Re: Heuristic check of T.125 dissector

[ronnie sahlberg <ronniesahlberg () gmail com>]

Wireshark has lots of reverse engineered protocols. So that should not stop you.

For example, the whole CIFS/SMB family of protocols used to be reverse
engineered, eventhough now in later times the documentation to those
protocols are now available so errors in the decoding can be fixed.


If the dissector is useful to others, then if it is based on reverse
engineering instead of official documentation,   include it.
An incomplete, reverse engineered, dissector is better than no dissector at all.
