Simple configuration

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

Getting ready

Install OpenVPN 2.0 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, both computers were running Linux and OpenVPN 2.1.1.

How to do it...

1. Create the server configuration file:

   proto udp
   port 1194
   dev tun
   server 192.168.200.0 255.255.255.0
   
   ca   /etc/openvpn/cookbook/ca.crt
   cert /etc/openvpn/cookbook/server.crt
   key  /etc/openvpn/cookbook/server.key
   dh   /etc/openvpn/cookbook/dh1024.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/ca.crt ca.crt
   [server]$ cp keys/openvpnserver.crt server.crt
   [server]$ cp keys/openvpnserver.key server.key
   [server]$ cp keys/dh1024.pem dh1024.pem
