Omi Lua Wireshark Dissectors

Omi Lua Wireshark dissector scripts provide easily customized cross platform dissection solutions for viewing common binary exchange protocols.

For more information on lua dissectors: How Lua fits into Wireshark

Usage

To dissect packets, place lua script(s) in the wireshark plugins directory.

The standard user path on a windows install (please create the plugins directory):

%APPDATA%\Wireshark\plugins\

On a linux install use:

//usr/share/wireshark/plugins

For configuration information: Wireshark Plugin Configuration

Note: Some packets contain enough information to programmatically determine the correct protocol specification and/or version at runtime. Many do not. If you add multiple dissectors to your plugins folder, wireshark will dissect each "conversation" based on the first matching protocol. In these cases, please manually select protocol dissector using Analyze | Decode As….

Development

Updates are greatly appreciated; however, this entire repository is source generated...including the words you are reading right now. If you wish to suggest script updates, the recommended process is to create an issue with changes and explanation. Time permitting, we will update the models and regenerate.

Note: Our dissector model is still under rapid development.

Testing

Please report any dissection errors as issues. Include a small note on the protocol and version, and a minimal capture demonstrating the problem. Also consider including a link or pdf specification documenting the correct behavior.

Production packet captures are required for protocol verification. If your organization has the rights to packet captures, and you wish to make the world a better place, please post captures to this project.
