Answers

Answer:

ARPANET

Explanation:

ARPANET was the name of the earliest iteration of the internet.

What is ARPANET?

The first open packet-switched computer network was the U.S. Advanced Research Projects Agency Network (ARPANET). In 1989, it was ultimately deactivated after being put into use in 1969. The primary applications of ARPANET were in academia and research.

The Advanced Research Projects Agency Network, or ARPANET, was developed in the late 1960s and served as the first functional prototype of the Internet. ARPANET, which was first supported by the US Department of Defense, used packet switching to enable multi-computer communication across a single network.

The first distributed control network was the ARPANET. It introduced TCP/IP protocols initially. With the employment of these technologies, the Internet was essentially only getting started. It was created with the fundamental goal of facilitating communication among scientific users.

Thus, it is ARPANET.

4.) Food cost for your restaurant is about $.38 on the dollar. That means for every dollar
in sales, you spend 38 cents in food cost.
Figure out the food costs for the following days' sales:
Monday: $3,459.00
Tuesday: $2,976.81
Wednesday: $3,185.32
Thursday: $3,562.91

Answers

Answer:

38 cents on the dollar means that the cost is 38%. So for each of the costs, multiply by 0.38 (38%) to get the cost.

$3459*0.38=$1314.42

$2976.81*0.38 = 1131.1878 or about $1131.19

what version of vsftpd contained the smiley face backdoor?

Answers

Answer:

Chris Evans, author of vsftpd announced that the master site for vsftpd was compromised and that the latest version of vsftpd (vsftpd-2.3.4.tar.gz) was backdoored. The backdoor payload is interesting. In response to a smiley face in the FTP username, a TCP callback shell is attempted. There is no obfuscation.

Explanation:

The master site for vsftpd was compromised, and the most recent version of vsftpd has a backdoor, according to vsftpd programmer Chris Evans. The payload on the backdoor is intriguing. A TCP callback shell is tried in response to a smiley in the FTP username. There is no concealment.

What version of vsftpd had smiley face backdoor?

Vsftpd version 2.3. 4 that could be downloaded from the main site was found to have been compromised in July 2011. A ":)" smileyface can be used as the username when entering into a compromised vsftpd-2.3. 4 server, giving users access to a command shell on port 6200.

The idea behind the attack against VSFTPD 2.3. 4 is to send a specific sequence of bytes on port 21 to start the malicious vsf sysutil extra() function, which, if executed successfully, opens the system's backdoor on port 6200.

causes the backdoor to be opened, which causes a shell to start listening on TCP port 6200. After a client connects to it and disconnects from it, the shell stops listening. This might be used by a remote, unauthenticated attacker to execute arbitrary code as root.

Thus, The master site for vsftpd was compromised, and the most recent version of vsftpd has a backdoor.

Write a program whose input is a string which contains a character and a phrase, and whose output indicates the number of times the character appears in the phrase. Ex: If the input is: n Monday the output is: 1 Ex: If the input is: z Today is Monday the output is: 0 Ex: If the input is: n It's a sunny day the output is: 2

Answers

Answer:

import java.io.*;

public class Main {

public static void main(String[] args) throws IOException {

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

String s;

while ((s = in.readLine()) != null) {

int total = 0;

for (char character : s.toCharArray()) {

if (s.charAt(0) == character) {

total++;

}

System.out.println(total - 1);

}

Explanation:

We start the program by using the BufferedReader which will allow input from the user.

Then, we create a variable String that will take the input from the user.

Since the problem is asking us for the total number of times that the specified character appeared in the String, we will have to iterate over that String and count every time the character is found.

For this, I initialized an integer variable total, that takes count every time the character is found.

Using a for each loop, I converted the string to a character array (e.g. instead of a String "Monday", it will now look like {"M", "o", "n", "d", "a", "y"). It will iterate for each character it finds and checks if the character at position 0 is the same as the character at position i.

If the condition is true, then the total will increment by one.

But the problem is, since we converted the string into a character array to validate each character, the initial character will also add to the sum. So for "n Monday", it will take the first n, and add the total + 1.

Without specifying total - 1, "n Monday" will output 2 since there are two total "n".

There is a limitation, which wasn't specified in the problem statement anyway, but it's good to be aware of in case you need to solve it. If you want to check all of the characters that must equal the character you want to validate, irrespective of upper or lowercase, you will have to convert the string to lowercase first, so that the program will take the uppercase letters into account as well.

For that, before the for each statement, simply add s = s.toLowerCase();
