Research and build a chroot jail that isolates ssh users who belong to the restrictssh group. (You will also need to create the

restrictssh group). Next, install an ftp server and configure it to allow anonymous logins. Create a second chroot jail that can be accessed by the anonymous account. You will probably need to create several new user accounts to facilitate testing your setups.

Answer:

Explanation:

#!/bin/bash

# This script can be used to create simple chroot environment

# Written by LinuxConfig.org  

# (c) 2020 LinuxConfig under GNU GPL v3.0+

#!/bin/bash

CHROOT='/var/chroot'

mkdir $CHROOT

for i in $( ldd $* | grep -v dynamic | cut -d " " -f 3 | sed 's/://' | sort | uniq )

 do

   cp --parents $i $CHROOT

 done

# ARCH amd64

if [ -f /lib64/ld-linux-x86-64.so.2 ]; then

  cp --parents /lib64/ld-linux-x86-64.so.2 /$CHROOT

fi

# ARCH i386

if [ -f  /lib/ld-linux.so.2 ]; then

  cp --parents /lib/ld-linux.so.2 /$CHROOT

fi

echo "Chroot jail is ready. To access it execute: chroot $CHROOT"

For the following 4-bit operation, assuming these register are ONLY 4-bits in size, which status flags are on after performing t
m_a_m_a [10]

Answer:

All flags are On ( c, z , N  )

Explanation:

Given data:

4-bit operation

Assuming 2's complement representation

<u>Determine status flags that are on after performing </u> 1010+0110

    1   1

    1  0   1  0

    0  1   1  0

  1  0 0 0 0

we will carry bit = 1 over

hence C = 1

given that: carry in = carry out there will be zero ( 0 ) overflow

hence V = 0

also Z = 1      

But the most significant bit is  N = 1

Given two Strings String s1 = "11223351638791377189728193"; String s2 = "983763978669976862724569282405742578"; and String varia
inn [45]

Answer:

import java.math.BigInteger;  

public class Main {  

public static void main(String[] args)  {  

String s1 = "11223351638791377189728193";   String s2 = "983763978669976862724569282405742578";

BigInteger num1 = new BigInteger(s1);  

BigInteger num2 = new BigInteger(s2);  

BigInteger product = num1.multiply(num2);  

String s3 = product.toString(10);

System.out.println(s3);  

}  

}  

Explanation:

Because s1 and s2 contain large integers, the program need the biginteger module in other to compute the products of s1 and s2 when converted to integers.

This line initializes the two string variables s1 and s2

String s1 = "11223351638791377189728193";   String s2 = "983763978669976862724569282405742578";

The next two lines convert the two strings to BigInteger. This allows the program to multiply large integers

<em> BigInteger a = new BigInteger(s1);   </em>

<em>BigInteger b = new BigInteger(s2);  </em>

<em />

This computes the product of the two big integers

BigInteger product = num1.multiply(num2);  

This converts the product to String s3

String s3 = product.toString(10);

This prints s3

System.out.println(s3);  

}  

}

Differentiate among a color display, gray scale display, and a black-and-white display​
kotykmax [81]

<u>Answer:</u>

<em>Black and white</em>:

It has only two values namely black or white. The white colour in the image will be represented as “white” and other colour part will be displayed as black.

<em>Grey-scale: </em>

Again the white part does not have a change, the black and other coloured items will be displayed in grey.

<em>Coloured image: </em>

It would display the actual colour of the image. The number of colours and shades depends on the original image from where actually it has been shooted and it also depends on the quality of the camera.
