Project for CIS 454 students:

Due Date: May 6 (Tuesday), 2008

1) On a DOS prompt, using the Windows tracert program, determine the route to each of the following

destinations. Perform the test at least twice at different times of the day, say morning and afternoon or

afternoon and night.

The destinations to test are:

Example:

Try to identify the path /hops the route takes to the destination. Then draw a map of the route linking the major hops (You may draw a free hand sketch or plot the route on a proper map).

You may like to use the free utility Visual Traceroute ( to investigate further.

So your answer should contain:

i) Record of the tracert run at two times of the day

ii) Explanation of the fields output by the tracert program

iii) Explanation of any time differences you may observe

iv) A map of the route

2) Use the ping program on a Dos prompt to ‘ping ‘ the following destinations:

a)

b)

c)

i) Use different options to the ping program to record times taken for a round trip

for the following packet sizes : 64 bytes,512 bytes and 1024 bytes.

ii)Discuss the working of the ping program with reference to the protocol it employs

and your observations about your findings about the times taken.

Example:

Ping with options and destinations will help you investigate any host (i.e. ping <options> destination)

3) On a Unix workstation in the lab Bu004 try out the following command:

netstat –i.

Then do a man netstat (the manual page for the netstat command) and read what the command does and what its options are. Record the output of the command for at least three machines: One Linux machine, one Sun machine and one SGI machine.

When you describe the output be sure to identify each field in the output.

4) Use the Unix command nslookup to lookup the following hosts:

Do a man of the nslookup command.

i) Record the outputs you get (You may use the Unix script command to record the output)

ii) Write a brief report on the working of the nslookup command and the outputs you get.

5)

a) If the two IP addresses:

129.10.147.32 and

129.10.148.85

are in the same subnet, what is the subnet mask of the subnet?

How many bits are being used for the subnet?

How many subnets are possible in the network?

How many hosts are possible on this network?

b) Discuss the Dynamic Host Configuration Protocol in a page.

Do the PCs in the Business labs (Bu004, Bu023) have static or dynamic IP addresses?

How can you tell? Do they have DHCP enabled?

Outline the methods you followed to determine that the PCs either had or had not DHCP enabled.

How would you turn off DHC, if it is enabled and provide your own IP address?

Outline the steps you would follow on a Windows-based PC for the above questions.
