Question

我在计算机上设置了一个侦听端口4433的SSL服务器，我想进行某些测试并收集流量。我正试图用scapy做到这一点，但是，我无法收集任何流量

from scapy.all import *
import time
from threading import Thread, Event
import os

class Sniffer(Thread):
    def  __init__(self, host, interface=None):
        super().__init__()
        self.daemon = True
        self.socket = None
        self.filters = "dst port " + str(host)
        print(self.filters)
        self.interface = interface
        self.stop_sniffer = Event()
    def run(self):
        print("running")
        conf.L3listen= L3RawSocket
        self.socket = conf.L3listen(
            filter=self.filters
        )
        self.capture = sniff(
            filter='tcp and (port 4433 or port 4444)',
            opened_socket=self.socket,
            prn=self.print_packet,
            stop_filter=self.should_stop_sniffer#,
            #store=0
        )
    def join(self, timeout=None):
        self.stop_sniffer.set()
        super().join(timeout)

    def should_stop_sniffer(self, packet):
        return self.stop_sniffer.isSet()

    def print_packet(self, packet):
        print(packet)
    def write_packet(self):
        wrpcap("hi.pcap", self.capture)

sniff = Sniffer("4433")
sniff.start()
for i in range(100):
    os.system("wget -qO- https://localhost:4433 --no-check-certificate /dev/null")
sniff.join(5.0)
sniff.write_packet()

输出

Traceback (most recent call last):
  File "traffic_scapy.py", line 56, in <module>
    sniff.write_packet()
  File "traffic_scapy.py", line 48, in write_packet
    wrpcap("hi.pcap", self.capture)
AttributeError: 'Sniffer' object has no attribute 'capture'

在本地服务器上用scapy嗅探，未产生流量
