for example)
12:16
puppet would make sure that the tftpd service is running.
12:17
<Ahmuck_>
i need to rebuild the thin client after a system upgrade. do i need to delete the old client build?
12:18
ie, rm -rf /opt/ltsp/i386
12:18
and rm -rf /opt/ltsp/images?
12:19
then sudo ltsp-build-client?
12:19
<sebas891>
you don't have to delete the image.
12:19
it's overwritten.
12:20
rm -rf /opt/ltsp/i386 ???
12:20
you will delete the base of your client... why would you do that?
12:21johnny has left #ltsp
12:21
<Ahmuck_>
wouldn't the base be rebuilt upon ltsp-build-client?
12:21johnny has joined #ltsp
12:21
<sebas891>
Ahmuck_: use ltsp-update-image to update the client.
12:22
ltsp-build-client, is only of the very first time you put in place the ltsp service.
12:22
<Ahmuck_>
so, upgrading the ubuntu distro from 9.04 to 9.10, then all i need to do is update-image
12:22
sebas891: k
12:22
<sebas891>
Ahmuck_: ah! no.
12:23
<Ahmuck_>
NOTE: Root directory /opt/ltsp/i386 already exists, this will lead to problems, please remove it before trying again. Exiting.
12:23
error: LTSP client installation ended abnormally
12:23
<sebas891>
if you upgrade between release, you'll have to do a ltsp-build-client I guess.
12:24
Ahmuck_: did you make changes in the client?
12:25
<johnny>
hmm.. that's what wwe need.. a directory of changes we make to the chroot that will overlay the entire thing
12:25
so /opt/ltsp/i386-modifications or somethin
12:25
or sommewehere.. that will copy the files we need..
12:28
<Ahmuck_>
http://www.ocsinventory-ng.org/ - i've used this to inventory large installations of large computers. can this be used to inventory thin client hardware? would each thin client report?
12:35
<johnny>
why not?
12:35
you'd need to install something in the chroot i imagine
12:35
it's just a linux box.. so i don't see why not
12:37jbicha has quit IRC
12:39
<sebas891>
Ahmuck_: ocsinventory works with thin client, that problem I had was that all the client had the same hostname...
12:40
<Ahmuck_>
osc invetories by ip address?
12:40
<sebas891>
i'm about to install it under ubuntu 9.04.
12:40
<Ahmuck_>
ok
12:40
sebas891: any other inventory program that you know of that has it's detail?
12:40
<sebas891>
that is a oscinventory question :)
12:41
<Ahmuck_>
johnny: in chroot?
12:41
<sebas891>
no, I don't
12:41
know.
12:41
<Ahmuck_>
i'm about to rebuild the thin client
12:41
johnny: ok, i understand
12:41
i'd need to install the client side in the chroot
12:41
<johnny>
sebas891, which version of ubuntu/yourdistro
12:41
<sebas891>
the nice thing about the ocsinventory is the integration with glpi.
12:42
<johnny>
ubuntu should now make fake hostnames if you don't set one on dhcp
12:42
<sebas891>
johnny: that I had problems with? (ubuntu 7.10)
12:42
<johnny>
that's why
12:42
<Ahmuck_>
inventoring hardware on the thin clients would allow me to target specific clients for upgrade
12:42
<johnny>
you should have set dns hostnames for them
12:42
but now.. you don't need to
12:42
it will assign a name+num for them automatically if htere is no assigned hostname by dhcp for them
12:42
<Ahmuck_>
i assume that this is because of "fake net"?
12:42
<johnny>
huh?
12:42
<Ahmuck_>
k, nm
12:43
<sebas891>
johnny: is it possible to configure the "name" variable ?
12:43
<johnny>
name?
12:44
you mean instead of ltspnum?
12:44
you want yournamenum ?
12:44
<sebas891>
"ltsp"
12:44
brb
12:44
<johnny>
nope
12:44
it's hardcoded in the init script
12:44
if you want something better, set real hostnames for them at the dns+dhcp level
12:44
which you should be doing anyways
12:45
if you have the kind of organizaiton that needs ocsinventory
12:45
same for you Ahmuck_
12:45
do it the right way please :)
12:48
<sebas891>
of course :)
12:50
but when you've a large amount of clients, it's a pain the set a hostname for each of them.
12:50
in the dhcp server.
12:50
maybe, I'm missing an option to build automatic hostname for clients.
12:51
<johnny>
no.. that's the point.. it's easy :)
12:51
a file with mac/hostname pairs is all you really need
12:51
and you can build that from ocsinventory i guess :) lol
12:52
<Ahmuck_>
parse the mac address from a file and then auto set hostnames to them
12:52
i suppose
12:52
<johnny>
or make it so they have a firstrun option
12:52
ah.. i guess i can't see how to do that :(
12:53
the fedora one does client-firstoctect
12:53
i stole it for gentoo ltsp before ubuntu had it
12:53
err sorry.. last octect
12:55
<sebas891>
there must be something at the dhcp level, to build automatic hostname like (pc-<ip>) or something else.
12:56
what is the "last octects" ?
12:56
<Ahmuck_>
pc1-mac address, pc2-mac address, etc.
12:56
angryip :)
12:57
<sebas891>
the complete mac address? something shorter?
12:57
<johnny>
last ip octect
12:57
sebas891, you can do something like that with dnsmasq..
12:57
and potentially dhcp.. if it lets you run scripts
12:58
another option tho.. would be another lts.conf var to pass a path to a script that will build the hostname
12:59
<sebas891>
that seems to be a problem outside the ltsp scope, somehow.
13:00
<johnny>
i'd suggest you look at the dhcp man page or search for dhcp build hostname script or somethin
13:00
<sebas891>
when, I do network install with preseed, if I didn't configure the hostname in the dhcp server, the installation fails.
13:01
that is a good thing * i think.
13:01
i'll look at the dnsmasq and the man page of the dhcpd.
13:02
<cyberorg>
sebas891, fedora and suse uses hosts-update script to create /etc/hosts on the client
