Chapter 12, Problem 12.27HW

Some network programming texts suggest the following approach for reading and writing sockets: Before interacting with the client, open two standard I/O streams on the same open connected socket descriptor, one for reading and one for writing:

FILE *fpin, *fpout;

fpin = fdopen(sockfd, "r");

fpout = fdopen(sockfd, "w”);

When the server finishes interacting with the client, close both streams as follows:

fclose(fpin);

fclose(fpout);

  However, if you try this approach in a concurrent server based on threads, you will create a deadly race condition. Explain.

This question relates to Socket Programming in C. From the code shown in Figure 4write the part of the server code where:i) A socket is created.ii) The properties of the created socket are filled in. Use the last 4 digits of yourstudent ID (9 digit ID) as port number.iii) The created socket is associated with its properties using the appropriate system calland parameters.iv)Take the last digit of your student ID (9 digit ID); if it is an odd number you are going to writethe code for a TCP server from the listening socket and all the steps of code after iii)to allow the server to communicate with one client by receiving a request from theclient and sending the answer “I got your request!”. If the last digit of your studentID (9 digit ID, 123456789) is an even number, you are going to write all the steps of code from iii) for a UDPserver to communicate with one client by receiving a request from the client andsending the answer “I got your request!”.Notes:1. Inside the code you must add…
Language : C / C++ / Python Develop a simple Web server (parity generator) that is capable of processing the request from client. Create a socket connection, when contacted by the client the server has to process the request and give back the result. Client part The client has to send the data in bits (e.g 1100011000). It also has to send the number of frames it has to separate the data (e.g. 2 frames) Server part Server has to split the data into 2 parts (Frame 1 -> 11000; Frame 2 ->11000) and send back to the client. For each part server has to find the even parity and send
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…
