The goal of this project is to use UNIX sockets to create a server and client program connection that can transfer any type of file (binary file) across a local network.

1. Compile the respective programs. For e.g., using gcc:
   gcc deliver.c -lpthread -o deliver and gcc server.c -lpthread -o server
2. Get the current local IP . For e.g., using curl:
   curl ifconfig.me
3. Run the compiled deliver and server programs on the same network
   Use the following syntax to run the programs: deliver <local IP/server address> <port number> and server <port number>
4. Use the following command in the running instance of deliver : ftp <filename>
5. The server will receive the file from the sent packets and create a new exact copy of the sent file by combining the sent packets. The new file will be named new<filename>

• Uses a packet format and acknowledgement implementation
• Packets are sent as total_fragments:current_fragment:total_size:filename:filedata
• The file is fragmented if above the max fragment size and sent and split and reassembled at the server accordingly
• Client program reads data from the specified file and sends it to the server using the chosen UDP socket
• Server program reads the file name, creates a corresponding file stream and reads data from the packets to write to the file stream
