Probe into the scapy of network scan big kill device in Python
Recently experienced twisted blow, this network programming really do not understand, can not touch its internal logic, it seems that network programming is not so good to get. Fortunately, see the scapy, this network of Big kill device, let me a look on it, this is I
1. IntroductionRecently has been used to do traffic analysis, today the scapy part to do a summary.Python's scapy library can easily grab packets and parsing packages, helpless data, limited official examples, the Great God blog is rarely mentioned, after some attempts, summed up the following several usage so that everyone later use.2. Usage examples
InstallationAs a beginner, the first concern is how
This article describes how to use scapy to simulate packets in Python to implement arp attacks and dns amplification attacks. This article focuses on the use of scapy, for more information, see scapy, a powerful interactive data packet processing program written in python.
1. Foreword
If you only need to study the TCP stack behavior of Linux, just use Packetdrill to meet all my requirements. Packetdrill is what makes me want to be the TCP stack. Packetdrill simple manual for use.
However, the tragedy is that, in addition to studying the TCP stack behavior of Linux, but also need to study the TCP stack of Windows behavior, Windows is not open source, feel that there should be quite a few unknown pits.
To be able to reproduce some of the network behavior of Windows
Python scapy network sniffing1. Introduction
Scapy is a powerful third-party library for network sniffing. In terms of network sniffing, the previous blog post introduced the use of Raw Socket for network sniffing. However, Raw Socket is relatively low-layer and may not be easy to use and may differ in different systems.In terms of network traffic sniffing, some
executes, it will quickly loop through the packet and end with CTRL + C. Use the Inter option if you want to have a certain time interval between sending packets two times. sendp(Ether()/IP(dst= "www.baidu.com")/ICMP()/"XXX",iface="eth0",loop=1,inter=1)Indicates that a packet is sent every 1 seconds.2.3 Sending and receiving packets on level 2 and Level 3
Level 3

This article describes how to obtain the mac address of all hosts in the LAN using python scapy. For more information, see obtain the mac address of all hosts in the LAN using python scapy.

A. DescriptionUsing the scapy third-party library, write an ARP scan of a network segment to obtain the IP address and MAC address of the active host within that segment.Two. Analysis and Solutions
First, import the relevant modules from Scapy.
Ether ()/arp () constructs the ARP packet.
SRP1 () sends and receives ARP packets.
The code examples are as follows:#!/usr/bin/env

What's the Scapy module for?A: Scapy is a powerful interactive packet handler (written in Python). It can spoof or decode a large number of network protocol packets, can send, capture, match requests and reply packets and so on. It can easily handle some typical operations such as port scanning, tracerouting, probing, unit testing, attack or network Discovery (al
Scapy is a powerful interactive packet processor written by Python that can be used to send, sniff, parse, and forge network packets, often used in network attacks and tests.
This is done directly with Python's scapy.
Here is the ARP attack way, you can make ARP attack.
Copy Code code as follows:
#!/usr/bin/

Sniff (filter = "", iface = "any", prn = function, count = N)
The filter parameter allows us to specify a BPF (Wireshark type) filter for Scapy sniffing data packets, or leave it blank to sniff all data packets.
For example, sniffing all HTTP data packets and tcp port 80 BPF Filtering

with two hosts flooding.2. The host, A, and a are flooding the ARP Request. The attacker now has two host IP, MAC addresses, to start the attack.The attacker sends an ARP reply to Host B, sets the sender IP of this packet protocol header to the IP address of a, and the sender Mac is set as the attacker's own MAC address.3. When Host B receives the ARP reply, it updates its ARP table and changes the host A's entry (ip_a, mac_a) to (Ip_a, Mac_c).4. When Host B is sending a packet to host A, it en
Python uses the scapy library for ARP Spoofing1. Description
ARP spoofing, also known as ARP attack or ARP attack, is an attack technique against the Ethernet Address Resolution Protocol (ARP. This attack can allow attackers to obtain packets or even tamper with data packets on the LAN, and prevent a specific computer or all computers from connecting to the network. The first article to explore ARP spoofing
