ENCIENDE EQUIPOS

================

CONTENIDO:

EnciendeEquipos.py: Programa principal. Realiza consulta anonima a LDAP, obteniendo las MAC's de los equipos que quieren encenderse. Utiliza dos filtros

distintos para realizar la consulta: uno se refiere a los equipos del diurno y otro a los del nocturno, podeis modificarlos a vuestro antojo e incluir los

equipos que querais. La consulta para obtener las MAC'S la hace en la rama host del LDAP. Debeis modificar la IP que hace referencia al ldap, en la linea

l = LdapConnection ("172.23.36.5"), y poner la de vuestro LDAP.

NetworkUtils.py: Contiene funcion para el encendido de un equipo, a partir de su mac. Esta funcion ha sido programada por J.L. Redrejo.

LdapConnection.py: Utilidades para conectar y buscar en LDAP.

INSTRUCCIONES DE USO:

Copiar carpeta EnciendeEquipos en /usr/bin del servidor. Modificar crontab para que se lance en el momento del dia que nos interese:

20 8 * * 1-5 root /usr/bin/python /usr/bin/EnciendeEquipos/EnciendeEquipos.py (para el dia)
