<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?

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?

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

<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
19:27khildin 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.
