=== Extcap modules ===
The following tools support capturing on devices not directly supported by libpcap/WinPcap/Npcap, using the [[https://www.wireshark.org/docs/man-pages/extcap.html extcap]] mechanism.
* [[https://github.com/cardigliano/wireshark-fritzbox wireshark-fritzbox]] - allows you to run a remote capture on a FRITZ!Box Internet gateway
This is a place for scripts and tools related to Wireshark / TShark that users may like to share, and for links to related NetworkTroubleshooting tools.
You will find additional development related tools in the Development page.
Some command line tools are shipped together with Wireshark. These tools are useful to work with capture files.
capinfos is a program that reads a saved capture file and returns any or all of several statistics about that file
dumpcap a small program whose only purpose is to capture network traffic, while retaining advanced features like capturing to multiple files (since version 0.99.0). Dumpcap is the engine under the Wireshark/tshark hood. For long-term capturing, this is the tool you want.
editcap edit and/or translate the format of capture files
mergecap merges multiple capture files into one
randpkt random packet generator
rawshark dump and analyze raw libpcap data
reordercap reorder input file by timestamp into output file
text2pcap generates a capture file from an ASCII hexdump of packets
tshark is the command-line equivalent of Wireshark, similar in many respects to tcpdump/WinDump but with many more features. Learn it, use it, love it.
dumpcap.bat A batch file front-end for dumpcap.exe. It allows you to save dumpcap.exe settings, be notified of capture events or trigger dumpcap.exe capturing after a capture event occurs. It also provides hooks for performing custom actions through user-defined batch files, among other things. In order to get the most out of this batch file, it is recommended that you also download Handle.exe as well as mailsend1.17b14.exe, being sure to rename it to mailsend.exe. These executables should be saved either in a directory that is in your PATH or in the same directory as dumpcap.bat itself. (GPL, Windows)
maxfiles.bat A batch file to limit either the number of files in a directory to a specified limit, or the total disk space consumed by those files or both.
menushark, a Bourne shell menu script to allow users to employ the use of tshark by answering a few menu questions. The script also gives you the command that the menu system has made to try to teach you how to use tshark at the command line.
mpeg_dump, a Lua script that adds a Wireshark extension to dump MPEG-2 transport stream packets (ISO/IEC 13818-1) from a network capture to a file, for example, to extract one or more mpeg PIDs that were transported via UDP unicast or multicast.
osXextraction, a macOS bash script to extract particular packet types from a capture file (NOTE: it's not very macOS-specific - some small changes should allow it to work on other UN*Xes, and would probably allow it to work on Windows with Cygwin as well.)
RtpH263DumpScript, a perl script to dump H.263 video data
update-ws-profiles and update-ws-profiles.bat automate changing strings in a collection of Wireshark profiles, e.g. changing "gui.filter_expressions.expr: eth.addr==11:22:33:44:55:66" to "gui.filter_expressions.expr: eth.addr==66:55:44:33:22:11"
dumpcapui - A GUI front-end for dumpcap.exe that helps you in setting up dumpcap.exe captures and allows storing and retrieving of those settings at a later time. (Windows)
Packet Dump Decode (pdd) is a simple and convenient GUI wrapper around the Wireshark tools to convert packet hexdumps into well formatted xml (viz. text2pcap and tshark). Using pdd, you just need to copy-paste the hexdump into pdd and hit the "Decode" button (GPL, Linux/Win32)
Packet Hexdump Decoder (phd) is a web-based utility that uses Wireshark tools to decode packet hexdumps online.

Raw USB traffic can be captured with Wireshark currently only under Linux, see CaptureSetup/USB. If it's an Ethernet (or any other network related) USB adapter, Wireshark can capture e.g. Ethernet traffic from that USB device if the platform supports it (which it usually will do). On Win32 you can however try:
