Wireshark · Wireshark-dev: Re: [Wireshark-dev] Hello to the list and a nested dissector

Hi,

Why reinvent the wheel?

Use the existing TCAP dissector and use asn2wrs to generate the ASN.1 based dissector.

Regards

Anders

Subject: [Wireshark-dev] Hello to the list and a nested dissector

This is my first message to the list, hello to all the members and thank you for your invaluable work.

Sorry if I quickly fall back to a development problem, hoping somebody can help me.

My goal is to write a dissector for  a proprietary protocol with a little complexity.

It is a TCP/IP based protocol with a fixed (6 bytes) length header followed by a TCAP message which component is an ASN.1 defined protocol.

I have been able, following docs and samples, to dissect the header (the easy work!) but now don't know how to go on. Should I call the existing TCAP dissector or write  new one with included the inner protocol?

Thank you in advance

Gaetano
