Bruteblock allows system administrators to block various bruteforce attacks on UNIX services. The program analyzes system logs and adds attackers' IP addresses into the ipfw2 table, effectively blocking them. Addresses are automatically removed from the table after specified amount of time.

Bruteblock doesn't use any external programs and works with ipfw2 tables via the raw sockets API.
