Nmap Simulation Project

Overview

This project simulates basic functionalities of the popular nmap tool using a custom-built server and client application. The server allows clients to perform network operations such as pinging a host, checking open ports, and testing response times to ports.

The simulation includes:

• Ping using ICMP to check if a host is online.
• Port Scanning to check if specific ports on a host are open.
• Response Time to measure how quickly a port responds.

Features

• /ping <hostname/IP>: Sends an ICMP ping request to check if a host is online.
• /port <hostname/IP> <start_port> <end_port> <#num_requests>: Scans a range of ports to check if they are open.
• /res_time <hostname/IP> <#num_requests>: Measures the response time of a specific port.
• /GET <user_ID>: Retrieves information about a specific user.
• /POST <user_name> <user_age>: Adds a new user to the server.

Example Commands

• Ping a host:

  /ping 192.168.1.1
  /ping google.com

• Check open ports:

  /port 192.168.1.1 22 80 5
  /port google.com 22 80 5

• Check response time for a port:

  /res_time 192.168.1.1 80 3
  /res_time google.com 80 3

• Get user information:

  /GET user1

• Add new user:

  /POST "John Doe" 28
