I Loved it!.......2007-03-08

I was very suspicious of this book, because I knew it was available online for download. I thought at first, why not just print it and read it. A friend of mine told me this is something completely different. And he was right. It was worth every penny (cent).

The book is a great introduction to Linux networking theory and practices. Although it's lightweight in size, it makes it up with easy to read high quality content. I think even some experienced sysadmins might find a lot of interesting information inside.

The guide is very well written, with nice and self explaining graphics.

Setting up a SHO Linux Network.......2006-08-23

This is an excellent book to start with if you are considering setting up a Linux network for your home or small office. The intended audience is assumed to have some basic programming skills and understands the priority of network security. If you have never written a make file or know what make is, you might want to start with a more fundamental book; you will struggle understanding the concepts of this book. If you have never used UNIX or Linux, you will be quickly LOST!

It is important to realize that this book is a guide and not a reference. Each chapter covers a major system vital to the Linux operating system. Book(s) are written for each system, yet the author covers enough information to get you started and keep you from being dangerous.

The book also indoctrinates you to the procedures and mindsets of Linux. If a specific tool is not covered in this book, you will know how to search for it, read the configuration man pages, build it, and install it.

My background: Mixed Signal IC Design Engineer (20 years), C/C++, C#, Perl Literate. Converting from Win2K OS to Linux because of corporate directive. I have been a user of UNIX and Windows OS for 25 years, however, I never had to administer a network. I wanted to start up a Linux network at home to act as a Subversion server and a general file server.

Good for Overview and Common Practices.......2006-08-10

This is a good first book to purchase if you're getting into Linux Administration. It focuses more on common practices rather than configurations and how-to's. If you're looking to get an idea of how to build your environment (or make it better), this is a good book to start with, then purchase the specific manuals once you've decided on a course of action.

Printed Professional Quality Book.......2005-03-15

This book fits into the space between the general everything there is to know about Linux books (which give limited space to each subject) and highly specialized books that cover only one application such as Apache or sendmail. It's a niche book intended for people aministering a Linux network. It contains what you need to know to set up a network and keep it up.

This is the third printed edition of this book. This has given time for the original work to be expanded and rewritten to satisfy the needs of readers who down through the years have sent in questions on various subjects.

This book is based on the on-line Linux documentation but bound into a convenient book, cleaned up professional illustrations, better indexing. While it costs a bit, it is probably no more than the cost of the ink cartridge it would take to print it out.

good discussion of DNS and sendmail.......2005-03-08

A good education in how to use the Internet, in the context of a linux network. The authors provide a nice lucid explanation of DNS, as a globally distributed database that underpins the Internet. An entire chapter is allocated to this most crucial of ideas. The sort of thing you should have down pat.

Other network aspects are covered elsewhere in the book. Notably sendmail. The most important configuration ideas and settings are shown.

Though, for an edition printed in February 2005, the book only seems to refer to version 8.12 of sendmail. Whereas 8.13 has already been out for several months, and contains much enhanced Milter capabilities for fighting spam. But perhaps the discussion about 8.12 is simply due to the realities of how long it takes for a book to be published and printed.

A very topical chapter is offered last in the book. On wireless networks. It's a decent synopsis of a hugely popular occurrence. But given the rapid hardware upgrades in this field, and the still evolving wireless standards, you may want to seek out a more extensive text.

The long-overdue second edition of O'Reilly's Linux Network Administrator's Guide, by Olaf Kirch and Terry Dawson, still sports the cowboy colophon, suggesting that netadmins have retained their Lone Ranger personas. While life for a sysadmin has improved over the years with the introduction of the ./Configure utility and build-less rpm distributions, network building and maintenance is still a vast prairie, in its complexity growing faster than the availability of tools and documentation to tame it. Linux document libraries are filled with disparate, obsolete, and/or redundant How-Tos for multiple Ethernet cards, bridging, cable modems, DHCP, Samba, ISDN, DSL, and laptop Ethernet card peculiarities.

Sadly, the recycling of the cowboy motif indicates a deeper problem with the second edition. While authors Kirch and Dawson have expanded and updated Kirch's original text, they give scant attention to any of the paradigm shifts that have occurred in Linux networking since 1993. Strangely, the authors have retained much material on core technologies of diminishing importance in the era of small ISP-connected networks. While PPP and Chat are still relevant for ISP connections, such protocols as UUCP, SLIP, dip, and PLIP are largely of historical interest. Discussions of packet routing are not browsable, and there is no practical presentation of the configuration of routing for multiple Ethernet cards, which the small-network Linux market needs. The showstopper is the absence of any discussion of configuring DHCP, DSL, cable modems, or Samba. When the authors blithely indicate in their preface the growing importance of these areas, one gathers that this book was written in 1997 or earlier.

Still, in the nearly 500 pages of earnest effort, Kirch and Dawson expand on such infrastructural basics as TCP/IP, NIS, and DNS. Discussions of firewalls and IP masquerading are genuinely new, and the authors include an up-to-date section featuring firewall implementations in kernels as recent as 2.4. Such tried-and-true utilities as SMTP and Sendmail are covered in detail, although out-of-the-box implementations haven't posed serious problems for years. The five chapters on reading and serving network news are positively excessive.

Perhaps it's time for the cowboy to come back to the ranch to see how the world has changed. --Peter Leopold

Book Description

Linux, a Unix-compatible operating system that runs on personal computers and larger servers, is valued above all for its networking strengths. The Linux Network Administrator's Guide spells out all the information needed for joining a network, whether it's a simple UUCP connection or a full LAN with a Linux system serving as a firewall, an NFS or NIS file server, and a mail and news hub.

This book, which is one of the most successful to come from the Linux Documentation Project and remains freely distributable under its license, touches on all the essential networking software included with the operating system, plus some hardware considerations. Fully updated, the book now covers firewalls, including the use of ipchains and iptables (netfilter), masquerading, and accounting. Other new topics include Novell (NCP/IPX) support and INN (news administration). Original material on serial connections, UUCP, routing and DNS, mail and News, SLIP and PPP, NFS, and NIS has been thoroughly updated. Kernel options reflect the 2.2 kernel. However, some topics covered in other books (notably Samba and web server administration) are not in this book.

Topics include:

Introduction to TCP/IP
Configuring network and serial hardware
Domain Name Service
Serial line communications using SLIP and PPP
NIS and NFS
Taylor UUCP
Administering electronic mail, including sendmail and Exim
Administering Netnews, including INN and several news readers
Firewalling using ipfwadm, ipchains, and iptables (netfilter)
Masquerading and accounting
IPX configuration for a Novell Netware network

Customer Reviews:

Dirk.......2004-09-22

O'Reilly was first, but there are publishers now beating them at their game. "Linux Network Administrator's Guide" is an OK book. It took the time to introduce me to TCP/IP routing and gateways, but it's one of those books that you have to start several times to get it.

some important topics missing.......2003-11-18

There is some good information in this book but way to much important stuff is missing. Stuff that should be in *any* linux networking book that is missing from this one include:

-discussion of dhcpd, the dynamic host config protocall daemon
-discussion of dhcpcd, the dynamic host config protocol client daemon
-the routed daemon
-any other meaningful discussion of dynamic routing in linux
-any discussion of connectivity with Windows machines (SAMBA is not mentioned anywhere in the entire book)

It would not be possible to administer an actual modern network without any of the above. These omissions are unforgivable in my opinion. Definite one star.

Inconsistincies in user reviews.......2002-01-04

I have not read this book, but want to make a comment about the reviews on this page. Please notice that many people have stated this book did not tell them how to use Linux. It is important to know that the title of the book is NETWORK ADMINISTRATION. Networking is about TCP/IP, FTP and the like. It is not about the file system.

In that light, the negative reviews all came from someone looking for a linux "how to", not a networking guide. The positive reviews came from individuals who knew what this book is about and it met their needs.

Networked yourself.......2001-09-17

One of first book about TCP/IP services configuration. I really found that this book really usefull. However this book only suitable for beginners.

Good, BUT.......2001-08-09

This is a good book BUT it is not perfect. For one, it is way too hard for a beginner. Don't even bother if you're a beginner. Second, it's an oldstyle book too, with a whole chapter on SLIP, IPX, and UUCP, and stressing ipfwdmn (whatever it's spelled) over ipchains. and leaving out stuff like Samba and Xwindows (!!). I don't think Perl is mentioned once.

If you are running a one- or two-system LAN using Linux, you probably only need simple connectivity between your systems. However, if you are setting up a Linux server for your network and its connection to the Internet, you've got a lot of work to do in installation, configuration, and maintenance---and you probably require some assistance. Olaf Kirch wrote Linux Network Administrator's Guide as part of the Linux Documentation Project to cover just such information. Although you can download the book for free, the O'Reilly version of the book looks (better layout and graphics) and feels better than the online version and has a superlative index.

This book details all the tasks associated with e-mail setup and maintenance, news group setup, and essential network applications such as rcp and rlogin. In some cases you may find the level of detail not sufficient to complete the task. In those cases, Kirch tells you where to find more detailed information on the Internet. This methodology has kept the book to a very handy size, which makes it an easy-to-use, versatile resource for anyone managing a Linux network. --Robert Frankland

Book Description

Linux, a UNIX-compatible operating system that runs on personal computers, is a pinnacle within the free software movement. It is based on a kernel developed by Finnish student Linus Torvalds and is distributed on the Net or on low-cost disks, along with a complete set of UNIX libraries, popular free software utilities, and traditional layered products like NFS and the X Window System. Linux is sweeping Europe, winning adherents in North America, and generating enthusiasm worldwide.

Part of Linux's appeal is the unstructured and far-flung manner in which it grew. Self-styled hackers from many countries created it. Maintenance and support are distributed in a similar manner. And even its documentation -- from installation instructions through manual pages and full-length guides -- is the product of a volunteer effort, the Linux Documentation Project.

Networking is a fundamental part of Linux. As a stand-alone computer system it is impressive enough, but sooner or later you, the user, are going to want to send someone a file, mount a file system from another computer, read Usenet news, or search the World Wide Web. Whether you want a simple UUCP connection or a full LAN with NFS and NIS, you are going to have to build a network.

One of the most successful books to come from the Linux Documentation Project is the Linux Network Administrator's Guide by Olaf Kirch. It touches on all the essential networking software included with Linux, plus some hardware considerations. Topics include:

Introduction to TCP/IP
Configuring network and serial hardware
Domain Name Service
Serial line communications using SLIP and PPP
NIS and NFS
Taylor UUCP
Administering electronic mail, including smail and Sendmail+IDA
Administering Netnews, including C News, NNTP, and several news readers

re: needs updating.......1999-09-14

Its actually being rewritten at the moment I believe. But the rewrite has been going on for at least a year that i know of so far. Guess should be out in the not too distant future

Informative but outdated.......1999-03-03

If you need to build a old fashion Linux Server with UUCP, I think it is a great book for you. But if you need to build a web server, Samba or firewall, try to get another one.

Useful.......1998-01-23

This book is denseley packed with essential information. Although it needs to be updated, I give it a high rating because as far I know, there's no other book that focuses on this subject. There are sections that I'll never use, such as "UUCP", but the overall authoritativeness of the volume leads me to believe that those sections are critical to other people in different situations!

A fine work much in need of updating.......1997-10-27

As one of the essential books on the Linux shelf, Kirsch needs to release a fresh version. Networking has changed much in the nearly three year since January 1995. (For instance, there's not a single mention of the administration issues of httpd). In addition, the sendmail section is very much IDA centric...needing more details on setting up sendmail "as is". Also lacking is consistency: some of his examples concern a "virtual brewery" and then there's an unexpected shift to a "Groucho Marx University." These points aside, LNAG does contain sufficient material to be a valuable addition.

The introduction of Linux System Security acknowledges that there's no magic bullet as far as security is concerned. Security-minded system administration is a process of constant revision. It promises, though, that "[i]f you follow the procedures outlined in this book, you will certainly reduce your level of vulnerability." The book delivers on that promise in spades.

Using Red Hat Linux as the demonstration environment, the authors explain how to use a suite of publicly available tools to analyze, protect, and monitor your machines and networks. They approach the subject from a practical standpoint, emphasizing software and its use while referring the reader (using copious bibliographic notes) to more specialized works for detailed information on cryptography, firewall configuration, and other subjects.

Scott Mann and Ellen Mitchell have done excellent work in combining explanations of the "soft" aspects of security management with the particulars of using software. In a typical section, they explain how to acquire, install, and run Crack, a password breaker. First they show how a bad guy would use Crack to get unauthorized access to a machine over a network; then they explore the "white hat" applications of the program as a security tool for preemptively weeding out weak passwords. More detailed coverage goes to tiger and Tripwire, a pair of powerful auditing and monitoring tools. Along with Maximum Linux Security (which covers more offensive and defensive weapons in less detail), this is one of the two best Linux security books you can own. --David Wall

Topics covered: Linux security practices and tools, as demonstrated under Red Hat Linux 5.2 and 6. Software and commands include Pluggable Authentication Modules (PAM), OPIE, syslog, sudo, xinetd, Secure Shell (SSH), Crack, tiger, Tripwire, The Cryptographic File System (TCFS), and ipchains. The authors discuss administrative policies and procedures along the way.

by Scott Mann has advice on starting from scratch when you are setting up a machine to make it secure from attack from the outside.

I like Linux.......2002-12-21

Linux is better than Windows.

By far the best book I've read on Linux security.......2001-01-31

This book is well-written, thorough, and practical rather than academic. I particularly found the chapter on securing network services to be helpful, and was able to identify some potential security problems on the systems I support as a result of information provided in that chapter.

Wow - what a killer book!.......2000-10-01

This book is incredibly thorough, and up to date. For example, Red Hat Linux 7 has just come out, and does now has xinetd as a replacement for inetd. Well, you guessed it, this book has about 27 pages on xinetd!

Want info on ipchains? This book has at least 50 pages on the subject!

I could go on and on about this book it is so good!

This book is written by experienced people, not just an author who was assigned another book to write.

You will not regret buying this book!

Probably the best book on open source security tools.......2000-07-20

Actually all tools described are not Linux specific and can be used for any Unix including FreeBSD and Solaris.

The authors seems to know the subject and really used tools that they are writing about. For several popular tools the book provides some useful info that is difficult to find elsewhere. Pretty decent typography, although it's a little bit too academic and does not use icons on margins that IMHO simplify reading.

As for the classic open security tools, the book covers PAM(36 pages), Sudo(20 pages), TCP Wrappers(24 pages), SSH(55 pages), Tripwire(24 pages), CFS and TCFS (30 pages), and ipchains.

From the first reading it looks like the chapters are *not* a rehash of existing online documentation. In addition to the chapters about classic open source security tools I like chapters about logs: a chapter on syslog (Ch.8) and a chapter on log file management (Ch.17).

Now about weaknesses. The chapter on Tiger is rather weak. Moreover regrettably Tiger is a legacy tool, but actually information is not completely useless -- it's not difficult to switch to another tool after one understands how Tiger works. Actually Perl is superior for writing Unix vulnerability scanners in comparison with shell. May be hardening scripts like Bastille would be a better choice for this chapter in the second edition of the book.

Book is incomplete in a sense that neither Snort (or any similar intrusion detection tool), nor open source network scanners (Saint, Sara, etc.) are covered.

Of course there are some typos, but generally not that many. But what is really bad is that the Prentice Hall book page currently is pretty basic with no errata or additional links. The authors do not provide a WEB site for the book.
