Setting Up Your Own VPN on Ubuntu 22.04 with ocserv

Want to create a secure and private connection to your home network from anywhere in the world? This is where ocserv comes in. It's a powerful open-source VPN server that's easy to set up on your Ubuntu 22.04 system. Let's dive in and learn how to install and configure ocserv on your machine.

Why Choose ocserv?

ocserv is a versatile and reliable VPN server that offers several advantages:

  • Open Source: Being open-source, you can inspect the code and ensure transparency.
  • Security: ocserv employs strong encryption protocols like TLS to protect your data.
  • Performance: It's known for its efficient handling of connections, delivering a fast and reliable VPN experience.
  • Easy to Configure: While powerful, ocserv is straightforward to set up, even for beginners.

Step-by-Step Installation on Ubuntu 22.04

Let's get started with the installation process:

  1. Update your system: Before installing any software, make sure your Ubuntu 22.04 system is up to date.

    sudo apt update && sudo apt upgrade

  2. Install necessary packages: ocserv requires a few dependencies to work correctly.

    sudo apt install build-essential libtool autoconf libpcap-dev

  3. Download and configure ocserv:

    • Download the latest version of ocserv from the official website.

    • Unpack the downloaded archive.

    • Configure ocserv by running:

      ./configure --prefix=/usr/local --sysconfdir=/etc/ocserv
      • Note: This command specifies the installation directory and the location for the configuration file.

  4. Compile and install:

    make
sudo make install

  5. Create the configuration file:

    • Navigate to the ocserv configuration directory.
    • Create a new file called ocserv.conf.
    sudo nano /etc/ocserv/ocserv.conf

    • Add the following configuration settings:

      # Configuration file for ocserv
log_level = 3

# Server address and port
listen_address = 0.0.0.0
listen_port = 443

# Public key and certificate
tls_cert_file = /etc/ocserv/ocserv.crt
tls_key_file = /etc/ocserv/ocserv.key

# Specify which users can connect
#  (Replace 'your_user' with your desired user)
users = your_user

  6. Generate TLS certificates:

    • Use the openssl command to create a self-signed certificate for ocserv.

      sudo openssl req -newkey rsa:2048 -nodes -keyout /etc/ocserv/ocserv.key -x509 -days 365 -out /etc/ocserv/ocserv.crt

    • You will be prompted to enter information about your organization and domain name. This information is not critical for testing, but it's good practice to provide accurate details.

  7. Start the ocserv service:

    • Use the systemctl command to start the ocserv service.

      sudo systemctl enable ocserv
sudo systemctl start ocserv

  8. Verify the installation:

    • Check the ocserv logs for any errors:

      sudo journalctl -u ocserv

    • If everything is running smoothly, you should see a message indicating that ocserv is listening on the specified port.

Accessing Your VPN

Now that ocserv is up and running, you can connect to your VPN from any device.

  1. Install an OpenVPN client: You can find various OpenVPN clients for different operating systems.

  2. Configure the client:

    • Import the public certificate (/etc/ocserv/ocserv.crt) into your OpenVPN client.
    • Set the server address to your public IP address (e.g., 192.168.1.100) and the port to 443.
    • Enter your username and password (the same as your Linux user account).

  3. Connect to the VPN: Establish a connection using your OpenVPN client.

Advanced Configuration

You can customize ocserv further to suit your specific needs:

  • Client Authentication: Implement user authentication to restrict access to specific users.
  • Traffic Routing: Configure routes to direct specific traffic through the VPN.
  • DNS Settings: Modify DNS settings to improve privacy and security.

Important Notes:

  • Make sure your router is properly configured to allow incoming traffic on the port used by ocserv (443 by default).
  • Consider using a strong password and enabling two-factor authentication for added security.
  • Regularly update your ocserv installation to benefit from the latest security patches.

Conclusion

Installing and configuring ocserv on your Ubuntu 22.04 system provides a secure and customizable VPN solution. You can now enjoy a private and encrypted connection to your home network from anywhere in the world. Remember to prioritize security and regularly update your setup to stay protected.
