(RADIATOR) SNMP, Simultaneous-Use and Redback SMS500

[Hugh Irvine]

Hello Sven -

There are many readers of this list who use Redback equipment, and there 
are people at Redback on this list as well.

Radiator maintains one or more session databases (in memory, SQL, 
DBM, ...) and tries to keep track of current sessions by using the 
accounting starts to add records and accounting stops (and access 
requests) to delete records.

The NAS itself is only contacted if Radiator detects what it thinks is a 
simultaneous-use exception, and then only if the NasType parameter is 
set in the corresponding Client clause(s). In this situation, Radiator 
goes through the list of sessions for the particular user and queries 
the NAS(s) to verify that the sessions are still active. If any session 
has gone away, that record in the session database is deleted and the 
connection is allowed to proceed. If on the other hand, all the sessions 
are still active, then the connection is rejected.

You will find the mechanisms used to query the different NasTypes in 
section 6.5.5 of the Radiator 3.1 reference manual ("doc/ref.html") and 
you will find the corresponding code in the "Radius/Nas" directory.

regards

Hugh
