Hi, sometimes i have duplicate accounting start packets in my details-file and in the database. This might be a general problem for billing and i'd like to know, how some of you handle this.
That's what i found out so far: The first start-packets is written, but the NAS gets no acknowledge from the radius sometimes, so it retransmits the packet after a timeout of a few seconds. This second packet is also written to details and database. Because it has the same Acct-Unique-Session-Id, the billing runs into problems. The same duplicate start-packets are produced, when the primary radius goes offline and the secondary gets a therefore retransmitted startpacket - which is written like the first attempt to the database. How do you select the "right" start-packet for a session? Regards, Oliver - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
