This chapter is a brief introduction to Netscape and Mosaic. We will cover the following
topics in this chapter:
<UL>
<LI>How to get and set up Netscape for your Linux machine.

<H3 ALIGN="CENTER"><A NAME="Heading3<FONT COLOR="#000077">A Brief Introduction
to Browsers</FONT></H3>
<P>To access the services on the Web, you need a browser. A browser is an application
that knows how to interpret and display documents it finds on the Web. Documents
on the Web are encoded in the Hypertext Markup Language (HTML). Hypertext documents
contain special codes that tell the browser how to locate information on the Web.
How the browser interprets the codes is left as a local issue. Some browsers, such
as Lynx, ignore any requests for inline images; some older Mosaic browsers ignore
the interactive forms that a user can fill in while online. Newer versions of Netscape's
Navigator are great for handling images, entry forms, animated images, and programs
like those in scripting languages such as VBScript and JavaScript.</P>
<P>Any browser you work with must have the following features:
<UL>
<LI>The capability to display plain text, HTML documents, and audio
<P>
<LI>The capability to display inline graphics and images
<P>
<LI>A reasonably customizable graphical user interface
<P>
<LI>The capability to track previous sites with lists in a History and Hotlist
<P>
<LI>The capability to find items via search commands within a document and over the
Internet
<P>
<LI>Extendibility via third-party software items known as plug-ins
</UL>
<P>We will cover the Netscape Navigator and, briefly, the Mosaic browser from NCSA.
The emphasis in this chapter will be on Netscape because I think it is easier to
work with under Linux. If you are a die-hard fan of Mosaic, you will get enough information
from this chapter to be able to get and use it.
<H3 ALIGN="CENTER"><A NAME="Heading4<FONT COLOR="#000077">Getting Navigator
for Linux</FONT></H3>
<P>You need the following items to be able to run Netscape's Navigator on your Linux
machine: an Internet connection (serial or direct), about 10MB of disk space, 8MB
of RAM or better, and X Window running on your machine. Requirements for disk space
might be greater than what I have just quoted here because Navigator uses some disk
space for caching its files. More on that in a bit; let's get the program first.</P>
<P>The latest version of the Netscape Navigator, 3.01, is available free from the
ftp site at <TT>ftp.netscape.com</TT>. This is the directory to go to at <TT>ftp.netscape.com</TT>:</P>
<PRE><FONT COLOR="#0066FF">/pub/navigator/3.01/unix/
</FONT></PRE>
<P>You might find several versions of the Navigator software for different types
of UNIX systems. Get the latest file with the word "linux" in it. You will
most likely get the version that applies to "unknown" and "x86."

<A NAME="Heading5<FONT COLOR="#000077"><B>TIP: </B></FONT>You can try <TT>ftp5.netscape.com</TT>
or <TT>ftp6.netscape.com</TT> if you get a very slow response from <TT>ftp.netscape.com</TT>.
<HR>
</DL>
<P>Use the string <TT>"*linux*"</TT> in the <TT>mget</TT> command. It's
about 2.33MB in a gzipped file, and it takes a some minutes to download, depending
on your connection. Here's an excerpt of a session:</P>
<PRE><FONT COLOR="#0066FF">ftp> mget "*linux*"
mget netscape-v301-export.x86-unknown-linux-elf.tar.gz?y
200 PORT command successful.
150 Opening BINARY mode ... <snip> ... (2338294 bytes).
</FONT></PRE>
<P>After you get the file, you have to unzip it to get the distribution files, including
the <TT>README</TT> file. I prefer to rename the recently downloaded file to something
simple (<TT>myn.tar.gaz</TT>) to avoid goofy typing mistakes. Here are the commands
I used to unzip with the gunzip command and untar the distribution:</P>
<PRE><FONT COLOR="#0066FF">$ mv netscape-v301-export.x86-unknown-linux-elf.tar.gz myn.tar.gz
$ gunzip netscape-v301-export.x86-unknown-linux-elf.tar.gz
$ tar -xvf netscape-v301-export.x86-unknown-linux-elf.tar
</FONT></PRE>
<P>It's a good idea to unzip the file in a directory by itself. This way, you know
which new files you are dealing with. Unzipping the file reveals a bigger tar file.
In the case of Navigator 3.01, the tar file was about 5.5MB, whereas the zipped file
was 2.3MB.</P>
<P>This is what the files in the 3.01 distribution look like (no doubt, later versions
will have different files, dates, and sizes):</P>
