Test Case #1
------------
dpkg-reconfigure and chose:
TCP, port 3330, IP: 10.108.97.11
root@clamav-jammy-sru:~# sudo systemctl restart clamav-daemon
root@clamav-jammy-sru:~# sudo ss -pln | grep 3330
root@clamav-jammy-sru:~# printf "PING\n" | nc 10.108.97.11 3330
root@clamav-jammy-sru:~# systemctl cat clamav-daemon.socket

[Socket]
ListenStream=/run/clamav/clamd.ctl
#ListenStream=1024
SocketUser=clamav
SocketGroup=clamav
RemoveOnStop=True
[Install]
WantedBy=sockets.target
Nothing is listening on the configured IP:port and changes are not
reflected in the socket file
Test Case #2
------------
root@clamav-jammy-sru:~# sudo dpkg-reconfigure clamav-daemon
# Set the socket to clamd-alt.ctl, socketgroup to clamav-user, socketmode to 777
root@clamav-jammy-sru:~# sudo systemctl restart clamav-daemon
