We frequently encounter individuals who cannot use something<\/em> from their server or desktop — but their IT group has Windows locked down so they cannot just telnet to the destination on the port and check if it’s connecting. Windows doesn’t have a whole lot of useful tools of its own. Fortunately, I’ve found that nmap.org publishes a local install zip file for Windows.<\/p>\n

Download latest Win32 zip file from https:\/\/nmap.org\/dist\/<\/a> — on 8\/8\/2023, that is https:\/\/nmap.org\/dist\/nmap-7.92-win32.zip<\/a><\/p>\n

 <\/p>\n

Extract the zip file contents somewhere (I use tmp, right in downloads works, whatever)
\nOpen command prompt and change directory (cd) into the folder where nmap was extracted<\/em> — e.g. cd \/d c:\\tmp\\nmap-7.92<\/p>\n

— A quick trick for opening a command prompt to a directory location: If you have a file explorer window open to the location, click into the header where the file path is shown and remove the text that appears there<\/p>\n

\"\"<\/a><\/p>\n

Type cmd<\/em> and hit enter<\/p>\n

\"\"<\/a><\/p>\n

And voila — a command prompt opened to the same location you were viewing<\/p>\n

\"\"<\/a><\/p>\n

In the command prompt, run an map command to test a specific port (-p) and host. Since some hosts do not return ICMP requests, I also include -P0 instructing nmap not<\/em> to attempt pinging the host first. This example verifies we have connectivity to google.com on port 443 (https)<\/p>\n
