Versie 4.6.0 van de opensource protocolanalyser en packetsniffer Wireshark is uitgekomen. Met dit programma kunnen verschillende datapakketten en netwerkprotocollen op het netwerk worden geanalyseerd. Ook kan het programma eerder opgeslagen dataverkeer als invoer gebruiken. Wireshark is te downloaden voor 64bit-uitvoeringen van Windows en macOS. De broncode is beschikbaar voor gebruik op Linux, Solaris en *BSD. In deze uitgave zijn de volgende veranderingen en verbeteringen aangebracht:
New and Updated FeaturesRemoved Features and Support
- Wireshark can dissect process information, packet metadata, flow IDs, drop information, and other information provided by
tcpdumpon macOS.- The Windows installers now ship with Npcap 1.83. They previously shipped with Npcap 1.79.
- The Windows and macOS installers now ship with Qt 6.9.3. They previously shipped with Qt 6.5.3.
- We now ship universal macOS installers instead of separate packages for Arm64 and Intel. Issue 17294
- WinPcap is no longer supported. On Windows, use Npcap instead, uninstalling WinPcap if necessary. The final release of WinPcap was version 4.1.3 in 2013. It only supports up to Windows 8, which is no longer supported by Microsoft or Wireshark.
- A new “Plots” dialog has been added, which provides scatter plots in contrast to the “I/O Graphs” dialog, which provides histograms. The Plots dialog window supports multiple plots, markers, and automatic scrolling.
- Live captures can be compressed while writing. (Previously there was support for compressing when performing multiple file capture, at file rotation time.) The
--compressoption in TShark works on live captures as well. Issue 9311- Absolute time fields, regardless of field display in the Packet Details, are always written in ISO 8601 format in UTC with -T json. This was already the case for -T ek since version 4.2.0. JSON is primarily a data interchange format read by software, so a standard format is desirable.
- When absolute times field are output with -T fields, the "show" field of -T pdml, or in custom columns (including CSV output of columns), the formatting similar to asctime (e.g., Dec 18, 2017 05:28:39.071704055 EST) has been deprecated in favor of ISO 8601. For backwards compatibility, a preference has been added, protocols.display_abs_time_ascii, which can be set to continue to format times as before. This preference can also be set to never use ASCII time and to use ISO 8601 time formatting in the protocol tree (Packet Details) as well. It is possible that a future release will remove the ascitime style formatting entirely.
- UTC frame time column formats (including "Time (format as specified)" when a UTC time display format is selected) have a "Z" suffix per ISO 8601. Local time formats remain unqualified (including if the local time zone is UTC.) Custom columns displaying FT_ABSOLUTE_TIME already had time zone indication.
- The TShark
-Goption for generating glossary reports does not need to be the first option given on the command line anymore. In addition, the reports now are affected by other command line options such as-o,-d, and--disable-protocol, in addition to the-Coption, which was already supported. (Thedefaultprefsreport remains unaffected by any other options.) As a part of this change,-Gwith no argument, which was previously deprecated, is no longer supported. Usetshark -G fieldsto produce the same report. Also, the syntax for only listing fields with a certain prefix has changed totshark -G fields,prefix.- The underlying type of EUI-64 fields has been switched to bytes when packet matching, similar to most other address formats. This means that EUI-64 addresses can be sliced and compared to other bytes types, e.g. the filter
wpan.src64[:3] == eth.src[:3]. Fields can still be specified using 64-bit unsigned integer literals, though arithmetic with other integers is no longer supported.- Wireshark can now decrypt NTP packets using NTS (Network Time Security). To decrypt packets, the NTS-KE (Network Time Security Key Establishment Protocol) packets need to be present, alongside the TLS client and exporter secrets. Additionally, the parts of a NTP packet which can be cryptographically authenticated (from NTP packet header until the end of the last extension field that precedes the NTS Authenticator and Encrypted Extension Fields extension field) are checked for validity.
- Wireshark’s ability to decrypt MACsec packets has been expanded to either use the SAK unwrapped by the MKA dissector, or the PSK configured in the MACsec dissector. To enable the MKA dissector to unwrap the SAK, the CAK for the applicable CKN can be entered in the extended CKN/CAK Info UAT in the MKA dissector preferences. The ability of the MACsec dissector to decrypt packets using a PSK has been extended to a list of PSKs, which can entered through a new UAT.
- The TCP Stream Graph axes now use units with SI prefixes. Issue 20197
- Custom columns have an option to show the values using the same format as in Packet Details.
- Custom column complex expressions (e.g., with arithmetic, filter functions, etc.) that return numeric results are sorted numerically instead of lexicographically.
- Display filter functions
floatanddoubleare added to allow explicitly converting field types like integers and times to single and double precision floats. They can be used to perform further arithmetic operations on fields of different types, including in custom column definitions.- The minimum width of the I/O Graph dialog window has been reduced, so it should work better on small resolution desktops, especially in certain languages. To enable this, some checkbox controls were moved to the graph right-click context menu. Issue 20147
- X.509 certificates, used in TLS and elsewhere, can be exported via the File › Export Objects menu in Wireshark (under the name "X509AF") and
--export-objectsin TShark (with the protocol namex509af.)- Zstandard Content-Encoding is supported in the HTTP and HTTP/2 dissectors.
- Follow Stream is supported for MPEG 2 Transport Stream PIDs, and for Packetized Elementary Streams contained within MPEG 2 TS. The latter can be used to extract audio or video for playback with other tools.
- DNP 3 (Distributed Network Protocol 3) is now supported in the Conversations and Endpoints table dialogs.
- The Lua supplied preloaded libraries
bitandrex_pcre2are loaded in a way that adds them to thepackage.loadedtable, as though throughrequire, so thatrequire("bit")andrequire("rex_pcre2")statements in Lua dissectors, while usually superfluous, behave as expected. Issue 20213- The packet list (Wireshark) and event list (Stratoshark) no longer support rows with multiple lines. Issue 14424
- The ethers file can also contain EUI-64 to name mappings. Issue 15487
- Wireshark’s "Import from Hex Dump" feature and text2pcap now support byte groups with 2 to 4 bytes (with an option for little-endian byte order), and support hexadecimal offsets with a
0xor0Xprefix (as produced bytcpdump -x, among others). Issue 16193- Frame timestamps can be added as preamble to hex dumps in Wireshark from the "Print" and "Export Packet Dissection" dialogs, and in TShark with the
--hexdump timeoption. Issue 17132- Lua now has a
Conversationobject, which exposes conversations and conversation data to Lua. Issue 15396- An Edit › Copy › as HTML menu item has been added, along with associated context menu items and a keyboard shortcut. It provides an option (via knobs in preferences) to copy plain text with aligned columns along with an ability to select a copy format to be used when copied via keyboard shortcut.
- The "no duplicate keys" version of JSON output that tshark has supported since 2.6.0 is available through the GUI Export Dissections Dialog. Note that this format does not necessarily preserve the ordering of all children in a tree, if sibling with identical keys are not consecutive.
- The GUI Export Dissections Dialog can output raw hex bytes of the frame data for each field with or without exporting the field values, the same formats as the "-T json -x" and "-T jsonraw" output modes, respectively, of TShark.
- The Conversations and Endpoints dialogs have an option to display byte counts and bit rates in exact counts instead of human-readable numbers with SI units. The default setting when opening a dialog is controlled by a Statistics preference, "conv.machine_readable". The same preference controls whether precise byte counts are used in the TShark "-z conv" and "-z endpoints" taps.
- The output format for some TShark statistics taps (those selected with "-z <tap>,tree", which use the stats_tree system) can be controlled via a preference "-o statistics.output_format".
- The color scheme can be set to Light or Dark mode independently of the current OS default on Windows and macOS, if Wireshark is built with Qt 6.8 or later as the official installers are. Issue 19328
- libxml2 is now a required dependency. Note that Wireshark will not build with libxml2 2.15.0, but other versions should work.
- The View menu has an option to Redissect Packets manually, which can be useful when address resolution or decryption secrets have changed.
- HTTP2 tracking of 3GPP session over 5G Service Based Interfaces is now optional available. When enabled "Associate IMSI" will be add on HTTP2 streams which has been found belong to a session.
- Building the documentation on Windows no longer requires Java.
- On Linux, capture filters that use BPF extensions like "inbound", "outbound", and "ifindex" can be used for capturing (and compiled by the Compiled Filter dialog). Instead of always being rejected by the syntax checker, they will be marked as unknown.
