<P>This document currently contains information for Netscape Navigator

only, but I plan to add notes for other browsers too as I get the

necessary information. If you try this with a different browser,

<P>The basic idea here is to give web access to people who wander by,
|
|
while limiting their ability to mess anything up.
|
|
<P>This setup was originally intended for trade shows, but it might be
|
|
applicable other places you want to have a web browser going without
|
|
having to babysit a computer.
|
|
<P>Following these instructions

|
<H3>You need a graphical browser</H3>
|
|
|
|
<P>This document assumes that you already have a running graphical web browser,
|
|
such as Netscape Navigator, on your system.
|
|
You should have permission to use your graphical web browser.
|
|
If you want to use Netscape Navigator in a commercial setting,
|
|
you can buy a copy with appropriate license through Caldera.
|
|
<H3>You need to be able to add an account</H3>
|
|
|
|
<P>If you don't have the right to be <B>root</B>,
|
|
get the system administrator to add the ``<CODE>guest</CODE>'' account
|
|
and give you ownership of <CODE>guest</CODE>'s home directory.
|
|
Skip to the ``Create or edit the following files'' step
|
|
(
|
|
<A HREF="#CreateEditHomeGuestFiles">Create or edit the following files in /home/guest</A>)
|
|
when he or she is done.
|
|
<H3>You need <CODE>httpd</CODE> for a stand-alone web browsing station</H3>
|
|
|
|
<P>If you are setting up a web browsing station to run stand-alone,
|
|
without a network connection,
|
|
you should have <CODE>httpd</CODE> working and the web documents installed.
|

To tell if this is the case, enter:

|

You will be telling people this password.
|

Don't make it the same as your own password.

<P>Then make <CODE>guest</CODE>'s home directory owned by you.

(On Red Hat Linux, these will be the same,

This file disables blink tags, drag-to-select,
|
|
and some of the keyboard commands.
|
|
It also makes all mouse buttons do the same thing,
|
|
hides the menu bar, and makes visited and unvisited links the same color,
|
|
so each visitor gets nice clean blue links,
|
|
not ones that other people have been thumbing through and staining purple.
|
|
<P>You should replace the <CODE>NETSCAPE_GEOMETRY</CODE> in this file
|
|
with an X geometry that looks like this: <CODE>XxY+0-0</CODE>,
|
|
where <CODE>X</CODE> is the width of your screen and <CODE>Y</CODE> is the height
|
|
of your screen <CODE>+ 32</CODE>.
|
|
This will position the Netscape menu bar off the top of the screen,
|
|
so the user won't be distracted.
|
|
For example, if your screen is 800x600,
|
|
the geometry should be <CODE>800x632+0-0</CODE>.
