I am new to the realm of REVERSE ENGINEERING.

I have taken up a small project..

I aim to develop a utility that will help to trouble shoot call processing failures in a cellular network.

I have with me the executable ( mc68k executable). It runs on a LUCENT implementaion of UNIX system based on 3b21d processor.

I want to look at the code mainly to understand what message is thrown under various conditions of call processing failures.


Could anyone help me with the forward path?????

best place to start looking is IDA. It can disassm a variety of executables, but I did not check if you strain is one of them. it also has an OK incorporated debugger, but doubt you would be able to run it on a win32 environment with your mc68k exe files.
Your best bet is looking for application development SDK and see if they have debuggers incorporated to them

I'm not really sure what your question is, but try to disassemble the executable with IDA, that's your best shot for executables of strange formats.

EDIT: Oh great, overtaken at the goal line again...

ida's debugger can only handle windows PE files
