Question

Can You Provide an Example of a Simple Port Scanner in Python?

Answer 1

Sure, here's a basic example of a port scanner in Python using the socket library:

import socket

target = "example.com"
ports = [80, 443, 8080, 22]

def scan_port(host, port):
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock.settimeout(1)
    result = sock.connect_ex((host, port))
    sock.close()
    return result

for port in ports:
    if scan_port(target, port) == 0:
        print(f"Port {port} is open")
    else:
        print(f"Port {port} is closed")
