Which of the following is NOT a basic operation of socket connections between two hosts ? Open a socket. Read from and write to the stream according to the server's protocol. Do NOT accept connections from remote machines on the bound port. Open an input stream and output stream to the socket.
For this lab, you will write a shell script called nethelper.sh that: 1. Reads in a list of hosts from a host file that is passed in as a parameter 2. Repeatedly, until the user selects quit (q), ask the user if the user wants to ping a host or look up a hosts DNS name 3. Once the user has selected an action, prompts the user for which host and then applies the action. Note that for the ssh action, the script must also ask the user for the user name that will be used to log into the host. Step 1 To accomplish step 1 above (reading in a list of hosts from a file), you will write a function called read_hosts. Functions in bash scripts have the following syntax: function name { # function body goes here } You can put any bash syntax inside the function as the function body. Also, note that the parameters to a function act like the parameters passed in at the command line. In other words, the parameters to the function are place in variable named $1, $2, and so on. So, how do you read the…
build a shell script that takes a domain as input and gathers as much information about it as possible using commands like WHOIS and dig the script should accept the following as input:▪ domain eg. yahoo.com▪ email address eg. bob@yahoo.com▪ URL eg. www.yahoo.com▪ the script is better if it accepts the following:▪ IP address eg. 98.137.11.63
Modify the server code so that it prints the client’s IP and port number when it receive a new connection. from socket import * serverName = 'localhost' serverPort = 12000 clientSocket = socket(AF_INET, SOCK_STREAM) clientSocket.connect((serverName,serverPort)) sentence = input('Input lowercase sentence:') byteToSend = str.encode (sentence) clientSocket.send(byteToSend) modifiedSentence = clientSocket.recv(1024) print('From Server:', modifiedSentence) clientSocket.close() from socket import * serverPort = 12000 serverSocket = socket(AF_INET,SOCK_STREAM) serverSocket.bind(('',serverPort)) serverSocket.listen(1) print ('The server is ready to receive') while 1: connectionSocket, addr = serverSocket.accept() sentence = connectionSocket.recv(1024) capitalizedSentence = sentence.upper() connectionSocket.send(capitalizedSentence) connectionSocket.close() from socket import * serverName = 'localhost' serverPort = 12000 clientSocket = socket(AF_INET,…

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…

Configure Manual IP address on your Linux Virtual Machine by modifying the network script file for the enp0s3 interface as follows: IPv4: 192.168.x.1 Netmask: 255.255.255.0 Gateway: 192.168.x.254 DNS: 192.168.x.1 X=the last 2 digits of your student ID. If the digits are 01 then use 101 or 02 use 102 etc. Capture the updated contents of the ifcfg-enp0s3 script file. Paste them in the following space: Display the history of commands in the terminal. Capture the screen and paste the output
