Setting Up an OpenVPN Server on Debian Jessie
Before we begin, make sure you have a clean installation of Debian Jessie on your server. You will also need root or sudo access to your server, as well as a static IP address.
Step 1: Install OpenVPN
The first step is to install the OpenVPN package on your server. You can do this by running the following command:
Command |
Description |
|---|---|
apt-get update |
Update the package list |
apt-get install openvpn |
Install the OpenVPN package |
This will install the OpenVPN package and its dependencies on your server. After the installation is complete, you can verify that OpenVPN is installed by running:
Command |
Description |
|---|---|
openvpn –version |
Check the OpenVPN version |
Step 2: Configure OpenVPN
The next step is to configure your OpenVPN server. OpenVPN uses a configuration file (typically named “server.conf”) that contains the settings for your VPN server. You can create a new configuration file by copying the sample file:
Command |
Description |
|---|---|
cp /usr/share/doc/openvpn/examples/sample-config-files/server.conf.gz /etc/openvpn/ |
Copy the sample configuration file |
gzip -d /etc/openvpn/server.conf.gz |
Unzip the configuration file |
After copying and unzipping the configuration file, you should edit it to match your network settings. The configuration file is well-documented and contains explanations of each setting.
Step 3: Generate Certificates and Keys
OpenVPN uses public-key cryptography to secure the VPN connection. This requires generating certificates and keys for each client that will connect to the server.
You can use the EasyRSA script included with OpenVPN to generate these certificates and keys. First, create a new directory to hold the scripts:
Command |
Description |
|---|---|
mkdir ~/easy-rsa |
Create a new directory |
Next, copy the EasyRSA scripts to this directory:
Command |
Description |
|---|---|
cp -r /usr/share/easy-rsa/* ~/easy-rsa/ |
Copy the EasyRSA scripts |
Then, edit the “vars” file to set some basic configuration options:
Command |
Description |
|---|---|
nano ~/easy-rsa/vars |
Edit the vars file |
Finally, run the “build-ca” script to generate the root certificate, and then the “build-key-server” script to generate the server certificate:
Command |
Description |
|---|---|
cd ~/easy-rsa |
Change to the easy-rsa directory |
./easyrsa build-ca |
Generate the root certificate |
./easyrsa build-server-full server nopass |
Generate the server certificate |
Step 4: Start and Test OpenVPN
After configuring OpenVPN and generating the required certificates and keys, you are ready to start the server and test it. You can start the OpenVPN service by running:
Command |
Description |
|---|---|
systemctl start openvpn@server |
Start the OpenVPN service |
You should also enable the service to start automatically at boot time:
Command |
Description |
|---|---|
systemctl enable openvpn@server |
Enable the OpenVPN service at boot time |
To test the server, you can try connecting to it from a remote client using the OpenVPN client software. You can download the client software from the OpenVPN website.
