Question

我正在阅读暴力python一书，并使用github中的一些示例在python 3中编写代码。对于大多数端口，一切都进行得很好，但是在端口扫描程序上，我正在运行此重复的错误模块“套接字”没有属性“ SOCKET_STREAM”。我尝试搜索此示例，但是我看到的大多数示例都不相关。

尽管我不认为这是操作系统问题，但我曾尝试在Windows和Linux上对此进行编码。

#!/bin/bash/python 3.7
import argparse
import binascii
import socket
import threading

screen_lock = threading.Semaphore(value=1)


def conn_scan(target_host, target_port):
    conn_skt = socket.socket(socket.AF_INET, socket.SOCKET_STREAM)
    error = conn_skt.connect_ex(target_host, target_port)
    screen_lock.aquire()
    if not error:
        print("[*] %d tcp open, " % target_port)
    else:
        print("[*] %d tcp closed." % target_port)

    screen_lock.release()
    conn_skt.close()


def ban_scan(target_host, target_port):
    try:
        conn_skt = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        conn_skt.connect(target_host, target_port)
        conn_skt.send(b'ViolentPython3\r\n')
        conn_skt.recv(100)
        screen_lock.aquire()
        print("[+] %d/tcp open " % target_port)
    except Exception:
        print("[-] %d/tcp closed " % target_port)
    finally:
        screen_lock.release()
        conn_skt.close()


def initiate_scan(target_host, target_ports):
    try:
        target_IP = socket.gethostbyname(target_host)
    except Exception:
        print("[-] Cannot resolve '%s': Unknown host" % target_host)
        return
    try:
        target_name = socket.gethostbyaddr(target_IP)
        print("\n[+] Scan results for: " + target_name[0])
    except Exception:
        print("\n[+] Scan results for : " + target_IP)

    socket.setdefaulttimeout(1)
    for target_port in target_ports:
        print("Scanning port " + target_port)
        t = threading.Thread(target=conn_scan, args=(target_host, int(target_port)))
        t.start()


def main():
    parser = argparse.ArgumentParser()
    parser.add_argument('-H', '--host', help='specify target host')
    parser.add_argument('-P', '--port', help='specify target ports separated by comma')
    args = parser.parse_args()

    target_host = args.host
    target_ports = str(args.port).split(',')

    if(target_host is None) | (target_ports[0] is None):
        parser.print_help()
        exit(0)
    initiate_scan(target_host, target_ports)


if __name__ == '__main__':
    main()

应显示端口扫描的输出

端口扫描器显示模块错误，这与什么有关？
