Per Gerald Combs, Wireshark project Founder …“Wireshark is a tool and a community. SharkFest’s aim is to support ongoing Wireshark development, to educate and inspire current and future generations of computer science and IT professionals responsible for managing, troubleshooting, diagnosing and securing legacy and modern networks, and to encourage widespread use of the free analysis tool. Learn more about SharkFest in our FAQ PDF. Wireshark core code contributors also gather during the conference days to enrich and evolve the tool to maintain its relevance in ensuring the productivity of modern networks. SharkFest attendees hone their skills in the art of packet analysis by attending lecture and lab-based sessions delivered by the most seasoned experts in the industry. SharkFest™, launched in 2008, is a series of annual educational conferences staged in various parts of the globe and focused on sharing knowledge, experience and best practices among the Wireshark® developer and user communities.

Output can be exported to XML, PostScript®, CSV, or plain text.

Coloring rules can be applied to the packet list for quick, intuitive analysis.

Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2.

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).

Capture files compressed with gzip can be decompressed on the fly.

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.

The most powerful display filters in the industry.

Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility.

Multi-platform: Runs on Windows, Linux, macOS, Solaris, FreeBSD, NetBSD, and many others.

Deep inspection of hundreds of protocols, with more being added all the time.

Wireshark has a rich feature set which includes the following:

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.

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 is the world’s foremost and widely-used network protocol analyzer.
