How to install ocserv on Arch Linux

Ocserv is an open-source SSL VPN server that provides a secure and fast VPN solution. In this tutorial, we will be showing you how to install ocserv on Arch Linux.

Prerequisites

Before we start, ensure that your system is up-to-date by running the following:

sudo pacman -Syu

Installation

Install the ocserv package using the following command:

sudo pacman -S ocserv
Once the installation is complete, modify the configuration file /etc/ocserv/ocserv.conf using your preferred text editor. Ensure to remove the "#" sign in front of the following lines:
```
auth = "pam"
tcp-port = 443
udp-port = 443
max-clients = 16
server-cert = /etc/ocserv/server-cert.pem
server-key = /etc/ocserv/server-key.pem
```
Save and close the configuration file.

Generate the server SSL certificate using the following command:

sudo certtool --generate-privkey --outfile /etc/ocserv/server-key.pem
sudo certtool --generate-self-signed --load-privkey /etc/ocserv/server-key.pem --outfile /etc/ocserv/server-cert.pem

Start and enable the ocserv service using the following commands:
```
sudo systemctl start ocserv
sudo systemctl enable ocserv
```
Finally, open the necessary firewall ports by running the following command:

sudo ufw allow 80/tcp && sudo ufw allow 443/tcp

If you do not have UFW installed, you can use the following command:

sudo iptables -A INPUT -p tcp --dport 80 -j ACCEPT && sudo iptables -A INPUT -p tcp --dport 443 -j ACCEPT

Your ocserv installation is now complete, and you can begin securely connecting to the VPN server.
