Lightweight M2M is a protocol on top of CoAP that is used for device management. The specification contains a custom payload format - a simple type, length, value binary encoding. This patch adds support for dissecting this payload format. While not yet officially registered, the main open source implementation of the lwm2m protocol - eclipse's leshan - uses this content type 1542 for its messages.

= Wireshark wireshark-version:[] Release Notes
|
|
// AsciiDoc quick reference: http://powerman.name/doc/asciidoc
|
|
|
|
This is a semi-experimental release intended to test new features for Wireshark 2.2.
|
|
|
|
== 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
|
|
|

|
|
|
|
=== New and Updated Features
|
|
|
|
The following features are new (or have been significantly updated)
|
|
since version 2.0.0:
|
|
** You can now switch between between Capture and File Format dissection of
|
|
the current capture file via the View menu in the Qt GUI.
|
|
** You can now show selected packet bytes as ASCII, HTML, Image, ISO 8859-1, Raw or UTF-8.
|
|
** You can now use regular expressions in Find Packet.
|
|
|
|
//=== Removed Dissectors
|
|
|
|
=== New File Format Decoding Support
|
|
|
|
Wireshark is able to display the format of some types of files (rather than
|
|
displaying the contents of those files). This is useful when you're curious
|
|
about, or debugging, a file and its format. To open a capture file (such as
|
|
PCAP) in this mode specify "MIME Files Format" as the file's format in the
|
|
Open File dialog.
|
|
|
|
New files that Wireshark can open in this mode include:
|
|
|
|

=== Major API Changes
|
|
|
|
The libwireshark API has undergone some major changes:
|
|
|
|
* The address macros (e.g., SET_ADDRESS) have been removed. Use the
|
|
(lower case) functions of the same names instead.
|
|
|
|
* "old style" dissector functions (that don't return number of bytes
|
|
used) have been replaced in name with the "new style" dissector
|
|
functions.
|
|
|
|
* tvb_get_string and tvb_get_stringz have been replaced with
|
|
tvb_get_string_enc and tvb_get_stringz_enc respectively.
|
|
|
|
|
|
== Getting Wireshark
|
|
|
|
Wireshark source code and installation packages are available from
|
|
https://www.wireshark.org/download.html.
|
|
|
|
=== 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 https://www.wireshark.org/download.html#thirdparty[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.
|
|
|
|
