Enable SQLCounter FreeRadius

QLCounter Is a module that is used to record user statistics that are entered and written in the database, such as recording the time a user logs in, transfers data, and sessions.

For example activating the Access Period and Quota Limit

sudo nano /etc/freeradius/3.0/mods-available/sqlcounter

Add code

sqlcounter accessperiod {
sql_module_instance = sql
dialect = ${modules.sql.dialect}

counter_name = Max-Access-Period-Time
check_name = Access-Period
key = User-Name
reset = never

$INCLUDE ${modconfdir}/sql/counter/${dialect}/${.:instance}.conf
}

sqlcounter quotalimit {
sql_module_instance = sql
dialect = ${modules.sql.dialect}

counter_name = Max-Volume
check_name = Max-Data
reply_name = Mikrotik-Total-Limit
key = User-Name
reset = never

$INCLUDE ${modconfdir}/sql/counter/${dialect}/${.:instance}.conf
}

Create file accessperiod.conf

-- MySQL --
sudo nano /etc/freeradius/3.0/mods-config/sql/counter/mysql/accessperiod.conf

-- Add Query --
query = "\
SELECT UNIX_TIMESTAMP() - UNIX_TIMESTAMP(AcctStartTime) \
FROM radacct \
WHERE UserName='%{${key}}' \
ORDER BY AcctStartTime LIMIT 1"

-- PqSQL --
sudo nano /etc/freeradius/3.0/mods-config/sql/counter/postgresql/accessperiod.conf

-- Add Query --
query = "\
SELECT date_part('epoch',CURRENT_TIMESTAMP)::int - date_part('epoch', AcctStartTime)::int \
FROM radacct \
WHERE UserName='%{${key}}' \
ORDER BY AcctStartTime LIMIT 1"

Create file quotalimit.conf

-- MySQL --
sudo nano /etc/freeradius/3.0/mods-config/sql/counter/mysql/quotalimit.conf

-- Add Code --
query = "\
SELECT (SUM(acctinputoctets) + SUM(acctoutputoctets)) \
FROM radacct \
WHERE UserName='%{${key}}'"

-- PgSQL --
sudo nano /etc/freeradius/3.0/mods-config/sql/counter/postgresql/quotalimit.conf

-- Add Query --
query = "\
SELECT (SUM(acctinputoctets) + SUM(acctoutputoctets)) \
FROM radacct \
WHERE UserName='%{${key}}'"

Edit file default

sudo nano /etc/freeradius/3.0/sites-enabled/default

Add code in the authorize{} section

authorize {
expiration
logintime
quotalimit
dailycounter
accessperiod
monthlycounter
noresetcounter
}

Enable sqlcounter

cd /etc/freeradius/3.0/mods-enabled
sudo ln -s ../mods-available/sqlcounter sqlcounter

If the above command doesn't work

sudo nano /etc/freeradius/3.0/radiusd.conf
-- Add --
$INCLUDE mods-enabled/ 
$INCLUDE mods-available/sqlcounter
