Re: Extcap

Unfortunately, I can't share the driver.
 
If these are "bugs", I can log them in bugzilla (as Extcap is now officially part of the Wireshark source).  I believe 
both issues could be tested with the extcap example provided (extcap_example.py), although if someone asked/needed it, 
I could probably write a newer/simpler driver that exposed these bugs (i.e. translate Python example to C)
 
Note that while the example "provides" configuration, it doesn't actually pay attention to it "coming back" (like my 
driver needs).  Not sure if there is something special about how to launch a Python app (ie example provided) in 
Windows that would cause different "Window" behavior than a Console App written in C(++) and not have the ugly console 
window pop up when you start capturing.

If these are indeed "intended limitations", than yes documenting on the Wiki would be a good start.

I created an Extcap driver in Windows and noticed a few things:

1. Configuration is only passed if I launch interfaceSettings from opening Window.  It is not saved or passed to driver 
every time.  Is the driver supposed to save the last configuration passed to it?

2. My extcap driver is a console executable that is not "hidden" and comes up over top of Wireshark while capturing 
(which is visually ugly).  Perhaps the Windows API used should be similar to dumpcap (CreateProcess instead of 
g_spawn_async).  It seems CreateProcess has the ability to hide dumpcap's console Window.
 
 
I wasn't sure if these were Bugs or Features and I needed to adapt my driver accordingly.  The overall functionality of 
Extcap is really nice though.
 





Are you planning to share (if possible) and document this somewhere, e.g. Wiki?
