The purpose of this project is to implement a simple multithreaded FTP server based on message-oriented and client-server communication. You will need to implement this project using C or C++ based on Unix/Linux. Project Description: A FTP server supports the following three basic operations:  DOWNLOAD: the client can download a file from the server;  DELETE: the client can delete a file in the server;  RENAME: the client can rename a file in the server, Please implement the above three functionalities! You may start with the provided client.c and server.c program (please download them from the folder Project 1/socket programming). They list the basic program structures of the client and server using socket programming. The server should be able to support multiple concurrent operations using multithreaded architecture. You will also need to use multiple clients to test your simple FTP server. We have discussed the following slide. It illustrates the basic structure of a ftp server: Deliverables:  Source code of client-side and server-side programs;  README file containing instructions on how to compile and run your client and server-side programs;  A simple demo about how your ftp client and server interact. You may use a short video clip to record your demo and illustrate how to download, delete, and rename files on the server side. You may prepare any simple files on the server side for the demo purposes!
