Advanced Unix Systems Administration
(Networking Configuration ,Security Considerations ,Performance Monitoring and Tuning)
HP-UX Training Overview
This course will teach the commands and methods needed to setup
and manage advanced features in a 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
HP-UX Training Prerequisites
It is assumed that the student has experience with interactive Unix
systems with user-level commands, basic shell or Perl scripting
techniques, and essential systems administrator functions.
HP-UX Training Course duration
This course requires five (5) days, approximately 70 % lecture,
and 30 % lab time.
HP-UX Training Course Objectives
On completion of this course, a system manager should be able to
implement networking features for the system and it's users; define
name service capabilities; and use advanced options and setups
for the shell command interpreters.
