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 Gerald Combs receives ACM Software System Award eWeek • The Most Important Open-Source Apps of All Time PC Magazine • Editor's Choice McAfee SiteAdvisor Insecure.Org / Sectools.Org Original Author Gerald Combs <gerald[AT]wireshark.org> Contributors Gilbert Ramirez <gram[AT]alumni.rice.edu> Thomas Bottom <tom.bottom[AT]labxtechnologies.com> Chris Pane <chris.pane[AT]labxtechnologies.com> Hannes R.
