Assignments

Publish homework where ever you want. You can use your myy homepage or http://tero.sulautetut.fi. Once you’ve published your homework, put a link into Moodle answer box. If you are afraid or otherwise reluctant to publish your work, you can also return the whole thing into Moodle. Publishing will be good advertising for you!

Use normal html for publishing web pages. Each student does homework separately and writes his own report. You can of course advice fellow students if they get stuck. Homeworks must be on the homepage one whole day before next class. Mention my course: “Based on Linux Basics course by Tero Karvinen http://www.iki.fi/karvinen“. If you want, you can use a Free license (like the license of Linux) by adding text: “Copyright 2007 YOUR NAME. GNU General Public License, version 2 or later. “.

Homeworks are official only after announced in the class. But feel free to have a look what I’m initially planning.

Install

h-1: a) Burn Ubuntu Desktop on a CD-ROM. b) Install Ubuntu on your movable hard drive. c) Try live CD on another computer (not lab computer)

Desktop

2a) Install three applications using package manager. Describe their functionality. Include screenshots. Try to pick software that’s interesting or usefull to you.

2b) Install language support for your language (If you are a native English speaker, pick another language). System: Administration: Language Support adds languages. Login screen bottom left corner Options let’s you choose language. How well does it work? Characters displaying correctly? Spellcheck working? Translations correct?

2c) List applications you are using on your old operating system (Windows, OSX, Linux). Notice the purpose of each piece of software. Find a Free alternative to each application. This writing task doesn’t require working on a computer.

2d) Bonus (not mandatory): Read Free Software Foundation’s Free Software Definition. Give an example of using each freedom. Make it clear who is using it, doing what, with which software and what is the benefit. This writing task doesn’t require working on a computer.

2e) Bonus (not mandatory): What are the most popular Free licenses (meeting the FSF definition for Free software)? This writing task doesn’t require working on a computer.

2f) Bonus (not mandatory): help translate a program https://translations.launchpad.net/

Command Line

h-3: a) Try all the commands learned, many times – learn them all by heart. For this a part, only document if something unexpected happens or if you want more information about some command. Do and report: b) Try 5 commands (other than those mentioned on the class or the Command Line document). Use ‘man -k foo’ to find new commands if needed c) write a story of a day with command line. Invent relevant tasks. Use commands learned and others.

Administration

h-4: a) Install three new pieces of software we have not tried before. Use command line interface for this. b) Give a short example of their use. c) Analyze a log of your choosing. Concentrate on some specific aspect or service. You can choose any log from /var/log/ you want, but most common are syslog, dmesg, Xorg.0.log and apache/*. You can use ‘grep’ to pick interesting lines. d) Optional hard: Install and use PGP enigmail Commands for Admin

b) Pick 5 lines from Apache logs and analyze them. Try to choose different kinds of lines. Extract as much information as possible.

Optional c) install and test mysql-server and phpmyadmin, see my Bilkent notes.
