Query users and groups a) Login with all your new users (use the login command). Use "w" or "who" command to see current users. Compare the output format between the two commands. b) Use "whoami", or "who am i" command to see your own login. Compare the output format between the two commands. c) Search for users: how to search for a user using part of his login name? (Hint: use "grep".) Can you write a script to do it? d) How to list all members in a particular group? Can you write a script to do it?
Answers
(a) The "w" and "who" commands display information about currently logged-in users, but their output formats differ.
(b)Both the "whoami" and "who am i" commands provide information about the current user's login.
(c)To search for a user using part of their login name, you can utilize the "grep" command.
(d)To list all members in a particular group, you can use the "getent" command combined with "grep" and "cut" commands.
(a) The "w" command provides a more detailed output compared to the "who" command. It displays information such as the username, terminal, remote host, login time, idle time, and the current command or process being executed by each user. On the other hand, the "who" command provides a simpler output, typically showing only the username, terminal, and login time.
b) The "whoami" and "who am i" commands both display the username of the currently logged-in user. However, the output format may vary depending on the system and configuration. In most cases, the output will simply be the username of the logged-in user.
c) The "grep" command allows you to search for patterns within a file or command output. To search for a user using part of their login name, you can pipe the output of the command that lists all users to "grep" and provide the partial login name as the pattern. For example, if you want to search for a user with the login name "john" in the list of all users, you can use the following command:
command-that-lists-all-users | grep "john"
Replace "command-that-lists-all-users" with the appropriate command to list all users on your system.
d) To list all members of a specific group, you can use the following script:
#!/bin/bash
group_name="your_group_name"
members=$(getent group "$group_name" | cut -d: -f4)
for member in $members; do
echo "$member"
done
Replace "your_group_name" with the name of the group you want to list members for. This script uses the "getent" command to retrieve group information, then pipes the output to "cut" to extract the member usernames. Finally, it loops through the list of members and prints each member's username.

LCD stands for Liquid Crystal Display. So yes, what you're seeing is liquid. it's no longer contained where it needs to be.
Implement the function printTwoLargest that inputs an arbitrary number of positive numbers from the user. The input of numbers stops when the first negative or zero value is entered by the user. The function then prints the two largest values entered by the user. If fewer than two distinct positive numbers are entered a message to that effect is printed instead of printing any numbers. Hint: Duplicates will cause problems. Try to make sure that you find a way to ignore them.
Answers
Answer:
The function in Python is as follows:
def printTwoLargest():
chk = 0
list1 = []
num = int(input("Enter: "))
while num > 0:
for i in list1:
if i == num:
chk+=1
break;
if chk == 0:
list1.append(num)
chk = 0
num = int(input("Enter: "))
list1.sort()
if len(list1) >= 2:
print("Largest:", list1[-1])
print("Second:", list1[-2])
else:
print("Length of list must be at least 2")
Explanation:
This defines the function
def printTwoLargest():
This initializes a check variable to 0
chk = 0
This initializes an empty list
list1 = []
This prompts the user for input
num = int(input("Enter: "))
The following loop is repeated until input is 0 or negative
while num > 0:
The following for loop checks for duplicate
for i in list1:
if i == num: If duplicate is found
chk+=1 The check variable is set to 1
break; And the for loop is exited
The input is appended to the list if the check variable is 0 (i.e. no duplicate)
if chk == 0:
list1.append(num)
This sets the check variable back to 0, for another input
chk = 0
This prompts the user for another input
num = int(input("Enter: "))
This sorts the list
list1.sort()
This prints the two largest if valid user input is 2 or more
if len(list1) >= 2:
print("Largest:", list1[-1])
print("Second:", list1[-2])
if otherwise, this prints that the length must be at least 2
else:
print("Length of list must be at least 2")

write a second function called round2() that is similar to round1() except that it uses k2 and returns the concatenation of r2 and l2.
Answers
To write a second function called round2() that is similar to round1() but uses k2 and returns the concatenation of r2 and l2, we can follow these steps:
Start by defining the function header with two arguments, r1 and l1, which represent the right and left halves of the output of round1().
Generate the subkeys k2a, k2b, k2c, and k2d using the same process as in round1(), but using k2 instead of k1.
Apply the Feistel function using the subkeys k2a, k2b, k2c, and k2d, and the input l1 and r1. The output of the Feistel function will be the new left and right halves, l2 and r2.
Concatenate r2 and l2 to obtain the output of round2().
Here is the implementation of the round2() function in Python:
def round2(r1, l1, k2):
# Generate subkeys k2a, k2b, k2c, k2d
k2a, k2b, k2c, k2d = generate_subkeys(k2)
# Apply Feistel function using subkeys k2a, k2b, k2c, k2d, and input l1 and r1
l2 = r1
r2 = xor(l1, feistel_function(r1, k2a, k2b, k2c, k2d))
# Concatenate r2 and l2 to obtain output of round2
output = r2 + l2
return output
The round2() function takes the right and left halves of the output of round1() as input, along with the subkey k2.
It generates the subkeys k2a, k2b, k2c, and k2d using the generate_subkeys() function, applies the Feistel function using these subkeys and the input r1 and l1, and concatenates the resulting r2 and l2 to obtain the output of round2(). The output is returned as a single string.

Suppose you have a mixture of nickels, dimes, and quarters in a piggy bank and that mixture has a value of $3.50. If there are twice as many dimes as there are quarters and 15 more nickels than dimes, determine the number of each coin in the piggy bank.
Answers
The piggy bank contains 10 nickels, 20 dimes, and 5 quarters. Let's assign variables to the number of each coin: N for nickels, D for dimes, and Q for quarters.
We can create a system of equations based on the given information.
From the value equation, we know that 0.05N + 0.10D + 0.25Q = 3.50.
From the second statement, we know that D = 2Q (twice as many dimes as quarters).
From the third statement, we know that N = D + 15 (15 more nickels than dimes).
Substituting the second and third statements into the value equation, we get 0.05(D + 15) + 0.10D + 0.25Q = 3.50.
Simplifying, we have 0.05D + 0.75 + 0.10D + 0.25Q = 3.50.
Combining like terms, we get 0.15D + 0.25Q = 2.75.
Multiplying both sides by 20 to eliminate decimals, we have 3D + 5Q = 55.
Using the second statement again, we substitute D = 2Q into the equation, resulting in 3(2Q) + 5Q = 55.
Simplifying, we get 11Q = 55, which gives Q = 5.
Substituting Q = 5 back into D = 2Q, we have D = 2(5) = 10.
Finally, substituting D = 10 into N = D + 15, we get N = 10 + 15 = 25.
Therefore, the piggy bank contains 10 nickels, 20 dimes, and 5 quarters.

you are working as a cybersecurity expert in an enterprise. while examining the newly established enterprise network, you found that when a request to write data to the drive is made, the controller sends that request to each drive. when a read action is required, the data is read twice, once from each drive. which type of raid is used in the newly established network?
Answers
Based on the information provided, it appears that the enterprise network uses a RAID 1 configuration.
What is RAID 1?RAID 1 is a type of RAID (Redundant Array of Independent Disks) configuration in which data is mirrored across two or more drives, so that the same data is written to each drive.
This provides redundancy and improved data availability, since the data can still be accessed even if one of the drives fails.
In a RAID 1 configuration, when a request to write data to the drive is made, the controller sends the request to each drive, and the data is written to both drives simultaneously.
When a read action is required, the data is read from both drives and compared to ensure that the data is consistent and accurate.
The description of the enterprise network's behavior matches the characteristics of a RAID 1 configuration, so it is likely that this is the type of RAID used in the newly established network.
