Compiler Warnings on ArchLinux and on openSuse
by Matthias Beyer 16 Nov '12

16 Nov '12

Hi there, I'm new to this list, but anyway I hope I can ship all information you need. I had to compile the newest Version (2.2.0) of the FreeRadius-server today at work on a openSuse server (I think it's 11 or 12, 64 bit). There were 2 or 3 compiler warnings because in xlat.c[0] some functions could not be referenced. Anyway, I know how to write C code and I thought "Oh, maybe I could fix this and send a patch when I'm at home". So I did. I forked the repository at github and startet with ./configure make But at home, I run ArchLinux (64 bit machine). There were tons of compiler warnings. I am not planning to install the software on my personal machine, but maybe this is interesting for someone. I could send you the whole output of './configure' or the output of 'make' if you want to have it.

EAP-SIM authentication failed
by Yann R. Moupinda 15 Nov '12

15 Nov '12

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: . . . Listening on authentication address * port 1812 Listening on accounting address * port 1813 Listening on authentication address 127.0.0.1 port 18120 as server inner-tunnel Ready to process requests. rad_recv: Access-Request packet from host 192.168.10.212 port 38803, id=29, length=238 Service-Type = Framed-User Framed-MTU = 1400 User-Name = "1901700000000653" NAS-Port-Id = "ap_hotspot" NAS-Port-Type = Wireless-802.11 Acct-Session-Id = "8220000e" Acct-Multi-Session-Id = "00-0C-42-64-41-9D-A8-7E-33-3E-9C-5B-82-20-00-00-00-00-00-0E" Calling-Station-Id = "A8-7E-33-3E-9C-5B" Called-Station-Id = "00-0C-42-64-41-9D:YANN" EAP-Message = 0x020100150131393031373030303030303030363533 Message-Authenticator = 0xcf4e5f6429686cc260b16bd23d82489f NAS-Identifier = "MT_Yann" NAS-IP-Address = 192.168.10.212 # Executing section authorize from file /etc/freeradius/sites-enabled/default +- entering group authorize {...} rlm_sim_files: authorized user/imsi 1901700000000653 rlm_sim_files: Adding EAP-Type: eap-sim ++[sim_files] returns ok ++[preprocess] returns ok ++[chap] returns noop ++[mschap] returns noop ++[digest] returns noop [suffix] No '@' in User-Name = "1901700000000653", looking up realm NULL [suffix] No such realm "NULL" ++[suffix] returns noop [eap] EAP packet type response id 1 length 21 [eap] No EAP Start, assuming it's an on-going EAP conversation ++[eap] returns updated ++[files] returns noop ++[expiration] returns noop ++[logintime] returns noop [pap] WARNING!

AcctSessionId UNIQUE
by Lorenzo Milesi 15 Nov '12

15 Nov '12

Is there any contraindication in marking the radacct.AcctSessionId column UNIQUE? >From what I've read by researching in old threads, and looking at the current source [1], it looks like there is no one. I'm still using old FR 1.1.7. I know this is a sympthom of something else, and I already investigated and found the solution, but while I wait I get this activated I need to mitigate the problem. thanks [1] https://github.com/FreeRADIUS/freeradius-server/blob/master/raddb/sql/mysql… -- Lorenzo Milesi - lorenzo.milesi(a)yetopen.it GPG/PGP Key-Id: 0xE704E230 - http://keyserver.linux.it

Complex eduroam radius design
by Olivier Beytrison 15 Nov '12

15 Nov '12

Hello, We're planning to deploy eduroam centrally for all the university of applied science of west-switzerland. (consists of ~27 schools and 25'000 people). On one side, we will have the central radius servers, connected to the central ldap backend which contains all the user account. On the other side, we will have local radius servers (about 7 pairs of servers, because the schools are grouped regionally and under a central management). The idea is the following : User join the WLAN (802.1x, eduroam). the WiFi controller (nas) contact the local radius for authentication, which in turn contact the central radius to authenticate the user. upon successful authentication, the central radius return the Access-Accept along with some custom attribute about the user. The local radius then perform admission control based on those attributes. (selecting the correct vlan, subnet, ect) So I have two questions : 1. is this implementation possible ? 2. If it is possible, will the inner-tunnel for eap-peap and eap-ttls end on the local or central radius, taking in account that the authentication is performed by the central radius. (I'll go for the central one) Thanks in advance for your answers. Best regards, Olivier B. -- Olivier Beytrison Network & Security Engineer, HES-SO Fribourg Mail: olivier(a)heliosnet.org

Re: accounting data
by Dirk van der Walt 15 Nov '12

15 Nov '12

Hi, I've done the same exercise on my side and have the following observations based on the debug output. 1.)The rlm_counter is only interested in Accounting Stop packets. 2.)If I send two subsequent Accounting Stop requests using the radclient and the file with the Accounting Stop AVP bundles, only the first one is used and the second one is ignored due to the fact that the packet with the unique ID is already recorded in the database and thus ignored: rlm_counter: Packet Unique ID = '9c5a417fc48a9b9e' rlm_counter: Searching the database for key 'aclice' rlm_counter: Key found. rlm_counter: Counter Unique ID = '8d3af3931deff832' rlm_counter: Unique IDs for user match. Droping the request. The Packet Unique ID is created by the acct_unique module in the preacct section: [acct_unique] WARNING: Attribute NAS-Identifier was not found in request, unique ID MAY be inconsistent [acct_unique] Hashing 'NAS-Port = 0,,NAS-IP-Address = 127.0.0.1,Acct-Session-Id = "4D2BB8AC-00000099",User-Name = "alice"' [acct_unique] Acct-Unique-Session-ID = "9c5a417fc48a9b9e". ++[acct_unique] returns ok This is covered in the pre-accounting section on page 133. Since this is a simulation, in the real world the next packet will have a different value for Acct-Session-Id. So by simply changing the value of Acct-Session-Id to 4D2BB8AC-00000099 in these files containing the AVP bundles and running the session simulation again you can see the following: rlm_counter: Packet Unique ID = '56a4675037d8b965' rlm_counter: Searching the database for key 'aclice' rlm_counter: Key found. rlm_counter: Counter Unique ID = '8d3af3931deff832' rlm_counter: User=aclice, Counter=30. rlm_counter: User=aclice, New Counter=60. rlm_counter: Storing new value in database. rlm_counter: New value stored successfully. ++[daily] returns ok So the important thing to remember if you want simulate a user's session is that the value of Acc-Session-Id needs to be unique for every simulated session. A session simulation will consist of an Accounting Start and Stop request (and also may include optional Accounting Interim-Update requests). With that in mind, refer again to the description of Acct-Session-Id on page 131. Although rlm_counter is primarily used as an introduction here to better understand the counter modules, the next section covers the rlm_sqlcounter module. This module is more flexible and preferred. Hope this helps you.

Best way to capture RADIUS passwords
by Chris Taylor 12 Nov '12

12 Nov '12

I am migrating from one RADIUS setup that checks against a flat file with usernames and passwords inside it . Over to a RADIUS server with and LDAP backend. I have used JTR to crack most of the passwords but I still have some left over that JTR cant crack. I was thinking of trying to run a packet capture to get the remaining usernames and passwords. What would be the best way to do this? Run RADIUS in debug mode Radius -X? Or try to use tcpdump and pick it up that way or is it even possible to do? I have been trolling the internet for a few days and have not come up with a good way to do it. I setup tcpdump to dump to a file (tcpdump -i eth0 -n -s0 port radius -w rad-capture.lpc) , but when I check it out with wireshark I am unable to see the password (just the username). Am I going about this the wrong way? Thanks, Chris
