Hi All,

i'm news of newsletter

I believe the more accurate term is "mailing list" :)

, hope to use it well.

I'm studing about freeradius and i've installed a test machine, i would to known if it is possible to define actions to do when radius detects a user disconnections. (I'm thinking about to write some value to a second databases, but question is more general than write something to other db).

Could you give me an advice ?

Generally speaking, radius (not just freeradius, ANY radius server) does not "detects a user disconnections". What happens is radius will know a user is disconnected only if the NAS sends accounting-stop packets. If the NAS does not send accounting-stop (or does not send accounting packets at all), then radius will not know whether the user is disconnected or not. If freeradius DOES accept an accounting-stop packet, you can pretty much configure anything you want with it. Run "man unlang". Using unlang, you could make a rule that says a particular module (e.g. rlm_perl) will be run ONLY when the packet is accounting stop. And if you use rlm_perl, you could pretty much do anything that perl can do, including executing a script, insert data to a database, make HTTP connection, etc. -- Fajar
