The NPCAP library is a library for network packet capture and analysis on Windows platforms. It is a fork of the WinPcap library, developed by the Nmap development team and used in the Nmap software. Like WinPcap, the NPCAP library provides APIs that allow developers to easily capture and process network packets in their applications. […]

Netty practice — Netty handles sticky packet unpacking
TCP packet sticking/unpacking TCP processes data in a streaming manner. Unpacking: A complete data packet may be split into multiple packets by TCP for sending. Sticky packets: TCP may stick multiple small packets into one large data packet. Introduce dependency packages: <dependency> <groupId>io.netty</groupId> <artifactId>netty-all</artifactId> <version>4.1.29.Final</version> </dependency> Example of sticky package unpacking: Server EchoServer: /** * […]

Burp Suite packet capture tool installation, operating environment configuration
1. Foreword BurpSuite is a software that does not require installation. You can start it directly from the command line after downloading the configuration. However, Burp Suite is developed in JAVA language, and its runtime depends on JRE, so the JAVA runnable environment needs to be installed in advance. Make a summary and record after […]

21.3 Python uses DPKT to analyze data packets
The dpkt project is a Python module, mainly used to parse and operate network data packets. It can handle a variety of protocols, such as TCP, UDP, IP, etc., and provides some common network operation functions, such as calculation verification And, parse DNS packets, etc. Due to its simplicity and ease of use, dpkt is […]
Why can’t I catch Baidu’s data packets?
Recently, a reader asked about a strange thing. He said that he wanted to grab a data packet of baidu.com and experience the fun of reading the packet. But I found “Can’t catch“, which is a bit strange. Let me restore his steps. First, use the ping command to get which IP will be requested […]
