You can configure FreeRADIUS to store all of the accounting information in one file in the same directory. Look at the etc/raddb/modules/detail file for instructions on how to change where accounting information is logged. The default detail file name is:        detailfile = ${radacctdir}/%{Client-IP-Address}/detail-%Y%m%d. You could change it to:        detailfile = ${radacctdir}/detail-%Y%m%d and the accounting information would be written to one file independent of the NAS.

Subject: accounting question

Hi,
I have redundant NAS nodes and they obviously have two different NAS-IP. If one NAS fails, the entity for which I'm accounting traffic is automatically switched over to the redundant NAS which  can keep sending accounting records to Radius. However, the records  will have different NAS-IP, NAS-Identier and NAS-Port-ID.

The acct-session-id and framed-ip-addrss will be the same (and this is what I use to identify the entity for which I collect acct info). Is there any way that this new records will be written to the same file as before the failover so that I can correlate the records?

I see that the acct directory is in /var/log/freeradius/radacct/<NAS-IP>/. This <NAS-IP> directory name is what is bothering me. Is there any way to change this?
Thanks
Marlon
