Wireshark · Wireshark-dev: Re: [Wireshark-dev] Omnivorous Shark

[mmann78@xxxxxxxxxxxx]

Without looking at the details of the patch, my thoughts are:

 

1. I like the fact that a "workaround" has been created for insufficient heuristics.  I just hope it doesn't have the unintended consequence of weaker heuristics being created.

 

2. What I don't like is getting non capture file support (hooks) "for free", therefore having Wirehark support non capture file types (outside of the handful that commonly come across network protocols).  I've been (slowly) working on separating "Fileshark" functionality from Wireshark with the distinct difference of "capture file" vs "non-capture file" (or treating capture file as binary).  Yes, writing a new GUI for non-capture files will be an arduous task (which is why I started with a command line interface to work out the architecture), but I still believe we want the distinction of "Wireshark" separate from "FileShark" and not have an "OmniShark" that does both just because the underlying architecture is generic enough to support it.  I'd prefer the geneic architecture (with some futher tweaking) just do "double duty" for separate applications.

Hello,

There is a need to have a feedback about my propose of change (extend)
default procedure of opening file in Wireshark. I propose add ability
to choose format. Default behaviour is still "Automatic". New is
component (GUI, list) where you can choose opening format.

Use case: For example heuristic for "mp2t" fail on file in format VWR
(VWR will be open as mp2t). Currently you are not able to open VWR in
this case. Patch add possibility to open this file.

Related to it is next patch:
https://code.wireshark.org/review/#/c/17/
Example BTSNOOP files:
https://bugs.wireshark.org/bugzilla/attachment.cgi?id=1427
https://bugs.wireshark.org/bugzilla/attachment.cgi?id=1426

First patch add possibility to open file in specified format, so there
is a case to open log file in "Fileshark" mode. Fortunately seems that
Wireshark is able to dissect header of file and all packet like normal
Wireshark mode.
