How to Install Ocserv on OpenBSD

Ocserv is an open-source SSL VPN server that allows you to securely connect to your network from anywhere. In this tutorial, we will guide you through the process of installing Ocserv on OpenBSD.

Prerequisites

Before we begin, you need to have the following:

• A machine running OpenBSD.
• A user account with root privileges.
• Basic command-line knowledge.

Step 1: Install Dependencies

The first step is to install the dependencies required to build Ocserv. Open the terminal on your OpenBSD machine and run the following command:

sudo pkg_add gnutls libev libseccomp

This will install GnuTLS, libev, and libseccomp libraries on your system.

Step 2: Download and Install Ocserv

Next, we need to download the Ocserv source code from the official website:

wget https://ocserv.gitlab.io/www/downloads.html

Now extract the downloaded file using the following command:

tar zxvf ocserv-<version>-tar.gz

Replace <version> with the version number of the Ocserv you downloaded.

Now navigate into the extracted directory:

cd ocserv-<version>

To configure the package run:

./configure

After the configuration, you can build and install Ocserv by running:

make
sudo make install

This will build and install Ocserv on your system.

Step 3: Configure Ocserv

Once Ocserv is installed, you need to configure it to work with your network. The default configuration file for Ocserv is located at /usr/local/etc/ocserv/ocserv.conf. You can modify the configuration file to suit your needs.

sudo nano /usr/local/etc/ocserv/ocserv.conf

Make the necessary changes to the configuration file as per your requirements.

Step 4: Start Ocserv

After configuring Ocserv, we can start the Ocserv service by running:

sudo ocserv

This starts the Ocserv service in the foreground. If you want to run it in the background, add the -f flag:

sudo ocserv -f

Conclusion

That's it! You have successfully installed Ocserv on OpenBSD. You can now connect to the Ocserv server from any client machine. Make sure to configure your firewall to allow traffic to the Ocserv server to enable remote clients to connect to your network.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
