Italc - Remote control student PCs

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

• Teacher desktop demostration
• Student desktop demostration

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.
