Hi,
I've been asked to write an app that connects to a program that I know
nothing about. The only information I have is that it's sending data to
a specific IP via UDP. The data is just some numbers, I think a pair of
numbers (floats maybe?). I've seen how to connect() via UDP but ...
My questions is, how do I go about writing for something like this if I
know nothing about the data and can't get in touch w/ the person that
does. I don't know the sizes and how the other app is sending them,
other than the above info? How do you accurately parse such data once
you have it in a buffer?
Any help, suggestions, tips, etc... much appreciated.
Get a sniffer or other network monitor, capture some packets from the
program in question and reverse engineer from there.
