Next, we can generate a client certificate and key pair. Step 6: Generate a Client Certificate and Key Pair
#OPENVPN CONFIG VERIFICATION#
This might take a few minutes to complete.Īfterwards, we can generate an HMAC signature to strengthen the server’s TLS integrity verification capabilities: We can generate a strong Diffie-Hellman keys to use during key exchange by typing: Towards the end, you will have to enter y to two questions to sign and commit the certificate:Ĭertificate is to be certified until May 1 17:51:16 2026 GMT (3650 days)ġ out of 1 certificate requests certified, commit? y

Once again, the prompts will have default values based on the argument we just passed in ( server) and the contents of our vars file we sourced.įeel free to accept the default values by pressing ENTER. You will also have to modify the /etc/openvpn/nf file later to point to the correct. For instance, when copying the generated files to the /etc/openvpn directroy, you will have to substitute the correct names. Note: If you choose a name other than server here, you will have to adjust some of the instructions below. Start by generating the OpenVPN server certificate and key pair. Next, we will generate our server certificate and key pair, as well as some additional files used during the encryption process. Step 5: Create the Server Certificate, Key, and Encryption Files Organizational Unit Name (eg, section) :Ĭommon Name (eg, your name or your server's hostname) :Įmail Address now have a CA that can be used to create the rest of the files we need. If you enter '.', the field will be left blank. There are quite a few fields but you can leave some blankįor some fields there will be a default value, What you are about to enter is what is called a Distinguished Name or a DN. You are about to be asked to enter information that will be incorporated OutputGenerating a 2048 bit RSA private key Towards the bottom of the file, find the settings that set field defaults for new certificates. We only need to worry about a few of these. Inside, you will find some variables that can be adjusted to determine how your certificates will be created. To configure the values our CA will use, we need to edit the vars file within the directory. Move into the newly created directory to begin configuring the CA: To begin, we can copy the easy-rsa template directory into our home directory with the make-cadir command: In order to issue trusted certificates, we will need to set up our own simple certificate authority (CA). This means that it utilizes certificates in order to encrypt traffic between the server and clients.

The needed software is now on the server, ready to be configured.
#OPENVPN CONFIG INSTALL#
To update your server’s package index and install the necessary packages type: We will also be installing the easy-rsa package, which will help us set up an internal CA (certificate authority) for use with our VPN. OpenVPN is available in Ubuntu’s default repositories, so we can use apt for the installation. To start off, we will install OpenVPN onto our server. When you are ready to begin, log into your Ubuntu server as your sudo user and continue below. The linked tutorial will also set up a firewall, which we will assume is in place during this guide. You can follow our Ubuntu 16.04 initial server setup guide to set up a user with appropriate permissions. You will need to configure a non-root user with sudo privileges before you start this guide. To complete this tutorial, you will need access to an Ubuntu 16.04 server. For this reason, please be mindful of how much traffic your server is handling. Note: If you plan to set up an OpenVPN server on a DigitalOcean Droplet, be aware that we, like many hosting providers, charge for bandwidth overages. This tutorial will keep the installation and configuration steps as simple as possible for these setups. In this tutorial, we’ll set up an OpenVPN server on a Droplet and then configure access to it from Windows, OS X, iOS and Android. OpenVPN is a full-featured open source Secure Socket Layer (SSL) VPN solution that accommodates a wide range of configurations. You can circumvent geographical restrictions and censorship, and shield your location and any unencrypted HTTP traffic from the untrusted network. When combined with HTTPS connections, this setup allows you to secure your wireless logins and transactions. The traffic emerges from the VPN server and continues its journey to the destination. Want to access the Internet safely and securely from your smartphone or laptop when connected to an untrusted network such as the WiFi of a hotel or coffee shop? A Virtual Private Network (VPN) allows you to traverse untrusted networks privately and securely as if you were on a private network.
