I've got a kiosk setup with a couple of clients. Is there a way to set different startpages in different clients without having a complete installation for each?

I've got a kiosk setup with a couple of clients. Is there a way to set different startpages in different clients without having a complete installation for each?
04:28
<alkisg>
Normal kiosk == with firefox running locally?
04:29
<lenne_dk>
I think so :-)
04:29
I've found where the startup page is set.
04:29
<alkisg>
Where?
04:30
<lenne_dk>
Temporarily forgot... I'll look for it.
04:30
<alkisg>
Do you have a web server running on your ltsp server?
04:31
<lenne_dk>
I do
04:32
Hmm. I must give each kiosk a fixed ip in dhcp.
04:32
<alkisg>
Then the easiest course would be to point the clients to a web page on your server, and to redirect them based on their IP
04:32
<lenne_dk>
Yeah, I just got the same idea :-)
04:32
<alkisg>
(php redirect)
04:33
It's also possible to put an RC script on the chroot and change the startup page as the clients boot, but I think the first idea is easier.
04:35
<lenne_dk>
DHCP and webserver is the same machine. Perhaps a lookup from IP to mac would avoid having go give fixed dhcp-adresses. Hmm wonder if possible from php.
04:38
Anuway, startpage is in /opt/ltsp/i386/usr/share/*/browserconfig.properties
04:38
browser.startup.homepage=http://myhomepage
04:38
browser.startup.homepage_reset=http://myhomepage
04:40
As this only a convenience-factor, not a security-factor, I could make the enduser change the startup page via another php-script.

on debian lenny (ltsp-backports) we seem to be unable to mount local cdroms, usb sticks work fine. on the client i am able to mount the cdrom and read the contents fine, but it does not appear in /media on the server. i have read the LTSPManual.pdf, and the Ubuntu DebugLocalDev page and i cannot see anything wrong. any advice?
07:46
lts.conf has LOCALDEV=True, user is in fuse grop, ltspfs is installed
07:50
hmm, may be related to sata cdroms

hey guys, i have a weird issue when users log out and leave their terms on but shut their monitors off, they come back in the morning and turn the monitor on and the resolution is way scaled down, like 800x600. then they log in and its still wrong, have to log out and back in or reboot
09:37
one says when he logs in like that it actually gives him a res error and reboots itself

denisesball: if you don't find a solution, you could add a shutdown crontab task to ensure that all machines are switched off at night - might save some electricity at the same time - https://help.ubuntu.com/community/UbuntuLTSP/AutomatedTCShutodwn

still struggling with my issue from earlier - on debian lenny (ltsp-backports) we are unable to mount local cdroms but usb sticks work fine. on client i am able to manually mount the cd and i am able to use ltspfsmounter to create icons over ssh. but the drive does not automount into /var/run/drives. if i reboot with the cd in the drive, it is mounted into /var/run/drives, and the icons are there when you login. Only issue then is that you ...
09:52
... cannot eject the cd. Anyone recognise this issue?
09:54
<denisesball>
chrisjrob: i was thinking about that. i dont know if its an issue that can be fixed, i think its just a CRT thing
09:56
<chrisjrob>
maybe if they wait for the login page to reload before switching off their monitor?
09:56
<denisesball>
that is an excellent point
09:56
i wonder if they are or not
09:57
<chrisjrob>
maybe xorg cannot read from a switched off crt monitor - no idea tbh
09:57
<denisesball>
is it possible to force just the LDM resolution?
10:00
<chrisjrob>
pretty sure there is, see https://sourceforge.net/projects/ltsp/files/Docs-Admin-Guide/LTSPManual.pdf/download
10:00
<denisesball>
im reading it now, i dont see a setting just for ldm
10:00
<chrisjrob>
seems there is a shutdown command as well, which i never knew about
10:00
why do you want to do it just for ldm?
10:01
<denisesball>
well i was thinking i would just force ldm but i guess it wouldnt matter since it doesnt detect again until you logout or reboot
10:03
<chrisjrob>
well if you're going to force a resolution, it might as well be the one that you want for all, but i can't say it is a solution that appeals to me
10:03
i.e. you switch off the auto-detection
10:03
<denisesball>
yeah i dont really want to force resolutions on anyone, i just want to avoid this issue
10:03
i think the turning the monitor off before the login screen might be the reason, i talked to the tech and hes gonna make sure he waits tonight
10:03Da-Geek has quit IRC
10:06
<alkisg>
denisesball: if all the monitors have the same resolution, you could force the resolution by specifying X_HORZSYNC and X_VERTREFRESH in lts.conf
10:06
<denisesball>
yeah i'd rather not though
10:07
<alkisg>
OK, but if you have old crt monitors which do not send EDID when they're shut off, you don't have much options, other than telling the users that the monitors must be on to get the correct resolution.
10:09
<denisesball>
i'm just curious how they are working on the old debian 4 server without the issue. i dont think it used edid at all actually
10:10
<chrisjrob>
i do think that shutting them down is the right thing to do
10:11
<denisesball>
yeah ive been looking into that to save power as well
10:11
<chrisjrob>
i like the look of that new shutdown command in lts.conf
10:11
<denisesball>
they'll bitch about waiting for them to boot when they come in, but i can at least get their managers to back me up
10:12
chrisjrob: oooo that is cool. does that mean the wiki process isnt necessary anymore?
10:12
<chrisjrob>
looks like it, if i read that LTSPManual.pdf correctly, it was news to me
10:12
<denisesball>
yeah theres no mention of it besides the command definition
10:12
alkisg: you heard of that one? SHUTDOWN_TIME string, format hh:mm:ss in 24 hour format, default unset

10:26
fi
10:26
Yup, I believe that it should work without doing the stuff that's in the wiki. Never tried it though, I got cron disabled to save memory.

alkisg: where did you look that up, i'd be interested to see if it's also supported in debian?
10:41
<alkisg>
chrisjrob: that's in /opt/ltsp/i386/usr/share/ltsp/ltsp-init-common
10:41
<chrisjrob>
thanks
10:41
<alkisg>
Upstream code is common, so if it's not there on squeze, it'll be on sid etc
10:42
<chrisjrob>
seemingly not there
10:43
nevermind, i'm sure it'll filter down soon enough and anyway, i've implemented it via the wiki method
10:43
<vagrantc>
what are you looking for?
10:43
<chrisjrob>
the lts.conf option for SHUTDOWN_TIME
10:44
it's mentioned in LTSPManual.pdf, i hadn't heard of it before
10:45
<vagrantc>
should definitely be in debian squeeze/testing
10:45
not in debian lenny/stable
10:45
or lenny-backports on backports.org
10:45thunsucker has quit IRC
10:45
<vagrantc>
should be in lenny-backports, that is
10:46
<chrisjrob>
oh, that's what i'm using, i thought...
10:46
5.2.2-1~bpo50+1
10:46
<vagrantc>
ltsp-info
10:46
should display the versions in the chroot and such
10:46
<chrisjrob>
excellent
10:47
<vagrantc>
it won't install lenny-backports into the chroot unless you told it to
10:47
<chrisjrob>
client is at 5.1.90-1
10:48
<vagrantc>
looks like it's from squeeze
10:48
but an old version
10:49
http://wiki.debian.org/LTSP/Howto/Lenny-With-Backports
10:49
<chrisjrob>
my sources.list in the chroot are right
10:49
lenny + deb http://pkg-ltsp.alioth.debian.org/debian lenny-backports mai
10:49
<vagrantc>
ah.
10:49
that's old
10:49
<chrisjrob>
oh
10:50
<vagrantc>
newer packages are now at backports.org

see the URL i posted
10:50
<chrisjrob>
maybe that is also the problem i've just posted to the ml
10:50
<vagrantc>
i should probably kill the old stuff
10:50
i should probably kill the old ones... so people don't keep using it
10:51
<chrisjrob>
indeed
10:51
and i thought i was doing the right thing :(
10:52
<vagrantc>
it *was* the right thing ... about 5 months ago
10:53
<chrisjrob>
i'm SO last season
10:53
<vagrantc>
heh
10:53
<chrisjrob>
hmm, nothing newer coming down
10:53
<vagrantc>
if it's not too much hassle, might be best to rebuild your chroot with the new instructions.
10:54artista_frustrad has quit IRC
10:57
<chrisjrob>
well i have told it to install from lenny-backports and it is bringing down newer packages, so we'll see how i get on
10:57

Hey, i have a question about installing the i386 vs x86-64 on my ltsp server. So i have to use the 32bit version, if i am using 32 bit client pcs?
16:59
<alkisg>
No, you can use the 64bit version and then create a 32bit chroot with `ltsp-build-client -a i386`
17:03
<Yobi>
ok, thank you for the help. i was originally running an i686 server, but i386 and x86_64 would not load.
17:04
is there a way to build x86_64 client on an i686 server?
17:06
and will the clients auto select the version they need, or will all clients run the i386 version?
17:13Lns has quit IRC
17:15
<Yobi>
is anyone there?
17:15
here*
17:17
<Appiah>
well
17:18
ltsp-build-client --arch=x86_64
17:18
<Yobi>
i'm assuming i686 should run on all p2-4 clients, so u should just run ltsp-build-client -a i686
17:19
i c
17:19
<Appiah>
or maybe there isnt a = between
17:19
just try or check manual
17:19
<Yobi>
ok. i'll check. thanks both of you. i'll shut up now ;)

Anyone using Ubuntu 10.04 with LTSP?
17:25
I'm having an issue with LDM on a brand new install, basically all you see is a splash screen, you can click around and eventually get something to show up...any ideas?
17:26
<alkisg>
Yobi, sorry I wasn't looking at the channel. ltsp-build-client --extra-help shows a lot of stuff there, --arch amd64 might be what you want.
17:27
cgrossko: you mean the plymouth splash screen? Or ldm, the login screen where you enter your username/password?
17:27
<cgrossko>
LDM login screen
17:27
the username/password box are missing as well as the Preferences button in the bottom left hand corner
17:27
<alkisg>
Ah. Did you install some weird ldm version? E.g. self-compiled?
17:28
<cgrossko>
no, this is a fresh install also
17:28
<alkisg>
And what do you mean with "and eventually get something to show up" ?
17:28
Do you see something eventually, or just the ldm background?
17:29
<cgrossko>
basically I can click where I know the preferences button is (I cannot see I just click around) and then preferences show up, as well as the login box (with no text around it).
17:29
<alkisg>
How much RAM does your client have?
17:29
<cgrossko>
1 gig
17:30
<alkisg>
Hmmm that's weird. Can you try putting XSERVER=vesa in lts.conf?
17:30
<cgrossko>
sure
17:32Ynnek has joined #ltsp

hi all ;-)
17:34
I have a problem with a 3com card (no ISA)... The pxe load perfect, but DHCP not assign an IP.
17:34
<cgrossko>
After reboot I don't get the LDM screen just process:231): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0)
17:35
<alkisg>
cgrossko: what graphics card is that on the client?
17:35
<cgrossko>
not sure its an HP T5735
17:36
<alkisg>
Can you remove the xserver=vesa line and try with another client, to make sure it's a client problem?
17:36
(and not a bad chroot etc)
17:36
Ynnek: distro/version?
17:37
<cgrossko>
I tried CONFIGURE_X=True and it seems to be coming up now. It's weird it worked fine the first boot though
17:37
<alkisg>
CONFIGURE_X shouldn't do anything on 10.04
17:37
It's automatically set to true appropriately
17:37
<Ynnek>
alkisg: ¿how are you?
17:37
<alkisg>
I'm fine, thank you
17:37
<Ynnek>
alkisg: ubuntu 8.04
17:38
<cgrossko>
alkisg, your right, this time it booted goofy again
17:39
<Yobi>
i can see you're busy but i got 1 more question. i ran the i386 build, but the client is still trying to boot x86_64. should i purge chroot or something to remove the x86_64, and rebuild the i386
17:39
<alkisg>
Yobi: no, you need to change your dhcpd.conf
17:39
Don't worry about asking questions, go ahead
17:40
Ynnek: can you try putting this new line at the end of /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default ?
17:40
ipappend 3
17:40
(in a new line)
17:40
Reboot the client and see if it boots.
17:40
<Ynnek>
alkisg: just ipappend 3
17:40
?
17:40
<alkisg>
Yes, it'll bypass dhcp completely (temporarily)
17:42
<Ynnek>
alkisg: Ok...
17:42
let me try
17:43
idem
17:45
<alkisg>
So it isn't a dhcp problem
17:45
Maybe it's a module problem. Did that ever work? Does it work if you e.g. boot it with a live cd or usb or something?
17:46
<Ynnek>
alkisg: No, in fact, i have others thin clients (whit other cards) and working fine.
17:47
<alkisg>
So maybe the module is missing for that card. You'd need to find out the correct module for that card and insert it to the chroot kernel.
17:47
<Ynnek>
alkisg: Well, i can try with a floppy linux live...

I've no idea about ati, but do try adding "nomodeset" as a kernel parameter in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default (right next to quiet splash)

last question. the P3-P2 systems i have are just gonna be kiosk type systems for firefox. do i need to create seperate users for each of them, or can they all log 1 profile at the same time
18:04
<alkisg>
Yobi: which distro/version?
18:07
<Yobi>
um 10.04
18:07
i did the quick install from the 64bit alternative cd
18:10
<alkisg>
No you don't need to create a user
18:10
Kiosk "users" are automatically created on boot
18:11
<Yobi>
so how do i log in as a Kiosk user?
18:12
nevermind. i figured it out

alkisg: I tested the network card with a small linux distribution and it's work.
18:29
<alkisg>
Ok, what module is it using?
18:29
<Ynnek>

18:30
3c59x
18:31
is a 3Com 3c905B Cyclone

mkdir /tmp/initrd
18:32
cd /tmp/initd
18:32
*cd /tmp/initrd
18:32
cp /var/lib/tftpboot/ltsp/i386/initrd.img .
18:32
gunzip -c initrd.img | cpio -i -d -H newc --no-absolute-filenames
18:32
find . -name 3c59x.ko
18:32
Is it there?
18:33
<Ynnek>

./lib/modules/2.6.24-16-generic/kernel/drivers/net/3c59x.ko
18:36
<alkisg>
OK, so the module is there. I don't know what the problem might be then.
18:36
<Ynnek>
alkisg: yes, is crazy.
18:38
<Yobi>
is there a small version of linux that i might be able to use to log into the LTSP server? similar to RDP connections on Windows?
18:38
i think i saw ltsp client in a repository somewhere... just dont remember
18:39
<alkisg>
You mean over WAN?
18:39
I.e. why don't you just boot from the ltsp server?

a couple of the systems dont have a pxe option in the bios. so i was wondering if there was a work around...
18:41
<alkisg>
You can use gpxe for that
18:42staffencasa has quit IRC
18:42
<alkisg>
And boot either from a cd, a floppy, a usb stick, or a hard disk
18:42
!gpxe
18:42
<ltspbot>
alkisg: "gpxe" :: the successor to etherboot (http://etherboot.org). To download bootable floppy, cd, usb, kernel etc images, visit http://rom-o-matic.net/

<Yobi>
thanks for the help once again... you saved me a lot of research time. i stayed here about 2 hours longer than expected, so i'll test that out tomorrow, lol
