Italc is a tool for remote control student PCs. It has features such as

• Teacher desktop demostration
• Student desktop demostration
• Remote control student desktop
• Lock student desktops

Italc supports both Linux and Windows Operating Systems. LServerAdmin application installs and configures italc on Client PCs on the following situations.

• Client PC with local installation of Linux or Windows (XP/7/8/10)
• Ltsp Client PC (booting from network) that connect remotely to Linux or Windows

We will see how to use the already configured Italc application for the client PCs booting from network and connecting to the Windows and Linux (ltsp) virtual machines running on server.

• All the client PCs must already been added to a lan group in LServeradmin management. For general information (see Local Network). The following are the brief steps.

1. We start LServerAdmin application as administrator.
2. We create a new PC group e.g. Lab 1 - PC Groups
