The LTSP server associated with the thin client module of Zentyal counts on many more advanced configuration options. In case you want to use one of the options not mentioned here, the interface gives you the option to add it as a name-value pair in the lower part of the form Other options [7].

Each one of these profiles will have some associated clients, that will be defined through the Zentyal objects High-level Zentyal abstractions.

The local applications will allow to run some applications in the thin client hardware. This can be useful option if the applications are creating too much load for the server or network traffic. As you can see in the following section, to make this work, it is necessary to enable the Local applications in the General configuration tab.

In the context of LTSP you can find a series of differences between thin clients and fat clients. The most important differences are:

You might want to deploy a infrastructure where from a central server you can serve different images and/or configurations, depending on the network objective that you wish to serve. To do this, Zentyal offers the possibility to configure profiles.

After this you are informed that Zentyal will proceed with the creation of the image. You can follow the progress through a widget available in the Dashboard.

As you can see, it is possible to update the image. This will allow to update the core of the operating system or the local applications within the image. Through this menu you can also configure those applications that will be considered as local applications.

This configuration might be useful if, as usual in LTSP, the computers are used randomly by different people. For example, if you have a computer in a computer class that any person can use, you can avoid management of personal passwords.

If this option has been enable, as mentioned in the previous section, it is possible for a thin client to login directly depending on its MAC address.

Once the necessary applications/environments are installed, you can start building the image by going to Thin clients tab Create thin client images. Here you choose the hardware architecture compatible with the client hardware, if you wish the clients to act as thin or fat clients [6] and finally click on Create image.

Through the configuration form associated with the profile (similar to the general configuration), you can decide whether for each one of the parameters you want to apply the values defined in the general configuration or other specific values.

To start with, you have to create the images that will be sent through the network to your thin clients. In the context of thin clients you must take into consideration that the applications will be run on the operating system of the server, expect for the local applications or fat clients that will be mentioned later in this chapter. Therefore you must install a desktop environment and all the other applications that you wish to use on the thin clients.

Once the images are created and the server is configured, you can configure the clients to download and run them. In the first place you need to make sure that the DHCP module will notify when the images are available. This can be done with Zentyal’s own DHCP module.

Once the DHCP is configured, you will need to make sure that you clients have Network boot as the first boot option, generally this is configured through the BIOS of the computer.

Once the process has finished, you can see the list of available images by returning to the Thin clients tab Create thin client images.

Obviously the users that can login in the thin client will be configured through Zentyal’s Directory Service (LDAP) module. You will need to enable the PAM mechanism to be able to log in the thin client using the LDAP users.
