I have installed an ubuntu ltsp server in my school.
07:40
<elias_a>
I second that.
07:40
Good for you!
07:41
<peejee>
Most of the pc's work without problems
07:41
<elias_a>
Now I am listening!
07:41
<peejee>
but there is one kind that doesn't
07:41
they always block right after we login
07:41
<elias_a>
Brand, type number?
07:41
<peejee>
compaq evo 510
07:42
I made an lts.conf file
07:42
with the mac addresses of these pc's
07:43
and placed as XSERVER ="vesa"

Have you disabled Compiz?
07:43
http://ubuntuforums.org/archive/index.php/t-1091543.html
07:43
Let me see !compiz
07:43
<peejee>
I did not enable compiz at all
07:43
<elias_a>
No - I cannot do that :)
07:44
Do those machines run on local linux installation?

07:45
<peejee>
they al work as ltsp-client
07:45
nothing is local installed
07:47
<elias_a>
No, I meant are you able to get one of those work 100% if you install the same distribution on HDD in that machine?
07:47
<peejee>
Compiz was installed, I did uninstall now
07:47
<elias_a>
Ok .
07:47
That should get rid of most probs :)
07:47
<peejee>
When I reboot now it should work? or do I have to rebuild my ltsp-image
07:48
<elias_a>
Don't remember to be honest. Rebuild & boot.

It's weird, I even hear the sound when logging in, but the cursor freeses before I get the desktop
07:56
<biomorph_>
Hi All. I've just set up an LTSP server and when I try to log on I get the error message Failed password for invalid user ltsp from 192.168.0.23 port 51536 ssh in auth.log on the server.
07:56
Any idea what I've done wrong?
07:57
Is it worth updating ssh keys?
07:57
<peejee>
updating the ssh key's was the solution for my setup a few days ago.
07:58
<pmatulis>
biomorph_: did you change your IP address recently?

07:59
<pmatulis>
biomorph_: strange
07:59
biomorph_: i would update the client image. i know it seems weird but it has helped me in the past with this kind of problem
08:00
<biomorph_>
I've just run update-sshkeys, update-kernels and update-image.
08:00
<pmatulis>
biomorph_: and still have the problem?

pmatulis: Thanks for your help. Can't explain what was happening. We are just testing the suitability of client machine and they seem to be working OK with one user name.
08:44
Really good clients, no fan, no hard disk so really low power utilisation.
08:47
<pmatulis>
biomorph_: nice. but you're using one common username for all clients?
08:48
<biomorph_>
pmatulis: No - I just set up the server to test. We know all the users work on the production server.

anyone know how i can check cups_server took from lts.conf on a booted client
11:49
or does that only apply to localapps anyway?
11:52Gadi has joined #ltsp
11:58litercola has joined #ltsp
11:59
<litercola>
Just curious what the difference in performance of an ltsp server is using 1 nic instead of 2?
11:59
Is it significant?
12:01alkisg has joined #ltsp
12:02jhutchins_lt has quit IRC
12:05
<alkisg>
litercola: depending on the hardware (nics, pci-e bus...), the wiring & the configuration (just for internet or for bonding etc) it can vary from totally insignificant to doubling the network speed.
12:06
For the typical setup, 1 nic for ltsp clients and 1 for internet, it usually doesn't make any difference in speed at all
12:07
(unless your internet connection is more than 1% of the lan speed :))
12:07
<litercola>
I have 2 gig nics in the server, gig switches, but the clients only have 100m cards, should i upgrade them?
12:08
<alkisg>
You should definitely disable flow control, that gives you 10 times the speed: https://help.ubuntu.com/community/UbuntuLTSP/FlowControl
12:08
How many clients, and how many switches?
12:09
(and those 2 gig nics on the server, are they pci-e or plain pci?)
12:10
<litercola>
pcie on the server, trafic goes through 2 switches at the most, 10 clients is all I will ever need, I think now I have 8
12:10
<alkisg>
8 clients x 100 mbps == at most 800 mbps
12:10
One nic is more than enough
12:10
But you definitely need to disable flow control, if your switch doesn't come with it disabled
12:11
Otherwise you'll get at most 100 mbps, even if the server is gig.
12:11
<litercola>
good deal, with that example, you explained how I should be looking at this, I will check on the switches and look into disabling flow control
12:11
<alkisg>
Of course if your switches are gigabit, then the easiest way is to put gig nics on the clients
12:12
With the best setup, you can get 2000 mbps out of the server
12:12
<litercola>
right, thats what I figured too
12:12
<alkisg>
So, either 100mbps with flow control = on, 800 mbps with flow control = off, or 2000 with some clever nic/switch setup + client nic upgrade

a few days ago i was pointed to gPXE as a way to make some new thin clients boot (or to test them anyway). I'm hoping someone here knows which output format I'm looking for on that page (http://rom-o-matic.net/gpxe/gpxe-git/gpxe.git/contrib/rom-o-matic/)

usb
14:54
<alkisg>
OK, then download the usb keychain image
14:54
Leave the rest options as they are by default

alkisg, add mention of spurious block size options
15:12
people often think they are errors when they are just fine
15:12
<alkisg>
johnny: where? on the client? or on daemon.log?
15:12
<johnny>
daemon
15:13
<alkisg>
Ah, didn't mention that at all, so I guess it's ok :P
15:13
:D do add it please, I didn't see those messages...
15:13
<johnny>
no.. i mean some users see it with different hardware
15:13
i haven't seen it since replacing with newer hardware
15:13
i forget teh exact text
15:14
someting like tftp doesn't support options X
15:14
<alkisg>
Client does not accept options?

Hello, I am trying to do the same thing as in this post http://webcache.googleusercontent.com/search?q=cache:oyWKbYy1H3IJ:www.opensource-archive.org/showthread.php%3Fp%3D216976+ltsp+firefox+association&cd=7&hl=en&ct=clnk . The guy could not use ltsp-remoteapps. I have the same problem. Has anyone an idea how to make it work ?
15:59dlezcano has joined #ltsp
16:05
<alkisg>
poff: an easy way is to make a /usr/bin/evince script on the chroot, which calls ltsp-remoteapps $0 $@
16:10
<poff>
Alkisg : thanks for the tip. What I'like to know is if ltsp-remoteapps script is supposed to work or is it really buggy. I've tried to launch several applications with it . No success.
16:11
<alkisg>
It should. Are you on Lucid?
16:11
<poff>
Yes. Lucid
16:11

!localxterm
16:11
<ltspbot>
alkisg: "localxterm" :: while sitting on a thin client, open a gnome terminal. In that, run: ltsp-localapps xterm. An xterm will open. That xterm runs locally, so any commands you enter there are executed directly on the client.
16:11
<alkisg>
Get a localxterm, and try `ltsp-remoteapps xterm` from there
16:13
<poff>
ltsp-remoteapps xterm does not work. Nothing appears
16:13
<vagrantc>
doesn't remoteapps have to be explicitly enabled?
16:13
in lts.conf
16:14
<poff>
vagrantc: How do you enablee remoteapps in lts.conf ?
16:15* alkisg doesn't use localapps at all, so he doesn't know all the details :)
16:15
<alkisg>
REMOTE_APPS=true
16:21
<poff>
alkisg,ltspbot,vagrantc: It works with REMOTE_APPS=true. Thank a lot !!!

Hi guys, I'm setting up a new LTSP server for a school, and the DHCP server is giving me trouble.
21:20
"No subnet declaration for eth0 (10.60.1.10)." Buuuut... I have "subnet 10.60.1.0 netmask 255.255.255.0 { ..." in /etc/dhcp3/dhcpd.conf
21:21
Has to be something simple I overlooked after configuring several services.
21:24
<vagrantc>
ubuntu?
21:24M4gic5t0rM has quit IRC
21:24
<vagrantc>
is there /etc/ltsp/dhcpd.conf ?
21:24
<PMantis>
vagrantc, Yes.
21:24
<vagrantc>
think ubuntu defaults to that instead of /etc/dhcp3/dhcpd.conf
21:24
<PMantis>
Hmm
21:24
D'oh
21:24
<vagrantc>
if it's present
21:24
check /etc/init.d/*dhcp*
21:25
<PMantis>
That's it... a stupid /etc/ltsp/dhcpd.conf
21:25
and... it started.
21:25
Thanks!

I was without internet for over a year though

I moved to Jamaica btw
22:32

Yeah, ~2 miles south of hedonism
22:35
<mistik1>
ugh!
22:35
<PMantis>
I forget the name of the place, but it was condos.
22:35
LOL
22:35
<mistik1>
that place needs some flame
22:35
<PMantis>
Then, of course, south of that is Rick's Cafe... that place is cool
22:35
<mistik1>
So how's business
22:36
<PMantis>
Tapered off a bit this year. :( Still working with jammcq's client in Rochester, but not as much. Working on picking up more business to fill int eh gaps.
22:37
Typo... oh well

I'll have to look you up if we get a chance to go to Jamaica again... that'd be cool.
22:40
<mistik1>
Sure thing
22:40
just head for Moneague and ask how to get to RiverHead when you do :)
22:41
<PMantis>
Well, I look like a tourist, and I don't know my way around... heard some horror stories about locals being jerks and purposefully giving wrong directions. I think I'd get a GPS receiver. :)
22:42
You on Facebook?
22:42
<mistik1>
nope
22:42* mistik1 dont do the anti-social networking scene

We could kill a goat and some chickens to celebrate :)
