2019-12-18 18:29:53 +00:00
Wireshark is the world’ s most popular network protocol analyzer.
It is used for troubleshooting, analysis, development and education.
2013-03-15 01:33:46 +00:00
2018-02-04 23:15:02 +00:00

2013-03-15 01:33:46 +00:00
=== New and Updated Features
2020-11-08 06:36:47 +00:00
The following features are new (or have been significantly updated) since version 3.4.0:
2019-11-18 20:10:21 +00:00
2021-04-25 11:08:52 +00:00
* The Windows installers now ship with Npcap 1.31.
2021-04-12 20:51:18 +00:00
They previously shipped with Npcap 1.20.
2020-12-14 18:44:35 +00:00
2020-07-19 18:23:38 +00:00
* TCP conversations now support a completeness criteria, which facilitates the identification of TCP streams having any
of opening or closing handshakes, a payload, in any combination. It is accessed with the new tcp.completeness filter.
2020-11-08 06:36:47 +00:00
* Protobuf fields that are not serialized on the wire (missing in capture files) can now be displayed with default values
by setting the new 'add_default_value' preference. The default values might be explicitly declared in 'proto2' files,
or false for bools, first value for enums, zero for numeric types.
2018-12-13 00:39:20 +00:00
2021-05-30 08:58:14 +00:00
* Wireshark now supports reading Event Tracing for Windows (ETW). A new extcap named ETW reader is created that now can open an etl file,
convert all events in the file to DLT_ETW packets and write to a specified FIFO destination. Also, a new packet_etw dissector is
2020-12-04 23:00:02 +00:00
created to dissect DLT_ETW packets so Wireshark can display the DLT_ETW packet header, its message and packet_etw dissector
calls packet_mbim sub_dissector if its provider matches the MBIM provider GUID.
2021-02-22 11:48:46 +00:00
* "Follow DCCP stream" feature to filter for and extract the contents of DCCP streams.
2021-02-27 22:52:33 +00:00
* Wireshark now supports dissecting the rtp packet with OPUS payload.
2021-02-24 00:52:24 +00:00
* Importing captures from text files is now also possible based on regular expressions. By specifying a regex capturing a single
packet including capturing groups for relevant fields a textfile can be converted to a libcap capture file. Supported data
encodings are plain-hexadecimal, -octal, -binary and base64.
Also the timestamp format now allows the second-fractions to be placed anywhere in the timestamp and it will be stored with
nanosecond instead of microsecond precision.
2021-05-30 02:38:12 +00:00
* Display filter literal strings can now be specified using raw string syntax,
identical to raw strings in the Python programming language. This is useful
to avoid the complexity of using two levels of character escapes with regular
expressions.
2021-05-30 08:58:14 +00:00
* Significant RTP Player redesign and improvements (see Wireshark User Documentation,
https://www.wireshark.org/docs/wsug_html_chunked/ChTelPlayingCalls.html[Playing VoIP Calls] and
https://www.wireshark.org/docs/wsug_html_chunked/_rtp.html#ChTelRtpPlayer[RTP Player Window])
2021-04-18 19:04:57 +00:00
** RTP Player can play many streams in row
** UI is more responsive
** RTP Player maintains playlist, other tools can add/remove streams to it
** Every stream can be muted or routed to L/R channel for replay
** Save audio is moved from RTP Analysis to RTP Player. RTP Player saves what was played. RTP Player can save in multichannel .au or .wav.
** RTP Player added to menu Telephony>RTP>RTP Player
* VoIP dialogs (VoIP Calls, RTP Streams, RTP Analysis, RTP Player, SIP Flows) are non-modal, can stay opened on background
** Same tools are provided acros all dialogs (Prepare Filter, Analyse, RTP Player ...)
* Follow stream is now able to follow SIP call by SIP.Call-ID
2020-09-09 15:06:15 +00:00
* Follow stream YAML output format’ s has been changed to add timestamps and peers information (for more details see the user’ s guide,
{wireshark-users-guide-url}/ChAdvFollowStreamSection.html[Following Protocol Streams])
2021-05-30 08:58:14 +00:00
* IP fragments between public IPv4 addresses are now reassembled even if they have different VLAN IDs. Reassembly of IP fragments
where one endpoint is a private (RFC 1918 section 3) or link-local (RFC 3927) IPv4 address continues to take the VLAN ID into
account, as those addresses can be reused. To revert to the previous behavior and not reassemble fragments with different VLAN IDs,
turn on the "Enable stricter conversation tracking heuristics" top level protocol preference.
2021-01-20 04:46:51 +00:00
2021-06-04 18:42:26 +00:00
* tshark can now export TLS session keys with the --export-tls-session-keys option.

=== New Protocol Support
2016-06-03 16:21:21 +00:00
2020-10-22 19:13:21 +00:00
// Add one protocol per line between the -- delimiters in the format
// "Full protocol name (Abbreviation)"
Switch from AsciiDoc to Asciidoctor.
Switch the markup text processor for files in the docbook directory from
AsciiDoc to Asciidoctor. Asciidoctor has several useful features (such
as direct PDF output) and is actively developed. It's written in Ruby
but that dependency can be sidestepped with AsciidoctorJ, a
self-contained bundle that only depends on the JRE.
The current toolchain targets require Python, AsciiDoc, DocBook XML,
DocBook XSL, Java, FOP, xsltproc, lynx, and the HTMLHelp compiler:
HTML: AsciiDoc → DocBook XML → xsltproc + DocBook XSL
Chunked HTML: AsciiDoc → DocBook XML → xsltproc + DocBook XSL
PDF: AsciiDoc → DocBook XML → xsltproc + DocBook XSL → FOP
HTMLHelp: AsciiDoc → DocBook XML → xsltproc + DocBook XSL → HHC
This change removes the AsciiDoc and FOP requirements and adds either
AsciidoctorJ or Asciidoctor + Ruby:
HTML: Asciidoctor → DocBook XML → xsltproc + DocBook XSL
Chunked HTML: Asciidoctor → DocBook XML → xsltproc + DocBook XSL
PDF: Asciidoctor
HTMLHelp: Asciidoctor → DocBook XML → xsltproc + DocBook XSL → HHC
Ideally we could generate all of these using AsciidoctorJ, Java, and
lynx. Unfortunately we're not there yet.
The release notes depend on several macros (ws-buglink, ws-salink,
cve-idlink, sort-and-group). Add Asciidoctor (Ruby) equivalents.
Remove the BUILD_xxx_GUIDES CMake options and add various output targets
automatically. This means that you have to build the various documentation
targets explicitly.

== Getting Wireshark
Wireshark source code and installation packages are available from
2014-09-17 00:15:56 +00:00
https://www.wireshark.org/download.html.
2013-03-15 01:33:46 +00:00
=== Vendor-supplied Packages
2020-09-15 20:56:25 +00:00
Most Linux and Unix vendors supply their own Wireshark packages.
You can usually install or upgrade Wireshark using the package management system specific to that platform.
A list of third-party packages can be found on the
https://www.wireshark.org/download.html#thirdparty[download page]
2013-03-15 01:33:46 +00:00
on the Wireshark web site.
== File Locations
2020-09-15 20:56:25 +00:00
Wireshark and TShark look in several different locations for preference files, plugins, SNMP MIBS, and RADIUS dictionaries.
These locations vary from platform to platform.
You can use About → Folders to find the default locations on your system.
