  FreeRADIUS is a toolbox.  It isn't a complete "product" with a button you can click \
that says "do what I want".

  The solution here is to realize that FreeRADIUS doesn't track users.  FreeRADIUS \
just writes accounting information to a database.  So really, the *database* tracks \
users.

  Which means all you need to do is write a database query that finds sessions which \
haven't seen updates.  Then, use that information to send a CoA packet.

  If you have 3.0.20 installed, this is a lot easier.  There's a sample virtual \
server in raddb/sites-available/coa-relay.  You can send a CoA packet to FreeRADIUS \
with just an Acct-Session-Id attribute.  FreeRADIUS will figure the rest out, and \
send a packet to the NAS.
