vi /etc/suricata/capture-filter.bpf not (host 10.200.1.5 and ip and tcp and port 8480)

cp -pi /etc/init.d/suricata /etc/init.d/suricata.dist chmod -x /etc/init.d/suricata.dist vi /etc/init.d/suricata SURICATA_OPTIONS=" -c $SURCONF --pidfile $PIDFILE $LISTEN_OPTIONS -D -vvv $USER_SWITCH -F /etc/suricata/capture-filter.bpf" systemctl daemon-reload systemctl restart suricata
