OpenVPN client and daemon binary. More information: https://openvpn.net/.

• Connect to server using a config file:
   
  sudo openvpn {{path/to/client.conf}}
   
• Try to set up an insecure peer-to-peer tunnel on bob.example.com host:
   
  sudo openvpn --remote {{alice.example.com}} --dev {{tun1}} --ifconfig {{10.4.0.1}} {{10.4.0.2}}
   
• Connect to the awaiting bob.example.com host without encryption:
   
  sudo openvpn --remote {{bob.example.com}} --dev {{tun1}} --ifconfig {{10.4.0.2}} {{10.4.0.1}}
   
• Create a cryptographic key and save it to file:
   
  openvpn --genkey --secret {{path/to/key}}
   
• Try to set up a peer-to-peer tunnel on bob.example.com host with a static key:
   
  sudo openvpn --remote {{alice.example.com}} --dev {{tun1}} --ifconfig {{10.4.0.1}} {{10.4.0.2}} --secret {{path/to/key}}
   
• Connect to the awaiting bob.example.com host with the same static key as on bob.example.com:
   
  sudo openvpn --remote {{bob.example.com}} --dev {{tun1}} --ifconfig {{10.4.0.2}} {{10.4.0.1}} --secret {{path/to/key}}
