- Q1) Which task is performed by the dynamic routing protocols? * a. discover end devices O b. update routing tables O c. propagate host gateways O d. assign automatic IP addressing Q2) Which of the following is a static routing feature? * a. Security increases because only the network administrator may change the routing tables. O b. Configuration complexity decreases as network size increases. O c. Routing updates are automatically sent to neighbors. O d. Routing traffic load is increased when used in stub network linksLinux 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.

- Q10/ write True or False answer for the following statements. Correct the false statements 1. DHCP allow host to statically obtain its IP address from network server when it joins network. 2. IPV6 addresses are 32 bits, while IPV4 addresses are 128 bits. 3. IPsec is standard for IP network security, available for both IPV4 and IPV6. 4. IPSec helps to create authenticated and confidential packets for the transport layer 5. ICMP does not attempt to make IP a reliable protocol. it simply attempts to report errors and provide feedback on specific condition.Shell Script # 5 - NetworkTest.sh Create a fifth script called (NetworkTest.sh). This script will have one subroutine. 1. The subroutine will check if the system is online (Connected to the internet). If the system is connected to the internet, then perform the following: Ping the loopback IP address. Ping the gateway with 8 packets each packet is 1KB. Query the Domain Name System to qu.edu.qa. Save the results in a file called /tmp/PINGRESULTS.TXT. ● ● Otherwise, perform the following: • Ping your local machine. ● Display IP configuration and Routing Table of your Machine. Store results in a file called /tmp/NETINFO.TXT Finally reboot the system automatically after 20 seconds.#find all IP addresses for invalid logins, then see which IPs are also used for scanning def compareInvalidIPs(): return True 3. The getinvalidLogins() method should find all IP addresses that are used for both invalid logins AND are blocked by the firewall. To get the invalid logins, you should use the log/auth.log file. For compareInvalidIPs, you should first extract all gzipped versions of auth.log* (meaning auth.log, auth.log.0, auth.log.1, etc.) using the extractLogFiles() method that you implement. Similarly, you will extract all gzipped versions of ufw.log* using the extractLogFiles() method for firewall logs. You will then compare the IPs found in each version. Here is the output for my solution code when executing the if __name__=="__main__" code branch. Your output should be similar.
- Computer Science Scenario: Using the iptables command, create a firewall for the local system that meets the following objectives, at least one identity-tagged screenshots are needed for each step: Allows incoming connections for the SSH and FTP ports from any system Allows incoming connections for the telnet port for any system in the 192.168.1.0/24 network Logs all other incoming connections Drops all other incoming connections by changing the default policy Note: Do not save the changes you make during this lab exercise.When writing code that uses a "socket" library, to set up a TCP socket the value : must be used. To set up a UDP socket, the value • must be used. SOCK_DGRAM SOCK STREAMThe following program sets up a single client/server connection. When the client connects, the server reads any incoming data as text and prints it out one line at a time. If the server receives the string “shutdown”, then it closes the socket and exits. Download this program Download this program into GCC and run the code. Then update your code to allow for the server to manage concurrent connections on the same port. Use IP address 127.0.0.1.
