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

[yagvoc-web@xxxxxxxx]

Hi,

I think I don't have such an identifier (x.y.z.a....). I checked the ASN.1 definition and couldn't find any.

Is there any way to create a "local" one just to link the tcap to this protocol? Then, as far as I understand, I should call register_ber_oid_dissector_handle passing the OID  as parameter, right?

Thank you very much and sorry for this stuff that may sound banal

Gaetano

Hi,
Look at GSM MAP how it can be done. You have an OID for your protocol,
right?
Just register that OID with a callback and you'll be handed a tvb with
the data.

Anders

Thank you Anders for your answer.
I have already parsed the asn by means of asn2wrs, I have also developed
the dissection of the header, afterwards I use the call_tcap_dissector
function from the asn1/tcap dissector to have the TCAP layer decoded
and, in the end, I need to decode the TCAP component by means of my ASN1
protocol.
Now what I don't know is how to retrieve the Component content from the
parsed TCAP and pass it to the dissection of the inner protocol.

Thanks again
Gaetano
