sqlcounter, counting data and large amounts of it

[Russell Tester]

CoMeC,

Thanks for your reply, Yes I have read the FAQ, and understand why we
need to wrap at 4GB, just can't get a solution working to limit users
above 4GB. Accounting works fine above 4GB. 

We have been using Mikrtoik with Freeradius for around 4 years, yeah it
works good :)

Btw I forgot to mention I'm using 1.1.7.

Thanks,
Russell Tester

Hey,

I don't know if I understand everything correctly, but just take a look
at
this:

http://wiki.freeradius.org/index.php/FAQ#Why_do_Acct-Input-Octets_and_Ac
ct-Output-Octets_wrap_at_4_GB.3F

Maybe that is the solution.

Are you using Mikrotik? Any issues? 
I am going to use it too, so I am very curious! :D

Best regards,

CoMeC
