When I run this scan nmap -sn 192.168.9.0/25 nmap pings the address range (expected result ) but it also sends syn packets to tcp port 443 on each of the IP’s And it sends ack packets to port 80
-sn doesn't mean "ping scan"; it means "host discovery only." The default host discovery sends four probes: ICMP echo TCP SYN to port 443 TCP ACK to port 80 ICMP timestamp request If you only want ICMP echo, do -sn -PE. _______________________________________________ Sent through the dev mailing list https://nmap.org/mailman/listinfo/dev Archived at http://seclists.org/nmap-dev/
