用Ethereal分析HTTP数据包
Ethereal 〔Ethereal：A Network Packet Sniffing Tool〕是当前较为流行的一种计算机网络调试和数据包嗅探软件。Ethereal 根本类似于tcpdump，但Ethereal 还具有设计完美的GUI和众多分类信息及过滤选项。用户通过 Ethereal，同时将网卡插入混合模式，可以查看到网络中发送的所有通信流量。 Ethereal 应用于故障修复、分析、软件和协议开发以及教育领域。它具有用户对协议分析器所期望的所有标准特征，并具有其它同类产品所不具备的有关特征。
Ethereal是一个图形用户接口〔GUI〕的网络嗅探器，能够完成与Tcpdump相同的功能，但操作界面要友好很多。Ehtereal和Tcpdump都依赖于pcap库〔libpcap〕，因此两者在许多方面非常相似〔如都使用相同的过滤规那么和关键字〕。Ethereal和其它图形化的网络嗅探器都使用相同的界面模式
