As most of us know, the Earth’s CO2 levels keep rising, which directly contributes to the melting of our pale blue dot’s icecaps. This is slowly but surely making it harder for our beloved polar bears to keep on living. So, it’s time for us information security professionals to help do our part. As we all know, every packet traveling over the Internet is processed by power hungry CPUs. By simply sending fewer packets, we can consume less electricity while still get our banner grabbing, and subsequently our work, done.
- Send a packet with the RST flag set, which means the port is closed and the host is not accepting connections on that port.
- Send a packet with the SYN and ACK flags set, which means the host is accepting the connection. The Operating System under which nmap runs doesn’t know anything about the outgoing SYN packet (as it was created in raw mode), and subsequently it will send back an RST packet as a reply.
