FreeRadius questions

28 Feb 2012

      Hope you can help us out.  First time dealing with RADIUS servers.  Following your instructions.  Seem to have missed something along the way.

We are running FreeRadius(Version 2.1.1) on a SLES version 11 server.  The serve has a static IP address.

We have tried both of the following setting in our client.conf file(/etc/raddb/clients.conf).  Neither have produced good results.

client localhost {
         ipadddr = 127.0.0.1
        require_message_authenticator = no
        secret = "xxxxx"
        nastype = "other"
}

client localhost {
         ipadddr = 10.0.xxx.xxx
        require_message_authenticator = no
        secret = "xxxxx"
        nastype = "other"
}

We entered a user in our user(/etc/raddb/users) file

bob     Cleartext-Password := "hello"

Started two terminal sessions.  In the first session we ran /usr/sbin/radiusd -X

And received these results

In the second terminal window we ran:

And got these results

Searched for solutions to this error message, but have not been able to find any that work.  Could you please tell us what we did wrong.
