Overview

This node performs a network discovery scan using the nmap tool with a SYN scan (-sS) to identify devices and open ports on a specified network range or host IP. It is useful for network administrators or security professionals who want to map out active devices and their open ports within a network segment. For example, scanning a local subnet to find all connected devices and the services they expose.

Use Case Examples

  1. Scan the 192.168.0.0/24 subnet to discover all active devices and their open ports using a SYN scan.
  2. Use the node to perform a network discovery on a specific IP range with options to control scan aggressiveness and port checking.

Properties

Name Meaning
Target Network Range / Host / IP Defines the target network range, host, or IP address to scan, e.g., 192.168.0.0/24.
Options Collection of optional parameters to customize the scan behavior.

Output

JSON

json - Field containing parsed port and device discovery data from the scan, where is user-defined (default 'ports').

Dependencies

  • Requires nmap command-line tool installed and accessible in the environment.
  • Requires sudo password credential to execute nmap with elevated privileges.

Troubleshooting

  • Common issues include incorrect sudo password causing command failure; ensure the password is correct and has necessary permissions.
  • If nmap is not installed or not in the system PATH, the scan will fail; verify nmap installation.
  • Invalid network range or IP input can cause scan errors; validate the target input format.
  • Timeouts or network restrictions may cause incomplete scan results; check network accessibility and firewall settings.
