i use the following command to scan a webserver,
nmap -A -T4 -F -PN x.x.x.x
it doesnt show port 80 is open
i run wireshark and open browser and type url, it does shows that my pc is connecting to port 80 of x.x.x.x webserver
my question is whats the nmap command to scan all the open ports in the webserver.
