SSHBlock is a Perl script that works with hosts.deny to block brute force attempts to log in to ssh.

Functionality

SSHBlock is a daemon to monitor a syslog log for break-in attempts using SSH, and to automatically block bad hosts by adding lines to /etc/hosts.allow (TCP Wrappers). Several thresholds are pre-defined, to be able to block those trying many attempts within a longer or shorter period. Use -h to see command line options.
