How to Install and Configure VNC on Debian 10

Putting in and configuring VNC on Debian 10 is roofed on this tutorial.

It is usually often called Digital Community Computing (VNC), and it’s a connection expertise that lets you use your keyboard and mouse to speak with a graphical desktop atmosphere working on a pc. There isn’t any must learn to use the command line to handle recordsdata and functions on a distant server.

On this tutorial, you’ll learn to arrange a VNC server on a Debian 10 server and use an SSH tunnel to entry to it safely. Quick and light-weight distant management software program TightVNC will probably be used. Our VNC connection will probably be extra dependable and fluid on account of this resolution, even on slower web connections.

To be able to end this lesson, you’ll want:

  • A non-root consumer with sudo entry and a firewall are each put in on a Debian 10 server that was arrange utilizing the Debian 10 preliminary server setup directions.
  • An SSH-enabled VNC shopper put in on a neighborhood laptop which may be used to hook up with distant hosts.
  • It’s doable to hook up with a distant laptop with TightVNC, RealVNC, or UltraVNC whereas utilizing Home windows.
  • It’s doable to make the most of a cross-platform device like RealVNC on macOS to share display screen content material.
  • Vinagre, Krdc, RealVNC, and TightVNC are just some of the quite a few options obtainable to you on Linux.


In the meanwhile, we’ll begin by putting in the mandatory parts that aren’t pre-installed on the Debian 10 server. We are going to set up the latest variations of the Xfce desktop atmosphere and the TightVNC bundle from the Debian repository’s official distribution.

Your server’s checklist of packages needs to be up to date:

sudo apt replace

Now, arrange the Xfce desktop atmosphere in your server by following these directions:

sudo apt set up xfce4 xfce4-goodies

If you happen to don’t already know what structure you need, you’ll be able to select it all through the set up course of. Press Enter to decide on the one that’s suited to your language. The set up will go on as scheduled.

The TightVNC server could be put in when the set up is full:

sudo apt set up tightvncserver

You’ll want to make use of the vncserver command to construct the essential configuration recordsdata and arrange a powerful password after putting in the VNC server.


If you wish to entry your laptop remotely, you’ll must enter and supply a password:

To get entry to your computer systems, you’ll need to offer a password.



The password have to be no less than six characters lengthy. There will probably be an automatic restriction of lengthy passwords.

Making a view-only password is feasible as soon as the password has been verified. It’s not doable to regulate VNC utilizing the mouse or keyboard of customers who’ve a view-only password. If you happen to want to present something to others by way of your VNC server, you should utilize this characteristic, though it isn’t important

After that, the server’s default configuration recordsdata and connection info are generated by the process.

Would you prefer to enter a view-only password (y/n)? n

xauth:  file /dwelling/tommy/.Xauthority doesn't exist

New 'X' desktop is your_hostname:1

Creating default startup script /dwelling/tommy/.vnc/xstartup

Beginning functions laid out in /dwelling/tommy/.vnc/xstartup

Log file is /dwelling/tommy/.vnc/your_hostname:1.log

Let’s get began with configuring the VNC server.

When the VNC server first begins up, it must know which directions to run to be able to perform correctly. VNC, specifically, must know which graphical desktop to hook up with.

The xstartup file in your house listing’s.vnc folder incorporates these directions. The vncserver command produced the beginning script, however we’ll make our personal to start out the Xfce desktop.

Within the preliminary setup of VNC, a server occasion is launched on port 5901. VNC makes use of the next identifiers to designate this port:1. VNC might run many situations on completely different show ports, comparable to:2,:3, and so forth..

Cease the VNC server on port 5901 utilizing the next command earlier than making any adjustments to the server configuration:

vncserver -kill :1

Nonetheless, you’ll discover a special PID within the output:

Killing Xtightvnc course of ID 17648

Again up the unique file earlier than making any adjustments to it:

mv ~/.vnc/xstartup ~/.vnc/xstartup.bak

Create a brand new xstartup file and open it with a textual content editor like Notepad:

nano ~/.vnc/xstartup

While you begin or restart the VNC server, the instructions on this file are mechanically carried out. If our desktop atmosphere isn’t at the moment working, we’ll want VNC to get it up and working. Add the next instructions to the file:



xrdb $HOME/.Xresources

startxfce4 &

When VNC’s GUI framework reads the consumer’s sources file, the primary command is xrdb $HOME/.Xresources. In Xresources, customers can customise the graphical desktop’s look by altering issues just like the terminal’s colour scheme, the cursor theme, and the font rendering. You will discover all of the graphical software program it is advisable to function your server in Xfce, which is launched by the second command.

We should make this new startup file executable to ensure that it for use by the VNC server.

sudo chmod +x ~/.vnc/xstartup

Restart the VNC server presently.


You’ll get one thing like this in consequence:


New ‘X’ desktop is your_hostname:1

Beginning functions laid out in /dwelling/tommy/.vnc/xstartup

Log file is /dwelling/tommy/.vnc/your_hostname:1.log

As soon as all the things is about up, let’s try to ascertain a connection to the server utilizing a neighborhood PC.


When establishing a connection, VNC doesn’t use any safe strategies. To determine a protected connection to our server, we’ll create an SSH tunnel and instruct our VNC shopper to utilize that tunnel as a substitute of a direct connection.

Arrange a safe SSH connection between your native laptop and the VNC server. Utilizing the command line on Linux or macOS, you might accomplish this:

ssh -L 5901: -C -N -l tommy your_server_ip

You’ll be able to simply arrange your desktop by utilizing the default configuration.

Utilizing the file supervisor or the command line, you might entry recordsdata in your house listing.

Press CTRL+C in your terminal to exit the SSH tunnel and return to the immediate in your native system. As well as, your VNC session will probably be terminated.

After that, we’ll create a service for the VNC server.

Within the subsequent step, we’ll create a systemd service for the VNC server, which is able to enable us to handle the server like another service. The restart of your server won’t have an effect on this.

To start, open a textual content editor and create a brand new file named /and so on/systemd/system/[email protected]:

sudo nano /and so on/systemd/system/[email protected]

A parameter could be handed in by utilizing the @ image on the finish of the title within the service configuration. Once we administer the service, we’ll make the most of this to determine the VNC show port we’d need to use.

The next traces needs to be added to the doc. Consumer, Group, WorkingDirectory, and PIDFILE’s username ought to all be modified to replicate your precise username.

/and so on/systemd/system/[email protected]


Description=Begin TightVNC server at startup

After=syslog.goal community.goal







ExecStartPre=-/usr/bin/vncserver -kill :%i > /dev/null 2>&1

ExecStart=/usr/bin/vncserver -depth 24 -geometry 1280x800 :%i

ExecStop=/usr/bin/vncserver -kill :%i


Within the occasion that VNC is already working, the ExecStartPre command places a halt to it. Utilizing the ExecStart command, VNC is began and the decision is configured to 1280×800 with a 24-bit colour depth. These beginning decisions may also be personalized to fit your necessities.

Shut and save the doc.

The subsequent step is to inform the system of the brand new unit file’s existence.

sudo systemctl daemon-reload

In your laptop, open the unit file and select “Allow”.

sudo systemctl allow [email protected]

Utilizing the @ image, the service will seem on show no 1 as talked about in Step 2..

The VNC server needs to be stopped whether it is nonetheless functioning.

vncserver -kill :1

Then, similar to another systemd service, begin it.

sudo systemctl begin [email protected]

The next command can be utilized to substantiate that it was began:

sudo systemctl standing [email protected]

If all the things went in keeping with plan, you must see one thing like this:


● [email protected] - Begin TightVNC server at startup
Loaded: loaded (/and so on/systemd/system/[email protected]; enabled; vendor preset: enabled)
   Lively: lively (working) since Thu 2019-10-10 17:56:17 UTC; 5s in the past
  Course of: 935 ExecStartPre=/usr/bin/vncserver -kill :1 > /dev/null 2>&1 (code=exited, standing=2)
  Course of: 940 ExecStart=/usr/bin/vncserver -depth 24 -geometry 1280x800 :1 (code=exited, standing=0/SUCCESS)
 Important PID: 948 (Xtightvnc)
. . .

While you reboot your laptop, your VNC server will probably be accessible.

It’s time to restart your SSH tunnel.

ssh -L 5901: -C -N -l tommy your_server_ip

Make a brand new connection to localhost:5901 utilizing your VNC shopper program to entry your laptop.


On account of this, you now have a safe VNC server working in your Debian 10 server. Along with managing your recordsdata, software program, and settings utilizing an easy-to-use and acquainted graphical interface, it is possible for you to to function graphical functions, comparable to internet browsers, from a distant location as nicely.
