How to Configure a Jump Server to Allow Access to a Local Server Web GUI from a Remote Client Machine

In this article, we will guide you through the process of configuring a jump server to allow access to a local server's web GUI from a remote client machine. A jump server, also known as a bastion host, acts as an intermediary between the client and the local server, providing a secure connection and controlling access to the server's resources.

Before we begin, please make sure you have the following:

• A jump server (Linux-based)
• A local server with a web GUI (e.g., a web-based control panel)
• A remote client machine (Windows, macOS, or Linux)

Step 1: Install and Configure SSH Server

The first step is to install and configure an SSH server on your jump server. SSH (Secure Shell) is a widely used protocol for secure remote access.

Here's how you can do it:

1. Open a terminal or SSH client on your jump server.
2. Install OpenSSH server by running the following command:
   sudo apt-get install openssh-server
3. Once the installation is complete, open the SSH server configuration file:
   sudo nano /etc/ssh/sshd_config
4. Find the line that says #Port 22 and remove the # to uncomment it. You can also change the port number if desired.
5. Save the file and exit the text editor.
6. Restart the SSH service:
   sudo service ssh restart

Step 2: Configure Port Forwarding

Now, we need to configure port forwarding on the jump server to redirect traffic from the client machine to the local server's web GUI.

1. Open the SSH server configuration file again:
   sudo nano /etc/ssh/sshd_config
2. Add the following lines at the end of the file to enable port forwarding:
   AllowTcpForwarding yes
GatewayPorts yes
3. Save the file and exit the text editor.
4. Restart the SSH service:
   sudo service ssh restart

Step 3: Connect to the Jump Server

Now, we can connect to the jump server from the remote client machine using an SSH client.

1. Open an SSH client on your remote client machine (e.g., PuTTY for Windows, Terminal for macOS and Linux).
2. Enter the jump server's IP address or hostname in the "Host" field.
3. Specify the SSH port number if you changed it in the SSH server configuration.
4. Click "Connect" or press "Enter" to initiate the SSH connection.
5. Enter your username and password when prompted.

Step 4: Access the Local Server's Web GUI

Once you are connected to the jump server, you can access the local server's web GUI using a web browser on your remote client machine.

1. Open a web browser on your remote client machine.
2. Enter the jump server's IP address or hostname followed by the port number of the local server's web GUI. For example, http://jump-server-ip:8080.
3. You should now see the login page or the web interface of the local server's GUI.
4. Enter the necessary credentials to log in and start using the web GUI.

Congratulations! You have successfully configured a jump server to allow access to a local server's web GUI from a remote client machine. You can now manage and control your local server's resources securely.

Conclusion

In this article, we have walked you through the process of configuring a jump server to enable access to a local server's web GUI from a remote client machine. By following the steps outlined above, you can establish a secure connection and manage your local server's resources conveniently.
