The main problems you may encounter (Web site traffic) with initare
The main problems you may encounter with initare services(programs that run in the background) that fail to start properly, as is indicated by the[FAILED]status shown during the boot process. Many of these services don tkeep you from logging in and using your system. Services usually fail becauseof misconfigurations or unsupported hardware drivers. Sometimes a problemservice takes a long time to start up, so you may need some patience while youwait it out. Once the machine boots up, you can use the techniques describedin Chapter 12 to shut off the problem service if it s being a pain. If the machinecan t boot because of this service, you ll need to access your distribution srescue mode to shut off the service. Rescue mode is covered in the next sec- tion. Entering Rescue ModeHeavy-duty system repair tends to happen in rescuemode, which is a special boot selection that simulates your hard disk in whatis called a RAM disk,holding the files entirely in memory. The benefit of thisdisk is that you can perform necessary system surgery without requiring util- ities that are part of the installed system; everything you need is part of therescue disk. The drawback is that this is a purely command-line interface, and you really have to know your stuff to find your way around. Appendix A contains a list of Linux commands, roadmap to try to help youout. Chapter 20 addresses, among other things, how to fix your boot loadersfrom here if your problem is with the boot loader, and how to track down theerror messages your kernel might have left behind. You may also be able tofind helpful tips by reviewing your distribution s documentation and helpforums. Knoppix is quite popular to use for system rescues because it s a whole dis- tribution on a CD. (For more on Knoppix and live CDs, see Chapter 2.) SeeChapter 20 for more on using Knoppix for things like rescuing broken Linux(and even Windows) systems. Just about every Linux distribution includes a rescue mode. Due to spacerestrictions, I have room to cover entering only Fedora s rescue mode in step- by-step detail, but at the very least, here s a quick reference to how to findthe rescue mode in the distributions covered in this book: Linspire:The CD contains a rescue mode. When the installer starts, useyour arrow keys to select Diagnostics and then press Enter. Fedora:The DVD, or the first installation CD, contains a rescue modethat you can enter by typing linux rescueat the installer s bootprompt. Mandrake:The first CD contains a rescue mode. When the installerstarts, press F1 to access the command prompt, type rescue, and pressEnter. 100Part I:Getting Your Feet Wet
