Need help with only the implementation part which are the $.$c files Please don't just use A$.$I. to explain how its done. I would actually like to see the correct implementation.c files for the client, server and any other $.$c file needed in the implementation part of this assignment please Networking with TCP$.$ Create a client application and a server application to copy a file on the client computer to a file on the server computer and vice versa. This exercise mimics the old UNIX$/$Linux rcp remote copy command that allows users to copy files from and to remote machines $($note: this command does not exist on the VM$).$ Your programs will also bypass all the security constraints built into the rcp command. You WILL be strictly graded on HOW WELL YOU FOLLOW DIRECTIONS! Do not take any shortcuts. This project does NOT utilize threading.$$See also the Warning in Assignment $11.$ We will continue to use the loopback address. It is recommended you execute the server and client from different directories, as you do not want one process to be reading the same file as the other process is writing it$.$All reads and writes of file contents will be done in blocks. Define the block size as $1024$ bytes. $($Be sure to test your program with files larger than the block size.$)$ However, the VM will NOT allow you to transfer files over $7168($or $7$ blocks$).$Create a server that:$1)$ prompts the user for an address and a port on which tobind and listen $($or accepts these as command line parameters$)2)$ enters an infinite loop that$3)$ accepts incoming connections$4)$ reads the network input stream for the type of copy:client$-$to$-$server $-$ CMD$\_$SEND, or server$-$to$-$client $-$ CMD$\_$RECV and sends the proper response to the client $--$ CMD$\_$RESP; these message types should be defined in a $.$h header file; see the sample output and the recommendations for message types and structures below$5)$ if the copy type is from client to server the server enters a loop that reads the network input for the file contents, and writes the bytes read to the output file; if the copy type is from server to client: enters a loop that writes the file contents to the network output, and$6)$ when done closes the file and the remote sd and returns to step $3).$You MUST catch all possible exceptions at EVERY STEP, i$.$e$.,$ monitor the return value of all system calls, and if an exception occurs you must terminate the TCP connection$($using close $(2)$ on the remote socket returned by the accept $(2)$ call$)$ AND close the file before awaiting the next incoming request. All errors must be displayed with an appropriate error message.$$Sample server dialog for the successful copy from the client to the server:$$$ server $127\mathrm{.}0\mathrm{.}0\mathrm{.}15000$Server: listeningServer: Connected to $127\mathrm{.}0\mathrm{.}0\mathrm{.}1,$ port $53478$sd $=3,$ rem$\_$sd $=4$receive$\_$msg sd $=4$Server: Received message type $1$ from $127\mathrm{.}0\mathrm{.}0\mathrm{.}1,$ port $53478$:Server sends response: type $1,$ status $0,$ and file size $0$send$\_$mesg sd $=4,$ leng $=12$Server: response sentServer awaits datareceive$\_$data: fd $=5,$ sd $=4,$ size $=2433$receive$\_$msg sd $=4$receive$\_$data writes $1024$ bytes to file $($total $=1024)$receive$\_$msg sd $=4$receive$\_$data writes $1024$ bytes to file $($total $=2048)$receive$\_$msg sd $=4$receive$\_$data writes $385$ bytes to file $($total $=2433)$To server data transfer succeeded$$Create a client that:$$If invoked from the command line;

the compiler will look in the CMD for proj.h$).$There are several routines that are shared by both the client and the server:receive$\_$msg $()$ receives a single message from the networksend$\_$mesg $()$ sends a single message to the networksend$\_$data $()$ loops through reads on the file and sends $1024$ blocks to the networkrecv$\_$data $()$ loops through reads on the network and writes the blocks received to the filePut all of these routines in a separate $.$c file $($say sendrecv$.$c$)$; compile this file to an object file $($on the Linux cluster use gcc instead of cc$)$:$ gcc c sendrecv$.$cThis will produce the object file: sendrecv$.$o$.$Then compile your server and client with this file:$ gcc server.c sendrecv$.$o o server$ gcc client.c sendrecv$.$o o client$$
