| 00:24 | <sweetpi> can anyone tell me where the script that sets certain conf files as tmpfs is located?
| |
| 00:25 | alkisg has joined #ltsp | |
| 00:25 | <vagrantc> sweetpi: which distro?
| |
| 00:26 | and version and such
| |
| 00:26 | <sweetpi> debian squeeze
| |
| 00:27 | ltsp 5.2.2
| |
| 00:27 | <vagrantc> it's called ltsp-bindmounts
| |
| 00:27 | it's in the chroot ... either usr/bin or usr/sbin, i think ...
| |
| 00:27 | you can override the defaults with lts.conf variables
| |
| 00:27 | oh, it might be in usr/share/ltsp
| |
| 00:28 | <sweetpi> there it is, thanks
| |
| 00:28 | <vagrantc> in usr/share/ltsp ?
| |
| 00:29 | <sweetpi> hmm i can override.. nice, that in the docs?
| |
| 00:29 | yes
| |
| 00:29 | <vagrantc> i don't think it's in the docs very well ... it's a pretty new thing
| |
| 00:29 | * vagrantc isn't always the best at keeping up with docs | |
| 00:30 | <sweetpi> ok, how would i override copy_dirs or bindfiles?
| |
| 00:30 | rather append actually
| |
| 00:30 | <vagrantc> append is something i've really been meaning to add ...
| |
| 00:31 | in lts.conf, LTSP_COPY_DIRS="/root /home ... /your/extra/dirs"
| |
| 00:31 | <sweetpi> im trying to get wireless to come back up if it drops.. so im thinking adding the wpa conf might help
| |
| 00:32 | <vagrantc> oh, adventurous
| |
| 00:32 | <sweetpi> ok, so i need to set the defaults in there and then add mine?
| |
| 00:32 | <vagrantc> yeah
| |
| 00:33 | <sweetpi> thanks
| |
| 00:33 | oh.. i guess i need bindfiles.. not copydirs
| |
| 00:33 | LTSP_BINDFILES?
| |
| 00:37 | <vagrantc> yup
| |
| 00:38 | leio_ has quit IRC | |
| 00:38 | <sweetpi> hmm does that need to be in the initrd?
| |
| 00:39 | <vagrantc> the way i implemented it... no :)
| |
| 00:40 | it's a little crazy, but it runs from the initramfs, but while the root filesystem is mounted, so it runs it chrooted to the root filesystem :)
| |
| 00:40 | <sweetpi> nice
| |
| 00:41 | <vagrantc> so i have access to more complicated tools than are available in the initramfs, but still happens before init even runs.
| |
| 00:41 | used to run from the init script, but that was hard to ensure that it ran early enough.
| |
| 00:42 | <sweetpi> that worked good, now to figure out what i need to mount for the network to come back up... bleh
| |
| 00:43 | alkisg has quit IRC | |
| 00:46 | <sweetpi> im glad you didnt put those in the initrd, im getting tired of copying new initrd's for one conf chage :)
| |
| 00:46 | s/chage/change/
| |
| 00:57 | <vagrantc> indeed. i didn't like the idea either.
| |
| 00:57 | actually, i largely did it to avoid having to implement lts.conf handling in the initramfs :)
| |
| 00:57 | because clearly the configuration should be in lts.conf
| |
| 00:58 | <sweetpi> you dont happen to know what would need to be in tempfs to be able to bring an interface up do you?
| |
| 00:58 | <vagrantc> but i didn't like the idea of regenerating the initramfs if you don't have to...
| |
| 00:58 | sweetpi: using ifup/ifdown ?
| |
| 00:59 | <sweetpi> i guess, right now im just testing yanking the card and plugging it back in
| |
| 00:59 | yeah, since ive added wireless support i seem to be updating the initrd every other change ha
| |
| 01:02 | oh.. pcmcia btw.. "yanking" the card might have sounded odd if you thought i was on a desktop :)

| 05:10 | <zeitsofa> hello :) - i was setting up a ltsp server and i thin client can boot. but i try to login as a user the error occured no answer from server - restart
| |
| 05:11 | <alkisg> zeitsofa: is that ubuntu?
| |
| 05:11 | <zeitsofa> alkisg: it is, yes.
| |
| 05:11 | <alkisg> Try: sudo ltsp-update-sshkeys && sudo ltsp-update-image
| |
| 05:13 | <zeitsofa> ah ok i didn#t create teh user on ltsp server. now i can login but there is a CLI - can i have a gui,too?
| |
| 05:17 | <alkisg> Do you have a desktop environment installed on the server?
| |
| 05:21 | <zeitsofa> i think i need a lts.conf for the clients. first i will create one
| |
| 05:25 | <ogra> you dont need an lts.conf
| |
| 05:25 | <zeitsofa> hmm ok but i dont have a running gui on the thin client
| |
| 05:25 | <ogra> if your clients boot but you cant log in, the prob lies on the server side
| |
| 05:26 | you need a desktop environment installed
| |
| 05:26 | it doesnt need to be running, but it needs to be installed
| |
| 05:26 | <alkisg> zeitsofa: did you use the ubuntu server cd to install the system?
| |
| 05:34 | <zeitsofa> alkisg: yes i did
| |
| 05:34 | <alkisg> zeitsofa: then you also need to run "apt-get install ubuntu-desktop"
| |
| 05:35 | zeitsofa: the proposed way to install LTSP is NOT with the server cd. It's with the alternate cd, which contains a GUI.
| |
| 05:35 | <zeitsofa> alkisg: hrhr i did 2 minuts ago
| |
| 05:35 | alkisg: ok but i didn't have a gui the server is headless
| |
| 05:36 | <alkisg> It doesn't matter. LTSP servers need a GUI to serve the clients.
| |
| 05:42 | <zeitsofa> how did you mean "serve the clients"?
| |
| 05:43 | <alkisg> When the clients boot, they need to get the OS and a GUI. They get it from the server. That is called the "client-server" model, where the server serves the clients.
| |
| 05:50 | <zeitsofa> hmm - i have installed ubuntu-destop in the client image not on server, so the server can run headless.
| |
| 05:50 | <ogra> the session after you log in on the client runs on the server, so you need all desktop session related apps installed on the server
| |
| 05:50 | that wont work
| |
| 05:50 | if your clients are beefy enough you could run them in fat client mode though
| |
| 05:51 | just installing ubuntu-desktop in the client env wont gain you anything
| |
| 05:51 | <zeitsofa> hmmm ok.
| |
| 05:54 | so i have to install all programms for clients on the server?
| |
| 06:04 | <alkisg> zeitsofa: yes, unless you follow this how to for fat clients: https://help.ubuntu.com/community/UbuntuLTSP/FatClients
| |
| 06:06 | <zeitsofa> oh nice thx a lot
| |
| 06:06 | <alkisg> zeitsofa: what are your client specs?
| |
| 06:08 | <zeitsofa> atm there is a core i7 with 8GB RAM, but this is only a test client in future there a atom CPUs with 1,2GHz and 2GB RAM, floppy, cdrom, soundcard and usb ports
| |
| 06:08 | <alkisg> OK, they're fine for fat clients.
| |
| 06:09 | <zeitsofa> it is a test project - so i'd like to test the different ways and find a good solution for the end project.
| |
| 06:10 | but my favorite is a small thinclient with atom, because wie have a big 2x 3GHz xeon quadcore with up to 128 GB of ram.
| |
| 06:12 | <alkisg> Atoms with 2GB RAM shouldn't work as thin clients...
| |
| 06:12 | They'll be much faster as fat clients
| |
| 06:18 | <zeitsofa> hmm we only have atom board configurations here.
| |
| 06:28 | <alkisg> So? they're fine.
| |
| 06:32 | <ogra> you can surely use them as thin clients, its just a waste of processing power to do that :)

| 06:37 | <zeitsofa> i think i can find clients for a lower cost flow :D

| 07:22 | <zeitsofa> hmm no i have installed some packages on the server and run "ltsp-build-client && ltsp-update-sshkeys && ltsp-update-image" and boot the client. the client get ip and find bootimage - the ubuntu boot screen comes up but now i have a black screen :/
| |
| 07:23 | on tty[1-6] i have a login promt but not a graphical login comes up. any ideas?
| |
| 07:29 | Faithful has quit IRC | |
| 07:38 | <alkisg> zeitsofa: "some packages" may not be enough. Did you install ubuntu-desktop?
| |
| 07:38 | <zeitsofa> alkisg: yes i did
| |
| 07:39 | <alkisg> What graphics card do the clients have?
| |
| 07:39 | <zeitsofa> on this client there is a via s3
| |
| 07:41 | <alkisg> Try with XSERVER=vesa in lts.conf
| |
| 07:41 | I.e. create a /var/lib/tftpboot/ltsp/i386/lts.conf file, with the following contents:
| |
| 07:41 | [Default]
| |
| 07:41 | XSERVER=vesa
| |
| 07:42 | (or try with a different client)
| |
| 07:42 | <zeitsofa> ah ok. i have disable XSERVER=auto and gui comes up.
| |
| 07:43 | thx a lot :)
| |
| 07:43 | Faithful has joined #ltsp | |
| 07:44 | <zeitsofa> alkisg: with vesa it works fine,too :)
| |
| 07:44 | <alkisg> Don't use vesa if it works without it
| |
| 07:44 | <zeitsofa> on first i try without xserver= line
| |
| 07:48 | alkisg: to use sun-jave6-sdk|jre|plugin i have to install on server right?
| |
| 07:49 | <alkisg> Yes. Usually we just install the ubuntu-restricted-extras package, it has all the usual plugins (flash, java, codecs etc)
| |
| 07:50 | <zeitsofa> really? on ubuntu10.04 sun's java is only in parnter repo available.
| |
| 07:52 | <alkisg> Hmmm they changed it again, it only installs the icedtea6-plugin now... ok
| |
| 07:53 | <zeitsofa> is this the real java from sun?
| |
| 07:53 | because we need the sun java package

| 09:19 | <maslak> hello - i'm testing dual-display under ltsp. my problem is i've got 2 monitors connected to thin client, and i'd like to use rdesktop on anotheer screen (like i used before: screen_5 & screen_6 were rdesktops to different machines, and screen7 - standard ldm) now i'd like to use 7 monitors under my linux enviroment (simply to viev my cctv cameras on one, and work on another)
| |
| 09:20 | main problem is that when i transfer to rdesktop screen - it's wide to 2 monitors and left-right is inverted, config is ok under my X, bun under rdesktop it looks like shit.

| 10:05 | <Grindar> ok guys, I'm running ltsp on a fedora box, with dhcp on a windows server. All that seems to be working fine. The trouble is once the client boots, I attempt a login, and it comes back with "No response from server, restarting"
| |
| 10:05 | any ideas on where the trouble could be?

| 14:14 | <danno> My fatclient setup is standard but I'm not able to apply a Sabayon profile. Sabayon is installed in the chroot. The profile is generated on another machine and them copied over. After a 'ltsp-update-image' I see the profile is copied to the users home directory but it is not effective whenteh user logs in.
