Hunt has retained the organization and format of the original version and has updated and expanded the material. The examples utilize both Solaris and Linux, and the BIND and sendmail versions are also current. Hunt describes developments in routing protocols and increases coverage on topics that now warrant separate books, such as Network Security. The first edition included references on gated , named , and sendmail . However, the second edition references reflect the individual software changes and are much more extensive and detailed.
Hunt illustrates each topic thoroughly and precisely.
This is a necessary resource for any and every system administrator. It continues to be among the best books that I have encountered. Training both new and current employees has customarily been an integral part of business. Technologies and procedures change rapidly, and every organization's staff should reflect these changes. The differences among them depend on the level of user input.
