Week 3 Cisco Switching Worksheet

A merchant uses the e-commerce platform by logging in the platform with username (merchant_email) and password (merchant_password). Construct code segment to illustrate the change of application’s state for log in and log out using session through controller routes of the login logic. While merchant is in “logged in” state, merchant will be redirected to homepage and login page if the merchant is in “logged out” state.

How does a server know that one of his remote objects provided by him is no longer used by clients and can be collected? How does Java RMI handle this problem and what alternatives are there? What is the purpose of an Interface Definition Language? Why does CORBA not just use the Java interface construct? Two remote objects are related and should be updated in one operation. What kind of service do you need for this if you assume that both objects can be on different systems and that multiple operations can happen concurrently? The Lookup operation performs a single-level lookup, returning the Unique File Identifier (UFID) corresponding to a given simple name in a specified directory. What is Network File System deviate from one-copy file update semantics? Why should UFID be unique across all possible file systems? Write a simple java program to implement RMI.

Computer Science C programming Develop a proxy HTTP server that can accept HTTP requests from clients and convert them to HTTPS request to the web server. The HTTP request can be filtered based on an access control list. The requests can be generated by any web client, such as the curl command or a web browser. the proxy converts plain text HTTP requests from a client to HTTPS requests and then returns the responses to the client. Main objective is to create a proxy HTTP server that converts cleartext HTTP requests from clients to HTTPS requests to servers and vice versa for the responsesresponses.

What is the purpose of the remote interface when implementing RMI, explain the requirements that should be satisfied by the of Interface?

Today I was working with the singleEmailMessage class of salesforce and I want to set a default Email address for the same use case. Can you please suggest how I can do this task and get this issue resolved I have come to know to use org-wide Address. Please brief what is about it. both singleEmailMessage class and org wide address. Not the coding part just tell in bried

In this assignment, you will develop a simple Web server in Python that is capable of processing only one request. Specifically, your Web server will (i) Create a connection socket when contacted by a client (browser) (ii) Receive the HTTP request from this connection(iii) Parse the request to determine the specific file being requested(iv) Get the requested file from the server’s file system(v) Create an HTTP response message consisting of the requested file preceded by header lines(vi) Send the response over the TCP connection to the requesting browser. If a browser requests a file that is not present in your server, your server should return a “404 Not Found” error message. Your job is to code the steps above, run your server, and then test your server by sending requests from browsers running on different hosts. If you run your server on a host that already has a Web server running on it, then you should use a different port than port 80 for your Web server. Make sure to test your…

Please build a web server on your Raspbery Pi virtual host and publish a dynamic website that shows the characteristics of your virtual system and data about you as a current user i.e. Web page with information about the version of the operating system, what modules are configured and working, which interfaces are included (HDMI, USB, etc.), user name, time login etc. (at least 6 parameters).   Complete the web page with a survey for the loT class!   You have complete freedom for a design of the web page!

Can someone help me with the following, it's revision for an exam I'm doing. If your explaining it could you please provide detailed steps of why you did what you did so I know how to do it if it comes up in the real thing!  Thank you so much! :)   An IT administrator is interested in studying server traffic. He believes that the time (inminutes) between requests being sent to a server can be well modelled using a Weibulldistribution with parameters α = 2 and β = 1 b) The median arrival time is defined to be the time for which the probability of beingless than this value is 0.5. Calculate the median time between requests

1 . One of the responsibilities of the Controller in MVC is to Select proper Models for Views  True  False 2. When MVC is applied to a Web service only, the Controller MVC component is present.  True  False 3. Web services serve their data to a browser.  True  False 4. One of the responsibilities of the Controller in MVC is to Displays data to the user  True  False 5. With Web API controllers a route like /home/index tells us the Controller class name and the action method name.  True  False 6. The most commonly used format for modern Web Services is JSON.  True  False 7. One of the responsibilities of the Controller in MVC is to Connect to the database engine  True  False 8. It is possible for return type in the asynchronous method to be a void .  True  False

You are required to write a Spring Boot  + SpringMVC based application that handles a sample request given below and returns the additional parameter sent as part of the request:   http://localhost:8080/greeting?name=ali&salary=35000 The request should hit a MVC based Controller within your spring application (for get request type) and return a view (greeting the user) that may be JSP of Thymeleaf templating engine.

What actually serves as the remote interface's function in the RMI implementation? What prerequisites must be satisfied in order to utilize the interface?

Hi please assist thanks

Computer Science Control an LED Remotely using TCPDUMP Must be implemented on the RPI 3B+ using a shell script. -In this project, write a shell script that when the PI receives a ping command with a specific byte pattern then it must turn on or off an LED. For example, if the ping command’s pattern is “aa ae” then the PI must turn on the LED. If the ping command’s pattern is “ab ae” then the PI must turn off the LED. If the ping command’s pattern is anything else, then the PI should do nothing and only print on the terminal that a PING message was just received.

Q1

A company has implemented a discretionary access control system for important documents and programs on a shared Linux server. Figure 1 shows the current implementation of the DAC system. It only applies to the directory /opt/company (you can ignore all files/directories that are not within this directory). The list of users is shown in the output from the firstls command; the members of each group is shown in the output of the tail command; the permissions are shown in the output of the second ls command. Assume the files are the objects, the subjects are the five users and there are four access rights: own, read, write and execute. Refer to Figure 4.2 and Table 2 in the textbook and complete the following subquestions I. Draw the Access Control Lists that illustrate the implementation on the Linux server; II. Draw the Capability Lists that illustrate the implementation on the Linux server; III. Build the Authorization Table that illustrate the implementation on the Linux server.

If the mode of an interface is Full- duplex, what does it mean? O a. Delay in sending or receiving data O b. Receive and send data at same time O c. There is no such feature called Full-duplex o d. Receive and send data at different times

The URL Connection class can be used to read and write data: Select one: a.To the specified resource referred by the HttpResponse and the URL b.To the specified resource referred by the URL c.To the specified resource referred by the HttpServer and the URL d.To the specified resource referred by the ServerSocket and the URL

Function: A client can chat with the server, with input in the screen, and output the other side's replies. No GUI needed.  Keypoints: TCP socket is used for both sides. Both sides open two sockets, one for sending, while the other for receiving.  IN JAVA OR C/C++ with both client code and server code

An AWS administrator has been given a requirement to configure a notification mechanism for the Developer team for their CICD pipeline. This notification need to be customized with a particular format and should not contain the default AWS formatted text. Which of the following is the correct method to implement the above requirement? Use SNS APIS to customize the message output to send the custom data to the recipient Use SNS to trigger a Lambda function which can extract the required values and construct a custom message, Use SES to send the customized message Use SES directly as the notification mechanism which can be customized based on standard Email templates O Use SNS to trigger an SES API which can extract the required values from message and send custom emal

If we want the system give a signal to the client when a message from the server is received, what should the program do? Indicate the advantages of using the Observable pattern and Adapter pattern in this design.
