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 which only purpose is to capture network traffic, while keeping advanced features like capturing to multiple files (since version 0.99.0)
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
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 Mac OS X bash script to extract particular packet types from a capture file (NOTE: it's not very OS X-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
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:

Intrusion Analysis / SQL Database Support
C5 SIGMA from Command Five Pty Ltd automates TShark (Wireshark) to load large quantities of packet capture data into a SQL database using an automatically generated schema. C5 SIGMA flattens the Wireshark protocol tree into a relational table structure useful for intrusion analysis and data correlation with other systems. It also enables SQL queries against otherwise unnamed text fields visible in the Wireshark protocol tree by intelligently generating human readable names. C5 SIGMA is free software, released under GPL.
