Wireshark 3.6.1

Wireshark

Wireshark is a network packet analyzer. A network packet analyzer will try to capture network packets and tries to display that packet data as detailed as possible. You could think of a network packet analyzer as a measuring device used to examine what's going on inside a network cable, just like a voltmeter is used by an electrician to examine what's going on inside an electric cable (but at a higher level, of course). In the past, such tools were either very expensive, proprietary, or both. However, with the advent of Wireshark, all that has changed. Wireshark is perhaps one of the best open source packet analyzers available today.

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, OS X, 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
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 platfrom)
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

New and Updated Features

The 'console.log.level' preference was removed in Wireshark 3.6.0. This release adds an '-o console.log.level:' backward-compatibilty option on the CLI that maps to the new logging sub-system. Note that this does not have bitmask semantics and does not correspond to any actual preference. It is just a transition mechanism for users that were relying on this CLI option and will be removed in the future. To see the new diagnostic output options consult the manpages or the output of '--help'.

Updated Protocol Support

ANSI A I/F, AT, BitTorrent DHT, FF, GRPC, IEC 101/104, IEEE 802.11, IEEE 802.11 Radiotap, IPsec, Kafka, QUIC, RTMPT, RTSP, SRVLOC, Sysdig Event, and TECMP

New and Updated Capture File Support
