Integration with CISCO Router for PEAP requests
by Andras Ionut 30 Aug '12

30 Aug '12

How can I configure FreeRADIUS to work with a CISCO Router and a captive portal in the following case... 1. User tries to access WiFi network with good user and wrong password 2. FreeRADIUS should send Access-Accept with Filter-Id set to portal redirect policy and not Access-Reject 3. User is presented login page, bla, bla, bla My problem is that i have to send an Access-Accept on failed login for PEAP (For TTLS I've managed to do it from config, but this is another story) Thanks in advance, Andras

Ok, that makes sense, would work better I think if I had an include file similar to the users file in a sense, which I assume I can do but not tried in the middle of a section, I could then ditch the users file. Problem is "users" is kind of nice, plus it's marginally easier to read for the less experienced of the network team here than unlang would be, so undecided there. I've tried the operator syntax again, and it seems from playing around a little more that I need a value following the !* operator, i.e. Reply-Message !* "". Is this correct? Thanks again, and I'll consider your suggestion Alan.

Simple attribute question!
by Franks Andy (RLZ) IT Systems Engineer 29 Aug '12

Hi I have a seemingly simple thing I need to do, however it doesn't seem to be working. In the users file I do a quick match to see if a user is in the regex list I put in (this is for overrides of an ldap group, determining higher privileges, but still basic access for the group users), and then another regex checking against a certain ip range : DEFAULT User-Name =~ "frankdsa|everdstons|kirddksa|kefls", NAS-IP-Address=~"192.168.104.*" Reply-Message += "Welcome %{User-Name}\n", Reply-Message += "Admin access", Cisco-AVPair := "shell:priv-lvl=15" This adds a couple of reply messages when the user logs in. Of course the users file is pre-auth so it doesn't care if the ultimate request gets rejected or not based on authorization or some other check. Therefore I've added this to the post-auth-type reject section of the default virtual server: Post-Auth-Type REJECT { update reply { Reply-Message := "Authentication failed}" } It may be wiser to return nothing, i.e. Reply-Message := "" for security reasons, but the point is that the reply-messages set in the users file still pass through, so I get Welcome (username) Admin Access Authentication Failed All together. Am I doing something wrong? I also tried Reply-Message !* , but this stopped the service firing up ( version 2.10 - I see this was talked about being fixed in 2.8?), or Reply-Message -= "%{reply:Reply-Message}" Which didn't work either. Any ideas? Thanks Andy

Hello guys, A quick question, can we have different Huntgroup's with similar NAS ip address? for e.g. OTA NAS-IP-Address == 11.1.200.49 Device NAS-IP-Address == 11.1.200.49 NetworkArchitecture NAS-IP-Address == 11.1.3.252

variable expansion in update coa
by Chocoflex Mamba 29 Aug '12

Hi everybody ! I've configured freeradius with an ldap backend. I had to create new attributes that are sent correctly in the reply. But when i try to put these attributes in the "update coa", the value of these variable are empty. I've tried the syntax %<reply>Attribute-Name but it's still empty. Here the debug output if someone can give me a hint : ... adding new socket proxy address * port 54865 ... adding new socket proxy address * port 44764 Listening on authentication address * port 1812 Listening on accounting address * port 1813 Listening on proxy address * port 1814 Ready to process requests. rad_recv: Access-Request packet from host 127.0.0.1 port 43501, id=62, length=93 User-Name = "testuser" User-Password = "mypasswd" NAS-IP-Address = 172.20.13.27 NAS-Port = 0 Framed-IP-Address = 192.168.1.5 Acct-Session-Id = "539848" Message-Authenticator = 0x92985a75e680a1d422ceb47ba117ea62 # Executing section authorize from file /etc/freeradius/sites-enabled/wol +- entering group authorize {...} ++[preprocess] returns ok [chocoldap] performing user authorization for testuser [chocoldap] expand: %{Stripped-User-Name} -> [chocoldap] ... expanding second conditional [chocoldap] expand: %{User-Name} -> testuser [chocoldap] expand: (uid=%{%{Stripped-User-Name}:-%{User-Name}}) -> (uid=testuser) [chocoldap] expand: ou=wol,dc=labingesys,dc=lan -> ou=wol,dc=labingesys,dc=lan [chocoldap] ldap_get_conn: Checking Id: 0 [chocoldap] ldap_get_conn: Got Id: 0 [chocoldap] attempting LDAP reconnection [chocoldap] (re)connect to 172.20.13.25:389, authentication 0 [chocoldap] bind as cn=admin,dc=labingesys,dc=lan/chocolab to 172.20.13.25:389 [chocoldap] waiting for bind result ...

Problem with Nortel hardware
by Zakrocki, Robert 29 Aug '12

29 Aug '12

Dear list, We have rather strange problem with Nortel hardware and freeradius. We run freeradius-2.1.12-3 on Red Hat 6 in our organization. Our setup is as follows: We have two type of wireless hardware Nortel and Aerohive. We have two radius servers. Windows Radius which is connected to AD and Freeradius server which proxy to the Windows Radius. Our freeradius setup works perfect with Aerohive hardware but unfortunately it doesn't work with Nortel. In our freeradius setup we strip @domain.name from the username (in realm section), and we pass the request to the Windows Radius, this seems to work with Aerohive hardware, but when trying to do the same with Nortel hardware, Windows Radius indicates that we are sending a username(a)domain.name (and it fails there), in other words the username does not get stripped. I wonder why this is happening only to a Nortel hardware and it works perfect with Aerohive? Many thanks, Robert

Bug/Enhancement request: Race condition with short-term accounting (FreeRadius 2.1.10)
by Matthias Nagel 29 Aug '12

29 Aug '12

Hello everybody, if two accounting messages for the same session are sent by the authenticator very quickly, the messages may be processed by the radius server in the wrong order. This results into two sessions being accounted instead of one. The second "phantom" session stays open for ever, because it never receives any update and/or stop message. Example: If a supplicant authenticates and immediately disconnects again, the following steps are executed: 1) The authenticator sends an accounting start message 2) The authenticator sends an accounting stop message immediately 3) The RADIUS server receives the start message and assigns it to thread #1 4) The RADIUS server receives the stop message and assigns it to thread #2 5) Thread #2 terminates first and the accounting stop message is written to the PostgreSQL database. The SQL UPDATE statement fails, because there is no entry for this session that could be updated, as the start message has not been processed yet. Hence, an INSERT INTO statement is executed as a fail-over measure. 6) Thread #1 terminates and an SQL INSERT statement is performed in order to log the start message. The result is, that the same session is accounted with two entries in the database. The first entry is complete, this is to say it has a start and stop time. This is the result of step 5. The second entry is incomplete, i.e. it only has as start time. The latter never will be completed, because the stop message has already been processed and acknowledged to the authenticator. At the moment my work around is to run FreeRADIUS in debug mode to keep it single threaded. But I would like to propose the following solution. Instead of assigning incoming requests to the thread pool randomly, first preprocess the request and assign requests that have identical user names (or some other senseful attribute) to the same thread. This way requests that might belong to the same session are processed by the same thread and cannot outperform each other. Requests that never can belong to the same session are still processed concurrently.
