Hello and welcome to this comprehensive guide on Debian X11VNC Server. In this article, we will discuss everything you need to know about setting up and configuring X11VNC Server on Debian. Whether you are a seasoned Linux user or a beginner, this guide is for you. We will cover a wide range of topics from installation to troubleshooting and everything in between. So, without further ado, let’s dive in.
Chapter 1: Introduction
Debian is a popular Linux distribution known for its stability and security. X11VNC is a VNC server that allows remote access to the desktop of a Debian-based system. It is a lightweight and efficient tool that enables users to access and control a Debian system remotely. In this chapter, we will discuss the basics of X11VNC server and why you might need it.
What is X11VNC Server?
X11VNC Server is a VNC (Virtual Network Computing) server that allows remote access to the desktop of a Debian-based system. It creates a virtual display that can be accessed remotely using a VNC viewer. X11VNC is different from other VNC servers as it does not create a new display for each remote connection. Instead, it shares the existing display with the VNC client.
Why might you need X11VNC Server?
There are several reasons why you might need X11VNC server. For example:
| Reasons | Description |
|---|---|
| Remote administration | X11VNC server allows system administrators to remotely access and manage a Debian-based system, which can be particularly useful for troubleshooting and maintenance. |
| Remote support | If you are providing remote support to a client, X11VNC server allows them to share their desktop with you, making it easier to diagnose and fix issues. |
| Remote access | If you need to access your Debian system remotely, X11VNC server allows you to do so from any location with an internet connection. |
Now that we have a basic understanding of X11VNC server, let’s move on to the next chapter where we will discuss how to install it on Debian.
Chapter 2: Installation
In this chapter, we will discuss how to install X11VNC server on Debian. We will cover both the command line and GUI methods of installation.
Command Line Method
The command line method of installation is the most straightforward. Open a terminal and type the following command:
sudo apt-get install x11vnc
GUI Method
If you prefer a GUI, you can use the Software Center to install X11VNC server. Follow these steps:
- Open the Software Center from the Applications menu.
- Search for X11VNC.
- Click on the X11VNC package and click Install.
Once the installation is complete, we can move on to the next step – configuring X11VNC server.
Chapter 3: Configuration
Now that we have installed X11VNC server, we need to configure it. In this chapter, we will discuss how to configure X11VNC server on Debian.
Creating a Password
To secure your X11VNC server, you should create a password that will be required for remote connections. You can use the following command to create a password:
x11vnc -storepasswd
Follow the prompts to enter your desired password.
Starting X11VNC Server
Once you have created a password, you can start X11VNC server by running the following command:
x11vnc -forever -usepw
This will start X11VNC server and keep it running indefinitely. The -usepw option tells X11VNC to use the password you created earlier.
Autostart X11VNC Server
If you want X11VNC server to start automatically when your Debian system boots up, you can use systemd. Follow these steps:
-
- Create a systemd service file.
- Edit the file and add the following lines:
[Unit]Description=X11VNC ServerAfter=multi-user.target-
[Service] ExecStart=/usr/bin/x11vnc -forever -usepwUser=[username]-
[Install] WantedBy=multi-user.target
- Replace
[username]with the username of the user who will be running X11VNC server. - Save the file as
x11vnc.service. - Copy the file to the following directory:
/etc/systemd/system - Reload systemd:
sudo systemctl daemon-reload
-
- Enable the service:
sudo systemctl enable x11vnc.service
Now, X11VNC server will start automatically when your Debian system boots up.
Chapter 4: Advanced Configuration
In this chapter, we will discuss some advanced configuration options for X11VNC server. These options can be used to customize the behavior of X11VNC server and enhance its functionality.
Changing the Resolution
You can change the resolution of the X11VNC server by using the -geometry option. For example, to set the resolution to 1920×1080, use the following command:
x11vnc -forever -usepw -geometry 1920x1080
Enabling Encryption
X11VNC server does not encrypt its traffic by default. To enable encryption, you can use the -ssl option. For example:
x11vnc -forever -usepw -ssl
This will enable SSL encryption for your X11VNC server.
Limiting Connections
You can limit the number of connections to your X11VNC server by using the -ncache option. For example, to limit the number of connections to 10, use the following command:
x11vnc -forever -usepw -ncache 10
Chapter 5: Troubleshooting
In this chapter, we will discuss some common issues you might encounter when using X11VNC server and how to troubleshoot them.
Connection Refused
If you are unable to connect to your X11VNC server, you might see a “connection refused” error message. This can happen if your firewall is blocking the VNC port (5900). To fix this, you can open the port by using the following command:
sudo ufw allow 5900/tcp
Black Screen
If you see a black screen when you connect to your X11VNC server, it might be due to a permissions issue. To fix this, you can try running the following command:
xhost +SI:localuser:[username]
Replace [username] with your username.
High CPU Usage
If you notice that X11VNC server is using a lot of CPU, it might be due to a misconfiguration. You can try disabling any unnecessary options and limiting the number of connections to reduce CPU usage.

FAQs
What is the default password for X11VNC?
X11VNC server does not have a default password. You will need to create a password using the x11vnc -storepasswd command.
Can I use X11VNC server on other Linux distributions?
Yes, X11VNC server can be used on other Linux distributions, not just Debian-based systems.
What VNC viewer should I use?
There are many VNC viewers available, but we recommend using TightVNC or RealVNC as they are both free and reliable.
Can I use X11VNC server over the internet?
Yes, you can use X11VNC server over the internet, but we recommend using SSL encryption to secure your connection.
What is the difference between X11VNC and TigerVNC?
X11VNC server is a lightweight and efficient VNC server that shares the existing display with the VNC client. TigerVNC, on the other hand, creates a new display for each remote connection. Both are good options, but X11VNC is better suited for low resource systems.
