Wireshark 3.4.0

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

The following features are new (or have been significantly updated) since version 3.3.1:

  • The Protobuf fields defined as google.protobuf. Timestamp type of Protobuf standard library can now be dissected as Wireshark fields of absolute time type.

The following features are new (or have been significantly updated) since version 3.3.0:

  • The Windows installers now ship with Npcap 1.00. They previously shipped with Npcap 0.9997.
  • The Windows installers now ship with Qt 5.15.1. They previously shipped with Qt 5.12.8.

The following features are new (or have been significantly updated) since version 3.2.0:

  • Windows executables and installers are now signed using SHA-2 only.
  • Save RTP stream to .au supports any codec with 8000 Hz rate supported by Wireshark (shown in RTP player). If save of audio is not possible (unsupported codec or rate), silence of same length is saved and warning is shown.
  • Asynchronous DNS resolution is always enabled. As a result, the c-ares library is now a required dependency.
  • Protobuf fields can be dissected as Wireshark (header) fields that allows user input the full names of Protobuf fields or messages in Filter toolbar for searching.
  • Dissectors based on Protobuf can register themselves to a new 'protobuf_field' dissector table, which is keyed with the full names of fields, for further parsing fields of BYTES or STRING type.
  • Wireshark is able to decode, play, and save iLBC payload on platforms where the iLBC library is available.
  • Wireshark is able to decode, play, and save opus payload on platforms where the opus library is available.
  • “Decode As” entries can now be copied from other profiles using a button in the dialog.
  • sshdump can now be copied to multiple instances. Each instance will show up a different interface and will have its own profile.
  • The main window now supports a packet diagram view, which shows each packet as a textbook-style diagram.
  • Filter buttons (“Preferences → Filter Buttons”) can be grouped by using “//” as a path separator in the filter button label.
  • IPP Over USB packets can now be dissected and displayed
