X Window System Administrator's Guideby Linda Mui
Synopses & Reviews
As X moves out of the hacker's domain and into the "real world," users can't be expected to master all the ins and outs of setting up and administering their own X software. That will increasingly become the domain of system administrators. Even for experienced system administrators, X raises many issues, both because of subtle changes in the standard UNIX way of doing things and because X blurs the boundaries between different platforms. Under X, users can run applications across the network on systems with different resources (including fonts, colors, and screen size). Many of these issues are poorly understood, and the technology for dealing with them is in rapid flux.
This book is the first and only book devoted to the issues of system administration for X and X-based networks, written not just for UNIX system administrators but for anyone faced with the job of administering X (including those running X on stand-alone workstations). The book includes:
Book News Annotation:
Volume 8 of O'Reilly & Associates' excellent series describes the role of systems administration for system administrators with a knowledge of UNIX and some familiarity with system and network administration. Discussion of the user environment and the X Display Manager are followed by a chapter on security (this chapter is a must for all administrators). Discussions of font managers, terminals and color are included. A set of useful appendices describe how to add a host, how to compile public domain software, X on non-UNIX, resources, and error messages.
