Port Scan using nmap

To port scan a service via nmap use following steps:

1. Login into Kali Linux
2. Get root terminal (sudo su -)
3. Run nmap on target on standard ports (approx 1000) use:

   nmap -v -A <FQDN-or-IP>

4. To scan each and every port use:

   nmap -v -A -p1-65535 <FQDN-or-IP>

5. To see more options type 'nmap' and press enter

Scan live hosts using nmap

If static IP addressing is used then we can scan for free IPs using:

   For example
