How to install and configure VNC on Debian 11

VNC (VNC) is an access protocol that is used for remote desktop management (for example, when a technician works with a client or when an employee accesses data from home). SSH or VPN is required to use Virtual Network Computing securely. The step-by-step instructions on how to install and configure VNC on Debian 11 involve a number of steps.

Connecting to the server

To do this, you need to know the IP address. To connect with root privileges, use the command

ssh root@IP_DEL_SERVER

Similarly, you can connect under a user with other privileges (but in this case, replace the word root with your name:

ssh username@IP_DEL_SERVER

To connect via ssh, use the standard port 22.

Installing the desktop environment

For full-fledged work with VNZ you need to install Desktop Environment (DE). The options are different, depending on the specific case:

XFCE or Mate Desktop - for low-resource environments;

Gnome - for servers with high resource level.

The desktop environment is installed with the command sudo apt install task, in which you need to add the selected DE. For example:

sudo apt install task-gnome-desktop dbus-x11

How to create a user in Linux

To do this we use the command:

sudo useradd -m -s /bin/bash USERNAME

Next, we set our USERNAME with a password:

passwd USERNAME

When the username is created, you can add it to the group with the command:

sudo usermod -aG sudo USERNAME

To log in and check root permissions, use the command su - USERNAME.

Installing Debian TigerVNC Server 11

In this step we do 2 global settings:

• VNC;
• DE,

To install TigerVNC we use the command:

sudo apt install tigervnc-standalone-server tigervnc-common -y

After that we need to log in without root privileges and initialize the VNC server:

su - USERNAME

vncserver.

The system will automatically prompt us to enter the password that will be used for access. Note that it must be strong and at least 8 characters long. It will then ask if you are going to create a view-only password (for example, when you want to share the VNC server). When you complete the process, you will get information with where the VNC server is running. All that's left to do is set up the environment, add a user to TigerVNC, and connect to the server
