A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number. Discuss about the different types of socket calls using in TCP &UDP.

- Computer Networking Assignment 2 Lab 2: Web Server Lab In this lab, you will learn the basics of socket programming for TCP connections in Python: how to create a socket, bind it to a specific address and port, and send and receive a HTTP packet. You will also learn some basics of HTTP header format. You will develop a web server that handles one HTTP request at a time. Your web server should accept and parse the HTTP request, get the requested file from the server’s file system, create an HTTP response message consisting of the requested file preceded by header lines, and send the response directly to the client. If the requested file is not present in the server, the server should send an HTTP “404 Not Found” message back to the client. Code Below you will find the skeleton code for the Web server. You are to complete the skeleton code. The places where you need to fill in code are marked with #Fill in start and #Fill in end. Each place may require one or more lines of code.…UDP Echo ApplicationA UDP Echo program is a simple network application that demonstrates the basicprinciples of UDP communication. In this program, a server listens for incoming UDPpackets from clients, and when it receives a packet, it echoes (sends back) the samepacket to the client. The client sends a message to the server, and the server returns thesame message. It's often used for testing network connectivity and understanding thefundamentals of UDP communication. (Answer the following question using python) Implement both the server and client components of this UDP Echo program whileadhering to the features outlined below. Please ensure that your implementation followsgood coding practices and provides clear prompts and feedback to the user, making ituser-friendly and robust. Please refer to the class example to guide your implementation. 1) UDP Echo Server Receiving and Displaying Messages: The UDP Echo server should be able toreceive messages sent by clients. For each…Computer Science Networks and should be done in C language. Create a UDP client and server program that not only is able to locally transfer files but it gives the client the ability to send multiple copies of the file to multiple servers. Once the server program is initiated, it waits until it receives client packets. It then reads and saves the payload of the packets. The client reads a file from the disk and sends it to each server over a UDP socket by breaking the file up into mtu-byte sized packets. Client needs to be concurrent in sending the packets to all of the servers using threads
- QUESTION 13 Fill the blank With the TCP server, there is a welcoming socket, and each time a client initiates a connection to the server, a new socket is created. Thus, to support n simultaneous connections, the server would need sockets. O n-1 On O n+1 0 1The University (U) has developed a new protocol, called UAPP, that is used by a client application on computers in its different branches around the world to send students information to a central server in the U campus in Kuwait. The TCP/IP stack is used by the protocol. Based on your strong knowledge of OpenSSL libraries, you have been hired by the U to pertest and configure the client/server applications so that all sessions between client/servers are became secure. After securing the application, a secure session and connection has been established. The following information is stored by the client computer for this session/connection: Session ID: id Compression method: null Cipher Suite: TLS DHE RSA WITH AES 128 CBC SHA Master secret: s Server random: Client random: Server MAC secret: Client MAC secret: Server encrypt key: Client encrypt key: The following figure shows the general operation of SSL record protocol: Draw a protocol…SMTP (Simple Mail Transfer Protocol) is the standard protocol for transferring mail between hosts. A TCP connection is set up between a user agent and a server program. The server listens on TCP port 25 for incoming connection requests. The user end of the connection is on a TCP port number above 1023. You have defined the packet filter rule set shown in the table below. These rules permit and/or deny inbound and outbound traffic between the user agent and the mail server. Describe the purpose of each packet filter rule in the table.

- Write a TCP_Client Socket, where • the client reads 89, 99, 100, 65 numbers from standard input sends to server via socket • the client reads, prints Addition results received from the socketThree-way handshake is used by a TCP client and a TCP server to establish a connection, as illustrated below: 1st: client:port1 -> server:port2, SYN 2nd: server:port2 -> client:port1, SYNACK 3rd: client:port1 -> server:port2, ACK When this client is performing scanning attacks, it will generated a large number of failed connections. In each failed connection, the three-way handshake fails to complete. People commonly use SYN together with the absence of its corresponding SYNACK in this same TCP session to identify whether this connection is failed. By investigating the failed connections, an engineer finds that in legitimate/benign cases, if the server does not return SYNACK to the client, the client will not send the ACK packet after SYNACK (e.g., the 3rd packet above). Therefore, this engineer suggests that we can count the failed connections based on the following rules without considering SYNACK:Three-way handshake is used by a TCP client and a TCP server to establish a connection, as illustrated below: 1st: client:port1 -> server:port2, SYN 2nd: server:port2 -> client:port1, SYNACK 3rd: client:port1 -> server:port2, ACK When this client is performing scanning attacks, it will generated a large number of failed connections.

- An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most significant bits are used as a network ID, and the 16 least significant bits are used as a host ID. However, the host ID cannot be all 0's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network?UDP is a message-oriented protocol. TCP is a byte-oriented protocol. If an application needs to protect the boundaries of its message, which protocol should be used, UDP or TCP?The scenario includes one DHCP server in an Active Directory domain. The server is configured to provide IP addresses to DHCP clients on two different subnets. The subnets are separated by a router that has DHCP Forwarding enabled. In this scenario, you use ten of the excluded IP addresses to configure servers and other devices with static IP addresses and five additional IP addresses are left available for static configuration of new devices that you might want to add in the future. Write up the Powershell script for the following according to scenario IP configuration: Installing DHCP role (DHCP1) Creating DHCP security group (your Arid Number) in DHCP1 Note: Security Group should create with your arid number.
