voyageur@gentoo.org Bernard Cafarelli reaction is a daemon that scans program outputs for repeated patterns and takes action, a common usage being to scan ssh and webserver logs and ban hosts that cause repeated authentication errors. It aims at being a faster and simpler successor to fail2ban, with configuration written in YAML or JSONnet.
