Port Windows Simple Client / Server Software to Linux

I have an existing client / server set of programs written in C which work under Windows. The programs send TCP, UDP, ICMP or ICMPv6 packets based on the parameters in the input configuration file. I am attaching sample server and client files. The task is to port this code so that it works under Linux. I will test on a server running UBUNTU. Please provide an installation package for UBUNTU as well as an RPM package. I will pay at most $100 for this.
