Summer 2000 CS 691X UNIX System Administration

Logistics

The class meets MW 1-3:20pm, in ECS 237. The class is scheduled to run for eight weeks.

Each monitor in the lab must be powered off or set on a screen saver at the end of each class. Please turn them off for the weekend.

Textbooks

Linux Kernel Internals, Beck et al, second edition, Addison-Wesley.
Essential System Administration, AEleen Frisch, published by O'Reilly, second edition,

Objectives

To learn basics of UNIX system administration
Emphasis on problem-solving, as opposed to cookbook solutions
To demonstrate skills in setting up and operating heterogeneous networks.

Requirements

Build a UNIX site, with users, groups, shared printers, shared filesystems, etc. (35%)
Present a chapter from the Frisch or Beck book to the class. Use HTML. (20%)
Open-book quizes based on presented chapters. (10%)
Do a small kernel modification, and install it on your PC. (10%)
Conduct and present an individual or small group project. All projects will be presented to the class at the end of the term, in lieu of a final exam. Projects may involve outside reading or other research. Group projects will involve an implementation. (25%)

Course Outline

This course is scheduled to run for eight weeks, two sessions per week. So the sessions are numbered 1-16 in the list below.

The following was taken from the course page for summer 1999 and is provided to give you an idea of the course content.

May 25
- Introduction
- Overview of lab facilities
- Demo: installation of Redhat LINUX
- Students make an inventory of the PCs in the lab, noting (when possible) the memory and disk situations, and the machine's IP address.
- Reading assignment for next session: Chapters 1 and 2 of ESA textbook.
May 31
- Introduction and course overview. Begin a tour of hte UNIX filesystem.
June 5
- We installed Redhat 6.2 Linux on the machines in the ECS 237 lab. Each machine's IP address is 130.85.99.9+n, where n is the number assiged to the PC. For example, PC 13 gets the IP 130.85.99.22.
- The broadcast mask should be 255.255.255.0, and the name servers set to 130.85.1.4 and 130.85.1.5.
- The generic multisync monitor seems to work for all the machines, and the Mach 64 video card. Some machines may need different settings.
- Let's use the same root password on all machines in the lab. That password will be cs691x.
June 7
- More of the tour of the file system, and some useful commands for sysadmins.
- Some helpful pieces of information:
  - To get out of X Windows, type CTRL-ALT-BACKSPACE
  - To do a clean reboot, we recommend the command sync;sync;reboot. To stop the system, as you would before powering off, use sync;sync;halt.
  - To make the slides for your chapters, I recommend Powerpoint. You may choose to use Powerpoint with HTML as the output format. Please email to me a copy of your presentation, preferably in Powerpoint format, so that I can put it on the course web page.
- Discuss the Linix loader, known as LILO. More on Booting a Linux System
- June 3
  - Cindy Johnson presented Nemeth Chapter 3. (Powerpoint version.)
  - Harry Chen presented Nemeth Chapter 4
  - By now, we should have finished installing Linux on the Pentiums, Discuss the following questions:
    1. Where does LINUX keep its logs?
    2. Where are the rc scripts, which get run at boot time?
    3. Where are the HOWTOs?
- June 8
  - Discussion of Nemeth Chapter 5 (Julie Jiao)
  - Discussion of Nemeth Chapter 6 (Debbie Merson)
- June 10
  - Discussion of Nemeth Chapter 7 (Alhabashi Khattab)
  - Discussion of Nemeth Chapter 9 (Zhao Ying and Andrej Cedilnik)
  - Several commands in the /sbin directory, with the term 'mod' in the command name, are applicable to Linux loadable kernel modules. Examples include 'lsmod' and 'modprobe'.
  - Reading assignment: chapters 1 and 2 of Linux Kernel Internals
  - Demonstrated compilation of the Linux kernel, using 'make xconfig'. It's also possible to use 'make config' or 'make menuconfig'. In general, a brand new kernel should be put onto a floppy for initial testing. The command 'dd bs=8192 if=zImage of=/dev/fd0' can be used for this purpose, without changing the kernel on the hard disk. The command 'make zdisk' will issue the dd command for you.
- June 15
  - We need to figure out the characteristics of these monitors if we're to use 'make xconfig' effectively.
  - Demonstrate a kernel recompile.
- June 17
  - Discussion of Nemeth Chapter 10 (Zheng Yan)
  - Discussion of Nemeth Chapter 11 (Honglin Su)
  - Discussion of Nemeth Chapter 12 (Haiying Bao)
- June 22
  - Discussion of Nemeth Chapter 13 (Liang Xu and Jihong Chen)
  - Discussion of Nemeth Chapter 14 (Kejian Wu, Yiqing Ren, Xiao-min Su)
- June 24
  - Discussion of Beck Chapter 3 (Grant Braught)
  - Discussion of Beck Chapter 4 (Scott Jiang)
- June 29
  - Discussion of Nemeth Chapter 16. Yun Wan's part and Shanshan Liu's part.
  - Discussion of Beck Chapter 6 (Ying Ouyang)

The following XF86Config file seems to work well for the machines in the lab ECS 237. This file should be placed in the directory /etc/X11.
