Wireshark · Ethereal-dev: [Ethereal-dev] My dissector and subdissector question

[Sean Mistry <therealdizza@xxxxxxxxx>]

Hi all,

 

I'm creating 2 proprietary dissectors that reside over TCP.  I have created and successfully installed both dissectors and its even recognized.  However, the problem that I have is that it my second or subdissector doesn't respond when the first dissector is load with the captured data. 

 

 

 

(The data is fine, not corrupted at all.)

 

When my first dissector gets called here's how I do it:

 

 

in my proto register

 

 ...(&hf_super_prefix, {"Superset Protocol", "super.prefix", FT_UINT32. BASE_HEX, NULL, 0x0, "", HFILL}}

 

subdissector_table = register_dissector_table("super.prefix", "SUPERSET PREFIX", FT_UINT32, BASE_HEX);

 

register_dissector("super", dissect_super, proto_super);

 

 

in my proto_reg_handoff routine

 

dissector_handle_t super_handle;

super_handle = find_dissector("super");

dissector_add("tcp.port", 8000, super_handle);

 

This works just fine.

 

In my subdissector I have:

 

in my proto_reg_handoff routine

 

dissector_handle_t subset_handle;

subset_handle = find_dissector("subset");

dissector_add("super.prefix", 3A3A3A3A, subset_handle);

 

Am I supposed to set the value for super.prefix somewhere in its file?  If so, how?

 

Please and thanks,

Sean
