python实现全端口扫描

import socket
from concurrent.futures import ThreadPoolExecutor# 扫描指定 IP 地址的端口
def scan_port(ip, port):with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:s.settimeout(0.5)  # 设置超时时间result = s.connect_ex((ip, port))  # 尝试连接if result == 0:print(f'Port {port} is open')# else:#     print(f'Port {port} is closed')def scan_ports(ip):with ThreadPoolExecutor(max_workers=100) as executor:# 使用并发扫描for port in range(1, 65536):executor.submit(scan_port, ip, port)if __name__ == '__main__':target_ip = input("Enter the IP address to scan: ")print(f"Scanning {target_ip} for open ports...")scan_ports(target_ip)
