Scanning

Nmap aggressive full port scan

nmap -Pn -p- --min-rate 10000 <Target IP> -oN nmap-port

Nmap aggresive version scan

nmap -v -sT -sU -sC -A -O -T4 -p<ports> <Target IP> -oN nmap-version

• If you want to scan UDP scanning for ports you can use -sU switch

Alternate way (Using NetCat)

nc -zv <Target IP> 1-65535

• use u switch for UDP
