# 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, lighttpd, netfilter, e2guardian, 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
#	freeradius		: FreeRadius initialisation
#	chilli			: coovachilli initialisation (+authentication page)
#	e2guardian		: E2Guardian 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 e2guardian and for Netfilter)
#	cron			: Logs export + watchdog + connexion statistics
#	fail2ban		: Fail2ban IDS installation and configuration
#	gammu_smsd		: Autoregister addon via SMS (gammu-smsd)
