I have a working FreeRadius installation used for PPPOE clients using a Mikrotik NAS (Essentialy Linux)

I am using Freeradius to limit data a user can send/receive within a month and automatically reset it every month.

I used an example from chilliuspot hotspot for this.

However what im noticing is sometimes a customer gets denied access because he has exceeded he’s monthly allowance, however when I check the

Db this is not the case cause it’s the beginning of month.

This only happens sometimes so im lost!

I use sqlcounter.conf for the counter part of things and INCLUDE this from radius.conf.

sqlcounter monthlytraffic {

                 counter-name = Monthly-Traffic

                 check-name = Max-Monthly-Traffic

                 reply-name = Mikrotik-Xmit-Limit-Gigawords

                 sqlmod-inst = sql

                 key = User-Name

                 reset = monthly

query = "SELECT SUM(AcctInputOctets - GREATEST((%b - UNIX_TIMESTAMP(AcctStartTime)), 0))+ SUM(AcctOutputOctets -GREATEST((%b - UNIX_TIMESTAMP(AcctStartTime)), 0)) FROM radacct WHERE UserName='%{%k}' AND UNIX_TIMESTAMP(AcctStartTime) + AcctSessionTime > '%b'"

}

Anybody for input? I would greately appreciate help here! A Work around is to simply increase he’s allowance till he is allowed to connect!
