======= 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
  * **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.

===== Prerequisites =====

  * **All the client PCs must already been added to a lan group in LServeradmin management**. For general information (see [[en:software:lserver-admin:lan]]). The following are the brief steps. 
  - [[en:software:lserver-admin:quickstart:startlserveradmin|We start LServerAdmin application]] as administrator.
  - **We create a new PC group** e.g. //Lab 1// - [[http://www.lserveradmin.gr/help/html_en/manual/lan/langroups.html|PC Groups]]
  - **We add all lab PCs** that boot from network to the above group - [[en:software:lserver-admin:lan:lanaddpc:lanaddltspclient]]
  - **We add a user** from teachers groups as a **Italc PC group Administrator** - [[en:software:lserver-admin:italc:teacheruseradmin|Manage Italc PC Groups]]

 
===== Start Italc =====

<note>We will work on a **teacher's PC with __local OS installation__** Linux or Windows (not booting from network). It is recommended, although not needed for Italc, that this PC is already been added to LServerAdmin management, (see [[en:software:lserver-admin:lan]]).</note>
  - **We connect to a teacher's PC.**
  - In a browser **(firefox recommended)**, on the address we type **https://hosta:8006** and connect as user **teacher**.
  - **We select the virtual machine** with the OS we want to use for our lesson, e.g. Windows or Linux (ltsp) and click on **Console**
    - **Demostration on Windows OS**
      - **We connect with a teacher account** that [[en:software:lserver-admin:italc:teacheruseradmin#add_administrator|has already been added]] as an administrator of Italc PC groups (see [[en:software:lserver-admin:quickstart:connect2windowsvm#via_proxmox_gui|connect to Windows virtual machine from proxmox]]).
      - We can change resolution from within Windows the way we know. A resolution of **1024x768** __and not greater__ is recommended for compatibility reasons with the client PC screen resolutions and for better performance.
      - We start Italc from menu **All Programs / Italc**
    - **Demostration on Linux OS**
      - **We connect with a teacher account** that [[en:software:lserver-admin:italc:teacheruseradmin#add_administrator|has already been added]] as an administrator of Italc PC groups, to the virtual machine running Linux (ltsp).
      - We can change resolution from with Linux (from menu we click on **Run** and type **lxrandr**). A resolution of **1024x768** __and not greater__ is recommended for compatibility reasons with the client PC screen resolutions and for better performance.
      - We start Italc from menu **System Tools / Italc**

    - If client PCs that **boot from network** connect to **Windows** we select **Lab 1-windows**
    - If client PCs have **local installations** and have already been added to LServerAdmin administration we select **Lab 1**
  - We **double click on Client PCs** we want to control or **right click on the group** and select **Show all computer in classroom** to show them all.
  - On the top bar on the right we click on the button **Auto View** (if it is hidden we click on the arrow to show it).
