• Run server

gcc -Wall server.c -o server
./server <port> <max clients>

• Run proxy

gcc -Wall proxy.c -o proxy
./proxy <port>
...
show # prints the client and server IP addresses, ports and used transfer protocol (TCP/UDP)
save # (dis)ables the backup option, this is, saving the last sent file
losses <number> # define the percentage of lost bytes during an UDP transfer

• Run client

gcc -Wall client.c -o client
./client <proxy address> <server address> <port> <UDP/TCP>
...
list # sends a file listing request to the server
quit # shuts down the client
download <tcp/udp> <enc/nor> file_name # downloads a file from the server and saves it on downloads folder
