Step 2: Select a district or image from the list of images. I would suggest you go for the latest version of your operating system, for example, Ubuntu 20.04 LTS.

Don’t worry if you want to set up a website and do other activities on the web. Their cheapest plan will cover all of it for an individual.

Step 4: You can rename the Linode label to whatever you want. After that, choose a strong password and upload the SSH key. You can do this later.

Step 5: Lastly, tick the Private IP box and click on Create.

Create Your VPN: Generating SSH Keys

Step 1: Open the terminal command on your operating system. On Linux, it is available in the applications section, and for Windows, you have to open a power shell with administrator privileges.

Step 2: Either way, after you open the terminal command, type Add-Windows Capability -Online -Name Open SSH.Client ~~~0.0.1.0.

Step 3: Furthermore, type ~ssh-keygen -t rsa -b 4096 and press enter.

Step 4: Once again, press enter when the command terminal will ask for a key location to save it to the default one. Then enter your password and tap enter.

Step 5: After that, your server will start, and you’re ready to log in. Furthermore, copy the IP address from the server control panel by going back to the terminal command and typing ssh root@139.162.245.193.

Step 6: Type yes and press the enter key.

Updating The Packages

Step 1: Update your operating system and software. To do that, type apt-get update && apt-get upgrade, and the updation will automatically start.

Step 2: You can also upgrade your favourite text editor.

Create A Non-Root User

While many users are okay with not adding another layer of password for their authentication, some are paranoid and would prefer to enter a password along with the two-factor authentication to protect their data. If you are one of those users, then read further.

Step 1: In the terminal command, type useradd – G sudo -m your username -s /bin/bash.

Step 2: Enter your local password and then enter your new password twice, and you’re all set.

Create Your VPN: Configuring SSH

After you have set your user profile, you have to copy the public SSH key to the server. To do that:

Step 1: Open a second terminal window for your local terminal and enter ssh-copy-id username and IP address.

Step 2: It will prompt you to enter your user password to authenticate. Furthermore, go back to the terminal window with your server but don’t close the other window yet.

Step 3: At this point, you have to restrict the authentication to the public key only.

Step 4: To edit the SSH configuration, we have to change the default port, but it will not do much for security. However, it will help in dealing with the obnoxious SSH scanners that try to log into your server with fake credentials.

Step 5: Take any available port and disable the passwords. Furthermore, you will only be able to log in using a Public key password and disable root login.

Step 6: In addition, save the file, restart the SSHD servers using system ctl, and restart sshd.

Step 7: Go back to the local machine and log in with the key. If it prompts you to enter your password, you will be good to go.

In comparison to other VPN, OpenVPN has wider support for client applications.

Moreover, if you want to use this VPN for all your traffic, download tunnel blick on mac, Open VPN on Windows or load it into the network manager on Linux. After this, the server will think you’re from somewhere else and cannot locate you when you start searching for something.
