So VERY True, Too many late nights and I really do appreciate your input as
this gave me food for thought and I now have EVERYTHING Working.
Both for Traffic & Session USAGE.
For Usage, I still had to use Max-Monthly-Traffic as a Check := and based on
sqlcounter calc, do a Reply = Sessions-Octets-Limit = XXXXXX on the
Access-Accept as this is supported by the ppp 2.4.4 NAS.

Be aware that sqlcounter were originatly designed to count time ..... I remember it has a mechanism to allow user not to be disconnected when its time left is greater than the time remaining to the 'reset period'.<BR>
as an example: if you have 2min left in your account and you connect the 31th of the month at 23h59 (supossing reset period is on the 1st of each month at OhOO), then your session-timeout will not be 120 sec (2min) but will be 120sec + the amount of time allowed for the next month (which starts in 2 minutes)... this allow users not be disconnected stupidly at end of month.<BR>
<BR>
This mechanism is helpfull for time based counter but is meaningless for volume based counter. it would means you get the next month quota addded IF the number of the seconds untill the end of the month is less than the number of allowed octet at present time... weird!<BR>
<BR>
Check at the source code but I am sure this code existed in 2.1.1 version.<BR>

What I would like to know now, is how I can use sqlcounter to do a Month
Calculation based on the date of the account being registered and NOT the
Calander Month? Anyone?
