344 Part III . Choosing and Installing a Linux Distribution . Programming tools A good set of tools for developing software across a variety of programming environments. KNOPPIX is based on Debian Linux, so a Debian user will be particularly comfortable with the selection and organization of features. KNOPPIX software packages are also done in deb package format, so you can use apt, dpkg, and related tools to list and otherwise manage the packages. A graphical tool for working with software packages that comes with KNOPPIX is KPackage. Refer to Chapter 9 for information on using apt and dpkg tools for managing software in Debian. Even if you don t install any new software, those tools provide an excellent way to search, list, or even upgrade software packages that are running in KNOPPIX. What s Cool About KNOPPIX The features just described are ones that come with many different Linux distributions. What makes them special with KNOPPIX is that you can often be up and using those features within a few minutes without having to repartition your disk, install software, or do any configuration. For just trying out Linux or using it for some special, quick task such as playing or displaying music, documents, or spreadsheets from a computer s hard disk, KNOPPIX is quite awesome. Some features, however, are specific to KNOPPIX (as compared to a Linux system you would run from a hard disk). Many of those special features are there to help you through issues that relate to the fact that you are not working in a permanent setup. In particular, KNOPPIX includes the following: . Extraordinary hardware detection The capability to properly detect and configure hardware is one of the best features. During the boot-up procedure, KNOPPIX finds most common PC hardware components and loads the proper modules so it can use them. Its hwsetup tool relies on the Red Hat libkudzu facility to identify hardware, load appropriate modules, and create necessary device files. For hardware that can t be detected, there are many boot options you can add to properly identify (or skip over) selected hardware devices. Some of them deal with particularly sticky issues related to video cards and running on laptop computers. (See Tables 11-1 through 11-3.) . Automatic desktop startup Instead of just dropping you to a command line, KNOPPIX does its best to start up a complete KDE desktop environment. Along the way, it adds some nice features, such as desktop icons giving you access to your computer s hard disk partitions. Note

Chapter 11 . Running KNOPPIX 343 In fact, there are so many features, I won t even try to mention them all here, but take a look at the following list of some of KNOPPIX s major components: . KDE A full-featured KDE desktop (which runs on the X Window System) that includes tools for configuring the desktop and a bunch of applications tailored for the KDE environment. (See Chapter 3 for descriptions of KDE.) If you prefer the GNOME desktop environment, there are several customized versions of KNOPPIX that include GNOME. Most notable is the Gnoppix (www .gnoppix.org) distribution, which uses GNOME as its default desktop. . OpenOffice.org The OpenOffice.org suite of office productivity tools so that you can create documents, graphics, presentations, spreadsheets, and most anything you expect to be able to do with office applications. With KNOPPIX, I can give a presentation created in OpenOffice.org software anywhere that I have access to a PC. (See Chapter 21 for descriptions of OpenOffice.org productivity applications.) . Internet tools Web browsers (Firefox, Konqueror, and Lynx), e-mail clients (Thunderbird, Kmail, Mozilla mail, and mutt), a chat client (XChat IRC), a news reader (KNode), an instant messaging client (Gaim), and many more applications for using the Internet. (See Chapter 22 for descriptions of popular Web browsers and mail clients.) . Multimedia software Applications for playing music (xmms and Juk), editing music (Audacity), watching TV (xawtv), playing movies (xine), working with graphics (GIMP and ImageMagick), using Webcams (gqcam), and displaying images (KView and Kuickshow). (Chapter 20 covers music and video players.) . Games A few dozen diverting board games, card games, strategy games, and puzzles to play. Try Potato Guy to keep the young ones busy, and Kasteroids for the older kids. (Chapter 23 talks about KDE games and other games that you can run with KNOPPIX.) . Administrative tools A nice set of system and network administration tools that enables you to do some pretty advanced setup, monitoring, and debugging of your computer and network. (The Knoppix-STD distribution is configured specifically as a rescue CD to do almost anything you can imagine to check and fix your computer and network.) . Servers A few of the powerful server projects available for Linux, many of which don t require a lot of disk space: a Web server (Apache), file server (NFS), Window file/print server (Samba), proxy server (Squid), DNS server (bind9), login server (sshd), and DHCP server (dhcpd). Using KNOPPIX (or any other bootable server Linux systems described in Chapter 19) as a server opens some amazing possibilities for serving the data from a Windows or other operating system to a network, while completely bypassing that operating system on the computer s hard disk.

342 Part III . Choosing and Installing a Linux Distribution with a special release of KNOPPIX 4.0 DVD. This release also came with the announcement that there will be two versions of KNOPPIX: one DVD, referred to as the Maxi version, and the other in the traditional CD format, referred to as the Light version, starting with the official 4.0 release in August 2005. KNOPPIX Features KNOPPIX has so many features it s hard to find a place to start. The latest official version of KNOPPIX at the time of this writing (KNOPPIX 4.0.2), features OpenOffice.org 2.0, KDE 3.4.1, GIMP 2, linux kernel 2.6.12, as well as many multimedia applications. More information can be found on the KNOPPIX homepage (http://www.knoppix.com). One of the biggest features of the most recent versions of KNOPPIX is the ease with which you can create your own, personalized KNOPPIX disk. The available options are so vast that there is not enough room to cover them in this book. For more information on how to create your own version of KNOPPIX, see http://www.knopper.net. Understanding KNOPPIX If you are impatient to get started, you don t have to read any further. In most cases, you can just insert your DVD into your PC, reboot the computer, and start using KNOPPIX. If you have the time, however, read on a bit more. KNOPPIX is a bootable Linux that includes a nice selection of open source software. Originally, there was a CD version of KNOPPIX (about 700MB image). Now, there is also a DVD version (about 3.1GB image). It is the KNOPPIX CD image that is included on the DVD that comes with this book. KNOPPIX is considered to be the best bootable Linux available. In fact, KNOPPIX is used as the basis for many specialized Linux live CDs, including Gnoppix (featuring GNOME instead of KDE), KNOPPIX STD (security), KnoppMyth (MythTV media player), and KnoppiXMAME (console game player), to name a few. To try out the latest features, however, you should start with the most recent version of KNOPPIX, as described in the rest of this chapter. Looking Inside KNOPPIX KNOPPIX boots right up to a full-featured desktop system complete with hundreds of desktop applications. It includes some powerful server and power user features.

Running KNOPPIX Acomputer s operating system usually resides on the hard disk but it doesn t have to. When a computer boots up, it typically checks first if there is a CD, floppy disk, or DVD in a drive and tries to boot from there (depending on BIOS settings). So, with up to 700MB (CD) or 4.7GB (DVD) of space on those media, why not use them to boot whole operating systems? Well, that s exactly what bootable Linux distributions (also called live CDs) such as KNOPPIX do. In the case of KNOPPIX, one CD holds up to 2GB of compressed software for you to run that uncompresses on-the-fly. Start it up and you can try out all the features of a well-stocked Linux system, without touching the contents of your hard disk. KNOPPIX is included on the DVD that comes with this book. In fact, it is the default option. Insert the DVD into your PC s DVD drive, and when you see the boot screen, press Enter. KNOPPIX should just start up, and you can begin using it as described in this chapter. If you have never used Linux before, KNOPPIX gives you the chance to do so in a very safe way. If you are experienced with Linux, KNOPPIX can be used as a tool to take Linux with you everywhere, troubleshoot a computer, or check whether a computer will run Linux. In any case, you can use this chapter to take a little tour of some great Linux features that you can try out with KNOPPIX. KNOPPIX News Each year at the German Linux symposium known as LinuxTag, Klaus Knopper, the creator of KNOPPIX, releases a special, preview version of KNOPPIX. The 2005 LinuxTag was no exception, On the DVD-ROM 1C H A1P1T E R . . . . In This Chapter Understanding KNOPPIX Starting KNOPPIX Using KNOPPIX . . . .

Chapter 10 . Running SUSE Linux 339 . Support A SUSE desktop icon takes you to a page that lets you check for software updates or get a free Novell Linux Newsletter. The Newsletter subscription page also gives you opportunities to subscribe to other Novell Linux services. . My Computer A My Computer icon on the desktop enables you to see removable media and mounted partitions, and also gives you access to your Desktop, Documents, and public_html folders in a Konqueror window. . Reconfigure your computer Get to the YaST administration tool by selecting System.Control Center (YaST) from the SUSE menu. You can reconfigure your system hardware and software from the YaST Control Center. If you want to configure your desktop (change backgrounds, screen savers, or themes), use the KDE control center as you would with any KDE desktop. You can launch the control center from the SUSE menu (select Control Center). Summary SUSE is generally considered to be the best choice for enterprise-quality Linux systems, along with Red Hat Enterprise Linux. Its graphical installation and administrative tools (implemented in a facility called YaST) set it apart from other Linux distributions geared more toward technical users. Since SUSE was acquired by Novell in 2003, SUSE Linux has become part of a larger, enterprise-ready product line. Boxed sets of SUSE Linux are available. Support offerings are available at many different levels. With Novell s worldwide sales and training organization, SUSE Linux has the backing it needs to compete to become the world s most popular commercial Linux system. Because so much work has gone into the YaST installer and administrative interface, even an inexperienced user can be up and running on a newly installed SUSE system within an hour. It s then easy to begin using a variety of desktop and personal productivity applications from the SUSE desktop. . . .

338 Part III . Choosing and Installing a Linux Distribution After you are done, click Next. SUSE sets up and lets you test your network connections. 18. User Authentication Method. Normally, you will use your home computer in standalone mode, as it relates to user accounts. However, in a business setting, you may use NIS, LDAP, or Samba to get user account lists that allow access to yours and other computers on your LAN. If the latter is the case, select Network Client and choose either NIS (a common facility used by UNIX systems to share configuration files) or LDAP (a standard directory service, used to share address books and other kinds of information on a network), depending on what your company supports. Choosing Samba lets you use Windows SMB file and print sharing features for authentication. Then click Next. 19. Add a New Local User. You will want to add at least one user account, as prompted, for your computer. Right now, you have only the root user account set up for use on a standalone machine. Using that account for e-mail, Web browsing, or other common tasks is considered bad security practice. So you should add at least one user account for non-administrative use of your computer. Add your full name, a short, one-word login name, and a password to protect that account. Then click Next. When you are done, YaST writes the system configuration information to your computer. It then displays the Release Notes for your current version of SUSE. Click Next to continue. 20. Hardware Configuration. You now have the opportunity to configure other hardware devices to use with your system. Select to configure your graphics card, printer, sound card, or TV card. After graphics configuration, you should test your display as prompted. If the settings you choose don t work, select Ctrl+Alt+Backspace to exit and try to configure it again. When you are done configuring hardware, click Accept. The settings are written to hard disk. An Installation Completed screen appears. 21. Finish. Click Finish. The system reboots and is ready for you to log in. Starting with SUSE If you created a user account during the preceding installation, SUSE should automatically log you in as that user and present you with the KDE desktop. (If you are presented with a graphical login screen instead, log in as that user now.) Here are a few things to help you get started using SUSE: . Desktop applications The default SUSE 10.0 install is configured as a desktop system that includes a set of easily accessible desktop applications. On the desktop, try the Office icon to open OpenOffice.org to work with documents, spreadsheets, presentations, drawings, Web pages, or a variety of other content types. From the SUSE icon on the panel, select from among dozens of applications to try out.

Chapter 10 . Running SUSE Linux 337 If you are sharing your hard disk with other operating systems (such as Windows or another version of Linux), consider putting your boot loader on floppy disk. In that way, you can test out the boot loader without actually changing the permanent master boot record on your hard disk. If the boot loader doesn t work, simply remove the floppy disk to reboot the original way. 13. Language. Select the default language to use. (You can add support for other languages later, if you like.) 14. Default Runlevel. Normally you d use the default (5) to boot to a full multiuser, networked desktop system with a graphical login screen. The other common default is 3, which provides a text-based login screen but is otherwise the same. (If you choose 3, you can start the GUI after login by typing the startx command.) 15. Start the install. If the Installation settings all look okay, click Accept to begin the install process. Remember that this is your last chance to back out! When the green warning box appears, click No to abort the install process or Install to start the installation. If you click Yes, SUSE formats your hard disk and installs the selected packages. After installation finishes, SUSE reboots. (You can remove the CD or not, as you choose. SUSE will, by default, boot to hard disk even with the CD in.) Configuration Settings Although SUSE is now installed, the first time SUSE boots from hard disk you are immediately presented with a screen that asks you to do some basic configuration. With the YaST root password screen in front of you, continue to the next step. 16. Root Password. Enter the root password (twice). Enter up to eight characters. DES is the default encryption type used to protect your password. (You can select Expert Options to choose MD5 or Blowfish instead.) Refer to Chapter 6 for suggestions on choosing a good password. 17. Network Configuration. YaST probes to find any network cards, DSL connections, ISDN adapters, or modems connected to your computer. Select any of those items that appear on the screen, as appropriate, to configure it. For example, select Network Interfaces to view any installed network cards. You can configure any card found to use DHCP (if available) or your own network settings to connect to the LAN and/or the Internet. (See Chapter 5 for information on configuring Internet connections.) During network configuration, you also have an opportunity to configure your firewall. One nice feature is that you can allow ssh requests through your firewall, so you can login and transfer files to and from the machine using OpenSSH tools (ssh, sftp, and so on). Caution

336 Part III . Choosing and Installing a Linux Distribution You can install all packages that are selected by default in the OpenSUSE install process from the OpenSUSE 10.0 disk #1 image that comes with this book. If you want to install additional packages, you need to either get CDs 2 5 yourself or install the packages over the network after the initial install is complete. Choose each group selection to see the specific packages in each group. Check boxes indicate which packages you want to install. It s a good idea to look through this list to see what you are getting. If you change any of the selections, click the Check Dependencies box to make sure that all packages that other packages depend on are being installed. Figure 10-3 shows the YaST module for adding, removing, and finding out about software packages. Figure 10-3: Install and remove software using the YaST software module. The YaST software packages module used during installation is the same one used on a running SUSE system (in Figure 10-3, it s shown on a running SUSE system). In either case, you can find out a lot of information about packages that interest you. With a package selected, click tabs in the box at the bottomright corner of the screen to see its description, technical data (its size, packager, and so on), dependencies, and version numbers. 12. Booting. Select Booting to see the information that is added to your boot loader (GRUB, by default, but you can use the LILO boot loader as well). The boot loader includes the information needed to boot Linux: the location of the boot loader, default operating system to boot, and other information. Note

Chapter 10 . Running SUSE Linux 335 7. Desktop Selection. Choose KDE, GNOME, or Other to set your desktop environment. KDE is most commonly used with SUSE. With Other, you can have a minimal graphical interface or completely text-based (no GUI). Installation Settings The installation settings that appear allow you to select either the Overview or Expert tab. Review the settings on these tabs. The following steps describe how you might want to change the values shown. 8. System. Select System to probe your computer hardware. The result is details about the type and model of each hardware item on your computer. You can save this information to your hard disk (if there is an available partition) or to a floppy disk. Click Details to see further information about any selected item. You might find this information useful if, for some reason, the hardware is not properly configured after the install is complete. It will give you information you need to search the Web or ask a question to a Linux forum about your hardware problem. 9. Keyboard layout. Make sure the language/country associated with the keyboard you are using is properly identified. 10. Partitioning. Partitioning is very important, especially if you want to protect any data currently on your hard disk. Select Partitioning. SUSE recommends a partitioning scheme. (If your disk is already partitioned, SUSE tries to use that scheme.) You can simply accept that scheme (choose Accept Proposal As-Is and click Next) or elect to create a custom partition setup. The Expert partitioning selection enables you to use a partitioning interface that is very similar to Disk Druid. See the description of partitioning in Chapter 7 for information on partitioning your hard disk. If you ever plan to move your partitions around with a tool such as Partition Magic, you should assign your Linux partition to the ext3 file system type. (If you are an expert and want to use the fdisk command described there, press Ctrl+Alt+F2 to get to a shell, run fdisk, and then press Ctrl+Alt+F7 to return to the graphical installer.) 11. Software. Select Software to see a list of packages available to install on your hard disk. The default Desktop install offers the following package groups of software: Graphical Base System X Window System, window managers, graphics libraries, and so on. KDE Desktop Environment The KDE desktop and related applications. Help & Support Documentation The SUSE help system and related tools.

334 Part III . Choosing and Installing a Linux Distribution . NFS To use an NFS server instead of an FTP server, type the following: install=nfs://10.0.0.1/install Other installation media that are supported include hard disk (with the SUSE software installed on a different hard disk or partition on the local computer) and Samba (where the software is on an SMB share from a Windows or other Linux system). Starting Installation Here are the steps for installing SUSE Linux on your hard disk, using the network install CD: 1. Insert the installation CD in your CD drive. Reboot the computer. The SUSE installation boot screen appears. 2. Installation type. Use your arrow keys to highlight Installation and then press Enter. The YaST screen appears to begin installation. Sometimes installation can fail because the computer hardware doesn t support certain features, such as power management (ACPI or APM) or DMA on hard drives or removable media. For those cases, you can try starting installation by selecting ACPI Disabled (which turns off ACPI) or Safe Settings (which turns off ACPI and APM as well as turning off DMA for any IDE CD, DVD, or hard drives). The remaining steps in the installation process are divided into three sections: Preparation, Installation Settings, and Configuration. Preparation Continue with Step 3 to prepare for installation. 3. Language. Select the Language you want to use for your SUSE Linux system and click Next. The License Agreement appears. 4. License. Read the Novell Software License Agreement. If you agree, select Yes and click Next. (If you select No, it ends the install process.) You are prompted to select an install mode. 5. Mode. Here you can choose whether to run a new installation or upgrade from an older version. Choosing to upgrade an existing SUSE Linux installation will take more time than a clean (new) installation. For either an upgrade or new installation, you should back up all your data before you start. 6. Clock and Time zone. Select the time zone in which you re located. If the time is wrong, click Change, and type your new date and/or time and click Apply. Select Next to continue. You are asked to choose a Desktop. Caution Note
