Nmap for Windows under command-line use

Work on it, whether in development or operations, when testing some system service ports, there are always TCP or UDP two protocols. As is known to all, TCP service ports can be remotely tested via Telnet, while UDP ports, in general, use Nmap, whether in Linux or Windows environments.

Nmap software under Windows also has a graphical interface with command-line mode, but most people use skilled people, more inclined to command-line mode, because the operation is simple and fast.

After the installation is complete on Windows, run the open graphical interface directly

How do I use Command mode?

1, direct CMD,CD to the installation directory, the implementation of NMAP command

2. Modify environment variables so that you can execute nmap at any time

On my Computer-Properties-advanced-environment variable environment Variables-system Variables-path

Path modification: Add the Full installation directory path, separated by semicolons.

%systemroot%\system32;%systemroot%;%systemroot%\system32\wbem;%systemroot%\system32\windowspowershell\v1.0\; E:\software\BIND9.11.1.x64; C:\Program Files (x86) \nmap;

Test command line scan UDP port

Open Xshell or cmd

Scan the DNS 114.114.114.114 UDP 53 port, the result is the port state is closed

Scan DNS 8.8.8.8 UDP 53 port, the result is the port state is up

Of course, you can also scan the TCP port of the site
