Linux Power Tools

Dan Clough writes "I found Linux Power Tools to be a useful book, although it does have some shortcomings. It's a 644-page, well-written book that covers almost all aspects of managing, administering, and optimizing a working Linux system. The book's cover claims the target audience as intermediate to advanced users, but I think that beginner to intermediate would be more accurate. More advanced users may find Linux Power Tools a little beneath their level." Read on for the rest of Dan's review. Linux Power Tools author Roderick W. Smith pages 644 publisher Sybex rating 8 of 10 reviewer Dan Clough ISBN 0782142265 summary Well-written introductory and intermediate material; a useful jumping off point for many tasks though not the definitive source for specialized ones.

The text doesn't cover installing a Linux system, but does point out some of the differences among the major distributions in common use today, specifically Debian, Mandrake, RedHat, Slackware, and SUSE. Much of the distro-specific information is contained in a chapter on package management (RPM, deb, tar.gz, and the GUI tools for the aforementioned distros). I found this book a good reference for a new user (and especially someone self-administering their Linux box for the first time), but most "expert" users will not find much here that they don't already know.

The author covers a wide range of software that is frequently used. This includes the major desktop environments KDE and Gnome (with a brief discussion of alternate window and file managers which can be used to create your own custom environment), and office application suites (fairly simple overviews of OpenOffice.org, KOffice, and Gnome Office). Also covered are the two most common bootloaders (LILO and GRUB), printer configuration options (LPRng and CUPS), and a pretty basic section on command-line shells and scripting. There are a couple of chapters that touch on the basics of doing backups (using tar), and some general methods of improving the security of a Linux system (such as using proper passwords and stopping unnecessary services). These topics are followed up by several sections on basic networking configuration (TCP/IP, DHCP, and DNS), and controlling network access with firewalls, TCP wrappers, and xinetd service restrictions.

The last few chapters cover setup and operation of various common server applications, including Apache, FTP, Sendmail, Postfix, SSH, and VNC. All of these server descriptions are of the "general overview" variety, and additional resources will be required by someone trying to configure them for the first time. The book includes a basic glossary aimed at beginners, and an excellent index. The inside front and back covers contain a nice list of essential Linux configuration files, with their default locations, although distro-specific variations are not included.

The two sections that I found the most useful are the kernel customization chapter, and the one on optimizing the X Window System configuration.

Although the kernel chapter contains information that can be found elsewhere, it offers a very understandable explanation, and should make the process of compiling a custom kernel (for performance optimization) achievable for someone who hasn't done it before. In short, everything I needed to know about was right there in one place, and eliminated the need to bounce back and forth between the numerous how-to documents available online. By following this book's guidelines, I was able to successfully compile a kernel optimized for my AthlonXP CPU, containing only the drivers I need, which resulted in noticeable improvements in bootup time, application loading times, and desktop responsiveness.

In the X Window System chapter, the use of options in the XF86Config(-4) config file was well explained, including how to set custom modelines useful for a non-standard screen resolution and/or refresh rate. Font configuration was very clearly discussed, and included directions for adding additional fonts, and enabling smoothing (anti-aliasing) in applications.

Linux Power Tools is an excellent reference book, well suited to assisting in specific tasks related to Linux system administration. There is no real new information here, but this book does better than most at having many things you want to know very accessible in one reference volume. I would compare it favorably with another of my favorite books -- O'Reilly's Running Linux. In fact I've found it to be even more valuable for some specific tasks. It is very complete and recent (copyright 2003), and I highly recommend it to other intermediate level system administrators.

I'd pay good money for a book

[hey!]

That went through all the details of implementing single sign on for a variety of operating systems and applications using Linux and LDAP. In principle I know it can be done, I just don't have the time or the staff to dedicate the weeks it would take to track all the details down. I've gone so far as to get PAM and LDAP working together, the problem is I need to delegate this to people who need a better user interface than editing LDIF files and using ldapsearch.

I've never got to the point of figuring out delegation and scalability because I can't roll out something without a decent user interface for nontechnical folks. Much less got to the figuring out what best practies would be.
