In our ltsp installation, we are experiencing lag cases also when students type in the terminal. The server is a hp 6xdual core w/64gb ram. The netork is gifa

What could be possible causes? We use ubuntu 12.04 ltsp w/gnome fallback

Whenever I boot a thinclient on a ltsp-cluster config, it says that the thinclient isn't configured yet, also it does says the same about the cluster (CLUSTER_CONFIGURED=no). What am I doing wrong?
13:19
The thinclient booting is logged on ltsp-cluster-control, altough no other kind of event is recorded.

good day
17:06
perhaps you can help. I recently installed LTSP and also the client
17:06
however when running the client it starts up shows ubuntu screen and then brings up target filesystem doesn't have request ......etc...
17:06
any ideas please
17:09
hello
17:23
<gvy>
try either photographing or writing down the exact error message
17:24
if you bother to write it down on a paper or a notebook it's googlable and askable :)

<jdouglas>
Does LTSP require a LTSP server to run? We have many windows servers in our test environment, Can we just install LTSP over a Ubuntu client and have it auto connect to an RDP session on our Windows TS server/ HyperV VHD server?
19:43
<slackish>
jdouglas: yes
19:44
<lee>
I am about as far from an expert as you're likely to get, but you could make LTSP boot clients into kiosk mode, and have it configured to run an RDP client to do that
19:44
<vagrantc>
reheh: that's almost certainly your problem
19:45
reheh: it's probably getting the wrong information the second time it boots ... you might be able to get away with using "ipappend 3" and setting nbdroot in the pxelinux configuration...
19:45
!ipappend
19:45
<ltsp>
ipappend: o temporarily solve DHCP problems in the initramfs, try putting IPAPPEND 3 after the APPEND line in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default. More info: http://www.syslinux.org/wiki/index.php/SYSLINUX#IPAPPEND_flag_val_.5BPXELINUX_only.5D
19:46
<jdouglas>
Where could I find more detailed instructions on making LTSP boot the clients into Kisok mode?
19:46
<vagrantc>
you don't need kiosk mode specifically, just SCREEN_07=xfreerdp ... <xfreerdp_opts> in lts.conf
19:47
!rdp
19:47
<ltsp>
I do not know about 'rdp', but I do know about these similar topics: 'RDP-localdev', 'freerdp'
19:47
<vagrantc>
!freerdp
19:47
<ltsp>
freerdp: http://www.freerdp.com/ is a new RDP implementation which is more actively maintained than rdesktop. Newer LTSP versions support SCREEN_07=xfreerdp <params>.
19:47
<vagrantc>
man lts.conf for more info
19:53
<reheh>
@vagrantc can i just disable the DHCP Server and leave the LTSP up
19:53
or is there a HOWTO to have multiple DHCP Servers?
19:55
<||cw>
you can disable dhcp, as long as you add the appropriate entries to your other dhcp server
19:56
otherwise the clients won't be able to find the ltsp
19:56
<vagrantc>
reheh: you shouldn't have two dhcp servers.
19:56
<||cw>
also, I've seen some nics PXE firmware only support doing tftp from the dhcp host itself
19:56
<vagrantc>
!proxydhcp
19:56
<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
19:56
<vagrantc>
proxydhcp is another option
19:58
<reheh>
well i have a Windows Domain that clients are receiving their addresses, i am just testing the thin client
19:58
<vagrantc>
proxydhcp should be fine, unless your other DHCP server is also running network boot services...
20:02vagrantc has left IRC (vagrantc!~vagrant@freegeek/vagrantc, Quit: leaving)
20:03
<reheh>
thank you will try the proxy
20:04
if i have solely the LTSP Server will i still be able to send IP leasing to windows clients
20:08
<jdouglas>
Apparently the /var/lib/tftpboot/ltsp/i386/lts.conf file and folder do not exist on my current Ubuntu workstation. I have installed "Start LTSP-Live" from the Ubuntu app store
