You are managing an FTP server installed in Ubuntu Server. The server has created a very large log file, vsftpd.log. Which command is appropriate to search the log file for activity of the user charlie?
sudo cat /var/log/vsftpd.log
grep “charlie” /var/log/vsftpd.log
sudo grep “charlie” /var/log/vsftpd.log
cat /var/log/vsftpd.log
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.

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

- 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_forwardOn servers with Linux operating system, access logs are kept under which of the following directories by default?A) /var/log/B) /var/log/auth/C)/log/D)/log/auth/ Which of the following would an attacker prefer to run operating system-level code with MSSQL?A) MSSQL cannot run code at the operating system level.B) MSSQL agentC) xp_cmdshellD) There are no options.
