Getting Started

1. About Ubuntu
Thank you for your interest in Ubuntu 6.06 LTS - the Dapper Drake release. Ubuntu is an entirely open source operating system built around the Linux kernel. The Ubuntu community is built around the ideals enshrined in the Ubuntu Philosophy [http://www.ubuntu.com/ubuntu/philosophy]: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit. For those reasons: • Ubuntu will always be free of charge, and there is no extra fee for the "enterprise edition," we make our very best work available to everyone on the same Free terms. • Ubuntu includes the very best in translations and accessibility infrastructure that the free software community has to offer, to make Ubuntu usable for as many people as possible. • Ubuntu is released regularly and predictably; a new release is made every six months. You can use the current stable release or the current development release. Each release is supported for at least 18 months. • Ubuntu is entirely committed to the principles of open source software development; we encourage people to use open source software, improve it and pass it on. The Ubuntu community is comprised of developers, programmers, testers, techwriters, documentation testers, translators, and most importantly, the people who use Ubuntu every day. We invite you to join this community and help make Ubuntu the operating system you, your family, your friends, and your colleagues will love to use. Help us translate Ubuntu into your language, try it on new and unusual hardware, improve the experience of other users with hints, tips, and FAQs, or help to shape the direction Ubuntu is headed by providing feedback about the software you love most. Find out more at the Ubuntu website [http://www.ubuntu.com].

1.1. About the Name
Ubuntu is a South African ethical ideology focusing on people's allegiances and relations with each other. The word comes from the Zulu and Xhosa languages. Ubuntu (pronounced "oo-BOON-too") is seen as a traditional African concept, is regarded as one of the founding principles of the new republic of South Africa and is connected to the idea of an African Renaissance. A rough translation of the principle of Ubuntu is "humanity towards others". Another translation could be: "the belief in a universal bond of sharing that connects all humanity". "A person with ubuntu is open and available to others, affirming of others, does not feel threatened that others are able and good, for he or she has a 10

Getting Started proper self-assurance that comes from knowing that he or she belongs in a greater whole and is diminished when others are humiliated or diminished, when others are tortured or oppressed." —Archbishop Desmond Tutu As a platform based on GNU/Linux, the Ubuntu operating system brings the spirit of ubuntu to the software world.

1.2. Free Software
The Ubuntu project is entirely committed to the principles of open source software development; people are encouraged to use open source software, improve it, and pass it on. This means that Ubuntu is and will always be free of charge. However, this means more than just being available at zero cost. The philosophy of free software is that people should be free to use software in all the ways that are "socially useful". "Free software" doesn't just mean that you shouldn't have to pay for it, it also means that you should be able to use the software in any way you wish: the code that makes up free software is available for anyone to download, change, fix, and use in any way. So apart from the fact that free software is often available without charge, this freedom also has technical advantages: when programs are developed, the hard work of others can be used and built upon. With non-free software, this cannot happen and when programs are developed, they have to start from scratch. For this reason the development of free software is fast, efficient and exciting! You can find out more about the philosophy of free software here [http://www.gnu.org/philosophy/].

1.3. The Difference
There are many different operating systems based on GNU/Linux: Debian, SuSE, Gentoo, RedHat, and Mandriva are examples. Ubuntu is yet another contender in what is already a highly competitive world. So what makes Ubuntu different? Based on Debian, one of the most widely acclaimed, technologically advanced, and well-supported distributions, Ubuntu aims to create a distribution that provides an up-to-date and coherent Linux system for desktop and server computing. Ubuntu includes a number of carefully selected packages from the Debian distribution and retains its powerful package management system which allows easy installation and clean removal of programs. Unlike most distributions that ship with a large amount of software that may or may not be of use, Ubuntu's list of packages is reduced to a number of important applications of high quality. By focusing on quality, Ubuntu produces a robust and feature-rich computing environment that is suitable for use in both home and commercial environments. The project takes the 11

Getting Started time required to focus on finer details and is able to release a version featuring the latest and greatest of today's software once every 6 months. Ubuntu is available in flavours for the i386 (386/486/Pentium(II/III/IV) and Athlon/Duron/Sempron processors), AMD64 (Athlon64, Opteron, and new 64-bit Intel processors), and PowerPC (iBook/Powerbook, G4 and G5) architectures.

1.4. Long-Term Support
Every Ubuntu release is supported for at least 18 months with security and other updates. Ubuntu 6.06 LTS is a special enterprise-ready release, and is supported for 3 years on the desktop, and 5 years on the server. The development process of Ubuntu 6.06 LTS was slightly longer than usual to concentrate on a number of areas: • Quality Assurance • Localisation • Certification As a result, it will be possible to rely on Ubuntu 6.06 LTS for a longer period than usual. Therefore this release of Ubuntu is referred to as "LTS" or "Long-Term Support".

1.5. The Desktop
The default desktop environment for Ubuntu is GNOME [http://www.gnome.org/], a leading UNIX and Linux desktop suite and development platform. Another leading UNIX and Linux desktop is KDE [http://www.kde.org/]. The Kubuntu [http://www.kubuntu.org] project offers Ubuntu users an alternative choice to the default GNOME desktop environment. Thanks to the efforts of the Kubuntu team, Ubuntu users are now able to install and use the KDE desktop easily on their system. To get a working install of Kubuntu on an Ubuntu install, install the kubuntu-desktop package. Once kubuntu-desktop is installed, one can choose to use either a Gnome or KDE desktop environment.

1.6. Version and Release Numbers
The Ubuntu version numbering scheme is based on the date we release a version of the distribution. The version number comes from the year and month of the release rather than reflecting the actual version of the software. Our first release (Warty Warthog) was in October 2004 so its version was 4.10. This version (Dapper Drake) was released in June 2006 so its version number is 6.06 LTS.

1.7. Backing and Support
Ubuntu is maintained by a quickly growing community. The project is sponsored by Canonical Ltd. [http://www.canonical.com], a holding company founded by Mark 12

Getting Started Shuttleworth. Canonical employs the core Ubuntu developers and offers support and consulting services for Ubuntu. Canonical Ltd also sponsors a number of other Open Source software projects, about which more information can be found on the Canonical website [http://www.canonical.com].

1.8. What is Linux?
The Linux kernel [http://www.kernel.org], pronounced 'lee-nucks' is the heart of the Ubuntu operating system. A kernel is an important part of any operating system, providing the communication bridge between hardware and software. Linux was brought to life in 1991 by a Finnish student named Linus Torvalds. At the time, it would run only on i386 systems, and was essentially an independently created clone of the UNIX kernel, intended to take advantage of the then-new i386 architecture. Nowadays, thanks to a substantial amount of development effort by people all around the world, Linux runs on virtually every modern architecture. The Linux kernel has gained an ideological importance as well as a technical one. There is an entire community of people who believe in the ideals of free software and spend their time helping to make open source technology as good as it can be. People in this community gave rise to initiatives such as Ubuntu, standards committees that shape the development of the Internet, organizations like the Mozilla Foundation, responsible for creating Mozilla Firefox, and countless other software projects from which you've certainly benefited in the past. The spirit of open source, commonly attributed to Linux, is influencing software developers and users everywhere to drive communities with common goals.

1.9. What is GNU?
The GNU Project, pronounced “guh-noo”, was launched in 1984 to develop a complete UNIX style operating system which is comprised of free software: the GNU system. Variants of the GNU operating system, which use the Linux kernel, are now widely used; though these systems are often referred to as “Linux,” they are more accurately called GNU/Linux systems. The GNU project is closely linked to the philosophy of free software, which is central to the projects that derive from it, such as Ubuntu. The concept of free software is explained at Section 1.2, “Free Software” [p. 11 ] .

2. Getting Ubuntu
There are a number of methods you may use to obtain a copy of Ubuntu, all of which are described on the Ubuntu Web site download page [http://www.ubuntu.com/download]. The first method is to download an ISO image from a mirror server near you and make a CD to install Ubuntu. Two types of CDs are available: • Desktop CD - the desktop CD allows you to try Ubuntu without changing your computer at all, and at your option to install it permanently later. This type of CD is what most people will want to use. • Text-mode install CD - the text-mode install CD allows you to perform certain specialist installations of Ubuntu. This type of CD is intended for cases such as creating pre-configured OEM systems or setting up automated deployments; it can also be used as a package source for upgrading older installations. If you don't have a CD burner or you have limited or expensive bandwidth, we can send you pressed copies of the 'Desktop CD' free of charge. You may request CDs via Shipit [http://shipit.ubuntu.com], the Ubuntu CD Distribution System. Ordered CDs may take several weeks to arrive.

You can also contact an Ubuntu Local Community Team (LoCoTeam) near you. These are self-organized groups of Ubuntu enthusiasts who want to bring the Ubuntu community onto a local level. Most LoCoTeams have extra copies of Ubuntu and give them out freely. A list of existing Ubuntu LoCoTeams can be found on the Ubuntu wiki [https://wiki.ubuntu.com/LoCoTeamList]. Another method of obtaining Ubuntu is to join a local Linux Users Group (LUG) and ask if somebody can make you a copy. Normally, you will have to pay for the cost of the CD and delivery. If you do not know of an LUG near you, a list can be found at Linux Users Groups WorldWide [http://lugww.counter.li.org/].

Getting Started

3. Linux Basics
Linux is inspired by the Unix operating system which first appeared in 1969, and has been in continous use and development ever since. Many of the design conventions behind Unix also exist in Linux and are central to understanding the basics of the system. Unix was primarily oriented towards the command line interface, and that legacy is carried on in Linux. Thus, the graphical user interface with its windows, icons and menus are built on top of a basic command line interface. Furthermore, this means that the Linux file system is structured to be easily manageable and accessible from the command line.

3.1. Directories and File Systems
Linux and Unix file systems are organised in a hierarchical, tree-like structure. The highest level of the file system is the / or root directory. In the Unix and Linux design philosophy, everything is considered a file - including hard disks, partitions and removable media. This means that all other files and directories (including other disks and partitions) exist under the root directory. For example, /home/jebediah/cheeses.odt shows the correct full path to the cheeses.odt file that exists in the jebediah directory which is under the home directory, which in turn, is under the root (/) directory. Underneath the root (/) directory, there is a set of important system directories that are common across most Linux distributions that are used. The following is a listing of common directories that are directly under the root (/) directory: • /bin - important binary applications • /boot - boot configuration files • /dev - the device files • /etc - configuration files, startup scripts, etc... • /home - local users' home directories • /lib - system libraries • /lost+found - provides a lost+found system for files that exist under the root (/) directory • /media - mounted (loaded) removable media such as CDs, digital cameras, etc... • /mnt - mounted filesystems • /opt - provides a location for optional applications to be installed • /proc - special dynamic directory that maintains information about the state of the system, including currently running processes • /root - root user home directory, pronounced 'slash-root' 15

Getting Started • /sbin - important system binaries • /sys - system files • /tmp - temporary files • /usr - applications and files that are mostly available for all users to access • /var - variable files such as logs and databases

3.2. Permissions
All of the files on a Linux system have permissions that allow or prevent others from viewing, modifying or executing. The super user "root" has the ability to access any file on the system. Each file has access restrictions, user restrictions and have an owner/group association. Every file is secured by the following three sets of permissions, in order of importance: • user applies to the user who is the owner of the file • group applies to the group that is associated with the file • other applies to all other users Inside each of the three sets of permissions are the actual permissons. The permissions, along with the way they apply differently to files and directories, are outlined below: • read files can be displayed/opened directory contents can be displayed • write files can be edited or deleted directory contents can be modified • execute executable files can be run as a program directories can be entered To view and edit the permissions on files and directories, open the Places → Home Folder and right-click on a file or directory. Then select Properties. The permissions exist under 16

Getting Started the Permissions tab and allow for the editing of all permission levels, if you are the owner of the file. To learn more about file permissions in Linux, read the file permissions page [https://wiki.ubuntu.com/FilePermissions] in the Ubuntu Wiki.

3.3. Root And Sudo
The root user in GNU/Linux is the user which has administrative access to your system. Normal users do not have this access for security reasons. However, Ubuntu does not include the root user. Instead, administrative access is given to individual users, who may use the "sudo" application to perform administrative tasks. The first user account you created on your system during installation will, by default, have access to sudo. You can restrict and enable sudo access to users with the Users and Groups application (see Section 3.6, “Users and Groups” [p. 19 ] for more information). When you run an application that requires root privileges, sudo will ask you to input your normal user password. This ensures that rogue applications cannot damage your system, and serves as a reminder that you are about to perform administrative actions which require you to be careful! To use sudo when using the command line, simply type "sudo" before the command you wish to run. Sudo will then prompt you for your password. Sudo will remember your password for a set amount of time. This feature was designed to allow users to perform multiple administrative tasks without being asked for a password each time. Be careful when doing administrative tasks, you might damage your system!

Some other tips on using sudo: • To use a "root" terminal, type "sudo -i" at the command line. • All of the default graphical configuration tools in Ubuntu already use sudo, so they will prompt you for your password if needed. • For more information on the sudo program and the absence of a root user in Ubuntu, read the sudo page [https://wiki.ubuntu.com/RootSudo] on the Ubuntu wiki.

3.4. Terminals
Working at the command line is not as daunting a task as you would think. There is no special knowledge needed to know how to use the command line, it is a program like everything else. Most things in Linux can be done using the command line, although there 17

Getting Started are graphical tools for most programs, sometimes they are just not enough. This is where the command line comes in handy. The terminal is often called the command prompt or the shell. In days gone by, this was the way the user interacted with the computer, however Linux users have found that the use of the shell can be quicker than a graphical method and still holds some merit today. Here you will learn how to use the terminal. The original use of the terminal was a file browser and indeed it is still used as a file browser, in the event of the graphical environment failing. You can use the terminal as a file browser to navigate your files and undo the changes that have been made. 3.4.1. Starting the Terminal To start Terminal choose Applications → Accessories → Terminal . 3.4.2. Common Commands View Directories: - ls The ls (LiSt) lists files in different colors with full formatted text Create Directories: - mkdir (directory name) The mkdir (MaKeDIRectory) command will create a directory. Change Directories: - cd (/directory/location) The cd (ChangeDirectory) command will change from your current directory to any directory you specify. Copy Files/Directories: - cp (file or directory name) (to directory or filename) The cp (CoPy) command will copy any files you specify. The cp -r command will copy any directories you specify. Remove Files/Directories: - rm (file or directory name) The rm (ReMove) command will delete any filename you specify. The rm -rf command will remove any directory you specify. Rename Files/Directories: - mv (file or directory name) The mv (MoVe) command will rename/move any file or directory you specify. Find Files/Directories: - locate (file or directory name) The locate command will search your computer for any filename you specify. It uses an index of the files on your system to work quickly: to update this index run the command updatedb. This command is run automatically each day, if you leave your computer on. It needs to be run with administrative privileges (see Section 3.3, “Root And Sudo” [p. 17 ] ). You can also use wildcards to match one or more files, such as "*" (for all files) or "?" (to match one character). For a more thorough introduction to the Linux command line, please read the command line introduction [https://wiki.ubuntu.com/BasicCommands] on the Ubuntu wiki. 18

Getting Started 3.4.3. Switch to Console mode The usual method of command-line access in Ubuntu is to start a terminal (see Section 3.4.1, “Starting the Terminal” [p. 18 ] above) , however sometimes it is useful to switch to the real console: 1. 2. Use the Ctrl-Alt-F1 shortcut keys to switch to the first console. To switch back to Desktop mode, use the Ctrl-Alt-F7 shortcut keys. There are six consoles available. Each one is accessible with the shortcut keys Ctrl-Alt-F1 to Ctrl-Alt-F6. 3.4.4. Disable the beep sound in Terminal mode 1. Start a Terminal session, select: Applications → Accessories → Terminal from the desktop menu system. 2. Edit → Current Profile... . Select the General tab. Uncheck the Terminal bell checkbox.

3.5. Text Editing
All of the configurations and settings in Linux are saved in text files. Even though you most often can edit configurations through the graphical interface, you may occasionally have to edit them by hand. Gedit is the default Ubuntu text editor, which you can launch by clicking Applications → Accessories → Text Editor on the desktop menu system. At times in this guide, Gedit is run from the command line using gksudo, which runs Gedit with administrative privileges, in order to modify configuration files. If you need to use a text editor from the command line, you can use nano, which is a simple to use text editor. When running it from the command line, always use the following command, which ensures that the editor will not introduce line breaks:
nano -w

For more information about how to use nano, refer to the guide on the wiki [https://wiki.ubuntu.com/NanoHowto]. There are also quite a few other terminal-based editors available in Ubuntu, popular ones include VIM and Emacs (the pros and cons of each are cause for much friendly debate within the Linux community). These are often more complex to use than nano, but are also more powerful.

3.6. Users and Groups
To add users or groups to your system, you can use the Users And Groups application located in System → Administration → Users and Groups . 19

Getting Started To add a new user, click on Add user, fill-in the data fields then click OK. To edit the properties of each user, click the Properties button located in the main Users window. To add a new group, select the Groups tab and click Add group. Choose a name for the new group and, if you want, change the default value for the Group ID. If you try to allocate a Group ID that is in use, the system will warn you. You can add users to the newly created group by selecting a user from the left menu and clicking on the Add button. Removing a user is as simple as adding one: select a user from the right menu then click Remove. When you are ready, click OK and the new group with its users, if inserted, will be created. To edit the properties of a group, from within the Groups main window, choose a group name and click on the Properties button. To remove a user or a group from the system, select the user or group you want to delete and click Delete.

Chapter 2. Adding, Removing and Updating Applications
This chapter is a complete guide to adding, removing and updating applications on an Ubuntu system.

21

Adding, Removing and Updating Applications

1. Introduction
In order to add or remove applications in Ubuntu you need to use a package manager. A package manager is a tool that makes installing and uninstalling applications easy by handling the software in preconfigured packages that are optimized for Ubuntu. The following package managers are described in this chapter: • Add/Remove Applications - this is the simplest way to manage programs. • Synaptic - this graphical program provides a more advanced means of managing programs. • APT - this is a powerful command line program to manage programs. You may also wish to increase the number of programs available to install through your package managers. Not all the programs that exist for Ubuntu are available by default. You may have to add extra repositories in order to make them available: that is also described in this chapter. Finally, this chapter explains how to update your system. You can only have one package management application running at a time. For example, if you are running Add/Remove Applications and try to launch Update Ubuntu, it will fail with an error. Close the running application before you relaunch the new one.

22

Adding, Removing and Updating Applications

2. Add/Remove Applications
Add/Remove Applications is a simple graphical way of installing and removing applications in Ubuntu. To launch Add/Remove Applications click Applications → Add/Remove Applications on the desktop menu system. Running Add/Remove Applications requires administrative privileges (see Section 3.3, “Root And Sudo” [p. 17]). To install new applications select the category on the left, then check the box of the application you want to install. When finished click Apply, then your chosen programs will be downloaded and installed automatically, as well as installing any additional applications that are required. Alternatively, if you know the name of the program you want, use the Search tool at the top. If you have not activated the online package archive, you may be asked to insert your Ubuntu CD-ROM to install some packages. Some applications and packages are not available to install using Add/Remove Applications. If you cannot find the package you are looking for, click Advanced which will open the Synaptic package manager (see below).

23

Adding, Removing and Updating Applications

3. Synaptic Package Manager
Synaptic is an advanced package management application that can install and remove every package available to your system. The interface is graphical like Add/Remove Applications but a lot more information is presented to the user, which means that Synaptic gives you complete control over the package management of your system. Running Synaptic requires administrative privileges (see Section 3.3, “Root And Sudo” [p. 17]). To launch Synaptic, choose System → Administration → Synaptic Package Manager on the desktop menu system. The Synaptic screen is divided up into four sections, the two most important being the package categories on the left side, and the packages on the right. To install packages, just choose the category, find the package name in the list, right click on it and choose "Mark this package for installation". Once you are satisfied with your selections click Apply on the top button bar. Synaptic will then download and install the required packages from the online repositories and/or from your Ubuntu installation CD. Alternatively you can click the Search tool bar button, enter the package name or a short search term in the search text field and click the Search button. Synaptic will now show you a much shorter list from which to select your application for installation. This is usually much easier than having to look through the very long list of applications on your own.

24

Adding, Removing and Updating Applications

4. Command Line Package Management
4.1. APT
APT (Advanced Packaging Tool) is a powerful package management system, on which the graphical programs described above like Add/Remove Applications and Synaptic are based. APT automatically handles dependencies and performs other operations on system packages to allow the installation of the desired package/s. Running APT requires administrative privileges (see Section 3.3, “Root And Sudo” [p. 17]). Some common commands that can be used with APT: • Install packages:
sudo apt-get install packagename

• Remove packages:
sudo apt-get remove packagename

• Retrieve new lists of packages:
sudo apt-get update

• Upgrade system with available updates:
sudo apt-get upgrade

• List further commands and options:
apt-get help

For further information about the use of APT, read the comprehensive Debian APT User Manual [http://www.debian.org/doc/user-manuals#apt-howto].

Adding, Removing and Updating Applications

5. Installing a Single Package File
The preferred method of installing programs is via the package managers described in this chapter. However, although the Ubuntu package archives are very large, it is possible that you may wish to install a package which is not available in the Ubuntu archives. If this happens, you can also download and install files from websites. It is important to ensure that any files you download come from a safe source before installing them. There are many different kinds of Linux package files. Most of these are associated with the package managers of specific Linux distributions. Examples are Debian Package files (.deb files), Redhat Package Manager files (.rpm files), and Tarballs (.tar files). This section deals with installing these single files. It is not guaranteed that these files will be compatible with your system and you will not receive security updates if you install these files. For these reasons, if you wish to install a program, always use a native Ubuntu package of the application available through a package manager, if there is one available.

5.1. Install/uninstall .deb files
These files are Debian packages. The package files associated with Ubuntu have the .deb suffix because of Ubuntu's close relations with the Debian GNU/Linux distribution. You will need administrative privileges to install a .deb file (see Section 3.3, “Root And Sudo” [p. 17]). 1. 2. To install a .deb file, simply double click on it, and then select Install Package Alternatively, you can also install a .deb file by opening a terminal and typing:
sudo dpkg -i package_file.deb

3.

To uninstall a .deb file, deselect it in your package manager, or type:
sudo dpkg -r package_name

5.2. Convert .rpm files to .deb files
Another type of package files is Red Hat Package Manager files which have the .rpm suffix. It is not recommended to install these on an Ubuntu system. In almost all cases, a native Ubuntu .deb package is available. However, if absolutely necessary, an .rpm file can be converted to a .deb package using the program alien. 1. 2. Install the alien program (Chapter 2, Adding, Removing and Updating Applications [p. 21]). Run the following command in a terminal, with administrative privileges: 26

Adding, Removing and Updating Applications
sudo alien package_file.rpm

5.3. Install tarballs
Files with the .tar.gz or .tar.bz2 suffix are package files known as tarballs which are widely used in Linux and Unix. If there is no native Ubuntu package available in any of the Ubuntu repositories, you can use the command line to install or uninstall the Tarball file by following the instructions that come with the package. Tarballs often contain the source code of the program, and need to be compiled in order to be used. To do this, extra software will generally be needed (see Section 8.1, “Basic Compilers” [p. 48 ] ).

Adding, Removing and Updating Applications

6. Extra Repositories
6.1. What are Repositories?
There are thousands of programs available to install on Ubuntu. These programs are stored in software archives (repositories) and are made freely available for installation over the Internet. This makes it very easy to install new programs in Linux, and it is also very secure, because each program you install is built specially for Ubuntu and checked before it is installed. To organise the software, Ubuntu repositories are categorised into four groups: Main, Restricted, Universe, and Multiverse. The rationale used to determine which software goes into which category is based on two factors: • The level of support software development teams provide for a program. • The level of compliance the program has to the Free Software Philosophy [http://www.ubuntu.com/ubuntu/philosophy]. You can find more information about the Repositories available on the website [http://www.ubuntu.com/ubuntu/components]. The standard Ubuntu Install CD contains some software from the Main and Restricted categories. Once your system is made aware of the Internet-based locations for these repositories, many more software programs are made available for installation. Using the software package management tools already installed on your system, you can search for, install and update any piece of software directly over the Internet, without the need for the CD.

6.2. Adding Extra Repositories
To enable the extra repositories: 1. 2. 3. Open System → Administration → Software Properties . Select Add To enable the Universe repository, check the Community Maintained (Universe) button. Adding this repository will mean that the majority of the Free Software universe will be available to install on your system. This software is supported by a carefully selected group of volunteers within the Ubuntu Community, but is not supported by the core Ubuntu development team and may not include security updates. 4. To enable the Multiverse repository, check the Non-free (Multiverse) button. 28

Adding, Removing and Updating Applications Adding this repository will mean that software which has been classified as non-free will be available to install on your system. This software may not be permitted in some jurisdictions. When installing each package from this repository, you should verify that the laws of your country permit you to use it. Again, this software may not include security updates. 5. 6. Click Close to save your changes and exit. To apply your changes, select Reload.

29

Adding, Removing and Updating Applications

7. Updates
Sometimes the Ubuntu developers release feature and security updates for applications and packages within the Ubuntu system. When these updates are available, Ubuntu will inform you with a pop-up and a red icon in your notification area. To update your system, click the red button, enter your password and click OK. The Update Manager program will list the available updates: to download and install these updates click Install Updates. Ubuntu will then download and install the available updates from the Internet. When Update Manager has finished updating your system, close the pop-up window with the Close button, then close Update Manager to finish updating your system. After installing some important updates, it may be necessary to restart your computer. If so, Ubuntu will inform you with a popup and an icon in your notification area.

Common Tasks

1. Music
1.1. Playing and Extracting Audio CDs
When you insert an audio CD, the Sound Juicer CD player and ripper opens automatically. To play the CD, click the Play button or press Ctrl-P. To play a particular track, double-click on the track or select the track and click Play. To extract (rip) your audio CD, make sure the tracks that you want to rip are selected, then click the Extract button or press Ctrl-Enter. If you are connected to the internet, Sound Juicer will retrieve the CD artist, title, and track data from MusicBrainz.org [http://musicbrainz.org], a community-maintained database which contains data on over 360,000 albums. To start Sound Juicer manually, choose Applications → Sound & Video → Sound Juicer CD Extractor. You can use the preferences window to control where the extracted audio files are stored on your computer, the filename of extracted audio files, and the file format and codec used for the files. In the main window, choose Edit → Preferences. Sound Juicer can extract audio files to the following formats: • Ogg Vorbis - Ogg Vorbis is a patent-free lossy audio compression format which typically produces higher quality and greater compression than MP3. See the Vorbis website [http://www.vorbis.com/faq/] for more information. • FLAC - FLAC is the Free Lossless Audio Codec. It can compress audio files up to 50% without removing any information from the audio stream. For more information on this format, see the FLAC homepage [http://flac.sourceforge.net/] on sourceforge.net. • WAV - Use the WAV format for voice recordings. Sound Juicer uses this format for low quality mono audio files. You can also extract CD audio files to the proprietary non-free MP3 format. Instructions on how to rip to the MP3 format are in the help for Sound Juicer. Choose Help → Contents and navigate to the Preferences section.

1.2. Burning CDs
When you put a blank CD in the drive Ubuntu will ask if you want to burn an audio or data CD. Clicking on Burn Audio CD will launch Serpentine . To add music to your audio CD, either drag music from your File Browser or use the Add button. You will also need to select the size of your CD (21, 74, 80 or 90 minutes). Serpentine will warn you if you exceed the set limit. 32

Common Tasks To make a photo or data CD, click the burn Burn Data CD. Ubuntu will open a CD/DVD Creator window. The CD Creator is built into the File Browser, and it allows you to add any file or folder you have permission to access. When you are ready to burn the CD, click Write to Disc. Ubuntu will then prompt you to select the drive containing the blank CD, and give you the opportunity to name the CD and select the write speed. Finally, click Write to create the new photo or data CD.

1.3. Playing and Organising Music Files
To play and organize your music, Ubuntu comes with#Rhythmbox Music Player, which looks similar to iTunes. When you first start Rhythmbox, it will scan your home directory for any supported music files you have and add it to the database. To start Rhythmbox, choose Applications → Sound & Video → Rhythmbox Music Player Ubuntu does not directly support the MP3 format, because it is restricted by patents and proprietary rights. Instead Ubuntu supports the Ogg Vorbis format out of the box, a completely free, open and non-patented format. Ogg Vorbis files also sound better then MP3 files of the same file size and are supported by many popular music players (a list of players is here [http://wiki.xiph.org/index.php/PortablePlayers]). You can still play your old MP3 files by installing MP3 support (see Section 3, “Multimedia Codecs” [p. 38 ] ). Instructions for other formats, such as Windows Media Audio (wma/wmv) and other patent encumbered formats can be found on the Ubuntu Wiki [http://wiki.ubuntu.com/RestrictedFormats]. The Cowbell ID3 tag editor can edit the metadata on your mp3 and other music files. To use Cowbell: 1. Install the cowbell package from the Universe repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]); To run Cowbell, choose Applications → Sound & Video → Cowbell Music Organizer.

Common Tasks

2. Video
To play video, Ubuntu comes with Totem Movie Player which looks and functions similar to Windows Media Player. Some features of Totem include custom playlists, DVD playback and more. You can start Totem by clicking: Applications → Sound & Video → Movie Player from the desktop menu system. To read video files, Totem uses the Gstreamer framework. To play some video formats, you may need to add further codec support (see Section 3, “Multimedia Codecs” [p. 38 ] ). There are also other multimedia applications available. Examples include Mplayer, Xine and Totem-xine (which uses the Xine framework, instead of the Gstreamer framework. Some users may benefit from trying alternative video players.

2.1. DVD Playback
The movie players provided in Ubuntu are capable of reading DVDs that are not encrypted. However, most commercial DVDs are encrypted with CSS (the Content Scrambling System) and currently for legal reasons it is not possible to include support for these DVDs in Ubuntu. However it is possible to enable support as follows: The legal status of this library is not fully clear. In some countries it is possible that the use of this library to play or copy DVDs is not permitted by law. Verify that you are within your rights in using it. 1. Install the libdvdread3 package (see Chapter 2, Adding, Removing and Updating Applications [p. 21]). You will need to use Synaptic Package Manager to install this package

2.

To activate DVD decryption, type the following line into a terminal prompt:
sudo /usr/share/doc/libdvdread3/examples/install-css.sh

3.

To play DVDs with Totem, you will need to install some extra codecs (see Section 3, “Multimedia Codecs” [p. 38 ] ). However, the Gstreamer framework (used by Totem) does not support menus or subtitles for DVD playback. For this reason, you can install a separate DVD player, Xine, which supports these. To install Xine, install the gxine package from the Universe repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]). You can then open gxine from the Sound & Video menu. 35

37

Common Tasks

3. Multimedia Codecs
Many applications in Ubuntu use the GStreamer open source multimedia framework. The codec plugins for GStreamer are organised in different packages depending on the licensing that applies to the various codecs. You can see which codecs are contained in which plugin on the GStreamer website [http://gstreamer.freedesktop.org/documentation/plugins.html]. Other applications, such as Mplayer and Xine, do not use the Gstreamer framework. Due to patent and copyright restrictions, codecs for these programs are not included at all in Ubuntu. For more information on these read the Restricted Formats [https://wiki.ubuntu.com/RestrictedFormats] wiki page.

3.1. Add Codecs to Gstreamer
To install extra codecs for Gstreamer: • Install the following packages from the Universe and Multiverse repositories (see Chapter 2, Adding, Removing and Updating Applications [p. 21]): gstreamer0.10-plugins-ugly gstreamer0.10-plugins-ugly-multiverse gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse gstreamer0.10-ffmpeg

Configuring Your System

1. Desktop Tricks
This section details some tips for using and customising Ubuntu's desktop environment (called GNOME), and the file manager (called Nautilus).

1.1. Menu Editing
Ubuntu comes with the Alacarte Menu Editor, so you can customize your menus and add entries for applications that don't automatically appear after they are installed. To add a new menu entry: 1. Open Alacarte with Applications → Accessories → Alacarte Menu Editor, or by right-clicking on any top-level menu and choosing Edit Menus. 2. 3. In Alacarte's left-hand pane, choose the submenu the new entry should appear in. Choose File → New Entry. In the New Entry window, choose a Name, Comment, Command and Icon. The Command will usually be the package name, Name is what will appear on the menu, and the Comment will appear in the tooltip that appears near the menu entry. Icons are added to the /usr/share/pixmaps directory by default, or can be chosen from anywhere in your files. To change the order of menu entries, use the up and down arrows on the right-hand side of the Alacarte window. To stop a menu entry from being displayed, use the checkboxes beside each entry. This does not erase the menu entry, so you can restore it later in the same way.

1.2. Start a Program Manually
Sometimes it can be useful to start a program manually, for example when the program does not have an entry in the menu. This is easy to do with the Run Applications dialogue. For an application you intend to use regularly that does not have a menu entry, it is also very easy to add a menu entry to Ubuntu. (see Section 1.1, “Menu Editing” [p. 51 ] ) 1. 2. Open the Run Applications dialogue by typing:# Alt-F2 Enter the name of the program you wish to run, and press Enter.

1.3. Run programs automatically when GNOME starts
1. 2. 3. Choose System → Preferences → Sessions . Click on the Startup Programs tab. Use the Add, Edit, and Delete buttons to manage programs to run at startup. Some programs will automatically add themselves to this list when you configure them. 51

Configuring Your System

1.4. Login automatically to GNOME when the computer starts
It is possible to login a user automatically when the computer boots. This is not recommended for most computers, as it is not secure and may allow other users access to your information 1. 2. 3. System → Administration → Login Screen Setup Select the Security tab. Check the Enable Automatic Login checkbox option. Choose the user you wish to be automatically logged in.

1.5. Change Display Mode in Nautilus
Ubuntu's file manager Nautilus provides two modes in which you can interact with your filesystem: Spatial mode and Browser mode. • In Browser mode, the file manager window represents a browser, which can display any location. Opening a folder updates the current file manager window to show the contents of the new folder. • In Spatial mode, the file manager window represents a particular folder. Opening a folder opens the new window for that folder. Each time you open a particular folder, you will find its window displayed in the same place on the screen and the same size as the last time you viewed it (this the reason for the name). Browser mode is the default setting on Ubuntu, but you may wish to change this: 1. 2. 3. 4. In Nautilus, choose Edit → Preferences. Click on the Behavior tab. Unselect the Always open in browser windows check box. Close and reopen Nautilus.

1.6. Show hidden files and folders in Nautilus
1. In Nautilus, use the Ctrl-H shortcut keys to toggle hidden files and folders on and off, or select View → Show Hidden Files. 2. 3. 4. To permanently show all hidden files and folders, choose Edit → Preferences. Click on the Views tab. Select the Show hidden and backup files check box.

1.7. Open the Location Bar in Nautilus
The Location Bar is the bar in your file manager in which you can type an address. Toggle the bar on and off with: Go → Location... You can also use the Ctrl-L shortcut keys. 52

Configuring Your System

1.8. View remote SSH, FTP, and SFTP servers using Nautilus
1. 2. Make sure the Nautilus Location Bar is open (see Section 1.7, “Open the Location Bar in Nautilus” [p. 52 ] ). In the Location Bar, enter the following: For SSH, use:
ssh://username@ssh.server.com

For FTP, use:
ftp://username@ftp.server.com

For SFTP, use:
sftp://username@sftp.server.com

Replace username with your username and replace everything after the @ symbol with the server's address. You will be prompted for a password if needed. If there is no username (anonymous) omit the username and the @ symbol. Alternatively, to specify your password manually, change one of the above like so:
ftp://username:password@ftp.server.com

3.

To access remote servers easily through Nautilus, add a permanent bookmark to the server by selecting Places → Connect to Server... and entering the details for the remote server.

1.9. Change the default "Open with" program for a file type
1. 2. 3. In Nautilus, right click on the file and choose Properties from the menu that appears. The Properties dialog opens. Click on the Open With tab. A list of applications appears. Select the default application you want for the file type. If the application is not on the list, use the Add button to add the application to the list.

1.10. Open files with administrative privileges from the file manager
To enable support for opening files with administrative privileges from the file manager, you need to add a Nautilus script: Please note that opening files with administrative privileges constitutes a security risk. Always ensure that you are familiar with the file that you are opening. 1. Open a new file to edit in the relevant directory:
gedit $HOME/.gnome2/nautilus-scripts/Open\ as\ Administrator

2.

Insert the following lines into the new file:

53

Configuring Your System
for uri in $NAUTILUS_SCRIPT_SELECTED_URIS; do gksudo "gnome-open $uri" & done

3. 4.

Save the edited file (an example [../sample/nautilus_open_as_administrator]) Make the edited file executable:
chmod +x $HOME/.gnome2/nautilus-scripts/Open\ as\ Administrator

5.

You can now open files as root by right clicking on the file and selecting Scripts → Open as Administrator

1.11. Install Extra Fonts
This section describes how to install extra fonts from the Ubuntu archives. 1. For international fonts, install the following packages from the Universe repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]): xfonts-intl-arabic xfonts-intl-asian xfonts-intl-chinese xfonts-intl-chinese-big xfonts-intl-european xfonts-intl-japanese xfonts-intl-japanese-big xfonts-intl-phonetic 2. For Microsoft TrueType core fonts, install the msttcorefonts package from the Multiverse repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]). For Ghostscript fonts, install the gsfonts-x11 package (see Chapter 2, Adding, Removing and Updating Applications [p. 21]). After installing any new font, rebuild the font information files by typing the following at a terminal prompt:
sudo fc-cache -f -v

3. 4.

If you prefer to download individual fonts by hand, you can install them simply and easily by opening a file manager, and typing fonts:/// into the location bar (See Section 1.7, “Open the Location Bar in Nautilus” [p. 52 ] ). Then you can simply drag the font you downloaded into the group of existing fonts.

1.12. RAR Archiver
1. Install the rar package from the Multiverse repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]).

54

Configuring Your System 2. Run:

sudo ln -fs /usr/bin/rar /usr/bin/unrar

3.

To open a rar file, double click on it.

1.13. Advanced Desktop Applets
gDesklets is a system for bringing mini programs (desklets), such as weather forecasts, news tickers, system information displays, or music player controls, onto your desktop, in a symbiotic relationship of eye candy and usefulness. 1. 2. 3. Install the gdesklets and gdesklets-data packages from the Universe repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]). Choose: Applications → Accessories → gDesklets For more information, visit the gDesklets website [http://www.gdesklets.org/]

1.14. Hide Recent Documents in the Places menu
To hide Recent Documents from the Places menu, open a terminal and run the command:
chmod 400 ~/.recently-used

To enable it again, run the command:
chmod 600 ~/.recently-used

1.15. Show the Computer, Home, and Trash desktop icons in GNOME
1. 2. 3. Open the Configuration Editor, by running the program gconf-editor (see Section 1.2, “Start a Program Manually” [p. 51 ] ). Choose apps → nautilus → desktop. Tick the box beside computer_icon_visible, home_icon_visible, and trash_icon_visible. The changes take effect immediately.

1.16. Change my preferred email client to Mozilla Thunderbird
1. 2. 3. Choose System → Preferences → Preferred Applications Click on the Mail Reader tab, and select the Custom option. In the Command text box, type mozilla-thunderbird %s, then close the dialog.

1.17. Restart GNOME without rebooting the computer
1. 2. 3. Save and close all open applications. Use the Ctrl-Alt-Backspace shortcut keys to restart GNOME. If Ctrl-Alt-Backspace is disabled, type 55

Configuring Your System
sudo /etc/init.d/gdm restart

(See Section 1.18, “Preventing the Ctrl-Alt-Backspace shortcut keys from restarting X” [p. 56 ] to disable Ctrl-Alt-Backspace.)

1.18. Preventing the Ctrl-Alt-Backspace shortcut keys from restarting X
1. Make a backup copy of your existing /etc/X11/xorg.conf file:
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup

2.

Open /etc/X11/xorg.conf for editing:
gksudo gedit /etc/X11/xorg.conf

3.

Add the following lines to the end of the file:
Section "ServerFlags" Option "DontZap" "yes" EndSection

4. 5.

Save the edited file (an example [../sample/xorg.conf_disablectrlaltbackspacegnome]). The change will take effect the next time you log in to GNOME. If you want the change to take effect immediately, restart GNOME manually. (See Section 1.17, “Restart GNOME without rebooting the computer” [p. 55 ] .)

Configuring Your System

2. Partitions and Booting
2.1. Graphical Partition Editor
Gparted is a graphical tool to edit disk partitions. 1. 2. Install the gparted package (see Chapter 2, Adding, Removing and Updating Applications [p. 21]). You can run the application with System → Administration → Gnome Partition Editor .

2.2. Make partitions available from Ubuntu
Windows and other partitions should be automatically available from any Ubuntu system. If they are not, you can enable them using the graphical disks tool. 1. 2. 3. 4. Open System → Administration → Disks Select the correct hard disk, and click the Partitions tab. Select the relevant partition, and click Enable. To unmount the partition, click Disable.

2.3. Make partitions automatically available
Again, Windows and other partitions should be automatically available from Ubuntu. If they are not, the following procedure will make them automatically available: 1. 2. Read Section 3.7.1, “Check disk space usage and view the partition table” [p. 63 ] First make a directory where the partition can be made available ("mounted"):

sudo mkdir /media/windows

3.

Next, backup your disk configuration file and open the file in a text editor with administrative privileges:

sudo cp /etc/fstab /etc/fstab_backup gksudo gedit /etc/fstab

4.

Append the following line at the end of file:
/dev/hda1 /media/windows ntfs umask=0222 0 0

Replace /dev/hda1 with the correct device name for your partition. If your Windows partition uses the FAT32 filesystem, replace ntfs with vfat in the above command. 57

Configuring Your System If you have a FAT32 filesystem, it is also safe to allow read-write access. To do this, change the value of umask to 0000. 5. 6. Save the edited file (an example [../sample/fstab_automountntfs]) The changes will take effect when the computer is restarted.

2.4. Run a system command automatically at startup
Sometimes it can be useful to add a custom command to the startup process so that your computer executes it on every boot. To do this: 1. Edit the crontab with administrative privileges (see Section 3.3, “Root And Sudo” [p. 17]):
sudo crontab -e

2.

Insert the following line:
@reboot /home/user/command

Replace /home/user/command with the full address to your command. 3. Save the file and exit.

2.5. Change default Operating System at boot
To change the Operating System which starts by default when booting, it is necessary to edit the configuration file for booting. 1. Make a backup of your boot configuration file, and open it in a text editor:
sudo cp /boot/grub/menu.lst /boot/grub/menu.lst_backup gksudo gedit /boot/grub/menu.lst

2.

Find this line:
... default 0 ...

3.

Replace with the following line:
default X_sequence

4.

Save the edited file (an example [../sample/menu.list_changedefaultosgrub])

2.6. Permanently disable/enable boot-up services
This requires administrative privileges (see Section 3.3, “Root And Sudo” [p. 17]). 1. 2. Run Services Settings: System → Administration → Services. Enter your password.

58

Configuring Your System 3. 4. Tick/untick the services you want running, then click OK when done. For greater control over the boot-up services, install the bum from the Universe repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]) and run it: System → Administration → Boot-up Manager.

59

Configuring Your System

3. Hardware
3.1. Digital Cameras
Most USB digital cameras will be automatically detected by Ubuntu. Simply plug in and switch on your USB digital camera, Ubuntu will then ask you if you would like to import the photos from your camera. Click on Import, Ubuntu will then show you a preview of your photos. Choose a location to save your photos to, then click on Import, Ubuntu will then save your photos to your hard drive. If you do not get the auto-import popup with your camera, it might be worth starting gThumb and trying File → Import Photos.... See Section 6.1, “gThumb Image Viewer” [p. 45] for more on gThumb.

3.2. 3D Graphic Cards
3.2.1. Introduction to 3D Video Acceleration Most video hardware should work automatically with Ubuntu. However with some types of video hardware, 3D acceleration (which is needed by some games) will not be supported automatically. This section details how to get this working with some popular video hardware. The first step is to find out whether 3D acceleration is working. 1. To do this, enter in a terminal:
glxinfo | grep rendering

2.

If 3D acceleration is working, the following will be displayed:
direct rendering: Yes

3.

If not, follow the instructions in the following sections to activate 3D acceleration.

3.2.2. 3D Nvidia Video Card Driver No Nvidia Video cards have 3D acceleration enabled automatically with Ubuntu, because the manufacturer does not release open source drivers. However, it is possible to activate 3D acceleration. The process depends on which type of video card you have. 1. If you have an older TNT, TNT2, TNT Ultra, GeForce1 or GeForce2 card, install the nvidia-glx-legacy and nvidia-settings packages from the Restricted repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]). Alternatively, if you have a newer card, install the nvidia-glx package from the Restricted repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]). To enable the new driver, run the following command in a terminal: 60

2.

3.

Configuring Your System

sudo nvidia-glx-config enable

4.

You may adjust the settings of the new drivers by running the application nvidia-settings (see Section 1.2, “Start a Program Manually” [p. 51]). If you wish, add a menu entry for this program (see Section 1.1, “Menu Editing” [p. 51]).

3.2.3. 3D ATI Video Card Driver Many ATI video cards work well with Ubuntu automatically. To check that 3d acceleration works with your card, see Section 3.2.1, “Introduction to 3D Video Acceleration” [p. 60 ] . If it does not work, this procedure should activate it. 1. 2. Install the xorg-driver-fglrx package from the Restricted repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]). You now need to configure the computer to use the new driver so run this command in a terminal:

sudo dpkg-reconfigure xserver-xorg

3. 4. 5. 6.

When the dialogue appears and asks whether to do automatic detection of your video, pick Yes. When asked to select a driver, pick fglrx. Follow the remaining instructions as appropriate. Restart your machine for changes to take effect.

3.3. Keyboard Layouts
This section deals with adding keyboard layouts to your system, and switching between them easily. 3.3.1. Add a Layout To add a keyboard layout to your system: 1. 2. 3. 4. Go to System → Preferences → Keyboard Choose Layouts Press Add... to add further keyboard layouts. It is simpler to have two layouts; the maximum is currently four. Close the dialogue.

3.3.2. Switch Keyboard Layouts To switch between keyboard layouts, you can set a key combination: 1. 2. Go to System → Preferences → Keyboard To configure your layouts, choose Layout Options

61

Configuring Your System 3. 4. Expand the Group Shift/Lock behaviour option Choose the key combination that enables you to switch between keyboard layouts. The default is by pressing both Alt keys at the same time. A common alternative is to use Alt-Shift. 5. 6. Close the dialogue You can now use your key combination to switch between keyboard layouts.

3.3.3. Keyboard Indicator Alternatively add the Keyboard Indicator applet to your panel: 1. 2. 3. 4. Right-click on an empty space on the panel where you want to add the applet Click Add to Panel... Choose Keyboard Indicator from the Utilities section You can now right-click on the Keyboard Indicator to manage your keyboard layouts.

3.4. Wireless Cards
Many wireless cards are automatically detected by Ubuntu during installation. A complete listing of wireless cards which work with Ubuntu can be found on Ubuntu Wiki [https://wiki.ubuntu.com/HardwareSupportComponentsWirelessNetworkCards]. Please add your wireless card to the list if it works with Ubuntu. Some cards may not work automatically with Ubuntu. If this is the case, please look at the Wireless Troubleshooting Guide [https://wiki.ubuntu.com/WirelessTroubleshootingGuide] on the Ubuntu Wiki which is an excellent resource for troubleshooting wireless cards. All information regarding wireless networking on Ubuntu is collected at Wireless Networking Central [https://wiki.ubuntu.com/WifiDocs] on the Ubuntu Wiki.

3.5. Modems
3.5.1. Winmodems Most winmodems are not supported by Ubuntu, but drivers can be found that will enable the use of such modems. First you need to identify what chipset your winmodem is using:

wget -c http://linmodems.technion.ac.il/packages/scanModem.gz gunzip -c scanModem.gz > scanModem chmod +x scanModem sudo ./scanModem gedit Modem/ModemData.txt

Read this file, it should list what modem chipset you have. Once you are aware of the chipset you have, see http://www.linmodems.org/ and follow the 62

Configuring Your System directions for your modem. More infomation can be found at SettingUpModems [https://wiki.ubuntu.com/SettingUpModems] on the Ubuntu Wiki. 3.5.2. ADSL Modems All PPPOE and router-style ADSL modems are supported by Ubuntu (that use ethernet for the connections), and some USB ADSL modems are supported too. For router-style ADSL modems, just connect it up, configure the modem as per your ISPs instructions and configure networking in Ubuntu. For information on PPPOE modems see this guide [https://wiki.ubuntu.com/ADSLPPPoE] on the Ubuntu wiki.

3.6. Printers
Some printers will be automatically detected by Ubuntu; for those that are not, choose System → Administration → Printing then choose Printer → Add Printer and run the Printer Install Wizard. There are some printers that need further setup. Search the databases at LinuxPrinting.org [http://www.linuxprinting.org/] or check the Ubuntu Wiki's Printer page [https://wiki.ubuntu.com/HardwareSupportComponentsPrinters] for possible information on your printer.

3.7. Other Tips
3.7.1. Check disk space usage and view the partition table 1. 2. 3. Launch System → Administration → Disks Select the Harddrive, then the Partitions tab Each partition will be listed under Partition List, with disk space and mount point.

3.7.2. List devices 1. To list mounted devices, run the following command in a terminal:
mount

The listing shows the device (such as a hard disk partition), the mount point (where you access the files), the filesystem type and the mount options. This example shows the hda2 hard disk partition mounted as '/', with the filesystem type ext3. The partition is mounted with two options, one to allow the device to be read from and wrote to and the other to remount the device as read only in the event of any errors.
/dev/hda2 on / type ext3 (rw,errors=remount-ro)

2.

To list PCI devices:

4. Networking
4.1. Change the Computer Name
1. 2. 3. System → Administration → Networking Select the General tab. Enter the name of the computer in the Hostname field. Click OK, close all open applications and reboot.

4.2. Networking Utilities
4.2.1. Firestarter Firewall A firewall protects a computer system from unauthorized access. It is not normally necessary to install a firewall on an Ubuntu system, because access to the system is closed by default. However, if you run any services which you allow other computers to access (for example, the Apache web server), it is advisable to install a firewall. Firestarter is a program which allows you to control a firewall through a graphical interface. 1. 2. Install the Firestarter package from the Universe repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]). After it is installed, run Applications → System Tools → Firestarter to configure your firewall. The firewall will now start in the background when your computer starts. 4.2.2. Graphical Network Monitor Etherape displays network activity among different hosts using circles of varying size. 1. 2. Install the etherape package from the Universe repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]). Choose: Applications → Internet → Etherape

4.2.3. Network Traffic Analyzer Ethereal is a network traffic analyzer/sniffer that captures packets off the network in real time and displays the contents of them. 1. 2. Install the ethereal package from the Universe repository (see Chapter 2, Adding, Removing and Updating Applications [p. 21]). Choose: Applications → Internet → Ethereal

The above rights include the right to make such modifications as are technically necessary to exercise the rights in other media and formats. All rights not expressly granted by Licensor are hereby reserved. 4. Restrictions. The license granted in Section 3 above is expressly made subject to and limited by the following restrictions: a. You may distribute, publicly display, publicly perform, or publicly digitally perform the Work only under the terms of this License, and You must include a copy of, or the Uniform Resource Identifier for, this License with every copy or phonorecord of the Work You distribute, publicly display, publicly perform, or publicly digitally perform. You may not offer or impose any terms on the Work that alter or restrict the terms of this License or the recipients' exercise of the rights granted hereunder. You may not sublicense the Work. You must keep intact all notices that refer to this License and to the disclaimer of warranties. You may not distribute, publicly display, publicly perform, or publicly digitally perform the Work with any technological measures that control access or use of the Work in a manner inconsistent with the terms of this License Agreement. The above applies to the Work as incorporated in a Collective Work, but this does not require the Collective Work apart from the Work itself to be made subject to the terms of this License. If You create a Collective Work, upon notice from any Licensor You must, to the extent practicable, remove from the Collective Work any reference to such Licensor or the Original Author, as requested. If You create a Derivative Work, upon notice from any Licensor You must, to the extent practicable, remove from the Derivative Work any reference to such Licensor or the Original Author, as requested. b. You may distribute, publicly display, publicly perform, or publicly digitally perform a Derivative Work only under the terms of this License, a later version of this License with the same License Elements as this License, or a Creative Commons iCommons license that contains the same License Elements as this License (e.g. Attribution-ShareAlike 2.0 Japan). You must include a copy of, or the Uniform Resource Identifier for, this License or other license specified in the previous sentence with every copy or phonorecord of each Derivative Work You distribute, publicly display, publicly perform, or publicly digitally perform. You may not offer or impose any terms on the Derivative Works that alter or restrict the terms of this License or the recipients' exercise of the rights granted hereunder, and You must keep intact all notices that refer to this License and to the disclaimer of warranties. You may not distribute, publicly display, publicly perform, or publicly digitally perform the Derivative Work with any technological measures that control access or use of the Work in a manner inconsistent with the terms of this License Agreement. The above applies to the Derivative Work as incorporated in a Collective Work, but 69

Creative Commons by Attribution-ShareAlike 2.0 this does not require the Collective Work apart from the Derivative Work itself to be made subject to the terms of this License. c. If you distribute, publicly display, publicly perform, or publicly digitally perform the Work or any Derivative Works or Collective Works, You must keep intact all copyright notices for the Work and give the Original Author credit reasonable to the medium or means You are utilizing by conveying the name (or pseudonym if applicable) of the Original Author if supplied; the title of the Work if supplied; to the extent reasonably practicable, the Uniform Resource Identifier, if any, that Licensor specifies to be associated with the Work, unless such URI does not refer to the copyright notice or licensing information for the Work; and in the case of a Derivative Work, a credit identifying the use of the Work in the Derivative Work (e.g., "French translation of the Work by Original Author," or "Screenplay based on original Work by Original Author"). Such credit may be implemented in any reasonable manner; provided, however, that in the case of a Derivative Work or Collective Work, at a minimum such credit will appear where any other comparable authorship credit appears and in a manner at least as prominent as such other comparable authorship credit. 5. Representations, Warranties and Disclaimer UNLESS OTHERWISE AGREED TO BY THE PARTIES IN WRITING, LICENSOR OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE MATERIALS, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU. 6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 7. Termination a. This License and the rights granted hereunder will terminate automatically upon any breach by You of the terms of this License. Individuals or entities who have received Derivative Works or Collective Works from You under this License, however, will not have their licenses terminated provided such individuals or entities remain in

70

Creative Commons by Attribution-ShareAlike 2.0 full compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will survive any termination of this License. b. Subject to the above terms and conditions, the license granted here is perpetual (for the duration of the applicable copyright in the Work). Notwithstanding the above, Licensor reserves the right to release the Work under different license terms or to stop distributing the Work at any time; provided, however that any such election will not serve to withdraw this License (or any other license that has been, or is required to be, granted under the terms of this License), and this License will continue in full force and effect unless terminated as stated above. 8. Miscellaneous a. Each time You distribute or publicly digitally perform the Work or a Collective Work, the Licensor offers to the recipient a license to the Work on the same terms and conditions as the license granted to You under this License. b. Each time You distribute or publicly digitally perform a Derivative Work, Licensor offers to the recipient a license to the original Work on the same terms and conditions as the license granted to You under this License. c. If any provision of this License is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this License, and without further action by the parties to this agreement, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable. d. No term or provision of this License shall be deemed waived and no breach consented to unless such waiver or consent shall be in writing and signed by the party to be charged with such waiver or consent. e. This License constitutes the entire agreement between the parties with respect to the Work licensed here. There are no understandings, agreements or representations with respect to the Work not specified here. Licensor shall not be bound by any additional provisions that may appear in any communication from You. This License may not be modified without the mutual written agreement of the Licensor and You. Creative Commons is not a party to this License, and makes no warranty whatsoever in connection with the Work. Creative Commons will not be liable to You or any party on any legal theory for any damages whatsoever, including without limitation any general, special, incidental or consequential damages arising in connection to this license. Notwithstanding the foregoing two (2) sentences, if Creative Commons has expressly identified itself as the Licensor hereunder, it shall have all rights and obligations of Licensor. Except for the limited purpose of indicating to the public that the Work is licensed under the CCPL, neither party will use the trademark "Creative Commons" or any related trademark or logo of Creative Commons without the prior written consent of Creative 71

Appendix B. GNU Free Documentation License
Version 1.2, November 2002 Copyright © 2000,2001,2002 Free Software Foundation, Inc. Free Software Foundation, Inc. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Version 1.2, November 2002 PREAMBLE The purpose of this License is to make a manual, textbook, or other functional and useful document "free" in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others. This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software. We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference. APPLICABILITY AND DEFINITIONS This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The "Document", below, refers to any such 73

GNU Free Documentation License manual or work. Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law. A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language. A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them. The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none. The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words. A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque". Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally 74

GNU Free Documentation License available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only. The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text. A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition. The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License. VERBATIM COPYING You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3. You may also lend copies, under the same conditions stated above, and you may publicly display copies. COPYING IN QUANTITY If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with 75

GNU Free Documentation License changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects. If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages. If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public. It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document. MODIFICATIONS You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:

GNU FDL Modification Conditions
A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission. B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement. C. State on the Title page the name of the publisher of the Modified Version, as the publisher. D. Preserve all the copyright notices of the Document. E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. 76

GNU Free Documentation License F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum [p. 80 ] below. G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice. H. Include an unaltered copy of this License. I. Preserve the section Entitled "History", Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled "History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the "History" section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission. K. For any section Entitled "Acknowledgements" or "Dedications", Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles. M.Delete any section Entitled "Endorsements". Such a section may not be included in the Modified Version. N. Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title with any Invariant Section. O. Preserve any Warranty Disclaimers. If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles. You may add a section Entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard. You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified 77

GNU Free Documentation License Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one. The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version. COMBINING DOCUMENTS You may combine the Document with other documents released under this License, under the terms defined in section 4 [p. 76 ] above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers. The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work. In the combination, you must combine any sections Entitled "History" in the various original documents, forming one section Entitled "History"; likewise combine any sections Entitled "Acknowledgements", and any sections Entitled "Dedications". You must delete all sections Entitled "Endorsements". COLLECTIONS OF DOCUMENTS You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects. You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document. AGGREGATION WITH INDEPENDENT WORKS A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an 78

GNU Free Documentation License "aggregate" if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document. If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate. TRANSLATION Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail. If a section in the Document is Entitled "Acknowledgements", "Dedications", or "History", the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title. TERMINATION You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this License. Any other attempt to copy, modify, sublicense or distribute the Document is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. FUTURE REVISIONS OF THIS LICENSE The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/. Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified 79

GNU Free Documentation License version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. ADDENDUM: How to use this License for your documents To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page:

Sample Invariant Sections list
Copyright (c) YEAR YOUR NAME. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.2 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled "GNU Free Documentation License". If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the "with...Texts." line with this:

Sample Invariant Sections list
with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation. If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
