sorry I'm a very newbie in freeradius, and I try to create a VPN server using squid and check user sessions using freeradius. everything is ok, except the accounting and checking the sessions.
my goal is to limit any usernames session to only can connect with 2 devices at the same time
I configured a radius server on a server and configured a squid server on another VPS
my configuration details
Servers OS : Centos 7
Freeradius : Version 3.0.13
Squid : Version 3.5.20
my squid.conf Server Configuration

#
# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed

# And finally deny all other access to this proxy

# Squid normally listens to port 3128

# Uncomment and adjust the following to add a disk cache directory.

# Leave coredumps in the first cache dir

#
# Add any of your own refresh_pattern entries above these.

refresh_pattern ^gopher: 1440 0% 1440

refresh_pattern . 0 20% 4320
it's connected and check the username/password with the radius server but the issue is the accounting didn't work
I enable SQL module at mods-enables and enable SQL in accounting section of sites-enables/default but radacct didn't updated and its always empty
based on some search I enable read-groups in SQL module and set Acct-Interim-Interval := 60 for the group where the users are and its sent with the Access-Accept to squid server and accounting still didn't worked and nothing happened
Sent Access-Accept Id 34 from xx.xx.82.205:1812 to xx.xx.144.172:47574 length 0
(2) Acct-Interim-Interval = 60
please can somebody clearly explain to me how can in enable Accounting and control sessions on freeradius
thanks for your helps
