Ask:
at openbsd we have pf

here I can block faulty logins in ssh
alone only with pf
board means


for freebsd i use ipfw v2

here I use fail2ban

Is there a way
not to use this fail2ban
i want to get away from python shit.

good would only use ipfw v2 without other software
 
What about built-in blacklistd(8) ?
I did not used it, so I can't provide additional details.
But blacklistd should to communicate with sshd and firewall like ipfw.
Blacklistd is a part of base FreeBSD system since FreeBSD 11.

For securing ssh on my hosts I prefer to have a ipfw table with a whitelist of trusted networks and hosts,
or to use only key-based authorization with completely disabled password-based authorization.
