puppet-ssh

Overview

Install, enable and configure ssh and sshd. Currently supports RHEL6 and RHEL7 (and their rebuilds).

• ssh::service : Class to manage the sshd service.
• ssh::sshd_config : Class to manage the main sshd_config file.

The configuration changes made by this module are meant to be defined from hiera, in order to make specific overrides very easy. They are also meant to be minimal against the original files, in order to be trivial to review, as sshd is a really critical service.

The ssh::service class is included from ssh::sshd_config and really only exists in order to have configuration changes reload the service.

Examples

Disable password authentication and X11 forwarding globally, and permit root login only from some specific IP addresses :

---
classes:
  - '::ssh::sshd_config'
ssh::sshd_config::permitrootlogin: 'no'
ssh::sshd_config::passwordauthentication: 'no'
ssh::sshd_config::x11forwarding: 'no'
ssh::sshd_config::match:
  'Address 203.0.113.17,192.168.113.17,2001:db8:1:a211::1':
    'PermitRootLogin': 'yes'

Configure IdM authorized keys through SSSD :

---
classes:
  - '::ssh::sshd_config'
ssh::sshd_config::authorizedkeyscommand: '/usr/bin/sss_ssh_authorizedkeys'
ssh::sshd_config::authorizedkeyscommanduser: 'nobody'
