Hello Dear, I use time counters to limit session time without any problem. Now, on the same system, I must also configure the traffic limit. The problem is that if you use a traffic counter (daily or monthly), the user stays connected even if the quota is exceeded. To do it, I proceeded like this: # nano /etc/freeradius/3.0/dictionary and add this: ATTRIBUTE Max-Monthly-Traffic 3003 integer ATTRIBUTE Monthly-Traffic-Limit 3004 integer #nano /mods-config/sql/counter/mysql/monthlytrafficcounter.conf and add this: query = "SELECT SUM (acctinputoctets + acctoutputoctets) FROM radacct WHERE UserName = '% {$ {key}}' AND UNIX_TIMESTAMP (AcctStartTime)> '%% b'" Then, in / mods-available / sqlcounter, I added: sqlcounter monthlytrafficcounter { sql_module_instance = sql #dialect = $ {modules.sql.dialect} dialect = "mysql" counter_name = Monthly-Traffic check_name = Max-Monthly-Traffic reply_name = Monthly-Traffic-Limit key = User-Name reset = monthly $ INCLUDE $ {modconfdir} / sql / counter / $ {dialect} / $ {.: instance} .conf } and enable it: # cd /etc/freeradius/3.0/mods-enabled ln -s ../mods-available/sqlcounter sqlcounter # nano /etc/freeradius/3.0/sites-enabled/default authorize { ... sql # check monthly usage limit monthlytrafficcounter ... } and restart freeradius Could you help me to find out why it does not work?
