<us3598>
Anyone hanging around?
01:49
Could use some LTSP setup advice
02:09
<sbalneav>
Whatchoo need?
02:12
<us3598>
So, I setup LTSP on an Ubuntu 14.04 VM, got it running so now thin clients will pull the image built, however once logged into the OS it pulls a full unity desktop (painfully slow performance), and all I need it to do is immediately RDP into our windows terminal server (preferably without tc login)
02:12
I don't even need a desktop at all, just an immediate RDP into our windows terminal server with USB device passthrough
02:12
Thanks for responding, BTW
02:13
<sbalneav>
http://wiki.ltsp.org/wiki/Integration#Rdesktop
02:13
Think that's what you want
02:15
<us3598>
Yea I found that script, but is there a way to 1: prevent the unity desktop from loading at all (since the performance is so slow RDesktop wont even render a usable screen), or switch the Unity for old scool gnome or xfce? and 2: Is there a way to bypass thin client login entirely and just (as far as the end user is concerned) pxe boot 'right into windows'
02:16
<sbalneav>
That's exactly what that does.
02:16
It doesn't load a desktop, it just runs rdesktop.
02:17
<us3598>
K, I'll give it a shot and let you know. Are you going to be hanging around for a bit?
02:17
<sbalneav>
Note: you need to make sure xfreerdp/rdesktop is installed in the chroot.
02:17
yeah, for a bit.
02:17
<us3598>
which one do you suggest?
02:19
<sbalneav>
Neither: they both are used to access windows. :D
02:24
<us3598>
Sorry, I'm kind of a noob to linux...how do I chroot into LTSP? and I can't find an lts.conf
02:27
<sbalneav>
http://wiki.ltsp.org/wiki/Ltsp-chroot
02:27
http://wiki.ltsp.org/wiki/Configuration
02:28
By default one doesn't exist
02:28
So you just have to create it
02:28
<us3598>
groups: cannot find name for group ID 127
02:28
thanks again btw :)
02:46
I get a TFTP open timeout now on the client
02:55
I've restarted the tftpd-hpa process
02:55
Still nothing...any suggestions
02:56
oops
03:05
I'm going to try ltsp from an opensuse distro, since I can't figure it out on Ubuntu
03:18
<sbalneav>
Well, I'd need to know what you did :D
03:26
<us3598>
hah, I guess so, eh? Well, first I opened gedit and created /var/lib/tftpboot/ltsp/i386/lts.conf
03:27
then I put the following in: [Default]
03:27
LDM_DIRECTX = True
03:27
SCREEN_07 = rdesktop
03:27
RDP_SERVER = 10.1.1.2
03:27
RDP_OPTIONS = "-r sound:local" '-r disk:Drives=/media/root"
03:28
and then saved, did ltsp-update-image, then tried to boot clients
03:28
I restarted the tftpd-hpa process from terminal as well, and rebooted the machine
03:31
Now I get TFTP open timeout during PXE boot.
03:40
You around still?

Just wondering what popularity of LTSP is lately. I am absolutely loving it and shocked it's not in every school, business, and home.
04:06
Is growth good?

hello?

<work_alkisg>
Hello
04:27
<us3598>
Ji
04:27
I was on here trying to get some advice about an ltsp setup....are you someone who could give a poor, overworked IT guy a hand?
04:28work_alkisg is now known as alkisg
04:28
<alkisg>
Yup, but I have limited time, so let's sum up...
04:29
You're still on Ubuntu, but haven't booted any clients yet?
04:29
<us3598>
Well, I keep getting the damned TFTP open timeout
04:29
I just installed an opensuse vm with kiwi, ame thing
04:29
<alkisg>
But, they were booting before, right? What changed?
04:30
<us3598>
Just the creation of the config file
04:30
<alkisg>
Nah, lts.conf isn't related to tftp
04:30
Maybe you have 2 dhcp servers
04:30
One in the vm and one outside, and now the outside one answers?
04:31
So they're timing out because they're looking to the wrong dhcp/tftp server...
04:31
<us3598>
Maybe, but it's still grabbing a pxe signal from the correct IP
04:31
I only have the one VM running, and stopped all tftp servers on the windows side
04:31
<alkisg>
!tftp
04:31
<ltsp`>
tftp: Here's a page to help you troubleshoot TFTP problems in Ubuntu: https://help.ubuntu.com/community/UbuntuLTSP/Troubleshooting/TFTP
04:32
<us3598>
I'll give it a shout
04:32
shot*. Thanks
04:32
<alkisg>
np, ask again once you get dhcp/tftp going, or even if you don't :)
04:33
<us3598>
The only thing bugging me is that in the OpenSuse VM, it's doing the same thing....appreciate the help
04:33
<alkisg>
It's probably wrong dhcp settings
04:33
Try `tftp get` from some other machine to verify that tftp is fine
04:33
And then use ipxe/config command to see the dhcp settings
04:34Guest17554 has joined IRC (Guest17554!~richard@174.32.164.150)
04:34
<alkisg>
You shouldn't be having 2 dhcp servers at the same network, switch to proxydhcp instead
04:34
!proxydhcp
04:34
<ltsp`>
proxydhcp: A proxy DHCP server is defined by the PXE specification as a server which sends auxiliary boot information to clients, like the boot filename, tftp server or rootpath, but leaves the task of IP leasing to the normal DHCP server. More info: https://help.ubuntu.com/community/UbuntuLTSP/ProxyDHCP
04:34
<alkisg>
...or modify your main dhcp server to point to the vm for booting
04:35
<us3598>
Gotcha...I'll give all of this a try

<Sydcul>
Hello
17:53
When I log in using my client I do get a desktop but no menu bars of anything
17:53
There is a cursor though
17:53
Running Ubuntu 14.04.1 on AMD64, client is i386
17:54
So then I found a (possible) fix on the Ubuntu forums, it stated that I had to include this in lts.conf: XRANDR_OUTPUT_0="VGA1 --off"
17:54
I tried it, but my lts.conf does not get read at all
17:55
So then I tried putting it in /opt/ltsp/i386/etc and updating the image, but I couldn't input an arch and the amd64 image won't work for my i386 client.
17:56
lts.conf has permissions 0604, also tried 774 but to no avail
17:58
Also, using getltscfg -a gets me an error, but I can use cat with the full path just fine
17:59
lts.conf: http://paste.ubuntu.com/8534496/
18:00
Hello
18:02
I don't know if IRC works so if you read this please tell.
18:02
<vagrantc>
Sydcul: so the XRANDR_OUTPUT_0 command is if it's detecting multiple monitors
18:03
Sydcul: how did you confirm your lts.conf wasn't read?
18:06
<Sydcul>
Well none of the config entries work
18:07
Besides, when using getltscfg -a (which simulates what LTSP does when it reads the config) says there's no config found
18:08
Even though it does exist

18:28
<vagrantc>
where are you running "getltscfg -a" from?
18:29
i.e. an xterm on the client? a shell running on the client? an xterm running on the server?
18:29
Sydcul_: ^^
18:29
Sydcul_: and where are you editing lts.conf ? and what's your dhcp server configuration?
19:25
<Sydcul_>
xterm from the client, using the "failsafe xterm" option
19:25
lts.conf is edited from the server
19:25
<vagrantc>
yes, but where?
19:26
i.e. /var/lib/tftpboot/ltsp/i386/lts.conf?
19:26
<Sydcul_>
The i386 directory in the tftp root
19:26
yes that one
19:26
<vagrantc>
and your dhcp configuration?
19:26
<muppis>
For some reason my PS/2 mouse doesn't work in fat client. :(
19:26
<vagrantc>
muppis: but thin client is fine?
19:27
<Sydcul_>
DHCP: http://paste.ubuntu.com/8534990/
19:27
<muppis>
vagrantc, actually I can't say right now. Haven't tested yet.
19:28
Need to wait debootstrap to finish so I can reboot.
19:28
<vagrantc>
Sydcul_: it's probably trying to download lts.conf from your router
19:28
Sydcul_: did you configure with ipappend 3 ?
19:28
<Sydcul_>
I don't know what that means, so probably, no.
19:28
<vagrantc>
Sydcul_: in /opt/ltsp/i386/etc/ltsp/update-kernels.conf
19:29
<Sydcul_>
Ok, I'll try that
19:29
Oh, I did, yes.
19:29
Using a command: sudo sed -i 's/ipappend 2/ipappend 3/g' /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
19:30
When I did not it didn't even boot into LTSP
19:30
But I could even login (into xterm)
19:34
<muppis>
vagrantc, with thin works fine. Doesn't make any difference that thin is 32 bit and fat 64 bit?

vagrantc, now building 64 bit thin for test.
19:51
<vagrantc>
Sydcul: is ldm-server installed on your server?
19:51
muppis: you know you can switch between thin and fat by setting LTSP_FATCLIENT=true/false ?
19:51
(presuming you have the desktop packages installed for a fat client)
19:52
<muppis>
I know, but I want to be sure. :)
19:53
<Sydcul>
Ok, so I had the wrong MAC address (used the wifi card's one) and forgot some config things, my lts.conf now works.
19:54
Yes, it is installed and works (sortof)
19:54
Now I still have the problem that I'm stuck on a desktop with only a cursor
19:55
I have no other computers available ATM
19:55
Except for the 2007 Sony with Core 2 Duo and 2GB RAM, so it should work (with 3D acceleration)
20:00
<vagrantc>
Sydcul: is it unity? could you try another desktop environment?
20:00
Sydcul: unity or gnome don't exactly have the best track records for thin client support
20:00
<Sydcul>
It is indeed unity
20:00
<vagrantc>
Sydcul: or are you running them as fat clients?
20:00
<Sydcul>
Would LXDE work? I'm planning on using that anyway
20:01
Thin
20:01
<vagrantc>
i've had good luck with lxde
20:01
Sydcul: your hardware is definitely nice enough to consider fat clients...
20:01
<Sydcul>
Then I'll try that, see how it goes
20:01
<vagrantc>
Sydcul: the thin client will likely be idle most of the time
20:02
<muppis>
vagrantc, just noticed.. This 32 bit is fat as well.. o.0
20:02
<Sydcul>
This isn't my definitive hardware, I am going to use this in a corporate environment with thin-client hardware
20:02
I just have the notebook for testing
20:06
vagrantc: After installing LXDE, how do I set it to be used by LTSP? I still want to use Unity on the "server".
20:06
Which is actually my dev pc.
20:13
I think I've got it.
20:15
<vagrantc>
LDM_SESSION
20:15
or LDM_FORCE_SESSION
20:15
sessions in /usr/share/xsessions/

hrm.
20:23
while that should work, it's really for backwards compatibility
20:24
really should specify the name of the .desktop file.
