Ubuntu Servers :: Installing LTSP When Using A Separate DHCP And TFTP?
Mar 17, 2010
I want to install Ubuntu LTSP on top of an already existing system. However, I want to use a different DHCP and TFTP server. Do I simply just install 'ltsp-server-standalone' with apt and run 'sudo ltsp-build-client', stop the DHCP and TFTP server and stop them from starting automatically? Would I then just copy over the pxelinux.cfg/default file from /var/lib/tftpboot along with the initrd.img and vmlinuz images to the TFTP server?
Edit: Do I need to actually copy the whole /var/lib/tftpboot/ltsp directory over to the TFTP server?

In Jaunty (9.04) I've setup a small (eleven-terminal) ltsp network at the local school. It handled around 6600 working hours with ease.
Now I've upgrade the server to Karmic Koala (9.10) and it just stopped working.
1) The clients have PXE NICs
2) They get the proper IPs from the DHCP server and respond appropriately to changes in the DHCP configuration files.
3) DHCP server also points the clients to
filename=/ltsp/i386/pxelinux.0
4) When the clients try to download the pxelinux.0 over tftp they just timeout
5) /etc/inetd.conf has an entry like
tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot
6) The file /var/lib/tftpboot/ltsp/i386/pxelinux.0 exists on the server
I'm lost at all these configuration files and protocols.

I am still puzzled by IT guru who still install a server version of Linux using the default partition system. I am curious about what the IT guys in this forum think about this, even when the server is part of a cluster.

When I try to pxe boot a Sun X4100 (which actually has a RHEL OS on it right now) I get the message TFTP open timeout. All traffic is allowed for port 69 udp in both directions. I do get a dhcp address. I see that both on the server and the client it gets an IP. After that I get this message in the logs:

I have an embedded device for which I've created an html configuration page. This page allows you to set static IPs, dhcp, and can scan for wireless devices.My problem is that in order to access the device it requires that it runs as a dhcp server otherwise people are not assigned an IP and so can not access the embedded devices static IP. (This config page is for the laymen and so they are not the type who are able to set up their own static IPs). One of the potential options is to have the device connect to the network on eth0 acting as a dhcp client. However this prevents me from running a dhcp server.One solution I can think of is running a dhcp server only if it doesn't detect another dhcp server running on the network.

We have a combination of Red Hat Enterprise AS 3.0 and LTSP 4.2. There are 100+ users connected to a single server through Thin Client due to which the server is overloaded and degrades the performance. So I want to know how to install LOCAL APPS on LTSP 4.2 so that I can reduce the load on server.

Version 9.10 had been installed via the alternate CD as the LTSP Server Edition. In place upgrade to 10.4 completed normally via Update Manager. However, LTSP terminal boot now fails with error "Forbidden directory" and "Access Violation". The following was found . Ubuntu 10.4 uses tftp-hpa. Either this is a change from Ubuntu 9.10 or the default behaviour of tftp-hpa has changed. So now, the filename argument given in /etc/ltsp/dhcpd.conf must include the full pathname. The previous requirement was to exclude the chroot path. If this is documented somewhere, I missed it. And after modifying /etc/ltsp/dhcpd.conf, do not forget to restart the dhcp daemon $ sudo /etc/init.d/dhcp3-server restart

I am trying to setup a TFTP server and followed these instructions in setting up TFTP-HPA.
[URL]
I pretty much followed every step but commented out these two lines from the /etc/xinet.d/tftp.
# only_from = 172.31.0.240/28
# interface = 172.31.0.252
Do we really need the lines if I am allowing any machine to connect? And I have only 1 network card. This is acting as a dedicated TFTP server.I ask as I get an error on the get and put commands as below:
tftp> get xxx.txt
tftp: error received from server <File not found>
tftp: aborting
However although it gives an error it DOES GET the file.The put command however does NOT put the file. I have nobody / nogroup setup for the directory permissions as well.
tftp> put .vimrc
tftp: error received from server <File not found>
tftp: aborting

I got myself a HP t5000 series Thin client to use on my LTSP 10.04. I changed the Bios to boot PxE. When i restart the thin client it asks for a DHCP and finds the LTSP-DHCP server all is good. Its got a IP address ok, the boot process starts. ok I get the Splash screen for Ubuntu. and all is going well. ok I no get a login screen. All is going very well. (As normal with Ubuntu). I can login all is good the login starts and i get the start up sound.But then where normally one would expect to get a desktop, one gets a login screen. Not knowing the full boot procses im not sure where to start to look. Knowing linux there would be a log file somewhere, that stores the LTSP Terminal Bootup/login process and would tell me where its stopping/failing.
The good news is that when i boot a fat client in all works ok and i an able to get in with a desktop.

I setup Ubuntu 10.10 (edubuntu) along with ltsp. I have an environment with a windows network (192.168.1.0) and a subnet (192.168.0.0) that the new terminal server is on. Everything seemed to be connecting properly, but when I attempted to boot the first client, I get the error message: "Cannot connect to NBD server".

I have it working fine when tftp and dhcp are installed on the same server but when trying to forward to a remote tftp it does not work. Dnsmasq insist on giving its local ip.I have added to config:dhcp-boot=pxelinux.0,pxetest2,192.168.0.130and I tried with and without the original hcp-boot=/var/lib/tftpboot/pxelinux.0Not much on this topic on the google nor on the dnsmasq homepage.

When I run the command << kiwi-ltsp-setup -n >> the process gets to the point where it starts "Retrieving repository 'http:__download.opensuse.org_update_11.3' metadata" What do I change so that it will read from my local update repository. The local update repository is already listed in my yast repositories while the ttp:__download.opensuse.org_update_11.3 is not.

I am currently running LTSP on Ubuntu 10.04. It is a dual gig nic setup with 16GB of ram and dual AMD quad core 2.4s. I installed all the latest updates as well as likewise-open so we can use AD authentication. When testing the configuration in the lab, I boot 32 clients that successfully reach the login screen. Here comes the interesting part, I can log in, using all unique AD accounts, up to 22 clients. When I attempt to log in to the 23rd client LTSP hangs. If I restart a client it will retrieve an IP address, but TFTP will eventually time out. All of the clients are connected to a Gigabit switch along with the server so network speeds are not an issue. When I run system monitor it only shows 3.6GB of memory in use and the processors are all under 10% utilization. I have beating my head against this issue for 2 days .

I've successfully built my server, and any fat or thin client that I connect to it boots wonderfully, with great response. I've gone through this exercise because we need a more efficient way of testing computers before delivery to our customers. So, I'm trying to run Passmark's BurnInTest. I've run it before with previous versions (9.something, I think) and it worked well, but I needed to build a new server so we can test more computers concurrently, so I figured I'd get the latest release.
My problem occurs when I try to run BurnInTest - it must have root access to test the local USB, parallel, and serial ports, and the optical drive. For the previous iteration I used a script that dropped into a local xterm session, su'd to a root session, and called the BiT GUI. In this attempt, the same scripts, even when I single-step them manually, results in 'authentication failure' when the su is attempted.
I have enabled the root account and created a password for it in the chroot /opt/ltsp/i386, and rebuilt the image, multiple times, no joy. Using ctrl-alt-F1 I can log in as root, and using dmesg I can see the USB device register when I connect it, so as far as I can tell the root account is alive and well, just not available in a local xterm session for some reason.

In internets there are lot of successless stories installing ltsp on ubuntu 10.04. Most problems are in ndb, init scripts and somewhere else, which are hardly debuggable. It seems like ubuntu 10.04 has ltsp packages completely broken and abandoned. Have someone succeeded to install ltsp on 10.04 without hard brainfucking? Maybe it's better to install ltsp from scratch, or choose another distribution?

I upgraded my Edubuntu 10.10 LTSP server to 11.04 and I've lost my network. The server boots fine but none of the workstations connect. They start the boot process but hang-up as it starts to load the GUI.The screen on-which the computers hang displays Ubuntu 10.10.Do I have to manually update the LTSP image?

I've been asked to investigate the possibility of using LTSP in our school to provide a more "real world" programming environment to our students. We have a Windows 2003 Server domain and no plans to change it.I've set up the LTSP server, joined the domain and everything seems to be working fine, I can login to the LTSP server with a student account.
The next thing I want to achieve is give the students access to their "My Documents" folder on the Windows 2003 server. Is it possible to have a student log on to the terminal server (who has never logged in before) and have it automatically mount their share on the windows server?

I have been working/implementing LTSP based thin clients now using Ubuntu 10.04 LTS 32bit server. I intend to change the default purple Ubuntu splash. I have already removed the "quiet splash" parameters in the pxeconfig file. And it works, giving me a text boot. But what i needed was a replacement for the splash.

You are running tftpd as an on demand server i.e. it is only fired up when it is needed. Services run by xinetd are always run on demand. Have you actually tested if tftp on another system can access your PC i.e.
Code:
tftp your_pc_ip_address
