This gem provides Ruby bindings to the S2 NetBox API for S2 Security Systems products.

This Gem has been written pretty specifically for the needs of Teamsquare's internal management systems.

Through S2Netbox::ApiRequest class you should be able to invoke any API command on the S2 controller by hand, however only the specific ones we're using have been built out and tested.

The specific methods we're using have been documented under the Usage section. See the section "Other Commands" for details on how to invoke any arbitrary command in addition to the list of "supported" commands below.

Add this line to your application's Gemfile:

gem 's2_netbox'

And then execute:

$ bundle

Or install it yourself as:

$ gem install s2_netbox

A call to S2Netbox.configure must be made before API requests can be made. This sets up the controller's base URL as well as the username and password used when logging in.

S2Netbox.configure do |config|
    config.controller_url = 'https://controller-host'
    config.username = 'api'
    config.password  = '[W2tnwoUdE+/97o8nmi#P77t'
end

If you're using the S2Netbox gem in a Rails app, this could be placed in an initializer.

All requests are bundled up into the required XML parcel with the required COMMAND and PARAMS.

Once sent to the configured S2 controller, the response is wrapped up in an instance of S2Netbox::Response which includes the following accessors:

• code
• success
• details
• error_message
• raw_request
• raw_response
• session_id

code returns the raw code response which is typically either SUCCESS or FAIL, but sometimes has weird other alternatives, such as DUPLICATE or NOT FOUND just to keep things interesting.

success is a boolean indicating if the code was SUCCESS. Any other value for code results in success being false.

details is a hash of the returned details. For example, when getting a Person object, this will contain the person's attributes, such as FIRSTNAME and LASTNAME as well as a hash of ACCESSLEVELS. The details hash is keyed off the raw names of the XML attributes in the response (uppercase names, as a string, not symbol) so access them like:

@result.details['FIRSTNAME']

not

@result.details[:first_name]

error_message is populated with the error message returned from the system assuming code is not SUCCESS.

The raw_request and raw_response store the contents of the HTTP Post request and response respectively, so you can troubleshoot exactly what XML was sent and received by the systems.

session_id contains the value of the session_id attribute if it exists on the root <NETBOX> element in the raw_response. This is only populated in response to the Login command. Use this when parsing the result of a Login attempt and store the session_id for future requests.

The gem supports authentication by username and password only. Although you can configure it to use the sha_password method of authentication, at present the MAC signature is not generated or included with any request.

If your S2 system requires authentication via the sha_password and MAC signing, feel free to open a pull request :) Our systems are partitioned and don't use this form of authentication, but we'd love to accept a pull request to add this fucntionaltiy for other users.

Login is used to establish a session and obtain a session_id which is used in subsequent requests:

      @result = S2Netbox::Commands::Authentication.login

To get an instance of S2Netbox::Response which (assuming log in is successful) will include the session_id which can be used in subsequent requests:

    @result.session_id

All sessions must be logged out. According to the S2 documentation:

WARNING: Failure to match every call to ‘Login’ with a call to ‘Logout’ will result in the accumulation of session files, consuming potentially large amounts of disk space.

To log out, issue the logout command:

@result = S2Netbox::Commands::Authentication.logout('session_id_from_login')

The Version module allows you to query the current API version. This is really just an easy way to validate you're successfully connected to the S2 Controller and have a valid session.

@result = S2Netbox::Commands::ApiVersion.get_version('session_id_from_login')

The result object will contain the version (assuming you've successfully logged in):

:001 > puts @result.details['APIVERSION']
4.1

The Person module allows you to add and modify Person records.

The add_person method accepts 3 arguments:

1. Hash of person attributes
2. List of access levels
3. List of User Defined Fields
4. (Optional) session_id

@result = S2Netbox::Commands::Person.add({
    :person_id => '8a806ed6-0246-49d0-b7a7-ab6402da01e3',
    :first_name => 'John',
    :last_name => 'Appleseed',
    :exp_date => nil,
    :act_date => '10/10/2016'
    }, %w(AccessLevel1 AccessLevel2), 'UDF1'
)

Both access levels and user defined fields can be specified either as a single string or as an array of strings.

The modify_person method allows you to modify an existing person, and is similar to the add_person method, but has an additional argument:

1. Person ID
2. Hash of person attributes
3. List of access levels
4. List of User Defined Fields
5. (Optional) session_id

@result = S2Netbox::Commands::Person.modify('8a806ed6-0246-49d0-b7a7-ab6402da01e3', {
    :first_name => 'John',
    :last_name => 'Appleseed',
    :exp_date => nil,
    :act_date => '10/10/2016'
}, %w(AccessLevel1 AccessLevel2), 'UDF1')

Access levels and user defined fields are replaced with those values specified in this call, and aren't additive to existing access levels or user defined fields.

The add method accepts 2 arguments:

1. Hash of credential attributes
2. (Optional) session_id

@result = S2Netbox::Commands::Credential.add({
    :person_id => '8a806ed6-0246-49d0-b7a7-ab6402da01e3',
    :encoded_num => '3113',
    :card_format => '26 bit Wiegand'
})

This will add a 26 bit Wiegand encoded card with card number 3113 to the Person record identified by ID 8a806ed6-0246-49d0-b7a7-ab6402da01e3 in the S2 controller.

The modify method accepts 2 arguments:

1. Hash of credential attributes
2. (Optional) session_id

@result = S2Netbox::Commands::Credential.add({
    :encoded_num => '3113',
    :disabled => 1
})

This example will set disabled to 1 (a truthy value) for the credential identified with the ENCODEDNUM of 3113 in the S2 Controller.

By using the S2Netbox::ApiRequest class directly, you can send any command to the S2 Controller.

The send_request method allows commands to be sent to the S2 Controller and accepts the following arguments:

1. The command name
2. A hash of the command attributes
3. (Optional) session_id

For instance, although untested, you should be able to set a lockdown level by sending the command:

S2Netbox::ApiRequest.send_request('SetThreatLevel', {:level_group_name => 'Elevated'})

Will set the current threat level to the threat level with a name of Elevated in the S2 Controller.

The S2Netbox::ApiRequest.send_request method sends requests to the /goforms/nbapi endpoint.

For finer grained control and advanced requests, including the ability to change this path, you can call the lower level S2Netbox.request method.

The S2Netbox::request method takes three arguments:

1. Url
2. Command
3. (Optional) session_id

The url argument is the path to the API endpoint, such as /goforms/nbapi.

The command argument is the raw XML command that will be placed within the <NETBOX-API> element.

Pass in the optional session_id if you’re using username and password based authentication.
