Linux Network Administration
Essentials
This two day course provides a follow-up to Linux System Administration (Part 1),
for those who wish to network their Linux systems. The course covers
the essential elements of configuring the network connection including
routing, and installing major services such as NFS, NIS and DNS, plus
other services. The SAMBA PC file and printer sharing software will
also
be briefly examined, as will the Apache webserver; working
installations
of both systems will be created. The course uses the Redhat and CentOS
Linux ES distributions.
Our Linux courses are suitable training for Linux LPI or RedHat Certification

INTENSITY: About 40% of the course is
practicals, and 60% lectures
RESOURCE: Each student will have
exclusive use of a fully configured Intel PC for the duration of the
course,. Each student will be provided with a full set of training
notes, and quick reference cards to assist with file editing and Linux
commands. A full reference for Linux resources will also be provided.
PREREQUISITES: Experience of Linux
systems admin similar to the level described in the Linux System Administration (Part 1) course.
FOLLOW UPS: The Linux Advanced System
Administration course would be the ideal follow up for those wishing to
further their skills and prepare for the Linux certification from LPI
or
Redhat. See Linux Advanced Administration Our Linux Utilities and Shell Programming
course is also a must for those concerned with system and network
security. First Alternative also offers an extensive range of Solaris
courses. If you are responsible for looking after day-to day
administration, then we can offer a very comprehensive range of Systems
Administration courses, right up to Solaris Advanced System Administration. Sheets
describing each of our courses, and current schedules, are available on
request.
To complement your Linux knowledge, you may
wish to learn skills for data manipulation, statistical analysis,
web-site interaction, and more. A very powerful and popular
programming/scripting language is available on Linux, known as Perl.
First Alternative offers two Perl courses, Perl Basics and Perl Programming.
PRACTICALS / TAKEAWAYS: Each student
leaves the course with their own set of training notes for the material
covered; around 120 pages per day of training.
| Every student who attends this course
will be issued with a signed certificate of course completion, which we
will be happy to "authenticate" upon future request. |
SOFTWARE VERSIONS: We currently use
CentOS and Redhat Enterprise Server.
