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...
