Installing CrowdSec agent and firewall bouncerįirst, install CrowdSec repositories. We are very community-driven in this area. If you wish to have other bouncers ported to Raspberry PI OS please let us know. So far only the firewall bouncers for iptables and nftables are available. In this example, I’m using Raspberry Pi OS v11.3 on Raspberry Pi 4. So if you run into any problems please let us know. Theoretically, they should work on all versions of Raspberry Pi but this hasn’t been tested yet. One of the biggest changes in CrowdSec from v1.3.0 has happened behind the scenes as we now produce precompiled binaries for arm and Raspberry Pi OS. Raspberry Pi is a perfect device for this as it’s a cheap way to help out collecting CTI - while hopefully annoying criminals who are lured into wasting time in our ssh tarpit. In this article, I’ll describe how to install the CrowdSec agent and the firewall bouncer directly on Raspberry Pi OS and convert it into a sort of honeypot using endlessh (an ssh tarpit) and a web server which only purpose is for CrowdSec to detect attacks in its logfiles.
