Network scanning ( Ethical Hacking ) using python

 Here is an example of a simple Python program that can be used for ethical hacking:

python
import socket

def scan_port(target_host, target_port):
    try:
        # Create a TCP socket
        socket_obj = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        # Set a 3-second timeout
        socket.setdefaulttimeout(3)
        # Connect to the target host
        socket_obj.connect((target_host, target_port))
        # Print an open port message
        print(f"[+] Port {target_port} is open")
        # Close the socket connection
        socket_obj.close()
    except socket.error:
        # Print a closed port message
        print(f"[-] Port {target_port} is closed")

def main():
    # Get the target host and port from the user
    target_host = input("Enter the target host: ")
    target_port = int(input("Enter the target port: "))
    # Call the scan_port function
    scan_port(target_host, target_port)

if __name__ == "__main__":
    main()

This program allows you to input a target host and port, and then it attempts to connect to that port on the target host using a TCP socket. If the connection is successful, it prints a message indicating that the port is open. If the connection fails or times out, it prints a message indicating that the port is closed.

Note that this example is a very basic demonstration of network scanning, which is one aspect of ethical hacking. Ethical hacking encompasses a wide range of techniques and tools, and it is important to have proper authorization and use these techniques responsibly and legally.
