Problem with Freeradius2 - Start and Stop connections isn't inserted in BD
by Rodrigo Yoshioka 08 Jun '13

08 Jun '13

Hi, I updated my freeradius to version 2, but now, It isn't inserting in database start and stop connections. Free radius is updating radacct table when it update sessions. So when client connect I'll just have this information in radacct when account update the download/upload data. Do you have any idea about what is happening? Thanks

But free radius> is not sending reject message instead it comes out with an error "no> response from the server". That's how it works. The problem is that the call to SQL is blocking at the OS layer.  i.e.FreeRADIUS isn't running any more for that thread.  So it's pretty muchimpossible *forcibly* stop that SQL query. The solution to a slow database is to fix the database.  PokingFreeRADIUS won't work.  Any changes you make to FreeRADIUS will make theproblem worse. There is NO reason why an S! QL database takes more than .1s to returnfrom a query.  If it does, your database is horribly broken. Alan DeKok.

Free Radius not sending reject message when using "max_request_time"
by manjunath uthappa ponnachana 07 Jun '13

07 Jun '13

Hi, There is a parameter "max_request_time" defined in file radiusd.conf which indicates the maximum time free Radius takes to handle a request. Request which take more time than this will be killed and reject message is sent by Free radius. This problem is most often seen when using an SQL database. Possible range for this parameter is 5 to 120 (in secs) I am trying to test this and trying to execute SQL query from free radius which will take more time than max_request_time. But free radius is not sending reject message instead it comes out with an error "no response from the server". Could anybody please help? Is anything else to be configured in free radius to use this parameter. Thanks & Regards Manjunath

RE: module-failure-message in exec module

Ok, so the other questions stand, but an update to say the problem is the variable is not coming back to the default VS from the inner tunnel which I didn't at first spot. I had this problem recently and couldn't work it out : how do we copy control attributes from the inner tunnel to the outer in PEAP or is it not possible..?
