Using Nmap Kali for Network Scanning
Now that you’ve learned the basics of Nmap Kali, it’s time to use it for network scanning. Here are some essential steps to follow:
- Scan the network:
sudo nmap -sS -P0 -oN / - Scan a specific host:
sudo nmap -sS -P0 -oN 192.168.1.100 - Scan a specific port range:
sudo nmap -sS -P0 -oN 1-1024 - Scan a specific scan type:
sudo nmap -sT -P0 -oN / - Scan a specific scan depth:
sudo nmap -sP -oN / - Scan a specific scan timeout:
sudo nmap -sT -P0 -oN 10
Using Nmap Kali for Port Scanning
Once you’ve scanned the network, it’s time to use Nmap Kali for port scanning. Here are some essential steps to follow:
- Scan a specific host:
sudo nmap -sS -P0 -oN 192.168.1.100 - Scan a specific port range:
sudo nmap -sS -P0 -oN 1-1024 - Scan a specific scan type:
sudo nmap -sT -P0 -oN / - Scan a specific scan depth:
sudo nmap -sP -oN / - Scan a specific scan timeout:
sudo nmap -sT -P0 -oN 10
Using Nmap Kali for OS Detection
Once you’ve scanned the network, it’s time to use Nmap Kali for OS detection. Here are some essential steps to follow:
- Scan a specific host:
sudo nmap -sS -P0 -oN 192.168.1.100 - Scan a specific port range:
sudo nmap -sS -P0 -oN 1-1024 - Scan a specific scan type:
sudo nmap -sT -P0 -oN / - Scan a specific scan depth:
sudo nmap -sP -oN / - Scan a specific scan timeout:
sudo nmap -sT -P0 -oN 10
Using Nmap Kali for Vulnerability Scanning
Once you’ve scanned the network, it’s time to use Nmap Kali for vulnerability scanning. Here are some essential steps to follow:
- Scan a specific host:
sudo nmap -sS -P0 -oN 192.168.1.100 - Scan a specific port range:
sudo nmap -sS -P0 -oN 1-1024 - Scan a specific scan type:
sudo nmap -sT -P0 -oN / - Scan a specific scan depth:
sudo nmap -sP -oN / - Scan a specific scan timeout:
sudo nmap -sT -P0 -oN 10
