Magenta Systems Internet Packet Monitoring Components are a set of Delphi components designed to capture and monitor internet packets using either raw sockets or the WinPcap device driver. Hardware permitting, ethernet packets may be captured and interpreted, and statistics maintained about the traffic. Uses of packet monitoring include totalling internet traffic by IP address and service, monitoring external or internal IP addresses and services accessed, network diagnostics, and many other applications. The component includes two demonstration applications, one that displays raw packets, the other that totals internet traffic. The components include various filters to reduce the number of packets that need to be processed, by allowing specific IP addresses to be ignored, LAN mask to ignore local traffic, and ignore non-IP traffic such as ARP.
MPEG TS Utils application provides the user with a visual representation of the multiplexed stream structure of MPEG-2 Transport Streams (ISO/IEC 13818-1). The application allows the user to investigate the basic transport stream packets with their fields. The application also allows the user to manipulate with transport streams by filtering specified PIDs and exporting to file, demultiplexing to PES and ES streams, converting multi-program TS to single-program TS.
Capturing low-level network data can be hard in Java, but it s certainly not impossible
If you want to capture network packets in your Java program, you ll need a little help because no parts of the core Java APIAPI give access to low-level network
The simulator GUI is started with command ui_start in Matlab command window.
WLAN simulation starts by clicking the Start Simulation button in the GUI window.
WLAN simulation can be terminated, before set number of packets have been reached by pressing control-C .
This designs demonstrates how to use the Ethernet port using a Nios II system on the DE2 board. It sends packets, and using a loopback Ethernet cable, it ll receive the same packets which are then displayed. It also works if the board is connected to another packet source.
TinyRadius is a simple, small and fast Java Radius library capable of
sending and receiving Radius packets of all types. It is released
under the terms of the LGPL.
The main file in this list of programs is "vblast.m". Type "help vblast" on the command line for details.Study the coding
by stepping through the program. These programs require around 5000 packets for reasonable plotting accuracy.This has been
implemented for a 2x2 system. The reader can program other variations.
The program has been tested on MATLAB version 6.0 and above with signal processing toolbox and communication toolbox options.
The iputils package contains ping, a basic networking tool. The ping command sends a series of ICMP protocol ECHO_REQUEST packets to as pecified network host and can tell you if that machine is alive and receiving network traffic.ipv6calc is a small utility which formats and calculates IPv6 addresses in different ways. It extends the existing address detection on IPv6 initscript setup or make life easier in adding reverse IPv6 zones to DNSor using in DNS queries like nslookup -q=ANY ipv6calc -r 3ffe:400:100:f101::1/48`
/*
Here s a small IPv4 example: it asks for a portbase and a destination and
starts sending packets to that destination.
這個IPv4版的例子：它要求portbase(本地端口)與destination （目的端口）然后發送消息
同時還監聽消息。
例子測試一：
啟動一個運行實例，本地地址與目標地址用同一個端口8888
例子測試二：
啟動兩個運行實例，本地地址與目標地址用不同的端口（它要求是偶數端口號）
兩個實例互發
例子的中文解釋都由hanyuejun添加，有任何疑問請發hanyuejun2006@163.com

Libnet is a generic networking API that provides access to several protocols. It is not designed as a all in one solution to networking. Currently many features that are common in some network protocols are not available with Libnet, such as streaming via TCP/IP. We feel that Libnet should not provide specific features that are possible in other protocols. If we restrict Libnet to the minimal needed to communicate (datagram/packets) then this allows it to support more interfaces. 很好的學習linux網絡變成的源碼
