Advanced HP-UX Systems Administration

		(Network management/setup, security issues, performance)

			COURSE DESCRIPTION

	This course will teach the commands and methods needed to setup
	and manage advanced features in an HP-UX / Unix system.  The course will
	also use a problem solving approach in the lab exercises to teach
	system managers the proper application of advanced features.

	Systems: HP-UX versions 11i v1 and v2 on any supported hardware platform 

			COURSE OBJECTIVES

	On completion of this course, a systems administrator should be able
	to implement security features for the system and it's users; enable
	communications via modems; define name service capabilities; and
	use advanced options and setups for the shell command interpreters.
