X11 Forwarding with Putty and Xming: Run Server Instead of Client-side?

X11 Forwarding with PuTTY and Xming on Ubuntu 24.04 LTS

X11 forwarding is a technique that allows you to run graphical applications on a remote server and display the graphical interface on your local machine. This is particularly useful when you are using a headless server or when you want to run graphical applications on a more powerful machine than your local one. In this article, we will explain how to set up X11 forwarding using PuTTY and Xming on an Ubuntu 24.04 LTS machine.

What is X11 Forwarding?

X11 forwarding is a feature of the X Window System, which is a graphical windowing system for Unix and Unix-like operating systems. X11 forwarding allows you to run X11 applications on a remote machine and display the graphical interface on your local machine. This is done by forwarding the X11 traffic from the remote machine to your local machine over an encrypted SSH connection.

Setting up X11 Forwarding with PuTTY and Xming

To set up X11 forwarding with PuTTY and Xming, you will need to perform the following steps:

1. Download and install Xming on your Windows 10 machine. Xming is an X11 server for Windows that allows you to run X11 applications on your Windows machine.
2. Start Xming on your Windows 10 machine. This will start the X11 server and allow you to run X11 applications.
3. Download and install PuTTY on your Windows 10 machine. PuTTY is an SSH client for Windows that allows you to connect to remote servers.
4. Start PuTTY and enter the hostname or IP address of the remote server that you want to connect to. In the "Connection" category, expand the "SSH" section and click on "X11". Check the "Enable X11 forwarding" checkbox. This will enable X11 forwarding for your connection.
5. Click on the "Open" button to open the SSH connection. Enter your username and password when prompted.
6. Once you are logged in, you can run X11 applications on the remote server and they will be displayed on your local machine.

Code Example

Here is an example of how to run the xeyes X11 application on a remote Ubuntu 24.04 LTS server and display it on your local Windows 10 machine:
