Fuzzing programs

[PastorTaz]

Is anyone out there fimiliar with Peach fuzz or any other fuzzer that I can use to fuzz a simple Linux program written in C? The program listens on an IP and port and then returns that value flipped around. If you input more than 100 letters it goes into a perpetual loop.

I need to completely crash the program. Does anyone know of a good fuzzer to user to do this?

Thanks,
