2 Install LibreOffice or OpenOffice into WindowsIndexup to index

When you have your Windows base system Installed (in your Desktop Operating Systems course), go to URL http://cstech/ on campus (NOT the open Internet, because it would be too slow) and download OpenOffice or LibreOffice for Windows and install it on your base Windows system, so that Windows can read and print the Open Office lab documents used in this course. To find the software on CSTECH, click any room in the left side-bar and look under Drivers and Downloads.

4.2.1 Doing work for other students makes them failIndexup to index

  • When you do the work for another student, your mark goes up (because you practice the commands) and their mark goes down (because they did nothing and can’t remember anything on the tests and exams). Make sure you are not helping another student to fail the course!

4.2.2 Your in-class notes go here - take notes in class!Indexup to index

  • Put your Name and contact information on your laptop.
  • Put your Name and contact information on your power cable.
  • Put your Name and contact information on your external drive.
  • Put your Name and contact information on everything.
  • Never use the userids abcd0001 or abcd1234. These are example userids used in the notes that are meant to be replaced with your own userid. If you try repeatedly to log in to the Course Linux Server from home using these non-existent userids, your home IP address will be locked out for a day or two.
  • Incorrect login userid abcd0001 used into the Course Linux Server causes IP lock-out:
Failed password for invalid user abcd0001 from port 36326 ssh2
refused connect from modemcable003.184-58-74.mc.videotron.ca (
  • Example advanced sysadmin command pipelines for “Find students with more than five logins and pretty-print with a nice header”:

  | grep -v -e 'idallen' -e 'cst8207a' -e 'reboot' -e 'ubuntu' -e 'wtmp' -e '^  *[1-5] ' \
  | pr -2 -f -h "more than 5 logins"
$ last | awk '$1 ~ /^[a-z][a-z][a-z0-9][a-z0-9][0-9][0-9][0-9][0-9]$/ {print $1}' \
  | sort | uniq -c | sort -n | grep -v -e '^  *[1-5] ' | pr -2 -f -h "more than 5 logins"
