What Linux flavor is easy to set up for RDP to auto login as Windows user from server at boot
03:51
Something kind of out of the box ready, or with a good easy guide to set up for this purpose. Thank you

hi im currently using ltsp with ubuntu 12.04. i want to connect to a cisco vpn with the network manager. the problem is that the fatclients network cards isnt managed by the network-manager and wont connect. i tried to set managed=true in /etc/NetworkManager/NetworkManager.conf but now the fatclient won't boot anymore (can't connect to cifs). is there a way to use the network manager with ltsp and cifs?

<JustSomeGuy>
is it possible to manage the network interface of a client and still boot it?
11:27
<Hyperbyte>
!ask | echo JustSomeGuy
11:27
<ltsp>
JustSomeGuy ask: Don't ask to ask a question, simply ask it, and if someone knows the answer, they'll respond. Please hang around for at least a full hour after asking a question, as not everybody constantly monitors the channel.
11:28
<JustSomeGuy>
uh i should read my questions before hitting enter sry
11:28
i meant is it possible to manage the network with the "network-manager" that comes with ubuntu on a client?
11:29
i tried to set managed=true in /etc/NetworkManager/NetworkManager.conf but now the fatclient won't boot anymore (can't connect to cifs)
11:32PhoenixSTF has joined IRC (PhoenixSTF!~rudi@lidet.uac.pt)
11:37
<vmlintu>
JustSomeGuy: The wired connection on ltsp clients is brought up way before network-manager starts, so the connection is setup already
11:38
JustSomeGuy: If you start managing it with network-manager, it looses its IP, I think, so the client looses its nbd connection to the server
11:41
<JustSomeGuy>
vmlintu, what can i do about that?
11:41
vmlintu, can i tell the client to reconnect after loosing the ip?
11:42
<vmlintu>
JustSomeGuy: when it looses the connection, the applications usually don't work anymore
11:42
JustSomeGuy: why do you want to use network-manager?
11:43
<JustSomeGuy>
vmlintu, i need the network-manager to use vpnc
11:43
vmlintu, i already tried the cli version but the configuration we get from our vendor sadly only works with the network client :/
11:44
uh i mean it only works with the network-manager-vpnc module
11:44
and the network-manager will only establish a connection if a managed wired connection is avaivable
11:49
<vmlintu>
It doesn't work if there's wifi connection?
11:49
Or any other type?
11:50
I've never used vpnc, so I don't know what it exactly needs, but I wouldn't try to solve it by giving the nbd client connection interface to network-manager
11:53
<JustSomeGuy>
we dont have wifi in our clients just wired connections und yeah i think its a "feature" of network-manager to check if there is a connected interface but network-manager apparently can only check managed interfacess hence the activation of "managed=true" in the configuration
11:53
i remember that there was an option of ndb-proxy to reestablish a connection (we used it with our failover system) but i can't remember where to activate that
12:17
<Zaphoid>
Sorta got the auto-login working, but the lts.conf located in the tftp directory is still ignored.
12:19
JustSomeGuy: I've never had luck with NetworkManager managing an interface with any kind of network based root filesystem.
12:19
JustSomeGuy: Be it plain ole nfs root filesystem, or LTSP, never works reliably.
12:35
<JustSomeGuy>
Zaphoid, yeah im currently searching how to enable the persist mode for the nbd-client in ubuntu maybe that will work :/

Hello all
13:44
Been away from LTSP for a while, last used it back on 4.2
13:44
Just trying newest version from Ubuntu repositories and have an issue
13:45
Seems the latest versions run over SSH for security? My client is booting but X is very slow to respond, thin client CPU use show high utilisation on SSH when I move the mouse etc.
13:46
Is there a way to disable SSH use for the time being so I can perform testing with out it?
13:48
<Hyperbyte>
!directx
13:48
<ltsp>
directx: If you want to turn off encryption to the workstation, which will speed up performance at the cost of security, you need to specify LDM_DIRECTX=True in your lts.conf file. Type !docs in IRC to get a link to the current documentation

Breakthrough:
16:01
I have been using the lts.conf embedded in the image.
16:01
I have now deleted that and instead use a new lts.conf created in /var/lib/tftpboot/ltsp/i386
16:02
Setting LDM_Direct=True in there is allowing fast right click menu to display, but no Ubuntu Dash panel or other items
16:02

hi
16:10
<Zaga>
need help
16:10
I'm trying to change the resolution on thin clients
16:11
I tried to put SCREEN_02="shell", to execute X -configure
16:11
but I get the shell and getty at the same time
16:12
anyone?
16:13
<jbassett>
Page 44 in the PDF manual appears to describe X configuration, i'm new to this version though so don't take my word for it
16:13
havent made it that far myself yet
16:14
<Zaga>
going to take a look at it
16:15
<jbassett>
try something like X_MODE_0 = 1024x768 in lts.conf
16:19
System is now running fast using SSH encryption, but I am unable to see the main menu and top dash bar with clock etc. Right click menu and directory icons on desktop appear though.

On fat client boot, I'm seeing LTSP core client init script fail
20:49
Errors above are /sbin/init-ltsp: 1: eval: : not found
20:49

20:50
This was right after I did a ltsp_build_client
20:54
<vagrantc>
what was your boot commandline?
20:54
<Zaphoid>
append ro initrd=initrd.img root=/dev/nbd0 init=/sbin/init-ltsp quiet splash plymouth:force-splash vt.handoff=7 nbdroot=:ltsp_amd64
20:54
<vagrantc>
my hunch is it hasn't successfully set up the aufs/overlayfs mount
20:54
<Zaphoid>
As a note, using Ubuntu 12.04
20:55
<vagrantc>
not mint?
20:55
<Zaphoid>
Well, building from mint
20:55
building using:
20:55
sudo ltsp-build-client --dist=precise
20:55
Mint 13 is the host (built around 12.04). Enjoy the LTS aspects
20:55
<vagrantc>
sure
20:56
Zaphoid: do you have scripts in /usr/share/ltsp/plugins/ltsp-build-client/Mint (or whatever "lsb_release --codename --short" outputs)
20:56
<Zaphoid>
I had this working, but had too many wrong steps in the original image. So rebuilt and now I'm stopping there. Can't figure out what I'm doing differently.
20:56
<vagrantc>
Zaphoid: dpkg --root=/opt/ltsp/i386 -l ltsp-client-core
20:57
it might have built a chroot without all the ltsp bits
20:57
<Zaphoid>
Outputs Maya
20:57
I have...
20:57
<vagrantc>
er, lsb_release --dist --short ?
20:57
no, it's got enough ltsp to run ltsp-init
20:57
er, init-ltsp
20:58
<Zaphoid>
no such option: --dist
20:58
Distributor ID: LinuxMint
20:58
Description: Linux Mint 13 Maya
20:58
Release: 13
20:58
Codename: maya
20:59
In /usr/share/ltsp/plugins/ltsp-build-client I've linked LinuxMint -> Ubuntu and LinuxMint-functions -> Ubuntu-functions
20:59
Which is what worked last time
20:59* vagrantc forgets the exact option
20:59
<vagrantc>
lsb_release --id --short
20:59
right, it would need at least that much
20:59
<Zaphoid>
LinuxMint is the output from that
21:00
I did a lsb_release --all, works well :P
21:01
I hate running into these sorts of things. Was ready to move on from this as it was working great before I rebuilt

21:03
<vagrantc>
best to learn how to rebuild it on your own time, rather than when it breaks randomly
21:04
<Zaphoid>
Very true
21:06
Because I will have to be rebuilding this in the future.
21:10
<vagrantc>
i have had half a mind to get some upstream support for it based on bennabiy's work, but haven't had the time and have lots of other projects going on
21:15
<Zaphoid>
I understand how that is.
21:15
As I said, I got it working (mostly). I'm likely going to start with plain old ubuntu in the near future, because there's no point in having mint be the host.
21:16
Same work on fat client, either way.
21:18
<vagrantc>
indeed.
