Overview

This module installs, configures and manages the Fail2ban service.

Module Description

This module handles installing, configuring and running Fail2ban across a range of operating systems and distributions.

Setup

What fail2ban affects

fail2ban package.
fail2ban configuration file.
fail2ban service.

Setup Requirements

Puppet >= 3.0
Facter >= 1.6
Extlib module
Stdlib module

Beginning with fail2ban

Install and configure fail2ban:

    class { 'fail2ban': }

Config file template

You can also manually specify a different configuration template. To do it, use your desired configuration template (e.g. if your template is in your local profile):

  class { 'fail2ban':
    config_file_template => "profile/fail2ban/etc/fail2ban/jail.conf.epp"
  }

Or using Hiera:

fail2ban::config_file_template: "profile/fail2ban/etc/fail2ban/jail.conf.epp"

Usage

Update the fail2ban package.

    class { 'fail2ban':
      package_ensure => 'latest',
    }

Remove the fail2ban package.

    class { 'fail2ban':
      package_ensure => 'absent',
    }

Purge the fail2ban package (All configuration files will be removed).

    class { 'fail2ban':
      package_ensure => 'purged',
    }

Deploy the configuration files from source directory.

    class { 'fail2ban':
      config_dir_source => "puppet:///modules/profile/fail2ban/etc/fail2ban",
    }

Deploy the configuration files from source directory (Unmanaged configuration files will be removed).

    class { 'fail2ban':
      config_dir_purge  => true,
      config_dir_source => "puppet:///modules/profile/fail2ban/etc/fail2ban",
    }

Deploy the configuration file from source.

    class { 'fail2ban':
      config_file_source => "puppet:///modules/profile/fail2ban/etc/fail2ban/jail.conf",
    }

Deploy the configuration file from string.

    class { 'fail2ban':
      config_file_string => '# THIS FILE IS MANAGED BY PUPPET',
    }

Deploy the configuration file from template.

    class { 'fail2ban':
      config_file_template => "profile/fail2ban/etc/fail2ban/jail.conf.epp",
    }

Deploy the configuration file from custom template (Additional parameters can be defined).

    class { 'fail2ban':
      config_file_template     => "profile/fail2ban/etc/fail2ban/jail.conf.epp",
      config_file_options_hash => {
        'key' => 'value',
      },
    }

Deploy additional configuration files from source, string or template.

    class { 'fail2ban':
      config_file_hash => {
        'jail.2nd.conf' => {
          config_file_path   => '/etc/fail2ban/jail.2nd.conf',
          config_file_source => "puppet:///modules/profile/fail2ban/etc/fail2ban/jail.2nd.conf",
        },
        'jail.3rd.conf' => {
          config_file_path   => '/etc/fail2ban/jail.3rd.conf',
          config_file_string => '# THIS FILE IS MANAGED BY PUPPET',
        },
        'jail.4th.conf' => {
          config_file_path     => '/etc/fail2ban/jail.4th.conf',
          config_file_template => "profile/fail2ban/etc/fail2ban/jail.4th.conf.epp",
        },
      },
    }

Disable the fail2ban service.

    class { 'fail2ban':
      service_ensure => 'stopped',
    }

    'nginx-login':
      filter_failregex: '^<HOST> -.*POST /sessions HTTP/1\.." 200'
      action: 'iptables-multiport[name=NoLoginFailures, port="http,https"]'
      logpath: '/var/log/nginx*/*access*.log'
      maxretry: 6
      bantime: 600
