GUI Package Management Tools

The text-mode utilities that underlie all Linux package management tools are very flexible, but they can be intimidating to new administrators. For this reason, several GUI administrative tools also exist. These programs typically serve as front ends to the text-based programs described earlier that is, they call the text-mode programs and interpret the results in a GUI window. Many distributions ship with their own unique GUI package management tools, and it's impossible to cover them all...

Answers to Assessment Test

C. mkfs is a tool for creating a new filesystem, which is something you're likely to need to do in an emergency recovery situation. fdformat does a low-level format on a floppy disk, WordPerfect is a word processor, and traceroute helps diagnose network connectivity problems. You're unlikely to need to use any of these tools from an emergency disk. See Chapter 9 for more information. 2. D. Swap space is being used lightly, and so it isn't degrading system performance. The available swap space...

Peripheral Interface Problems

There are a handful of interfaces used for most peripherals. In addition to the EIDE and SCSI interfaces discussed earlier in this chapter, common interfaces include the following Floppy x86 computers include a floppy interface that can control up to two floppy drives. These interfaces are very mature, so the Linux drivers seldom cause problems. One configuration detail to which you may need to attend is enabling the port in your computer's BIOS setup screen. If this is not enabled, Linux might...

Rundown of Linux Distributions

Within the Linux world, there exist several distributions. A distribution is a compilation of a Linux kernel, startup scripts, configuration files, and critical support software. Distributions also include some type of installation routine so that you can get a working Linux system. Any two distributions may use different versions of any or all of these components, which will produce distinctly different feels. Critical components, though, such as the kernel and certain support software, come...
