Testing cloud RADIUS connectivity

In this topic, you will learn what you can do to test the connectivity between your devices and Portnox™ Cloud RADIUS servers.

Recommended methods

Use third-party applications for RADIUS server testing. You can use any such application you like, the following are our recommendations:

Note: Use the correct IP, port, and secret value for the cloud RADIUS server, but if you just need to test network connectivity, you ignore other fields such as user credentials.
  • Windows: NTRadPing: free, GUI-based utility.

  • macOS: EAPTest: paid, GUI-based app.

  • Linux: FreeRADIUS: open-source, contains a command-line utility radtest.

  • Cross-platform: RadPerf: free, command-line utility with packages for several operating systems.

Unavailable methods

The following methods will not work:

  • ICMP Ping (Echo): Portnox cloud RADIUS servers are hosted in Microsoft Azure, and Microsoft does not allow ICMP Echo Request or Echo Rely packets in Azure. If you try to ping the RADIUS server, you will get no answer. For the same reason, ICMP-based traceroute command will not work, either.

  • UDP Echo: At the moment the Portnox cloud RADIUS servers do not respond to generic UDP requests, including UDP Echo. However, we are considering introducing this support in the future.
