Explain how the getAllByName() method could be used to print all hostnames of an ip adress 204.23.25.67 as a string in Java. Kindly give specific line of codes. Thanks
Many packets can travel over a link between two hosts at the same time. Please give a schedule of all the steps that need to be taken to finish one package. Do you think that one delay will take a set amount of time and that the other delay's length can change as needed?
Which JavaScript statement should you execute first to enable your program to send asynchronous requests to the server over HTTP? a. xhr.send(null); b. let myReq = XMLHttpRequest.open(); c. let myReq = new httpRequest(); d. let myReq = new XMLHttpRequest();
In which of the following applications, UDP is a suitable transport layerprotocol? (a)In SMTP, a user can send a long e-mail message, which may includemultimedia. When a user sends a message, the recipient does not expectto receive a response quickly. (b)A user needs to download a very large text file from the internet. Theuser doesn’t want part of the file to be missing or corrupted when he/sheopens the file. The delay created between the delivery of the parts arenot an overriding concern for him. (c)In DNS, a client needs to send a short request to a server and to receive a quick response from it. The request and response can each fit in one userdatagram.
The problem below involves the UDP protocol.DescriptionClientSend an integer in the range 0 to 100 representing a student’s score in COMP2602 to the server.Use a loop to send five score to the server in all. Each score is sent one at a time so that theserver can respond to each score sent.ServerThe server receives each integer score from the client and returns the letter grade for that score tothe client where it is printed. Note: THE GRADE IS PRINTED AT THE CLIENT.Grade scheme 0-49 F, 50-70 C, 71-80 B, 81-100 AYou may use any reasonable IP addresses and port numbers in your program.Notes: Name the client client.py and the server server.py
A UDP service FlagServ is running at flagserv.cse543.rev.fish:13337. This UDP service receives a target IP address from the user, and if the user is authenticated, it will happily send a flag (a special string) via UDP to port 13337 of the target IP. Your job is to write a program that retrieves the flag. Can u help solve this problem?
The following is a dump of a UDP header in hexadecimal format.CB840045001C001Ca. What is the source port number (you can write it in hexadecimal format)? b. What is the destination port number (you can write it in hexadecimal format)? c. Is the packet directed from a client to a server or vice versa?

can someone help me with this? I. Use Wireshark to capture the traffic when you visit a website. Open the captured traffic Client Hello of the TLS protocol and take a screenshot of cipher suites initiated by the client (which is your browser) II. Check the traffic Server Hello of TLS protocol. Display the cipher suite offered by the server and explain how the cipher suite will protect subsequent HTTP traffics (Application Data) between your browser and the server
An attacker tries to do banner grabbing on a remote web server and executes the following command:$ nmap -sV hackme.com -p 80 He gets the following output:Starting Nmap 7.90 ( http://nmap.org ) at 2020-09-26 22:47 ESTNmap scan report for hackme.com (108.58.137.114)Host is up (0.048s latency).PORT STATE SERVICE VERSION80/tcp open http Apache httpdService detection performed. Please report any incorrect results at http://nmap.org/submit/.Nmap done: 1 IP address (1 host up) scanned in 7.36 seconds What did the hacker accomplish? nmap can’t retrieve the version number of any running remote service. The hacker successfully completed the banner grabbing. The hacker should have used nmap -O host.domain.com. The hacker failed to do banner grabbing as he didn’t get the version of the Apache web server.
Suppose that the RTT delay between a client and an HTTP server is 30 msecs; the time a server needs totransmit an object into its outgoing link is 0.85 msecs; and any other HTTP message not containing an objecthas a negligible (zero) transmission time. Suppose the client again makes 100 requests, one after the other,waiting for a reply to a request before sending the next request.Assume the client is using HTTP 1.1 and the IF-MODIFIED-SINCE header line. Assume 50% of the objectsrequested have NOT changed since the client downloaded them (before these 90 downloads are performed)How much time elapses (in milliseconds) between the client transmitting the first request, and the completionof the last request?
If the URL is typed as liveexample.pearsoncmg.com/commo n/sample.mp4 without http:// in front of it, will it work?
