Wireshark helps network administrators to solve protocol issues by diagnosing the problems in the software protocols.
Wireshark is a famous network analysis or packet sniffer tool protocols.
Wireshark examine data from a live network, and can also take a snapshot of the various communications that work on it at another time. Wireshark proposes to see the "dissector tables" directly from the main window. The application can export objects to SMB screen or display the compiled BPF code for capture filters. Finally, Wireshark supports a variety of protocols such as ADwin, Apache Etch, JSON, reload or Wi-Fi P2P (Wi-Fi Direct).
The interface is quite austere, hides an extremely powerful that only experts can use software correctly.
This software is essential for any network administrator to diagnose problems in the software protocols.

Getting Wireshark
Wireshark source code and installation packages are available from
the download page on the main web site.
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 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
Wireshark may appear offscreen on multi-monitor Windows systems.
(Bug 553)
Wireshark might make your system disassociate from a wireless
network on OS X. (Bug 1315)
Dumpcap might not quit if Wireshark or TShark crashes. (Bug 1419)
The BER dissector might infinitely loop. (Bug 1516)
Wireshark can't dynamically update the packet list. This means
that host name resolutions above a certain response time threshold
won't show up in the packet list. (Bug 1605)
Capture filters aren't applied when capturing from named pipes.
(Bug 1814)
Wireshark might freeze when reading from a pipe. (Bug 2082)
Capturing from named pipes might be delayed on Windows. (Bug 2200)
Filtering tshark captures with display filters (-R) no longer
works. (Bug 2234)
