Generación de una nueva cuenta VPN

Dentro de srv-firewall (A.K.A. gorgoroth o firewall) nos introducimos en la carpeta de los ficheros de conf de OpenVPN.

$ cd /etc/openvpn/easy-rsa/2.0

Ejecutamos el script de generación de claves para el usuario:

$ source ./vars
$ ./build-key USUARIO*

* El usuario consiste en el primer caracter del identificador nombre seguido del apellido, (eje. Mikel Blanco ⇒ mblanco)

nos hará una serie de cuestiones que procederemos a contestar con lógica:

gorgoroth:/etc/openvpn/easy-rsa/2.0# ./build-key mblanco
