hi,

here's a port for https://reaction.ppom.me/, which is a lightweight
fail2ban-like, currently written in go (but uses few modules and builds
quickly) and pending a rewrite in rust (per
https://framagit.org/ppom/reaction/-/issues/103)

the configuration can be in jsonnet or yaml format (cf
https://blog.ppom.me/en-reaction/), i've included under files/ an
authlog.jsonnet sample that upstream provides to add ssh bots to a
blocked_ssh table, one only needs to append two lines to pf.conf to
block those (a MESSAGE files advises so).

feedback welcome!

Landry
