EAP-SIM authentication failed
Hi guys, for my thesis i need to realize a EAP-SIM Authentication testbed. I'm using a Nokia E52 with EAP-SIM, a MIKROTIK router as access point and FreeRADIUS 2.1.10 as Radius server. I have added the necessary commands in the clients.conf, radiusd.conf, eap.conf and default files in order to enable EAP-SIM Authentication on the FreeRADIUS and I've created a flat file ' simtriplets.dat ' that is used from the Radius during the authentication process. By trying to access to the Wlan with the mobile phone (Nokia E52), i got the message that the authentication was unsuccessful. But by looking at the radius debug file, i cannot recognize any failure or messages like 'Access-Reject'. The debug file shows that radius got two ' Access-Request' packets from MIKROTIK router and it also sent two 'Access-Challenge' packets back to the router. It seems the radius is waiting for next requests and then the authentication process just ends up. so my questions are: -how many request packets are needed to complete the eap-sim authentication? -what should I configure to get more than 2 Access-Request here is the content of my debug file: . . .

Re: EAP-SIM authentication failed
Didn't you make another fix afterward regarding AT_IDENTITY (commit cfd61d24b99022eb613054bbf7e0da4fa3af1bde)? Not the patch from Microsoft. I know I have to patch the 2.2.0 source in our RPMs with this commit otherwise it fails ;) On 2012-11-06, at 10:15 AM, Alan DeKok wrote: > Phil Mayers wrote: >> Was that after 2.2.0 was released? > > No, before. > > Alan DeKok. > - > List info/subscribe/unsubscribe?

Re: EAP-SIM authentication failed
I have the same problem with Nokia E51 handset. EAP-SIM authentication interrupted by Nokia supplicant. Unfortunately there is no useful diagnostic on the handset. On other hand EAP-SIM authentication succeeds when I use wpa_supplicant on Windows using smart card reader with the same SIM card I've used with Nokia handset. Unfortunately I have neither iPhone nor Windows-based handset to test EAP-SIM against. Yann R.

RE: EAP-SIM authentication failed
Hi guys, i'm still looking for a solution for the eapsim authentication. Now i use the Freeradius 3.0.0 and i made some changes in the 'eapsimlib.c' regarding AT_IDENTITY (commit cfd61d24b99022eb613054bbf7e0da4fa3af1bde). I still have the same problem, the client is able to send two Acces-Request but unable to send the third Access-Request to close the authentication. I use a Nokia E52 as supplicant, did anybody realize the test successfully with another mobile phone (except android phones)? Does anyone know how i can debug the mobile phone? any helpfull ideas? here my debug radiusd: FreeRADIUS Version 3.0.0 (git #d3c7336), for host i586-pc-linux-gnu, built on Nov 7 2012 at 14:54:31 . .

RE: EAP-SIM authentication failed
Hi guys, i'm still trying to authenticate a EAP SIM Client with the Freeraduis 3.0.0. By Using the Nokia E51 and E52, the eap-sim authentication process just stops after the raduis has sent the " EAP-REQUEST, SIM-CHALLENGE" (containing AT_RAND and AT_MAC) message (see log info.). I did some changes in the in the " eapsimlib.c" regarding the AT_IDENTITY by using the patch 'commit cfd61d24b99022eb613054bbf7e0da4fa3af1bde' but the result didn't change. I decided to change the Client. I downloaded and installed Xsupplicant 2.2.3.553 on my windows XP. This is a software capable to be used as EAP-SIM Client. I didn't change anything on the server side. This time Xsupplicant replys with a " EAP-RESPONSE, SIM-CHALLENGE" (containing AT_MAC) after recieving the " EAP-REQUEST, SIM-CHALLENGE" (containing AT_RAND and AT_MAC). The Freeradius Server recieves the " EAP-RESPONSE, SIM-CHALLENGE" (containing AT_MAC), says that the received MAC doesn't match and breaks the authentication process with a "access reject" Here the log messages with Nokia: Listening on authentication address * port 1812 Listening on accounting address * port 1813 Listening on command file /var/run/radiusd/radiusd.sock Listening on authentication address 127.0.0.1 port 18120 as server inner-tunnel Opening new proxy address * port 1814 Listening on proxy address * port 1814 Ready to process requests. rad_recv: Access-Request packet from host 192.168.10.212 port 48077, id=19, length=308 Service-Type = Framed-User Framed-MTU = 1400 User-Name = "19017...@wlan.mnc070.mcc901.3gppnetwork.org" NAS-Port-Id = "ap_hotspot" NAS-Port-Type = Wireless-802.11 Acct-Session-Id = "8253" Acct-Multi-Session-Id = "00-0C-42-64-41-9D-A8-7E-33-3E-9C-5B-82-50-00-00-00-00-00-03" Calling-Station-Id = "A8-7E-33-3E-9C-5B" Called-Station-Id = "00-0C-42-64-41-9D:YANN" EAP-Message = 0x02010038013139303137303030303030303036353340776c616e2e6d6e633037302e6d63633930312e336770706e6574776f726b2e6f7267 Message-Authenticator = 0x429b263e5293fadbae0a13f28dad2775 NAS-Identifier = "MT_Yann" NAS-IP-Address = 192.168.10.212 (0) # Executing section authorize from file /usr/local/etc/raddb/sites-enabled/default (0) group authorize { (0) - entering group authorize {...} (0) [preprocess] = ok (0) [chap] = noop (0) auth_log : expand: %{Packet-Src-IP-Address} -> 192.168.10.212 (0) auth_log : expand: /var/log/radiusd/radacct/%{%{Packet-Src-IP-Address}:-%{Packet-Src-IPv6-Address}}/auth-detail-%Y%m%d -> /var/log/radiusd/radacct/192.168.10.212/auth-detail-20121108 (0) auth_log : /var/log/radiusd/radacct/%{%{Packet-Src-IP-Address}:-%{Packet-Src-IPv6-Address}}/auth-detail-%Y%m%d expands to /var/log/radiusd/radacct/192.168.10.212/auth-detail-20121108 (0) auth_log : expand: %t -> Thu Nov 8 14:20:05 2012 (0) [auth_log] = ok (0) [mschap] = noop (0) [digest] = noop (0) suffix : Looking up realm "wlan.mnc070.mcc901.3gppnetwork.org" for User-Name = "19017...@wlan.mnc070.mcc901.3gppnetwork.org" (0) suffix : Found realm "~.*.3gppnetwork.org$" (0) suffix : Adding Stripped-User-Name = "19017653" (0) suffix : Adding Realm = "wlan.mnc070.mcc901.3gppnetwork.org" (0) suffix : Authentication realm is LOCAL.

It's probably a bug somewhere. Very likely, the wrong data is being fed into the MAC at both ends. Unfortunately, since FreeRADIUS works with *some* EAP-SIM/AKA supplicants, I am guessing there are incompatible implementations out there. You would need to read the SIM/AKA RFCs in detail, and possibly feed the test data into FreeRADIUS to find the bug. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
