All of the operations considered in this article are operations upon a router, whether that router is a Linux box or Cisco dedicated hardware or some other type of machine. In this chapter I consider the traditional methods of IPv4 routing as using static configurations that are manually input by the network administrator. 1.1 Traditional [...]

Grep is by far the most popular command that exists in Unix. Though some may argue about that, but once you begin using grep, it would always be present in all your complex commands that you think of executing at the shell prompt. grep stands for ‘global regular expression printer‘ .

In RegEdit, navigate to the branch or sub-branch that contains your functionality. It doesn’t matter how deeply buried the key(s) are that contain your features; just that you select only your own changes. It might be necessary to analyze the registry before and after you make your changes to figure out which Registry keys are [...]

Although a PC used for writing doesn’t need to be a high-performance computer, its performance can be improved by a good partitioning scheme. The biggest boost comes from my Paging partition on drive H, which is found on my second physical disk. I use this partition to boost performance in the following ways: Move the [...]

If you are looking for a way to speed up your PHP pages on Apache, this is the software you want to install. Huge performance gains can be had when using this software to precompile and cache your PHP pages, and it is very simple to install.

This is an introductory guide for people learning to use a Linux system. It focuses on command-line usage. This is not because everyone will be doing everything at the command line. On the contrary, there are many useful GUI tools and programs in Linux, and some people will be content to stay with these. However, in contrast to GUI programs, which can be learned largely by “click and try”, the command-line requires some deliberate learning, and reading documentation. The benefit of this investment is that you will learn the tools and tricks of the command line which are in many cases faster, more powerful, and more flexible than any GUI program.

As a system administrator, part of your daily duties is to monitor systems for performance and to tune systems where necessary. While there are expensive software products and benchmarking tools that can hone a machine to optimum efficiency, there exist several basic tools within Linux® that permit the knowledgeable system administrator to gather information and [...]

There are at least 2 ways you can set your PHP include_path. Edit your /etc/php.ini file. Inside that file is a directive section for “Paths and Directories.” By default it is set to “.:/usr/local/lib/php”. You can change that value to whatever you like or add to (or eliminate) the default like this: include_path = .:/usr/local/lib/php:./include [...]

Version control is the art of managing changes to information. It has long been a critical tool for programmers, who typically spend their time making small changes to software and then undoing those changes the next day. But the usefulness of version control software extends far beyond the bounds of the software development world. Anywhere you can find people using computers to manage information that changes often, there is room for version control

Subversion depends on a number of third party tools and libraries.Some of them are only required to run a Subversion server; others are necessary just for a Subversion client. This section explains what other tools and libraries will be required so that Subversion can be built with the set of features you want

This says that we have NFS versions 2 and 3, rpc.statd version 1, network lock manager (the service name for rpc.lockd) versions 1, 3, and 4. There are also different service listings depending on whether NFS is travelling over TCP or UDP. Linux systems use UDP by default unless TCP is explicitly requested; however other OSes such as Solaris default to TCP.

The file command is provided by the package sys-apps/file, so if you don’t already have it installed, you’ll need to type emerge file. Chances are you’ve already got it on your system though. To use file simply type file filename and you’ll see information about the filename you passed in. Simple right?

The “Three-Finger-Salute” or, the key combination Ctrl+Alt+Del is typically mapped to the command /sbin/shutdown -r now. In other words, it reboots your system. Sometimes this may be unwanted behavior, so this tip shows you how to disable, or remap that key combination.
