Radiator Cookbook

This cookbook strives to be a simple way of handling the installation of Radiator and it's dependencies on different platforms. Radiator is an AAA server for RADIUS, TACACS+ and Diameter from Radiator Software. Radiator is a commercial product and has a separate commercial license. You can find more information in the License and Authors section below.

As Radiator is not available publicly you will need to have a wrapper cookbook or some other way of delivering the installation file to the server you are using this cookbook on.

The configuration of Radiator is pretty flexible and there are several use cases. It is not in the scope of this cookbook to support each and every available parameter of the Radiator configuration. Thus, the configuration provided by the example attributes and template are very simple.

These example attributes serve as a starting point. Much like the goodies in the Radiator installation itself, more examples will be added later. See the example attributes section below for more information.

You can override the template with your own in a wrapper cookbook to achieve a configuration suitable for your business logic.

Development of this cookbook started when the version of Radiator was 4.16. You can probably use this to install older Radiators, but it is not supported.

Installation assumes internet connectivity for the dependency installation. If you have any limitations in your environment, you can install the needed packages yourself in a wrapper cookbook for example.

Requirements

Attributes

The attributes used by this cookbook are under the radiator name space. Default values are set in attributes/default.rb. An example configuration is available in attributes/example.rb.

This cookbook is meant to be used with the provided resources, but you can control some aspects via attributes.

Radiator installation attributes:

node['radiator']['user']: The user to install, configure and run Radiator for. This is a string. Defaults to radiator.
node['radiator']['group']: The group to install, configure and run Radiator for. This is a string.Defaults to radiator.
node['radiator']['user_home']: The home directory for the service user. This is a string.Defaults to /home/radiator.
node['radiator']['user_shell']: The shell for the service user. This is a string. Defaults to /bin/false.

Additional pack installation attributes:

Currently supported are Radiator SIM Pack, Radiator Carrier Pack, Radiator Telco Pack and Radiator GBA/BSF Pack.

node['radiator']['supported_packs']: The packs supported by this cookbook. You should not have the need to change this. This is an array. Defaults to ['sim', 'telco', 'carrier', 'gba-bsf'].
node['radiator']['install_packs']: Similar to the above. A list of packs to be installed with the radiator_installation resource. You can also control the list with the property of the resource itself. This list exists as an attribute mostly for the use of the dependencies recipe. This is an array. Defaults to [].

Evaluation attributes:

node['radiator']['evaluation']['install_version']: The version of Radiator to be installed with the evaluation recipe. This is a string. Defaults to 4.21.
node['radiator']['evaluation']['download_username']: The username to be used when downloading the evaluation version with the evaluation recipe. This is a string. You will have to contact support for your username.
node['radiator']['evaluation']['download_password']: The password to be used when downloading the evaluation version with the evaluation recipe. This is a string. You will have to contact support for your password.
node['radiator']['evaluation']['show_license']: Whether to print the Radiator license when installing with the evaluation recipe. This is a true or false value. Defaults to true.
node['radiator']['evaluation']['accept_license']: Whether to accept the Radiator license when installing with the evaluation recipe. This is a true or false value. Defaults to false. You will need to change this to true, to get the installation to work.

Example configuration attributes:

These attributes are set in the attributes/example.rb and are used in the radiator:etc/radiator/example.cfg.erb template to create a simple configuration.

See the template file itself for more details on how these are used.

default['radiator']['configuration']['Trace'] = 2
default['radiator']['configuration']['AuthPort'] = 1812
default['radiator']['configuration']['AcctPort'] = 1813
default['radiator']['configuration']['LogDir'] = '/var/log/radiator'
default['radiator']['configuration']['Log']['FILE']['Identifier'] = 'radiator-log'
default['radiator']['configuration']['Log']['FILE']['Trace'] = 2
default['radiator']['configuration']['Log']['FILE']['Filename'] = '%L/radiator.log'
default['radiator']['configuration']['Client'] = {
  'DEFAULT' => {
    'Secret' => 'chef',
    'Identifier' => 'chef'
  }
}

Recipes

default

This is a dummy recipe.

dependencies

The dependencies recipe handles the installation of any dependency modules, either from the distribution repositories or CPAN. If you select this recipe in your run_list, either directly or by using the evaluation recipe, you accept the fact that modules are installed from CPAN and software for building packages, like gcc and make, will be installed.

evaluation

This recipe will use the evaluation attribute described above to download the spesified version of Radiator for evaluation purposes. You will need to accept the license by setting the node['radiator']['evaluation']['accept_license'] attribute to true before this will work.

More details can be found in the evaluation section below.

Resources

radiator_installation

The radiator_installation resource is divided into a few providers, namely archive and package. The providers naturally do things a bit differently, but the goal is to install Radiator, and the packs, from either an archive format (usually .tgz) or a package (deb or rpm).

Actions

create: This handles installation and is the default.
remove: This handles uninstallation.

Properties

version: Spesifies the version of Radiator to be installed. Can be a string or nil. Defaults to the name of the resource.
user: The service user to be created and which the install uses. Can be a string or a false value. Defaults to node['radiator']['user'].
group: The service group to be created and which the install uses. Can only be a string. If user is false, this won't be used. Defaults to node['radiator']['group'].
user_home: The home directory for the service user to be created. Can only be a string. If user is false, this won't be used. Defaults to node['radiator']['user_home'].
user_shell: The shell for the service user. Can only be a string. If user is false, this won't be used. Defaults to node['radiator']['user_shell'].
install_options: The installation options to be passed on as properties to the resources handling the installation. This can be used to control the options of the yum_package and apt_package resources for example. A more detailed example below. Defaults to: {}.
packs: The extra packs to be installed. The options are similar to the parent radiator_installation resource, which means that you can pass install_options to individual pack installs for example. A more detailed example below. This is a Poise library option_collector, so you can pass a hash or a block-like syntax. Defaults to {}.

Examples

Install Radiator from an archive:

radiator_installation 'example-archive-install' do
  provider 'archive'

  version '4.21'

  install_options do
    path 'https://example.com/downloads/Radiator-4.21.tgz'
  end
end

radiator_installation '4.21' do
  provider 'archive'

  install_options do
    path 'https://example.com/downloads/Radiator-4.21.tgz'
  end
end

node.default['my_wrapper_cookbook']['radiator']['version'] = '4.21'
node.default['my_wrapper_cookbook']['radiator']['path'] = 'https://example.com/downloads/Radiator-4.21.tgz'

radiator_installation 'example-archive-install-from-attributes' do
  provider 'archive'

  install_options node['my_wrapper_cookbook']['radiator']
end

Install Radiator from a package:

radiator_installation 'example-package-install' do
  provider 'package'

  version '4.21'
end

radiator_installation '4.21' do
  provider 'package'

  install_options do
    source 'https://example.com/downloads/Radiator-4.21.rpm'
  end
end

radiator_installation 'example-install-of-any-version-with-packs-from-repository' do
  provider 'package'

  version nil

  packs %w(sim carrier)
end

radiator_installation 'example-upgrade-of-radiator' do
  provider 'package'

  version nil

  install_options do
    action :upgrade
  end
end

node.default['my_wrapper_cookbook']['radiator']['sim']['install_options']['version'] = '2.3'
node.default['my_wrapper_cookbook']['radiator']['sim']['install_options']['source'] = 'https://example.com/downloads/Radiator-EAP-SIM-2.3.rpm'

radiator_installation 'example-package-install-with-packs' do
  provider 'package'

  version '4.2.0'

  packs(
    sim: node['my_wrapper_cookbook']['radiator']['sim']
  )
end

Some more examples can be found in the test directories spec/unit/libraries and test/fixtures/cookbooks/test/recipes.

radiator_configuration

The radiator_configuration resource is renders the configuration file of Radiator from a template. It also supports a config_verify option to make sure the radiusd -c config check passes before putting the new configuration file in to use. The resource provides a config_path method you can use to grab the full path of the configuration file for use in other resources.

Actions

config_template: The template to be used as the source for rendering the configuration file. Can only be a string. A source cookbook can be supplied by providing the cookbook and file with the syntax: <cookbook>:<template. If the cookbook is not provided, the file is expected to be found in the calling cookbook. Defaults to: etc/radiator/example.cfg.erb.
config_variables: Variables to be pushed to the rendered template. Can only be a hash. Defaults to: {}.
config_helpers: Helper methods or modules to be pushed to the rendered template. Can only be an array. Defaults to: []. The methods in Radiator::Helpers::Configuration module are always included.

config_verify: Whether to run radiusd config check during the render. Can be a true or false value. Defaults to: true.
config_sensitive: Whether to pass the sensitive property to the rendered template. Can be a true or false value. Use this if you have passwords in the configuration that you want to hide from Chef logging. Defaults to: false.

Examples

Create a radius.cfg configuration file:

radiator_configuration 'radius' do
  config_template 'my_wrapper_cookbook:my_templates/raw-radiator-config.cfg.erb'
end

node.default['my_wrapper_cookbook']['radiator']['configuration']['Trace'] = 4

radiator_configuration 'example-configuration' do
  config_file 'radius.cfg'

  config_variables(
    config: node['my_wrapper_cookbook']['radiator']['configuration'],
    example: true,
  )
end

Some more examples can be found in the test directories spec/unit/libraries and test/fixtures/cookbooks/test/recipes.

radiator_service

The radiator_service resource creates service startup files and can be used to start, stop and reload the service. It supports starting multiple instances of the same service with systemd instantiated units with the instances property. The resources is based on the Poise ServiceMixin, so things that apply there, apply here too.

perl_bin: Perl binary to be used for starting radiusd. Can only be a string. Defaults to: /usr/bin/env perl.
radiusd_bin: Location of the radiusd executable. Can only be a string. Defaults to finding the correct path depending on the used radiator_installation resource.
instances: Instances of the service to start with systemd. Can be an integer or array. Integer is the number of instances, array is used for the names of the instances. The name of the instance is passed on to the running Radiator with the instance global var. Defaults to: 0.
args: Any extra arguments to pass to radiusd. Can only be an array. Defaults to: [].
modules: Any extra modules to load with Perl. Can only be an array. These are prepended with -M. Defaults to: [].
dictionaries: Radiator dictionary files to pass to radiusd. Can only be an array. Defaults to: ['/etc/radiator/dictionary'].
vars: Any extra global vars to pass to radiusd. Can only be a hash. Defaults to: {}.
environment: Any extra environment variables to provide for the service. Can only be a hash. Defaults to: {}.
restart_mode: Restart mode in case of a systemd service. Can only be a string. Defaults to: always.
overrides: Any systemd unit file overrides to create. Can be a string or a hash. The syntax is the same as Chef's systemd_unit resource. Defaults to: ''.

Examples

Run Radiator with a radius.cfg configuration file:

radiator_service 'radius'

radiator_service 'radiator' do
  config_path '/etc/radiator/radius.cfg'
end

radiator_service 'radiator' do
  instances 4

  config_path '/etc/radiator/radius.cfg'
end

radiator_service 'radiator' do
  instances ['one', 'two', 'three', 'four']

  config_path '/etc/radiator/radius.cfg'
end

Override some options for systemd and provide extra stuff for Radiator:

radiator_service 'radiator' do
  config_path '/etc/radiator/my-exotic-configuration.cfg'
  directory '/home/radiator'

  modules ['Something::Special']
  args ['-trace 4']
  vars(
    my_variable: 'hello'
  )

  environment SOME_VARIABLE: 'hello world'

  restart_mode 'on-failure'
  overrides(
    Unit: {
      Documentation: 'https://www.open.com.au/radiator/ref.pdf',
    }
  )
end

Some more examples can be found in the test directories spec/unit/libraries and test/fixtures/cookbooks/test/recipes.

Evaluation

If you have access to Radiator evaluation, you can use this cookbook to download the evaluation version and run it using Vagrant. For more information about Radiator evaluation and licensing, see https://radiatorsoftware.com/evaluation/

The included Vagrantfile installs and configures a Linux box and uses this cookbook to setup Radiator. Two distributions are supported currently, Ubuntu 16.04 and CentOS 7.4. The boxes used are provided by the Bento project.

The Radiator evaluation archive is automatically downloaded with your credentials. It is also set to automatically accept the license. By starting the Vagrant box, you agree to the Radiator Standard End User License Agreement.

Instructions:

Install Vagrant.
- The default provider is Virtualbox.
Install ChefDK.
- This is required for the Berkshelf integration plugin and working with Chef cookbooks and recipes.
Install Vagrant Berkshelf plugin.
- Command: vagrant plugin install vagrant-berkshelf
- This is required for handling cookbook dependencies in the Vagrant machine.
Add your credentials for downloading the evaluation version in an environment variable:
- Command: export RADIATOR_EVAL_USERNAME=username
- Command: export RADIATOR_EVAL_PASSWORD=password
Start the evaluation Vagrant box.
- Command: vagrant up radiator-ubuntu or vagrant up radiator-centos.
- By default the Ubuntu box is used.
Wait for the Vagrant box to start. UDP ports 1812 and 1813 for authentication and accounting are forwarded and you can start testing.
- You can login with the command: vagrant ssh.
- If you have radpwtst at hand, you can test a RADIUS packet with the command: radpwtst -auth_port 1812 -s localhost -noacct -secret evaluation.

It is also possible to instantiate the evaluation box with Test Kitchen. More details below.

Testing

The cookbook has unit tests in the form of Chefspec specs. You can find them in the spec directory. InSpec profiles are provided along with .kitchen.ymlconfiguration for Test Kitchen. The profiles are in the test/smoke directory.

In addition the style is checked with Cookstyle and Foodcritic.

You can run the tests like so:

Style checks:

chef exec cookstyle
chef exec foodcritic --rule-file .foodcritic .

Unit testing:

chef exec rspec

Smoke testing:

This will converge all different platforms and Chef versions
- kitchen test

Converging an evaluation machine:

Ubuntu 16.04 with Chef 13.8.5
- kitchen converge evaluation-ubuntu-1604-1385
CentOS 7.4 with latest Chef'
- kitchen converge evaluation-centos-74-latest
