i am having a problem with ltsp server configuration
08:07artista_frustrad has joined #ltsp
08:07
<dimtiris82>
i didnt remember wht i changed when i tried to change the ip address and tried to bridge the physical device with the ltspbr0(emu) device
08:08
and when i tried to run with ltsp-vmclient it tells me that no ip address found
08:08
and suggests?
08:10
also i put the default ipZ on dhcp.conf of ltsp but no access

ciao! how can change bightness (gamma) on my thinclient crt...xgamma don't work :(
12:54greenlion has joined #ltsp
12:54
<sbalneav>
Ummm, push the brighness control on the monitor up or down? :)
12:55
<ogra>
or wait until sbalneav implemented dbus tunneling ;)
12:55
then you can use the brightness applet
12:55
<sbalneav>
Or use ltsp_localapp xgamma ....
12:55
<ogra>
yeah
12:56
<sbalneav>
I like just adjusting the brightness on the monditor :)
12:56
Simple, and works :)
12:56
<ogra>
indeed
12:57
<sbalneav>
You know what I hate? VMWare sees fit to base it's freaking VM platform on linux, but I have to have a WINDOWS box in order to have the management tools needed to actually CREATE a virtual machine.
12:57
this sucks.
12:57
<muttley_>
my crt don't have brightness controll!!
12:57
<ogra>
use kvm :)
12:57
or UEC :)
12:58
<muttley_>
have separeted gamma controll (red green blue)
12:58
<ogra>
muttley_, use ltsp_localapp xgamma then
12:58
as sbalneav said
12:59greenlion has left #ltsp
12:59
<sbalneav>
UEC's what now?
12:59
I *wanted* to use KVM, but I got outvoted :)
12:59
<ogra>
ubuntu enterprise could
12:59
<sbalneav>
vmware's apparently more *enterprisey*
12:59
<ogra>
*cloud
12:59
<muttley_>
ltsp_localapp ?!? this mean install xgamma on thin client (local)
12:59
<sbalneav>
muttley_: yup
13:00
<ogra>
.oO(funny typo though)
13:00
<muttley_>
oooook
13:00
thank you!
13:00
<sbalneav>
It looks like it's part of the "x11-xserver-utils" package
13:00
so it MAY already be there.
13:00
<ogra>
sbalneav, i hope stgraber jumps on it in lucid so we have cloud supported LTSP :)
13:01
<sbalneav>
Lucid what? Llama?
13:01
<ogra>
then it should just become an option on the CD :)
13:01
lynx
13:01
<sbalneav>
Ah
13:01
Lynx isn't an african animal is it? They're here in North America
13:01
<ogra>
[ ] "install LTSP enterprise could cluster" :)
13:01
europe too
13:01
<muttley_>
...and UEC or KVM what is?
13:02
<ogra>
koalas arent african either :)
13:02
<sbalneav>
Well, true
13:02
ok, so it's not african animals only.
13:02
<ogra>
muttley_, KVM is virtualization software ... clouds are scalable virtual machines
13:03
<sbalneav>
I do however, like lynx's. Both the cats, and the web browsers
13:03* ogra too
13:03* ogra needs to go packing now ...
13:03
<sbalneav>
I can't do anything with clouds here at LAM, owing to chain-of-custody concerns.
13:03
<ogra>
pfft
13:04
you can set up a local cloud server
13:04
UEC means you run the cloud in *your* DC
13:04
and just benefit from the endless scalability
13:04
<sbalneav>
Karmic's gonna have all that built in, yes?
13:05
I think I saw SOME kind of large cat-like creature out at my cottage a couple of weeks ago.
13:05
<ogra>
yup
13:05
<sbalneav>
Might have been a lynx
13:05
<ogra>
heh
13:06* ogra has a bunch of racoons in the garden
13:06
<sbalneav>
So far, I've had (at the cottage)
13:06
<muttley_>
i'll try ltsp_localapps :) ...tnx again!
13:07
<ogra>
but i really need to go packing ...
13:07
<sbalneav>
Skunks, black bears, wolves, foxes, great grey owls, deer, racoons, mice, squirrels, hawks, and about 1x10^8 species of birds.
13:07* ogra drives to amsterdam tomorrow ....
13:07muttley_ has quit IRC

Taking Susie?
13:08
<ogra>
nope
13:08
work stuff
13:08
and we have nobody for the animals
13:08
<sbalneav>
I hear there's good beer in Amsterdam :)
13:08
Hoist a pint for me :)
13:08
<ogra>
well, amstel
13:08
<sbalneav>
phht
13:08
<ogra>
will do :)
13:08
<sbalneav>
I'm sure there's better local stuff
13:09
<ogra>
for sure, i'll dig something up to have it for you ...

<kusznir>
Hi all: I'm new to LTSP5 (I had been 'current' back in the 4.2 days), and I'm trying to set up a test Ubuntu server. Unfortunately, all the packages and docs assume a fairly basic setup, which does not match mine, and I can't seem to find enough documentation/files to set it up.
14:28
Basically, I'm trying to run this in an "enterprise network". I have an existing dhcp server, which I can modify the next-server, filename, and option root-path dhcp options. I have another server that does TFTP, but I don't mind if the ubuntu LTSP server does this.
14:29
The LTSP server must NOT run dhcp (that will break the network / piss off way too many people! :) ).
14:30
However, as my LTSP box did not have two nics in it, it appears that the setup scripts kinda broke. I have my /opt/ltsp/i386 directory and image, but I don't have any of the pxelinux / kernel / initramfs stuff. It installed dhcp, but did not configure it so I don't know what the magic is for the root-path option to use the image.
14:30
I also don't know how to verify that whatever is required to serve up the image (is it still NFS?) is actually configured/running.
14:30
<alkisg>
NBD is used now
14:30
OK, let's take this one by one
14:31
"I don't have any of the pxelinux / kernel / initramfs stuff" ==> what do you have in /var/lib/tftpboot/ltsp/i386 ?
14:32
<kusznir>
Ok, its there. I didn't know that's where tftpboot is hidden these days (I've always seen it at /tftpboot or /tftproot)
14:32
<alkisg>
Next one, to remove dhcp3-server:
14:32
sudo apt-get install ltsp-server
14:32
sudo apt-get install ltsp-server
14:32
*yes, do that twice*
14:33
sudo apt-get --yes --auto-remove purge ltsp-server-standalone
14:33
*ok you may omit the --yes :)
14:34
<kusznir>
74.9MB disk space will be freed....wow...
14:34
thanks for the help, btw.
14:34
(my system is still thinking/working)
14:35
btw: Ideally, I think I'd like to run nx as my communication protocol. Is this (easily) supported by current ltsp?
14:35
Ok, got my prompt back.
14:36
<alkisg>
Other people here use nx more than me, I'll leave that question for them :)
14:36
Now, to configure your other server.
14:37
<kusznir>
filename, I assume its something like /ltsp/i386/pxelinux.0, right?
14:37
<alkisg>
Yes, and you also need to point next-server to your ltsp server
14:38
<kusznir>
Yep. What about the option root-path?
14:38
That's the big question for me, as I had always done NFS root, and I don't know how to specify NBD.
14:38
<alkisg>
It isn't needed at all :)
14:39
It's only used in nfs, and ubuntu doesn't use it by default
14:39
<kusznir>
Ok. So it just looks to next-server for that?
14:39
<alkisg>
But I *think* that I've heard about one or two broken pxe clients that do not boot if that's no present, so you may want to put it there just to be safe...
14:40
Yes, next-server is used as the ltsp server
14:40Selveste1 has quit IRC
14:40
<alkisg>
option root-path "/opt/ltsp/i386";
14:40Selveste1 has joined #ltsp
14:41
<kusznir>
Also, with nbd, my lts.conf file won't be editable in the image. I recall in the LTSP docs that this file is tftp-transfered, but I don't see it...
14:41
<alkisg>
You create it in /var/lib/tftpboot/ltsp/i386/lts.conf
14:41
You don't need to update the image to edit the lts.conf anymore
14:43
<kusznir>
ok, thanks. I'll let my dhcp config files update, and try it out!
14:44
<alkisg>
kusznir: I'm a little worried about the 75Mb freed space, though... which packages were removed?
14:45
(I guess they were left overs from some other installation, and autoremove removed them)

<elias_a>
I do not understand what the dudes at Adobe think they are doing...
15:01
<alkisg>
I think flash *never* supported unicode... so it is a big change for them
15:02fotanus has joined #ltsp
15:02
<alkisg>
Really, we were hearing about unicode in delphi since 2004, and it got there in delphi 2009!
15:02
I'm guessing adobe will need a few more years to get this right :(
15:02
<elias_a>
Well - not supporting Unicode is equivalent of being out of business very soon...
15:03
But let's hope for the best.
15:03Guest56707 has left #ltsp
15:03
<alkisg>
Nah, the ads don't need unicode :(
15:03Guest56707 has joined #ltsp
15:03
<alkisg>
...and also the codepages still work in windows
15:04
<elias_a>
On the other hand we have a FLOSS webconferencing tool that handles UTF8 correctly in MacOsX and Linux, too :)
15:04
Adobe does not :)
15:04
<alkisg>
Huh? which one are you talking about?
15:04
<elias_a>
OpenMeetings.
15:05* alkisg really wishes all the flash-loving devs of the internet switched to silverlight... at least moonlight works :-/
15:05* alkisg looks at openmeetings
15:05
<elias_a>
We used the workaround written by the dude running OpenStreetMaps.
15:06
So even given the fact that Flash Player is broken we can make the scandinavian characters & other stuff at least seem to work... :)
15:06
<Guest56707>
the video tag is the future hopefully

<elias_a>
alkisg: Why not?
15:09
<kusznir>
Is it "normal" for the thin client to take a long time to boot (say, 2 min) that could boot ltsp 4.2 in around 30 sec?
15:10fotanus1 has joined #ltsp
15:10
<elias_a>
kusznir: What distro?
15:10
<kusznir>
Ubuntu 9.04
15:10
<elias_a>
Yes it is.
15:10
<alkisg>
elias_a: They're not on the iso-8859-1 codepage... so we see 2 chars for every 1 greek char
15:11
kusznir: you may want to try LDM_DIRECTX=True in lts.conf, which is insecure but faster (read the docs about the security implications)
15:12fotanus has quit IRC
15:15
<elias_a>
alkisg: But that is the situation with the scandinavian characters as well - trying to type ä for example gives certain string of false characters.
15:16
alkisg: Is it something else you mean?
15:16
<kusznir>
elias_a: Are you familar with NX and its use with LTSP?
15:16
<elias_a>
kusznir: I have used it. It works.
15:16
<kusznir>
(asking you based on some comments a bit firster up to zamba)
15:16
<alkisg>
elias_a: http://en.wikipedia.org/wiki/ISO/IEC_8859-1 ==> ä = 00E4
15:17
<kusznir>
Cool...does it usually perform better than ldm?
15:17
<alkisg>
elias_a: but α (the greek one) isn't there on that table
15:17
<kusznir>
Are there down sides to using it?
15:17
<elias_a>
alkisg: Oh right - and they are not supporting any codepage with greek alphabet?
15:18
<alkisg>
Nope, none at all.
15:18
<elias_a>
kusznir: It is like VNC, usable but you notice the latency.
15:18
<alkisg>
Unless of course if I switch my linux to iso-8859-7 and get to a chaos :)
15:18
<elias_a>
alkisg: Shall we go and beat them up? :P
15:18* alkisg gets his club.. :D
15:19
<alkisg>
kusznir: also I think you won't get sound, localdevs etc with nx
15:19
<elias_a>
Hmmm... where's my gun...
15:19
<kusznir>
Oh...ok...I thought NX (at least claims) support for most of that stuff...so I thought it might even be easier.
15:20
<elias_a>
kusznir: Easier than what?
15:20
<kusznir>
I also like the idea of being able to disconnect and reconnect to the session, but perhaps the drawbacks aren't worth it.
15:20
<elias_a>
Oh - that way.
15:20
<kusznir>
According to nomachine's page, nx supports local disk, sound, and printer forwarding "transparently"...I've never tried to get that working before, though, so I don't know how easy it actually was. But they made it sound very easy...
15:21
<elias_a>
NX is OK for example connecting to your office system remotely but you do not want to do it on regular basis.
15:21
I have never tried sound on NX but I doubt that.
15:21
<kusznir>
Ok. I think I'll have to have nx running for remote users, but it sounds like I'm better off with ldm for local client use.
15:21
<elias_a>
I'll ask Asmo Koskinen about it.
15:25
<zamba>
kusznir: you basically just set up nx on the server, yeah?
15:25
<sbalneav>
kusznir: Yes, LTSP5 takes longer to boot, as everything about Linux has gotten bigger since the 4.2 days.
15:28
<elias_a>
sbalneav: And the amount of automagically initialized hardware has exploded
15:32
<johnny>
test
15:37
<sbalneav>
elias_a: yes. All of this increases "boot time"
15:37
The real guage is how it funtions AFTER boot.
