Hi all,
Greeting of the day.
I am new in wireshark development, can anyone help me how to add
a new protocol handling in existing wireshark source. I have downloaded the
source. Please let me know code tree I need to go through for enhancement for a
new protocol
Hi Anand,
the sources contain a very well written doc/README.developer text file.
You have checked out the sources, so you should have it there. It is also
readable online from the SVN repository:

Hi,
Note when writing code for inclusion in the project you are better off working
against trunk. I would advice

Hi,
Some random ideas that some one with unlimited time on their hands could dig
into :-)
Seriously - I thought I'd just scribble down some things I've idly been
thinking about to see if it spurs any interest in implementing them or why it's
a bad idea.

My link was for an svn client to retrieve the files. Your link is to see
the repository via viewvc in your browser. As as appropriate for your
needs, but as you were asking about svn revisions I thought you were
interested in the former.

Hi Anders,

Are you using SetEnv.cmd from the SDK? If so, there shouldn't be any need
to then call either vcvarsxxx.bat, SetEnv will do it all.
The approach, I've used for many years, is to make sure you have an SDK
installed (which has other benefits such as bug fixes, newer compilers and
libraries
Hi,
Can anyone give me thorough reference on how exactly
wireshark work while displaying packet on linux. Where do I start to get
insights of design of wireshark. What is the code flow, from which file I start

There are READMEs in the doc subdirectory.
README.developer is a good starting point.
Otherwise, most of the code is pretty straightforward so it shouldnt
be too hard to just read it.

Hi,
Can you please let me know how does it talk with raw packets.
Is it using existing TCP stack or is it directly communication with lower level
drivers like phy/Mac layer. Where do I find that code section where we

My use of the vcvars scripts may be obsolete, I was following setup

I'll try using just SetEnv.Cmd , thanks for the tip.
Hi folks,
I have been using the pcapng icmp2.pcapng (which seems to have an
error in each Packet Block in that the length of the packet blocks is
off by two bytes, it seems) to test my changes.
I now have Wireshark 1.7.2 (SVN Rev 42330) plus mods that can accept
icmp2.pcapng in via a pipe.

You're quite right, all I need is SetEnv.Cmd with the appropriate target as
the arg. Thanks!
I did run into one more issue, when I rebuilt everything for x64: When I
tried to start wireshark.exe I got an Application Error dialog, saying The
application was unable to start correctly

Hi folks,
The problem with my changes to support pcap-ng through pipes seems to

IIRC Wireshark gets the linktype of the interfaces BEFORE the capture
starts. But I never actually worked in this

Thanks, this is working just fine.
But in that case I suggest an update to README.developer as I copied the
