Wireshark-dev: [Wireshark-dev] catapult_pcap
From: "SOLTANI FATEN" <Faten.Soltani@xxxxxxxxxxxxxxxxxx>
Date: Mon, 23 Mar 2009 16:33:35 +0100
Hi everybody
As you know, Wireshark is able to read a catapult format (DCT2000),
I want to know HOW? By conversion from DCT200 format to pcap format, or there is some modification which were made in Wireshark library to make it able to read this format?
I'm asking this question because I have a similer problem: I have to decode files issue from a local simulator. Bellow you find a sample of data that I have to decode with Wireshark.
Thanks for any help

In attachment possible fixup, (I've also changed some g_snprintf() to g_strlcat())
Could you review?
Cheers

1) I think it is. Within my proto_register_x2d routine, I call as follows to register:
if (-1 == proto_x2d)
{
proto_x2d = proto_register_protocol ("X2D Protocol", "X2D", "x2d");
}
Variable proto_x2d is a static int, initialized to -1. After the proto_register_protocol call its value is 78246 with the AMIN macro #defined and with it #undef-ed.
2) Desperation. I tried it both ways (static & non-). The change to static was in case there was some pointer set to the x2d_item somewhere within the macro-hidden part of the Wireshark code. I didn't want the variable to go out of scope if that were true. It appeared to make no difference.
3) Good suggestion. The two legs are close to identical right now. I'll try this and post afterwards.
Thanks for the quick response on this.

1) is proto_x2d well initialized ?
2) why use static for your variables ?
3) take the AMIN example and modify it step by step, you will find the problem
4) I have no idea

Possible but unlikely.
I'm not 100% sure, but for me fix_pointer() needs -fno-strict-aliasing.

http://www.gnu.org/licenses/license-list.html#GPLIncompatibleLicenses
search for Original BSD license

Yes but only two and three clauses BSD, not the original.

I'll try to merge it with
http://wiki.wireshark.org/Development/Optimization , this version is
already able to find 2000 DNS packets inside 7 millions packets in 1
second.

I'm not sure what you mean by "a problem of variables $... ".
Is there something that leads you to that ?
In any case, continuing the debugging, maybe some information as to the
issue can be gotten by trying (from the dos command line):
bash -o igncr make-tapreg-dotc xyz.c . tap-rtp.c
and then checking the contents of xyz.c
This runs the complete script which creates the tshark-tap-register.c
file (but just for 1 input file and with a different output file).
