It's primarily intended for preventing bruteforce attacks on authentification- protected services (SSH, telnet, etc). This module mainatins per-host statistics list. When the number of failed authentification attempts from one hosts exeeds pre-configured limit, the module performs special actions. The module was tested on FreeBSD 7.x/6.x/5.x/4.x. It's still in alpha quality, since it was not widely testes. However, it's used already in production, on 20+ servers ;-) Feel free to send comments/bug reports/suggestions to me. It'll be very helpful for me. Home page of the module: http://mbsd.msk.ru/pam_af.html. Thanks in advance, Stanislav Sedov.
