Editorial Reviews

Explains how to administer a network running the AIX operating system on IBM processors. Where appropriate, all three AIX system management interface tool (SMIT), web-based system manager, and command line options are presented. The guide begins with the procedures for system installation and network configuration. Later chapters address file systems, Linux affinity, e-mail, web servers, user account management, security, the backup utilities, clustering techniques, and the enterprise storage server.
