Help me with Access-Challenge configuration

[Stefan Winter]

Hi,

Alan's problem with this "simple" question of yours is that it's not
just simple, but simplistic. RADIUS can convey *many different*
authentication protocols which are all using an Access-Challenge to send
challenge data back. The content of the Access-Challenge, and the
configuration needed for that specific Access-Challenge, is
significantly different.

The fact that you ask the question like you did is a strong indication
that you don't know about this fact. Please ask a question like

How to configure freeRADIUS server so it replies with a CHAP "access-challenge" message on "access-request" from a client?
How to configure freeRADIUS server so it replies with a MS-CHAP "access-challenge" message on "access-request" from a client?
How to configure freeRADIUS server so it replies with a MS-CHAPv2 "access-challenge" message on "access-request" from a client?
How to configure freeRADIUS server so it replies with a EAP-TLS "access-challenge" message on "access-request" from a client?
How to configure freeRADIUS server so it replies with a EAP-TTLS "access-challenge" message on "access-request" from a client?
How to configure freeRADIUS server so it replies with a PEAP "access-challenge" message on "access-request" from a client?

See? You need to be more specific in your question before anyone here can give you an answer. Or better yet, read up on RADIUS, and/or EAP methods, and *then* ask a well-informed question.

Greetings,


Stefan Winter
