Ubuntu Servers :: LTSP And Booting HPt5000?
Dec 4, 2010
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.

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 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".

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've just installed Ubuntu 9.10 64bit on my new server and then built a 32bit image. When I try and boot my thin clients I get the following error on VT7:
Code:

mountall: mount / [416] terminated with status 1.
mount: according to mtab, none is already mounted on /proc
mountall: mount /proc [409] terminated with status 1.

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 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?

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.

I have setup Ubuntu 9.10 ltsp server, and have the client connected with login screen. I can log on the client successfully , but I did not get to the window environment, just see a busy mouse pointer on client screen and the screen of the server is scrambled ... and not viewable. I built the image by ltsl-build-client The server is amd64 version and the client is i386 version.

I am trying to install and configure LTSP on a server for a HP thin client to boot off. The version of Ubuntu that I am using is 11.04 x86 and it is a fresh install on a dual core system with 2GB RAM. I followed a guide which comprised of these commands.
sudo apt-get install ltsp-server-standalone openssh-server sudo ltsp-build-client or if your on a 64-bit system with 32-bit machines do sudo ltsp-build-client arch i386 for editing the servers IP values use /etc/ltsp/dhcpd.conf after that you need to restart DHCP server sudo /etc/init.d/dhcp3-server restart
and update sshkeys -sudo ltsp-update-sshkeys and if you updated dhcpd.conf then you need to update you image also by typing in terminal ltsp-update-image
Everything seemed to install as it should but when I try to boot from the thin client it just times out and says no DHCP or proxy invites received. I turned DHCP off on the router and even tried another router, but I still get nothing. I am at a bit of a loose end and I hope someone on here can point me in the right direction of where I am going wrong.

I have configured server ubuntu 11.04. Everything works fine, but there is a need for some clients to connect local hard drive. What should I do? How and what modules are added to the ltsp-image? How to register in the fstab on the client? Maybe I'm going the wrong way?

I've set up a ubuntu server 8.04 with ntp-server. At boot time the ntp service is started, butCode:ntpq -pdelivers:No association ID's returned.I've set up the ntp the way to be able above my private network to use this as reference.If i restart ntp everything is fine.First i thought that the problem is that dhcp is started after ntp, but after changing the start-order in the runlevels this enigma remains.

I'm working on a (minecraft) server on some old hardware and started by installing a fresh copy of ubuntu server 11.04. After that I installed the minimal xfce system with the guide at [URL] . I've tried every trick I could find on to disable it from starting up, but it appears every time! Wierdly enough, it doesnt display any standard looking login screen, but instead displays this old looking login screen with a debian logo. Not sure how to get a screen shot of it. All I want is it to boot into a command line!

server configuration: SCSI 36gig -> sdd; boot and root as it was first in the box;2 IDE hard drives -> sda/sdb for data; and1 SATA drive -> sdc for data.After upgrading to Lucid (not right away, but a bit later), it stopped booting:'Gave up waiting for root device.'ALERT! /dev/disk/by-uuid/........... does not exist. Dropping to a shell!(initramfs)Happily, pushing ^D let it resume booting, but it kept repeating. After some study, I found the Lucid release notes that said "if you upgrade to ext4, you have to manually update Grub". A quick check showed that sdd was now, indeed ext4 - nobody told me! And, why couldn't it update Grub by itself? But, I dutifully ran grub-install and life went back to normal.
Until last night, when I updated the kernel, etc. with apt-get and restarted, and grub dropped dead:More googling turned up this solution, which I used with an install CD:http://tinyurl.com/2dhswzzWhich worked, but it brought back the first problem, and running grub-install doesn't fix it. So, what do I do now?

I have a server running 64bit lucid and while trying to get a script to run on boot to start Davmail I appear to have broken something. I have webmin installed but I have been trying to do the majority of things via the command line. I now have davmail starting at boot but a lot of other services don't start anymore, including apache, mysql and webmin. Fortunately SSH still works and I can start apache and webmin from the command line without any problems.

I want to know if there is a way to disable the GUI console on 10.04 Server I want the traditional pure text console ... no plymouth, no plymouth-theme, just 80x24 console. Another question, Is there a way to get those traditional messages when booting? Like 8.04 Server does?

I'm running Ubuntu Server 11.04 on a home PC as a local-only file and web server for some private projects.After a few minutes Ubuntu will stop responding to the network and a cold reboot is required to re-enable the NIC.I've been able to stop the above occurring with a user logged in and constantly pinging the gateway, although this is obviously undesirable.
I read here and elsewhere that a fix is to set acpi=off in grub. I have done this but now instead Ubuntu will not boot and shows the message:
do_IRQ: 1.55 No irq handle for vector (irq -1)
Disabling IRQ #34
and hangs there indefinitely. The system will boot fine if I revert the changes but obviously the sleep problem remains.The BIOS does not have an option to disable ACPI, just select S1 or S3.Is there anything else I should be looking for in order to disable sleep? Otherwise the system is working fine, and when it's awake I haven't had any other trouble.

Here's exracted from ubuntu Grub2 document https://help.ubuntu.com/community/Grub2:
GRUB_HIDDEN_TIMEOUT=0 This setting determines how long a screen without the GRUB 2 menu will be displayed. While the screen is blank, the user can press any key to display the menu.The default behavior is to hide the menu if only one operating system is present. If a user with only Ubuntu wishes to display the menu, place a # symbol at the start of this line to disable the hidden menu feature.According to above information, I have tried to set below in order the show the menu:
GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=false
GRUB_TIMEOUT="20"
