MI-LXC : Mini-Internet using LXC

MI-LXC uses LXC to simulate a small-scale internet-like environment. I use this environment for (infosec) practical work (intrusion, firewall, IDS, etc.). The small memory footprint of LXC combined with differential images allows to run it on modest hardware.

It is based on the infrastructure-as-code principle: these scripts programmatically generate the target environment.

Example practical work using this environment (in french) :
