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.
Summary
This configuration is applicable in most of windows operating system. In this lesson I used windows 10
version build 14393. In configuring static IP address we need to remember some key points such as,
gateway and dns ip address. We could not create different range of IP addresses that contrast to current
network configuration if we are going to connect our computer to an existing WAN. However, we can
skip DNS and default gateway if just wanted to test the connectivity of two or more different nodes in a
standalone LAN connection and without having router, gateway or any ISP modem
Task 1: Subnetting a Class A Address: You will determine the information needed for a class A network that is being divided into six network segments. The network ID of the class A address is 120.0.0.0. Take a few pieces of paper and calculate the new subnet mask, the network ID, the first valid IP address, the last valid IP address, and the broadcast address of the four subnets. Once you have calculated your answers, fill in the following table. Refer to the subnetting example in this chapter as a guide to help you calculate the answers.
