just get rid of -p$ports. I’ve noticed the tutorials kinda suck a little bit. They point you in the right direction but there very vague and leave you wanting more

Do i need to use to write -Pn to the command?

6

Because it says that host seems to be down

7

can you ping it?

8

that’s reply what i got : PING 10.10.10.27 (10.10.10.27) 56(84) bytes of data.

I’ve noticed if you dont type out

ports=$(nmap -p- --min-rate=1000 -T4 10.10.10.27 | grep [1] | cut -d ‘/’ -f 1 | tr ‘\n’ ‘,’ | sed s/,$//)

It will not run the base nmap scan.

Hope this helps.
