The Midterm

The midterm is also available in

Each question is worth a total of 10 points. Some questions may require you to use the 'script' command. If information is not available for a given section of the question, be sure to note that and explain why.

1. Using the altavista website, find the text of the recent Telecommunications Bill. Save the text to a file, edit out everything but the section(s) dealing with the V-chip. Email that to ma194=vchip@ms.uky.edu with the subject line "VCHIP"

2. Using nslookup, dig, traceroute and ping (as well as any other commands you find necessary), create a small network map of the following machines:

   	t2.mscf.uky.edu
   	t6.mscf.uky.edu
   	snoopy.ate.uky.edu
   	franklin.ate.uky.edu
   	thomas.loc.gov
   	c-span.org
   	whitehouse.gov
   	ftp.cc.gatech.edu
   
   

   Let each machine be a 'node' on the graph with at least the following information:

   	site name
   	IP number
   	Administrative or Technical Contact for the site or domain
   	any users logged in (if any)
   	The travel time for infomation between the site and pigpen.ate.uky.edu
   
   

   For the mapping aspect, plot the route between each of these machines and pigpen.ate.uky.edu, paying particular attention to routes with common paths. (That is, if two machines share a common route up to a certain place, point that out.)

3. Using anonymous ftp, retrieve the file :

   	ftp.cc.gatech.edu:/pub/linux/games/sokoban-src.tar.gz      
   

   Show the route packets took to get from that machine to yours.

   Unbundle the package and list the contents of the package. Change to the 'sokoban' directory and type 'make'. Record the results.

4. Name three responsibilities of an operating system.

5. Define each of the following:
   • Multiprocess operating system
   • finger
   • user shell
   • Command history
   • A client/server pair (Give an example)

6. What command(s) would you use to do the following:
   • Change your password
   • See who logged on the current machine last week
   • List all the entries in the /etc directory starting with the letter 'r'
   • Show when the user chaney logged on during the month of January
   • Lookup online information of the 'head' and 'tail' commands.

7. How would you permanently change your shell prompt to be:

   		;-)X->--<
   
   (Also known as the winking Bob Simon smiley doing jumping jacks)
   
   

8. How would you set/change your TERM environment variable? How would you make the change permanent?

9. Explain what stdin, stdout and stderr are and show how you would redirect each in a command. What is the difference between redirection and piping?

10. Explain what a 'PPP connection' is, including what someone needs in order to use it and any benefits of using it. Be as verbose as you like, this is an essay question.
