当我试图回答自己的dns请求时，为什么会出现这个错误

Question

import scapy.all as scapy
p = scapy.DNS(qd=scapy.DNSQR(qname='www.example.com'), an=scapy.DNSRR(rrname='127.0.0.1'))
scapy.send(p)

结果：

Traceback (most recent call last):
File "/home/kali/PROJECTS/server.py", line 3, in <module>
scapy.send(p)
File "/usr/lib/python3/dist-packages/scapy/sendrecv.py", line 425, in send
return _send(

results = __gen_send(socket, x, inter=inter, loop=loop,

s.send(p)

self.outs.bind(sdto)

Answer 1

您必须指定目标地址和端口。

p = scapy.IP(dst='127.0.0.1') / scapy.UDP(sport=53, dport = client_port) / scapy.DNS(qd=scapy.DNSQR(qname='www.example.com'), an=scapy.DNSRR(rrname='127.0.0.1'))
