|
|
>The <SPAN

CLASS="QUOTE"
|
|

> account is the most privileged account on a
|
|
Unix system. This account gives you the ability to carry out all facets
|
|
of system administration, including adding accounts, changing user
|
|
passwords, examining log files, installing software, etc.</P

|
|
>When using this account it is crucial to be as careful as possible.
|
|
The <SPAN
|
|
CLASS="QUOTE"
|
|
>"root"</SPAN
|
|
> account has no security restrictions imposed upon
|
|
it. This means it is easy to perform administrative duties without
|
|
hassle. However, the system assumes you know what you are doing, and will
|
|
do exactly what you request -- no questions asked. Therefore it is easy,
|
|
with a mistyped command, to wipe out crucial system files.</P

>When you are signed in as, or acting as <SPAN
|
|
CLASS="QUOTE"

>, the

shell prompt displays '#' as the last character (if you are using bash).
|
|
This is to serve as a warning to you of the absolute power of this
|
|
account.</P
|
|
><P
|
|
>The rule of thumb is, never sign in as <SPAN
|
|
CLASS="QUOTE"
|
|
>"root"</SPAN
|
|
> unless
|
|
absolutely necessary. While <SPAN
|
|
CLASS="QUOTE"
|
|
>"root"</SPAN
|
|
>, type commands carefully
|
|
and double-check them before pressing return. Sign off from the
|
|
<SPAN
|
|
CLASS="QUOTE"
|
|
>"root"</SPAN
|
|
> account as soon as you have accomplished the task you
|
|
signed on for. Finally, (as with any account but especially important
|
|
with this one), keep the password secure!</P
