Hello together,

im working on my own dissector in c and i want to generate/create error messages like timeout or outofrange or something like that. I would like to give the frames which i find these created errors some colors depending on the error. Is there a common solution maybe? Would be enough if you can give me the number where i can find something of the README.dissector, because i'm still a beginner and want to learn more about devoloping my own dissector.

Thanks in advantage

Robin

The Wireshark support for this concept is called Expert Info:

The general idea behind the following "Expert Infos" is to have a better display of "uncommon" or "notable" network behaviour. This way, both novice and expert users will hopefully find probable network problems a lot faster, compared to scanning the packet list "manually".

Unfortunately not documented in the usual places that I could see. Commits to fix this are welcomed.
