Wireshark 1.12.0 RC2
Wireshark (precedentemente chiamato Ethereal) è un software per analisi di protocollo, o packet sniffer (letteralmente annusa-pacchetti) utilizzato per la soluzione di problemi di rete, per l´analisi e lo sviluppo di protocolli o di software di comunicazione, per la didattica. Wireshark possiede tutte le caratteristiche di un analizzatore di protocollo standard.

Note di rilascio:

I´m proud to announce the release of Wireshark 1.12.0-rc2. This is the
first public release candidate for Wireshark 1.12.0 (rc1 was only
available as development builds).

What is Wireshark?

Wireshark is the world´s most popular network protocol
analyzer. It is used for troubleshooting, analysis, development
and education.

What´s New

Bug Fixes

The following bugs have been fixed:
* "On-the-wire" packet lengths are limited to 65535 bytes.
([1]Bug 8808, ws-buglink:9390)
* "Follow TCP Stream" shows only the first HTTP req+res.
([2]Bug 9044)
* Files with pcap-ng Simple Packet Blocks can´t be read.
([3]Bug 9200)
* MPLS-over-PPP isn´t recognized. ([4]Bug 9492)

New and Updated Features

The following features are new (or have been significantly
updated) since version 1.11.3:
* Transport name resolution is now disabled by default.
* Support has been added for all versions of the DCBx
* Cleanup of LLDP code, all dissected fields are now

The following features are new (or have been significantly
updated) since version 1.11.2:
* Qt port:
+ The About dialog has been added
+ The Capture Interfaces dialog has been added.
+ The Decode As dialog has been added. It managed to
swallow up the User Specified Decodes dialog as well.
+ The Export PDU dialog has been added.
+ Several SCTP dialogs have been added.
+ The statistics tree (the backend for many Statistics
and Telephony menu items) dialog has been added.
+ The I/O Graph dialog has been added.
+ French translation has updated.

The following features are new (or have been significantly
updated) since version 1.11.1:
* Mac OS X packaging has been improved.

The following features are new (or have been significantly
updated) since version 1.11.0:
* Dissector output may be encoded as UTF-8. This includes
TShark output.
* Qt port:
+ The Follow Stream dialog now supports packet and TCP
stream selection.
+ A Flow Graph (sequence diagram) dialog has been added.
+ The main window now respects geometry preferences.

The following features are new (or have been significantly
updated) since version 1.10:
* Wireshark now uses the Qt application framework. The new UI
should provide a significantly better user experience,
particularly on Mac OS X and Windows.
* The Windows installer now uninstalls the previous version
of Wireshark silently. You can still run the uninstaller
manually beforehand if you wish to run it interactively.
* Expert information is now filterable when the new API is in
* The "Number" column shows related packets and protocol
conversation spans (Qt only).
* When manipulating packets with editcap using the -C
<choplen> and/or -s <snaplen> options, it is now possible
to also adjust the original frame length using the -L
* You can now pass the -C <choplen> option to editcap
multiple times, which allows you to chop bytes from the
beginning of a packet as well as at the end of a packet in
a single step.
* You can now specify an optional offset to the -C option for
editcap, which allows you to start chopping from that
offset instead of from the absolute packet beginning or
* "malformed" display filter has been renamed to
"_ws.malformed". A handful of other filters have been given
the "_ws." prefix to note they are Wireshark application
specific filters and not dissector filters.
* The Kerberos dissector has been replaced with an auto
generated one from ASN1 protocol description, changing a
lot of filter names.

Removed Dissectors

* The ASN1 plugin has been removed as it´s deemed obsolete.
* The GNM dissector has been removed as it was never used.
* The Kerberos hand made dissector has been replaced by one
generated from ASN1 code.

Platform Support

Support for Windows XP has been deprecated. We will make an
effort to support it for as long as possible but our ability to
do so depends on upstream packages and other factors beyond our

U3 packages are no longer supported or provided.

This is the last major release that will support 32-bit
versions of Mac OS X.

Major API Changes

The libwireshark API has undergone some major changes:
* A more flexible, modular memory manager (wmem) has been
added. It was available experimentally in 1.10 but is now
mature and has mostly replaced the old emem API (which is
* A new API for expert information has been added, replacing
the old one.
* The tvbuff API has been cleaned up: tvb_length has been
renamed to tvb_captured_length for clarity, and
tvb_get_string and tvb_get_stringz have been deprecated in
favour of tvb_get_string_enc and tvb_get_stringz_enc.
* dissector_try_heuristic() signature has been changed to
return heur_dtbl_entry_t to make it possible to save it and
use it in subsequent calls to avoid the overhead of going
trough the heuristics list.

Getting Wireshark

Wireshark source code and installation packages are available
from [5]

Vendor-supplied Packages

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 [6]download page on
the Wireshark web site.

File Locations

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.

Known Problems

Dumpcap might not quit if Wireshark or TShark crashes. ([7]Bug

The BER dissector might infinitely loop. ([8]Bug 1516)

Capture filters aren´t applied when capturing from named pipes.

Filtering tshark captures with read filters (-R) no longer
works. ([9]Bug 2234)

The 64-bit Windows installer does not support Kerberos
decryption. ([10]Win64 development page)

Resolving ([11]Bug 9044) reopens ([12]Bug 3528) so that
Wireshark no longer automatically decodes gzip data when
following a TCP stream.

Application crash when changing real-time option. ([13]Bug

Hex pane display issue after startup. ([14]Bug 4056)

Packet list rows are oversized. ([15]Bug 4357)

Summary pane selected frame highlighting not maintained.
([16]Bug 4445)

Wireshark and TShark will display incorrect delta times in some
cases. ([17]Bug 4985)

The 64-bit Mac OS X installer doesn´t support Mac OS X 10.9
([18]Bug 9242)
