How to Install Ocserv on Fedora Server

Ocserv is an open-source SSL VPN server that utilizes the OpenConnect SSL VPN protocol. In this tutorial, we're going to show you how to install Ocserv on Fedora Server.

Prerequisites

Before installing Ocserv, make sure that your Fedora Server meets the following requirements:

• A minimum of 1 GB RAM
• At least 10 GB of disk space
• Root or superuser privileges
• Internet connectivity

Step 1: Install Dependencies

First, we need to install the dependencies required for compiling Ocserv. Run the following command to install the dependencies:

sudo dnf install gnutls-devel gmp-devel libseccomp-devel pam-devel zlib-devel systemd-devel readline-devel perl

Step 2: Download Ocserv

Visit the Ocserv website here and download the latest stable release of Ocserv.

wget ftp://ftp.infradead.org/pub/ocserv/ocserv-VERSION.tar.xz

Note: Replace VERSION with the latest stable release. Check here for the latest stable release.

Step 3: Extract the Ocserv Archive

Next, extract the Ocserv archive using the following command:

tar -xvf ocserv-VERSION.tar.xz

Step 4: Compile and Install Ocserv

Now, navigate into the extracted Ocserv directory and compile Ocserv using the following commands:

cd ocserv-VERSION

./configure --prefix=/usr --sysconfdir=/etc

make

sudo make install

Step 5: Configure Ocserv

Now that we have installed Ocserv, we need to configure it. Create a new directory for Ocserv configuration files:

sudo mkdir /etc/ocserv

Copy the default configuration file to the Ocserv configuration directory:

sudo cp ./doc/sample.config /etc/ocserv/ocserv.conf

Edit the configuration file using the text editor of your choice:

sudo nano /etc/ocserv/ocserv.conf

Configure Ocserv as per your requirements. Some common configurations are:

tcp-port = YOUR_PREFERRED_PORT_NUMBER

udp-port = YOUR_PREFERRED_PORT_NUMBER

ipv4-network = YOUR_PRIVATE_IPV4_ADDRESS

ipv4-netmask = YOUR_PRIVATE_IPV4_ADDRESS_NETMASK

dns = YOUR_PREFERRED_DNS_SERVER

Note: Make sure to replace YOUR_PREFERRED_PORT_NUMBER, YOUR_PRIVATE_IPV4_ADDRESS, YOUR_PRIVATE_IPV4_ADDRESS_NETMASK and YOUR_PREFERRED_DNS_SERVER with actual values.

Step 6: Start Ocserv

After configuring Ocserv, we can start the Ocserv service using the following command:

sudo systemctl start ocserv

To start Ocserv automatically on system boot, run:

sudo systemctl enable ocserv

Step 7: Test the Connection

Now that the Ocserv service is up and running, we can test the connection. Connect to the VPN using a client that supports the OpenConnect SSL VPN protocol.

Congratulations! You have successfully installed and configured Ocserv on your Fedora Server.
