The RFC's specifiy that those attributes go into a 32-bit integer in the RADIUS packet. FreeRADIUS is therefore limited by the RFC's.
Understood.

FreeRADIUS has no control over that.

There is no real solution, other than having the provider send the Gigawords attribute. FreeRADIUS can't log information it doesn't have.
Understood.
What may *help* is that if your provider sends accounting packets quickly enough (like every 10 minutes), to keep track of the *last* value for Access-Input-Octets. If the new value is smaller than the old one, yuo can "guess" that it rolled over, and add 2^32 to the new value.
Yep, I had decided to proceed this way if I had no real alternative, I havent
as yet asked if my provider can drop the intrim updates down to a shorter
period.
It's a hack, but it will help. It won't be perfect, though.
Agreed.

Collects *what* data? You just said that the provider wasn't sending Gigawords attributes to you. Why would another daemon be able to do something that FreeRADIUS can't?
Our provider tells me they have no problems sending Input and Output
data fields upto very large sizes, Im presuming they are telling the truth. Therefore
in theory if I wrote my own daemon to sit on the port and collect the accounting
records, I can then place the Acct-Input-Octets and Acct-Output-Octets values
in variables that are of a type that can handle the size, I can then directly enter these
values into my database and forward a copy of the record to freeradius.
In theory of course I have no idea if this will work at the present time.
Thanks for your input.
Cheers
Mike
