Hello: Are there any clients that actually display the EAP-GTC challenge? Essentially, I am trying to use EAP-GTC similarly to how PAP Access-Challenge works: Client: -------User/Pass---------------->Server Client: <--Challenge Message---------Server Client: -------Challenge Response--->Server Client: <-------Accept------------------>Server So far, I cannot seem to find documentation to suggest that I CANNOT do this, and the spec suggests that I can, but I cannot seem to find anything that will do this. In addition, are there any resources that thoroughly documents EAP-GTC? The RFCs do not provide much information. Regards.

No idea. Try it and see.

The RFCs are the canonical source of information about EAP-GTC. There really isn't much else. Alan DeKok.
Hi,
Are there any clients that actually display the EAP-GTC challenge? Essentially, I am trying to use EAP-GTC similarly to how PAP Access-Challenge works:
have you tried wpa_supplicant or eapol_test ?
In addition, are there any resources that thoroughly documents EAP-GTC? The RFCs do not provide much information.
the RFC *is* the documentation for the EAP-GTC protocol ;-) alan
Hi Carl, I personally have used EAP-TTLS/EAP-GTC with Nokia S60 phone. Nokia S60 supplicant display EAP-GTC prompt. This prompt is set in raddb/eap.conf gtc{} subsection and defaults to "Password: " string. EAP-GTC is thoroughly documented by RFC 3748. Typical EAP-GTC message exchange is following: S: EAP-Request(Type=Identity) C: EAP-Response(Type=Identity, Type-Data=<username>) S: EAP-Request(Type=GTC, Type-Data=<prompt>) C: EAP-Response(Type=GTC, Type-Data=<password>) S: EAP-Success or EAP-Failure Carl Pierre wrote:
