A simple configuration

This recipe will demonstrate how to set up a connection in the client or server mode using certificates.

Getting ready

Install OpenVPN 2.3.9 or higher on two computers. Make sure the computers are connected over a network. Set up the client and server certificates using the previous recipe. For this recipe, the server computer was running CentOS 6 Linux and OpenVPN 2.3.9 and the client was running Fedora 22 Linux and OpenVPN 2.3.10.

How to do it...

1. Create the server configuration file:

           proto udp 
           port 1194 
           dev tun 
           server 10.200.0.0 255.255.255.0 
    
           ca   /etc/openvpn/cookbook/ca.crt 
           cert /etc/openvpn/cookbook/server.crt 
           key  /etc/openvpn/cookbook/server.key 
           dh   /etc/openvpn/cookbook/dh2048.pem 
   

   Then save it as example2-2-server.conf.

2. Copy over the public certificates and the server private key from the /etc/openvpn/cookbook/keys directory:

         [server]$ cd /etc/openvpn/cookbook
         [server]$ cp keys...
