### How to Install Nmap and Use Nmap for Scanning
|
|
|
|
1. **Update your system:**
|
|
```bash
|
|
sudo apt-get update
|
|
```
|
|
|
|
2. **Install Nmap:**
|
|
```bash
|
|
sudo apt install nmap
|
|
```
|
|
|
|
3. **Scan a single IP address:**
|
|
```bash
|
|
nmap [your_IP]
|
|
```
|
|
|
|
4. **Scan multiple IP addresses:**
|
|
```bash
|
|
nmap [your_IP1,your_IP2]
|
|
```
|
|
|
|
5. **Scan a range of IP addresses:**
|
|
```bash
|
|
nmap [your_IP1-your_IP100]
|
|
```
|
|
|
|
6. **Scan targets from a text file:**
|
|
```bash
|
|
nmap -iL filename.txt
|
|
```
|
|
|
|
7. **Check for live systems:**
|
|
```bash
|
|
nmap -sn [your_IP]
|
|
```
|
|
|
|
8. **Ping sweep:**
|
|
```bash
|
|
nmap -sP [your_IP]
|
|
```
|
|
|
|
9. **If ICMP is blocked:**
|
|
```bash
|
|
nmap -PN [your_IP]
|
|
```
|
|
|
|
10. **Scan specific port:**
|
|
```bash
|
|
nmap -p [your_port] [your_IP]
|
|
```
|
|
If ICMP is blocked:
|
|
```bash
|
|
nmap -PN [your_IP] -p [your_port]
|
|
```
|
|
|
|
11. **Scan multiple ports:**
|
|
```bash
|
|
nmap -p [port1,port2,port3-port6] [your_IP]
|
|
```
|
|
|
|
12. **Specify protocol:**
|
|
```bash
|
|
nmap -p http,https,ftp [your_IP]
|
|
```
|
|
|
|
13. **Scan TCP ports:**
|
|
```bash
|
|
nmap -p T:[port,port2] [your_IP]
|
|
```
|
|
|
|
14. **Get more information:**
|
|
```bash
|
|
nmap -p [your_port] -sV [your_IP]
|
|
```
|
|
|
|
15. **Detect operating system:**
|
|
```bash
|
|
nmap -O [your_IP] -p [your_port]
|
|
```
|
|
|
|
16. **Fast scan (top 100 ports):**
|
|
```bash
|
|
nmap -F [your_IP]
|
|
```
|
|
|
|
17. **Aggressive scan:**
|
|
```bash
|
|
nmap -A [your_IP] -p [your_port]
|
|
```
|
|
|
|
18. **Whois lookup:**
|
|
```bash
|
|
nmap -p [your_port] --script whois-ip [your_IP_or_domain]
|
|
```
|
|
|
|
19. **IP geolocation:**
|
|
```bash
|
|
nmap -p [your_port] --script ip-geolocation-* [IP]
|
|
```
|
|
|
|
20. **Detect Web Application Firewall (WAF):**
|
|
```bash
|
|
nmap -p [your_port] --script http-waf-detect [your_domain]
|
|
```
|
|
|
|
21. **Save results to a text file:**
|
|
```bash
|
|
nmap -Pn -p [your_port] [your_IP] -oN your_filename.txt
|
|
```
|
|
|
|
22. **Save results to an XML file:**
|
|
```bash
|
|
nmap -Pn -p [your_port] [your_IP] -oX filename.xml
|
|
```
|
|
|
|
23. **Save results to a grepable file:**
|
|
```bash
|
|
nmap -Pn -p [your_port] [your_IP] -oG filename.gnmap
|
|
```
|
|
|
|
24. **Save results to all formats:**
|
|
```bash
|
|
nmap -Pn -p [your_port] [your_IP] -oA filename
|
|
```
|
|
|
|
25. **Scan top ports:**
|
|
```bash
|
|
nmap --top-ports [number] [your_domain]
|
|
```
|
|
|
|
26. **Scan top ports and show open ones:**
|
|
```bash
|
|
nmap --top-ports [number] [your_domain] --open
|
|
```
|
|
|
|
27. **Check for open ports using different scan types:**
|
|
```bash
|
|
nmap -sT [your_IP] # TCP Scan
|
|
nmap -sS [your_IP] # SYN Scan
|
|
nmap -sX [your_IP] # XMAS Scan
|
|
nmap -sF [your_IP] # FIN Scan
|
|
nmap -sN [your_IP] # Null Scan
|
|
```
