This Pi-KVM device has running kvmd-vnc daemon and provides VNC access to the server.
WARNING! We strongly don't recommend you to use VNC in untrusted networks. The current implementation does not use encryption, and your passwords are transmitted over the network in a plain text.
Your VNC client must support Tight JPEG compression, password authentication and allow connection without encryption. TigerVNC is a good choice. On Linux, this client will most likely be available for installation from the repository. It can also be called vncviewer.
