In the world of Unix operating systems, the various BSDs come with a long heritage of high-quality software and well-designed solutions, making them a favorite OS of a wide range of users. Among budget-minded users who adopted BSD early on to developers of some of today's largest Internet sites, the popularity of BSD systems continues to grow. If you use the BSD operating system, then you know that the secret of its success is not just in its price tag: practical, reliable, extraordinarily stable and flexible, BSD also offers plenty of fertile ground for creative, time-saving tweaks and tricks, and yes, even the chance to have some fun.
"Fun?" you ask. Perhaps "fun" wasn't covered in the manual that taught you to install BSD and administer it effectively. But BSD Hacks, the latest in O'Reilly's popular Hacks series, offers a unique set of practical tips, tricks, tools--and even fun--for administrators and power users of BSD systems.
BSD Hacks takes a creative approach to saving time and getting more done, with fewer resources. You'll take advantage of the tools and concepts that make the world's top Unix users more productive. Rather than spending hours with a dry technical document learning what switches go with a command, you'll learn concrete, practical uses for that command.
The book begins with hacks to customize the user environment. You'll learn how to be more productive in the command line, timesaving tips for setting user-defaults, how to automate long commands, and save long sessions for later review. Other hacks in the book are grouped in the following areas:
Customizing the User Environment
Dealing with Files and Filesystems
The Boot and Login Environments
Backing Up
Networking Hacks
Securing the System
Going Beyond the Basics
Keeping Up-to-Date
Grokking BSD
If you want more than your average BSD user--you want to explore and experiment, unearth shortcuts, create useful tools, and come up with fun things to try on your own--BSD Hacks is a must-have. This book will turn regular users into power users and system administrators into super system administrators.

Lightred 5 magenta 13 lightmagenta 6 brown 14 yellow 7 white 15 lightwhite - 37 - Gee, that reminds me of my old DOS days when I discovered ansi.sys. Yes, your terminal is capable of color and you're looking at your possible color schemes! (It likely looks much more exciting on your terminal, since it's not in color in this book.) If you see some colors that appeal to you, add them to your terminal. For example, this command will set the foreground color to yellow and the background.
Uppermost directory of the source code to read the INSTALL file. 1.13.3.5 Naming windows ID numbers identify windows pretty well, but I prefer to use names of my own choosing. Change a window's name with the command C-a A. For example, C-a A email, C-a A source, and C-a A doc seem like a big improvement for the currently active windows. Now, listing the active windows with C-a " will show the following: - 66 - NUM NAME 0 source 1 email 2 doc At this point, you have one screen session.
List, even if it is compressed (i.e., its filename ends in either .Z or .gz). If you use the file command on the dwg files, you'll find that each file is ASCII text. Mind you, the contents don't look like the average dictionary file: # head abbr.dwg #!xdawg 02bon2b 04sa7ya 0bbroyg 6bvgw 0egbdf 0fsasya 0gok 0oottfogvh - 156 - 0roygbiv Don't worry, those aren't the actual words. Instead, the numbers sort the words by likelihood. That is, the words don't appear in alphabetical order, but rather.
From at least 3 of these 4 classes, or a 7 character long password containing characters from all the classes. Characters that form a common pattern are discarded by the check. A passphrase should be of at least 3 words, 12 to 40 characters long and contain enough different characters. Alternatively, if noone else can see your terminal now, you can pick this as your password: "inward!smell:Milan". As you can see, the password policy is provided, along with an example of a strong password that.
Hosts in your network or a particular subnet can access certain systems. But, as in any security mechanism that relies on IP addresses, do keep in mind that IP addresses can be spoofed. Finally, if you make changes to this file, test your changes immediately. If you restrict access to certain users, ensure those users can still log in. Further, try to log in as other users to ensure that they are actually being denied access. 3.12.3 /etc/ssh/sshd_config Think for a moment. Other than logins to.
