Linux Network Administrator's Guide (2nd Edition)

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
