- UDP Task In the program explained during the lab, in the client side The OS assigns the port number automatically. The client sends a line of characters (data) from its keyboard to server. Update the client side of program so that it takes 2 arguments The port it will bind to. The message that will be sent to the server. Keep the server side of program as it is Use the screenshots in the presentation as a reference check the testArg.py --> an example to show you how to use arguments TCP Task In the program explained during the lab the client sends only 1 message to server ‘hello from tcp client’ server responds with the uppercase message. Update the program / make a simple chat program so that Client can send/receive multiple messages to server. A special exit message is used to disconnect ‘Exit’. Each time client sends a message, server responds with a confirmation of receiving it and its length (use the screenshots in the presentation as a reference)…UDP Task In the program explained during the lab, in the client side The OS assigns the port number automatically.

Use InetAddress class to display the local host address over the console. Your program should also print the name of address. 2. Create your own MyNetworkingServer and MyNetworkingClient applications as following: The client send two numbers and the server sends back addition of the two numbers. Contents: 1. InetAddress class 2. Socket class 3. DatagramSocket class and DatagramPacket class
- Penetration programming Modify the script so that it also works interactively. Specifically, if no hostname is given on the command line, the program should interactively ask for a hostname, starting port, and ending port with three separate prompts, and carry out its scan using those values. After scanning finishes, the program should loop to receive another set of values, stopping only when the user enters a blank host name. If this feature is implemented properly, it will also allow you to run the script in ’batch’ mode, by “piping in” a plain text file with the hostname on the first line, start port on the second, stop port on the third, and repeating for as many hosts as you wish to scan. For example, if a file named hosts_to_scan.txt contains a list of hosts and ports in the proper format, the program should now work as follows: cat hosts_to_scan.txt | ./portscanner.sh The timeout argument should still work in this case as well: cat hosts_to_scan.txt | ./portscanner.sh -t 3…Execute the command to show the files that are needed for routing operation. Get theinformation about the various drivers and interfaces present in your PC.Linux Command Function ifconfig also: ifcfg, ifup, ifdown, ethtool, nm-tool /etc/init.d/networking restart ip link set down ip link set up The ifconfig command is a tool used to display and configure network interfaces. This command will display information about the network card, IP address, broadcast address, and network mask. It also shows how many packets were received and transmitted. There is also information about the loopback device (lo). ping The ping command allows the user to test whether or not a network connection is active, the speed of that connection, and how a network behaves given specific data loads. arpalso: arping The arp command by itself is used to view the information currently in the ARP table (Address Resolution Protocol). This table maps the IP address of machines on your network segment with their MAC address. hostnamealso: domainname, dnsdomainname The hostname command tells you what the hostname of your machine is set to. The…

Manage open and closed ports on the server from the client terminal (remember ssh).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!
- 2. A server was locally running on a system at port 1000. What changes do you need to make in the port ID when you are deploying the server with Heroku.The line that configures the host name for the computer at boot time can be found in /etc/hostname. True or False?Pseudocode Port Scanner INPUT : IPv4 address with its port range TASK/function : Try the Internet Protocol address with its a port range The software will attempt to find open ports on the particular pc within having a connection to every one of them as well as having any successful connection ports, trace a port as open.
