Preventing SSH Dictionary Attacks With DenyHosts

From the tutorial: 
 “In this HowTo I will show how to install and configure DenyHosts. DenyHosts is a tool that observes login attempts to SSH , and if it finds failed login attempts again and again from the same IP address, DenyHosts blocks further login attempts from that IP address by putting it into /etc/hosts.deny. DenyHosts can be run by cron or as a daemon. In this tutorial I will run DenyHosts as a daemon.”
