Tech Note - RADIUS Troubleshooting Version 0.9 Diagnostic Tools A great tool for testing basic IP connectivity and RADIUS availability on the amigopod is to download an open source RADIUS test client such as NTRadPing. This tool is available for download from Novell at the following URL: http://www.novell.com/coolsolutions/tools/14377.html The NTRadPing tool allows you to define a RADIUS destination IP Address, port number and a test user. This is incredibly useful for determining whether the RADIUS transactions are successfully making it to the amigopod or being blocked by VLAN configurations or firewall rules. See screenshot below of a successful authentication attempt from NTRadPing to the amigopod. In order to successfully authenticate to the amigopod you must define a NAS entry under the RADIUS Services Æ NAS List with the IP Address of your test computer. As with all RADIUS configurations the shared secret and 1812 must match on both the client and the amigopod. CONFIDENTIAL 3
