Wireshark 是全球用户量多的网络协议分析/网络封包分析软件。它使您可以从微观角度查看网络中发生的事情，并且已逐渐成为行业标准（通常是法律上）。
丰富的功能：
深入检查数百种网络协议
实时捕获和离线分析
标准三窗格数据包浏览器
多平台：在Windows，Linux，macOS，Solaris，FreeBSD，NetBSD和许多其他操作系统上运行
捕获的网络数据可以通过 GUI 或 TTY 模式的 TShark 实用程序进行浏览
业界最强大的显示过滤器
丰富的 VoIP 分析
读取/写入许多不同的捕获文件格式：tcpdump（libpcap），Pcap NG，Catapult DCT2000，Cisco Secure IDS iplog，Microsoft Network Monitor，Network GeneralSniffer®（压缩和未压缩），Sniffer®Pro和NetXray®，Network Instruments Observer ，NetScreen监听，Novell LANalyzer，RADCOM WAN / LAN分析仪，Shomiti / Finisar Surveyor，Tektronix K12xx，Visual Networks Visual UpTime，WildPackets EtherPeek / TokenPeek / AiroPeek等
使用gzip压缩的捕获文件可以即时解压缩
可以从以太网，IEEE 802.11，PPP / HDLC，ATM，蓝牙，USB，FDDI等读取实时数据（取决于您的平台）
对许多协议的解密支持，包括IPsec，ISAKMP，Kerberos，SNMPv3，SSL / TLS，WEP 和 WPA/WPA2
可以将着色规则应用于数据包列表，以进行快速，直观的分析
输出可以导出为XML，PostScript®，CSV或纯文本
Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions. Wireshark development thrives thanks to the volunteer contributions of networking experts around the globe and is the continuation of a project started by Gerald Combs in 1998.
Wireshark has a rich feature set which includes the following:
Deep inspection of hundreds of protocols, with more being added all the time
Live capture and offline analysis
Standard three-pane packet browser
Multi-platform: Runs on Windows, Linux, macOS, Solaris, FreeBSD, NetBSD, and many others
Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
The most powerful display filters in the industry
Rich VoIP analysis
Read/write many different capture file formats: tcpdump (libpcap), Pcap NG, Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®, Network Instruments Observer, NetScreen snoop, Novell LANalyzer, RADCOM WAN/LAN Analyzer, Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek/TokenPeek/AiroPeek, and many others
Capture files compressed with gzip can be decompressed on the fly
Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platform)
Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
Coloring rules can be applied to the packet list for quick, intuitive analysis
Output can be exported to XML, PostScript®, CSV, or plain text
