使用SCAPY时出现的问题 (许可被拒绝)

Question

我想用python3做一个简单的网络扫描器，可以扫描整个局域网的设备。这时，我听说了Scapy。然而，每当我尝试运行我的程序时，它都会返回一个错误信息"PermissionError.[Errno 13]Permission denied [Errno 13]拒绝许可"

这是我的代码。

import scapy.all as scapy


def scan(ip):

  scapy.arping(ip)

scan("192.168.43.1")

如果你们能解决这个问题，会对我有很大帮助。谢谢你的阅读。

我相信这个方法 scapy.arping() 打开原始套接字。尝试以root用户身份运行 sudo.
