# This script is distributed under the Gnu General Public License (GPL)
# Script d'installation d'ALCASAR (Application Libre pour le Contrôle d'Accès Sécurisé et Authentifié au Réseau)
# ALCASAR est architecturé autour d'une distribution Linux Mandriva minimaliste et les logiciels libres suivants :
# Install script for ALCASAR (a secured and authenticated Internet access control captive portal)
# ALCASAR is based on a stripped Mandriva (LSB) with the following open source softwares :
#
# Coovachilli (a fork of chillispot), freeradius, mysql, apache, netfilter, squid, dansguardian, awstat, ntpd, openssl, dnsmasq, havp, libclamav and firewalleyes
# Options :
# -i or --install
# -u or --uninstall
# Functions :
# testing : Tests de connectivité et de téléchargement avant installation
# init : Installation des RPM et des scripts
# network : Paramètrage du réseau
# gestion : Installation de l'interface de gestion
# AC : Initialisation de l'autorité de certification. Création des certificats
# init_db : Création de la base 'radius' sur le serveur MySql
# param_radius : Configuration du serveur d'authentification FreeRadius
# param_web_radius: Configuration de l'interface de gestion de FreeRadius (dialupadmin)
# param_chilli : Configuration du daemon 'coova-chilli' et de la page d'authentification
# param_squid : Configuration du proxy squid en mode 'cache'
# param_dansguardian : Configuration de l'analyseur de contenu DansGuardian
# antivirus : Installation havp + libclamav
# param_awstats : Configuration de l'interface des statistiques de consultation WEB
# dnsmasq : Configuration du serveur de noms et du serveur dhcp de secours
# BL : Configuration de la BlackList
# cron : Mise en place des exports de logs (+ chiffrement)
# post_install : Finalisation environnement ( sécurité, bannières, rotation logs, ...)
