Question 1: Write a JAVA Program to send a message from client to server and receive a response back using TCP socket programming. Objectives of this program: SI. No. Tasks Marks Make Use of Java TCP Socket Programming. It starts a server which will be always running listening to a port 5000 (Server.java). Client (Client.java) sends a number (message) to the server. If 1 the client sends any other character to server then the server should send an error message. Server receives this number and multiplies it by 2. Server (Server.java) sends back the result (message) to the client (Client.java). In case the number sent by the client was not a proper number, server (Server.java) sends back the message "Please send a proper number" to the client (Client.java). Write both client and server programs demonstrating this and mail me your files. 1 0.5 0.5 3 4 0.5 0.5 6. 1.5 7 1.5

In this assignment, you will develop a simple socket-based TCP program in C++ for a server that accepts lines of input from a client and prints the lines ontothe server’s standard output. Compile and execute your program. On any other machinethat contains a Web browser, set the proxy server in the browser to the host that isrunning your server program; also configure the port number appropriately.Your browser should now send its GET request messages to your server, and yourserver should display the messages on its standard output.Use this platform to determine whether your browser generates conditional GETmessages for objects that are locally cached

Solve this Question? Write a Java program to create a TCP Socket program to receive an input message from client socket, reverse the input message and send it back to the client. Note that the program should have the comments embedded in it to explicitly explain why that code is being used. Explain in detail the client process and the server process with reference to the code given by you for this task.
Description: In this assignment, you'll write two clients (Agents) that will communicate with a server that you will also write. On start-up, the client should be prompted to enter their connection code. Your client (Agent) will then open a TCP socket to your server and send a message (a string of characters) to your server containing their <Connection Code>. The first five characters of the connection code is a predefined set, while the last four is the <Agent Code#!>. <Connection Code>=<Predefined Charterers> + <Agent Code#> Below are the list of the predefined characters and agent code numbers you should use in your project: Predefined Characters: [AJK78, KTV90, NEL55, DFG28] Agent Code Numbers: 1. Agent A-(2975) 2. Agent B-(6144) Possible Connection Codes for Agent B: 1. AJK786144 2. KTV906144 3. NELS56144 4. DFG286144 Anyone of these codes should successfully identify Agent B. If the connection code is unknow to the server, it should close the…
In this assignment, you will develop a simple Web server in Python that is capable of processing only one request. Specifically, your Web server will (i) Create a connection socket when contacted by a client (browser) (ii) Receive the HTTP request from this connection(iii) Parse the request to determine the specific file being requested(iv) Get the requested file from the server’s file system(v) Create an HTTP response message consisting of the requested file preceded by header lines(vi) Send the response over the TCP connection to the requesting browser. If a browser requests a file that is not present in your server, your server should return a “404 Not Found” error message. Your job is to code the steps above, run your server, and then test your server by sending requests from browsers running on different hosts. If you run your server on a host that already has a Web server running on it, then you should use a different port than port 80 for your Web server. Make sure to test your…

Write this program in Python. Your task is to implement both the server and client parts of a chat program. You must use TCP sockets to provide the following functionality: The server should allow for multiple simultaneous clients (Multithread). Any client can get a list of all other connected clients from the server. The server should provide both clients sending to individual other clients, and clients sending to all other online users -- simultaneously. The server should support some other functionality like groups, where clients can join groups tracked by the server, and messages can be sent to all clients in the group. Other option to send files to other clients. Each client must have an ID; used for connecting with the server, in order the server can keep a list of all connected clients. The client should access all functionality that the server supports. Therefore it must be able to request a list of the IDs for all other connected clients, send messages to other individual…
Suppose we have a client Socket called surClient. Write java statements to do the following: a. Create the Socket object to make a connection to a server named host on port 8500, and Get the input stream of the socket client and Get the local port client is connecting from and Get the local address of the client
C Programming: Write a program that optionally accepts an address and a port from the command line. If there is no address and port on the command line, it should create a TCP socket and print the address (i.e. server mode). You can choose any port number for your server (>1024). If there is an address and port, it should connect to it (i.e., client mode). Once the connections are set up, each side should enter a loop of receive, print what it received, then send a message. The ping from the client should be sent before entering that loop to start the process. Otherwise both sides will sit and listen without getting anything. The message should be ping from the client and a pong from the server. In order to test this on one machine, you will need to run the same program twice (in two separate terminals). Run first in server mode, then run in client mode using the information printed from the server as your command line arguments. This is the output it must print out: Running…
Write a python program that creates TCP connection between server and client and do the following: (You need to use datetime, hashlib, random modules) 1.1 When the client connects to a server, it will send one of the following commands (‘time’, ‘md5 STRING’, ‘random’)1.2 The server will receive the command and based on the command will send back data to the user: 1.2.1. Time: the server will send back the current time using the datetime module. 1.2.2. MD5: the server will take the string along with the md5 word and calculate the MD5 value for it and then send the hash to the client. 1.2.3. Random: the server will generate a random number between 1,100 and will send it back to the user.
