I'm running Kali in a VM (Windows 10 host) and using nmap to scan for open ports on a vulnerable mail server. Network settings are set to host-only for both machines. I know there are more ports open then what is being shown. However, these are the only ports found after performing the attached scan. I've also tried scanning all ports with -p- but my results are the same. Any idea why?

Thanks in advance for the help.

    Are you sure that the service / daemon is running, not firewalled and listening on all/external interfaces?

  • Use different scan variants: Varients also try using -Pn

Not shown: 997 filtered ports

Because the ports that are not shown are filtered and not closed, I would guess there is a host firewall blocking access to the other ports. Turn off Windows Firewall or allow access to the required ports and you will probably be able to see them.
