Re: [Serusers] Authorization Problems with Radius.

The log error below does not say why authentication failed. I would recommend you to use some sniffer to see if the radiusclient library sends any packets to the server.

Here is the list of common problems:

1) the hostname of the radius server is not configured properly in radiusclient.conf (authserver) 2) The shared secret is not configured properly, the shared secret dictionary is by default in /usr/local/etc/radiusclient/servers 3) The shared secret is not configured properly in the server 4) radius server is missing SIP related attributes.

In my radiusclient.cfg i have configured for authentication localhost:1645. In my Radius Server (Radiator) i'm not see any Radius message.

What is the problem? Hope someone can help me

Thank in advance BEst Regards
