3.1 The Source DirectoryIndex

All references to the “Source Directory” below are to the CLS directory ~idallen/cst8207/13f/assignment07/ and that name starts with a tilde character ~ followed by a userid with no intervening slash. The leading tilde indicates to the shell that the pathname starts with the HOME directory of the account idallen (seven letters).

4.1 Set Up on the CLSIndex

1. Create the following directory structure in your CLS HOME directory and record (for study purposes) the series of Unix commands you used to create it. Spelling and capitalization must be exactly as shown:

   CST8207-13F
   `-- Assignments
       `-- assignment07

   This directory is the base directory for most CLS pathnames in this assignment. Store your CLS files and answers here.

4.2 Part A – CentOS Installation and ConfigurationIndex

1. Complete your CentOS Virtual Machine Installation.
   • Run the Fetch and Checking Program to check your work.
2. Complete your CentOS VMware Tools Installation.
   • Run the Fetch and Checking Program to check your work.
3. Check your work using the Checking Program and submit.

4.3 When you are doneIndex

That is all the tasks you need to do.

Check your work a final time using the Checking Program and save the output as described below. Submit your mark following the directions below.

5.1 Part I - Fetch and CheckIndex

Do all the following steps on your CentOS Virtual Machine. Read through the whole list before you start typing anything. An example of what to type is given below the descriptions that follow.

1. Log in to CentOS using your root account.
2. Create a directory in the root account HOME named CST8207-13F/Assignments/assignment07 (exactly the same directory hierarchy as you already have on the CLS).
3. Change to the above assignment07 directory.

4. As shown below, use curl to get a copy of the Fetch program from the given URL into a file named do.sh. Make sure you have a file named do.sh in your assignment07 directory. You only need to download this once per assignment.

5. As shown below, use sh to run the do.sh script you just downloaded to CentOS with the USER environment variable set to your own Blackboard/CLS account userid (do not use abcd0001).

6. This Fetch program will connect from CentOS to the CLS using your account name. It will copy files from CentOS to your assignment07 directory on the CLS. It will then run the checking program on the CLS to check your work. You will need to answer one question about your IP address, and then wait and type in your CLS password.

It will look something like this (use your userid, not abcd0001):

CentOS# whoami
root
CentOS# hostname
abcd0001
CentOS$ pwd
/root/CST8207-13F/Assignments/assignment07
CentOS# curl -A mozilla http://teaching.idallen.com/cst8207/13f/notes/data/assignment07do.sh >do.sh
[... various download statistics print here ...]
CentOS# USER=abcd0001 sh do.sh
---------------------------------------------------------------------------
abcd0001: FETCH version 2.  Connecting to CLS as USER='abcd0001' using ssh

abcd0001: Use local Algonquin IP cst8207-alg.idallen.ca [y/N]? n
abcd0001: Please wait; using ssh to connect to user 'abcd0001' on cst8207.idallen.ca ...
*** COURSE LINUX SERVER ***
abcd0001@cst8207.idallen.ca's password:         # enter your CLS password
---------------------------------------------------------------------------
idallen-ubuntu assignment07fetch_server.sh version 4 run by abcd0001.
Please wait; collecting info from abcd0001 Virtual Machine

VM files collected into CST8207-13F/Assignments/assignment07/abcd0001.tar.bz on CLS.
Now running checking program for abcd0001 on CLS:
[... checking program output appears here ...]

5.2 Part II - Check and SubmitIndex

When you are done with your assignment, you need to run the checking program one last time on the CLS and submit the output file, as follows:

Do all this on the Course Linux Server:

1. There is a Checking Program named assignment07check in the Source Directory on the CLS. Create a Symbolic Link to this program named check under your new assignment07 directory on the CLS so that you can easily run the program to check your work and assign your work a mark on the CLS. Note: You can create a symbolic link to this executable program but you do not have permission to read or copy the program file.

2. Execute the above “check” program on the CLS using its symbolic link. (Review the Search Path notes if you forget how to run a program by pathname from the command line.) This program will check your fetched CentOS work, assign you a mark, and display the output on your screen. (You may want to paginate the long output so you can read all of it.)

   Remember: The checking program does not fetch new files to the CLS from your CentOS VM. You must run the Fetch program on your CentOS VM to update the fetched files on the CLS so that the checking program can mark them on the CLS.

   You may run the “check” program as many times as you wish, to correct mistakes and get the best mark. Some tasks sections require you to finish the whole section before running the checking program at the end; you may not always be able to run the checking program successfully after every single task step.

3. When you are done with checking this assignment, and you like what you see on your screen, redirect the output of the Checking Program into the text file assignment07.txt under your assignment07 directory on the CLS. Use the exact name assignment07.txt in your assignment07 directory. Case (upper/lower case letters) matters. Be absolutely accurate, as if your marks depended on it. Do not edit the file. Make sure the file actually contains the output of the checking program!

4. Transfer the above assignment07.txt file from the CLS to your local computer and verify that the file still contains all the output from the checking program. Do not edit this file! No empty files, please! Edited or damaged files will not be marked. You may want to refer to your File Transfer notes.

5. Submit the assignment07.txt file under the correct Assignment area on Blackboard (with the exact name) before the due date. Upload the file via the assignment07 “Upload Assignment” facility in Blackboard: click on the underlined assignment07 link in Blackboard. Use “Attach File” and “Submit” to upload your plain text file.

   No word-processor documents. Do not send email. Use only “Attach File”. Do not enter any text into the Submission or Comments boxes on Blackboard; I do not read them. Use only the “Attach File” section followed by the Submit button. (If you want to send me comments about your assignment, use email.)

6. Your instructor may also mark the assignment07 directory in your CLS account after the due date. Leave everything there on the CLS. Do not delete any assignment work from the CLS until after the term is over!

Use the exact file name given above. Upload only one single file of plain text, not HTML, not MSWord. No fonts, no word-processing. Plain text only.

Did I mention that the format is plain text (suitable for VIM/Nano/Pico/Gedit or Notepad)?

NO EMAIL, WORD PROCESSOR, PDF, RTF, or HTML DOCUMENTS ACCEPTED.

No marks are awarded for submitting under the wrong assignment number or for using the wrong file name. Use the exact name given above.

WARNING: Some inattentive students don’t read all these words. Don’t make that mistake! Be exact.

READ ALL THE WORDS. OH PLEASE, PLEASE, PLEASE READ ALL THE WORDS!
