LTSP

LTSP 5 Server Installation ( Amd 64 bit / 32 bits )
1. Ubuntu alternate cd 9.10
Once you boot up the CD, hit F4. The "Modes" menu will pop up. Select "Install an LTSP Server".
Now just move on with the install.
Towards the end of the install the installer will start to build the client environment from the packages
on the CD.
Which then will be compressed into an image...
If the installer is done and has rebooted into your new system you will be able to boot your first Thin
Client right away.
Installing on top of an already running desktop system
You need to set up one static network interface where you will attach the thin clients, install two
packages and run one command.
Configure your spare interface for the thin clients to have the IP 192.168.0.1 (and make sure it is up
and running). If you can't get the new GNOME network manager to work you can always install the
older, simpler version of network manager by going to the "add/remove" window and searching
"network". Make sure to search "all available packages" and "apply" the changes. You will find the new
network manager under settings -> network. Then follow the instructions below.
sudo apt-get install ltsp-server-standalone openssh-server
Now create your Thin Client environment on the server with.
sudo ltsp-build-client
•
• If you are on a 64-bit system but your clients have another architecture use the --arch
option eg. sudo ltsp-build-client --arch i386 ( sudo ltsp-build-client -a i386 -b /opt/ltsp )
After that, you will be able to boot your first thin client. If it doesn't boot try rebooting the server.
• Note that if you want to use another IP than the above, you need to edit
the /etc/ltsp/dhcpd.conf file to match the IP values and restart the dhcp server.
Comments and hints
If you change the IP data after you have done the initial setup, please run the command sudo ltspupdate-
sshkeys to make the ssh server aware of the change.
This workstation isn't authorized to connect to server error message on client, please run commands
sudo ltsp-update-sshkeys and sudo ltsp-update-image (in this order) reference:

Dont use the ltsp-utils package from universe (only available in dapper) with this ltsp
implementation, it is for a different ltsp version, installing them together will break.
