VNC Mirror Mode: Understanding the Differences Between Mirror Mode and Control Mode

# Introduction

## 1.1 What is VNC?

Virtual Network Computing (VNC) is a remote desktop control technology that allows users to control a computer's desktop remotely over a network. VNC achieves remote control by transmitting the image of the screen from the server side to the client and receiving the client's input.

## 1.2 VNC Application Scenarios

VNC is widely used in remote technical support, remote education, remote work, and other fields, helping users to access and operate other computers remotely.

## 1.3 Introducing the Themes of VNC Mirror Mode and Control Mode

In the process of VNC remote control, the two common modes are mirror mode and control mode. These two modes provide flexible solutions for different needs. Next, we will delve into the principles, applications, and differences of these two modes.

# Understanding VNC Mirror Mode

Virtual Network Computing (VNC) is a graphical desktop system for remote access and control of computers. VNC mirror mode is a mode of operation for VNC that allows users to view the desktop of a remote computer, but they cannot perform actual control operations. Next, we will详细介绍 VNC mirror mode.

### 2.1 What is VNC Mirror Mode?

VNC mirror mode is a mode of operation for VNC that allows users to view the desktop of a remote computer on their local computer but cannot perform operations. Users can only passively observe the screen activities of the remote computer and cannot perform mouse or keyboard input operations.

### 2.2 How to Set Up and Use VNC Mirror Mode?

To use VNC mirror mode, you first need to run the VNC server on the remote computer and the VNC client on the local computer. By specifying the IP address and port number of the remote computer, the user can connect to the remote computer and view its desktop in mirror mode.

The following is a simple example code written in Python, demonstrating how to connect to a remote computer using VNC mirror mode:

import pyvnc

remote_host = "***.***.*.***"
vnc_port = 5901

vnc_client = pyvnc.VNCClient(remote_host, vnc_port)
vnc_client.connect()
vnc_client.start_mirror_mode()

### 2.3 Advantages and Characteristics of VNC Mirror Mode

- **Real-time monitoring**: Users can monitor the desktop activities of the remote computer in real-time, suitable for remote technical support and monitoring scenarios.
- **Reducing accidental operations**: Since control operations are not possible, the risk of accidental operations can be reduced.
- **Connection stability**: The mirror mode usually has better stability, suitable for scenarios that require long-term observation of the remote computer's state.

# Understanding VNC Control Mode

In this chapter, we will delve into VNC's control mode, including its definition, setup, usage, advantages, and characteristics.

#### 3.1 What is VNC Control Mode?

VNC control mode is a method of remote control that allows users to directly operate the graphical user interface on a remote host. Users can connect to a remote host via VNC client software, view and control the desktop environment of the remote host in real-time, and perform file ope
