Wireshark is the world's foremost network protocol analyzer, and is the de facto standard across many industries and educational institutions.
- Deep inspection of hundreds of protocols, with more being added all the time
- Live capture and offline analysis
- Standard three-pane packet browser
- Multi-platform: Runs on Windows, Linux, OS X, Solaris, FreeBSD, NetBSD, and many others
- Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
- The most powerful display filters in the industry
- Rich VoIP analysis
- Read/write many different capture file formats
- Capture files compressed with gzip can be decompressed on the fly
- Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platfrom)
- Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
- Coloring rules can be applied to the packet list for quick, intuitive analysis
- Output can be exported to XML, PostScript®, CSV, or plain text
# Bug Fixes
- Redirecting the standard output didn’t redirect the output the of -D or -L flags. This fix means that the output of those flags now goes to the standard output, not the standard error, as it did in previous releases.
# New and Updated Features
- Wireshark on 32- and 64-bit Windows supports automatic updates.
- The packet bytes view is faster.
- You can now display a list of resolved host names in "hosts" format within Wireshark.
- The wireless toolbar has been updated.
- Wireshark on Linux does a better job of detecting interface addition and removal.
- It is now possible to compare two fields in a display filter (for example: udp.srcport != udp.dstport). The two fields must be of the same type for this to work.
- The Windows installers ship with WinPcap 4.1.3, which supports Windows 8.
- USB type and product name support has been improved.
- All Bluetooth profiles and protocols are now supported.
- Wireshark now calculates HTTP response times and presents the result in a new field in the HTTP response. Links from the request’s frame to the response’s frame and vice-versa are also added.
- The main welcome screen and status bar now display file sizes using strict SI prefixes instead of old-style binary prefixes.
- Capinfos now prints human-readable statistics with SI suffixes by default.
- It is now possible to open a referenced packet (such as the matched request or response packet) in a new window.
- Tshark can now display only the hex/ascii packet data without requiring that the packet summary and/or packet details are also displayed. If you want the old behavior, use -Px instead of just -x.
- Wireshark can be compiled using GTK+ 3.
- The Wireshark application icon, capture toolbar icons, and other icons have been updated.
- Tshark’s filtering and multi-pass analysis have been reworked for consistency and in order to support dependent frame calculations during reassembly. See the man page descriptions for -2, -R, and -Y.
- Tshark’s -G fields2 and -G fields3 options have been eliminated. The -G fields option now includes the 2 extra fields that -G fields3 previously provided, and the blurb information has been relegated to the last column since in many cases it is blank anyway.
- Wireshark dropped the left-handed settings from the preferences. This is still configurable via the GTK settings (add "gtk-scrolled-window-placement = top-right" in the config file, which might be called /.gtkrc-2.0 or /.config/gtk-3.0/settings.ini).
- Wireshark now ships with two global configuration files: Bluetooth, which contains coloring rules for Bluetooth and Classic, which contains the old-style coloring rules.
- The LOAD() metric in the IO-graph now shows the load in IO units instead of thousands of IO units.
