Hello family
I’m stuck on mu enumeration all ports are filtered I can’t move on, please does anyone has the hint, how I can move forward instead of stacking with nmap?

Ensure the connectivity is there and the target is reachable. Also the ICMP might be blocked. Try to Perform the Nmap scan using the `-Pn` switch. This will disable the ICMP scan.
eg: `nmap -Pn -sS 1.2.3.4`

If you are not already then try running nmap with elevated privileges using sudo. I had a similar issue and it was not until I did this that the open ports were detected.

rightly @walsh.john-cbcba15b1 pointed out, Other than the TCP connect scan, mostly all nmap scan requires root privileges.
