While many of you will already have (or perhaps claim to have) a mountain of experience in and around UNIX GNU/Linux, there are usually gaps that will need filled, since most of you learned things OTJ or as you needed to, but nothing more. The best way to complete this course is to come in and study the entire thing afresh, as if youve never seen UNIX GNU/Linux before. Dont take shortcuts or skip material, no matter what the urge - your grades during final testing will depend on knowing as much of the course material as possible, and knowing how to apply it in given hypothetical situations.SA @A8 GTk/Instructions for using DATC Classroom ComputersS1A PAd A  A T TO Getting StartedS'Ad A  A 3TynWe will first use the WindowsNT OS to get you started. This is because WinNT is the default operating system in this classroom, and you will find that Windows is prevalent on the job as well. You will discover that removing Windows and converting a given machine to (or cohabitate Windows with) Linux will actually become part of your routine within the IT industry.TK@When you choose a workstation, you will be prompted for a user name and password in order to log onto the NT network. Once you progress beyond Chapter 2, You are urged to stick with the computers that have removable hard drives, for the practical reason that you will be using a removable hard drive during this course. TOn the Windows NT machines, your username will be your last name followed by your first and middle initial. For example, if your name is Karey D. Barker, your username will be barkerkd. Your password will initially be password. The first time you log onto a workstation, you will be asked to change your password, then re-type it to confirm. You should use a password that is difficult for others to find out, easy for you to remember.A8 T|qWhen you have finished working on the computer or leave the desk, you should close all programs and log off of the Win NT computer. You can do this by hitting Control + Alt + Delete and selecting the Logoff option. There is no need to power down the computer in Windows NT, since it can be used by the next student to arrive. If you are switching to the Linux drive from WinNT, do the same thing, but select Shut Down at the menu. When you are done with the Linux drive, go to a clear prompt and type shutdown -h now to shutdown the machine. Once you power down, remove the hard drive and switch it back to the WinNT drive.T iTK CBT coursesS'Ad A  A 3T Due to the fact that the CBT course only work in Windows, you will have to use the Windows NT operating system to use the CBT exercizes - simply shutdown the machine, switch to the NT TF; hard drive, reboot into NT, and launch the CBT coursework.T'SAPdddT T_ Performing the Online exercisesS'Ad A  A 3T |There are two computers in the classroom that can access the Internet. They are workstation numbers NT-17 and NT-18, near the classroom desk. Please keep in mind that there may be other students who need to use the terminal, so only use the online resources that you need. The mandatory sites and resources are also printed and kept on file in the classroom for your convenience.S@APdddAd A A @3T: Intro To GNU/LinuxSA PAd THCourse SummaryS'Ad A  A 3T  TSA @T6Why this course is important:SA  TEven though Unix is more often a systems administrator tool, it is still quite common to find a Unix workstation at the client level. It is becoming even more common to find Linux rapidly taking the place of traditional Unix variants. The best way to learn how to administer a Unix GNU/Linux system is to learn it from the client-level perspective. If you dont know its basic operation, you cannot possibly administer it. Even if you never want to administer a Unix GNU/Linux system, you may discover that youll have to use one as a client. While we do cover quite a few sysadmin duties, they are included only because they are required for basic housekeeping on an individual Unix GNU/Linux machine, be it client or server.T8-We concentrate on GNU/Linux for two reasons: T}9GNU/Linux is the easiest and most accessible form of UnixS1APdddhA @WW8Num183TGNU/Linux is growing rapidly in popularity within the IT and Internet communities. This is because it is just as powerful and flexible as any other form of Unix, because it is available at little or no cost, and the source code for GNU/Linux is available at no cost to anyone who has the patience to tinker with it. (Try getting Microsoft to cough up a copy of the Windows 2000 source code :)S1APdddhA @WW8Num183T T,Course Information:SA  Tg\Students will gain a competent understanding of the skills necessary to plan, install, implement, and administer Linux - both as a user and as a basic systems administrator. The student will recognize that although Linux is a complex and powerful language, it is also a powerful tool, ready to serve anyone who has the skills to use it. You will find that the packet tends to skip chapters, only to go back to them later on. This is because although all of the information is useful, the order has been rearranged to make it easier to assist you in learning how GNU/Linux and Unix work. Also, unless specifically referred to as either UNIX V or UNIX in all caps, the term Unix is only used as a generic term, not as a mark of any specific product name. Lastly, most of the information about GNU/Linux can generally be translated to most Unix varieties.T+Proficiency Goals:SA  Tp,Learn a basic history of Unix and GNU/Linux.S1APdddhA @WW8Num423T>Plan and anticipate a typical Unix or GNU/Linux installation.

I also want to take the time to introduce you to the Open Source movement, since it is currently gaining a large following within the IT community, as well as among programmers and even corporations. While no one can confidently state the future, I can predict that the Open Source movement will become the way software companies do business in the coming years. This is because with Open Source and GNU, there is no longer any such thing as Software Piracy, Warez or cracks. You can copy the software to your hearts content. The consumer can do whatever they want (within reasonable limits) to the software they receive, and are even encouraged to improve on it by way of having the source code for that product, right there in front of them.SAPdddT"eOpen Source is also a boon to industry, which would otherwise have to shell out a lot of money just for access and user licenses...these would naturally become obsolete once an upgrade (or worse, multiple upgrades) became necessary. Companies, who would otherwise be forced to conform to a standard operating system, can now move towards the more innovative option of modifying the source code and the operating system to meet the exact (and sometimes unique) aspects of their particular business. This improves productivity by a huge margin, and by extension, it would improve the market that the company serves.SAPdddT"\The following modules will increase in difficulty and complexity as we go along, but they will all follow a basic structure, which is explained in full. However, these modules are not made to overwhelm you, but instead to challenge you as you progress through the course, as the things you learn in one module will apply to the next one you study. SAPdddTM"&The most important thing to have with you as you travel through these pages is a good attitude. Do not look upon the course as a chore to be done, but rather, look at it as a child would look at his or her parents automobile: Something complex, but something that he or she knows will be very useful to them some day soon... GNU/Linux, and by extension Unix, might indeed become very useful to you, especially if you intend to make computers and their use a career. But, you wouldnt be here reading this packet if you didnt know that already, no? SAPdddT'"SAPdddTK"About This Module and GNU:S&APdddA  T2" This module will cover philosophical and even semi-political arguments, presenting an entirely new business model and most likely shaking up everything you thought about the software industry. To be honest, the GNU GPL may even seem activist to those who are used to the idea that business should keep things proprietary. However, I can assure you that it is not activist in any way: It is merely a new way of doing business. GNU also eliminates many of the headaches that plague proprietary software: Pirating, Warez, and Counterfeiting are eliminated under the GNU business model. Fixes, patches and upgrades are faster, because more people can get to the actual source code and work on it. There is also a larger sense of community among those who practice and use the GNU business model - a sense that everyone is in this thing together. You also get a greater sense of ownership when you download and perhaps even modify software, especially because it is essentially yours to do with what you wish, within very few limits.SAPdddT"Know that GNU/Linux is not perfect - it relies on a large community of developers and supporters to maintain and improve the code, and to provide documentation and support for the vast array of hardware configurations out there. Also know that Linux is not yet made for Joe Six-pack (or anyone else who is computer illiterate) - it will require a little more initiative and knowledge than the standard desktop OS.SAPdddT TD9You will sometimes find that an application you need may not be available in Linux...this is changing rapidly, as Linux begins its inroads into the mainstream computer culture. Linux will also require more out of you than any other operating system; it will challenge you and it will sometimes vex you. However, the problems are not too tough to overcome, and you will end up educating yourself more than you ever thought possible. You will learn the ins and outs of your computer, more than you ever would with any other operating system. Finally, know that the GNU business model is most likely where the software community is heading, in spite of resistance from the larger companies such as Microsoft, who have made their fortune via proprietary (closed) software. This resistance is not ill-intentioned, but you will find that it is bothersome at times, and in some cases it will even be misleading. However, there is no such thing as a perfectly peaceful revolution, and the GNU/Open Source movement is exactly that - a revolution in how the computer industry does business.T TIn this module, I will provide you with both sides of the story, from GNU and the Open Source point of view, to the internal opinions and an honest study of GNU/Linux from the largest software company on Earth...Microsoft.TBefore we begin, allow me to explain some terms that may seem unfamiliar to some, either here or to be found later on in the module: TCracks (or Crackz): A common hackers term, referring to software that allows you to crack a registration code on software otherwise protected against piracy. This includes false CD Keys, algorithm generation tools which allows you to create a forged registration on shareware products, and any other software-based device that would enable you to use protected copies of proprietary software without paying for it. These are usually available on most Warez distribution websites.A8 TWarez: A common hackers term that refers to all pirated software released for general distribution, software that is usually found on websites.A8 TFUD: Fear, Uncertainty, and Doubt. This is a term you may find in the Linux community that refers to the actions (usually attributed to Microsoft) if intentionally confusing the general public, putting a fear into the public of someone or something, or to plant the seeds of doubt in the minds of the public in general. You might find that the term is used more often than necessary in some of the web-based texts.A8 TFPU instructions: FPU = Floating Point Unit, another way of referring to the math co-processor (which was once a separate processor, but is now built into the CPU itself.)A8 T" GNU: Gnus Not Unix. Many of the program names in Unix, including the UNIX name itself, were named originally as inside jokes by their creators. For example PINE (a very popular and stable text-only mail and news reader) stands for Pine Is Not Elm (ELM was the original text-based mail and news reader.) In case youre curious, even the name UNIX was a joke in and of itself The UNIX operating system is derived from Bell Labs original Operating System project known as MULTICS (uni from Multithose who know Latin real well might get the joke implied) To make it short programmers do have a sense of humor, even though the products they apply their humor to are quite serious indeed. Most of the Unix/Linux community carries this tradition on, even to today.A8 T T,Course Information:SA  TThis module is intentionally short, to get you started comfortably, and to get you used to the modules and how theyre laid out.T+Proficiency goals:SA  TB7To learn what GNU/Linux is, and what it can do for you.TdYTo get an idea of why GNU/Linux exists, and how it got as popular as it has become today.TVKTo learn where GNU came from, and what the Open Source movement stands for.TC8To get an idea of why people use GNU/Linux in particularT]%R Discover where it can be had, both for a slight cost and for free.T_Get to know a bit of comparison between GNU/Linux (or even Unix) and its closest relative, DOS.S5APdddAd A 3 TBModule ChecklistS'A PAd A T@'Check off each item as you complete it:SA  TiB1. _______Study: - The module summary page in this proficiencySAPdddhTO6- Chapter 1 (pg. xi to pg. 44) of Running Linux.A8 (6TSA @T|U2. _______Online: Visit the following sites, and read through them in their entirety:SAPdddpT'SAPdddpT; http://www.faqs.org/faqs/unix-faq/faq/part6/section-2.htmlSAPdddpA8 ;AU8 ;:http://www.faqs.org/faqs/unix-faq/faq/part6/section-2.htmlT; http://www.cab.u-szeged.hu/local/Linux/doc/lug/node14.htmlSAPdddpA8 ;AU8 ;:http://www.cab.u-szeged.hu/local/Linux/doc/lug/node14.htmlT' http://www.opensource.org/history.htmlSAPdddpA8 'AA8 '&http://www.opensource.org/history.htmlTBhttp://www.linuxjournal.com/issuebg/1376.html - What is GNU/Linux SAPpdddpA8 -AH8 --http://www.linuxjournal.com/issuebg/1376.htmlTEhttp://www.gnu.org/gnu/gnu-history.html - History of the GNU Project SAPpdddpA8 'AB8 ''http://www.gnu.org/gnu/gnu-history.htmlTR http://www.gnu.org/gnu/manifesto.html - GNU Manifesto.

It is actually nowhere near as frightening or foreign as many would have you believe...it is no longer an operating system restricted to college comp-sci engineers, outright nerds, and hackers. It has become (and will still become) easier than ever before to learn and use Unix in your day-to-day life, either at work or at home. TYou do not need a mainframe or high-powered mid-tier server to install and operate GNU/Linux...in fact; just the opposite is trueTGNU/Linux performs better on older (and slower) PCs than any other OS on the market today. For example: Windows NT 4.0 Workstation requires (on a practical scale) at the very least 200MB of disk space for just the basic operating system and a practical swapfile*. GNU/Linux on the other hand can be run from as small a space as 20MB on a practical scale, including the swap partition. Windows NT 4.0 Workstation requires, on a practical scale, at least 16MB of RAM and a Pentium or better CPU just to operate at all. On the other hand, decent workstation performance can be had with GNU/Linux on something far less powerful, say an Intel 486SX-25 with 4MB of RAM. **TIf nothing else, GNU/Linux gives you a perfect excuse to drag those dusty old 386 and 486 machines out of the broom closet at work, and put them back to work again - talk about recyclingT,Course Information:SA  TThis requires even more reading, but it will give you a good look under the hood, and to familiarize yourself with the basic GNU/Linux Kernel and, by extension, how the typical Unix kernel operates.T+Proficiency Goals:SA  TDTo learn the difference between DOS and Unix memory process handlingS3APdddhA @ 30005701223TAGet a quick look into what STDIN, STDOUT is, and how they operateS3APdddhA @ 30005701233Tl&Take a short look into what Pipes are.S3APdddhA @ 30005701243T|6Discover the concept of treating everything as a file.S3APdddhA @ 30005701253Tl&Learn about how Unix sorts directoriesS3APdddhA @ 30005701263Tk%See how Unix and DOS commands compareS3APdddhA @ 30005701273T|6Become familiar with the Unix command-line environmentS3APdddhA @ 30005701283T>Discover where it is you can get GNU/Linux, at low or no cost.S3APdddhA @ 30005701293Ty3Get an overview of what an installation will entailS3APdddhA @ 30005701303TMBrush up on the concept of partitions, then learn how they apply in GNU/LinuxS3APdddhA @ 30005701313TbSee how one would partition a DOS-loaded hard drive to accommodate more than one operating system.S3APdddhA @ 30005701323T iTWindows NT Workstation requires 110MB of space minimum (on an x86 architecture CPU) for just the OS alone, according to Windows NT Core Technologies (MOC course # 922, Microsoft Press.)

Having actual hands-on experience with an operating system not only reinforces the teaching, but will also allow you to become familiar and even comfortable with the *ix command-line environment.TvWhile most people have a bit of fear and trepidation at installing a complete operating system, especially one that seems completely foreign, there is no reason to fear this. Let it be known that the instructions are as complete as we can possible make them, and that an instructor will always be on hand to assist and advise when necessary, or even when needed. Do not worry that you will ruin any equipment ...as long as you follow the instructions completely, the worst that can happen is that you may have to re-install the operating system - that is why we provide you with a complete and empty hard disk drive to work with. TThis is where you begin to realize that Linux is not as easy to install as most other operating systems. However, it has become far easier recently, with the addition of Red Hats GUI install option, as well as the simple graphical installs performed by most Linux distributors. There will always be exceptions, but the Linux distributors are realizing that the easier they make an install, the more customers they attract, as GNU/Linux moves into the mainstream consumer market. TI will have you use the standard text install, since not all Linux distributions will have the GUI install routine. Also, you will find that Im keeping you to the command line once the system is installed, even though many distributions can take you right to a graphical logon screen. This is because you need to know the command line environment...as a regular user, knowledge of command lines will make troubleshooting and repair far easier if your desktop goes down - as a sysadmin, it is vital that you know the command line environment since many Linux servers drop the GUI altogether; a pure command-line environment takes up less space and overhead on a server. TYou will find that I ask you to go back and forth between Windows and Linux throughout the course - this is because the CBTs run on a Windows OS, but by happy circumstance, it will also to put you in a position to compare the two environments side-by-side as you progress.

Of course not - youre going to want bigger and better, just like anyone else with a computer...)TThis module, and the two following it, are the most important modules in this course - they will give you a close look into what actually happens behind the scenes, and how you can manipulate these happenings. While most of you will probably not go on to become Unix systems administrators, it is vital that you pay close attention to the following three modules, since they are just as vital to the home user as they are to the systems administrator. TAfter all, what good is the worlds most powerful and flexible operating system if you dont know how to control it? Once you learn how to gain that control, you will gain quite a bit of satisfaction along with it. This is because Unix lends itself more to the independent spirit, while quite a few other operating systems are made instead for those who would prefer to have the operating system control them, as opposed to the other way round.T,Course Information:SA  TThis is the first of three modules designed to give you a look at what is affectionately known as the guts of GNU/Linux, and by extension, Unix.

No matter which operating system you have, youre always going to have to bring it up to the newest software (and hardware), or else your machine will slowly become old and decrepit, gathering dust in places like your garage or in some far-off closet at work somewhere. While no computer is immune to the need for upgrades, Unix has the unique ability to upgrade nearly all of its software without having to shut the machine down! While most other operating systems require a reboot (or multiple reboots, as in Windows NTs case), a Unix machine will only need a reboot under specific circumstances, most of them directly related to either hardware or kernel upgrade issues.A8 BT,Course Information:SA  T"This module continues with basic sysadmin tasks, but this time we concentrate on upgrades, archives, compiling the kernel, and upgrading device drivers.

T`!UThink of your Unix machine as a car. In earlier chapters, you were just barely beginning to learn how the machine youve eventually built actually works, the principles behind its operation, and what to do with it under the hood. Now, were going to take this machine out of the garage and teach you how to actually drive the thing - that is, to put it to useful work. The beauty of Unix, and by extension GNU/Linux, is that you can make it do different things for you. Carrying our little car analogy further, we can say with confidence that a Linux-based machine can be, all at once or in turn:T7,A sporty, yet powerful convertible (games), T]RAn 18-wheeled semi-tractor capable of heavy loads (database or application server)TNCA minivan (word processing and other mundane, but necessary, tasks)T.#A school bus (educational software)T:/A tank (firewall and security-related software)TI>A tow truck (server dedicated to network backups and restores)TOr?T TNotice that the list is incomplete. This is because GNU/Linux, like any competent operating system, is constantly evolving and growing along with the industries (and consumers) that it serves. TxmBut let us boil it all down to this: How valuable is a computer to you, if you cant actually do anything useful with it besides keep it running for its own sake? Be it for games, reports, spreadsheets, or even as a working server within a network, a Unix machine is only as useful as the job it performs, and it is now time that you learned how to make it perform.T,Course Information:SA  TUJWe will begin by introducing you to the most basic of all computer tools: TEditors (programming, shell script editing, text editors, etc), Text tools (to turn that boring monospaced text into something worth reading), Graphics (to add that oomph to your text presentation), and Printing (to get the results on paper.)

You may also burn as many copies as you like, and distribute them to friends, acquaintances, etc, but only if you provide a copy of the GNU General Public License with it, and follow all applicable GNU GPL provisions. Finally, I highly recommend that you complete your proficiency in Unix and GNU/Linux by taking the next set of courses, involving Sair Inc. Linux/GNU Certification.T7Regards from your instructors,SA @TSA @TSA @T TM4Thomas J Miller jr Kimberly Ziebarth Stephen AllenSA @TSA PT T.Book II:SA @3 T'Appendices and Labs 3T@'Lab 1: Planning a Unix Install StrategySA PT TBefore you even think of shutting your computer down to flush and install a Unix operating system, you must sit down beforehand and learn about the computer youre using. Unlike Windows Plug-and-Play or DOS universal hardware requirements, Unix is a very demanding system that requires you to know what hardware settings and parameters you use and have. Failing to know these settings, or worse, guessing at them, can lead to problems ranging from a failed install to a wrecked monitor. T}The reason lies in the fact that Most DOS and Windows-based operating systems will usually intercept and kill any process call that looks as if it will destroy the hardware For example - Windows NT completely insulates hardware from any direct software manipulation by the user, as does the dynamic resource allocations found in most Plug-and-Play compliant operating systems. TUnix on the other hand does not insulate the user from the hardware. This reduces overhead, and allows more processing power to be sent towards the applications, instead of being wasted by the operating system. To put it in simple terms, Unix assumes that you know what youre doing, and wont try to second-guess you. Windows and MS-DOS assume that you dont know whats inside your computer at all, and acts accordingly, which, as a result, wastes extra processing cycles.TIn order to save yourself time and stress, it is usually wise to think ahead, and lay out exactly what you have, and what you want to do with it. During setup, you will be asked to specify partitions, including your root partition, swap-file, and data file partitions. You will also be asked what kind of video card chipset you have, the refresh rate on your monitor, and various other items that you really wont be able to look up during install. T.How to use the sheet:SA  TIve built a basic planning sheet, Appendix C, to help you organize and prepare your strategy for partitioning and installation. Here is how to gather the information youll need to know, while your computer is still running Windows.T3(First, get all the information needed TP "For your X-Windows Video Settings:SAd 3T TFirst, go to Display Properties (put the cursor on an empty part of the desktop, right-click, then select and click Properties.) Select the Settings Tab. Write down the listed Refresh Rate as indicated in the Worksheet.A8  A8 TuSelect Display Type. Write down the manufacturer and the Chip Type (Chipset) information. (In this classroom, youre looking for the Trident 975 chipset) Also take note of the memory capacity. Since youd normally have to go into the box physically to determine whether or not it is AGP, I will give that part of it away these are AGP video cards. Make sure to note this fact in your worksheet by circling AGP as appropriate. The Monitor type should be written in the monitor case, right up in the corner of your monitor. Once you have the information you need, hit Cancel to insure that nothing is changed in the Registry. A8 A8 ;ATA For the Hard Drive:SAd 3TNCOpen the blank Unix classroom hard drive carriage, looking at the case of the actual HDD. Write down the information you find on the case, which includes Cylinders, Heads, and Sectors (CHS), as well as capacity. You will not need to know these immediately, but it will familiarize you with the drive that you will be using.T TC For the Network Card:SAd 3T3Right-click on Network Neighborhood, and select Properties. Select the Adapters tab. The name and type of NIC should be listed right there. Write it down youll use it later. Hit Cancel to back out of the window without altering anything.A8 #A8 0:A8 GOA8 TSA PTK%The Hard Drive Partitioning SchematicSA @3 T T_TThis graphic is put on the sheet to give you a visual tool to help you mark the proportions of HDD space used to plan your partitions. Draw in the lines marking off the different partitions youll need, according to the following mount points/ needed partitions. Use the completed drawing to form a rough estimate of each partitions size:TXM/swp, or Swap partition. This partition should be at least as large as the amount of RAM you have in the system. Since the machines in this class have 64MB of RAM, it follows that the swap partition has to be at least 64MB large. A swap partition of up to 128 MB is possible in this configuration, but do know that any swap partition larger than twice your RAM will not improve performance by any appreciable amount. However, keep in mind that a swap partition is permanent, and if you add RAM to the machine, you wont be able to increase the size of the Swap partition without resorting to fdisk. If you dont leave enough free space in your HDD for a new (or larger) Swap partition, youll have to likely re-install GNU/Linux completely just for a RAM upgrade. A good rule of thumb is to make your swap partition as large as the maximum amount of RAM you plan to install in this particular machine (consider that the average life expectancy of a PC is about 2 3 years, before obsolescence makes hardware upgrades useless. Most companies replace their machines once every two years, on average.) Tk`/, or Root. The Root partition is exactly what it says this will be the root of your system, where the Kernel and vital operating system components will live and operate. This will also be your bootable partition, so make note of this on your worksheet. Make this partition at least 500MB large, but 1GB is a good size, to allow plenty of room for expansion. Minimum size can be as low as 150MB, but remember that you will have to operate this machine after installation, and adding components or recompiling the Kernel will leave even less free space to work with, which will affect performance greatly. T/usr where your users accounts and account information is stored. However, it is best to leave room for the next partition as well. T/home is the partition where users home folders reside. Here, you would have to take into account just how many users you will anticipate Make this a good-sized partition, since users will always add things to their home folders, and will rarely remove them. A good size for this class is around 500 MB or so, but in the typical network you should expect to use a general rule of 10-25MB or more per user. Most Internet Service Providers still use the OMB rule for users This means setting aside roughly OMB of space for a user to put up a WWW homepage, perhaps read and store their e-mail, etc. This is all done in the /home partition if you set one up.TOnce youve drawn it out Write down your estimated information in the next section, which lists partition name ( /dev/hda1-4 , since you can have only a maximum of four partitions on any hard drive. ) asks if each partition is bootable (choose your root partition.) , size (use the schematic above that youve drawn out as a guide to finalizing size in MB), type (Linux Native, or Swap File), and the mount point for that partition (as listed above) A8 T And thats it. Now take this information to the instructor for approval and to get a blank HDD to install your copy of GNU/Linux.S9APAd A @3TZ 2Lab 2- Installation of GNU/Linux onto a hard driveSA PAd T TAfter determining how you will partition the hard drive, the next step is to actually setup your hard drive, install GNU/Linux, and configure your machine. You will start with a blank 4.3GB (or larger) IDE hard disk drive, and will create the necessary partitions, install the mount points, install a bootable copy of the GNU/Linux Kernel and all components necessary for completion of this course. TThere will be a hard disk assigned to you from the instructor. Make sure you understand that, while no one else will be using it for the duration of the class, the drive is to remain here, in the classroom. You will be responsible for that hard drive during your entire time in this course. If you decide to take the advanced systems administration course, you will also use the drive youve worked on in this course, with all of the data and information intact. T T*Before you Begin!SA TpeMake sure you have enough time to install the systemit will take about 1 to 1-1/2 hours to complete.TWLWiththat one item out of the way, you can now proceed to the install itselfTU#The Initial setup and boot process:S'Ad A  A TaFind a computer with a removable HDD carriage in it (this carriage sits under the CD-ROM drive.)

T TYoull notice immediately that the root partition gets renamed hda1, while the swap partition gets renamed hda5. This is because your root partition is by default going to be considered as hda1 (this used to not always be the case, but standardization in Red Hat software almost demands that the root partition become hda1. The swap partition gets renamed hda5 so that it doesnt become confused with the four primary hard drive partitions. T TAdd all other partitions accordingly.

TH End of Lab.S2Ad A  A A @TS!Lab 3 - Installing and Using LILOS'A PAd A Tw 2Materials needed: A copy of Win98 OEM w/ boot diskS(Ad A A @3T TLILO, or Linux Loader, is a multi-purpose tool that can load your choice of multiple operating systems on your computer at boot time. WindowsNT has a similar item known as boot.ini. LILO writes itself into the master boot record of the IDE primary master hard drive (/dev/hda1, or, if you have SCSI the drive will be SCSI ID 0 or Linux ID /dev/sda1.) and will remain there unless removed within Linux, or written over by another operating system. In this lab, we will remove the default LILO that was written in your MBR when you installed Linux, and replace it with Windows98 while Win98 is installed. After a base copy of Win98 is installed, we will then go back into Linux and re-install LILO, then edit it to include a boot option for Win98. Even though you are unlikely to use Windows 98 for the rest of this course, you will need to do so here, if only to show you how to manipulate and install LILO without damaging other operating systems that may be resident on your hard drive.TIf you have any questions, at any time, please get hold of an instructor immediately - do not simply assume; instead refer to material when needed, and the instructions both in this packet and in the reference books will walk you through the process.T T Make a LILO boot floppy from the command line. Format a blank floppy with the command fdformat /dev/fd0 (do not mount the floppy beforehand.) Page 130 of your Running Linux textbook will walk you through the steps for making a boot disk. Once you have made the boot disk, then shutdown your machine and reboot, using only that disk (instead of relying on the hard drives MBR to boot for you, that is. You will basically be creating a way to get into and load your Linux partition after LILO gets wiped off of your hard drives MBR by Win98.)S1APdddA @WW8Num48A8WhA8 3TNow, overwrite the hard drives MBR (where LILO normally resides.) We will do this as a demonstration, by taking a DOS floppy, booting with it (after shutting the machine down appropriately), and running fdisk /mbr . This will destroy your hard drives master boot record, replacing it with a copy of MS-DOS master boot record. You will not be able to boot to Linux from just the hard drive after this is done. S1APdddA @WW8Num27A83TPShutdown the machine once more and remove the DOS floppy. Take your Linux boot floppy you had just created and, and boot into Linux with it. This will load the Linux kernel and launch the Linux partitions on your hard drive. Watch the boot process and make sure everything boots normally. Make sure that you do not configure LILO as a secondary boot loader, but instead make it the primary. As always, refer to the instructions in pages 132-134 of Running Linux. Further instructions are below...S1APdddA @WW8Num27A8 7:A8 3TRe-write the MBR so that LILO once again owns the MBR. Refer to page 132-134 for full details. Include both Win98 and Linux in /etc/lilo.conf. Use vi (instructions for vi are in the book Unix in Plain English, page 126-128.) Basically, type the command vi /etc/lilo.conf which will bring up the configuration file under the vi editor. To insert text, type i to insert text, using the arrow keys to move around the document as needed. Hit Esc to get out of insert mode when youre done modifying the document. Finally, when youre sure you want to finish and quit vi, make sure youre out of insert mode, then type :wq to exit vi - this will write your changes to the file and quit vi. S1APdddA @WW8Num27A8 A8A8eg3TwBoot into Linux from the hard drive, then reboot into Windows 98, both by using LILO. Show the instructor your results.TLLab 4: Mounting FilesytemsS'A PAd A T <Materials Needed: A floppy with a DOS text (*txt) file on itS(Ad A A @3TF A CD-ROM with any title on it.SAPdddTThis lab will walk you through the steps necessary to mount and automount filesystems as needed. You will use this lab to first learn how to manually mount removable media such as your CD-ROM and floppy drive, since Linux (and by extension Unix) requires that you notify the kernel that there is additional storage media added to the system, and to tell it what type of filesystem that media uses. This is to inform the kernel exactly what type of filesystem is being used on that media: Linux can see and access media that have been formatted in DOS, ext2 (Linux), WindowsNT NTFS partitions, and even Macintosh... By comparison, Windows currently will not allow such a thing to happen*, and Macintosh allows only limited access to DOS media, but even then only under special circumstances. In short, the payoff of mounting a filesystem manually is in the increased flexibility in the filesystems open for use in Linux.T4)*Windows does have limited accessibility among its own proprietary filesystems: WinNT 4.0 can only access FAT16 and NTFS partitions, while Win98 can only access FAT16 and FAT32(vfat) partitions. Windows 2000 is reported to be able to access all Microsoft-specific filesystem types, but thats it. TUJNext, you will mount and access other hard drive partitions that are foreign to Linux: In this case you will mount and access the Windows98 partition on your hard drive. Amazing as it seems, Linux can read and even write to a Windows partition without any trouble at all. This is true whether the filesystem is local, or if it is across a network. Admittedly, this wide adaptability is exactly what makes Linux the top choice for hackers, but it is also a huge leap in connectivity for the systems administrator, who would otherwise need a separate partition and reboot to access and fully use each separate operating system on his network. However, since a systems administrator can grant or revoke access to each filesystem in turn (either by user, process, or user group), security is still fully maintained within a Linux-based network.TF;After becoming familiar with manually mounting a filesystem , you will then learn to configure your system to mount these things automatically when you load them. For example, the vast majority of CD-ROMs are formatted in ISO-9660 (Joliet) format. Therefore, why manually mount the CD-ROM drive every time you need to use it, unless you have some exotic or proprietary format on one of your CD-ROMs? Also, you can set your floppy to automatically detect and use whatever type of filesystem that particular floppy has been formatted in. But lets begin with the basics...Th]Remember, you can initially mount/umount systems only as root, so use su to get root access. T iT@Mount a CD-ROM manually. You can do this with one small command:S1APdddA @WW8Num123T1!mount -t iso9660 -r /dev/cdrom /mnt/cdrom The -t option tells the kernel exactly which filetype youre using (ISO 9660, aka the Joliet filesystem), the -r option tells the kernel to mount the device as read-only (you cant write to a simple CD-ROM), the /dev/cdrom tells the kernel which drive to use, and /mnt/cdrom is where you want the reference link to go (that way, you can enter and use the directory /mnt/cdrom when you want to do anything on the CD-ROM... it is the equivalent to /dev/hda, but is set up on a temporary basis. A8)Tw#^Verify a successful mount by entering su mode (using the root password), and then the command A8&(Td/ls /mnt/cdrom Browse through the directories using ls and notice that you can see everything on that CD-ROM (there is no such thing as hidden files in Linux.) If you want to access anything on there, you will have to use the appropriate program to do it. Open and read some of the *.txt files using vi, since text files are universal. If you want to see more than one page of the text in vi, use CTRL-F to go forward one screen, and CTRL-B to go back one screen. Just remember that you cannot write to a file on the CD-ROM, so use the command :q to exit vi. A8A8A8 "TSA PTXMount an MS-DOS FAT-formatted floppy disk. Again, you can do this with only one command:S1APdddA @WW8Num573T!mount -o conv=auto -t msdos /dev/fd0 /mnt/floppy The -o option actually means option...it is a way of letting the kernel know that youre using a special option...and the part -o conv=auto is not really necessary... it is only there to automatically convert all text files on the fly (as they are read) to a Unix format. This will not write anything to the disk, but is a helper, in case you want to print any of these files. Again, the -t option tells the kernel which filesystem youre using on the floppy (in this case FAT16, and Windows98-formatted floppies will usually work with -t vfat if they do not mount in -t msdos. Again, /dev/fd0 is the floppy driver that the kernel will use, and /mnt/floppy is where the link will go.A80A8 MTA8 muT!It is important at this point to tell you that when you access /mnt and have more than one device mounted manually, you will have to further specify which device, by using /mnt/cdrom or mnt/floppy. This is why you have to further specify the devicename when you set the link in /mnt...you can use /mnt alone in your command line, but it will cause confusion later if you try and mount more than one device to it without specifying a devicename, and an error will usually spring up if you try.T!uAgain, look through some of the text files and open them in vi, using the same commands listed in the first exercise.T\Unmount each filesystem in turn. This is far simpler: To unmount the CD-ROM, use the commandS1APdddA @WW8Num463T!umount /dev/cdrom ...thats all there is to it. Similarly, you unmount the floppy with the command umount /dev/floppy ... nothing to it. (Just remember that the command umount is missing the n on purpose.)A8A8cuT0Edit /etc/fstab to allow users mount/umount privileges. This can be accomplished in whole on pages 166-167 of the Running Linux textbook. You will set permissions so that you can mount and umount only the floppy and CD-ROM as a normal user, and not root. Logout and log back in to test the changes as a normal user. Try and mount a hard drive as a normal user, and notice that it cannot be done.

Remove the floppy and switch to Windows 98 (reboot and choose dos at the LILO prompt) and test the disk by reading it in Windows Explorer...you should see an empty disk, but Windows 98 will not read an unformatted floppy. Copy a text file to that floppy, remove the disk, reboot into Linux at the LILO prompt, and if you set automount correctly, you should simply be able to insert the floppy, then use the command ls /mnt/floppy as a normal user (without having to use the su command.) When you have successfully completed this step, remove the floppy and it will automatically unmount itself.S1APdddA @WW8Num43A8eA8ky3T'SAPdddTANext, we will go into su mode (again using the root password) and create a temporary swap file using the command dd if=/dev/zero of=/swap bs=1024 count=8192. This will create a swap file 8MB in size. For a larger swap file, add 1024 bytes to count= for each additional MB of size. Now, format that swap file, using the command mkswap -c /swap 8192, again keeping in mind the size...make sure it matches the swapfile size you specified when you created the file.

These two programs are amazingly easy to use, and yet are flexible and powerful at the same time. The two programs are also universal to nearly all Unix systems in use today, so you can use it on anything from Linux to AIX to Solaris, without having to re-learn their use entirely. TrgTar and gzip are the workhorses when it comes to upgrading programs, especially programs downloaded from the Internet. They are very similar to the old PKZIP program, except that they are more flexible, and do not require as much accommodation. You will find that once you have a basic grasp of the tar and gzip commands, the rest will come easy. As with any other program in Linux, you can pipe the results into almost anything, and can use the command line to create a flexible method of making your compressions and backups do almost anything you want them to.

Simply hit one line at a time to use the defaults for the next few questions, until you see a notice telling you that the kernel config is finished. You will still have lots of drivers in there that will not run on your system, but the point is to 1) show you that you can manage and trim down your kernel by an almost infinite degree, unlike Microsofts Windows series of operating systems, and 2) That you must be rather familiar with your machine to know exactly which card chipsets and items you do have. When in doubt, always answer ? and read the help file on that question...in some cases, you might need it, in others, you might not. Still in others, you will receive information on any additional items you may have to enable later on to enable the option you just selected. TNext, you need to run make dep. Wait for the command prompt to reappear. Make sure youre not running anything else at this point (you shouldnt be), then run make bzImage (the kernel in this exercise will be too large for a standard make zImage, but the change will not affect the operation of the kernel. Note that the make bzImage command can only be used on newer machines.) when this is complete, go to /bootS1AP6dddQA @WW8Num38A8A83T Next, cd /usr/src/linux/arch/i386/boot/ Then run rdev to make sure that the kernel boot partition is listed as being the same device that was originally there (in this case /dev/hda2.)S1AP6dddQA @WW8Num38A8'3 T?Now, copy the new bzImage to /boot with cp bzImage /boot (make sure that you do not get an overwrite file? error message - if you do, answer n, change directory into /boot and rename bzImage there to bzImage.old. This should not happen in your installation, since you have not compiled the kernel before now. ) S1AP6dddQA @WW8Num38A8(83 Ta Fire up the vi editor for lilo.conf ( vi /etc/lilo.conf ) and change the image = to reflect /boot/bzImage (make very sure you pay attention to the case sensitivity.) Once you have edited lilo.conf, run /sbin/lilo to reflect these changes in LILO itself. S1AP6dddQA @WW8Num38A8'9A83 TNow comes the last and most exciting part: Reboot the system and make sure it reboots correctly. Have your boot disk (made in Lab 3) ready just in case.TSA PT'SAP6dddQT_ 'If something goes wrong at this point: SAd A 3T'SAP6ddd6TIf nothing happens, or the kernel panics during boot (that is, it wont start at all and loops endlessly or locks up), shutdown the machine with the power switch. Use your boot floppy to reboot the system, and re-edit /etc/lilo.conf on the hard drive to reflect the old kernel. Then go through the steps once again to rebuild the kernel completely. If the second rebuild still doesnt do it, you may have to re-install the whole system.TIf you see some error messages during boot relating to System.map, you will have to make the update manually: Once you have rebooted completely, go to su mode, then cd /boot . Change the name of System.map to System.old . Once this is done, use the following command and drag out the new System.map and put it into place: cp /usr/src/linux/System.map /boot You will be asked if you want to overwrite the present System.map in /boot...answer y and the new .map file will be moved in. Reboot again to insure that the new map no longer produces any System.map-related errors. The system map, during boot, lets the kernel know where everything is in a basic system.A8DgTIf you see an error during boot concerning module dependencies, you will have to manually build and set these dependencies. Create a directory known as /lib/modules//T Tjcopy the module.dep file from the old /lib/modules/ to the directory you have just created. You will notice that this will erase the old directory. Once the file is copied, go to the new /lib/modules/ directory and issue the command depmod -a . Once this is done, reboot the system and the error should be gone. This error refers to a lack of module dependencies (you shouldnt have any modules loaded), because the kernel looks for these dependencies during boot time. Modules are explained further in Chapter 7 of the Running Linux textbook under Loadable Device Drivers. A8A8 2?T\ Lab 7: Managing system logsS(A PAd A @3T T=2Materials: None - they are already on your system.TpStart your machine and log in as your usual account. You will need to log in as su to perform many of the next steps, so it is safe to do so and remain as su during the entire lab. The system logs require root login specifically because this prevents anyone without root access from changing the log to hide any activities they might have performed without permission.S1AP6dddQA @WW8Num373T6Type vi /var/log/syslog.conf and notice that you have more than one log present...this is where you can also add or remove the items that you want to see logged. Since were not going to change anything here, you can get out of vi at any time by typing :q , which will quit vi without making any changes to it.S1AP6dddQA @WW8Num37A83T"Change to the directory /var/log. Then peek at the messages log using vi messages . Use the pageup/pagedown buttons to scroll through the various shutdown and startup messages - you can see from this log that messages contains all notices and messages sent to or from the kernel for the past few days, even longer. You will notice -MARK- listed every 20 minutes, if your machine has truly sit at idle, say, overnight. You can tell when your system was restarted by the simple message: syslogd 1.3.3: restart The very first thing that init starts (after the kernel starts it) is the system logs - this is to provide all diagnostics information you might need in case things go wrong. You will also notice that there is a whole lot more listed than what you had seen during boot, in addition to all boot messages that you have seen on the console during startup. Finally, you will notice the exact time in which you gained su access, and whether it was successful or not (though it obviously must have been successful for you to access the log, the log also records unsuccessful attempts as well. This comes in handy when checking for hacking attempts, since hackers need root access in order to actually do anything on your system.)S1AP6dddQA @WW8Num37A8 3T8Back out of vi (:q) , create a directory called /oldlogs, and archive your old messages log by the command: cp /var/log/messages /oldlogs/messages.1 Now, get rid of the current logs contents with the command: cp /dev/null to /var/log/messages ...when asked if you want to overwrite the file, say y . This will literally remove the log messages and get the file ready to receive more entries. It does this by overwriting the doomed log file with a new file of 0 bytes.S1AP6dddQA @WW8Num37A8mA83T}Now, back out of su mode, then try to go back into su mode with a bad password. Then logoff, and log in as root, but use a bad password again. Now, log on with the correct normal username and password, then use vi to open /var/log/messages again. Notice that all the previous entries had been erased from the current log back when you copied /dev/null to it. However, you will notice that your failed attempts to login as su and as root are recorded. If you notice a large number of failed logon attempts into root or su, then it certainly warrants further investigation, since this is an obvious sign of a brute-force break-in attempt. S1AP6dddQA @WW8Num373T4S)AP6dddQA  @TOnce you have updated your logs, you may notice that the old logs are no longer needed or used by the system itself. From here, you can either keep the old logs in the folder /oldlog (or any other name you may choose to create), or you can let it sit on your hard drive for, say, a month, then move them wholesale to a backup device, be it a tape, CD-R, or whatever you use to backup your system. This will free up space that can be used by other logs that have been outdated, or by anything else. As a practical rule, backing up your logs this way (all of the logs) once per week is the best method, depending on how busy the machine in question is. S1AP6dddQA @WW8Num373TB)Finally, know that you can automate this log update routine through crond or anacrond, simply by having cron refer to a script that combines these commands for you. Scripting is covered in deeper detail in Scheduling Jobs Using cron, earlier in Chapter 8 - Use this section to create a simple script that will do exactly this for you, and to compress the log files for you as well - show the instructor your results: Prove the script by having it run once within 10 minutes of setting crontab. The example on page 239 is an excellent place to start.SA PT7Lab 8: The Line Printer DaemonSA PT [Materials Needed: A small Linux-compatible printer (HP DeskJet) provided by the instructorS(Ad A A @3TN'A Bi-directional printer parallel cableSAPdddTkDThe power supply for the printer, as well as paper and etc. materialSAPdddTynThis lab will help you through what most people consider to be the toughest part of running a Unix system - the lpd or Line Printer Daemon. In reality, Linux has made the job much easier, though you may find that there are more helper tools installed in Linux than there are the fully flexible tools one would find in other flavors of Unix, such as Unix V or AIX. T'First: Before you do anything, shutdown your machine entirely, and turn the power off. Plug in the printer, and make sure it comes online. Make sure there is paper in the tray, and that the printer cycles through its normal power-up sequence. Once you are satisfied, turn the computer on, and pay close attention to the boot messages - youre looking for a successful startup of the lpd, what port it is using, and you may even see the specific type of printer the kernel has detected. If you miss anything, you can always use vi to open /var/log/messages and look through the boot process more carefully. Take special note to see if your printer was detected (or started) on lp0 or lp1 ( lp# = Line, Parallel 0 /1. Serial printers will hook up on s0 or s1, otherwise known as Serial (line) 0/1)TiPBefore you configure: Give your printer a quick self-test by the simple command:A8 T5lptest > /dev/lp0SA A @TIf you see text come out of the printer, then you can be rest assured that your hardware works perfectly. If not, inform your instructor.T'SAP6ddd6TGo into su mode. Check the /var/spool/lpd directory to make sure you have a subdirectory listing a printer within it (usually a short name like dj or lp.) if it does not exist, then make note of it for now. Next, open /etc/printcap with vi - look at the following field: sd= (or lp.) This line defines where the spool directory will be for this printer - take careful note of the full path name to that file. Make sure that the field lp=/dev/lp0 matches the printer port you had found and checked for during boot. Next, back out of vi (:q) and make sure printcap is owned only by root, but is read-only to everyone else, with the following commands:S1AP6dddA @WW8Num20A8!#3Tachown root /etc/printcapS>AP6dddQA A @A  @T`chmod 644 /etc/printcapS>AP6dddQA A @A  @T4S)AP6dddQA  @T(If it doesnt exist, create the subdirectory for the print spool - replace lp with whatever name is given in the sd= field of /etc/printcap...the path listed below is only an example, and the proper filters may be elsewhere:S1AP6dddQA @WW8Num443TTmkdir /var/spool/lpd/lp S1AP6ddd6A A @Tr6 chown root.daemon /var/spool/lpd /var/spool/lpd/lpS1AP6ddd6A A @Tv6 chmod ug=rwx,o=rx /var/spool/lpd /var/spool/lpd/lp S'AP6dddQA @A85T'SAP6ddd6TaThe default filter installed during your initial install should work for your system.

You will turn your standalone computer into a server that can be accessed by a Windows NT machine, and in turn allow you to access the same NT machines. You will find a large number of options and configuration varieties, but you will find that once properly set up, the system will run much easier than you think.

Make sure you activate this by removing the ; symbol at the beginning of the line.T TUnder the printer options, you will not have a printer attached, so it would make more sense to not use them - simply put a # symbol at the front of the two printer option lines.
