Attention
Fat Client configurations only apply to LTSP versions 5.2 and greater.
LTSP Fat Client - Definition / Purpose
Previous documentation indicated that LTSP lab consists of a server that supports thin (diskless clients). Therefore, then a workstation logs in and runs an application, that application is running from the server and displayed on the workstation. Although this has many advantages, due to network transports and server load, certain applications can run slow.
A fat client (in LTSP terms) is a computer lab setup whereby the application processing is performed by the client itself, thus better distributing the load.
The interesting point is that the client still does not require a hard disk.
How configure a FAT Client
- Perform the previous steps to perform an install from scratch.
- Open a terminal (shell) and login as root (eg. sudo su)
- Enter the following command to remove the current chroot configuration:
rm -rf /opt/ltsp/amd64 - Issue the following command to rebuild the system using FAT Clients:
ltsp-build-client --fat-client --fat-client-desktop edubuntu-desktop --arch amd64 --skipimage - Once the image is rebuilt, issue the following commands:
ltsp-update-sshkeys
ltsp-update-image
