Two Simultaneous-Use on Same NAS Port
by Smith, Mark J 25 Mar '09

25 Mar '09

I'm trying to limit a single username to logon 2 times on the same NAS Port/NAS Port ID. Our test environment consists of a single FreeRadius Server (Version 2.1.5/4), MySQL Server 5.0.45, and a Cisco 7200VXR with IOS 12.2(31)SB13. The main issue now is that a single user name with Simultaneous-Use set too 2 is able to login an unlimited number of times on the same NAS Port/NAS Port ID. However, if the same user logon through a different NAS Port/NAS Port ID, Simultaneous-Use checks work as expected. Please, note the following radwho and radiusd -X outputs. radwho -R Output after first user logged in: User-Name = "test1" Acct-Session-Id = "00003377" NAS-IP-Address = X.X.X.X NAS-Port = 2097152 Service-Type = Framed-User Framed-Protocol = PPP Framed-IP-Address = X.X.X.X radwho -R Output after second user logged in: User-Name = "test1" Acct-Session-Id = "00003378" NAS-IP-Address = X.X.X.X NAS-Port = 2097152 Service-Type = Framed-User Framed-Protocol = PPP Framed-IP-Address = X.X.X.X Acct-Session-Time = 72 **Note the lack of the first user identified by Acct-Session-ID 00003377. radwho -R Output with second user logged in through a different NAS Port/NAS Port ID: User-Name = "test1" Acct-Session-Id = "00003378" NAS-IP-Address = 66.109.238.133 NAS-Port = 2097152 Service-Type = Framed-User Framed-Protocol = PPP Framed-IP-Address = 66.216.191.36 Acct-Session-Time = 476 User-Name = "test1" Acct-Session-Id = "00003379" NAS-IP-Address = 66.109.238.133 NAS-Port = 1610625913 Service-Type = Framed-User Framed-Protocol = PPP Framed-IP-Address = 66.216.191.37 Acct-Session-Time = 70 Acct-Session-Id 00003377 radiusd -X output: +- entering group session {...} [radutmp] expand: /usr/local/var/log/radius/radutmp -> /usr/local/var/log/radius/radutmp [radutmp] expand: %{User-Name} -> test1 ++[radutmp] returns ok rad_recv: Accounting-Request packet from host 66.109.238.133 port 1646, id=88, length=136 Acct-Session-Id = "00003377" Framed-Protocol = PPP Framed-Route = "255.255.255.0" Framed-Route = "255.255.255.0" Framed-IP-Address = X.X.X.X User-Name = "test1" X-Ascend-Connect-Progress = LAN-Session-Up Acct-Authentic = RADIUS Acct-Status-Type = Start NAS-Port-Type = 32 NAS-Port = 2097152 NAS-Port-Id = "0/0/2/0" Service-Type = Framed-User NAS-IP-Address = X.X.X.X Acct-Delay-Time = 0 +- entering group preacct {...} ++[preprocess] returns ok Acct-Session-Id 00003378 radiusd -X output: +- entering group session {...} [radutmp] expand: /usr/local/var/log/radius/radutmp -> /usr/local/var/log/radius/radutmp [radutmp] expand: %{User-Name} -> test1 ++[radutmp] returns ok rad_recv: Accounting-Request packet from host 66.109.238.133 port 1646, id=89, length=136 Acct-Session-Id = "00003378" Framed-Protocol = PPP Framed-Route = "255.255.255.0" Framed-Route = "255.255.255.0" Framed-IP-Address = X.X.X.X User-Name = "test1" X-Ascend-Connect-Progress = LAN-Session-Up Acct-Authentic = RADIUS Acct-Status-Type = Start NAS-Port-Type = 32 NAS-Port = 2097152 NAS-Port-Id = "0/0/2/0" Service-Type = Framed-User NAS-IP-Address = X.X.X.X Acct-Delay-Time = 0 +- entering group preacct {...} Cisco Radius Configuration: aaa authentication login default local group tacacs+ aaa authentication enable default group tacacs+ enable aaa authentication ppp default local group radius aaa authorization exec default local group tacacs+ aaa authorization commands 1 default local group tacacs+ aaa authorization commands 15 default local group tacacs+ aaa authorization network default local group radius aaa accounting delay-start vrf default aaa accounting delay-start all aaa accounting exec default start-stop group tacacs+ aaa accounting commands 1 default start-stop group tacacs+ aaa accounting commands 15 default start-stop group tacacs+ aaa accounting network default start-stop group radius aaa accounting system default start-stop broadcast group radius group tacacs+ radius-server attribute nas-port format e SSSSAPPPUUUUUUUUUUUUUUUUUUUUUUUU radius-server attribute nas-port format e SSSSAPPPIIIIIIIICCCCCCCCCCCCCCCC type 30 radius-server attribute nas-port format e SSSSAPPPIIIIIIIICCCCCCCCCCCCCCCC type 31 radius-server attribute nas-port format e SSSSAAAAPPPPVVVVVVVVVVVVVVVVVVVV type 32 radius-server attribute nas-port format e SSSSAPPPVVVVVVVVVVVVVVVVVVVVVVVV type 33 radius-server attribute nas-port format e SSSSAPPPQQQQQQQQQQQQVVVVVVVVVVVV type 34 radius-server attribute 61 extended radius-server host X.X.X.X auth-port 1812 acct-port 1813 non-standard key Please, let me know if any additional information is needed.

I have tried all kinds of config's in the sql.conf file and still get fails I have turned on sqltrace and here is the error we currently get, its not much... rlm_sql (sql): Reserving sql socket id: 2 rlm_sql (sql): SQL query error; rejecting user rlm_sql (sql): Released sql socket id: 2 Right now to retrieve username and password...(sql script) we use this from sql query select Username, Password from Contact where length(Username) > 0; How do I slap that into sql.conf to make it work for simply just username/password auth? Any help would be appreciated.

Re: SAML support for freeRadius
by ALVAREZ SANTANA, LUIS MIGUEL 25 Mar '09

25 Mar '09

Hi Stefan and everybody I´m trying to get an architecture of federation-id in which are involved, layer 2 communications, RADIUS (like FreeRadius) and IdP server, but I have some doubts about it. Searching for information I read this thread, and I decided claim for help.I´m really interested in scenarios 2&3 which were described before > 2) a user logs in with a non-SAML credential. FreeRADIUS should be able > to use a SAML-enabled backend to verify these credentials. > 3) a user logs in with a non-SAML credential. FreeRADIUS uses a non-SAML > backend, but transports a SAML assertion to the user which the user can > later use to enter SAML-enabled resources. In fact, what I was wondering is if it would be possible a mixture between secenarios 2 and 3, I mean, a user logs in with a non-SAML credential (x509 certificate), FreeRADIUS verify the credentials in a SAML-enabled backend (IdP), AND transports a SAML assertion to the user which the user can later use to enter SAML-enabled resources. ¿Is there any way for getting a succesful "SAML-conversation" between FreeRADIUS and an IdP, in which the assertions were sent to FreeRADIUS and since there to the client (in layer 2)? As regards to the use of a layer 2 protocol/method to send SAML attributes, I´ve heard about DAIDALOS that uses PEAPv2 to send and receive SAML assertions between the edges of an EAP layer 2 communication. I´m not sure the latter is contradictory with your previous answer > In that case though, the equally sad answer is that > there is no defined transport to send SAML within RADIUS. What you'd > need then is a means to send SAML payloads in RADIUS attributes. The > most logical way of doing so would be some kind of "EAP-SAML" - but such > a thing doesn't exist as an IETF standard today. So if authenticating > via SAML assertions is something you want to do - please present your > use case loudly to IETF people - they might listen and get going :-) Does it mean that is not possible send SAML assertions in any EAP-method, or only has to do with SAML payloads in RADIUS attributes? Thank you very much for your attention and sorry for that awful English language that I have. Greetings Luis M. Álvarez -- Universidad Carlos III de Madrid

copy-acct-to-home-server
by Emmanuel Rafaralahisoa 25 Mar '09

25 Mar '09

Hi all, I wish to configure 1 proxy radius server and 2 backend radius servers. One backend server is the real database for aauth and billing. The other one is inside a traffic shapper. I want to duplicate all accounting packets to this trafic shapper. After reading many times the proxy.conf and /sites-availables files, I can not forward all request to the traffic shaper until now. Does someone has a clear example for this kind of configuration? Regards. Emmanuel Rafaralahisoa Data Telecom Service.

Seqfault with multiple
by JDL 25 Mar '09

25 Mar '09

Hello to Alan and the rest of the list. I wanted to report this to the bug tracker but it appears to be down right now so I am sending it to the list. I had a situation where I needed to remove all of the attributes from a reply except for Service-Type to one specific client. Unlang seemed to be perfect for this. It should be as simple as the following. if (Client-IP-Address == "192.168.10.20") { update reply { Framed-Protocol == '' Framed-IP-Address == 0.0.0.0 Framed-IP-Netmask == 0.0.0.0 Idle-Timeout == 999 Session-Timeout == 999 Port-Limit == 999 Cisco-AVPair == '' Service-Type := Authenticate-Only } } However, when I try to do this, radiusd segfaults when attempting to run this block. I tried several tests and I could sometimes get up to two lines with "==" operators in an update block to work. However, adding more than two or three would cause a segfault. I was finally able to use the following workaround under 2.1.4. This workaround did not work under 2.1.3. if (Client-IP-Address == "192.168.10.20") { update reply { Framed-Protocol == '' } update reply { Framed-IP-Address == 0.0.0.0 } update reply { Framed-IP-Netmask == 0.0.0.0 } update reply { Idle-Timeout == 999 } update reply { Session-Timeout == 999 } update reply { Port-Limit == 999 } update reply { Cisco-AVPair == '' } update reply { Service-Type := Authenticate-Only } } My system is CentOS 5.2 32-bit. Hope this helps. Thanks, Jim L.

FreeRADIUS / ippool / Wireless
by Tim Gustafson 25 Mar '09

25 Mar '09

Hi, I'm using FreeRADIUS 2.1.3 on FreeBSD 7.1 to authorize users on my Cisco 1200 WAPs. I was wondering if it is possible to use ippools to assign client IPs rather than having them use DHCP, and I Googled around a bit and found a message that said this can't be done. I was curious if it can't be done because it's just something that fundamentally cannot work, or was it something that couldn't be done at the time, but perhaps can be done now or in the future? If it can't be done, I would love to hear any feedback people have about how to map wireless users to IP addresses. Has anyone else figured out a way to be able to record this kind of data without resorting to matching MAC addresses from the radius accounting records with data in a DHCP server log?

monitoring FR's EAP/PEAP capabilities...
by sth 24 Mar '09

24 Mar '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, Has anyone written code to test FR's EAP/PEAP functionality that would work with MS-CHAPv2? I see that 'radeapclient' will do MD5, but need to monitor FreeRADIUS talking to its oracle though rlm_mschap. Something that tested just MS-CHAPv2 would be fine, too, although it seems like rlm_mschap only ever exists inside EAP in the standard FR configs. I'm just looking to see if attempting to write something like this would constitute "reinventing the wheel". (FreeRADIUS 2.1.3 on RHEL 4.7; rlm_mschap modified to work with the unfortunately-named KCRAP[1].)
