idl2wrs - CORBA IDL to Wireshark Plugin Generator


idl2wrs <filename>


idl2wrs is a program that takes a user specified CORBA IDL file and generates "C" source
code for a Wireshark "plugin".

This resulting file can be compiled as a Wireshark plugin, and used to monitor GIOP/IIOP
traffic that is using this IDL.

idl2wrs is actually a shell script wrapper for two Python programs. These programs are:

· wireshark_be.py

Contains the main IDL Visitor Class

· wireshark_gen.py

Contains the Source Code Generator Class

idl2wrs supports heuristic dissection of GIOP/IIOP traffic, and some experimental code for
explicit dissection, based on Object Key <-> Repository Id mapping. However, code for
heuristic based plugins is generated by default, and users should consider this the
preferred method unless you have some namespace collisions.


Currently there are no options. idl2wrs can be invoked as follows.

1. To write the C code to stdout.

idl2wrs <your_file.idl>

eg: idl2wrs echo.idl

2. To write to a file, just redirect the output.

idl2wrs echo.idl > packet-test.c


idl2wrs will look for wireshark_be.py and wireshark_gen.py in $PYTHONPATH/site-packages/
and if not found, will try the current directory ./

The -p option passed to omniidl (inside idl2wrs) indicates where wireshark_be.py and
wireshark_gen.py will be searched. This may need tweaking if you place these files
somewhere else.

If it complains about being unable to find some modules (eg tempfile.py), you may want to
check if PYTHONPATH is set correctly.

eg: PYTHONPATH=/usr/lib/python1.5/
