Title: Moving to the Linux Business Desktop

Moving to the LinuxBusiness Desktop
  • It's time!
  • Say "Goodbye" to Windows
  • crashes, viruses, hassles,
  • and costs!

Based on the book by Marcel Gagné
The Birth of Linux
  • From torvalds_at_klaava.Helsinki.FI (Linus Benedict
  • Newsgroups comp.os.minix
  • Subject What would you lik to see most in
  • Summary small poll for my new operating
  • Message-ID elsinki.FI
  • Date 25 Aug 91 205708 GMT
  • Organization University of Helsinki
  • Hello everybody out there using minix -
  • I'm doing a (free) operating system (just
    a hobby, wont be big and professional like gnu)
    for 386(486) AT clones. This has been brewing
    since april, and is starting to get ready. I'd
    like any feedback on things people like/dislike
    in minix, as my OS resembles it somewhat (same
    physical layout of the file-system (due to
    practical reasons) among other things).
  • I've currently ported bash(1.08) and
    gcc(1.40), and things seem to work. This implies
    that I'll get something practical within a few
    months, and I'd like to know what features most
    people would want. Any suggestions are welcome,
    but I won't promise I'll implement them -)
  • Linus (
  • PS. Yes - it's free of any minix code, and
    it has a multi-threaded fs. It is NOT protable
    (uses 386 task switching etc), and it probably
    never will support anything other than AT-hard
    disks, as that's all I have -(.

  • What is Linux
  • Linux is a kernel, the brains or control center a
    collection of software packages, usually referred
    to as a Linux distribution. Popular
    distributions include Mandrake, Red Hat, SuSE,
    Debian, and others.
  • Is Linux really FREE?
  • TANSTAAFL (Robert A. Heinlein)
  • A free download will still cost you connection
    time on the Internet, disk space, time to burn
    the CDs, and so on.
  • "Free as in speech"
  • "Free as in beer"
  • Distributed under the GPL

  • Linux is distributed under the GNU General Public
  • in essence, the GPL says that anyone may copy,
    distribute, and even sell the program, so long as
    changes to the source are reintroduced back to
    the community and the terms of the license remain
    unaltered. Free means that you are free to take
    Linux, modify it, and create your own version.
    Free means that you are not at the mercy of a
    single vendor who forces you into a kind of
    corporate servitude by making sure that it is
    extremely costly to convert to another
    environment. If you are unhappy with your Linux
    vendor or the support you are getting, you can
    move to the next vendor without forfeiting your
    investment in Linux.
  • In other words, "free as in speech", or simply

What do you gain?
  • No operating system will ever be perfect, but
    Linux is getting pretty close. With Linux,
    you'll gain
  • Better Security
  • Increased Stability
  • Power from your OS
  • Money (saved!)
  • Freedom from legal hassles

What do you lose?
  • Hardware and peripheral support
  • Some hardware is designed to run exclusively with
    Windows (eg Winmodems). Linux developers
    continue to work on drivers
  • Shrink-wrapped software.
  • Hot new games or popular packages may not be
    available at your local software store. Still,
    thousands of packages exist for Linux a click
  • A step into the unknown. Learning curve.
  • Even moving from 95 to XP will take some

What about support?
  • Corporate support through large vendors like Red
    Hat, SuSE, Mandrake, IBM, HP, and others.
  • Worldwide community support IRC chats, Linux
    User Groups, mailing lists
  • Linux Documentation Project
  • http//
  • HOWTOs, man pages, books
  • Linux technical support "among the best"

Getting Linux
  • Buy a boxed set of Red Hat, Mandrake, SuSE,
    Xandros, Lindows, and others.
  • Download ISOs (images) from the vendors or visit
  • Borrow disks from a friend, copy, and burn your
  • Redistribute them yourself

Linux with Windows?
  • Set up a dual boot system
  • Use VMWare and run Linux, BSD, or Windows
  • http//
  • Win4Lin, if you only want Windows
  • WINE or FREEDOS for simple applications
  • CrossOver Office
  • lets you run some of the more popular apps
    without requiring a copy of Windows.

  • Modern Linux distributions are even easier to
    install than Windows
  • Most will repartition your drive automatically or
    resize it to allow for a Linux/Windows dual-boot
  • Answer a few questions, click Next a few times
    and you are running Linux

Knoppix CDROM
  • "Moving to the Linux Business Desktop" comes with
    a customized version of Klaus Knopper's excellent
    Knoppix distribution.
  • Run Linux from the CD without installing it.
  • Great for "getting your flippers wet"
  • Note that running from the CD is substantially
    slower than running from an installed Linux
  • Feel free to copy and redistribute the CD

Desktop Options
  • KDE (K Desktop Environment)
  • mature, friendly, integrated, and slick
  • east to use
  • first choice for new desktop users
  • GNOME (GNU Network Object Model Environment)
  • also very nice with GNOME 2 releases
  • IceWM, WindowMaker (dock apps!), XFCE

Desktop Customization
  • KDE is very customizable
  • icons, fonts, colors, backgrounds, window
    decorations, themes, sounds, etc
  • desktop can be themed to
  • suit any personal tastes or to
  • adhere within a corporate
  • look and feel
  • Visit http// for lots of ideas

File Management
  • KDE's file manager is Konqueror
  • Konqueror is many things
  • file manager
  • web browser
  • CVS browser
  • image gallery and digital camera tool
  • universal viewer

  • Konqueror
  • showing off
  • file manager,
  • icon view,
  • and shell
  • access.

Installing Packages
  • Many options starting with KDE's Kpackage tool
  • Command line rpm, urpmi, or apt-get
  • Synaptic for apt-get
  • apt-get for RPM
  • Yum (http//
  • Compiling from source (easier than it sounds)
  • extract and build five-step

Working with Hardware
  • When purchasing hardware in a store, always ask
    whether it runs with Linux -- even if you already
    know. It lets retailers know that there is
    indeed a Linux market out there.
  • Use the "kinfocenter" command to check out your
    system's hardware.
  • lspci and lsusb can be used at the command line
    to identify PCI and USB hardware

KDE Info Center
  • kinfocenter
  • knows all about
  • your system's
  • hardware!

Printers and Printing
  • Linux has excellent printer support through CUPS
  • Buying a printer?
  • visit http//
  • Add new printers using KDE's control center, the
    "kcontrol" program. Look under the control
    center's Peripherals menu and use "Administrator
    Mode" to create and add printers.

Add Printer Wizard
  • Just point
  • and click
  • your way to
  • adding a new
  • printer.

Internet Access
  • Linux supports pretty much every form of network
  • Dial-up through Kppp or wvdial
  • Cable modem connections through dhcp
  • ADSL
  • Modern distributions provide wizards for getting
    you connected, like Mandrake's Drakconf tool or
    SuSE's YaST2.

Dial Up Configuration
  • KPPP makes it
  • easy to set up a
  • dial up Internet
  • connection.

Part II Serving up the Desktop
  • Behind every great desktop operating system,
    there is a great server, providing users with the
    tools they need to get their work done. This
    includes Internet access, the routing of e-mail
    and instant messages, intelligent sharing of
    resources with co-workers, centralized backup,
    printing, faxing, Web services, and more.
  • Modern Linux distributions offer all of these
    things along with the tools to maintain and
    administer the information powerhouse your office
    will become.

Web-based Adminstration
  • Webmin is an excellent all around administration
    tool for Linux (and Unix) systems. It's interface
    is standard across distributions and you can
    administer your systems from any browser.

User and Group Adminstration
  • As you might expect, this is another task that
    Webmin handles rather well.
  • On the KDE desktop, there's also the KUser tool
    which provides a friendly, easy to use
    environment for every aspect of user and group

Backing up your data
  • Linux comes with many of the classic backup
    tools, including cpio, tar, dump, and restore.
  • There are also some great graphical tools. You
    can even back up to your CD or DVD writer using
    the superb K3b. It's also great for making audio

Electronic Mail Servers
  • Most Linux distributions offer a choice of mail
    transport agents (MTA) with Postfix being among
    the most popular.
  • Your old friend, Webmin, is a great way to
    configure and administer your Postfix system.

LDAP (Lightweight Directory Access Protocol)
  • Think of it as directory assistance for your
    network. User information, address books,
    security information, and more.
  • The answer to all your directory needs are as
    near as your Linux installation and OpenLDAP.
  • Administration tools you'll want to check out
    include GQ and Luma.

  • There's no need to invest in a Windows server to
    handle file and printer sharing. Samba does it
    better, faster, and won't cost you a penny in
    license fees.
  • Webmin and SWAT are great tools for administering
  • Smb4K is a great way to handle Windows shares on
    your Linux desktops.

NFS (Network File System) and NIS
  • When it comes to file sharing, you've got a
    number of options. For instance, you can choose
    from Samba, CODA, AFS, and others. There's also
    the grand-daddy of file sharing protocols and
    it's still very much in use. That's NFS and it
    has been around since the 80s.
  • NFS is a client/server system that enables a
    local directory on the server to be made
    available to other client systems. Once it is set
    up, the whole thing can be completely automatic
    and transparent.
  • How would you administer this? Webmin is there
    and ready to help. Of course, you could always
    use your old friend, the command line.

Thin Clients
  • Looking to run modern, high end desktops on
    older, more modest hardware? Linux thin clients
    came make that possible.
  • Thin clients allow you to set up workstations
    with minimal Linux installations that offload
    most of the work to a powerful central server.
  • Linux thin clients can save you money and
    administration time because you only need to take
    care of one machine. Clients boot from the
    network and download their desktops from the
  • One of the most popular thin client
    implementations is LTSP, the Linux Terminal
    Server Project at http//

Remote Control
  • Imagine dealing with PC problems on the other
    side of your office without leaving your desk.
    That's the magic of remote control applications.
  • With VNC or KDE Desktop Sharing, just connect and
    you are as good as there.
  • Linux also comes with rdesktop, a great program
    for connecting to Windows Terminal Server.

Electronic Mail Clients
  • Linux provides many different packages for
    electronic mail. From a variety of text-only
    clients to full featured graphical programs, you
    won't lack for anything.
  • Text only
  • mutt, pine, elm are among the more popular
  • Graphical
  • Kmail, Evolution, Sylpheed, Mozilla, and more

Kmail Features
  • Integrates beautifully into KDE desktop
  • Supports IMAP, POP3, multiple accounts
  • Includes privacy features like PGP/GnuPG
    encryption, user defined filters, and SSL/TLS.
  • PGP/MIME and S/MIME attachments
  • Fully configurable interface (colors/fonts)
  • Multi-level folders, drag and drop, spell
    checking, multiple identities, and more . . .

KDE's Kmail

Evolution Features
  • Integrates email, calendaring, scheduling,
    contact management in one place
  • Users coming from Outlook will feel right at home
    with the interface design.
  • With "Ximian Connector", Evolution can easily
    integrate into an MS Exchange environment.
  • Supports IMAP/POP and secure connects
  • Multiple identities

Evolution Email more

Other Email Options
  • Web-based email applications like Squirrelmail
    are an excellent choice for remote access.
  • Linux also provides a number of text email
    clients that are very popular.
  • mutt, pine, elm
  • There are other graphical clients as well
  • Aethera, Sylpheed, Balsa

Getting Organized
  • Keeping on top of the many appointments,
    meetings, and todos on your list just got easier.
  • Linux comes with some great calendaring suites.
    You've already met Evolution with its
    Outlook-like interface.
  • There's also KOrganizer (part of the Kontact
    suite). You can even synchronize it with your
    Palm PDA.

Web Browsing
  • As with Email, Linux has a number of options for
    web browsing, in both text-only and full
    graphical mode.
  • Text-only browsers include
  • links, lynx, w3m (limited graphics capability),
  • Graphical browsers
  • Konqueror, Mozilla, Galeon, Opera, more

Konqueror Features
  • Aside from being a great browser, Konqueror is
    also a powerful file manager.
  • Supports Java, JavaScript, Netscape and Mozilla
    plugins (Flash, RealAudio, etc)
  • HTML 4.0, SSL, CSS 1 and 2
  • Tabbed browsing, multi-pane, multi-featured!
  • Use it to block pop-up ads, cookies
  • Will impersonate many other browsers

Browsing with Konqueror

Mozilla Features
  • Mozilla is a combination web browser, email
    client, HTML editor, IRC chat client, and more!
  • Standards compliant, SLL,
  • Also stop popup ads, cookies, etc.
  • Features tabbed browsing
  • Available for Linux, Windows, Mac OS/X
  • For Mozilla's lightweight 'browser only', check
    out Mozilla Firebird.

Browsing with Mozilla

Keeping Up To Date
  • Bugs are discovered and fixed all the time.
    Programs are in a constant state of fine tuning
    and improvement. For security reasons, or simply
    from a functionality standpoint, it makes sense
    to keep up to date and Linux provides many
    opportunities to do so.
  • Keep in mind that a high-speed connection is
    desirable if not essential. While updates can be
    easy, packages can be large and downloads over a
    modem connections may take a long time.

Updates by Distribution
  • Red Hat Linux
  • up2date
  • Mandrake
  • urpmi / Mandrake Update (or through drakconf)
  • SuSE
  • Online Update through YaST2
  • Debian
  • apt-get

Word Processors
  • As with so many things in the Linux world, there
    are a lot of word processor choices. The most
    powerful is Writer, part of the
    suite (and its commercial cousin, StarOffice).
  • Microsoft Word users find themselves very
    comfortable with OpenOffice.
  • More than 99 Microsoft Word compatible.
  • "Moving to Linux" was written with OO Writer.
  • Other options include Abiword, Kword, etc.

Working with OO Writer

  • OpenOffice Calc, part of the suite
    provides near perfect compatibility with Excel.
  • Features will be familiar to Excel users.
  • Other options include the very capable Gnumeric
    spreadsheet and Koffice's Kspread.
  • Gnumeric is particularly excellent at recreating
    Excel's features and format.

Working with OO Calc

Presentation Graphics
  • OpenOffice's Impress is the presentation graphics
    suite of choice in the Linux world, and my
    personal recommendation. This "PowerPoint"
    presentation was done with Impress.
  • Nearly perfect PowerPoint compatibility
  • Format and functionality will also be quite
    familiar to Powerpoint users.
  • There are many other presentation packages, but
    you might consider trying KDE's KPresenter

Working with Impress

Scanning Images
  • Most popular scanning tools are XSane and Kooka
    (the GIMP also features scanner plugins)
  • Kooka is KDE's scanning tool. It is friendly and
    easy to use. With gocr, Kooka does optical
    character recognition (OCR)
  • XSane, while powerful, may not be quite as
    polished looking. On the other hand, it also
    makes a great fax machine and photocopier.

Scanning Images and Text

Working with a Digital Camera
  • The magic of interfacing with digital cameras is
    done using the gphoto2 libraries which currently
    support almost 500 popular cameras.
  • Konqueror is a great tool for accessing you
    camera and manipulating images.
  • Have a look at digiKam as well. This is a slick,
    powerful, easy to use, digital camera and photo
    album maintenance tool.
  • http//

Image Manipulation
  • The GIMP is an amazingly powerful image
    manipulation package (similar to Adobe PhotoShop)
  • Create professional looking logos in seconds.
  • Easily manipulate digital camera images, adjust
    light levels, get rid of red eyes, and add
    special effects.
  • ripples, metallic embossing, borders, flares,
    shadows, canvas and cloth effects, distorts,
    blurs, and more!

Working with the GIMP

Instant Messaging
  • This form of always on, quick one-liner
    communication is no longer strictly the
    playground of kids and teenagers looking to chat
    with their friends. Instant messaging is now an
    important part of the business communication
    arsenal and Linux offers some great IM clients.
    The most popular are
  • Kopete
  • GAIM

  • This is a powerful, multi-protocol instant
    messaging client for Linux.
  • Part of KDE
  • Supports
  • Yahoo!
  • MSN
  • Jabber
  • AIM
  • Many more!

  • An excellent multi-protocol IM client.
  • GAIM supports
  • Jabber
  • MSN
  • Yahoo!
  • ICQ
  • and many others!

Video Conferencing
  • It may not be the
  • video phone we
  • were supposed to
  • have by now, but
  • GnomeMeeting
  • brings video
  • conferencing to
  • Linux.

The Future
  • I hope you've enjoyed this little tour of Linux
    and the Linux business desktop. With all the
    power, stability, security, fun, and flexibility
    at your command . . .
  • Linux is the future of computing!
