替换netcat使用kali linux

标签: python-2.7

我买了这本名为" blackhat python"因为我专注于网络安全和分析,并且为了安全性好我相信你应该知道黑客黑客的想法,所以我一直在关注书中的代码示例,由于某种原因我无法弄清楚,这是错误我收到了,

  [*] Exception! Exiting.
     Traceback (most recent call last):
      File "bhnet.py", line 59, in <module>
      client.close()
       AttributeError: 'module' object has no attribute 'close'

下面是我所遵循的书中的代码。有没有人可以告诉我发生了什么,并可能解释它,因为我还在学习,而不是专家,也许这将有助于我更多地了解它以及我如何解决它,谢谢先进。 / p>
