Using C/C, write a network echo server "echo_s", an echo client "echo_c", and a log server "log_s" that meets the requirements below. 1 "echo_s" should reply to any client connected to one of its ports with the same message it receives. 2 "echo_s" must support both TCP and UDP connections from clients, on the same port number. 3 Your echo server must accept messages on multiple well-known port numbers (max 3). The server must run from the command-line with the port numbers to listen on as the command-line arguments. At a minimum, there must be one port number specified. Here's the required command-line format (arguments between [] are optional): $> echo_s [ ] "echo_s" and "echo_c" should be tested by using the command "ne" (netcat). See more about "ne" in the unix man pages. Testing scenario are: 4- a. "nc" as client with "echo_s" as server b. "echo_c" as client against "ne" as a server. C. "echo_c" as client againt "echo_s" as server for example, "ne" can be used as a UDP echo server with the command: nc -e /bin/cat -k -u -1 1235 and as a UDP client with: nc -u 127.0.0.1 1235 See man pages for other uses 5 "echo_s" should be able to handle multiple clients, by creating multiple processes [hint: multiprocessing, fork, ..). 6 In order to keep track of every message it receives, "echo_s" will send the following information to the log server "log_s", on order to log it to a file: a. IP address of the client b. Timestamp (date+time) when the echo request was made C. The message received then echoed. 7 The communication between "echo_s" and "log_s" is made only in UDP, using port 9999. Both "echo_s" and "log_s" uses multi processing, in order to for their main process not to block. 8 "log_s" will log the information received in a log file called "echo.log". The following is a sample entries showing the formatting used: 2017-04-07 13:21:33 "Hi, this is me" was received from 10.12.32.15 2017-04-07 13:21:34 "I am just testing" was received from 11.3.2.115 2017-04-07 13:21:35 "OK, I am done" was received from 25.1.20.42.7 9 Submit all the necessary files: echo_s.c, echo_c.c, log_c, echo.log, and Readme. If you have additional headers or source file, add them too to your zip file.

The given statement "if all network traffic resides on the local LAN, configuring a default gateway is not necessary" is True because the traffic never leaves the local LAN so it does not have to pass through a router/default gateway to get to another network.

A gateway is a piece of hardware that joins networks with various communication protocols in a way that permits information to move back and forth between them. It both transmits the data and transforms it into a format that the protocols on the receiving network can use.

A default gateway is a router that links your host to distant network segments more specifically. Communications between a corporate network and the Internet can be transferred through an Internet gateway.

A gateway frequently serves as a protocol converter so that users can send and receive messages via the Internet since local-area networks (LANs) used by businesses sometimes employ protocols that are different from those of the Internet.

Answer:b

Explanation:

The three phosphate groups in this ATP molecule are referred to as high energy bonds because they release a lot of energy when they break.

When one phosphate group is removed by breaking a phosphoanhydride bond during the process known as hydrolysis, energy is released and ATP is transformed into adenosine diphosphate (ADP). Energy is also released, just like when a phosphate is taken out of ADP to make adenosine monophosphate (AMP).

When ATP is broken down, usually by removing its terminal phosphate group, energy is released. The energy is utilized by the cell to perform work, typically by means of the liberated phosphate attaching.

The likelihood that precisely 2 caps have been applied incorrectly is around probability and P = 0.356.

There is a 5% chance that the machine will misapply a bottle's cap.

P1 Equals 0.05 when expressed in decimal form.

The likelihood of successfully applying for the cap is then equal to p2 = 0.95.

The likelihood is as follows if we choose 20 bottles and just two of them have a cap issue:

P = 0.05^2*0.95^18

Due to the fact that two bottles fell into the 0.05 and 18 bottles into the 0.95

P = 0.0089

However, each bottle has 20 chances to be filled with that probability, thus the likelihood is:

Pt = 2*20*0.089 = 0.356

The likelihood that exactly 2 caps were applied incorrectly is around 0.356 if you randomly choose 20 bottles from the ones this machine produces.

The most frequent reason for SSL certificate failures is this. This error indicates that the SSL certificate's validity time has expired. Each certificate has an expiration date. Any certificates that are not still valid will be rejected by the client.

The validity periods are often no longer than a year. Therefore, it is simple to overlook updating the certificates before they expire. The browser checks the expiration dates of all the certificates in your chain, including the leaf, intermediate, and root certificates. Verify that the intermediate and leaf certificates are both current. When a browser obtains an SSL certificate whose validity term hasn't yet begun, they encounter the inactive certificate problem. To handle the certificates for your server, it is normal practice today to utilize a certificate manager. The new certificates, whose validity term begins at the moment of deployment, will be automatically deployed by the manager. The client will reject the certificate if the client machine's clock is 5 minutes out owing to misconfiguration or other issues.

Explanation: The correct code would be x = int(input("Enter a number")) print" "x" What happens if a user types in A?" Assuming the language is python

Answer:

If the user types in "A" as an input, the program will raise a ValueError exception, because the input "A" is not a valid integer. The int() function is used to convert a string representation of a number to an integer, and it raises a ValueError if the input string cannot be converted to an integer.
