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
