Your understanding of system administration tasks
is directly related to your ability to use the
information in the manuals.
You should understand the entire manual arrangement;
however, as a system administrator, you will be specially
concerned with the sections dealing with:
The System Calls section defines system
calls (entries into the UNIX kernel). These are functions
used from C programs and permit several system administration
capabilities and privileges directly from locally developed
programs. Some of the functions in this section are:
open, close, fork, execv, setuid, malloc, lock, getpwuid, etc.
The Special Files section describes special
device files, related device driver functions, and networking
support. Although the entries as specified by various manufacturers
are similar, the information provided is system-specific.
The information in this section describes the device
drivers for:
- terminals,
- tape drives,
- hard and flexible disk drives,
- printers, and
- various other hardware.
The File Formats section describes system
file formats and how the system files are used. The files
described include assembler and link editor output, system
accounting, file system dump, configuration, network and
hardware data base formats.
In this section you can find the format for such files as:
a.out, core, dir, fs,
/etc/passwd, tar, cpio,
/etc/ttys, /etc/termcap, etc.
/etc/inittab, /etc/terminfo, etc.
The System Administration/Maintenance section
describes commands for system power-up and shutdown,
commands for mounting and unmounting file systems,
commands for creating special device files, and
commands for creating file systems.
As a system administrator, you will often be
referring to this section, at least in the beginning.
Your understanding of UNIX documentation is essential
for successful system administration, and CTI tutorials
will help in achieving this.
UNIX Systems from different manufacturers have different
device names and different file system (partition) names.
In the ensuing discussion the device names used most often
refer to those on the:
IBM PC/AT - UNIX System V.
AT&T 3B2 and NCR Tower, both under System V, Rel. 3.0.
Sun Workstation and DEC VAX with 4.3 BSD
Of course, you need to determine the correct device names for
your system.
The presentation itself is based on the:
UNIX System V, Rel. 2.1 and 3.0.
UNIX System V, V/2.1.
Berkeley UNIX 4.3 BSD.
If you are running an older version of UNIX, some
commands may not be on your system; however, a great
majority of the concepts and commands presented are
applicable, and you will be able to use them once you
upgrade to a newer version of UNIX.
The system administrator's prompt
on all the UNIX Systems is:
#.
