I am teaching a course in a computer-class. The teacher's computer has a Windows OS and a software called "Teacher". It allows the teacher to take control over the students' computers, broadcast my desktop to them, etc.

I want to do the same with my Ubuntu laptop. Is there any software that I can install, that will allow me to act like the "Teacher" software?

I found some programs that offer "classroom control for Ubuntu", such as Classroom Management Software by Mithware or ControlAula, but they require me to install some software on the students' computers, which I cannot do. I am looking for a software with which I can connect to the existing students' computers.

EDIT: since it is not possible to control existing computers without installing a new software on them, is there a software that lets me to at least broadcast my screen to the students' screens? I found some websites that do it, like appear.in and screenleap, but they are limited to 8 viewers, while I have about 40...

    Splashtop offers this too but I guess you will always have to install something on the students computer because otherwise the door for hackers would be wide open if there would be such a tool you search fir – derHugo Oct 24 '17 at 17:09

    If you can control a remote computer without installing anything upon it...that would indeed be a staggeringly gaping security hole. You can broadcast (several applications do that) without client software, but you cannot control. – user535733 Oct 24 '17 at 17:14
  • @user535733 actually, broadcasting my screen is the most important thing that I need. How can I do this? – Erel Segal-Halevi Oct 25 '17 at 04:33
  • For merely broadcasting your desktop, see https://askubuntu.com/questions/335158/share-desktop-via-web-browser – user535733 Oct 25 '17 at 11:49

Veyon is exactly that. Veyon is the successor of iTALC

With it one can lock computers, plus remotely reboot or even shut-off machines. A good thing about it is that it is free with its source-code freely available for subsequent change to meet each user’s need. And, apart from Linux, it can also support Windows machines.

Features

It has been designed for usage in school. Therefore it offers a lot of possibilities to teachers, such as

see what’s going on in computer-labs by using overview mode and make snapshots

remote control computers to support and help other people

show a demo (either in fullscreen or in a window) – the teacher’s screen is shown on all student’s computers in realtime

lock workstations for moving undivided attention to teacher

send text messages to students

powering on/off and rebooting computers per remote

remote logon and logoff and remote execution of arbitrary commands/scripts

home schooling – its network-technology is not restricted to a subnet and therefore students at home can join lessons via VPN-connections just by installing it's client
