Wireshark is a free and open source packet analyzer.
It is used for network troubleshooting, analysis, software and communications protocol development.
It formely known as Ethereal, Wireshark allows the user to put the network interface controllers for using Sniffing and can see all the live traffic on the Wireshark Interface.
New Bug Fixes
- Upgrading to latest version uninstalls Microsoft Visual C++ redistributable. (Bug 12712)
- Extcap errors not reported back to UI. (Bug 11892)
The following features are new (or have been significantly updated) since version 2.2.0rc2:
No major changes since 2.2.0rc2.
The following features are new (or have been significantly updated) since version 2.2.0rc1:
"Decode As" supports SSL (TLS) over TCP.
The following features are new (or have been significantly updated) since version 2.1.1:
Invalid coloring rules are now disabled instead of discarded. This will provide backward compatibility with a coloring rule change in Wireshark 2.2.
The following features are new (or have been significantly updated) since version 2.1.0:
- Added -d option for Decode As support in Wireshark (mimics TShark functionality)
- The Qt UI, GTK+ UI, and TShark can now export packets as JSON. TShark can additionally export packets as Elasticsearch-compatible JSON.
- The Qt UI now supports the -j, -J, and -l flags. The -m flag is now deprecated.
- The Conversations and Endpoints dialogs are more responsive when viewing large numbers of items.
- The RTP player now allows up to 30 minutes of silence frames.
- Packet bytes can now be displayed as EBCDIC.
- The Qt UI loads captures faster on Windows.
- proto_tree_add_checksum was added as an API. This attempts to standardize how checksums are reported and filtered for within *Shark. There are no more individual "good" and "bad" filter fields, protocols now have a "checksum.status" field that records "Good", "Bad" and "Unverified" (neither good or bad). Color filters provided with Wireshark have been adjusted to the new display filter names, but custom ones may need to be updated.
The following features are new (or have been significantly updated) since version 2.0.0:
- The intelligent scroll bar now sits to the left of a normal scroll bar and provides a clickable map of nearby packets.
- 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, UTF-8, a C array, or YAML.
You can now use regular expressions in Find Packet and in the advanced preferences.
Name resolution for packet capture now supports asynchronous DNS lookups only. Therefore the "concurrent DNS resolution" preference has been deprecated and is a no-op. To enable DNS name resolution some build dependencies must be present (currently c-ares). If that is not the case DNS name resolution will be disabled (but other name resolution mechanisms, such as host files, are still available).The byte under the mouse in the Packet Bytes pane is now highlighted.
- TShark supports exporting PDUs via the -U flag.
- The Windows and OS X installers now come with the "sshdump" and "ciscodump" extcap interfaces.
- Most dialogs in the Qt UI now save their size and positions.
- The Follow Stream dialog now supports UTF-16.
- The Firewall ACL Rules dialog has returned.
- The Flow (Sequence) Analysis dialog has been improved.
- We no longer provide packages for 32-bit versions of OS X.
- The Bluetooth Device details dialog has been added.
