(RADIATOR) MaxSessions

[Hugh Irvine]

Hello Andrea -

Yes this is always a problem if you don't get proper accounting stop 
records.

Radiator is written so that the session database is maintained firstly 
by the accounting starts (insert) and accounting stops (delete), but 
also by the initial access request which causes a delete on the session 
database by using just the NAS-Identifier (or NAS-IP-Address) and the 
NAS-Port. This is based on the "traditional" NAS model in which the 
NAS-Port is unique and can only support one single connection at a 
time. In addition, if your NAS equipement is supported by one of the 
"NasType" options in the <Client ...> clause, you can configure that as 
well which will cause Radiator to query the NAS to determine whether or 
not a session marked in the session database is still actually 
connected (this may require additional Perl modules and/or NAS 
configuration - check the manual for details).

Hope that helps.

regards

Hugh

NB: have you included a copy of your configuration file (no secrets),
together with a trace 4 debug showing what is happening?
