C. RedHat Certified Engineer Certification Cross-Reference</A>
</H1>

<P>
<A NAME="chap:rhce"></A><A NAME="chap:redhat"></A>RedHat has encouraged a larger number of overlapping courses, some of which
contain lighter and more accessible material. They concentrate somewhat on RedHat
specific issues that are not always applicable to other distributions.
In some areas they expect more knowledge than the LPI, so it is worth
at least reviewing RedHat's requirements for purposes of self-evaluation.
The information contained in this appendix was gathered from discussions
with people who had attended the RedHat courses. This is intended purely
for cross-referencing purposes and is possibly outdated. By no means should it be
taken as definitive. Visit <I><TT><A NAME="tex2html90"
  HREF="http://redhat.com/training/rhce/courses/">http://redhat.com/training/rhce/courses/</A></TT></I>
for the official guide.

<P>
For each objective, the relevant chapter or section from this book
is referenced in parentheses.

C.1 RH020, RH030, RH033, RH120, RH130, and RH133</A>
</H1>

<P>
These courses are <I>beneath</I> the scope of this book: They cover
L<SMALL>INUX</SMALL> from a user and desktop perspective. Although
they include administrative tasks, they keep away from
technicalities. They often prefer graphical configuration programs to
do administrative tasks. One objective of one of these
courses is configuring Gnome panel applets; another is learning
the <TT>
<FONT COLOR="#0000ff">pico</FONT></TT> text editor.

<P>

<H1><A NAME="SECTION005020000000000000000">
C.2 RH300</A>
</H1>

<P>
This certification seems to be for administrators of non-L<SMALL>INUX</SMALL>
systems who want to extend their knowledge. The requirements
below lean toward understanding available L<SMALL>INUX</SMALL> alternatives and
features, rather than expecting the user to actually configure
anything complicated. Note that I abbreviate the RedHat Installation
Guide(s) as RHIG. This refers to the install help in the installation
program itself or, for RedHat 6.2 systems, the HTML installation
guide on the CD. It also refers to the more comprehensive online documentation
at <I><TT><A NAME="tex2html91"
