I have a project where I need 3 computers (CLIENT) to access a single other computer (SERVER). The SERVER run VNC Server and the 3 CLIENTS run VNC Viewer. The CLIENTS only need to connect to the network and the only application that will ever run on the CLIENT computer is a VNC Viewer. I don't need to interact with the OS.
My idea is to build a Linux without GUI and to autostart a VNC Client software.
Any suggestion on how to build the CLIENT? Software and hardware suggestion?
