This project was done as a computer assignment for Computer Networks course at University of Tehran. The aim of the project was to implement an FTP server and client using sockets in C++.
The server uses two sockets, one socket for receiving commands from clients and sending response (command socket), another one for sending files (data socket).
Server uses select() system call to handle requests from multiple clients without blocking the server process. For sending files from server, a new process is created using fork().
Server reads some configurations from config.json. These configurations include a list of users and their passwords and data limits and admin status, ports used for two sockets, and a list of protected files that cannot be viewed by normal users.
First the project should be compiled using make:
$ make
then server and client processes can be started:
$ ./server.out
$ ./client.out
