Hello,
Several years ago, there was some discussion on this list about a
Syncthing protocol dissector:
https://www.wireshark.org/lists/wireshark-dev/201811/msg00017.html
AFAICT, there still doesn't seem to be one. I'm new to Wireshark
internals (and pretty new to Wireshark externals, as well ;)), but I
thought I'd try my hand at writing one. I starting by writing a Lua
dissector for one of the Syncthing protocols:
https://github.com/tmo1/wireshark-syncthing-dissector
and it seems to work. If I'm not too daunted by trying to reimplement
it in C, would this be something of interest to the project?
