抓包工具Ethereal的简单使用

当LoadRunner不支持低版本IE浏览器录制脚本时,Ethereal抓包工具提供了解决方案。通过下载安装Ethereal,选择网卡开始抓包,然后根据IP地址筛选相关数据,通过Flow TCP Stream获取所需信息,用于构建自定义请求。此方法适用于处理需要手动开发脚本的项目。

都知道Loadrunner可以录制脚本,简单实用

但是在实际项目中,用到的浏览器普遍都是IE,而且版本很低

Loadrunner只支持9版本以上的IE浏览器

那么脚本开发就成了难题

这时,抓包工具Ethereal就巧妙的解决了这个问题:

下载安装成功后:

  • 打开页面是这样的

  • 接着点击工具栏的Capture下的Interface···

  • 接着点击Capture,选择网卡,涂鸦的是网卡信息

  • 那么就开始抓包开始了,得到下面的页面

  • 这时就开始打开url开始需要操作的动作,Ethereal就开始抓包了,结束后点击抓包工具最下面的
Ethereal is a GUI network protocol analyzer. It lets you interactively browse packet data from a live network or from a previously saved capture file. See: http://www.ethereal.com for new versions, documentation, ... Ethereal's native capture file format is libpcap format, which is also the format used by tcpdump and various other tools. So Ethereal can read capture files from: -libpcap/WinPcap, tcpdump and various other tools using tcpdump's capture format -snoop and atmsnoop -Shomiti/Finisar Surveyor captures -Novell LANalyzer captures -Microsoft Network Monitor captures -AIX's iptrace captures -Cinco Networks NetXRay captures -Network Associates Windows-based Sniffer captures -Network General/Network Associates DOS-based Sniffer (compressed or uncompressed) captures -AG Group/WildPackets EtherPeek/TokenPeek/AiroPeek/EtherHelp/PacketGrabber captures -RADCOM's WAN/LAN analyzer captures -Network Instruments Observer version 9 captures -Lucent/Ascend router debug output -files from HP-UX's nettl -Toshiba's ISDN routers dump output -the output from i4btrace from the ISDN4BSD project -traces from the EyeSDN USB S0. -the output in IPLog format from the Cisco Secure Intrusion Detection System -pppd logs (pppdump format) -the output from VMS's TCPIPtrace/TCPtrace/UCX$TRACE utilities -the text output from the DBS Etherwatch VMS utility -Visual Networks' Visual UpTime traffic capture -the output from CoSine L2 debug -the output from Accellent's 5Views LAN agents -Endace Measurement Systems' ERF format captures -Linux Bluez Bluetooth stack hcidump -w traces There is no need to tell Ethereal what type of file you are reading; it will determine the file type by itself. Ethereal is also capable of reading any of these file formats if they are compressed using gzip. Ethereal recognizes this directly from the file; the '.gz' extension is not required for this purpose.
