EtherPeek-NX-2.1软件的基本使用方法

如何用EtherPeek NX抓取大量报文一、目的大部分的抓包软件都可以提供Capture功能，但通常是将报文放在内存中，只有在点击保存时，才会将内存中的文件写入到硬盘上，如果想要抓取大量报文，例如抓取一个大文件的传输过程，大部分软件都无能为力，因为缓存能力有限，这里介绍如何利用Ethereek NX 软件实现这一功能。

二、安装EtherPeek软件是一个通用软件，可以在网络上下载，通常需要注册码，可自行解决。

三、配置本次讲解用EtherPeek NX版本，即EtherPeek NX for Windows v2.1版本，其他版本大同小异。

1.打开软件：2.选取Capture菜单，初次使用时，菜单中仅有Start Capture可以选择，Capture Option是灰的，选取Start Option后，会自动切换到Capture Option对话窗口；3.在Capture Option的General标签下选取将Capture的报文保存在本地，还可以调整抓包的buffer的大小，默认是16384Kbytes即16M，最大可以设置为2061484即2G，但通常不支持这么大的虚拟内存；4.在Adapter里面选取抓包的网卡，对于多网卡而言，可选取其中一个，如果是单网卡可以直接使用默认的唯一网卡；5.Triggers可以设置抓包的触发条件；6.Filters可以为收到的报文设置一个过滤，只Capture过滤的报文；7.Statistics Output可以将统计数据已HTML的格式保存成report；8.Performance可以查看启用和取消部分性能统计；9.点击确认，就开始Capture报文，这些报文会在抓满Buffer后，以文件的形式存在指定的路径中，如果报文非常多，那就保存很多文件，文件名以本机的抓包起始时间命令。

注意：1.上述方式可以抓取大量的数据报文，但前提是抓包的PC机性能需要高于发送和接收的设备，因为抓包的PC需要通过EtherPeek抓到报文后，还要写入硬盘，写入硬盘的速率太低会导致写入时间太长，在写入期间的数据报文是不会被抓取的；2.EtherPeek中的抓包buffer不宜设置过大，因为文件太大，PC系统在写入硬盘时，耗时太长，同样存在写入期间的数据报文无法抓取的情况；。

EtherScope ™nXGPortable Network ExpertDATA SHEETThe EtherScope nXG has two sets of native Wi-Fi network interfaces: a 4x4 adapter that scan and test Wi-Fi networks, and a 1x1 adapter for remote control connection and testing. Both interfaces support 802.11a/b/g/n/ac and can show analysis of utilization and status of Wi-Fi channels, SSIDs, BSSIDs, access points, client devices, and interferers. The EtherScope nXG provides visibility of Wi-Fi 6 devices.The EtherScope nXG has two Ethernet ports. The main test RJ-45 port supports Multi-Gig networks from 10/100/1000Mbps to 2.5/5/10G to verify link speed and duplex advertised and connected. It can request and verify PoE power under load from up to 90W PSE’s. Alternatively, it can interface to fiber networks via single/multi-mode SFP+ to test 1/10Gbps fiber-based Ethernet. The second RJ-45 management port connects to 10/100/1000Mbps Ethernet for remote control, and conducts network scanning and tests where needed. It is also the port for cable testing.The EtherScope nXG has built-in Bluetooth v5/BLE and USB interfaces to discover and Key FeaturesNEWUSB-AMain Ethernet Test Ports (RJ-45 & SFP)Cable Test & ManagementPortsUSB-CThe EtherScope nXG can stress critical network links, such as switch ports to servers/storage/Wi-Fi access points, uplinks or WAN links, with up to four simultaneous data streams at up to 10G line-rate. It verifies the link’s compliance to service level agreements (SLA) based on throughput, packet loss, delay and jitter against peers such as EtherScope nXG(s), OneTouch™ 10G(s), OptiView® XG(s) or a software reflector agent(s).The EtherScope nXG uses the popular iPerf v3 network test algorithm to test against the NetAlly Test Accessory. It determines TCP or UDP application throughput through its Wi-Fi or wired interfaces.Settings for data streams and thresholds for VoIP or video service can be stored and recalled where needed, saving configuration time.For key servers/services in the cloud or Internet, engineers can pre-define tests and thresholds to verify their connectivity and performance using ping, TCP connect, HTTP, or FTP. Continuous testing with response time measurements is available to verify consistency and identify intermittent issues. These tests can be easily recalled by field technicians to reduce configuration time or mistakes, to get more done faster.EtherScope nXG OneTouch™OptiView® XGWindows-basedSo ware AgentLinkRunner® AT LinkRunner G2Test AccessoryEtherScope nXGPEERS REFLECTORS bi-directionalround-tripLINE RATETEST IPERF TEST EthernetPerformance test with up to 4 streams and 4 end pointsFrame loss, jitter, and latency chartediPerf throughput test with TCP or UDP frames HTTP test against awebserver10G copper/fiber wired and Wi-Fi performance testsfor critical links and key devicesThe EtherScope nXG automatically discovers your network through its dual set of Wi-Fi and Ethernet test interfaces immediately upon power-up. The discovery provides quick security and health audits of the network devices across multiple VLANs and all Wi-Fi channels.Devices are classified and correlated to provide complete visibility of their name, network addresses, VLAN, SSID, device type, and whereavailable, traffic statistics. Discovery results can be directly uploaded to thecomplimentary Link-Live Cloud Service for storage or converted to CSV/PDFfiles as documentation.The EtherScope correlates the discovery result from the wired and Wi-Fi networks so that it is possible to show the name and IP address of Wi-Fi devices connected to the network. EtherScope nXG makes it easy to discover the actual identity of a Wi-Fi device while most other Wi-Fi tools only show the MAC address.EtherScope nXG’s discovery can be enriched by accessing SNMP MIBsof infrastructure devices. It shows details such as device configuration summary, interface configuration and traffic detail, SSIDs supported by WLAN Controllers, and devices directly connected to switches. Community strings entered are concealed from view.Discover possible security risks caused by users and others: 2nd DHCP offers indicating possible rogue servers, APs with different security schemes, unknown switches granting access to multiple devices, rogue Wi-Fi devices probing the network, and hidden SSIDs.The EtherScope nXG discovery automatically detects problems. It shows possible cause(s) for each problem detected, and it has integratedtroubleshooting tools to investigate further to get to root cause.Auditing and documenting network security andhealthWi-Fi Device shown with name & IP address Filters available to narrow down to devices of interestAdditional filters available for device types Device detail showingVLAN, interfaces, uptime, &more with drill-downDevice interfaces sortable by VLAN, connected devices, & utilization Interface traffic statistic - correlated 24 hr charts to detect intermittent eventsThe EtherScope nXG has out-of-the-box AutoTest profiles with best practice pass/fail thresholds for quick assessment of network configurations and services of Wi-Fi and wired networks.Ethernet Network: switch port PoE characteristics, link speed advertised vs negotiated, DHCP/DNS/Gateway availability and accessibility.Air Quality: assess number of APs, co-channel and adjacent channel interference, and channel utilizationWi-Fi Network: supports various authentication and security schemes to connect to SSIDs/BSSIDs for coverage by signal/noise, and DHCP/DNA/Gateway availability and accessibility.Wi-Fi Air Quality - detects oversubscribed channelsWi-Fi SSID connectivity &coverageSimplifies tasks and empowers technicians to verify complex networks with next generation AutoTestConfigurationTestingDocumentationCollaborationPath Analysis: shows the switch/router path connecting the EtherScope nXG to an IP device on across wired and Wi-Fi networks, and even beyond the local network, e.g., from the EtherScope nXG’s Wi-Fi port to a server in the cloud or data center on the Internet. The EtherScope nXG offers built-in tools to conduct further analysis of the devices along the path: view configuration, interface traffic statistics, launch Telnet or browser, conduct port scan, ping and more.Packet Capture: from both the Wi-Fi and Ethernet test interfaces. You can capture up to 10G line-rate to create a PCAP file of up to 1Gigabyte. Packet slicing and filtering are supported, and PAP files can be uploaded to theLink-Live Cloud Service for easy sharing.Cable Test: determine length, shorts, and split pairs and locate opens on UTP cable. Verify the wiremap of UTP and ScTP cable with a WireViewadapter. It can generate either analog tone or the unique digital tone for theFluke Networks IntelliTone™ Probe for quick cable tracing.Android Apps: Users can download apps from the Link-Live app store toaccomplish many tasks in addition to testing.Multiple advanced troubleshooting tools in oneMultiple profiles can be created for complex networks with multiple VLANs supported per switch port, and Wi-Fi networks with multiple SSIDs each with its own set of IP targets. These can then be organized into profilegroups that execute each test against each profile in sequence. The result is that multiple VLANs, and SSIDs can be verified and documented in one go. Since the pre-defined profiles can be executed individually, the profiles group serves as a resource for technicians to verify each specific VLAN orSSID during troubleshooting. With profile groups, engineers can transfertheir network configuration and test knowledge to technicians, saving training time and effort.Simplifies tasks and empowers technicians to verify complex networks withnext generation AutoTest (continued)Tools, such as a browser, are available to conduct device level investigationCable test with Wiremap detecting distance to fault Path Analysis shows the device & interfaces that UDP/TCP traffic traversesShows the interfaces of devices present in pathanalysisNBASE-T switch networkvalidationAdd & customize profiles for standardized testingExamples of Android apps available to download to EtherScope nXGThe EtherScope nXG has dedicated Wi-Fi and Ethernet management ports that empower a more experienced/knowledgeable remote engineer to control the EtherScope nXG to collaborate with technicians on-site. At locations with no Internet service, the Wi-Fi Management Port canconnect to a personal Wi-Fi hotspot for remote control, and upload results to the Link-Live Cloud Service.Apart from providing remote access, the dedicated management ports are used for discovery to access to SNMP MIBs of devices via a management VLAN isolated from client VLANs, and conduct Ping/TCP Connect tests and iPerf tests.Ordering GuideEXG-200Includes: (1) EXG-200 mainframe with Li-ION battery, G3-PWRADAPTER, SFP+MR-10G850, Inline RJ-AccessoriesSpecificationsNOTE: The battery will not charge if the internal temperature of the tester is above 122°F (50°C).Certifications and Complaince©2019 NetAlly.

EtherPeek NX的使用一、前言本文旨在推荐使用EtherPeek NX的同时，通过分析截取的QQ协议包，探讨QQ私有协议的一些特点。

二、EtherPeek NX概述前不久由于工作需要，修改madwifi代码分析无线接收包，但发送包无法获取，从源代码着手分析也过于复杂，所以才用上了Win下的截包软件EtherPeek NX，EtherPeek NX能根据OSI七层的架构，解析每个包且即时监视网路的各种状态，并能通过对问题的自动识别提供说明及解决方案，同时可以对多种网络状况提供Latency及Throughput解析，将网络上的所有结点沟通的状态以图形的方式完全显示出来，人机交互界面做的非常友好，当然，类似于其它截包软件，EtherPeek NX也需要WinPcap的支持，关于WinPcap 的更多信息可参考：/。

三、EtherPeek NX 2.0界面四、包分析五、QQ协议特点QQ协议有以下特点：1、默认采用UDP方式，客户端默认端口：4000，服务器端默认端口：8000；2、截取负载部分如下所示：02 19 0F 00 91 1A 37 03 DC CA EE 10 49 E4 F0 20 [42-57]C6 A1 5C 32 CB 1E 7F 42 76 D3 7B 6A A8 3E 41 AD [58-73]D4 34 2D 3E 64 56 3B E6 2E 3F 99 2D D4 60 DF 4F [74-89]BF F4 1B DB 40 43 9B ED 18 AD 6A 58 4D 10 C8 F0 [90-105]9D 5F 1E CC 83 3B A6 9E DC B3 00 03 [106-117]3、多次截包分析可知，前4个字节固定，表示内部协议版本：02 19 0F 00 ；4、第5个字节为命令类型编号：91；5、第6～第7的2个字节随机生成的包序列号（同一命令类型，连续多个包，依次递增）：1A 37（用于回应包的对号入座）；6、第8～第11的4个字节为QQ帐号，此处用的是明文方式，且自动补0：03 DC CA EE （转换成十进制为：64801518，作者的QQ号）；7、最后1字节为消息结束码：03；8、从客户端（本地）发往服务器端的所有包都包含上述的1～7，而服务器端回应客户端也应该包含相应的1～7；9、分析可知，QQ的消息包有包头，包体，包尾之分，而且包体有全加密，不加密和部分加密的区别；10、前面12个包大小一致，且顺序一致，后面的则错乱，或者推知前面完成口令认证过程。

Ethereal软件的安装与使用一、实验目的学会安装Ethereal软件，熟悉Ethereal，用ethereal来观察网络。

了解ethereal工具的使用方法。

了解使用ethereal抓包中各个字段的含义。

为进一步实验做准备。

二、实验内容Ethereal是一个开放源码的网络分析系统，也是目前最好的开放源码的网络协议分析器，支持Linux和Windows平台。

Ethereal起初由Gerald Combs开发，随后由一个松散的Etheral团队组织进行维护开发。

自从1998年发布最早的0.2版本至今，大量的志愿者为Ethereal添加新的协议解析器，如今Ethereal已经支持五百多种协议解析。

很难想象如此多的人开发的代码可以很好的融入系统中；并且在系统中加入一个新的协议解析器很简单，一个不了解系统的结构的新手也可以根据留出的接口进行自己的协议开发。

这都归功于Ehereal良好的设计结构。

事实上由于网络上各种协议种类繁多，各种新的协议层出不穷。

一个好的协议分析器必需有很好的可扩展性和结构，这样才能适应网络发展的需要不断加入新的协议解析器。

关于ethereal软件中option选项的说明：如下图所示。

●IP address:选择的网卡所对应的IP地址●Link-layer header type:数据链路层的协议，在以太网中一般是Ethernet II●Buffer size:数据缓存大小设定，默认是1M字节●Interface:选择采集数据包的网卡●Capture packets in promiscuous mode:设定在混杂模式下捕获数据，如果不选中，将只能捕获本机的数据通讯，默认情况下选中该项 Limit each packet to:设定只捕获数据包的前多少个字节（从以太网头开始计算），默认是68●Capture Filter:设定当前的数据包采集过滤器●File:设定数据包文件的保存位置和保存文件名，默认不保存●Use multiple files:启用多文件保存，默认不启用●Next file every:设定每个数据包文件的大小（单位是M，默认1M），只有启用Use multiple files后此项才可用●Next file every: 设定每个数据包文件的大小（单位是分钟，默认1分钟），只有启用Use multiple files后此项才可用●Ring buffer with:当保存多少个数据包文件后循环缓存，默认是2个文件，即保存2个数据包文件后丢弃缓存中的数据包，再添加新采集到的数据包●Stop capture after: 当保存多少个数据包文件后停止捕获，默认是1个文件Stop Capture 中●… after:捕获到多少个数据包后停止捕获，默认不启用，如启用，默认值是1●… after:捕获到多少M字节的数据包后停止捕获，默认不启用，如启用，默认值是1●… after:捕获多少分钟后停止捕获，默认不启用，如启用，默认值是1Display Options●Update list of packets in real time:实时更新捕获到的数据包列表信息●Automatic scrolling in live capture:对捕获到的数据包信息进行自动滚屏显示●Hide capture info dialog:隐藏捕获信息对话框Name Resolution●Enable MAC name resolution:把MAC地址前3位解析为相应的生产厂商●Enable network name resolution:启用网络地址解析，解析IP,IPX地址对应的主机名●Enable transport name resolution:启用端口名解析，解析端口号对应的端口名三、实验要求要求抓图（如下图），说明每一个字段的含义。
