A puppet module to manage the known_hosts files for users and the system.

Module Description

The module will manage the /etc/ssh/ssh_known_hosts and and users' ~/.ssh/known_hosts that you configure it for. It will purge any unmanaged entries from these files. This is different from the sshkey resource, which does not purge entries and only manages the system-wide known hosts.


What known_hosts affects

  • Entries in /etc/ssh/ssh_known_hosts (Purges unmanaged entries!)
  • Entries in ~/.ssh/known_hosts for a given user (Also purges unmanaged entries!)

Beginning with known_hosts

To purge all entries in the system's known_hosts:

include ::known_hosts

To purge a given user's known_hosts:

::known_hosts::user { 'user': }


At this point you can add back entries to the files. For system-wide:

::known_hosts::known_host { '':
  type => 'ssh-rsa',
  key  => 'key goes here',

Or, for a specific user:

::known_hosts::known_host { '':
  user => 'user',
  type => 'ssh-rsa',
  key  => 'key goes here',



Public classes

  • known_hosts: main class, sets up the system-wide known_hosts file

Defined types

  • known_hosts::user: sets up the known_hosts file for a user
  • known_hosts::known_host: adds an entry to the known_hosts file

Parameters: known_hosts::known_host

The following parameters are available to the known_hosts::known_host defined type.


Whether or not the entry should be present or not.


The user to add the entry for. If left undefined then the entry is added system-wide (default).


Whether the key should be marked as revoked or not. Default is not revoked.


Additional aliases for the host that use the same key. Should be an array aliases.


The type of key to define. Valid options are any valid key type. See man sshd for more information.


The actual key to include in the entry.


This module has been tested on:

  • Debian 8 (jessie)


This module is still under development. If you would like to help (especially for platforms other than Debian) please send fork the project at GitHub and send a pull request. New features belong in a feature branch named feature/your-feature and the pull request should be against the develop branch. Please add your name below and to the authors section of any file that you modify. While not required, it would be nice if you wrote test cases for any functionality that you add.
