# 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, dansguardian, ntpd, openssl, dnsmasq, gammu, havp, libclamav, Ulog, fail2ban, tinyproxy, NFsen and NFdump
# Options :
# -i or --install
# -u or --uninstall
# Functions :
# testing : connectivity tests, free space test and mageia version test
# init : Installation of RPM and scripts
# network : Network parameters
# ACC : ALCASAR Control Center installation
# CA : Certification Authority initialization
# time_server : NTPd configuration
# init_db : Initilization of radius database managed with MariaDB
# radius : FreeRadius initialisation
# chilli : coovachilli initialisation (+authentication page)
# dansguardian : DansGuardian filtering HTTP proxy configuration
# antivirus : HAVP + libclamav configuration
# tinyproxy : little proxy for user filtered with "WL + antivirus" and "antivirus"
# ulogd : log system in userland (match NFLOG target of iptables)
# nfsen : : Configuration of Nfsen Netflow grapher
# dnsmasq : Name server configuration
# vnstat : little network stat daemon
# BL : Adaptation of Toulouse University BlackList : split into 3 BL (for Dnsmasq, for dansguardian and for Netfilter)
# cron : Logs export + watchdog + connexion statistics
# fail2ban : Fail2ban IDS installation and configuration
# gammu_smsd : Autoregister addon via SMS (gammu-smsd)
# msec : Mandriva security package configuration
# letsencrypt : Let's Encrypt client
# post_install : Security, log rotation, etc.
