- 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. OUTPUT : status of port (open/closed)By default, when configuring an IPv6 address, Windows 10 generates a random number to fill out the bits needed for the NIC portion of the IPv6 address. This security measure helps conceal your device’s MAC address, and further protects your privacy by generating a new number every so often. There may be times, however, when you need your system to maintain a static IPv6 address. To do this, you can disable IPv6 autoconfiguration using the netsh utility in an elevated Command Prompt window. Do the following: 1. Open an elevated Command Prompt window. 2. Enter ipconfig/all. What is your computer’s current IPv6 address and MAC address? Carefully compare the two addresses. Are they in any way numerically related? 3. To disable the random IP address generation feature, enter the command: netsh interface ipv6 set global randomizeidentifiers5disabled 4. To instruct Windows to use the EUI-64 standard instead of the default settings, use this command: netsh interface ipv6 set privacy…UDP PROGRAM The client sends a message “HI” to the server Once the server received the full message, sever responds with “Hello, What’s your name?” When the client receives the full message from the server, Client should be able to enter the name via the terminal and send the name to the server. When the server received the full message, server responds with “Hello 'name', Welcome To The Server”. “name” should be the one that is received form the client.
- Multiple IP addresses cannot be assigned to a single network connection in Windows. Yes or No is the response.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…A UDP server does not listen() for connections?
- The telnet program has been replaced by SSH for reasons of security. In particular, telnet does not use any encryption, making the network traffic it generates susceptible to sniffing attacks. To see how bad this can be, try the following steps: In the Wireshark window, above the packet list pane (above the top pane), you will see text entry field with ‘Apply a display filter…’ shown. Enter the value telnet in this field and press ENTER. In the packet list pane (top pane), scroll to the very top of the list and then right click the entry for the first packet and then select the Follow submenu and the TCP Stream menu option. A window is now displayed on the screen. Reflect on the information presented and consider the following questions: 1) Why do you think these results are there? 2) What does it say about the process you have gone through? 3) What differences would be observed if SSH was used instead? 4) Were any other protocols present in your network capture? What is the purpose of…Computer Science Using a for loop, create a ping sweep that records all the IPv4 addresses on your home subnet. You may not use nmap in your code. This is supposed to be a bash script btw.In Kali Linux using program proxychains. describe steps and show how to configure it and use it to connect to SSH on "IP address".
- When using Windows, it is not possible to assign multiple IP addresses to a single network connection at the same time.
