goodmorning guys
08:03
Can someone help me?
08:05
I need a graphical boot instead of the boot messages
08:05
Can someone help me with that?
08:06
<monkwitdafunk>
Are you using a thin client
08:06
<needhelp__>
yes
08:06
Its booting already
08:06
I just want to hide the bootmessages for the users
08:07
Can you help me with that?
08:08
<monkwitdafunk>
Are you using BIOS before the operating system?
08:08
it is tje other option than post messages
08:09
Choose logo screen
08:10
<needhelp__>
what do you mean with
08:10
Are you using BIOS before
08:10
<monkwitdafunk>
Which operating system are you using for the dhcp server to pxe boot?
08:11
<needhelp__>
The thinclient boots up, searches for the pxelinux.cnf and than displays boot messages until its booted
08:11
I want to hide the boolines
08:11
I am using debian 7 wheezy
08:11
*bootlines
08:11
<monkwitdafunk>
Oh. Some hardware may have a mandatory setting if an extra bus is used
08:12
Mandatory post messages if this pci slot is taken by this hardware
08:12
<needhelp__>
Yes
08:12
<monkwitdafunk>
It depends on your manufactured systen
08:13
<needhelp__>
But in ubuntu you can hide that messages by using a splash screen
08:13
Its does not depend on the system
08:13
Its already booting
08:13
I have to change something in the ltsp-client
08:13
<monkwitdafunk>
Post messages cone first
08:14
<needhelp__>
what do you mean with that?
08:15
<monkwitdafunk>
Input and output before the oeprating system and then operating system start
08:15
<needhelp__>
yes I know
08:16
<monkwitdafunk>
Or it can be io over a network to access the os
08:16
<needhelp__>
But there must be a possibility to make a bootsplash for that
08:16
Its using pxe
08:17
so its over the network

Do you know how to configure grub by editing with a text editor
08:19
<needhelp__>
yes
08:20
But pxe is not using grub??
08:20
<monkwitdafunk>
Your better than me then
08:20
<needhelp__>
hmm okay
08:20
<monkwitdafunk>
I have seen the example.of grub used
08:20
<needhelp__>
where are you using ltsp for than?
08:22
<monkwitdafunk>
I am not using it right now but i should try as a hone user
08:22
Home*
08:22
<needhelp__>
ahh okay
08:22
You really should try it
08:22
Its a very nice system
08:22
And its not slow
08:23
<monkwitdafunk>
Maybe i can
08:24
I can use one operating system on a three computers
08:26
<needhelp__>
yes
08:26
But when it runs on 3 it also runs on 20
08:26
Or when you have a more powerfull computer you can run like 500 on them
08:27
I am using this system on a school right now
08:27

08:57
For example, when I install Ubuntu on a server, and make a thin client setup, it -has- a boot splash.
08:57
Where did yours go?
08:57
<work_alkisg>
He's using debian
08:57
<Hyperbyte>
Oh....
08:58
Well, I don't know anything about Debian.
08:58
<work_alkisg>
Yeah I told him it's not an ltsp issue but he won't listen
08:58

work_alkisg: OKAY ! I confirm: USB disks with ext(x )formats, even they arn't internals are considered as internals. everything works now with LOCALDEV_DENY_INTERNAL_DISKS=False

hyperbyte

Its not in use yet
09:14
Can you please help me?
09:17
<Hyperbyte>
needhelp__, okay - so if you're still experimenting... try Ubuntu 12.04 with LTSP. See how that works out vs. Debian. You'll also be able to get -a lot- more support for Ubuntu, since it's what most LTSP users use.

09:19
<needhelp__>
I am doing this for this school
09:19
they asked me to use debian because all of it is debian
09:20
<Hyperbyte>
Right, and your advice to them should be, LTSP is most used with, best supported on and most actively developed for Ubuntu, we should rather choose that.
09:21
If you absolutely -must- use Debian, then you must find someone who also uses Debian to support you.
09:21
<needhelp__>
Yes that would be an option, I first will tryout ubuntu.
09:22
<Hyperbyte>
LTSP is nothing more than a tool that enables any Linux OS to boot thin clients over the network.
09:22
<needhelp__>
Do you know if there is a standard bootsplash in ubuntu?
09:22
<Hyperbyte>
-How- the thin clients boot and -what- desktop experience the clients provides, that's entirely up to the distribution used.
09:22
<needhelp__>
Yes I know that
09:24
<Hyperbyte>
So if you don't see a splash screen with Debian, or if you don't get a nice desktop with Fedora - that's outside of the scope of the LTSP project. You could ask in #debian, maybe someone there knows.
09:24
<needhelp__>
I am already doing that
09:25
No one can tell me....
09:25
But thanks for your support
09:25
<Hyperbyte>
Well, if it's not working out, try another distro. :-) Also tell your IT colleagues that they should always use a distribution that is most suited for the task, not necessarily "always the same" distribution.
09:26
<needhelp__>
Yes okay, I am on a internship :p
09:26
<Hyperbyte>
I'm running CentOS here as host for my virtual servers. My LAMP server is Fedora, my Asterisk server is CentOS and my LTSP server is Ubuntu... why? Because Fedora has newer PHP version than CentOS, and because Ubuntu has much better LTSP support than CentOS. ;-)
09:26
<needhelp__>
But if the ubuntu works better I will tell them
09:26
Where are you from than?
09:27
Which city?
09:27
Which company
09:29
<Hyperbyte>
Rotterdam. I work at a company that provides recreation & care for disabled people. Mainly we organize group vacations for people with a mental disability, who need some guidance & companionship during vacation, but we do other things as well.
09:33

<der_baer>
hi all, is ldm supporting PAM ? I have an ubuntu 12.04 FATclient enviroment and want to unlock the gnome-login keyring, the normal way would be to edit some files under /etc/pam.d/ but that seems not supported. There is a way to feed the gnome-keyring-daemon over STDIN but i dind not found a way to grep the password out of the ldm (other then a keylogger :-)). Is this a known problem and is there maybe a workaround/fix??
10:06
markosu: create a test user by hand and copy the home dir after some clean up to /etc/skel
10:08
<markosu>
der_baer: thx
10:12
<der_baer>
under ubuntu (unity) the menuitems are saved within dconf so it is enought to just copy .config/dconf/user but for Lubunu I'm not so shure about it
10:13
mm no ldm guru around ??

<[conrad]>
ello everyone. I'm using 12.04 and just recently installed a new NIC, and now my LTSP doesn't work anymore. Specifically the DHCP server isc-dhcp-server. I originally thought it wass because my interface went from eth1 to eth4, but I got that resolved ( it's now eth1 ). Trying to start the server via init or service results in a failure, and there is nothing in syslog, just "error code 1" in kern.log .
14:37
Hello*
14:39
<Hyperbyte>
[conrad], see output of /var/log/syslog
14:40
<[conrad]>
Hyperbyte: As per my previous message, there is nothing in syslog being reported. Just "error code 1" in kern.log
14:44
<Hyperbyte>
Is there a dhcpd.log?
14:44
<[conrad]>
Not in /var/log
14:45
<Hyperbyte>
[conrad], meh... run service manually with output to standard output:
14:45
dhcpd -d -f
14:47
<[conrad]>
No subnet declaration for eth1 (192.168.0.1).
14:47
** Ignoring requests on eth1. If this is not what you want, please write a subnet declaration in your dhcpd.conf file for the network segment to which interface eth1 is attached. **
14:48
The thing is, everything is configured exactly how it was before.
14:49
<Hyperbyte>
Pastebin your /etc/dhcp/dhcpd.conf

Don't you mean /etc/ltsp/dhcpd.conf ?

14:54gdi2k has joined IRC (gdi2k!~gdi2k@120.28.233.55)
14:55
<ogra_>
[conrad], and your /etc/dhcp/dhcpd.conf is still in place (it is used to include the ltsp config)
14:56
<Hyperbyte>
[conrad], pastebin the output of: ls -al /etc/dhcp/dhcpd.conf
14:56
Also, looking at your dhcpd.conf... no dynamic range, no unknown clients - is this correct? You only have the 7 static clients in your network?
14:57
<[conrad]>
My apologies, the issue appears to be that someone in fact did try and modify this config file. You'll notice two instance of "client202" in that config file I pastebin'd
14:57
<Hyperbyte>
[conrad], something else that came to mind - what you just pasted, is not an error message. It's a notice. There should be a real error, or else dhcpd would just start up and not hand out leases.

Welcome back. Haha, for a moment there I thought you ragequit. :P
15:00
<[conrad]>
:-) Nah. I needed to pass the config file to get the actual error ( IE sudo dhcpd -d -cf /etc/ltsp/dhcpd.conf ), which reported that duplicate entry. Just so happens someone was trying to do that at the same time we were replacing the NIC.
15:00
<ogra_>
[conrad], did you fiddle with the settings in /etc/default ?
15:00
normally dhcpd does self tests and prints issues with the config
15:01
unless you force a device in /etc/default (which you shouldnt do)
15:02
<[conrad]>
ogra_: Everything is all set. Someone modified the /etc/ltsp/dhcpd.conf with a bad entry for a new host. This is resolved now.
15:02
Hyperbyte: Thanks for the help. Sorry for wasting your time.
15:03
<ogra_>
[conrad], right, just saying ... dhcpd usually does a self test on start if there is no interface forced, so you would have gotten that info right away

any recommendation besides LDM_DIRECTX = TRUE to improve the frame per second rate on the clients side?

i use a lot the epoptes streaming

from server to clients

Check ethernet flow control. Also, if you have an old epoptes version, get the patch about multithreaded broadcasting.

And, vnc isn't designed for video broadcasting... you'd need video streaming in that case
16:02
<Ark74>
alkisg, does the epoptes ppa has the patch?
16:02
<alkisg>
Which version do you have? Yes, it has it.l
16:03
<Ark74>
good then i have that covered already
16:03
<alkisg>
http://www.epoptes.org/documentation/lan-benchmark
16:03
Check that when you have the opportunity
16:04
<Ark74>
of course

how can i ask the ltsp bot about one subject? xD

19:08
<Ark74>
bad xD
19:08
<vagrantc>
Ark74: it probably doesn't have an entry for what you're looking for if it doesn't find "flow"
19:09
it only knows what we tell it
19:09
ltsp`: learn flow-control as under construction, come back another time
19:17
<Ark74>
yeah i see
19:18
vagrantc, do you know which log should i look so i can be sure that the flow control is enabled (on the ethernet card)
19:18
...
19:18
and affecting me

<alkisg>
Ark74: the lan benchmark I linked will tell you if you have flow control issues
20:25
It's the best way to see it; you cannot reliably check some flag etc
20:26
!learn flowcontrol as https://help.ubuntu.com/community/UbuntuLTSP/FlowControl
20:26
<ltsp`>
The operation succeeded.
20:27
<alkisg>
!lan-benchmark
20:27
<ltsp`>
lan-benchmark: If you have a mixed-speed network (gigabit server<=>switch connection, and 100 Mbits/sec clients<=>switch connections), then you might suffer from the !flow-control issue. To benchmark your LAN with epoptes, see http://www.epoptes.org/documentation/lan-benchmark
20:29
<bennabiy>
!flow-control
20:29
<ltsp`>
flow-control: https://help.ubuntu.com/community/UbuntuLTSP/FlowControl
20:32
<Ark74>
alkisg, i did the test and it used the 100Mbps on a single client and 50-50 on 2 clients. SO i think is ok. But again when streaming it only uses ~45 Mbps total (on both clients) and the streaming is not really good.
20:32
<alkisg>
Ark74: no gigabit?!
20:32
Ah, you mean 200 mbps in total?
20:33
<Ark74>
alkisg, yeah 100Mbps, this is a test LAN
20:33
<alkisg>
Then there's no point in testing flow control
20:33
The server <=> switch connection should be gigabit
20:34
And also again, vnc is not designed for broadcasting video
20:34
You need video streaming for that
20:34
<Ark74>
ok, the that's what is happening
20:34
<alkisg>
Set up a stream with vlc and use epoptes to tell all the clients to play it back
20:35
<Ark74>
on the real ltsp network we have a mixed 100/1000
20:35
lan
20:35
<alkisg>
Or use gstreamer on the "teacher" pc to have multiple outputs to all the "student" monitors with any gstreamer-based program, e.g. totem
20:36
OK, do the lan-benchmark there
20:36
<Ark74>
with the same issue, so maybe the reason as *you already point it out* is VNC
20:36
<alkisg>
You should be getting about 4-5 frames per second
20:36
If you get less, you might have the flow control issue
20:37
You can't really get more with vnc
20:37
<Ark74>
i'll run the benchmark there and also set vlc to stream
20:38
alkisg, yet another question about it, could it be that the client video card is on the MoBo with 8MB??
20:39
wouldn't it matter?
20:39
<alkisg>
No
20:39
When streaming video with vlc, on thin clients, it would matter if the card didn't support xvideo
20:39
But it doesn't matter with vnc
20:40
<Ark74>
!xvideo
20:40
<ltsp`>
Error: "xvideo" is not a valid command.
20:40
<Ark74>
xD no luck with the ltsp-bot
20:40
hahaha
20:40
ok, i'll run those tests before i run into xvideo/videocard support
20:40
xD
20:41
<alkisg>
xvinfo tells you if you have xv support
20:41
But it doesn't matter at all for vnc, browsing etc
20:41
It only matters when you play a video with a real video player
20:44
<Ark74>
ok, thanks for the info and mostly your time :)
