paso 1 : instalar Openvas
para instalar openvas podemos bajar el taz.gz directo del sitio oficial o ayudarnos de algún repositorio oficial reconocido por el sitio, en nuestro caso lo instalaremos via repositorio, ya que en mi persepcion los paquetes deben tener 1 sola forma de administrarse, en el caso que no exista algún repositorio oficial recomiendo nosotros mismos construir nuesto rpm, el cual no es el objetivo de este manual.
Instalamos la PGP del sitio autorizado.
# rpm --import http://www.atomicrocketturtle.com/RPM-GPG-KEY.art.txt
instalamos los archivos del deposito .
# lynx -source http://www.atomicorp.com/installers/atomic.sh | sh

openvassd has a rules system which allows you to restrict the hosts that enduser has the right to test.
For instance, you may want him to be able to scan his own host only.
Please see the openvas-adduser(8) man page for the rules syntax.
Enter the rules for this user, and hit ctrl-D once you are done:
(the user can have an empty rules set)
Login : enduser
Password : ***********
Rules :
Is that ok? (y/n) [y] y
user added.
