I would agree that a dissector table for the GUIDs is probably the best way to 
go. I also just created a GUID dissector table in my recent work with Netmon.  
grep "netmon.provider_id" for example of how to setup a GUID dissector table 
(it's much more straightforward than the DCE/RPC one)

Subject: Re: [Wireshark-dev] Best way to give configuration information to a 
protocol



Hi Juan Jose,

Hi all,


Which is the best way to pass configuration to a protocol? Do we have any 
builtin mechanisms? I tried to upload a patch using CSV at some point but it 
didn't succeed. So I wonder if there is any recommended way I can implement: 
table or list in the Preferences, XML file, CSV file...


My goal is to pass ("GUID", "plugin_name") pairs to the RTPS protocol so 
Wireshark knows dynamically what plugin it should call to deserialize data that 
is written by the DataWriter with id = "GUID". The GUID is part of the DATA 
packet and it is already dissected and known at that point.



A UAT dialog could be appropriate for your needs. Several dissectors are 
already using it and can be taken as an example (packet-ipsec.c, packet-http.c, 
...).
Or if the GUID / plugin mapping never changes, you could create a dissector 
table and have your plugin register to this table (see 
register_dissector_table() / register_custom_dissector_table() and the 
corresponding dissector_add_XXX() functions).



Best regards,

Pascal.
