How do I go about adding a new protocol

  • retag add tags

I'd like to add the work ongoing here

https://djl-analysis.deepsymmetry.org...

into wireshark, so that CDJ packets are rendered as such. All packets have a magic number and hardcoded ports so they should be quite easy to spot.

I have a quick hunt around the wiki and src code but I dont see where to get started.

Is there a packet dscription format or do we write C/C++?

There are a number of options when adding a new dissector, some of them are discussed in my SharkFest presentation How to write a Dissector.

If using C (note C++ is not currently supported for dissectors) or Lua, then the Wireshark Developers Guide and the various README.xxx files in the source tree doc directory are essential reading.
