Re: Packet Size limited during capture message

["Maynard, Chris" <Christopher.Maynard () GTECH COM>]

Brian,

The GPL does not extend itself beyond your Wireshark dissector, but whether you release your dissector to be included 
in Wireshark someday or use it only for your clients, it is still covered under the terms of the GPL.  As far as any 
Wireshark dissectors are concerned, they are all GPL'd no matter what.  Whatever other software you distribute to your 
customers has nothing to do with your Wireshark dissector so you are free to use whatever license you want for that, 
but the Wireshark dissectors must be GPL'd.  I'm not sure you understand this.

BTW, I (and many others I'm sure), are in the same boat as you.  I've written many Wireshark dissectors for my company, 
none of which have been released outside of my company because the protocols they dissect are all proprietary.  The 
dissectors are thus used internally only and therefore the source code need not be made available to anyone outside our 
organization.  This concept is covered in brevity here: 
http://www.gnu.org/licenses/gpl-faq.html#GPLRequireSourcePostedPublic.  However, that said, the dissectors I've written 
are still covered under the GPL per http://www.gnu.org/licenses/gpl-faq.html#GPLModuleLicense.  I do not wish to write 
my own proprietary protocol analyzer so I happily accept the terms of the GPL.

- Chris

Chris

I will have to look into why my dissector is crashing when I get the Packet Size Limited during capture message.

I am an employee of Dark Corner Software. I am writing the dissector for our clients that use our software.

I have fixed the license issue. Attached is the latest updated file that I am still working on.

We have open source software and closed source software. I am trying to get the open source dissector submitted through 
wireshark so it can become a part of the wireshark distribution (this is the attached copy).

Our closed source software is for our customers only. I have written a dissector for our closed source software for the 
client. This is where I am getting the "Packet Size limited during capture " message from.

Thanks,
Brian
