node.js - 在 Windows 上使用 nodejs 捕获数据包

Question

node.js v0.8.0 , XP / WIN7 (不是 Cygwin)

谷歌发现 node_pcap ( https://github.com/mranney/node_pcap )

但它只支持 osx 和 linux。

有没有适用于 windows 的模块？

谢谢。

Answer 1

如果你想要更跨平台的东西（例如通过 WinPcap 与 Windows 兼容），我写了cap一会儿：https ://github.com/mscdex/cap

Answer 2

我试图在 Windows 机器上捕获、解码和监视 AMF 请求，并提出了以下解决方案，用于使用node.js、edge.js和pcap.net 库捕获数据包。

确保您拥有正确的 node.js 版本（32 位或 64 位）以及 edge.js 的要求

还要确保更改/删除代码中第 64 行周围的数据包过滤器。

var edge = require('edge');

var PacketCap = edge.func('cs', function () {/*
    #r "PcapDotNet.Base.dll"
    #r "PcapDotNet.Core.dll"
    #r "PcapDotNet.Core.Extensions.dll"
    #r "PcapDotNet.Packets.dll"
    #r "System.Xml.dll"
    #r "System.Xml.Linq.dll"

    using System.Collections.Generic;
    using System.Linq;
    using PcapDotNet.Core;

    using PcapDotNet.Packets.Http;

    using System.Collections;

    async (dynamic data) => {
        var NodeOut = (Func<object,Task<object>>)data.NodeOut;
        IList<LivePacketDevice> allDevices = LivePacketDevice.AllLocalMachine;
        if (allDevices.Count == 0)
        {
            Console.WriteLine("No interfaces found! Make sure WinPcap is installed.");
        }

        // Print the list
        for (int i = 0; i != allDevices.Count; ++i)
        {
            LivePacketDevice device = allDevices[i];
            Console.Write((i + 1) + ". " + device.Name);
            if (device.Description != null)
                Console.WriteLine(" (" + device.Description + ")");
            else
                Console.WriteLine(" (No description available)");
        }

        int deviceIndex = 0;
        do
        {
            Console.WriteLine("Enter the interface number (1-" + allDevices.Count + "):");
            string deviceIndexString = Console.ReadLine();

                                                                        // 65536 guarantees that the whole packet will be captured on all the link layers

            // Retrieve the packets
