Linux Training Resources Website
Information
This
training material was originally written in the year 2000 as part of a set of LPI Exam 101
training materials. The LPI training course at Bromley College was subsequently
discontinued and some of the sections of the notes modified and incorporated
into our one-day System Administration Courses. The remainder of the notes have
now been made publicly available on this website in PDF format.
We hope
you find these notes useful, but please note that in places they apply
specifically to the 2.2 kernel and that the objectives relate to the old LPI 101
syllabus, not the current one. These notes will be updated in due course of
time.
If you are
a beginner please do not be put off by these notes, as they
are rather technical. On the other hand if you are a more experienced Linux user
we hope you find the coverage of these topics refreshingly clear.
