OS: Using Ubuntu / Freeradius for user authentication. NAS is mikrotik ver 6.x Scenario: I am trying to implement 'different bandwidth for day & night' from 8am-till-8pm > 1mb from 8pm-till-8am > 2mb I dont know much about freeradius inside core, therefore so far I have think of following, I have created separate table in which i have a dded username / bandwidth for night, start/end time / COA sent flag. mysql> select * from users_bwsch; +----+----------+-----------+----------+----------+------------------+----------------+ | id | username | bwpkg | start | end | start_alert_sent | end_alert_sent | +----+----------+-----------+----------+----------+------------------+----------------+ | 1 | zaib | 2048k/2048k | 11:00:00 | 20:00:00 | 0 | 0 | +----+----------+-----------+----------+----------+------------------+----------------+ I know howto use COA, but confused on howto do multiple IF statement in ACCOUNTING section 1) Using UNLAG query in FR , check the start and end time and match with NOW, if time matches, & start_alert_coa flag is 0 then send COA and update start_alert_sent to 1, when time ends, send COA to change pkg to original one and set FLAG end_alert_sent to 1, and something more ... OR 2) Using external script to do the checking and send COA using radclient? I believe there might be more suitable methods to achieve this , that is why I am seeking help from list members.
