Official site: http://www.example42.com

Official git repository: http://github.com/example42/puppet-openssh

Released under the terms of Apache 2 License.

For detailed info about the logic and usage patterns of Example42 modules read README.usage on Example42 main modules set.

USAGE - Basic management

  • Install openssh with default settings

    class { "openssh": }
    
  • Disable openssh service.

    class { "openssh":
      disable => true
    }
    
  • Disable openssh service at boot time, but don't stop if is running.

    class { "openssh":
      disableboot => true
    }
    
  • Remove openssh package

    class { "openssh":
      absent => true
    }
    
  • Enable auditing without without making changes on existing openssh configuration files

    class { "openssh":
      audit_only => true
    }
    

USAGE - Overrides and Customizations

  • Use custom sources for main config file

    class { "openssh":
      source => [ "puppet:///modules/lab42/openssh/openssh.conf-${hostname}" , "puppet:///modules/lab42/openssh/openssh.conf" ], 
    }
    
  • Use custom source directory for the whole configuration dir

    class { "openssh":
      source_dir       => "puppet:///modules/lab42/openssh/conf/",
      source_dir_purge => false, # Set to true to purge any existing file not present in $source_dir
    }
    
  • Use custom template for main config file

    class { "openssh":
      template => "example42/openssh/openssh.conf.erb",      
    }
    
  • To manipulate options in your config using the options array you should use this syntax in your config UsePAM <%= scope.function_options_lookup(['UsePAM','no']) %> LogLevel <%= scope.function_options_lookup(['LogLevel','INFO']) %> ListenAddress <%= scope.function_options_lookup(['ListenAddress', '0.0.0.0']) %>

  • Define custom options that can be used in a custom template without the need to add parameters to the openssh class

      class { "openssh":
        template => "example42/openssh/openssh.conf.erb",    
        options  => {
          'LogLevel'      => 'INFO',
          'UsePAM'        => 'yes',
          'ListenAddress' => '0.0.0.0'
        },
      }
    
  • Automaticallly include a custom subclass

    class { "openssh:"
      my_class => 'openssh::example42',
    }
    

== USAGE - Manage a user SSH keys:

  • Use all defaults and place in the user's home directory ssh keys that are stored centrally on the puppet server.

      openssh::key { 'username': }
    

USAGE - Example42 extensions management

  • Activate puppi (recommended, but disabled by default) Note that this option requires the usage of Example42 puppi module

      class { "openssh": 
        puppi    => true,
      }
    
  • Activate puppi and use a custom puppi_helper template (to be provided separately with a puppi::helper define ) to customize the output of puppi commands

      class { "openssh":
        puppi        => true,
        puppi_helper => "myhelper", 
      }
    
  • Activate automatic monitoring (recommended, but disabled by default) This option requires the usage of Example42 monitor and relevant monitor tools modules

      class { "openssh":
        monitor      => true,
        monitor_tool => [ "nagios" , "monit" , "munin" ],
      }
    
  • Activate automatic firewalling This option requires the usage of Example42 firewall and relevant firewall tools modules

      class { "openssh":       
        firewall      => true,
        firewall_tool => "iptables",
        firewall_src  => "10.42.0.0/24",
        firewall_dst  => "$ipaddress_eth0",
      }
