Kedar, I have used response becoz, I will be sending a EAP-Identity reponse packet to the Radius Server. So the code field is not Request it should be Response. All, Thanks for the help. I was able send the EAP message with EAP-Type-Identity field. I have got an Access-Challenge response from the server, and the Access-Request sent in response to this challenge is failing (Access-Reject is sent by the server). Below i have given the debug log from the server, -------------------------------------------------------------------------------------------------------------------------------- rad_recv: Access-Request packet from host 127.0.0.1:32825, id=60, length=113 User-Name = "jrc" User-Password = "jrc" NAS-Identifier = "jrcnas" NAS-Port-Type = Ethernet CUI = "0" Service-Type = Framed-User Framed-MTU = 1400 Calling-Station-Id = "1:1:1:1:1:1" Message-Authenticator = 0xaff453c7f7e3dc3639458de9740366a1 EAP-Message = 0x02d20008016a7263 Processing the authorize section of radiusd.conf modcall: entering group authorize for request 1 modcall[authorize]: module "preprocess" returns ok for request 1 modcall[authorize]: module "chap" returns noop for request 1 modcall[authorize]: module "mschap" returns noop for request 1 rlm_realm: No '@' in User-Name = "jrc", looking up realm NULL rlm_realm: No such realm "NULL" modcall[authorize]: module "suffix" returns noop for request 1 rlm_eap: EAP packet type response id 210 length 8 rlm_eap: No EAP Start, assuming it's an on-going EAP conversation modcall[authorize]: module "eap" returns updated for request 1 users: Matched entry DEFAULT at line 152 users: Matched entry jrc at line 179 modcall[authorize]: module "files" returns ok for request 1 modcall: leaving group authorize (returns updated) for request 1 rad_check_password: Found Auth-Type EAP auth: type "EAP" Processing the authenticate section of radiusd.conf modcall: entering group authenticate for request 1 rlm_eap: EAP Identity rlm_eap: processing type md5 rlm_eap_md5: Issuing Challenge modcall[authenticate]: module "eap" returns handled for request 1 modcall: leaving group authenticate (returns handled) for request 1 Sending Access-Challenge of id 60 to 127.0.0.1 port 32825 CUI = "jrccui" Class = 0x6a7263636c617373 State = 0x6a72637374617465 Framed-MTU = 1400 Framed-IP-Address = 1.2.3.4 Service-Type = Framed-User Session-Timeout = 30 MS-MPPE-Send-Key = 0x6a72636d736b MS-MPPE-Recv-Key = 0x6a7263726563766d736b AAA-Session-Id = "jrcmultisessionid" HA-IP-MIP4 = 1.1.1.1 DHCPv4-Server = 2.2.2.2 MN-HA-MIP4-KEY = "jrcmipkey" MN-HA-MIP4-SPI = "jrcmipspi" DHCP-RK = "jrcdhcprk" DHCP-RK-KEY-ID = "jrcdhcpkey" DHCP-RK-LIFETIME = "20" EAP-Message = 0x01d300160410e0ccb378852f7a673815379d2f819db1 Message-Authenticator = 0x00000000000000000000000000000000 State = 0x8343fbb52835fa0fb7fb84cab7f7a0db Finished request 1 Going to the next request --- Walking the entire request list --- Waking up in 6 seconds... rad_recv: Access-Request packet from host 127.0.0.1:32825, id=61, length=155 User-Name = "jrc" User-Password = "jrc" NAS-Identifier = "jrcnas" NAS-Port-Type = Ethernet CUI = "0" Service-Type = Framed-User Framed-MTU = 1400 Calling-Station-Id = "1:1:1:1:1:1" Message-Authenticator = 0x8dc52d59961b5eb7d8789f7cb4dbea5a State = 0x6a72637374617465 State = 0x8343fbb52835fa0fb7fb84cab7f7a0db EAP-Message = 0x02d300160410d3ab9cde585da0c10b343d38433fa0db Processing the authorize section of radiusd.conf modcall: entering group authorize for request 2 modcall[authorize]: module "preprocess" returns ok for request 2 modcall[authorize]: module "chap" returns noop for request 2 modcall[authorize]: module "mschap" returns noop for request 2 rlm_realm: No '@' in User-Name = "jrc", looking up realm NULL rlm_realm: No such realm "NULL" modcall[authorize]: module "suffix" returns noop for request 2 rlm_eap: EAP packet type response id 211 length 22 rlm_eap: No EAP Start, assuming it's an on-going EAP conversation modcall[authorize]: module "eap" returns updated for request 2 users: Matched entry DEFAULT at line 152 users: Matched entry jrc at line 179 modcall[authorize]: module "files" returns ok for request 2 modcall: leaving group authorize (returns updated) for request 2 rad_check_password: Found Auth-Type EAP auth: type "EAP" Processing the authenticate section of radiusd.conf modcall: entering group authenticate for request 2 rlm_eap: Either EAP-request timed out OR EAP-response to an unknown EAP-request rlm_eap: Failed in handler modcall[authenticate]: module "eap" returns invalid for request 2 modcall: leaving group authenticate (returns invalid) for request 2 auth: Failed to validate the user.

Why is the Code field of the EAP message 01? Isn't that a REQUEST message? Please correct me if I am wrong, but I thought the RADIUS server should get a Response packet with Code 2 and Type should be 1 (EAP Resp/Identity packet). May be it didnt get the Identity packet, and hence it cannot verify the Identity.

I changed it but the same error is still coming.

You have misconfigured the Nas-Identifier
govardhana Nas-Identifier == nas, Nas-Port-Type == 15
You have NAS-Identifier = "jrcnas"

Hi,
I was trying to configure FreeRadius server with EAP authentication. AS mentioned in "eap.conf", I didn't change the Auth-Type, but I was sending a EAP message, and Message-Authenticator attributes in Access-Request. When i tried sending an Access-Request with EAP-Message, I got the following error "rlm_eap: Identity Unknown, authentication failed".
How to configure the Identity for EAP?
