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_Acct-O... 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 On Thu, 13 Dec 2007 15:55:00 +1300, "Russell Tester" <russell@serverworks.co.nz> wrote:
Hi All,
I am new to the freeradius list but have been running freeradius for some time. We are changing the way we do some of our accounting here and have a requirement to provide users with monthly prepaid cards for specific data values, namely 1,5 and 10GB.
I have no problems making the pass timeout after the month, that bit is fine using the expiration check value.
Where I am faced with a problem is telling the nas about (we use Mikrotik's) and counting above the hair pulling 4GB boundary.
An example of my sqlcounter is below, this works perfectly fine anywhere up to 4GB, note that I run two of these one for up and one for downloaded data. Not 100% accurate in terms of the user could theoretically get the max amount of data up and down from their first session but accurate enough for us for now. I believe Mikrtoik v3 has a Total-Limit attribute which will fix this when its released.
sqlcounter prepay-data-down { counter-name = Max-All-Session-Data check-name = Max-All-Data reply-name = Mikrotik-Recv-Limit sqlmod-inst = sql key = User-Name reset = never query = "SELECT SUM(AcctInputOctets) + SUM(AcctOutputOctets) FROM radacct WHERE UserName='%{%k}'" }
Two problems exist with this setup:
1. When I specify a larger than 4GB value in radcheck I get an Access-Reject. 2. I have no way to send the equivalent gigawords attribute to the NAS as well, I believe I need to send both the Mikrotik-Recv-Limit and Mikrtoik-Recv-Limit-Gigawords values.
I have spent some time playing myself and have managed to send the gigawords attribute by using another sqlcounter, and another radcheck attribute for gigawords, but get lost somewhere in the middle of checking both the gigawords and octets values against the radacct data and getting a sensible reply from them.
The other question I have relates to the action the sqlcounter performs when the limit is reached. Is there any way to modify the reply attribute that gets passed to the nas when the limit is reached? Either by changing the reply message, or passing say a rate-limit value to the NAS to throttle the user.
Any help to get this working, or examples of existing setups would be greatly appreciated.
Cheers, Russell Tester
