This work deals with basic socket programming context. This root directory contains two main directory one for SERVER node and other for CLIENT node. Overall working is:

• The client will create/request a connection to the server
• After successfull connection client can send either get <filenames> or exit REQUEST
• get <filenames> will download files to directory CLIENT/downloads from SERVER/downloadable_files directory
• exit will close the connection
• Progress will be printed while downloading the file on both server and client terminals.
• Connection is basically made of type TCP/IPV4
• Error handling such as requesting missing files has been handled appropriately.

Follow the steps to run the code:

• Open 2 terminal windows

• Open SERVER directory in one and CLIENT in other.

• In SERVER directory run the following commands: gcc server.c -o server then clear;./server You will get output on terminal: server setup complete: waiting for connections...

• In CLIENT directory run the following commands: gcc client.c -o client then clear;./client You will get a red color prompt.

• Before running any command place some dummy files of your choice in directory SERVER/downloadable_files. I have already put a dummy file. Check it out.

• Your Client is now connected to the Server and go download the available files...
