# ALCASAR is a Free and open source NAC (Network Access Controler) created by Franck BOUIJOUX (3abtux), Pascal LEVANT and Richard REY (Rexy)
# ALCASAR is based on a stripped Mageia (LSB) with the following open source softwares Coovachilli, freeradius, mariaDB, lighttpd, php, netfilter, e2guardian, ntpd, openssl, unbound, gammu, Ulog, fail2ban, vnstat, wkhtml2pdf, ipt_NETFLOW, NFsen and NFdump
# contact : info@alcasar.net
# Install script for ALCASAR (a secured and authenticated Internet access control captive portal)
# This script is distributed under the Gnu General Public License (GPLV3)
# Options :
# -i or --install
# -u or --uninstall
# Functions :
# system_testing : Free space test and mageia version test
# network_testing : Internet connectivity tests
# 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
# ulogd : Log system in userland (match NFLOG target of iptables)
# nfsen : Configuration of Netflow grapher (nfsen) & netflow collector (nfcapd)
# unbound : Name server configuration
# vnstat : Little network stat daemon
# BL : Adaptation of Toulouse University BlackList : split into 3 BL (for unbound, 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)
# msec : Mageia security package configuration
# letsencrypt : Let's Encrypt client
# mail_service : Mail service for email authentification method
# post_install : Security, log rotation, etc.
