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. With release 4.5 of the operating system, MPE/iX
enhancements now implement 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 introduces you to 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
