#-------------------------------------------------------|
# 0/ Quick MISP Instance on Debian Based Linux - Status |
#-------------------------------------------------------|
#
#    20200513: Ubuntu 20.04 tested and working. -- sCl
#    20200412: Ubuntu 18.04.4 tested and working. -- sCl
#    20190302: Ubuntu 18.04.2 tested and working. -- sCl
#    20190208: Kali Linux tested and working. -- sCl
#
#
#-------------------------------------------------------------------------------------------------|
# 1/ For other Debian based Linux distributions, download script and run as **unprivileged** user |
#-------------------------------------------------------------------------------------------------|
#
# The following installs only MISP Core:
# $ wget --no-cache -O /tmp/INSTALL.sh https://raw.githubusercontent.com/MISP/MISP/2.4/INSTALL/INSTALL.sh ; bash /tmp/INSTALL.sh -c
#
# This will install MISP Core and misp-modules
# $ wget --no-cache -O /tmp/INSTALL.sh https://raw.githubusercontent.com/MISP/MISP/2.4/INSTALL/INSTALL.sh ; bash /tmp/INSTALL.sh -c -M
#
#
#-------------------------------------------------------|
# 2/ For Kali, download and run Installer Script        |
#-------------------------------------------------------|
#
# To install MISP on Kali copy paste the following to your shell:
# # wget --no-cache -O /tmp/misp-kali.sh https://raw.githubusercontent.com/MISP/MISP/2.4/INSTALL/INSTALL.sh && bash /tmp/misp-kali.sh
# NO other version then 2020.x supported, kthxbai.
# /!\ Please read the installer script before randomly doing the above.
# The script is tested on a plain vanilla Kali Linux Boot CD and installs quite a few dependencies.
#
#
#----------------------------------------------------------|
# 3/ The following script has been partially autogenerated |
#----------------------------------------------------------|
#
# To generate this script yourself, the following steps need to be taken.
# $ git clone https://github.com/SteveClement/xsnippet.git
# Make sure xsnippet resides somewhere in your $PATH - It is a shell script so a simple, copy to somewhere sane is enough.
# $ git clone https://github.com/MISP/MISP.git
# $ cd MISP/INSTALL ; ./INSTALL.tpl.sh
#
##
###
####----------------\
##   Developer Note |
####--------------------------------------------------------------------------------------------------|
##   In theory the order does not matter as everything is a self-contained function.                  |
#    That said, ideally leave the order as is and do NOT change the lines as they are place-holders.  |
#    Script files that do NOT have a #_name.sh are scripts that have NO functions. This is by design. |
