Proceso realizado sobre la plataforma de Linux Ubuntu ® 10.04
- Descargamos el programa Freeradius desde la página
La version mas actual es la 2.1.8
- Insatalamos de acuerdo a las instrucciones que se encuentran en la carpeta del archivo descargado, utilizando las opciones de make y make install
- Al intentar coorer el progrma con radiusd -X aparecia un error en el cual decia que algunas librerias no exitían
- Despues de revisar algunos tutoriales no dimos cuentas que neceitabamos unos archivos antes de correr el programa
- Intalamos las siguientes librerias:
- apt-get intall gcc
- apt-get intall build-essential
- apt-get intall libssl-dev
- apt-get intall libpq-dev - Cuando utilzamos en la terminal radiusd -X nos aparecia la respuesta “Ready to process request”, sin embargo primero debiamos configura los archivos necesarios
- Despues de algunas configuraciones en el router, en el cliente y en el servidor seguiamos sin establecer conexion, aunque cuando se manda se mandaba una peticion desde el cliente hacia el servidor este la pasaba por alto.
Domingo 30 de mayo, 2010
- Despues de leer algunos foros y tutoriales hemos logrado que el servidor ya no ignore la peticion del cliente aunque sin establecer una conexion
- La respuesta del promt es:

Luego de varios intentos "fallidos" (realmente no fueron fallidos ya que aprendimos mucho acerca de ello)de establecer una conexión con nuestro servidor Radius bajo Ubuntu , y realizando previamente varias consultas a persona que pudieron asesorarnos bajo propias experiencias , decidimos cambiar de distribución hacia una que prestaba mucho más factibilidad y soporte para realizar este procedimiento ,es decir que decidimos empezar nuevamente el proceso en Linux CentOS 5.4 ® , aunque ya no de cero ya que se tenía varios conocimientos de lo que se iría a realizar .
- Descargamos el iso del internet (CentOS 5.4).
- Se instaló el sistema en una máquina virtual.
Martes 8 de junio del 2010
- Con el sistema ya instalado , se procedió a repartir la ardua tarea de investigar acerca de el modo de implementar este servidor en este sistema Operativo.
- Encontrada cierta información muy valiosa , se inició el proceso de instalación de free radius en este sistema .
- Se buscó los certificados a instaarse en cada configuración(tanto del cliente en windows como del servidoren Linux).
- Se encontró en su totalidad todos estos certificados , y aunque ansiosos de continuar , ya era muy tarde y tuvimos que aplazarlo para una muy proxima oportunidad de continuar con la misma.
Sabado 12 de junio del 2010
- Se modificó los archivos de configuración tal como se conocía que era necesario (users,clients.conf,radiusd.conf y eap.conf ubicados en la ruta /etc/raddb), pues se investigó en varias fuentes andes de realizarlo ya que son documentos muy extensos en los que hay que realizar la operaciones lo más precisamente posible , pues se puede modificar un sector no necesario involuntariamente y toda la configuración y funcionamiento podría venirse abajo.
- Se copiaron también los certificados en la ruta /etc/raddb para sustituirlos por los ya existentes , tal como se sabía por todas las consultas realizadas.
- Se realizó practicamente a la par la configuración de l router a usarse ,ya uqe este debía encontrarse en sincronía completa con el servidor radius para que la conexión se lle ve a cabo.
- Se necesitaba una máquina con una conexión inalámbrica con un sistema operativo Windows Vista ó 7 ya que los certificados que se encontraron eran diseñados para estas versiones de OS.
- Conseguida la máquina , se pudo instalar estos certificados .
- Se consultó ampliamente acerca de las configuraciones de la estación de trabajo ó cliente para su correcta configuración y funcionamiento en la red controladad por este servidor radius.
- Se aplicaron estas configuraciones en el cliente .
- Finalmente se estableció una conexión con el servidor radius de modo adecuado .
- Se realizó el videotutorial de acuerdo a las especificaciones acordadas en clase
