LTSP – UP and Running..

Setup LTSP – Remote Boot  PXE Enabled Thin Clients or PXE enabled PC/Laptops

We would first install the Required applications step by step and then configure them later.

• 1.Install the Regular Ubuntu Desktop Distro, I am using ubuntu 9.04 for this howto.
• 2.Once Installed, update the distro and install all the necessary updates.
• 3.Once Done Install NFS kernel Server via this Command : sudo apt-get install nfs-kernel-server
• 4.Install the DHCP SERVER on the same machine,make sure there is only one dhcp server running on the network else.it will cause a conflict.
• 5.Set a static ip to the machine via /etc/network/interfaces file – i am using 192.168.0.1 as SERVER ip for this HOWTO.
• 6.Now install the server module for LTSP running this command on terminal : – sudo apt-get install ltsp-server-standalone openssh-server ( this would install the LTSP Server and the openssh on the desktop.
• 7.Now Create your Thin Client environment on the server with this command: sudo ltsp-build-client
• The First command installs the LTSP SERVER and the Second command installs the module that  will provide/create  the environment  to run the remote disk less machines. ( Please be patient, the client module takes time to install as it fetches about 150 MB of files from the repos. )

Once the client installation is done run these 2 commands to create the ssh keys

sudo ltsp-update-sshkeys

sudo ltsp-update-image

Be sure to do it in that order.

We are now done with the installation. now comes the configuration part.

• Open the /etc/default/tftpd-hpa and edit first line Run_Daemon to “Yes” in place of NO.Save and Exit.
• Now Open the /etc/ltsp/dhcpd.conf and change some values to the file as below.uncomment value next-server and put the server ip infromt of it ( next-server 192.168.0.1; )
• add these two values below that :
• allow booting;
• allow bootp;
• now go to the last line of the dhcpd.conf and it has a default value : filename (  ”/ltsp/i386/nbi.img”;  )   change that to (  filename “pxelinux.0″;  )
• Once done save and exit and restart the  dhcp server /etc/init.d/dhcp3-server restart
• Once done now u can just Boot the diskless workstations and it should aautomatically find the  dhcp server get an IP address and load the Remote OS. and Login.
