Here's a complete guide to the Internet's Domain Name System (DNS) and the Berkeley Internet Name Domain (BIND) software, the UNIX implementation of DNS. DNS is the system that translates hostnames into Internet addresses. Until BIND was developed, name translation was based on a "host table"--if you were on the Internet, you got a table that listed all the systems connected to the Net and their addresses. As the Internet grew, host tables became unworkable. DNS is a distributed database that solves the same problem effectively, allowing the Net to grow without constraints. Rather than having a central table that gets distributed to every system on the Net, it allows local administrators to assign their own hostnames and addresses, and install these names in a local database. This database is automatically distributed to other systems as names are needed.
In addition to covering the basic motivation behind DNS, and how to set up the BIND software, this book covers many more advanced topics: how to become a "parent" (i.e., "delegate" the ability to assign names to someone else); how to use DNS to set up mail forwarding correctly; debugging and trouble-shooting; and programming. Assumes a basic knowledge of system administration and network management.
Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The insects featured on the cover of DNS and BIND are grasshoppers. Grasshoppers are found all over the globe. Of over 5000 species, 100 different grasshopper species are found in North America. Grasshoppers are greenish-brown, and range in length from a half inch to four inches, with wingspans of up to six inches. Their bodies are divided into three sections: the head, thorax, and abdomen, with three pairs of legs and two pairs of wings.
Male grasshoppers use their hind legs and forewings to produce a "chirping" sound. Their hind legs have a ridge of small pegs which are rubbed across a hardened vein in the forewing, causing an audible vibration much like a bow being drawn across a string.
Grasshoppers are major crop pests, particularly when they collect into swarms. A single grasshopper can consume 30 mg of food a day. In collections of 50 or more grasshoppers per square yard (a density often reached during grasshopper outbreaks) grasshoppers consume as much as a cow would, per acre. In addition to consuming foliage, grasshoppers attack plants at vulnerable points and cause the stems to break off. UNIX and its attendant programs can be unruly beasts. Nutshell Handbooks(R) help you tame them.
Edie Freedman designed this cover and the entire UNIX bestiary that appears on other Nutshell Handbooks. The beasts themselves are adapted from 19th-century engravings from the Dover Pictorial Archive. The cover layout was produced with QuarkXPress 3.1 using the ITC Garamond font.
The inside layout was formatted in sqtroff by Lenny Muellner and Kismet McDonough using ITC Garamond Light and ITC Garamond Book fonts, and was designed by Edie Freedman. The figures were created in Aldus Freehand 3.1 by Chris Reilley.
Very good to cover the basics. I expect the latest book would cover new technologies, but DNS at it's roots hasn't changes and whenever I run into some weird settings on older servers, this book is a handy reference to get it fixed quickly.
