Apa itu Port 5800?

Port 5800 is used by VNC servers to serve an embedded Java applet-based web viewer, allowing browser-based remote desktop access without installing a VNC client. The HTTP server on this port serves a Java applet that connects to the VNC server on port 5900. This legacy functionality is rarely used today as Java applets have been removed from modern browsers.
