FTP Client & Server Implementation

Authors : Rolandas Burbulis, Siddharth Subramanian Course : 651- Foundations of Computer Netwroks

FTP Server : This file contains the implementation of the FTP server which can connect multiple clients but can handle only service one client at a time. The server can run only UNIX based or LINUX systems due to the implementation of the LIST command. You can use this server with an open source and free FileZilla client.
