On the server, create a new /etc/openvpn/nf file and add the following: dev tun0 In the server's /etc/openvpn directory, run the following command to generate a static key: # openvpn -genkey -secret static.keyĬopy this static key to the clients /etc/openvpn directory using a secure channel like scp or sftp. You may also ping the server to test it can be reached: ping 10.9.8.1. 21:32:32 Initialization Sequence Completed 21:32:32 2012 WARNING: this configuration may cache passwords in memory - use the auth-nocache option to prevent this 21:32:32 Peer Connection Initiated with SERVER_IP:PORT Note that, if you kill openvpn (e.g., with Control-c in its console), you will not see the above network interface.
