Linux Network Administrator's Guide, 2nd Edition 121

Posted by timothy from the like-tinker-toys dept.
Dan Clough writes "I read this book to improve my knowledge of Linux networking, and in that regard it was a huge success! It was also an enjoyable and easy-to-read book. I am pretty much a Linux beginner, and know 'enough to be dangerous.' My existing home LAN consists of 5 machines: one running Mandrake Linux 9.1, one RedHat 9 (laptop), two Windows XP, and one Windows 98. These are connected to a commercial (Siemens Speedstream) router/switch and share internet access via a cable modem. All the computers can communicate with each other and share files, using Samba. The router also functions as a print-server for a laser printer, which the Linux machines print to via CUPS." Whether your network is bigger, smaller, or hypothetical, Dan's review (below) suggests that O'Reilly's Linux Network Administrator's Guide, 2nd Edition would be useful to have at hand as you build or troubleshoot. Read on for the rest.

summary How to get your machines talking amongst themselves.

This book cleared up many questions I had, enabling my home network to run more efficiently and securely. For example, I learned about many options that can be adjusted in the kernel configuration to allow building a customized kernel which is optimized for your system and needs. This took me one step closer to being ready for my first attempt at compiling my own kernel. I also learned about and implemented some changes to my DNS configuration (improvements to /etc/hosts and /etc/resolv.conf), which resulted in faster name resolutions for web browsers and file managers. I found the information to be detailed enough so that I got what I needed, but not so overwhelming as to turn off my interest level. Another positive note was that the descriptions and examples given throughout the book are "distribution-neutral." I'm using Mandrake 9.1 and RedHat 9, and the configuration file instructions matched up perfectly with both filesystem structures. I believe they would also apply directly to other mainstream distributions, or be easily adapted to slightly different locations.

The book covers some history of networking, and explains the TCP/IP protocol in great detail. Issues covered include IP addressing/subnetting, name resolution, routing, kernel considerations, and drivers. The next several chapters discuss how to configure many kinds of networking hardware and software, such as ethernet, serial/SLIP/PPP, and NIS/NFS. There were great examples of the configuration files that require editing, with understandable explanations of why you were doing it. A make-believe small business is used as an example throughout the book, as they build and expand their corporate network and integrate with other branches of the company.

The next section covered how to set up a firewall/router, again with great example configuration files and scripts. This part went into just the right amount of detail, and included discussion on packet filtering, firewall testing, IP packet accounting, and NAT/masquerading. I'd say I got the most amount of useful knowledge from this section, and will refer to it many times again when I get around to building a router for the home LAN. I now feel that I have enough knowledge to replace my LAN's commercial router with an older computer I have laying around, running Linux with a customized iptables firewall. The IP/packet logging and accounting procedures I now understand will make me feel much more comfortable with what's going on in my network, and the security issues involving the internet interface.

There are several chapters dedicated to setting up and understanding various network services that you may with to install and administer. These include email server/client, UUCP/Usenet news, NNTP and INN, and DNS. There are excellent diagrams, tables, and examples throughout the book. If there was one area I would have liked to have seen addressed (maybe in the next edition?), it would be to have at least an introductory chapter addressing the use of Samba, as it is a common, easy method of integrating a Linux network with Windows computers. Overall I was very pleased with the book, and would recommend it to anyone interested in Linux networking. It has something for everyone, at all skill levels. The table of contents and index are excellent, and you can find exactly what you're looking for very quickly. Additionally, the book offers an excellent list of other reference books, websites, newsgroups, and user groups to assist with getting more in-depth information. I'd like to extend a "well done" to the authors, and to O'Reilly Publishing!

      negatives?

      The reviewer didn't have the slightest grasp of how to setup a network or linux correctly in the first place. This may be seen as a troll or flaimbait, but it is in fact pretty honest. Anyone who doesn't know how to compile a kernel or setup a basic IP Table NAT really shouldn't be reviewing a book.

      The book was designed for the person who did the review, but that doesn't really give a good "REView". It simply says "yeah I read this and learned a whole lot from it". Someone seasoned in linux and networking might have been able to read more into the complexity of the IPTables and whether or not certain applications like Snort and TripWire were designed to also help out.

      Nope you didn't get that because the reviewer actually admitted that they knew absolutely nothing over the basics before they started reading the book, so you probably won't find anything "bad" from the reviewer because they don't know what they're looking for.

        Then, you piss and moan that Linux doesn't have more acceptability. Hey, I hate M$ as much as the next guy (see, I even used the $ instead of the S, to show what a great anti-M$ guy I am), but they have done something the Linux folks haven't: Released a product that my grandmother can sit down in front of, click a few things, and go. If I hand my mother an XP disk and a new computer and say, 'Install this,' she will first tell me to wash my hands, dinner is almost ready; then she will be able to sit down and do it. If I hand her a Mandrake disk, I guarantee, she will need to ask me a bunch of questions about the process, ones that you and I will roll our eyes at, but if you don't know something, you don't know it, and have to find out somehow.

        In short, I haven't read this book. But a beginner's guide reviewed by a beginner means a hell of a lot more to me than the same guide reviewed by someone who is so experienced that he has forgotten his first dull stare at the blinking login prompt.

      Many people would disagree with you here. Just installing Linux on a computer isn't some magic pill that will solve your firewall nightmare.

      Running a dedicated SlipStream router has many advantages over a linux router: It's simple, easy to maintain, and is (hopefully) effective out of the box.

      Running a firewall on top of a full fledged OS can add alot of overhead and unnecessary packaging, and can be very (human) error prone. For instance, his SlipStream box does not have CVS or CC installed, so there's no chance of a hacker compiling odd tools on his router.

      You're right you know "enough to be dangerous" as in getting some worm and unknowingly using your computer as the host of a DDoS attack.

    Generally, no matter what topic in the book, all you get is a simple walkthrough of the commands and minimal description of why you do them or what to do for an unusual set-up. Well, ok, I understand it is "survey type" book, but since all this stuff is readily available via man pages, How-Tos and newsgroups, why buy a 40 dollar book on it?

    For example, getting an ethernet adapter configured via the command line was easy to do, but hard to follow in the book as to why you use certain commands and flags and what things other than the simple example they are good for. I didn't get a great explanation as to theifconfig command and the route command. Also, it was difficult to understand how to configure two ethernet adapters on the same machine in order to set up a Linux firewall or DHCP server in place of a router.

    The section on DNS is a big waste of time. If you are going to delve into DNS, you might as well get O'Reilly's DNS & Bind and slog through that nightmare (not the book, setting up DNS). If all you are doing is setting up 5 machines behind a home router (my set-up is similar), then just use the /etc/hosts file and be done with it. Do you really need a DNS server for that? And if you REALLY need critical DNS, do you want to use a "survey book" to set-up the configuration! Please! The hosts file is about the extent this book should go with DNS as far as I'm concerned.

    I'd say the same for setting up a mail server... with all I hear about sendmail, why would I count on the simplistic outline in a general Linux networking book for configuring sendmail? Especially with the chance of screwing it up and having all hell break loose with the mail server and my network!

    It is not a worthless book. It does a good job of explaining how the internet works, how you set-up a machine to be on the internet and what general security issues are involved (i.e., enough for some clown like me to keep his network safe behind a home router or even behind linux router if you slog through setting that up).

    I won't pretend to be a professional IT guy. But I do like playing around with home networking using various services for fun, so when I buy a book like this, I'd like it to contain more than just simple examples and a rehash of readily available stuff from man pages and How-Tos.

  • Of the more than 30 ORA books I have this is the worst; you'll get far more use out of TCP/IP Network Administration by Craig Hunt (with occasional reference to DNS and Bind for more detail). I'd avoid the O'Reilly book "Running Linux" too. These two books have nothing you can't get a better, more detailed and clearer version of from the web. I use the "Sed & Awk" book more than these two combined.

    I now feel that I have enough knowledge to replace my LAN's commercial router with an older computer I have laying around, running Linux with a customized iptables firewall.

    That's kinda funny. I just went the opposite direction a few weeks ago -- had an old P-200 as my firewall, but I sprung a whopping $9.99 for a D-Link router/firewall. Why? There are a few reasons. One less machine to maintain (I have enough machines already, thank you). One less machine drawing power (yeah, electricity is included in my rent for now, but one day I'll be out on my own, so I should start getting used to downsizing now). One less machine to drain the UPS when power goes out (ugh... you'd think Niagara Mohawk would have their act together after, what, a hundred years of being in the business?).

    The D-Link does everything I need it to, is stable, quiet, always on... having a dedicated computer was fun, but this is a better solution for me.
