# 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 Mageia 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 Mageia (LSB) with the following open source softwares :
#
# Coovachilli, freeradius, mariaDB, apache, netfilter, squid, dansguardian, ntpd, openssl, dnsmasq, havp, libclamav, Ulog, fail2ban, NFsen and NFdump
# Options :
# -i or --install
# -u or --uninstall
# Functions :
# testing : connectivity tests and downloading before intall
# init : Installation of RPM and scripts
# network : Network parameters
# ACC : ALCASAR Control Center installation
# CA : Certification Authority initialization
# init_db : Initilization of radius database managed with MariaDB
# param_radius : FreeRadius initialisation
# param_web_radius : copy ans modifiy original "freeradius web" in ACC
# param_chilli : coovachilli initialisation (+authentication page)
# param_squid : Squid cache proxy configuration
# param_dansguardian : DansGuardian filtering HTTP proxy configuration
# antivirus : HAVP + libclamav configuration
# param_nfsen : Configuration du grapheur nfsen pour apache
# dnsmasq : Name server configuration
# BL : BlackList of Toulouse configuration : split into 3 BL (for Dnsmasq, for dansguardian and for Netfilter)
# cron : Logs export + watchdog + connexion statistics
# fail2ban : Fail2ban installation and configuration
# post_install : Security, log rotation, etc.
