Thank you very much Ivan for your detailed response. I will check it and respond you. Regards, Dhandapani Ivan Kalik wrote:
Not sure how ssh/telnet will handle.
That depends on your pam radius module. I believe freeradius hosted module can handle it. Don't know for others.
But I assume, other than password it may request for additional RSA key generated to access a particular machine or something similar to that.
Why? Server already knows it's RSA key. This has nothing to do with user authentication.
Also, does NAS need any installation to support Access-Challenge like CHAP?
It needs pam module that supports it. BTW chap doesn't have Access-Challenge in the authentication process. Nor mschap.
