Accounting-Packets from Huawei NAS randomly not being written to the database

[Antônio Modesto]

Hello everyone,


I have some radius servers configured to use decoupled-accounting to avoid overwhelming the database with real-time writes. In all of them I am having the same problem. Some accounting packets sent from Huawei devices are not being written to the database. I have set up a second detail log file to check if the packets were being sent by the NAS. For example:


Packet received from the NAS, stored in the second detail file:

Record in the redacct table:

-[ RECORD 5 ]-------+----------------------------------
username            | andersonoliveira
acctsessionid       | TI5-BRA00304080500000a598ccAAADbA
acctstarttime       | 2020-08-07 08:51:23-03
acctlocalupdatetime | 2020-08-07 08:51:23-03
acctstoptime        | 



As you can see, neither acctlocalupdatetime or acctstoptime were updated with the correct timestamps from the packet received by the NAS. I checked the logs and I couldn’t find any error message related to this. As the server is in production, enabling the debug creates a lot of output.

The only thing I think could be causing this is this condition I have in my accounting section:

if (noop) {
	ok
}

What do you guys suggest?


Thanks in advance.
