Winter 2019 - January to April 2019 - Updated 2022-05-04 04:39 EDT
The Course Linux Server will be archived and shut down permanently at noon on April 30 2019 because the CLS system administrator (Ian!) had to resign from the College and nobody else knows how to maintain a Linux server for a class of 120 students.
For options on continuing to use Linux, see below.

Reminder: There are now three quizzes that you need to complete (five times each) on Brightspace as part of your term Quiz mark. The third quiz has be posted. The Quizzes are not optional; see the Course Outline. You need to do each quiz at least five times.
Check the due date for each assignment and put a reminder in your agenda, calendar, and digital assistant. Just like in the Real World, not all due dates are on the same days or at the same times.
This course had two midterm tests (10%, 15%) and will have one final exam (40%).
Follow this link to see all your upcoming Quizzes, Tests, Final Exam. The dates are also posted on the Course Home Page and on Brightspace CST8207.
For full marks, read the Test Instructions web page (all the words) before your tests.
There is no group work in this course.
Because of the large number of students who shared, copied, and worked together on scripts in previous terms and who were all charged with Academic Dishonesty during Exam Week, you must now declare that you are the sole author of your scripts. You must write all your own scripts.
You must type the text from the Academic Honesty Declaration into the end (bottom) of every script you write in this course. See Assignment #12 HTML for the details.
If any of your scripts is found to have text in common with any other people, you will be charged with Academic Dishonesty (AA18) or Plagiarism (AA20) in the middle of your Exam Week, and your course marks may be delayed and downgraded. An Academic Discipline hearing is highly disruptive to your Exam Week. Do your own assignments; do not share, work together, or copy from another student or from the Internet.
Students who give answers (e.g. command lines) to other students are helping those other students fail my course. Stop doing that. I want everyone to pass my course. Let people do their own thinking.
Take notes in class! Keep a pad open on your desk.
Look at the Practice Tests and Answers related to the Final Exam. You can bring your questions to your lab periods and your instructor will go over them with you.
Check your EMail, especially when creating CRON jobs. One student had generated over 2,600 email messages (one per minute) using a CRON job that failed. (I deleted the job.)
Don’t forget to finish your five Brightspace quiz attempts for each of the Midterm 1 and Midterm 2 quizzes. There is a third quiz available to prepare for the Final Exam. Do at least five attempts in all three quizzes.
Nobody should have any files larger than 1MB in their CLS account.
If you have uploaded an image that is larger than 1MB, you should
make it smaller using the convert
command directions given in
the Student Web Site page from
Assignment #09.
“The Bash Academy is an initiative to promote the bash shell language and educate people on its use.” http://www.bash.academy/
Regarding world-writable files in your account: See last week’s notes.
Keep a notebook with a List of Commands in it.
All commands have now been covered in the course.
Sorry, all the personal student web pages were only available on the Course Linux Server that had to be shut down in June 2019.
I do not recommend installing Linux as a “dual boot” option. Installing in a Virtual Machine (VM) is a better option, because:
Here are some student options for continuing to use Linux/Unix:
You can get a free BSD Unix shell account here: https://sdf.org/
You can wait and install your own Linux virtual machine in CST8177.
These CST8177 instructions below are obsolete, because the linux2.ca
domain has expired. You may find some old notes in the Internet
Archive, e.g. http://web.archive.org/web/*/http://www.linux2.ca
CST8177 used to install Linux in a VM, but they overwrote the old notes when the prof created the new term and the links may be broken:
To install Linux in a VM now, you can use an old version of CST8177 notes here: LINK BROKEN http://www.linux2.ca/
To install Linux in a VM now, you can use a very old version of CST8207 CentOS Installation notes
In our last class we wrote the script attack_whois.sh.txt and then I touched it up, made the output pretty, and added some comments. The output of the script now looks like this (April 2019):

above is because Korea publishes its whois
information in Korean, and the English field Country:
is not used.
I did my final Linux Rap at the start of class on Tuesday, April 16, 2019.
“Only do, what only you can do.” - E.W.Dijkstra(?), John Maxwell(?), John Harvey Jones(?), others(?)…
With this quote and my upcoming necessary resignation from Algonquin College firmly in mind, I solicited four words from the students at the start of my last 8am Linux lecture class, wrote them on the board, put on a rainbow hoodie and orange pants, and performed a short freestyle, completely improvised rap that included all of the words they gave me.
