Ubuntu VNC installation and configuration tutorial: allows you to quickly achieve remote access and control
Overview:
VNC (Virtual Network Computing) is a remote control technology , which allows users to remotely control another computer over the network. On Ubuntu systems, we can use VNC to achieve remote access and control. This article will provide detailed installation and configuration steps, with specific code examples, to help you quickly achieve remote access and control.
Prerequisites:
Before you start installing and configuring VNC, make sure you are connected to the Internet and are using the Ubuntu operating system.
Step 1: Install VNC server
Open the terminal and install the VNC server through the following command:
sudo apt-get update sudo apt-get install vnc4server
After the installation is completed , we need to configure the VNC server to create and set up a VNC session. Run the following command to set the VNC password:
vncpasswd
Enter and confirm the password you want to set. Make sure the password is strong enough and remember it as you will use it to authenticate when connecting remotely.
Step 2: Configure VNC server
Open the terminal and start the VNC server through the following command:
vncserver
This will be You create a default VNC session, for example: :1.
In a new VNC session, configure the settings of the VNC server. Edit the ~/.vnc/xstartup
file with the following command:
nano ~/.vnc/xstartup
In the file, delete the comment (#) before the xterm
command and add the following two Line of code:
#!/bin/bash startxfce4 &
Save and close the file.
Restart the VNC server for the configuration to take effect:
vncserver -kill :1 vncserver
Step 3: Set firewall rules
If you use If you are using Ubuntu 20.04 or higher, please skip this step.
If you are using Ubuntu 18.04 or lower, please follow the steps below to set up firewall rules:
Open a terminal and install via the following commandufw
Firewall:
sudo apt-get install ufw
Enable firewall:
sudo ufw enable
Add VNC service rules:
sudo ufw allow 5901/tcp
Restart the firewall for the rules to take effect:
sudo service ufw restart
Step 4: Remote connection and control
Summary:
This article provides detailed steps for installing and configuring VNC server on Ubuntu systems, with specific code examples. By following these steps, you can quickly access and control your Ubuntu server remotely. Using VNC technology, you can easily work and collaborate remotely between different devices. At the same time, remember to set firewall rules appropriately to protect your server security. Good luck with your remote operations!
