The problem with Veyon is registering student devices.Using an add-in allows you to scan the network and register devices automatically, but this comes at a cost.Since the add-in runs on the teacher, I wondered if I could do something similar.I looked into the Veyon source code.It appears that the Veyon service uses port 11100.It appears that port 11100 is open on the student's computer, so I created a Python app and registered the device information .Now the teacher can run the app on their own.Now you can manage your computers in an instant. Uses super-fast python threads. Automatically obtains subnets. Adds real-time "Locations and Computers". Easy to use.
