Hello Guys,
I have successfully written a program that uses the Wireshark Lib to
dissect some packets.
The thing is, through the API I was given from my boss, I can only
receive informations from the 3rd layer (IPv4, IPX, ... layer), which
confuses the dissectors, and screws the dissection.
O
How do the 2nd-layer dissectors get called normally? Because thy
register themselves with Wireshark, saying that if "wtap_encap" (the
wiretap encapsulation) is a certain type, then call them.
for example, from packet-eth.c:
dissector_add("wtap_encap", WTAP_ENCAP_ETHERNET, eth_maybefcs_hand
Dear all,
Can anybody tell me that can we change wireshark io_graph plot into -ve x-axis
or in -ve y-axis?
Please guide me.
I am waiting for your answers.
Best regards

Hi Guillaume,
Perhaps if you can figure out how this mechanism works -
http://wiki.wireshark.org/HowToDissectAnything, you could use a
similar approach. You could also check wiretap/wtap.h to see if the
API you have been provided can produce frames in one of the known
types.

Hello,
I *kind of* get what you mean, but I really don't know how to do that.
Let me explain what I do:
I use the wireshark library to analyze the packets I send it. The main
call to the library is done in my code through:
epan_dissect_run(edt, &pseudo_header, FakePacket , &fdata, 0);
where F

I think I misunderstood you. I thought your packets started at IP or
IPX.
Argh, I just poorly explained myself: I was just confused with Ethernet
and IP.
So I confirm, I get only "data" from the 3rd layer (IP)
Actually, it will always be IP datagrams, so I don't have to bother with
IPX or other fancy 3rd layer protocols).
What I'd like to do now to start the dissecti
Hi
I am unable to launch wireshark.exe from C:\wireshark-1.0.0\ but able to
successfully do it from C:\wireshark-1.0.0\wireshark-gtk1
Or C:\wireshark-1.0.0\wireshark-gtk2.
Thanks

Hi
I'm not fully immersed of the details of the build process, but I think (well
know, but I'm a bit modest... ;) ) it has to do with dependencies. The

Dear Steve,
Thank you very much for you help.
Yes, I created gtk/export_object_smtp.c ,gtk/export_object2.c,
export_object2.h and packet-smtp.h similar to gtk/export_object_http.c

some thing unreadable characters.

In order to better help the end user reading captures, I'm trying to set hints,
when decoding problems arise, due to packet data.
My first attempt was using DISSECTOR_ASSERT(), but this causes a 'bug in
dissector'. After reading a thread the dev-archive, this is apparently by
design, but about
Hi,
The intention is to have Wireshark accept and process every network packet it
gets tossed. Still it's software written by humans, so certain cases aren't
handled. To cover these problems an exception mechanism was created. The
DISSECTOR_ASSERT() and MALFORMED clauses are really for exceptio
Hello all,
I'm trying to write the dissector for Cisco's ged125 protocol. Cisco
gave this as my first project. Anyways, I need some help. I'm confused
on the general process for writing the dissectors. (I have already built
wireshark) I have found skeleton dissector templates and they are pretty

"Based off of TCP" in what sense? If it runs over TCP, just as, for
example, HTTP runs over TCP, the TCP dissector will call *your*

Hi
Do you mean on win32 platform, in the main directory wireshark-1.0.0, the
wireshark executable which is created will not work as all the required dlls
are not copies to this directory and as a result on launching it complains
saying that "some dll files not found"?
Its works fine from gtk d
