Hello, I have configure my FreeRadius to work with MySQL, I also add the sqlcounter to count the hours user after the first login. Here is my code: mods-enabled/sqlcounter: sqlcounter checkthetime { sql_module_instance = sql dialect = ${modules.sql.dialect} counter_name = All-Hours-Passed check_name = Max-Hours-Passed reply_name = Session-Timeout key = User-Name reset = never $INCLUDE ${modconfdir}/sql/counter/${dialect}/${.:instance}.conf } checkthetime.conf: query = "\ SELECT HOUR(SEC_TO_TIME(UNIX_TIMESTAMP() - UNIX_TIMESTAMP(AcctStartTime))) \ FROM radacct \ WHERE UserName = '%{${key}}' LIMIT 1;" sites-available/default: authorize { .... sql checkthetime .... } I am getting this message from the debug mode: (0) WARNING: checkthetime : Couldn't find control attribute 'control:Max-Hours-Passed' I don't know if I have make any syntax error! Thanks for your attention and time!
