Description
Bruteblock allows system administrators to block various bruteforce attacks on UNIX services. The program analyzes system logs and adds attacker's IP address into ipfw2 table effectively blocking them. Addresses are automatically removed from the table after specified amount of time. Bruteblock uses regular expressions to parse logs, which provides flexibility allowing it to be used with almost any network service. Bruteblock is written in pure C, doesn't use any external programs and work with ipfw2 tables via raw sockets API.

Message after installing
Configuration of the bruteblock is done via configuration files
located at /usr/local/etc/bruteblock.
To run the script, append following lines to /etc/syslog.conf:
!*
auth.info;authpriv.info |exec /usr/local/sbin/bruteblock -f /usr/local/etc/bruteblock/ssh.conf
and restart syslogd.
Also you should add ipfw2 table and the corresponding deny rule.
For example,
ipfw add deny ip from table(1) to any
Next, you'll want to setup periodical cleanup of ipfw2 table.
Add following lines to /etc/rc.conf:
bruteblockd_enable="YES"
bruteblockd_table="1"
bruteblockd_flags="-s 5"
and start bruteblockd:
