Hi If I run the command nmap -p 445 1.2.3.4 what host detection should nmap use to decide if the host is up before it checks the ports? I would have assumed that one of the checks would be to ping it but if you look at the attached screenshot, I ping the host and get a reply, nmap then says that it is down, I ping again, still have replies, I then scan with -P0 and I get the response I'm expecting, that the port is open. Why do I have to force the host to be up? Robin [image: nmap_no_ping.png]
