What is VNC?
Virtual Network Computing aka VNC is a desktop sharing system that enables you to control another computer remotely. Virtual network computing is beneficial if you need to access files that are contained on another computer that is located far from your zone. For connecting, you only need a TCP/IP connection, a VNC server, and a VNC viewer. To use VNC, you also need to have an idea about the VNC ports.
How to open VNC Ports?
To control another system remotely, you need to first connect to it. For this, a default port is used by VNC. The default VNC port is 5900 and for the web interface, it uses 5800. Additionally, there are various ports that we can use instead of these default VNC ports. For this, you may have to sum up the default port number and user-assigned display number. That is, if your display number is 2, you can add 5900+2 which gives you a port number 5902.
