I have a setup as shown in the below figure (CUIissue.jpg)
The mailing list strips HTML attachments.
At step 3. the proxy AAA add the CUI to the radius access packet.and step 4 forward it unmodified to the NAS.
NAS is supposed to send the CUI with the radius accounting requests, however the NAS is not supporting that and dropping the cui value.
The NAS has to support the CUI for it to be sent in accounting packets.
I read about the cui support in freeradius however it seems to be used in generating a new one and adding to the packet. In this case I need to add the CUI receiving from the proxy AAA to the accounting packets coming from the NAS.
Store the CUI in a database,
I could record the received CUI at step 3 and add that value to the accounting packet at pre-proxy stage 5>6, however the challenge is to find a correlation between the packets.
See the default accounting queries. Look at the User-Name, NAS-Port, NAS-IP-Address, etc. The simple answer is to (as always) read the debug output. Look at the Access-Request and Accounting-Request packets. See which attributes are the same. The information you need *is* available to you. You just need to read it. Alan DeKok.
