Nmap performed: three IP addresses (3 hosts up) scanned in zero. 31 seconds the way it works… The process utilized by Nmap to accomplish TCP discovery employs an analogous underlying precept we mentioned while appearing TCP discovery with Scapy. Nmap sends a sequence of TCP ACK packets to arbitrary ports at the aim approach and makes an attempt to solicit an RST reaction as a sign of a reside procedure. The method utilized by Nmap to accomplish UDP discovery, even though, is a little bit diverse than the strategy we mentioned with Scapy. instead of in simple terms hoping on ICMP host-unreachable responses, which are inconsistent and/or blocked, Nmap additionally plays host discovery through providing service-specific requests to unique ports in an try and solicit a reaction.
