How To Fix Remote Desktop Authentication Error in Ubuntu 22.04 from Win 10

Ubuntu 20

In this article, we will guide you through the process of setting up a remote desktop connection from a Windows 10 machine to Ubuntu 22.04. We will also address the common issue of authentication errors and provide solutions to fix them.

Prerequisites

Before we begin, ensure that you have administrator access to both the Windows 10 and Ubuntu 22.04 systems. You should also have a stable internet connection between the two machines.

Step 1: Install xrdp on Ubuntu

The first step is to install xrdp on your Ubuntu machine. xrdp is an open-source Remote Desktop Protocol (RDP) server that allows you to connect remotely to your Linux system. To install xrdp, open the terminal and run the following command:

sudo apt install xrdp

The sudo command is used to execute the following command with root privileges. apt is the package handling utility in Ubuntu, and install is the command to install a new package. xrdp is the name of the package we want to install.

Step 2: Check the xrdp Service Status

Once installed, you need to check if the xrdp service is active and running. Use the following command:

sudo systemctl status xrdp

The systemctl command is used to control the systemd system and service manager. status is used to view the status of a service, in this case, xrdp.

Step 3: Start the xrdp Service

If the xrdp service is not running, you can start it with the following command:

sudo systemctl start xrdp

Here, start is used to initiate the xrdp service.

Step 4: Enable xrdp Service on Boot

To ensure the xrdp service starts automatically whenever your system boots, run the following command:

sudo systemctl enable xrdp

The enable command is used to set the service to start on boot.

Step 5: Open Port 3389 in the Firewall

The next step is to allow incoming connections for RDP through the firewall. By default, xrdp uses port 3389. Use the following command to open this port:

sudo ufw allow from any to any port 3389 proto tcp

ufw stands for Uncomplicated Firewall, and it’s a frontend for iptables. allow from any to any port 3389 proto tcp allows incoming TCP connections from any source to any destination on port 3389.

Step 6: Check the IP Address of Your Ubuntu Machine

To connect to your Ubuntu machine from your Windows 10 machine, you need to know the IP address of your Ubuntu machine. Use the following command to find it:

ip a

Look for the IP address starting with “192.168.x.x”.

Step 7: Connect from Windows 10

On your Windows 10 machine, open the Remote Desktop application and enter the IP address of your Ubuntu machine. Make sure you are logged out of Ubuntu or use a different user account before attempting to connect remotely.

Troubleshooting Authentication Errors

If you are still experiencing authentication errors, it could be due to additional configuration issues. You can refer to the official xrdp documentation for more detailed instructions and troubleshooting steps.

In conclusion, setting up a remote desktop connection from Windows 10 to Ubuntu 22.04 can be done in a few steps. However, resolving authentication errors may require additional troubleshooting and configuration. We hope this guide has been helpful in setting up your remote desktop connection.
