| 00:30 | <howard_> Hi I tried to set up an LTSP network on ubuntu 14.04 server. Installed ltsp-server-standalone and openssh-server ok. Install client image ok. Internet on 1 NIC and a few thin clients set to PXE boot on the other NIC but just won't boot :(
| |
| 00:30 | any suggestions?

| 00:48 | <vagrantc> howard_: amd64 server, i386 clients?
| |
| 00:49 | howard_: do the failing try to network boot and fail, or do they not even try to network boot?
| |
| 00:49 | howard_: any DHCP logs of the clients attempting to boot?

| 04:42 | <maldridge> I'm getting this error on ubuntu 14.04, suggestions? cp: cannot stat ‘/tmp/tmp.CSL3j4hxco/boot/.’: No such file or directory
| |
| 04:53 | <vagrantc> maldridge: using ltsp-pnp with a separate boot partition?
| |
| 04:53 | on a server with a separate boot partition...
| |
| 05:04 | <maldridge> no, using the regular chroot method
| |
| 05:07 | <vagrantc> this is during ltsp-update-image ? what is the exact command you're running?
| |
| 05:09 | <maldridge> ltsp-build-client
| |
| 05:09 | I suppose I should specify arch explicitly
| |
| 05:11 | <vagrantc> sounds like it's running "ltsp-update-image --cleanup /" rather than "ltsp-update-image"
| |
| 05:12 | or ltsp-update-image /opt/ltsp/i386
| |
| 05:12 | maldridge: are there multiple images in /opt/ltsp/images ?
| |
| 05:12 | maldridge: are you building i386 on an amd64 server?
| |
| 05:14 | <maldridge> the second one
| |
| 05:14 | and no, I don't think so
| |
| 05:15 | uhh, alarms going off here, I'll deal with this issue later

| 19:21 | <m3741> hey again everyone. how are client video drivers handled? do i need the correct drivers (intel im my case) to be installed and the modules loaded in order to be used by the clients?
| |
| 19:22 | sorry, installed and loaded on the server
| |
| 19:22 | <vagrantc> no, hardware happens on the thin client
| |
| 19:22 | intel drivers will almost surely be installed by default
| |
| 19:23 | anything that requires intensive graphics is likely not well suited to thin clients, though ...
| |
| 19:23 | even youtube videos and such ...
| |
| 19:24 | <m3741> hmm, ok. i'm just having performance problems with firefox. not watching video but say opening three or four tabs to like slashdot, xda-developers, wikipedia, etc. causes a significant amount of lag
| |
| 19:25 | <vagrantc> not terribly surprising
| |
| 19:26 | <alkisg> What are the client specs? cpu/ram?
| |
| 19:26 | <m3741> nothing groundbreaking. some dual core intel atom with 1GB ram
| |
| 19:27 | <vagrantc> sounds like a perfect use-case for fat clients
| |
| 19:27 | <alkisg> You can use it as a fat client if you prefer, yup
| |
| 19:27 | <m3741> hmm, really?
| |
| 19:27 | <alkisg> (ltsp fat client, still diskless)
| |
| 19:27 | <m3741> i figured they'd be a little weak
| |
| 19:27 | maybe i'll give that a shot
| |
| 19:27 | khildin has joined IRC (khildin!~robb_nl@ip-213-49-84-59.dsl.scarlet.be) | |
| 19:27 | <vagrantc> they'll run faster for sure
| |
| 19:28 | <m3741> alright. i'll take that for a spin.
| |
| 19:28 | <alkisg> Check their cpu score on cpubenchmark.net
| |
| 19:29 | From 400 and up they're usually better off as fat clients, from 1000 and up they're satisfactory, newly bought ones should be from 2000 and up
| |
| 19:29 | <m3741> i've pushed them before. they pretty much were fat clients that pulled down a whole image before i set up ltsp. figured the thin client route might have better performance
| |
| 19:31 | i had some homegrown solution using debian's live-build
| |
| 19:31 | thx again
| |
| 19:33 | <vagrantc> as thn clients, they basically are pushing the entire screen over the network constantly...
| |
| 19:33 | which, has some downsides
| |
| 19:33 | LTSP fatclients will probably be comprable to the debian-live setup you had performance-wise
| |
| 19:34 | depending on how it was configured ... might boot a little faster (if you really were loading the whole OS, not just the parts that were used).
| |
| 19:35 | <m3741> makes sense.
