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 > Hi, has anyone any eyperiences with the upper configuration? > > I'm also interested in the function, how radiator checks via snmp that > an > account is use.
