- Write a Java program to create a TCP Socket program to receive an input message from client socket, reverse the input message and send it back to the client. Note that the program should have the comments embedded in it to explicitly explain why that code is being used. Explain in detail the client process and the server process with reference to the code given by you for this task. Notice: I have need to send the string from the client, the server will reverse the string and send it back to the client, the client will display the reversed string. Output screenshots are important.n this assignment, you will develop a simple socket-based TCP program in C++ for a server that accepts lines of input from a client and prints the lines ontothe server’s standard output. Compile and execute your program. On any other machinethat contains a Web browser, set the proxy server in the browser to the host that isrunning your server program; also configure the port number appropriately.Your browser should now send its GET request messages to your server, and yourserver should display the messages on its standard output.Use this platform to determine whether your browser generates conditional GETmessages for objects that are locally cached Create an informal reportI need help starting my assignment. Write a program that optionally accepts an address and a port from the command line. If there is no address and port on the command line, it should create a TCP socket and print the address (i.e. server mode). If there is an address and port, it should connect to it (i.e. client mode). Once the connections are set up, each side should enter a loop of receive, print what it received, then send a message. The message should be “ping” from the client and “pong” from the server. In order to test this, you will need to run the same program twice. I had two command line windows open to run mine. Run first in server mode, then run in client mode using the information printed from the server as your command line arguments.
- 1 Problem In this problem you must program a simple TCP Service Scanner. Scanners are usually used to detect network services in the Local Area Network. You have to write a program that detects which services are available on a specific IP address range. For example, the machine 192.168.0.1 can hold a Web Server, an FTP server and a Mail Server; all these services are located on different Ports (80, 21, 25). The program must check a range of Ports and identify which service is available within a range of IP Addresses. After the application is finished, it has to write a report in a single text file, with the following format:IP AddressService 1 (Port)Service 2 (Port)IP AddressService 1 (Port) Unidentified services can be named as: Unknown Service. The application should receive 4 parameters: Start IPAddress, End IPAddress, Start Port, End Port I need to continue this Execution and report below - please let me know Execution Examplepython3 TCPServiceScanner 192.168.0.1 192.168.0.254 1…You need to write a C program that lists the TCP ports that are open on a given target machine. (An open port is a port number that a machine is actively listening on.) The program requirements are as follows: The program accepts on the command line the following arguments: o The IP address of the target machine. o Two integers (separated by space) representing the lower and the upper port numbers between which port numbers need to be scanned. For example, a command line similar to the following ./program_name 1.2.3.4 1 20000 means that your program should find and list all open TCP ports on the machine with IP address 1.2.3.4 in the range from 1 to 20000, inclusive. o If the target is up and running, the program’s output should look similar to the following Open TCP ports on ‘1.2.3.4’ are: 1 7 9 13 19 22 37 80 111 8090 o The program needs also to report whether the target machine is down or unreachable. Write your OWN code. You are not allowed to use libraries or tools developed…Done in C for a network programming client and server in udp Develop a client and server responsible for a file transfer utilizing UDP. the client sends a local file to the server and the server will then reassemble and save the file locally. You must also account for the packets being re-ordered or being lost in transit to the server for when a connection drops for example. If a file is dropped, print a line to stderr for it. The client must be started by the command: ./client server.ip server.port mtu winsz in_file_path out_file_path An example for the server and client starting up is ./server 9090 0 ./client 10.10.0.1 9090 512 10 dir/file outfile
- Hello. I need help developing a C or C++ program that simulate an 8-port Ethernet switch. The switch initially has no knowledge about the hosts connected to each port. It learns frame addresses and stores-and-forwards the frames. The input text file "in.txt" contains information of the incoming frames, one frame per line. There are 4 pieces of data per line: frame ID, arrival port, frame source address,and frame destination address. The frames arrive at the switch in the order of which they appearin the input file. Destination address "X" indicates a broadcast frame. Thank you! ********************PLEASE YOUR CODE MUST BE COMPLETE, COMPILE AND EXECUTE**************** The output text file "out.txt" has 8 lines. Each line lists all the frames departing from each port, here is an example: "in.txt" contains 5 incoming frames:F1 P2 B--AF2 P6 D--CF3 P5 E--BF4 P7 F--DF5 P6 D--X"out.txt" should list the departing frames on each port:P1: F1 F2 F5P2: F2 F3 F5P3: F1 F2 F5P4: F1 F2 F5P5: F1…Write a TCP/IP based client-server python code for a “Close Tender”. Thetendering process proceeds as follows: The server will think for an amountwithin 5000-6000 randomly which will be printed as “Proposed Amount” atthe server program. Randomly take the “Tender amount” for five users such asUser 1, User 2, User 3, User 4 and User 5 in the client side and send thosevalues to the server. The server will compare all user’s value with the“Proposed Amount” to find out the closest one, then, it will send a message“Congratulations!!! (****User name) got the Tender” to the client.Description: You are required to implement a server program that responds to both TCP and UDP requests from the corresponding clients. The service provided by the server is simply a substitute cipher/cryptosystem. The cipher replaces one character to another based on some key. The input message (plaintext) can be of any size but composed only of small-letter (abcdefghijklmnopqrstuvwxyz). The output (ciphertext) has the same size and composed also of small-letter characters. The key is limited to 7 characters (also small-letter). You need to treat each digit as a number according to its position in the alphabet. For example, a=0, b=1, …,z=26. To encrypt a message, you add a plaintext character with the corresponding key character (mod 26). The key might be repeated to match the length of the plaintext message. In the decryption, you subtract the corresponding key character from the ciphertext character (mod 26). Again the key might be repeated as necessary. For example, if the…
- Please solve it correctly and please provide explanation of your answers. Please answer parts g, h and i. A PC and a Web Server are communicating over a TCP connection. The PC had started the three way handshake with the initial sequence number of 3069 . The Web Server's initial sequence number is 4830 . The window size of the PC is 815 bytes and the window size of the Web Server is 463 bytes. Using the third TCP handshake ack segment the PC sends the http request of the size 396 bytes to the Web Server. Then the Web Server answers with 3 segments containing the requested data. The first segment size is 42 bytes and the second segment size is 276 bytes and the third segment size is 146 bytes respectively. The PC receives all three segments within the timer. But unfortunately the second segment was corrupted. So the PC immediately sends an acknowledgement segment. Assume that the PC uses Selective Repeat/Reject ARQ. g) The second segment from webserver was corrupted. So the PC…Please solve it correctly and please provide explanation of your answers.
