How-to: Test forward and reverse DNS resolution of an host name
Overview
Three steps are needed to configure the plugin to work:
- Define resource which defines access to the plugin.
- Define test cases in Pineapple module.
This example extends the last step of the basic example by adding some new test cases.
For information about how to define resource, credentials and modules refer to the plugin usage page.
A prefabricated example in the default configuration
Pineapple includes a prefabricated version of this example in the default configuration. The example is named infrastructure-test-003-dns-resolution-localhost. The default configuration is created by starting Pineapple. The default configuration will also create the required resource in the local environment which is used to execute the test operation on the model.
Add forward and reverse DNS resolution test cases to Pineapple module
Open the model file for the target environment and add the test case:
<?xml version="1.0" encoding="UTF-8"?>
<mmd:models xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mmd="http://pineapple.dev.java.net/ns/module_model_1_0"
xmlns:ifp="http://pineapple.dev.java.net/ns/plugin/infrastructure_1_0" >
<mmd:model target-resource="infrastructure-test">
<mmd:content>
<itp:infrastructure>
<itp:dns-resolution-test host="garuda" ip="10.20.30.1" description="host garuda resolves to IP 10.20.30.1 and back" />
</itp:infrastructure>
</mmd:content>
</mmd:model>
</mmd:models>
Meaning of the elements in the test
- The dns-resolution-test element defines the skeleton of the test case.
- The description attribute should contain a suitable description of the test which is used by Pineapple at run time in clients and reports to show the outcome of the test.
- The host attribute defines the host name which should be resolved to an IP address and resolved in reverse from the IP address.
- The ip attribute defines the IP address which should be resolved from a host name and resolved back to the host name.
