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…

- The netstat programme, available for Linux and Windows, provides a list of active network connections. Describe how to use this command to identify whether a web page is not terminating connections or, if connection pooling is being used, is not returning connections to the pool. You may do this by looking at whether or not the connection is being returned to the pool. There is a possibility that connection pooling will not immediately terminate the connection.arrow_forwardModify 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,…arrow_forwardThere are two files, PingProgram.docx and GetHostByName.docx. PingProgram needs an IP address to work, and doesn’t use URLs, as per the example below. GetHostByName will return an IP address given a URL, also shown below. GetHostByName takes in a URL and a port number. Rewrite PingProgram to do the following: 1.Accept either a URL or an IP address as an input. 2.Ping the requested server 3 times instead of once. 3.Present all 3 round trip times, along with an average round trip time.arrow_forward

- The netstat command (available on Linux and on Windows) shows the active network connections on a computer. Explain how this command can be used to find out if a particular web page is not closing connections that it opened, or if connection pooling is used, not returning connections to the connection pool. You should account for the fact that with connection pooling, the connection may not get closed immediately.arrow_forwardSimilarly for /var/log/btmp type man lastb and find the purpose of btmp file linux redhat command onlyarrow_forward
