Welcome to OPS235 - Introduction to Open System Servers

What This Course is About

This course is the second in a series of courses about Linux technologies:

• ULI101 taught you to be a Linux user. In OPS235, you will move from being Linux a user to being a Linux system administrator.

• As a system administrator, you will be responsible for installing, configuring, adjusting, maintaining, and troubleshooting the operation of computer systems. This is a lot of responsibility, and with that responsibility comes power. You will be able to change anything on the system, and you will also have the ability to damage or destroy the system.

• In this course you use a removable disk tray with the lab computers to set up a Linux system. You will also set up at least four additional Linux systems using "Virtual Machines", and therefore gain experience with different types of system configurations as well as setting up networking between systems.

• Later courses (OPS335 and OPS435) teach you to administer Linux servers (web servers, DNS servers, FTP servers, file sharing servers) -- and to use more complex scripting to boost your system administration efficiency.

Learning by Doing

Most of the learning in this course occurs through the hands-on problem solving that takes place in the eight labs and two assignments.

Requirements for Success:

• It is very important to stay up-to-date with the coursework, and to practice until you have confidently mastered each task.

• All of the software used in this course is open source software, so you are free to use, modify, and redistribute it. This means that you can install it as many times as you want on as many different computers as you would like. It also means that you can tinker with it -- you can take it apart, see how it works, and put it back together in the same or a different way, limited only by your time and ambition. You are encouraged to experiment and question liberally.

• The notes that you make during the labs and assignments are your reference material for the quizzes, tests, and assignments. Take really good notes, and if you have questions, experiment and consult with your professor.

• Carefully read ALL lab instructions and check your work regularly. The labs have been designed with backup safeguards to prevent the student from losing their work. On the other hand, students may lose their work if they fail to follow lab instructions or accidentally forget their removable hard disks in the workstation's hard disk bay drive!

Additional Hardware

Item	Item Details	Graphic
SATA Hard Disk in Removable Drive Tray	Hard Disk Size: at least 250GB. Please buy the tray from the bookstore as not all trays are compatible. Mechanical shock from dropping a hard drive causes drive failure for several students each semester. If you use a mechanical hard drive, be careful not to drop it, and transport it in a padded container (e.g. wrapped in an old shirt). SSDs are becoming competitive in price, are faster, and are less susceptible to shock, so you may want to look for a deal on an SSD instead of a hard drive -- but check to ensure that your SSD will fit properly into your drive tray. Please tighten the drive screws securely to prevent the tray from jamming in the holder, or leave the screws off.	Hard Disk in Disk Tray At least 250 GB (available at the Bookstore)
USB Flash Drive	Doesn't matter what size. You can use this key for other things as well. This is not 100% required but can be very useful when troubleshooting.	A single USB key

Study Aids

Item	Item Details	Graphic
Lab Log-Book	Download and Print: Lab log book (PDF). Please note that you can use your log book during quizzes, written tests, practical tests and the final exam. It's also the record that you have completed the labs, so don't lose it!	Lab Log-Book Used for marking labs and as an evaluation aid

Important Information

Bring all of these supplies to each class. Even after installation, the Live CD and Installation DVD may be required. Place your Full Name and Contact Information on the hard disk tray cover and directly on the disk drive. Use an adhesive label and permanent marker, or a white marker on the black cover. No label - no marks for your labs. Always "double-check" that you have removable your hard disk tray prior to exiting the lab room. You may have your hard drive tray stolen which will result in lost work! Do not share your OPS235 disk drive with another course. The work you do in other courses may damage the Linux parts on your drive. Earlier labs become the foundation for later labs. Seemingly "small errors", or "skipping instructions" in earlier labs can have negative consequences when performing other dependent labs. Make backups when requested at the end of labs for "restoration points" in case something goes wrong while performing a lab. Always shut down your system under software control, rather than using the reset or power buttons. You can shutdown using the GUI or with the poweroff, reboot, init, or shutdown commands. Shut down your virtual machines before shutting down your main system.

Failure to listen to lab "suggestions" by this resource could result in loss of work...
