Performing System Management Tasks

Chapter 8  Allowing Access to the System 

An important part of your job as system manager is to choose how to
organize the information on your computer system.  Traditionally, MPE
systems used accounts, groups and users to structure and allow access to
information.

As of release 4.5 of the operating system, MPE/iX implements features of
POSIX, the IEEE portable operating system interface standard.  One such
feature is the Hierarchical File System, or HFS, which organizes
accounts, groups and users under a single root directory and allows the
creation of additional directories to implement a multi-level file
system.  This chapter explains the Hierarchical File System and other
features of POSIX that you need to know to organize and allow access to
the information on your computer system.  It also gives you information
on the following topics:

   *   creating accounts, groups, and users

   *   creating and working with directories

   *   changing passwords

   *   assigning capabilities, user IDs and group IDs

   *   limiting accounts and groups

   *   setting file space limit for the HPSPOOL account

   *   specifying file access permissions

   *   securing disk files

   *   changing security defaults
