Incoming is a packet monitor designed to monitor SYN packets. Machines receive SYN packets when a remote machine is trying to initiate a TCP connection.
When a machine is listening on a port, it replies the machine sending the SYN packet with an aknowledgement ( ACK ) request. If the machine is not listening on a particular port, then the machine will reply with a reset ( RST ) request.
