How to Manage Active Network Connections

sudo ss -K src :60032 dst $IP

sudo ss -K dst $IP dport = $PORT

If ss -K isn't available on your system, you can use tcpkill. It works by sniffing the traffic and injecting "RST" (reset) packets to tear down the connection.

sudo apt install dnsiff
sudo tcpkill -i $IFACE_ host $IP
