Hello, - I will look into that book you recommended Alan - "OReilly book on OpenSSLL" thanks! - But for right now do you have any clues on what I could/do test, look at to fix this: - I have a Linux client trying to connect to the Free Radius, and on the client side I am getting this error message: "CTRL-EVENT-EAP-FAILURE EAP authentication failed" - And on the Free radius console I have this information is shown: Called-Station-Id = "00-20-a6-64-c3-b1:MVG-Personal" Calling-Station-Id = "00-0f-cb-f9-3b-f9;MVG-Personal" NAS-Identifier = "MVG-1" State = 0x73e4f46973e6f0393091c54faaf880fd Framed-MTU = 1400 NAS-Port-Type = Wireless-802.11 EAP-Message = 0x020200060315 Message-Authenticator = 0x330b306447495e1a49cd5c7cfe5c1c6d +- entering group authorize ++[preprocess] returns ok ++[chap] returns noop ++[mschap] returns noop rlm_realm: No '@' in User-Name = "easy", looking up realm NULL rlm_realm: No such realm "NULL" ++[suffix] returns noop rlm_eap: EAP packet type response id 2 length 6 rlm_eap: No EAP Start, assuming it's an on-going EAP conversation ++[eap] returns updated ++[unix] returns notfound users: Matched entry easy at line 90 expand: Hello, %{User-Name} -> Hello, easy ++[files] returns ok ++[expiration] returns noop ++[logintime] returns noop rlm_pap: Found existing Auth-Type, not changing it. ++[pap] returns noop rad_check_password: Found Auth-Type EAP auth: type "EAP" +- entering group authenticate rlm_eap: Request found, released from the list rlm_eap: EAP NAK rlm_eap: EAP-NAK asked for EAP-Type/ttls rlm_eap: processing type tls rlm_eap_tls: Initiate rlm_eap_tls: Start returned 1 ++[eap] returns handled Reply-Message = "Hello, easy" EAP-Message = 0x010300061520 Message-Authenticator = 0x00000000000000000000000000000000 State = 0x73e4f46972e7e1393091c54faaf880fd Finished request 1. Going to the next request Waking up in 4.9 seconds. Cleaning up request 0 ID 153 with timestamp +279 Cleaning up request 1 ID 154 with timestamp +279 Ready to process requests. - And the client don't get/receive an IP address, guessing it has something to do with EAP authentication "No EAP Start". Thanks for help, Best regards, Johan Nyman
