Log says "duplicate requests", CPU maxing out
by Chhaya, Harshal 11 Mar '09

Thanks to Alan, we are now running freeRADIUS 2.1.3 on our embedded network controller. The problem is that now it is less stable than the 1.1.7 version we had been using. Again, I am sure our config is screwed up. For example, the 'radius.log' file contains dozens of files saying: Error: Discarding duplicate request from client test-net port NNNN - ID: XX due to unfinished request YYY The client.conf file has this entry: client 192.168.0.232/24 { secret = testing123 shortname = test-net } The config uses a flat file with uernames and cleartext passwords. There is no SQL database in the backend. Also, when we have 40+ clients attempting to connect to RADIUS, the CPU utilization reaches 100% and the processor becomes unresponsive. The 'maxserver' parameter in radiusd.conf is set to 32 (as it was for the older version). I am upping it to 64 to see if that solves the CPU problem. Thanks for any insights. Regards, - Harshal

Freeradius 2.1-1: failure modes
by leopold 11 Mar '09

11 Mar '09

Guys, I have a question about different failure modes in FreeRadius, basically I want to differentiate between different scenarios of failures and return a proper response (if any) to NAS device. Failure example: Backend database is down Right now FreeRadius returns reject to NAS rlm_sql (sql): Failed to connect DB handle #8 rlm_sql (sql): reconnect failed, database down? rlm_sql_getvpdata: database query error [sql] SQL query error; rejecting user rlm_sql (sql): Released sql socket id: 8 ++[sql] returns fail Sending Access-Reject Say I do not want to return reject in this case and I want the switch to understand that radius is down and retry another radius server (a backup/failover). Because if I return reject the NAS device treats this as radius is UP and running. What is recommended behavior for Radius for: DB is down,Authentication infra is down(say kerberos is down)? Should it return REJECT or NOOP? Thank you very much for your responses.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello All, I am using freeradius 2.1.1 on Suse 10 SP1. I am trying to integrate Freeradius with edirectory, but somehow, I am not able to achieve the desired result, the client just sits while trying to authenticate, I can see the Radius server reading the username and password, but still its not authenticating it. Kindly Help.

I was also bitten by the bug where ntlm_auth returns a bad NT_KEY. It took me a few hours of searching the mailing lists before I stumbled across this thread: http://marc.info/?l=freeradius-users&m=123455952011812&w=2 If there were a warning or mention of the issue on the how-to page, it would help users who are just starting to integrate their radius server with AD. http://wiki.freeradius.org/FreeRADIUS_Active_Directory_Integration_HOWTO I would have edited the page myself, but it doesn't look like it's a public wiki. Thanks to the radius guys for a great piece of software. ---------------------------------- Robert G Colantuoni CIT - Operational Support Services University at Buffalo rgc(a)buffalo.edu 716.645.3552

Multiple LDAP Configurations on a single freeradius daemon
by Nils Cant 11 Mar '09

11 Mar '09

Hi, I'm looking for the best way of configuring freeradius (either version 1.1.3 or version 2.1.1) with two separate LDAP configurations. The reason for this, is we've got two different NAS' (VPN client and WIFI) both querying freeradius with LDAP backend for authentication and authorization, but we want to be able to control access to both services with an ldap "accessTo" attribute: ldap { server = "10.0.0.2" identity = "uid=radiusadmin,ou=system,dc=test,dc=com" password = "radiustest" basedn = "dc=test,dc=com" filter="(&(|(accessTo=WIFI_FR)(accessTo=WIFI_ALL))(uid=%{Stripped-User-Name:-%{User-Name}}))" base_filter = "(objectclass=radiusprofile)" ... Anybody got any suggestions on how to have two ldap configurations (two different filters) and have those assigned to a NAS/Client? Thanks in advance, Nils
