6.4 Diagnostic Commands

6.4.1 Network Connectivity Verification#

To verify connectivity to the Guardpot appliance after network configuration changes (see Section 3.1.3), perform a ping test from an external machine:

A successful ping reply confirms that the hostname resolves to the correct IP address. The web interface login page, as shown in Figure 1.3.1-1, confirms full accessibility.

6.4.2 DNS Resolution Verification#

After configuring DNS records or hosts file entries (see Section 3.2.4), verify that name resolution is working correctly using the ping commands described in Section 6.4.1.

6.4.3 IP Address Conflict Check#

Before assigning a static IP address during installation (see Section 1.2.3), it is strongly recommended to verify that the selected IP address is not currently in use and will not cause network conflicts by performing a ping test or consulting your system administrator.

6.4.4 Secure Link Testing#

The Secure Link module (see Section 2.4) provides automated link validation between Guardpot instances. To manually verify connectivity:

• Navigate to the Link Checks view (see Section 2.4.3).

• Click Add New Link Checker to create a new test.

• Configure the source and target agents, target ports, and schedule.

• Click Save Scenario to activate the link check.

• Monitor the Last Status column in the List view (see Section 2.4.4) for test results.

6.4.5 Load Testing for Infrastructure Resilience#

The Load Tester module (see Section 2.8) performs bandwidth and stress tests against specified targets. To execute a diagnostic load test:

• Click the New Load Test button.

• In Step 1, select the source Guardpot agent.

• In Step 2, configure the test parameters:
