Networking, TCP/IP requires one computer to function as the server and another to function as the client. The two computers must communicate using the same “language”. You will be building the server and the client.
Write the program in C
The Server
Must accept commands in the form:
PUSH “filename” fileSize <<<bytes>>>
PUSH means that the client will be sending you a file. You need to store it with the filename sent. You must expect and require fileSize bytes. Respond to the client with “OK”.
PULL “filename”
PULL means that the client wants this file back. Respond with the number of bytes (use stat()), and then send all of the bytes to the client. Then respond with “OK” (a different send()).
The server should take two parameters – the directory to work in and the port. The server should not shutdown. The server must have an accept() loop to allow multiple clients to connect (one at a time).
