Introduction to VPN and VPS: Exploring the Basics

As we shift to a digital work ethic, online security is vital for individuals and organizations. A VPN is very useful here. It secures the use of internet connectivity, conceals IP addresses, and supports secure and confidential internet use.

VPS is an inexpensive and scalable web hosting solution. It is capable of accommodating various solutions, such as websites to applications.

If you Set Up a VPN on Your VPS, It will offer both of these uses grouped together. The VPS provides the user with dedicated capabilities to create a safe tunnel to transfer data. This arrangement enhances internet security, enables access to geo blocked content and prevents data leakages.

Open VPN is a powerful and well-rounded VPN in use today. It is a great means of establishing a secure connection. This process teaches users to set up a VPN server. They can use it for personal browsing or to secure a space for remote businesses.

Understanding Virtual Private Networks (VPN) & Virtual Private Server (VPS)

Virtual Private Networks (VPN) in turn deploy encrypted and secure connection with a less secure network such as the Internet. A VPN adopts tunneling protocols.

 It lets people send and receive info as if their devices were on a private network. This setup boosts privacy. It also protects data from hackers.

VPNs are used for many reasons. They provide remote access to an organization’s network and allow access to geo-blocked content. They conceal identity when one is surfing the web. VPNs also aid in encrypting information as this ensures that this information is not seen by unauthorized viewers. This renders them ideal to any user that has concerns regarding internet confidentiality.

A Virtual Private Server (VPS) on the other hand is a type of virtualized server resembling dedicated server functionality by using only parts of a larger physical server. It provides resources of the server such as CPU, RAM, and RAM to its users. It shares the hardware with other VPS instances. 

This solution is more convenient and flexible than shared hosting. For businesses and developers who require a customized setup or software on their servers, VPS makes sense. Applications, websites, and catalogs that need more server power than shared hosting usually offers will find VPS hosting especially helpful.  VPS uses virtualization. It lets multiple users share one main server, each with a distinct virtual environment. The technology is both efficient and economical.

Setting Up a VPN on a VPS: Step-By-Step Guide

It takes several important steps to set up a VPN on a VPS. They guarantee a functional and safe association.

To begin with, when it comes to the fact that you do not have a VPS, you should pick a reliable provider. They will have to ensure that they perform well and are safe. Once registered, you have to configure a new server, typically by choosing an operating system. Once you have signed up on your VPS, enter this server, via an SSH client, e.g. PuTty or OpenSSH. The second task after the successful log in is to update the server and this will make sure that the software is up to date.

With that done, it is now time to build a VPN on your new VPS.

1. Installing VPN Software on Your VPS

To set up a VPN on a VPS, choose a compatible VPN protocol. Then, follow the simple installation steps. This will ensure that the connection is as strong as possible.

A. Choosing a VPN Protocol

Among the major concerns during the setup of VPN is what VPN protocol should be used. Open VPN, wireguard, PPP, and L2TP/IPsec are the most popular ones.

• OpenVPN is characterised by good security and flexibility. It is compatible with numerous operating systems.
• WireGuard is, however, faster, has less overhead, and is more inexpensive. It is associated to be very simple and very powerful performing.
• Older protocols are PPTP and L2TP/IPsec which were easier to install. However, they are not as secure as the OpenVPN and wireguard.

A protocol should address the requirement of the organization in terms of security, speed, and devices compatibility.

• Install EasyRSA:Assuming you have not yet installed EasyRSA, then you can run:

sudo apt-get install easy-rsa

• Setup EasyRSA: you will create a directory called EasyRSA and navigate into it:

make-cadir ~/openvpn-ca
cd ~/openvpn-ca

• Start the PKI: Start the Public Key Infrastructure. This is necessary because it is the preparation step of your server that issues certificates.

./easyrsa init-PKI

• Create the Certificate Authority (CA): Construct the CA to sign your certificates of servers and clients.

./easyrsa build-ca

• Complete the instructions to generate a secure passphrase.
• Generate Server Certificate and Key: Sign and generate a server certificate request.

./easyrsa gen-req server nopass

./easyrsa sign server server

• Generate Client Certificate and Key: Similarly, create and sign a certificate request for the client.
  

./easyrsa gen-req client nopass

./easyrsa sign client client

• Generate Diffie-Hellman Parameters: This step is crucial for key exchange:

./easyrsa gen-dh
