修复scapy.all模块中的python错误

Question

当通过scapy编写网络扫描器时：

import scapy.all as scapy

arp = scapy.ARP(pdst='192.168.1.1/24')
broadcast = scapy.Ether(dst='ff:ff:ff:ff:ff:ff')

final_packet = broadcast/arp

answered , unanswered = scapy.srp(final_packet,timeout=1)
print(answered.summary())

然后我收到以下错误：

Traceback (most recent call last):
  File "network_scanner.py", line 8, in <module>
    answered , unanswered = scapy.srp(final_packet,timeout=1)
  File "/home/mohammad/.local/lib/python3.6/site-packages/scapy/sendrecv.py", line 504, in srp
    filter=filter, nofilter=nofilter, type=type)
  File "/home/mohammad/.local/lib/python3.6/site-packages/scapy/arch/linux.py", line 467, in __init__
    self.ins = socket.socket(socket.AF_PACKET, socket.SOCK_RAW, socket.htons(type))  # noqa: E501
  File "/usr/lib/python3.6/socket.py", line 144, in __init__
    _socket.socket.__init__(self, family, type, proto, fileno)
PermissionError: [Errno 1] Operation not permitted

如何修复它？

您应该以超级用户身份运行脚本。
