Thanks Ivan for the clarification. I am just setting up the tool eapol_test to test it. Thanks. But I am also investigating whether it is possible to achieve Access Challenge with ssh/telnet without using any other tools. Could you please help if you have done it before? And also may I know why it is not advised to support Access Challenge for ssh or telnet. Regards, Dhandapani Ivan Kalik wrote:
I am trying to authorize the ssh and telnet login users of my Redhat Linux machine using freeRadius server.
I am able to test Access-Accept and Access-Reject with right and wrong credentials respectively by configuring the file '/etc/pam.d/sshd' with entry pam_radius_auth.so.
But I do not know how to achieve and test the Access-Challenge concept.
Do you need to? ssh and telnet supplicants tend not to use protocols with challenge-response exchange.
I mean what type of input will result in Access Challenge (I know it happens when we provide partial login information but not sure how to achieve with login in real time)?
Send an eap request (eapol_test).
