1 IntroductionThe objective of this project is to learn TCP client-server interaction using a socket interface in C programming language. After completing this Project, you will have a basic understanding of the steps required todevelop a networking application. 2 Project SpecificationIn this project, you are required to do socket programming in C language (Linux environment) to implementa pair of client and server that can achieve simple password verification to indicate the current market valueof the stock. Your client will send a pair of username and password to your server and your server willverify whether the pair of username and password is legitimate or not for retrieving the stock value. Assumethe only legitimate pairs of usernames and passwords that will be accepted by your server are as follows.

Servers can be designed to limit the number of open connections. A typical example, a server may wish to have only N socket connections at any point in time. As soon as N connections are made, the server will not accept another incoming connection until an existing connection is released. 4.3 How can you ensure that a binary semaphore is implemented in the above scenario?
Task 4 – Socket Programming in Mininet Complete Assignment 3: Mail Client of the Socket Programming Assignments found on Page 180 of the prescribed text book. Name your file mailstudentnumber.py The goal of this programming assignment is to create a simple mail client that sends email to any recipient. Your client will need to establish a TCP connection with a mail server (e.g., a Google mail server), dialogue with the mail server using the SMTP protocol, send an email message to a recipient (e.g., your friend) via the mail server, and finally close the TCP connection with the mail server. Your job is to complete the code and test your client by sending email to different user accounts. You may also try sending through different servers (for example, through a Google mail server and through your university mailserver). Run this server and client on the mininet topology created in Task Run wireshark to capture all network traffic, when executing the server and client Capture…
Winona has set up AppLocker rules to protect computers on the company network from being infected by malware. Despite this, one of the computers is infected by malware.

n this assignment, you will develop a simple Web server in Python that is capableof 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 filepreceded 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 shouldreturn a “404 Not Found” error message.Your job is to code the steps above, run your server, and then test your server bysending requests from browsers running on different hosts. If you run your serveron a host that already has a Web server running on it, then you should use a differentport than port 80 for your Web server. Make sure to test your program…
