Overview

Module to manage OpenSSH with focus on using augeas for configfile modifications to provide compatibility with upstream changes in this files.

Puppetversion: >= 3.5.0

OS: RedHat, Debian

Module Description

This Module installs the openssh server and client and manages the sshd_config. It optionally gathers the hostkeys and provides them for other hosts.

Setup

What openssh affects

  • Packages and service for openssh
  • sshd_config
  • system-wide known_hosts file

Setup Requirements

To use spreading of hostkeys you will need a puppetdb-enabled puppetserver

Beginning with openssh

To begin using this module with default parameters, declare the class with include openssh

Any Puppet code that uses anything from the apt module requires that the core apt class be declared.

Usage

Simple usage

Install packages, set some defaults, ensure service is running, export all keys to all hosts

class { 'openssh': }

Advanced usage

Because the hash of the config-parameter gets passed comletely to augeas, you can use all options your augeas lens provides in the way your augeas lens specifies it. Here are some examples for that:

Install packages, set some custom values, ensure service is running, export and collect no keys

class { '::openssh':
  config => {
    'X11Forwarding'      => 'no',
    'AllowTcpForwarding' => 'yes',
    'Port'               => '222',
  },
  exporttag  => false,
  collecttag => false,
}

Even more advanced usage

Install packages, set two listening ports and special parameters for group "no-admin", ensure service is running, export keys with tag "customer_hosts" and collect no keys

class { '::openssh':
  config => {
    'X11Forwarding' => 'no',
    'AllowTcpForwarding' => 'yes',
    'Port[1]'            => '222',
    'Port[2]'            => '333',
    'Match[1]/Condition/Group'          => 'no-admin',
    'Match[1]/Settings/ChrootDirectory' => '/home',
    'Match[1]/Settings/X11Forwarding'   => 'no',
  },
  exporttag  => 'customer_hosts',
  collecttag => false,
}

Reference

Classes

  • openssh: Main class that is used to set the variables and includes the other classes

  • openssh::params: Sets defaults for the variables used by this module

  • openssh::install: Installs the packages on the system

  • openssh::config: Cares about the whole openssh-configuration including rollout of known hostkeys

  • openssh::service: Handles the openssh service

Parameters

openssh

  • ensure: Set the ensure-value for the packages. Default: 'present'

  • packages: Name or array of the packages to be installed. Default: osfamily-specific (see params.pp)

  • servicename: Name of the service to be started Default: osfamily-specific (see params.pp)

  • sshd_config: Path to the sshd_config file Default: /etc/ssh/sshd_config

  • sshd_config_def: Default values for sshd_config parameters. This should almost never need to be changed.

  • config: A hash with all options that should get set in sshd_config

  • exporttag: Tag that the exported hostkey get for collecting. If 'false', key won't get exported. Default: managedhosts

  • collecttag: Keys with this tag will get collected. If 'false', keys won't get collected.
