Remote Desktop Protocol (RDP) is a Microsoft proprietary protocol that enables remote connections to other computers, typically over TCP port 3389. To reach the port through which a remote desktop will be accessible, sum the default port and the user’s assigned display number.

If applicable, this information is appended to the network address in the Details area: In this example, VNC Server is running on host computer 192.168.

To see whether VNC Server is listening on a port other than 5900, click the VNC Server icon in the Notification Area to open the VNC Server dialog.
VNC VIEWER PORT PASSWORD
Enter the user name and password you typically use to log on to the VNC Server computer. Enter the public IP address in VNC Viewer to establish a direct connection. Look up the VNC Server computer’s public (external) IP address. Display 0 is, by convention, port 5900 display 1 port 5901 and so on, so if the port your server is using is close to 5900, you can simply subtract 5900 and use that as the display number.Ĭonfigure the VNC Server computer’s router to forward port 5900. How do I specify a port in VNC?Ī VNC display number is just another way of specifying a port. Several implementations also start a basic HTTP server on port 5800+N to provide a VNC viewer as a Java applet, allowing easy connection through any Java-enabled web-browser.

VNC by default uses TCP port 5900+N, where N is the display number (usually :0 for a physical display).
