APCO 2P011 Lab 10


In this lab you will focus on learning the primary component surrounding local area network. A portion of the lab will focus on learning to trouble shoot the hardware and software components of a LAN.

Introduction & Startup (5 min)

Set up your Dell machines and boot into windows.

Exercise 1 (30 min)

Complete Exercise 9.1

Exercise 2 (40 Min)

Complete Exercise 10.1

Exercise 3 (20 Min)

In this lab you will be required to create your own patch cable Exercise 10.3. Creating a patch cable is not difficult, once 1 is created the process becomes more smooth. Your instructor will demonstrate how to assemble a RJ45 connector. After the demonstration each person of the team will be required to create 1 cable.

After the demonstration, create a patch cable with the materials provided. Once complete test the cable using your multi-meter.

Your instructor has a neat gadget called a cable tester, borrow it, and test your cable.

Plug your cable into your dell machine and the network jack on you work table.

Exercise 4 (30 min)

Install WinIPConfig software. It can be used in conjunction with or a substitute to some of the tools listed in the book. It is a graphical version of the ipconfig utility mentioned in the lab.

Find the values for the following:






Determining who owns that IP address. A utility which is part of Win 7 is nslookup (name server lookup). You can use the command line version of Win 7 or an online version http://www.zoneedit.com/lookup.html. Using either source determine the name of Like wise you can reverse the process and extract an IP from the name. Try it.

Exercise 5 (10 min)

Examining your network using netsh. What is netsh? it is the network shell program which allows an interface to to your networking configuration on the machine. A common problem with many windows machines is the loss of, or a corrupt TCP/IP stack. Using a netsh command, the stack can be restored,often saving a reinstall of the OS.

Open a command window, Start -> run -> cmd

type the following:  netsh int ip reset resetlog.txt

This tells netsh to look at the interface ip which is the tcp/ip stack and reset it. Output of the command is sent to a log file resetlog.txt. This command can often save hours.

Explore netsh by just typing in netsh. You will get a prompt netsh>. A ? will list the available commands. For example typing interface and then ? or help will list all the interfaces which netsh can communicate with.

See what ipv4 interfaces your machine has. Start netsh by typing netsh.  Type interface, to see what the interface command can do type a ?, this will list a series of command. The ipv4 command is one of these, type ipv4. By now you should see the following on your screen.

    netsh  interface ipv4>

show addresses then lists all ipv4 configurations you machine has. Try it.

Exercise 6 (20 min)

Find the ip address of Vaxxine.com, use nslookup.

Use tracert to trace the network response to Vaxxine.com. Did it work, why not?

Try tracert on a local machine, such as

Try ping on Vaxxine.com, then on, which one worked and why?

Is it wise to assign an IP address manually, at Brock or at Home? Why?
