Hi,

Thanks for your responses. I think I would go for option#1 as a short
term solution and option#3 for long term as I want my changes to be
finally included in Wireshark. I have another query regarding option#1.
When I send customers a custom Wireshark Installer, do I also need to
have a version numbering different from official Wireshark builds? Is
there somewhere I have to let customers/people know that is our
"private" build as opposed to what has been offcially released by
Wireshark (like in the About box or something)?

Thanks for your help in advance.

Regards,

>#2 is a mixed bag.  Distributing code as plugins are probably more
"legal"
if you weren't willing/allowed to distribute >the sources, but that's
not a problem for you.  However, plugins tend to be problematic to
maintain. 
>There tend to be frequent changes in Wireshark that will break existing
plugins (so you'd potentially end up having to >compile a plugin for

with), and a lot of the >maintainers here aren't exactly a fan of them.
Don't expect a lot of support on getting them to work.  I'd probably
>stick with either #1 if this is just some really simple project and

if you want to do things "right" and save yourself work in the long run.

 

Why not go for #1 AND #3? 

Make a bug report with your dissector(s) and while waiting for
review/commit distribute a

Custom version.
