hi, i hope someone can help me to understand this case. from a nas cisco 1841 i send by pppoe a request to a freeradius Version 1.1.3. the response ever is NAS-Port=0 -- rad_recv: Accounting-Request packet from host xxxxxxxxxx:1646, id=114, length=168 Acct-Session-Id = "0C0C0C1400000071" Framed-Protocol = PPP Framed-Route = "xxxxxxxx 255.255.255.0" Framed-IP-Address = xxxxxxxxx User-Name = "xxxxxx" Acct-Session-Time = 177 Acct-Input-Octets = 10056 Acct-Output-Octets = 9579 Acct-Input-Packets = 147 Acct-Output-Packets = 125 Acct-Authentic = RADIUS Acct-Status-Type = Interim-Update NAS-Port-Type = Virtual NAS-Port = 0 NAS-Port-Id = "0/0/1/130" Service-Type = Framed-User NAS-IP-Address = xxxxxxx Acct-Delay-Time = 0 when i try it from a cisco pix to same freeradius, the answer is different rad_recv: Access-Request packet from host xxxxxxx:1025, id=157, length=123 User-Name = "xxxxxx" User-Password = "xxxxxxxx" NAS-IP-Address = 10.x.x.254 NAS-Port = 157 NAS-Port-Type = Virtual Cisco-AVPair = "ip:source-ip=10.x.x.x" Calling-Station-Id = "ip:source-ip=10.x.x.x" both cisco, 1841 and pix authenticate in the same freeradius why? how i can configurate the cisco 1841 to receive the information of the nas-port and Calling-Station-Id ? thanks. -- rad_recv: Accounting-Request packet from host xxxxxxxxxx:1646, id=114, length=168 Acct-Session-Id = "0C0C0C1400000071" Framed-Protocol = PPP Framed-Route = "xxxxxxxx 255.255.255.0" Framed-IP-Address = xxxxxxxxx User-Name = "xxxxxx" Acct-Session-Time = 177 Acct-Input-Octets = 10056 Acct-Output-Octets = 9579 Acct-Input-Packets = 147 Acct-Output-Packets = 125 Acct-Authentic = RADIUS Acct-Status-Type = Interim-Update NAS-Port-Type = Virtual NAS-Port = 0 NAS-Port-Id = "0/0/1/130" Service-Type = Framed-User NAS-IP-Address = xxxxxxx Acct-Delay-Time = 0 when i try it from a cisco pix to same freeradius, the answer is different rad_recv: Access-Request packet from host xxxxxxx:1025, id=157, length=123 User-Name = "xxxxxx" User-Password = "xxxxxxxx" NAS-IP-Address = 10.x.x.254 NAS-Port = 157 NAS-Port-Type = Virtual Cisco-AVPair = "ip:source-ip=10.x.x.x" Calling-Station-Id = "ip:source-ip=10.x.x.x" both cisco, 1841 and pix authenticate in the same freeradius why? how i can configurate the cisco 1841 to receive the information of the nas-port and Calling-Station-Id ? thanks. -

timeout if mysql backend not reachable
by PENZ Robert 09 Sep '10

09 Sep '10

Hi! I've more than one radius server configured on my switches. If one server timeouts the switch takes the second server. On each radius server a freeradius and a mysql db is running. I'm now searching for a way that the freeradius does not return anything (=timeout for the switch) if he cannot reach its mysql db (on the same machine). Currently I get a reject reply for the authentication request. How can I configure that? Thx! Mit freundlichen Grüßen Robert Penz ---------------------------------------------------- Dipl. Inf.

Upgrade to v2.1.9 - ntdomain logon issues
by Extra Fu 08 Sep '10

08 Sep '10

Hello, We've recently upgraded FreeRADIUS from v1.1.8 to v2.1.9. We use it together with Cisco AP to do WPA2 Enterprise using PEAP. All users and machines accounts are stored in LDAP (OpenLDAP) and Samba v3.0 is being used to provide a NT domain to Windows users. OpenLDAP contains the ntPassword and lmPassword attributes for all users and machines. Prior the update, everything was working fine - that is: Windows machine authentication (after it boots), standalone logon and domain logon. After the update to v2.1.9, the domain login now fails constantly (Windows machine authentication and standalone logon work as expected). When domain logon fails, we keep seeing in the logs "[eap] Identity does not match User-Name, setting from EAP Identity.". We do not do any User-Name rewrite. With tried with and without with_ntdomain_hack in the mschap module, with and without the inner-tunnel. We also tried to define a realm with the "nostrip" option w/o success. Any insights would be appreciated. Here is our FreeRADIUS configuration followed by the Accept-Request we get which fails during domain logon : radiusd -fX FreeRADIUS Version 2.1.9, for host i686-redhat-linux-gnu, built on Sep 1 2010 at 17:25:13 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.

RE: freeradius authentication stops working after some time...

I was wondering if anybody had any more information with this topic. Winbind authentication works every time during testing of ntlm_auth, but PEAP will only work once after a reboot and then fails every time. I can see a difference in the EAP-Message when running in debug mode once it gets Request 3's Access-Request packet. >> When Successful: rad_recv: Access-Request packet from host 172.20.1.99 port 65288, id=212, length=522 User-Name = " MYDOMAIN\\myuser" NAS-Port = 68 State = 0xbdba4064bfb959ed871d7a760f4a6189 EAP-Message = 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 EAP-Message = 0x640caaf2df40538fd91c1da8c2189b89d9d59e66b40f816d14030100010116030100303628b50481fc50a51db0c5315a5898ada3f498ed9385706e9b165e322cdb655704b73380d527cfa1966359f43e23b54a Message-Authenticator = 0xe0435af614c2b43a52ab07911e607257 Acct-Session-Id = "8O2.1x8155007a0006d0e1" NAS-Port-Id = "ge-0/0/1.0" Calling-Station-Id = "00-21-86-a0-d5-b6" Called-Station-Id = "00-1f-12-35-a3-40" NAS-IP-Address = 172.20.1.99 NAS-Identifier = "CL-SW-SPARE-P48-1" NAS-Port-Type = Ethernet ....

I generated my server certificate from our internal Microsoft Certificate Authority and installed them on the server. I'm pretty sure everything is okay since my Windows 2007 computer authenticates every time if configured to use certificate authentication rather than PEAP. Also, if I use Microsoft IAS as my radius server PEAP works every time, therefore I don't believe my network equipment is having any problems. Any additional ideas would be greatly appreciated. Thanks, Nick

Enabling Session Resumption in FreeRadius
by Panagiotis Georgopoulos 08 Sep '10

08 Sep '10

Hello all, I have a client that uses EAP-TTLS to authenticate to a FreeRadius (2.1.8) over different access networks. After some handovers from one network to another, I see in my FR log that session resumption fails, and specifically I see : Debug: SSL Connection Established Debug: SSL Application Data Info: [ttls] eaptls_process returned 3 Info: [ttls] Skipping Phase2 due to session resumption Info: [ttls] FAIL: *Forcibly stopping session resumption as it is not allowed* Info: [eap] Freeing handler Info: ++[eap] returns reject Info: Using Post-Auth-Type Reject Then a full EAP-TTLS exchange follows from the beginning that succeeds. However, the failure message above "Forcibly stopping session resumption as it is not allowed" implies that there is somewhere in the FR a setting that will allow it? Am I assuming rightly? If yes, where is this setting? If no, does anyone know why session resumption fails ? Thanks a lot in advance, Panos

Fwd: ldap group lookup help
by Walter Gould 08 Sep '10

08 Sep '10

I never saw a reply to my below e-mail. Would anybody have any thoughts or ideas on why our ldap group lookups fail after some period of time...? If it would help to send debug output, I can... Just for my information, are many folks out there using ldap/AD group lookups on large FR installs? Thanks in advance, Walter -------- Original Message -------- Subject: ldap group lookup help Date: Thu, 02 Sep 2010 09:49:02 -0500 From: Walter Gould <gouldwp(a)auburn.edu> To: FreeRadius users mailing list <freeradius-users(a)lists.freeradius.org> Group, We are having problems with ldap group lookups... Here's our environment. Using Freeradius 2.1.8 to authenticate wireless users against our AD servers and perform ldap group membership lookups. Using WPA2-AES-PEAP-MSCHAPv2. When radiusd is started, initially the lookups work fine and we see successful auth's in our radius logs. But, after some period of time, we eventually begin to see bunches of "Invalid user:" radius logs. The only thing that seems to fix this is to remove the ldap group lookups from the freeradius config. In our ldap module, the basedn we specify is dc=auburn,dc=edu (as we have multiple user ou's). Not sure if that might be causing an issue or not..? One thing I have noticed is there are 3 ldap group lookups that each say "rlm_ldap::ldap_groupcmp: User found in group xxxx". I have read posts about configuring the ldap module to us the inner-tunnel - which I have done. Is there anyway to reduce the number of group lookups to only one? Not sure if the extra lookups are causing unneeded traffic which may be causing issues? Also, I see 10 Access-Request packets and about the same number of Access-Challenge packets.. Is this normal? Just wondering if excessive unneeded traffic is what is overloading the AD/ldap servers? Any help or suggestions will be appreciated. Thanks, Walter Gould Auburn University

Wrong Vlan assignment by freeradius, threading issue?!
by Jan Zacharias 08 Sep '10

08 Sep '10

Hi Folks, I'm running into some very bad issue: when running freeradius in threaded mode (default) it's mixing up CONCURRENT requests resulting in a wrong vlan assignment. Here are the logs of two clients (OSX and Ubuntu). The Ubuntu supplicant (wpa-suppl.) always fails the first login try, but this is normal. This is with reauthentification interval of 10 seconds, so requests seem to overlap: Tue Sep 7 16:45:36 2010 : Auth: Login incorrect: [jan/<via Auth-Type = EAP>] (from client swba1-00-test port 50037 cli 00-1C-25-A2-10-3C) Tue Sep 7 16:45:38 2010 : Auth: Login OK: [jan/<via Auth-Type = mschap>] (from client swba1-00-test port 0 via TLS tunnel) Tue Sep 7 16:45:38 2010 : Auth: Login OK: [jan/<via Auth-Type = EAP>] (from client swba1-00-test port 50037 cli 00-1C-25-A2-10-3C) Tue Sep 7 16:45:39 2010 : Auth: Login OK: [jan/<via Auth-Type = mschap>] (from client swba1-00-test port 0 via TLS tunnel) Tue Sep 7 16:45:41 2010 : Auth: Login OK: [jan/<via Auth-Type = EAP>] (from client swba1-00-test port 50039 cli 00-16-CB-AA-0F-CB) Tue Sep 7 16:45:44 2010 : Error: Discarding duplicate request from client swba1-00-test port 1645 - ID: 208 due to unfinished request 267 Tue Sep 7 16:45:53 2010 : Auth: Login incorrect: [jan/<via Auth-Type = EAP>] (from client swba1-00-test port 50037 cli 00-1C-25-A2-10-3C) Tue Sep 7 16:45:56 2010 : Auth: Login OK: [jan/<via Auth-Type = mschap>] (from client swba1-00-test port 0 via TLS tunnel) Tue Sep 7 16:45:56 2010 : Auth: Login OK: [jan/<via Auth-Type = EAP>] (from client swba1-00-test port 50037 cli 00-1C-25-A2-10-3C) Tue Sep 7 16:45:56 2010 : Auth: Login OK: [jan/<via Auth-Type = mschap>] (from client swba1-00-test port 0 via TLS tunnel) Tue Sep 7 16:45:59 2010 : Auth: Login OK: [jan/<via Auth-Type = EAP>] (from client swba1-00-test port 50039 cli 00-16-CB-AA-0F-CB) Tue Sep 7 16:46:01 2010 : Error: Discarding duplicate request from client swba1-00-test port 1645 - ID: 232 due to unfinished request 291 Now let's check what Vlans got assigned (this is the vmps log, vmps gets only this MAC via rad2vmps and looks up the vlan in a mysql db): ALLOW: 00:16:cb:aa:0f:cb -> Management, switch swba1-00-test.sb.dfki.de [172.16.0.24] port Gi0/39 ALLOW: 00:16:cb:aa:0f:cb -> Management, switch swba1-00-test.sb.dfki.de [172.16.0.24] port Gi0/39 ALLOW: 00:16:cb:aa:0f:cb -> Management, switch swba1-00-test.sb.dfki.de [172.16.0.24] port Gi0/39 ALLOW: 00:16:cb:aa:0f:cb -> Management, switch swba1-00-test.sb.dfki.de [172.16.0.24] port Gi0/39 So freeradius takes the MAC of the OSX client and inserts it into the request that is associated with the Ubuntu client - VERY BAD. Now I only changed the reauthentification interval to 20 seconds, so the requests do not overlap anymore for sure.

Freeradius not unescaping \ and "
by Murray Long 07 Sep '10

07 Sep '10

I have the following setup: CoovaChilli accepts user login requests and sends radius packets to freeradius freeradius then proxies the requests (based on realm) onto a second freeradius server. If I attempt a login with username "A\" The first freeradius server recieves packets with UserName atribute = "A\\" and sends a packet to the sencond radius server with username attribute = "A\\\\" (as reported by wireshark) So it looks like freeradius is not correctly unescaping the username attribute. (Or incorrectly re-escaping) before the proxy. How is freeradius expected to behave when escaping backslash and quote characters before proxying? And is it possible to alter this behavior though configuration? Thanks, Murray

Best Authentication Method for Various Supplicant
by homyang cha 07 Sep '10

07 Sep '10

Hello I am running freeradius-2.17 on CentOS-5.5 box with mysql-5.0.77 as backend and daloradius-0.9-8 as the web management. I have successfully configured an tested EAP-MD5, PEAP and PAP authentication using windows 7 as supplicant with wired 802.1x authentication (no certificates used) and NAS as a Huawei Switch (Quidway S5600 Series) and seems to be working fine. Now my issues are: in my networks there are various kinds of OS running for supplicants. To name a few are Windows XP (SP2, SP3), Windows Vista, Windows 7, Fedora, CentOS, Ubuntu and Mac OS X. I have to configure AAA applicants systems in such a way all this systems are supported. Can someone help me suggest or have any idea/experience on this. What could be the best authentiation method that I can use so that all this supplicants using different OS are supported. Also I use wired connection as well as wireless connection in the network. Does anybody throw some light on this matter? Thanks in Advance -- homyang (aka puran)
