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.
- Compile the respective programs. For e.g., using gcc:
gcc deliver.c -lpthread -o deliverandgcc server.c -lpthread -o server - Get the current local IP . For e.g., using curl:
curl ifconfig.me - Run the compiled
deliverandserverprograms on the same network
Use the following syntax to run the programs:deliver <local IP/server address> <port number>andserver <port number> - Use the following command in the running instance of
deliver:ftp <filename> - 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
