Wireshark-dev: Re: [Wireshark-dev] Nested ASN1 dissector was Re: Hello to the list anda nested
Hi,
Sorry
can't help, I build on Windows :-)

Hi,
I was actually using a hand made Makefile as
of http://wiki.wireshark.org/ASN1_sample, I was not using the
autoconf+automake chain used by the wireshark sources. I have decided to start
from scratch and to switch to the common behavior. These are the steps I
think I will follow:
1)Copy from the asn1/tcap directory the Makefile*
2)Merge the two asn into one including both
3)Write a simple cnf file
4)Follow the usual compilation chain
Actually I already have problems in correctly using the build chain because
the Makefile is not created, I don't see it in the list of the created ones
while configure is running.
I hope you will have a few minutes to give me your suggestions
Thanks
Gaetano

[Wireshark-dev] Hello to the list and a nested dissector
Hi,
Well
in makefile.common in your asn1/foo ( your asn2wrs generated dissector)
try:
:
ASN_FILE_LIST = yourtcap.asn
\
foo.asn
:
Hi,
well, I think you are right. What I am actually trying to do this morning
is to merge the ASN code from the TCAP dissector (your code!) and the one from
the protocol I need even I don't know exactly how to do it.
The actual application is a client towards a cluster of serves using this
protocol combination. It is built by means of an asn to c++ preprocessor applied
to 2 asn files: the TCAP one, very similar to yours, and another one with the
higher protocol but they are kept separated. Each outgoing message is assembled
building the header then appending a TCAP primitive built around a previously
constructed operation of the private protocol.
I am very new to the wireshark development world so I don't know how to
move myself well so thank you for the help you are providing.

Hi,
Perhaps you are better off including the relevant TCAP and ROS ASN1 code
in your ASN1 based dissector.
How is
the actual application built?
Using
a asn1 to target code generator? If so it should be possible to use the same
ASN1 files?

Hi,
my TCAP looks somewhat simpler:
Transaction Capabilities Application Part
begin
Source Transaction ID
Transaction Id: 43000004
Components: 1 item
Item: invoke (1)
........
Data (276 bytes)
so I have neither oid field nor the ACN.
Do you think there is an alternative?
Thank you for your time

Hi,
How
does the TCAP portion of your packet look?
Example:
Transaction Capabilities Application Part
begin
Source Transaction ID
Transaction Id: 2DB901
oid:
0.0.17.773.1.1.1 (dialogue-as-id)
dialogueRequest
application-context-name:
0.4.0.0.1.0.25.2 (shortMsgMT-RelayContext-v2)
:
In this case the GSM
MAP dissector has:
register_ber_oid_dissector_handle("0.4.0.0.1.0.25.2", map_handle, proto_gsm_map,"shortMsgMT-RelayContext-v2" );
Hope this
helps.

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
