README - Wireshark Lua parser for OpenFlow 1.5

This is a largely incomplete Wireshark parser for OpenFlow 1.5. I started it as an excuse to get exposed to Lua, and because I found myself often struggling with the dissector which can be automatically generated using LoxiGen.

Right now only few messages are parsed, and I am picking which ones I'll be implementing next on a per-need basis.

Installation

1. Make sure Wireshark is compiled --with-lua support and that it can be run without root permissions
2. Download this code
3. Copy the main file openflow_lua.lua in the Wireshark plugin folder
4. Export the LUA_PATH to include the path to the folder where the original openflow_lua.lua is located. For Lua>=5.2 this environment variable would look something like this:

export LUA_PATH_5_2=/home/myname/wireshark_openflow_dissector/?.lua
