If login is successful, you should be presented with a shell prompt
|
|
(such as ``<tt>#</tt>'' or ``<tt>$</tt>'') and can happily roam around your
|
|
system. However, there are some initial problems with using the system
|
|
that sometimes creep up.
|
|
<P>
|
|
The most common initial configuration problem is incorrect file or directory
|
|
permissions. This can cause the error message
|
|
<P><TT> Shell-init: permission denied
|
|
<P></TT>
|
|
to be printed after logging in (in fact, any time you see the message
|
|
``<tt>permission denied</tt>'' you can be fairly certain that it is a problem
|
|
with file permissions).

|
In many cases, it's a simple matter of using
|
|
the <tt>chmod</tt> command to fix the permissions of the appropriate files or
|
|
directories.
|
|
For example, some distributions of Linux once
|
|
used the (incorrect) file mode 0644 for the root directory (<tt>/</tt>).
|
|
The fix was to issue the command
|
|
<P><TT> # <em>chmod 755 /</em>
|
|
<P></TT>
|
|
as <tt>root</tt>. However, in order to issue this command, you needed to
|
|
boot from the installation media and mount your Linux root filesystem by
|
|
hand---a hairy task for most newcomers.
|
|
<P>
|
|
As you use the system, you may run into places where file and directory
|
|
permissions are incorrect, or software does not work as configured. Welcome
|
|
to the world of Linux! While most distributions are quite trouble-free,
|
|
very few of them are perfect.
|
|
We don't want to cover all of those problems here.
|
|
Instead, throughout the book we help you to solve many of these configuration
|
|
problems by teaching you how to find them and fix them yourself. In
|
|
Chapter <A HREF="node8.html#chapintronum">1</A> we discussed this philosophy in some detail.
|
|
In Chapter <A HREF="node155.html#chapsysadmnum">4</A>, we give hints
|
|
for fixing many of these common configuration problems.
