@Roux-Guillaume Bonjour première chose il faudrait installer que le client sur les postes élèves et le master sur le poste prof.. Est-ce le cas ? Fred

Hello, I have several teaching rooms with two master computers in operation. It is important that each master computer needs its own private key. I.e. the students' computers each get a public key of Master 1 and Master 2. Master 1 then has its own private key, Master 2 too. A private key for both masters does not work.

@fred Thanks Fred, exactly as you said, updated Veyon service to 4.7.4 and they all appeared. Much appreciated, Andy

@RNETuband Bonjour Effectivement avec le bouton de la barre horizontale du haut cela fonctionne, mais pas en faisant clique droit sur la vignette d'ordinateur a diffuser Fred
