OpenVPN should start downloading new packages.
RSA key is being generated. It should take a long time.
After the key is generated, OpenVPN installer should ask you for your Public IP or domain name. You may leave it blank if you want. In that case, your OpenVPN server won't be accessible from the internet.
You can go to https://www.whatsmyip.org and find out your Public IP if you don't know already.

In your HOME directory a new file 'linuxhint.ovpn' or 'client.ovpn' should be generated depending on the name you used.
Now you can connect to your VPN server with the following command:
$ openvpn --config linuxhint.ovpnYour openvpn client should be connected to the openvpn server.
Run the following command to find out what network interfaces you have on your computer.
$ ip aYou should see a 'tun0' interface in the output of 'ip a' command as shown in the screenshot below. So everything worked perfectly.
That is how you install and configure OpenVPN server on Arch Linux. Thanks for reading this article.
