To set up Linux OpenVPN on your system,follow these organized steps:

1. Install the OpenVPN Client (nftop):

   • Use the package manager to install nftop on your system.

     sudo apt install nftop

2. Create the Configuration File:

   • Navigate to /usr/config/nftop.conf.
   • Write the following configuration:

     nftop -G "localhost:8888" -p 443 -u "example" -h "localhost" -b

3. Set Up the Server:

   • Ensure your remote server (e.g., server.example.com) is running on port 443.
   • Update the configuration to use HTTPS:

     nftop -G "localhost:8888" -p 443 -u "example" -h "localhost" -b -protocol=https

4. Configure Remote Access:

   • Update the remote access settings in the configuration:

     nftop -G "localhost:8888" -p 443 -u "example" -h "localhost" -b host=localhost port=8888

5. Test the Connection:

   • Open a terminal and type nftop to check if it connects to the remote server.
   • If it doesn't connect, check the configuration for errors.

6. Alternative Methods:

   • If using SSH, connect via:

     ssh -i sshpublickey@domain.com -o keypair:password

   • Alternatively, connect directly through the web interface:

     https://example.com

7. Troubleshooting:

   • Check the configuration file for errors.
   • Ensure the local machine has nftop installed and up-to-date.
   • Verify the remote server is running and accessible.

By following these steps, you should be able to establish a secure VPN connection for your remote work or applications.
