Wireshark-dev: Re: [Wireshark-dev] Problems in decoding two different protocol headers

We could get into the technical parts later, but in theory, you could legally challenge the creator of the dissector of X if they have provided you the dissector of X, but is not willing to share the source with you. This is in direct violation of the GPL under which GPL and all dissectors are released (AFAIK). If they gave you the dissector they have to give you the source if you want it.

I'll think about the technical challenge in a while, but probably someone will beat me to it.

Best regards,
Abhik.
PS: If you have some captures already, perhaps you could try to reverse engineer the headers you want as a start.

Hi ,

 

There are 2 protocols X and Y. X runs over UDP. Y runs over X. A payload packet consists some headers of X and some headers of Y.

I am dissecting Y, and X  has been dissected by somebody else , who do not wish to share the source code.

 

As per my understanding:

 

  1. There should be an identification number which identifies Y over X.
  2. There should be sufficient bit-wise information in Y which identify X headers and data .

 

But I did not get either of the information. Instead I have a document which describe some headers of Y which contain X data , without specifying the values.

I am not able to understand how can I integrate the other protocol with mine and test the complete packet containing both the headers.

 

BR,

Tarani
