Why when I scan the ports of a specific IP using Nmap? It gives me "all ports are filtered."


When I run an Nmap scan on any website it , it shows me that all ports are filtered . Sometimes some ports appear (maximum 2) , but when I attempt to perform an attack on it , the ports suddenly vanish and the filtered ports message pops up again. Any explanations concerning that?

Many possibilities, but you don't post any details that would let us speculate past "Whomever you're scanning has decent network security". You don't tell us version/distro of Linux, what you're goal(s) are, the environment you're running this in, etc. We cannot guess.

Read the "Question Guidelines" link in my posting signature.

If you don't know the test target, it sounds suspicious...

So you're well aware that Kali is not for 'newbie' users (where you posted this thread), and that it's for advanced users with a background in network/systems security, right? Since you fit that description (right?), you should know...

...how to diagnose where such issues lie. What kind of diagnostics have you run so far? What is your 'target' (internet? local?) Your connection parameters; do you run through a firewall or not? What is between you and your target?
