Many visitors to this page might not be aware
of the powerful networking capabilities Linux offers right out of the box,
before being supplemented
by one or more of the management packages described below.
These two pages offer clear explanations
of Linux's basic network features and tools,
along with references to more information on each topic:
A full installation of Linux
has an excellent selection of networking commands and tools.
This document provides a summary introduction to them.
like many contemporary fields of Linux development,
offers several sources of good quality fundamental tools,
and a few small and well-executed applications;
but nothing that yet matches the large commercial products in the field,
such as Enterprise Manager or OpenView.
For a programmer such as myself,
who wants to perform fundamental operations efficiently
from my favorite scripting language,
this situation is quite satisfactory;
more pedestrian users with quite complex networks
might want to wait for the application base to mature.
The primary desire of a network operator
is to be able to efficiently and remotely determine
that status of the network devices he supports.
Several very useful packages are available
to perform these functions under Linux.
Most of them offer Web interfaces,
and some will email or page you when alarms pass a configured threshold.
There are many utilities available for requesting management information
from remote devices that support the SNMP protocol.
There is a query package for every major extensible scripting language,
as well as several that operate from the command line.
I not only describe these packages,
but have developed benchmarks to determine which are the most efficient.
Several packages do not quite fit either of the above categories,
so for the moment I have grouped them into a single category.
Such is the custom of our times.
