freeradius query on password encryption and decryption
by Yashaswini Sathyanarayana 21 Dec '12

HI, I am using seagull testing tool to send messages to free radius. I am running seagull with "radius protocol ". When i send messages from seagull to freeradius , the password is not getting decrypted properly on radius side. Can you please tell me how to send password from seagull without encryption ?? OR What changes to make on freeradius side to make it decrypt the password?? Thanks & Regards, Yashaswini | Prod Engg | Tech Mahindra Ltd. 9 / 7 Hosur Road, Bangalore - 560029, India.

It is noticed that some VSAs are sent with Access-Challenge but not with Access-Accept when PEAP is used. Is there a way to configure the server such that those attributes are sent with Access-Accept? Thank you.

user-agent as authentication
by Budiono Untung 20 Dec '12

Hi All, I would like to make wifi hotspot , with user-agent as authentication to freeradius . The scenario is like this: If the user-agent is 'a' then it will rejected and if user-agent is 'b' then it will be allowed to login page that connected to freeradius as authenticator. Is above scenario will be possible ? TIA, Dion

Return Access-Accept/-Reject depending on other active sessions during post-authentication
by Matthias Nagel 18 Dec '12

18 Dec '12

Hello together, my NAS supports used-based authentication, this means it is possible to have multiple sessions on the same ethernet port (same user multiple times and/or different users). Each attached supplicant must authenticate itsself. The switch prohibits a supplicant to use piggy-backing on top of some other already authenticated supplicant. Moreover I use RADIUS-assigned VLANs. If the same user or different users that are assigned to the same VLAN are authenticated on the same port, everything is fine. The trouble starts, if an additional user with a different VLAN than the VLAN that is already assigned to the port is sucessfully authenticated. In the past an additional user was denied access by the switch, if such a VLAN mismatch occured. This means is was impossible to have serveral different untagged VLANs on the same port. But my current NAS also grants access to the addtional user and assignes this user's VLAN to the port, too. This means there are more than one untagged VLAN on the same port at the same time and the result is some kind of "short-circuit fault" between the affected VLANs. Now, I would like to write some kind of RADIUS policy to prevent this behaviour. This policy is supposed to do the following during the post-authentication phase: 1) If there is no active session on the NAS port, just return Access-Accept 2) If there is at least one active session on the NAS port and the 'Tunnel-Private-Group-ID' of that session equals the 'Tunnel-Private-Group-ID' of the new request, return Access-Accept. 3) If there is at least one active session on the NAS port and the 'Tunnel-Private-Group-ID' of that session DOES NOT equal the 'Tunnel-Private-Group-ID' of the new request, return Access-Reject. Is this possible to do? I have the accounting information in a SQL database, hence I know, if there are active sessions on some port. But I do not know, which would be the correct RADIUS configuration section and I do not know if "unlang" or some other configuration directive can perform such a check.

freeradius+mysql
by nanthitha shanmugam 18 Dec '12

18 Dec '12

Hi, I am using mysql with free radius for user authorization and accounting with assignment of ip pools from iptables in mysql. These all are working. But, I would like to know if we can bypass the authorization phase with mysql and use only ip pool assignment. Can you help in this part. Like even if the user is not authenticate, I wanted to send always access accept message with a framed ip from the ip pool table. Thanks, Nanthitha

Hi all, i have found problem in xlat.c code. Original code doesn`t work when i want to use in acct_users: DEFAULT Called-Station-Id == "orangewap" Called-Station-Id := "%{Called-Station-Id}.%{3GPP-SGSN-Address}" I have changed xlat.c [radiusd@tdrad1 main]$ diff xlat.c xlat.c.backup 1043a1044,1046 > if (isdigit(*p)) { > module_name = xlat_str = p; > } else { 1045a1049 > } Now everythink works correct.

Xlat iterate over sql result
by Stanislav Lorenc 16 Dec '12

16 Dec '12

Hi, is there some way how to iterate over xlat sql query result ? For example: I need send for user multiple ipv6 prefixes and they are stored in sql table and each prefix is represented by record in table. Query return for example 4 rows. update reply { Framed-IPv6-Prefix := "%{sql:SELECT network FROM ipv6_prefixes WHERE service = "user_service" }" } I am not able to find solution how to add all this records into reply. Best Regards Stanislav Lorenc

Simultaneous Proxy of Acct Messages to two External Radius Servers Using Replicate-To-Realm
by Jason Everard 15 Dec '12

15 Dec '12

We have been trying to get freeradius to work to do something I know works because I have seen it posted to this list on a few occasions. We have a Radius NAS (Cisco WLC) that is sending auth data to multiple Radius servers (not freeradius rather MS NPS and Cisco ACS and Cisco ISE) Problem is that we have several Radius receivers that need to see all of the accounting records from the WLC to make decisions re: the 802.11i session. So the sole function of the freeradius deployment is to proxy all received accounting packets to multiple Radius receivers simultaneously. We have been trying to get it to work with "Replicate-To-Realm := ISE" in the corresponding virtual-server configuration, however it doesn't work. The only way we can get the freeradius installation to send accounting packets to another external radius box is to use "Proxy-To-Realm" which requires a response from the server and does not seem to send the radius accounting packets to more than the first realm listed, i.e. preacct { preprocess update control { Replicate-To-Realm := ISE Replicate-To-Realm += BlueCoat } Doesn't work at all. However, the following will send the accounting packets to the ISE realm and NOT to the BlueCoat realm until the ISE realm is marked dead. preacct { preprocess update control { Proxy-To-Realm := ISE Proxy-To-Realm += BlueCoat } We want the Replicate-To-Realm functionality where the behaviour is to "send-and-forget" and to NOT require an accounting response from either server and where all packets are sent to ALL realms listed. We are running 2.1.12 currently. Is this maybe a bug that is fixed in 2.2.0? Regards, Jason

Dear Freeradius Hackers, This is new implementation. Can someone help me to troubleshoot why freeradius mysql authentication is failing. i have cross check every expect but still seem that something is not in place.
