File Transfer Network

Description

This is a file transfer network emulating FTP, built in C++. The server supports GET and PUT requests for clients. The negotiation/control port is decided through UDP, and the actual file transfer is done through TCP.

Main Usage

To compile the files and run the executables, run:

make
./server.sh <storage_directory>
./client.sh <server_address> <n_port> <command> <filename>

<storage_directory> is a local directory on the server's machine where files may be stored. In the demo, we use ./serverfiles.
<server_address> is the name of the machine that is running the server (localhost, if server and client are running on the same machine, or something like ubuntu2204-012.student.cs.uwaterloo.ca)
<n_port> is the negotiation port that the server opened, which it outputs to stdout as SERVER_PORT=XXXXX.
<command> is one of {GET, PUT}
<filename> is the name of the file to get from the server, or to put to the server.

Note: before this, you may have to chmod +x server.sh && chmod +x client.sh.

Other Usage

Some other ways to use this library, notably the client-side commands, include:

./client.sh <server_address> <n_port> <command> <filename> <receive_directory>

This defines the directory for the client to store and receive the files from the server in. By default, this is a local directory called ./clientfiles.

./client.sh <server_address> <n_port> KILL

This gracefully terminates the server.
