Important: is is recommended to consider fail2ban utility alternative. Use denyhosts only if you really need it. Take a look on sa-box-bootstrap for example of usage.

One of the reasons: for example, in 14.04 LTS package is no longer maintained

apt-get install denyhosts

Apparently it has been deleted, according to launchpad.

DenyHosts is a python program that automatically blocks SSH attacks by adding entries to /etc/hosts.deny. DenyHosts might also inform Linux administrators about offending hosts, attacked users and suspicious logins.

Example of use: check box-example

Simple:

     - {
         role: "sa-denyhosts"
       }

Advanced:

my_whitelisted_boxes:
  - "sshd:	192.168.0.10"
  - "sshd:	192.168.0."
  - "sshd:	192.168.0.0/255.255.255.0"

     - {
         role: "sa-denyhosts",
         deploy_whitelisted_hosts: "{{my_whitelisted_boxes}}"
       }
