bruteforceblocker is a script that checks sshd's auth.log for Failed
login attemtps and cooperates with pf firewall. When given IP gains
specific number of fails, bruteforceblocker adds this IP to the pf's
table. This is useful for people who are getting large number of
these attempts.

Fix:

XBruteForceBlocker is a script, that works along with pf - OpenBSD's firewall.
XWhen this script is running, it checks sshd's auth log for Failed Password
Xattempts and counts it's number. When given IP reaches specified number of
Xfails, script adds this IP to the pf's table and block any other traffic to
Xthe given box. If you are bored of those automated auth tries, you will be
Xhappy with this script. It also includes a simple rc script.
