Introduction
Welcome to the complete guide to setting up VPN Server Ubuntu 14.04! If you’re looking to connect to a private network securely and remotely, then setting up a VPN is your best bet. With this guide, you’ll be able to create your own VPN server with Ubuntu 14.04.
Before we dive into the details, we need to define what a VPN is and how it works. A Virtual Private Network (VPN) is a network that allows you to connect remotely and securely to a private network. By doing so, you can access the internet and other network resources as if you were physically present in the location of the private network.
In this guide, we will walk you through the process of setting up your own VPN server using Ubuntu 14.04. We will also discuss the advantages and disadvantages of setting up a VPN server and provide answers to frequently asked questions.
Let’s get started!
What is VPN and how does it work?
What is VPN?
A Virtual Private Network, commonly known as VPN, is a network that extends a private network across a public network to enable remote access to resources. VPNs work by encrypting data between a user’s device and the VPN server, creating a secure and private connection that cannot be accessed by others.
How does VPN work?
When a user connects to a VPN, their device creates an encrypted tunnel to the VPN server. The data passing through this tunnel is encrypted and secure, making it difficult for anyone to intercept or access it. The encrypted data is then sent out to the internet through the VPN server, making it appear as if the user is accessing the internet from the VPN server’s location.
VPN servers can be set up on different operating systems, including Ubuntu 14.04. Here is a comprehensive guide on how to set up VPN Server Ubuntu 14.04.
Setting up VPN Server Ubuntu 14.04
Step 1: Install and Update Ubuntu
The first step in setting up a VPN server using Ubuntu 14.04 is to install and update the operating system. This can be done by running the following command:
Command |
Description |
|---|---|
sudo apt-get update |
Updates the Ubuntu repository to ensure that all packages are up-to-date. |
sudo apt-get upgrade |
Upgrades all installed packages to their latest versions. |
Step 2: Install OpenVPN
Once Ubuntu is updated, the next step is to install OpenVPN. OpenVPN is the software that allows us to create a secure connection between the VPN server and the clients. We can install OpenVPN by running the following command:
Command |
Description |
|---|---|
sudo apt-get install openvpn |
Installs OpenVPN on the Ubuntu server. |
Step 3: Generate Server and Client Certificates
The OpenVPN server requires certificates for authentication. We need to create a certificate authority (CA), server, and client certificates for this purpose. The following commands will generate the necessary certificates:
Command |
Description |
|---|---|
sudo apt-get install easy-rsa |
Installs the EasyRSA package, which we’ll use to generate the certificates. |
cd /usr/share/easy-rsa/ |
Navigates to the EasyRSA directory. |
sudo ./easyrsa init-pki |
Initializes the Public Key Infrastructure (PKI) for the CA. |
sudo ./easyrsa build-ca |
Builds the CA certificate and key. |
sudo ./easyrsa gen-req server nopass |
Generates the server certificate and key. |
sudo ./easyrsa sign-req server server |
Signs the server certificate with the CA. |
sudo ./easyrsa gen-req client nopass |
Generates a client certificate and key. |
sudo ./easyrsa sign-req client client |
Signs the client certificate with the CA. |
Step 4: Configure OpenVPN Server
Once the certificates are generated, we can proceed to configure the OpenVPN server. We need to create a configuration file for the server and set up the firewall rules.
Step 5: Start OpenVPN Server
With the OpenVPN server configured, we can now start it by running the following command:
Command |
Description |
|---|---|
sudo systemctl start openvpn@server |
Starts the OpenVPN server. |
Step 6: Connect to OpenVPN Server
Finally, we can connect to the OpenVPN server from our client device. We need to install and configure the OpenVPN client on our device. Once configured, we can connect to the server using the client certificate and key.
