As far as i can remember, yes. nethserver-fail2ban configure some “contextual” jails due to modules of Nethserver, and as “a starter” can help a lot the establishment of not naked server for password guessing attacks.
Nevertheless, the sysadmin should review and validate the settings, and not trust the defaults. And NethServer is not for endusers, but for sysadmins, even not skilled/experieced.
@cronlabspl please, try to be nice and polite. Don’t avoid criticism and analysis, but also please don’t disrespect projects that are not interesting/safe for you and the mantainers.
Currently as concept I am not that fond of Crowdsec, I expressed why some posts ago on this topics. As bear, pizza or meat, it’s common for having different tastes, even not liking at all the plate/drink
Ok, maybe I’m not the best… expression for “playing it nice”
but anyway critics with reasons and explainations could lead any project to improvement.
