Packet analysis with Wireshark

• Install the Lua IEBUS/AVCLAN packet dissector to the Wireshark Lua Plugins folder
  • Look in Help > About Wireshark dialog, Folders tab, "Personal Lua Plugins". It was ~/.local/lib/wireshark/plugins for me, but it didn't exist until I manually created it.
  • Copy or link avclan_plugin.lua to the Wireshark Lua Pluginds folder
    • Linking is more convenient if modifying/developing the dissector ln -s $(pwd)/avclan_plugin.lua ~/.local/lib/wireshark/plugins/avclan_plugin.lua
• Install Julia and needed packages (I recommend using juliaup or an official binary from the Julialang website. Binaries from your distribution are typically out of date and/or built incorrectly.)
  • From this folder, start Julia with the local project environment using julia --project=@.
  • Run ] instantiate to install the necessary Julia packages
• Run julia src/pipepackets.jl | wireshark -k -i - to pipe packets logged by the Mockingboard over serial into Wireshark. If the Lua dissector is installed correctly, the packets should be correctly recognized and dissected as IEBUS/AVCLAN packets
