# 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, havp, libclamav, Ulog, fail2ban, 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
#	init_db			: Initilization of radius database managed with MariaDB
#	radius			: FreeRadius initialisation
#	radius_web		: copy ans modifiy original "freeradius web" in ACC
#	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 du grapheur nfsen pour apache 
#	dnsmasq			: Name server configuration
