  1.  Introduction

  Many people are trying Linux because they are looking for a really
  good Internet capable operating system.  Also, there are institutes,
  universities, non-profits, and small businesses which want to set up
  Internet sites on a small budget. This is where the WWW-HOWTO comes
  in. This document explains how to set up clients and servers for the
  largest part of the Internet - The World Wide Web.

  All prices in this document are stated in US dollars.  This document
  assumes you are running Linux on an Intel platform.  Instructions and
  product availability my vary from platform to platform.  There are
  many links for downloading software in this document.  Whenever
  possible use a mirror site for faster downloading and to keep the load
  down on the main server.

  2.  Setting up WWW client software (Antiquated)

       Please note that the following section is very outdated and
       was last updated in 1997. This section is being kept here
       for historical purposes only. All major distributions of
       Linux come with Netscape and Lynx. These are the two most
       popular browsers for the Linux Operating System. If you do
       not have these browsers installed currently please go to
       their respective sections for download information.

  The following chapter is dedicated to the setting up web browsers.
  Please feel free to contact me, if your favorite web browser is not
  mentioned here.   In this version of the document only a few of the
  browsers have there own section, but I tried to include all of them
  (all I could find) in the overview section.  In the future those
  browsers that deserve there own section will have it.
  The overview section is designed to help you decide which browser to
  use, and give you basic information on each browser.  The detail
  section is designed to help you install, configure, and maintain the
  browser.

  However I use Lynx when I don't feel like firing up the X-
  windows/Netscape monster.

  2.1.  Overview

     ``Navigator/Communicator''
        Netscape Navigator is the only Linux browser mentioned here,
        which is capable of advanced HTML features.  Some of these
        features are frames, Java, Javascript, automatic update, and
        layers.  It also has news and mail capability.  But it is a
        resource hog; it takes up lots of CPU time and memory.  It also
        sets up a separate cache for each user wasting disk space.

        Netscape is currently an OpenSource product and can be
        downloaded from ftp.netscape.com=>.  <tag><ref id= name="Lynx">
        Lynx is the one of the smallest web browsers.  It is the king of
        text based browsers.  It's free and the source code is available
        under the GNU public license.  It's text based, but it has many
        special features. Lynx now supports tables, color (via curses)
        and frames.

          Note on frame support for lynx:

     The frame support for lynx is limited, it will notice the frames
     and show the title of the frames for your to select as hot links.
     Since, frame titles are usually very undescriptive for coding
     simplicity this can be confusing.

     Kfm
        Kfm is part of the K Desktop Environment (KDE).  KDE is a system
        that runs on top of X-windows.  It gives you many features like
        drag an drop, sounds, a trashcan and a unified look and feel.
        Kfm is the K File Manager, but it is also a web browser. It is
        very usable as a web browser and it supports frames, tables, ftp
        downloads, looking into tar files, and more.  The current
        release of KDE is 1.1.1 with 1.1.2 very near by.  Kfm can be
        used without KDE, but you still need the librarys that come with
        KDE.  For more information about KDE and Kfm visit the KDE
        website at  <http://www.kde.org>.

     ``Emacs''
        Emacs is the one program that does everything.  It is a word
        processor, news reader, mail reader, and web browser.  It has a
        steep learning curve at first, because you have to learn what
        all the keys do.  The X-windows version is easier to use,
        because most of the functions are on menus.  Another drawback is
        that it's mostly text based. (It can display graphics if you are
        running it under X-windows).  It is also free, and the source
        code is available under the GNU public license.

     NCSA Mosaic
        Mosaic is an X-windows browser developed by the National Center
        for Supercomputing Applications (NCSA) at the University of
        Illinois.  NCSA spent four years on the project and has now
        moved on to other things.  Again, Mosaic is no longer supported.
        However since the source is free for non-commercial use it might
        make an interesting project for someone who wants to develop a
        new browser.

     Amaya
        Amaya is the X-windows concept browser for the W3C for HTML 3.2.
        Therefore it supports all the HTML 3.2 standards.  It also
        supports some of the features of HTML 4.0.  It supports tables,
        forms, client side image maps, put publishing, gifs, jpegs, and
        png graphics.  It is both a browser and authoring tool.  The
        latest public release is 1.0 beta.  Version 1.1 beta is in
        internal testing and is due out soon.  For more information
        visit the Amaya web site at  <http://www.w3.org/Amaya/>.  It can
        be downloaded from <ftp://ftp.w3.org/pub/Amaya-LINUX-
        ELF-1.0b.tar.gz>.

     Qweb
        Qweb is yet another basic X-windows browser.  It supports
        tables, forms, and server site image maps.  The latest version
        is 1.3.  For more information visit the Qweb website at
        <http://sunsite.auc.dk/qweb/> The source is available from
        <http://sunsite.auc.dk/qweb/qweb-1.3.tar.gz> The binaries are
        available in a Red Hat RPM from
        <http://sunsite.auc.dk/qweb/qweb-1.3-1.i386.rpm>

  It is the reccomendation of this author that users of web browsers use
  either Netscape 4.x, Lynx or Netscape 5.xAlpha. They are the only one
  currently available for Linux that support most features. Personally I
  suggest Netscape5.xAlpha, even though it is Alpha Software it is quite
  stable and frankly implements the standards better than the 4.x
  versions do.

  3.  Lynx

  Lynx is one of the smaller (around 600 K executable) and faster web
  browsers available. It does not eat up much bandwidth nor system
  resources as it only deals with text displays.  It can display on any
  console, terminal or xterm. You will not need an  X Windows system or
  additional system memory to run this little browser.

  3.1.  Where to get

  Most distributions have Lynx in them.  Therefore I will not bore you
  with the details of compiling and installing Lynx.

  The latest version is 2.8.2 and can be retrieved from
  <http://www.slcc.edu/lynx/fote/> or from almost any friendly Linux FTP
  server like ftp://sunsite.unc.edu under /pub/Linux/apps/www/broswers/
  or mirror site.

  For more information on Lynx try these locations:

     Lynx Links
        <http://www.crl.com/~subir/lynx.html>

     Lynx Pages
        <http://lynx.browser.org>

     Lynx Help Pages
        <http://www.crl.com/~subir/lynx/lynx_help/lynx_help_main.html>
        (the same pages you get from lynx --help and typing ? in lynx)

  Note: The Lynx help pages have recently moved.  If you have an older
  version of Lynx, you will need to change your lynx.cfg (in /usr/lib)
  to point to the new address(above).

  I think the most special feature of Lynx against all other web
  browsers is the capability for batch mode retrieval. One can write a
  shell script which retrieves a document, file or anything like that
  via http, FTP, gopher, WAIS, NNTP or file:// - url's and save it to
  disk.  Furthermore, one can fill in data into HTML forms in batch mode
  by simply redirecting the standard input and using the -post_data
  option.

  For more special features of Lynx just look at the help files and the
  man pages.  If you use a special feature of Lynx that you would like
  to see added to this document, let me know.

  4.  Emacs-W3

  There are several different flavors of Emacs.  The two most popular
  are GNU Emacs and XEmacs.  GNU Emacs is put out by the Free Software
  Foundation, and is the original Emacs.  It is mainly geared toward
  text based terminals, but it does run in X-Windows.  XEmacs (formerly
  Lucid Emacs) is a version that only runs on X-Windows.  It has many
  special features that are X-Windows related (better menus etc).

  4.1.  Where to get

  Most distributions include GNU Emacs.

  The most recent GNU emacs is 19.34.  It doesn't seem to have a web
  site.  The FTP site is at  <ftp://ftp.gnu.ai.mit.edu/pub/gnu/>.

  The latest version of XEmacs is 20.2.  The XEmacs FTP site is at
  <ftp://ftp.xemacs.org/pub/xemacs>.  For more information about XEmacs
  goto see its web page at <http://www.xemacs.org>.

  Both are available from the Linux archives at ftp://sunsite.unc.edu
  under /pub/Linux/apps/editors/emacs/

  If you got GNU Emacs or XEmacs installed, you probably got the W3
  browser running to.

  The Emacs W3 mode is a nearly fully featured web browser system
  written in the Emacs Lisp system. It mostly deals with text, but can
  display graphics, too - at least - if you run the emacs under the X
  Window system.

  To get XEmacs in to W3 mode, goto the apps menu and select browse the
  web.

  I don't use Emacs, so if someone will explain how to get it into the
  W3 mode I'll add it to this document.  Most of this information was
  from the original author.  If any information is incorrect, please let
  me know.  Also let me know if you think anything else should be added
  about Emacs.

  5.  Netscape Navigator/Communicator

  5.1.  Different versions and options.

  Netscape Navigator is the King of WWW browsers.  Netscape Navigator
  can do almost everything. But on the other hand, it is one of the most
  memory hungry and resource eating program I've ever seen.

  There are 3 different versions of the program:

  Netscape Navigator includes the web browser, netcaster (push client)
  and a basic mail program.

  Netscape Communicator includes the web browser, a web editor, an
  advanced mail program, a news reader, netcaster (push client), and a
  group conference utility.

  Netscape Communicator Pro includes everything Communicator has plus a
  group calendar, IBM terminal emulation, and remote administration
  features (administrators can update thousands of copies of Netscape
  from their desk).

  In addition to the three versions there are two other options you must
  pick.

  The first is full install or base install.  The full install includes
  everything.  The base install includes enough to get you started.  You
  can download the additional components as you need them (such as
  multimedia support and netcaster).  These components can be installed
  by the Netscape smart update utility (after installing goto
  help->software updates).  At this time the full install is not
  available for Linux.

  The second option is import or export.  If you are from the US are
  Canada you have the option of selecting the import version.  This
  gives you the stronger 128 bit encryption for secure transactions
  (SSL).  The export version only has 40 bit encryption, and is the only
  version allowed outside the US and Canada.

  The latest version of the Netscape Navigator/Communicator/Communicator
  Pro is 4.6.1.  There are two different versions for Linux.  One is for
  the old 1.2 series kernels and one for the new 2.x kernels.  If you
  don't have at least a 2.0 kernel I suggest you upgrade; there are many
  improvements in the new kernel.

  Beta versions are also available.  If you try a beta version, they
  usually expire in a month or so!

  You can also try the 5.0 alpha at the Mozilla project located at
  www.mozilla.org. I suggest this highly, the new Netscape 5 is the best
  browser I have seen in a long time. It is extremely flexible and
  mostly stable even for an Alpha release.

  5.2.  Where to get

  The best way to get Netscape software is to go through their web site
  at <http://www.netscape.com/download/>.  They have menu's to guide you
  through the selection.  When it ask for the Linux version, it is
  referring to the kernel (most people should be using 2.0 by now).  If
  your not sure which version kernel you have run 'cat /proc/version'.
  Going through the web site is the only way to get the import versions.

  If you want an export version you can download them directly from the
  Netscape FTP servers.  The FTP servers are also more up to date. For
  example when I first wrote this the web interface did not have the
  non-beta 4.03 for Linux yet, but it was on the FTP site.  Here are the
  links to the export Linux 2.0 and 2.2 versions:

  Netscape Navigator 4.6.1 is at
  <ftp://ftp.netscape.com/pub/communicator/4.6/shipping/english/unix/linux20/navigator_standalone/navigator-
  v403-export.x86-unknown-linux2.0.tar.gz>

  Netscape Communicator 4.6.1 for Linux 2.0 (kernel) is at
  <ftp://ftp.netscape.com/pub/communicator/4.6/shipping/english/unix/linux20/base_install/communicator-
  v403-export.x86-unknown-linux2.0.tar.gz>

  These url's will change as new versions come out.  If these links
  break you can find them by fishing around at the FTP site
  <ftp://ftp.netscape.com/pub/communicator/>.

  These servers are heavily loaded at times.  Its best to wait for off
  peak hours or select a mirror site.  Be prepared to wait, these
  archives are large.  Navigator is almost 8megs, and Communicator base
  install is 10megs.

  5.3.  Installing

  This section explains how to install version 4 of Netscape Navigator,
  Communicator, and Communicator Pro.

  First unpack the archive to a temporary directory.  Then run the ns-
  install script (type ./ns-install).  Then make a symbolic link from
  the /usr/local/netscape/netscape binary to /usr/local/bin/netscape
  (type ln -s /usr/local/netscape/netscape /usr/local/bin/netscape).
  Finally set the system wide environment variable $MOZILLA_HOME to
  /usr/local/netscape so Netscape can find its files.  If you are using
  bash for your shell edit your /etc/profile and add the lines:

       MOZILLA_HOME="/usr/local/netscape"
       export MOZILLA_HOME

  After you have it installed the software can automatically update
  itself with smart update.  Just run Netscape as root and goto
  help->software updates.  If you only got the base install, you can
  also install the Netscape components from there.

  Note: This will not remove any old versions of Netscape, you must
  manually remove them by deleting the Netscape binary and Java class
  file (for version 3).

  6.  Setting up WWW server systems

  This section contains information on different http server software
  packages and additional server side tools like script languages for
  CGI programs etc.  There are several dozen web servers, I only covered
  those that are fully functional.  As some of these are commercial
  products, I have no way of trying them.  Most of the information in
  the overview section was pieced together from various web sites.  If
  there is any incorrect or missing information please let me know.

  For a technical description on the http mechanism, take a look at the
  RFC documents mentioned in the chapter "For further reading" of this
  HOWTO.

  I prefer to use the Apache server.  It has almost all the features you
  would ever need and its free!  I will admit that this section is
  heavily biased toward Apache.  I decided to concentrate my efforts on
  the Apache section rather than spread it out over all the web servers.
  I may cover other web servers in the future.

  6.1.  Overview

     Cern httpd
        This was the first web server.  It was developed by the European
        Laboratory for Particle Physics (CERN).  CERN httpd is no longer
        supported.  The CERN httpd server is reported to have some ugly
        bugs, to be quite slow and resource hungry.  The latest version
        is 3.0.  For more information visit the CERN httpd home page at
        <http://www.w3.org/Daemon/Status.html>.  It is available for
        download at
        <ftp://sunsite.unc.edu/pub/Linux/apps/www/servers/httpd-3.0.term.tpz>
        (no it is not a typo, the extension is actually .tpz on the
        site; probably should be .tgz)

     NCSA HTTPd
        The NCSA HTTPd server is the father to Apache (The development
        split into two different servers).   Therefore the setup files
        are very similar.  NCSA HTTPd is free and the source code is
        available.  This server not covered in this document, although
        reading the Apache section may give you some help.  The NCSA
        server was once popular, but most people are replacing it with
        Apache.  Apache is a drop in replacement for the NCSA
        server(same configuration files), and it fixes several
        shortcomings of the NCSA server.  NCSA HTTPd accounts for 4.9%
        (and falling) of all web servers. (source September 1997
        Netcraft survey <http://www.netcraft.com/survey/>).  The latest
        version is 1.5.2a.  For more information see the NCSA website at
        <http://hoohoo.ncsa.uiuc.edu>.

     ``Apache''
        Apache is the king of all web servers.  Apache and its source
        code is free.  Apache is modular, therefore it is easy to add
        features.  Apache is very flexible and has many, many features.
        Apache and its derivatives makes up 55% of all web domains.
        There are over 3,928,112 Apache servers in operation (source
        August 1999 Netcraft survey <http://www.netcraft.com/survey/>).

        The official Apache is missing SSL, but there are two
        derivatives that fill the gap.  Stronghold is a commercial
        product that is based on Apache.  It retails for $995; an
        economy version is available for $495 (based on an old version
        of Apache).  Stronghold is the number two secure server behind
        Netscape (source C2 net <http://www.c2.net/products/stronghold>
        and Netcraft survey <http://www.netcraft.com/survey/>).  For
        more information visit the Stronghold website at
        <http://www.c2.net/products/stronghold/>.  It was developed
        outside the US, so it is available with 128 bit SSL everywhere.

        Apache-SSL is a free implementation of SSL, but it is not for
        commercial use in the US (RSA has US patents on SSL technology).
        It can be used for non-commercial use in the US if you link with
        the free RSAREF library.  For more information see the website
        at <http://www.algroup.co.uk/Apache-SSL/>.

     Netscape Fast Track Server
        Fast Track was developed by Netscape, but the Linux version is
        put out by Caldera.  The Caldera site lists it as Fast Track for
        OpenLinux.  I'm not sure if it only runs on Caldera OpenLinux or
        if any Linux distribution will do (E-mail me if you have the
        answer).  Netscape servers account for 6.11% (and RISING!) of
        all web servers (source August 1999
        <http://www.netcraft.com/survey/>).  The server sells for $295.
        It is also included with the Caldera OpenLinux Standard
        distribution which sells for $399 ($199.50 educational).  The
        web pages tell of a nice administration interface and a quick 10
        minute setup.  The server has support for 40-bit SSL.  To get
        the full 128-bit SSL you need Netscape Enterprise Server.
        Unfortunately that is not available for Linux :( The latest
        version available for Linux is 2.0 (Version 3 is in beta, but
        its not available for Linux yet).  To buy a copy goto the
        Caldera web site at
        <http://www.caldera.com/products/netscape/netscape.html> For
        more information goto the Fast Track page at

     WN WN has many features that make it attractive.  First it is
        smaller than the CERN, NCSA HTTPd, an Apache servers.  It also
        has many built-in features that would require CGI's.  For
        example site searches, enhanced server side includes.  It can
        also decompress/compress files on the fly with its filter
        feature.  It also has the ability to retrieve only part of a
        file with its ranges feature.  It is released under the GNU
        public license.  The current version is 2.08. For more
        information see the WN website at <http://hopf.math.nwu.edu/>.

     AOLserver
        AOLserver is made by America Online.  I'll admit that I was
        surprised by the features of a web server coming from AOL.  In
        addition to the standard features it supports database
        connectivity.  Pages can query a database by Structured Query
        Language (SQL) commands.  The database is access through Open
        Database Connectivity (ODBC).  It also has built-in search
        engine and TCL scripting.  If that is not enough you can add
        your own modules through the c Application Programming Interface
        (API).  I almost forgot to mention support for 40 bit SSL.  And
        you get all this for free!  For more information visit the
        AOLserver site at <http://www.aolserver.com/server/>

     CL-HTTP
        CL-HTTP stands for Common Lisp Hypermedia Server.  If you are a
        Lisp programmer this server is for you.  You can write your CGI
        scripts in Lisp.  It has a web based setup function.  It also
        supports all the standard server features.  CL-HTTP is free and
        the source code is available.  For more information visit the
        CL-HTTP website at <http://www.ai.mit.edu/projects/iiip/doc/cl-
        http/home-page.html>

  If you have a commercial purpose (company web site, or ISP), I would
  strongly recommend that you use Apache.  I've also heard that the
  Netscape Server is easy to setup. If you have an internal use you can
  be a bit more flexible. But unless one of them has a feature that you
  just have to use,

  This is only a partial listing of all the servers available.  For a
  more complete list visit Netcraft at

  7.  Apache

  The current version of Apache is 1.3.9.  The main Apache site is at
  <http://www.apache.org/>.  Another good source of information is
  Apacheweek at <http://www.apacheweek.com/>.  The Apache documentation
  is ok, so I'm not going to go into detail in setting up apache.  The
  documentation is on the website and is included with the source (in
  HTML format).  There are also text files included with the source, but
  the HTML version is better.  The documentation should get a whole lot
  better once the Apache Documentation Project gets under way.  Right
  now most of the documents are written by the developers.  Not to
  discredit the developers, but they are a little hard to understand if
  you don't know the terminology.

  7.1.  Where to get

  Apache is included in the Red Hat, Slackware, and OpenLinux
  distributions.  Although they may not be the latest version, they are
  very reliable binaries.  The bad news is you will have to live with
  their directory choices (which are totally different from each other
  and the Apache defaults).

  The source is available from the Apache web site at
  <http://www.apache.org/dist/> Binaries are are also available at
  apache at the same place.  You can also get binaries from sunsite at
  <ftp://sunsite.unc.edu/pub/Linux/apps/www/servers/>.  And for those of
  us running Red Hat the latest binary RPM file can usually be found in
  the contrib directory at <ftp://ftp.redhat.com/pub/contrib/i386/>

  If your server is going to be used for commercial purposes, it is
  highly recommended that you get the source from the Apache website and
  compile it yourself.  The other option is to use a binary that comes
  with a major distribution.  For example Slackware, Red Hat, or
  OpenLinux distributions.  The main reason for this is security.  An
  unknown binary could have a back door for hackers, or an unstable
  patch that could crash your system. This also gives you more control
  over what modules are compiled in, and allows you to set the default
  directories.  It's not that difficult to compile Apache, and besides
  you not a real Linux user until you compile your own programs ;)

  7.2.  Compiling and Installing

  First untar the archive to a temporary directory.  Next change to the
  src directory.  Then edit the Configuration file if you want to
  include any special modules.  The most commonly used modules are
  already included.  There is no need to change the rules or makefile
  stuff for Linux.  Next run the Configure shell script (./Configure).
  Make sure it says Linux platform and gcc as the compiler.  Next you
  may want to edit the httpd.h file to change the default directories.
  The server home (where the config files are kept) default is
  /usr/local/etc/httpd/, but you may want to change it to just
  /etc/httpd/.  And the server root (where the HTML pages are served
  from) default is /usr/local/etc/httpd/htdocs/, but I like the
  directory /home/httpd/html (the Red Hat default for Apache).  If you
  are going to be using su-exec (see special features below) you may
  want to change that directory too.  The server root can also be
  changed from the config files too.  But it is also good to compile it
  in, just encase Apache can't find or read the config file.  Everything
  else should be changed from the config files.  Finally run make to
  compile Apache.

  If you run in to problems with include files missing, check the
  following things. Make sure you have the kernel headers (include
  files) installed for your kernel version. Also make sure you have
  these symbolic links in place:

       /usr/include/linux should be a link to /usr/src/linux/include/linux
       /usr/include/asm should be a link to /usr/src/linux/include/asm
       /usr/src/linux should be a link to the Linux source directory (ex.linux-2.0.30)

  Links can be made with ln -s, it works just like the cp command except
  it makes a link (ln -s source-dir destination-link)

  When make is finished there should be an executable named httpd in the
  directory.  This needs to be moved in to a bin directory.  /usr/sbin
  or /usr/local/sbin would be good choices.

  Copy the conf, logs, and icons sub-directories from the source to the
  server home directory.  Next rename 3 of the files files in the conf
  sub-directory to get rid of the -dist extension (ex. httpd.conf-dist
  becomes httpd.conf)

  There are also several support programs that are included with Apache.
  They are in the support directory and must be compiled and installed
  separately.  Most of them can be make by using the makefile in that
  directory (which is made when you run the main Configure script).  You
  don't need any of them to run Apache, but some of them make the
  administrators job easier.

  7.3.  Configuring

  Now you should have four files in your conf sub-directory (under your
  server home directory).  The httpd.conf sets up the server daemon
  (port number, user, etc).  The srm.conf sets the root document tree,
  special handlers, etc.  The access.conf sets the base case for access.
  Finally mime.types tells the server what mime type to send to the
  browser for each extension.

  The configuration files are pretty much self-documented (plenty of
  comments), as long as you understand the lingo.  You should read
  through them thoroughly before putting your server to work.  Each
  configuration item is covered in the Apache documentation.

  The mime.types file is not really a configuration file.  It is used by
  the server to translate file extensions into mime-types to send to the
  browser.  Most of the common mime-types are already in the file.  Most
  people should not need to edit this file.  As time goes on, more mime
  types will be added to support new programs.  The best thing to do is
  get a new mime-types file (and maybe a new version of the server) at
  that time.

  Always remember when you change the configuration files you need to
  restart Apache or send it the SIGHUP signal with kill for the changes
  to take effect.  Make sure you send the signal to the parent process
  and not any of the child processes.  The parent usually has the lowest
  process id number.  The process id of the parent is also in the
  httpd.pid file in the log directory.  If you accidently send it to one
  of the child processes the child will die and the parent will restart
  it.

  I will not be walking you through the steps of configuring Apache.
  Instead I will deal with specific issues, choices to be made, and
  special features.

  I highly recommend that all users read through the security tips in
  the Apache documentation.  It is also available from the Apache
  website at <http://www.apache.org/docs/mics/security_tips.html>.

  7.4.  Hosting virtual websites

  Virtual Hosting is when one computer has more than one domain name.
  The old way was to have each virtual host have its own IP address.
  The new way uses only one IP address, but it doesn't work correctly
  with browsers that don't support HTTP 1.1.

  My recommendation for businesses is to go with the IP based virtual
  hosting until most people have browsers that support HTTP 1.1 (give it
  a year or two).   This also gives you a more complete illusion of
  virtual hosting.  While both methods can give you virtual mail
  capabilities (can someone confirm this?), only IP based virtual
  hosting can also give you virtual FTP as well.

  If it is for a club or personal page, you may want to consider shared
  IP virtual hosting.  It should be cheaper than IP based hosting and
  you will be saving precious IP addresses.

  You can also mix and match IP and shared IP virtual hosts on the same
  server.  For more information on virtual hosting visit Apacheweek at
  <http://www.apacheweek.com/features/vhost>.

  7.4.1.  IP based virtual hosting

  In this method each virtual host has its own IP address.  By
  determining the IP address that the request was sent to, Apache and
  other programs can tell what domain to serve.  This is an incredible
  waste of IP space.  Take for example the servers where my virtual
  domain is kept.  They have over 35,000 virtual accounts, that means
  35,000 IP addresses.  Yet I believe at last count they had less than
  50 servers running.

  Setting this up is a two part process.  The first is getting Linux
  setup to accept more than one IP address.  The second is setting up
  apache to serve the virtual hosts.

  The first step in setting up Linux to accept multiple IP addresses is
  to make a new kernel.  This works best with a 2.0 series kernel (or
  higher).  You need to include IP networking and IP aliasing support.
  If you need help with compiling the kernel see the kernel howto
  <http://sunsite.unc.edu/LDP/HOWTO/Kernel-HOWTO.html>.

  Next you need to setup each interface at boot.  If you are using the
  Red Hat Distribution then this can be done from the control panel.
  Start X-windows as root, you should see a control panel.  Then double
  click on network configuration.  Next goto the interfaces panel and
  select your network card.  Then click alias at the bottom of the
  screen.  Fill in the information and click done.  This will need to be
  done for each virtual host/IP address.

  If you are using other distributions you may have to do it manually.
  You can just put the commands in the rc.local file in /etc/rc.d
  (really they should go in with the networking stuff).  You need to
  have a ifconfig and route command for each device.  The aliased
  addresses are given a sub device of the main one.  For example eth0
  would have aliases eth0:0, eth0:1, eth0:2, etc.  Here is an example of
  configuring a aliased device:

       ifconfig eth0:0 192.168.1.57
       route add -host 192.168.1.57 dev eth0:0

  You can also add a broadcast address and a netmask to the ifconfig
  command.  If you have alot of aliases you may want to make a for loop
  to make it easier.  For more information see the IP alias mini howto
  <http://sunsite.unc.edu/LDP/HOWTO/mini/IP-Alias.html>.

  Then you need to setup your domain name server (DNS) to serve these
  new domains.   And if you don't already own the domain names, you need
  to contact the Internic <http://www.internic.net> to register the
  domain names.  See the DNS-howto for information on setting up your
  DNS.

  Finally you need to setup Apache to server the virtual domain
  correctly.  This is in the httpd.conf configuration file near the end.
  They give you an example to go by.  All commands specific to that
  virtual host are put in between the virtualhost directive tags.  You
  can put almost any command in there.  Usually you set up a different
  document root, script directory, and log files. You can have almost
  unlimited number of virtual hosts by adding more virtualhost directive
  tags.

  In rare cases you may need to run separate servers if a directive is
  needed for a virtual host, but is not allowed in the virtual host
  tags.  This is done using the bindaddress directive.   Each server
  will have a different name and setup files.  Each server only responds
  to one IP address, specified by the bindaddress directive.  This is an
  incredible waste of system resources.

  7.4.2.  Shared IP virtual hosting

  This is a new way to do virtual hosting.  It uses a single IP address,
  thus conserving IP addresses for real machines (not virtual ones).  In
  the same example used above those 30,000 virtual hosts would only take
  50 IP addresses (one for each machine).  This is done by using the new
  HTTP 1.1 protocol.  The browser tells the server which site it wants
  when it sends the request.  The problem is browsers that don't support
  HTTP 1.1 will get the servers main page, which could be setup to
  provide a menu of virtual hosts available.  That ruins the whole
  illusion of virtual hosting.  The illusion that you have your own
  server.

  The setup is much simpler than the IP based virtual hosting.  You
  still need to get your domain from the Internic and setup your DNS.
  This time the DNS points to the same IP address as the original
  domain.  Then Apache is setup the same as before.  Since you are using
  the same IP address in the virtualhost tags, it knows you want Shared
  IP virtual hosting.

  There are several work arounds for older browsers.  I'll explain the
  best one.  First you need to make your main pages a virtual host
  (either IP based or shared IP).  This frees up the main page for a
  link list to all your virtual hosts.  Next you need to make a back
  door for the old browsers to get in.  This is done using the
  ServerPath directive for each virtual host inside the virtualhost
  directive.  For example by adding ServerPath /mysite/ to
  www.mysite.com old browsers would be able to access the site by
  www.mysite.com/mysite/.  Then you put the default page on the main
  server that politely tells them to get a new browser, and lists links
  to all the back doors of all the sites you host on that machine.  When
  an old browser accesses the site they will be sent to the main page,
  and get a link to the correct page.  New browsers will never see the
  main page and will go directly to the virtual hosts.  You must
  remember to keep all of your links relative within the web sites,
  because the pages will be accessed from two different URL's
  (www.mysite.com and www.mysite.com/mysite/).

  I hope I didn't lose you there, but its not an easy workaround.  Maybe
  you should consider IP based hosting after all.  A very similar
  workaround is also explained on the apache website at
  <http://www.apache.org/manual/host.html>.

  If anyone has a great resource for Shared IP hosting, I would like to
  know about it.  It would be nice to know what percent of browsers out
  there support HTTP 1.1, and to have a list of which browsers and
  versions support HTTP 1.1.

  7.5.  CGI scripts

  There are two different ways to give your users CGI script capability.
  The first is make everything ending in .cgi a CGI script.  The second
  is to make script directories (usually named cgi-bin).  You could also
  use both methods.  For either method to work the scripts must be world
  executable (chmod 711).  By giving your users script access you are
  creating a big security risk.  Be sure to do your homework to minimize
  the security risk.

  I prefer the first method, especially for complex scripting.  It
  allows you to put scripts in any directory.  I like to put my scripts
  with the web pages they work with.  For sites with allot of scripts it
  looks much better than having a directory full of scripts.  This is
  simple to setup.  First uncomment the .cgi handler at the end of the
  srm.conf file.  Then make sure all your directories have the option
  ExecCGI or All in the access.conf file.

  Making script directories is considered more secure.  To make a script
  directory you use the ScriptAlias directive in the srm.conf file.  The
  first argument is the Alias the second is the actual directory.  For
  example ScriptAlias /cgi-bin/ /usr/httpd/cgi-bin/ would make
  /usr/httpd/cgi-bin able to execute scripts.  That directory would be
  used whenever someone asked for the directory /cgi-bin/.  For security
  reasons you should also change the properties of the directory to
  Options none, AllowOveride none in the access.conf (just uncomment the
  example that is there).  Also do not make your script directories
  subdirectories of your web page directories.  For example if you are
  serving pages from /home/httpd/html/, don't make the script directory
  /home/httpd/html/cgi-bin; Instead make it /home/httpd/cgi-bin.

  If you want your users to have there own script directories you can
  use multiple ScriptAlias commands.  Virtual hosts should have there
  ScriptAlias command inside the virtualhost directive tags.  Does
  anyone know a simple way to allow all users to have a cgi-bin
  directory without individual ScriptAlias commands?

  7.6.  Users Web Directories

  There are two different ways to handle user web directories.  The
  first is to have a subdirectory under the users home directory
  (usually public_html).  The second is to have an entirely different
  directory tree for web directories.  With both methods make sure set
  the access options for these directories in the access.conf file.

  The first method is already setup in apache by default.  Whenever a
  request for /~bob/ comes in it looks for the public_html directory in
  bob's home directory.  You can change the directory with the UserDir
  directive in the srm.conf file.  This directory must be world readable
  and executable.  This method creates a security risk because for
  Apache to access the directory the users home directory must be world
  executable.

  The second method is easy to setup.  You just need to change the
  UserDir directive in the srm.conf file.  It has many different
  formats; you may want to consult the Apache documentation for
  clarification.  If you want each user to have their own directory
  under /home/httpd/, you would use UserDir /home/httpd.  Then when the
  request /~bob/ comes in it would translate to /home/httpd/bob/.  Or if
  you want to have a subdirectory under bob's directory you would use
  UserDir /home/httpd/*/html.  This would translate to
  /home/httpd/bob/html/ and would allow you to have a script directory
  too (for example /home/httpd/bob/cgi-bin/).

  7.7.  Daemon mode vs. Inetd mode

  There are two ways that apache can be run.  One is as a daemon that is
  always running (Apache calls this standalone).  The second is from the
  inetd super-server.

  Daemon mode is far superior to inetd mode.  Apache is setup for daemon
  mode by default.  The only reason to use the inetd mode is for very
  low use applications.  Such as internal testing of scripts, small
  company Intranet, etc.  Inetd mode will save memory because apache
  will be loaded as needed.   Only the inetd daemon will remain in
  memory.

  If you don't use apache that often you may just want to keep it in
  daemon mode and just start it when you need it.  Then you can kill it
  when you are done (be sure to kill the parent and not one of the child
  processes).

  To setup inetd mode you need to edit a few files.  First in
  /etc/services see if http is already in there.  If its not then add
  it:

       http    80/tcp

  Right after 79 (finger) would be a good place.  Then you need to edit
  the /etc/inetd.conf file and add the line for Apache:

  http    stream  tcp     nowait  root    /usr/sbin/httpd httpd

  Be sure to change the path if you have Apache in a different location.
  And the second httpd is not a typo; the inet daemon requires that.  If
  you are not currently using the inet daemon, you may want to comment
  out the rest of the lines in the file so you don't activate other ser­
  vices as well (FTP, finger, telnet, and many other things are usually
  run from this daemon).

  If you are already running the inet deamon (inetd), then you only need
  to send it the SIGHUP signal (via kill; see kill's man page for more
  info) or reboot the computer for changes to take effect.  If you are
  not running inetd then you can start it manually.  You should also add
  it to your init files so it is loaded at boot (the rc.local file may
  be a good choice).

  7.8.  Allowing put and delete commands

  The newer web publishing tools support this new method of uploading
  web pages by http (instead of FTP).  Some of these products don't even
  support FTP anymore!  Apache does support this, but it is lacking a
  script to handle the requests.  This script could be a big security
  hole, be sure you know what you are doing before attempting to write
  or install one.

  If anyone knows of a script that works let me know and I'll include
  the address to it here.

  For more information goto Apacheweek's article at
  <http://www.apacheweek.com/features/put>.

  7.9.  User Authentication/Access Control

  This is one of my favorite features.  It allows you to password
  protect a directory or a file without using CGI scripts.  It also
  allows you to deny or grant access based on the IP address or domain
  name of the client.  That is a great feature for keeping jerks out of
  your message boards and guest books (you get the IP or domain name
  from the log files).

  To allow user authentication the directory must have AllowOverrides
  AuthConfig set in the access.conf file.  To allow access control (by
  domain or IP address) AllowOverrides Limit must be set for that
  directory.

  Setting up the directory involves putting an .htaccess file in the
  directory.  For user authentication it is usually used with an
  .htpasswd and optionally a .htgroup file.  Those files can be shared
  among multiple .htaccess files if you wish.

  For security reasons I recommend that everyone use these directives in
  there access.conf file:

       <files ~ "/\.ht">
       order deny,allow
       deny from all
       </files>

  If you are not the administrator of the system you can also put it in
  your .htaccess file if AllowOverride Limit is set for your directory.
  This directive will prevent people from looking into your access
  control files (.htaccess, .htpasswd, etc).

  There are many different options and file types that can be used with
  access control.  Therefore it is beyond the scope of this document to
  describe the files.  For information on how to setup User
  Authentication see the Apacheweek feature at
  <http://www.apacheweek.com/features/userauth> or the NCSA pages at
  <http://hoohoo.ncsa.uiuc.edu/docs-1.5/tutorials/user.html>.

  7.10.  su-exec

  The su-exec feature runs CGI scripts as the user of the owner.
  Normally it is run as the user of the web server (usually nobody).
  This allows users to access there own files in CGI scripts without
  making them world writable (a security hole).  But if you are not
  careful you can create a bigger security hole by using the su-exec
  code.  The su-exec code does security checks before executing the
  scripts, but if you set it up wrong you will have a security hole.

  The su-exec code is not for amateurs.  Don't use it if you don't know
  what you are doing.  You could end up with a gaping security hole
  where your users can gain root access to your system.  Do not modify
  the code for any reason.  Be sure to read all the documentation
  carefully.  The su-exec code is hard to setup on purpose, to keep the
  amateurs out (everything must be done manually, no make file no
  install scripts).

  The su-exec code resides in the support directory of the source.
  First you need to edit the suexec.h file for your system.  Then you
  need to compile the su-exec code with this command:

       gcc suexec.c -o suexec

  Then copy the suexec executable to the proper directory.  The Apache
  default is /usr/local/etc/httpd/sbin/.  This can be changed by editing
  httpd.h in the Apache source and recompiling Apache.  Apache will only
  look in this directory, it will not search the path.  Next the file
  needs to be changed to user root (chown root suexec) and the suid bit
  needs to be set (chmod 4711 suexec).  Finally restart Apache, it
  should display a message on the console that su-exec is being used.

  CGI scripts should be set world executable like normal.  They will
  automaticaly be run as the owner of the CGI script.  If you set the
  SUID (set user id) bit on the CGI scripts they will not run.  If the
  directory or file is world or group writable the script will not run.
  Scripts owned by system users will not be run (root, bin, etc.).  For
  other security conditions that must be met see the su-exec
  documentation.  If you are having problems see the su-exec log file
  named cgi.log.

  Su-exec does not work if you are running Apache from inetd, it only
  works in daemon mode.  It will be fixed in the next version because
  there will be no inetd mode.  If you like playing around in source
  code, you can edit the http_main.c.  You want to get rid of the line
  where Apache announces that it is using the su-exec wrapper (It
  wrongly prints this in front of the output of everything).

  Be sure and read the Apache documentation on su-exec.  It is included
  with the source and is available on the Apache web site at
  <http://www.apache.org/docs/suexec.html>

  7.11.  Imagemaps

  Apache has the ability to handle server side imagemaps.  Imagemaps are
  images on webpages that take users to different locations depending on
  where they click.  To enable imagemaps first make sure the imagemap
  module is installed (its one of the default modules).  Next you need
  to uncomment the .map handler at the end of the srm.conf file.  Now
  all files ending in .map will be imagemap files.  Imagemap files map
  different areas on the image to separate links.  Apache uses map files
  in the standard NCSA format.  Here is an example of using a map file
  in a web page:

       <a href="/map/mapfile.map">
       <img src="picture.gif" ISMAP>
       </a>

  In this example mapfile.map is the mapfile, and picture.gif is the
  image to click on.

  There are many programs that can generate NCSA compatible map files or
  you can create them yourself.  For a more detailed discussion of
  imagemaps and map files see the Apacheweek feature at
  <http://www.apacheweek.com/features/imagemaps>.

  7.12.  SSI/XSSI

  Server Side Includes (SSI) adds dynamic content to otherwise static
  web pages.  The includes are embedded in the web page as comments.
  The web server then parses these includes and passes the results to
  the web server.  SSI can add headers and footers to documents, add
  date the document was last updated, execute a system command or a CGI
  script.  With the new eXtended Server Side Includes (XSSI) you can do
  a whole lot more.  XSSI adds variables and flow control statements
  (if, else, etc).  Its almost like having an programming language to
  work with.

  Parsing all HTML files for SSI commands would waste allot of system
  resources.  Therefore you need to distinguish normal HTML files from
  those that contain SSI commands.  This is usually done by changing the
  extension of the SSI enhanced HTML files.  Usually the .shtml
  extension is used.

  To enable SSI/XSSI first make sure that the includes module is
  installed.  Then edit srm.conf and uncomment the AddType and
  AddHandler directives for .shtml files.   Finally you must set Options
  Includes for all directories where you want to run SSI/XSSI files.
  This is done in the access.conf file.  Now all files with the
  extension .shtml will be parsed for SSI/XSSI commands.

  Another way of enabling includes is to use the XBitHack directive.  If
  you turn this on it looks to see if the file is executable by user.
  If it is and Options Includes is on for that directory, then it is
  treated as an SSI file.  This only works for files with the mime type
  text/html (.html .htm files).  This is not the preferred method.

  There is a security risk in allowing SSI to execute system commands
  and CGI scripts.  Therefore it is possible to lock that feature out
  with the Option IncludesNOEXEC instead of Option Includes in the
  access.conf file.  All the other SSI commands will still work.

  For more information see the Apache mod_includes documentation that
  comes with the source.  It is also available on the website at
  <http://www.apache.org/docs/mod/mod_include.html>.

  For a more detailed discussion of SSI/XSSI implementation see the
  Apacheweek feature at  <http://www.apacheweek.com/features/ssi>.

  Coming soon: mSQL, PHP/FI, cgiwrap, Fast-cgi, MS frontpage extentions,
  and more.

  9.  Intranet Section

  In simple terms, the Intranet is the descriptive term being used for
  the implementation of Internet technologies within a corporate
  organisation, rather than for external connection to the global
  Internet. This implementation is performed in such a way as to
  transparently deliver the immense informational resources of an
  organisation to each individuals desktop with minimal cost, time and
  effort. This document attempts to explain in simple terms how to setup
  an Intranet using tools which are readily available and are generally
  costing little or are free.

  This document assumes that you already know how to install TCP/IP on
  your Linux server and connect it physically to your LAN using an
  Ethernet network card. This also assumes you have some basic knowledge
  of Netware, WinNT and Mac systems. The configuration of the Netware
  server has been shown using version 3.1x as the basis. You can also
  use INETCFG to achieve the same result. On the client side the
  discussion is with respect to Windows 3.1x, Windows for Workgroups and
  Win95, WinNT and the Apple PowerMac.

  I am using the private network addresses (RFC-1918) of 172.16.0.0 and
  172.17.0.0 only as examples. You may choose suitable addresses
  depending on your configuration.

              Linux       Netware      WFWG/WinNT
              Server      Server       Server
             172.16.0.1   172.16.0.2   172.16.0.3

  10.  Install the HTTP server

  When you download the server you have two options: To get the source
  and compile it yourself, or get the precompiled binaries. The
  precompiled binaries for Linux (ELF) version are available at NCSA but
  not the older versions.

  10.1.  Preparation before downloading

  The server at NCSA will guide you through the steps for configuration
  options and prepare the various files for you. But before you attempt
  to download HTTPd be prepared with answers to the following questions

  10.1.1.  The Operating System

  First, you must choose whether to download the source or a pre-
  compiled version of the software. If your particular system doesn't
  appear in the menu, then you will have to get the default source, and
  compile it yourself.

  To check the version of your Linux go to the command prompt on your
  Linux machine and type

         linux:~$  uname -a

  which will respond with a line which looks similar to this

          linux:~$  uname -a
          Linux linux 2.0.29 #4 Tue Sep 13 04:05:51 CDT 1994 i586
          linux:~$

  The version of Linux is 2.0.29.

  The remaining parameters can be specified before downloading or
  configured later by modifying the file srm.conf in the
  /usr/local/etc/httpd/conf directory. The names of the actual
  directives that appear in the file httpd.conf are shown in brackets.
  The only exception is the directive DocumentRoot which appears in the
  file srm.conf

  10.1.2.  Process type (ServerType)

  This specifies how your machine will run your HTTPd server. The
  preferred method is "standalone". This makes the HTTP daemon to be
  running constantly. If you choose to load HTTPd under "inetd", the
  server binary will be reloaded into memory for every request, which
  may slow your server down.

  10.1.3.  Binding Port (Port)

  This specifies which port of your machine that the HTTPd daemon will
  bind to and listen for HTTP requests. If you can login as "root", use
  the default setting of 80.  Otherwise choose a setting between 1025
  and 65535.
  10.1.4.  Server user identity (User)

  This is the user id the server will change to when answering requests
  and acting on files.This question needs to be answered only if you are
  running the server as "standalone".  If you are someone without root
  permissions, just use your own login name. If you are system
  administrator, you might want to create a special user so you can
  control file permissions.

  10.1.5.  Server group identity (Group)

  This is the group id the server will change to when answering requests
  and acting on files. This is similar to Server User identity and is
  applicable only if you are running the server as standalone.

  If you do not have root permissions, just use the name of your primary
  group. You can find out your group by typing groups at the Linux
  command prompt.

  10.1.6.  Server administrator email address (ServerAdmin)

  This is the email address that the user should send an email message
  to when reporting a problem with the server. You can put your personal
  e-mail address.

  10.1.7.  Location of server directory (ServerRoot)

  This is where the server resides on your system. If you have root
  permissions leave it in its recommended location /usr/local/etc/httpd.
  If you cannot login as root, choose a subdirectory in your home path.
  You can find out the path of your home directory with the pwd command.

  10.1.8.  Location of HTML files (DocumentRoot)

  This is where the HTML files to be served are located. The default
  location is /usr/local/etc/httpd/htdocs.  You could however set it to
  be the home directory of the special user you chose in Server user
  identity, or a subdirectory in your home directory if you can't login
  as root.

  When in doubt, use the default settings. Now that you have answers to
  the above questions you can Download NCSA HTTPd at
  http://hoohoo.ncsa.uiuc.edu/docs/setup/OneStep.html.  You should read
  the HTTPd Documentation at http://hoohoo.ncsa.uiuc.edu/docs/ before
  you attempt installation. If you are planning to compile the code then
  you need to modify the makefiles in each of the th ree directories
  support, src, cgi-src. If your version of Linux is already supported
  then you just have to type make linux at the top level directory (i.e.
  /usr/local/etc/httpd)

  10.2.  Compiling HTTPd

  Compiling is simple, just type make linux at the prompt in the server
  root directory.  Note: Users of pre-ELF Linux have to uncomment
  #define NO_PASS in file portability.h and set DBM_LIBS= -ldbm in the
  Makefile before compiling HTTPd.

  11.  Testing HTTPd

  After you have installed HTTPd, login as root and start it by typing
  httpd & . (assuming you have installed as standalone) You should now
  be able to see it in the list generated by ps. The simplest way to
  test HTTPd is by Telnet. At the Linux command prompt type

          linux:~$  telnet 172.16.0.1 80

  where 80 is the default port for HTTP. If you have configured "Port"
  as something different then type that number instead. You should get a
  response which looks like this

          Trying 172.16.0.1...
          Connected to linux.mydomain.
          Escape character is '^]'.

  Now if you type in any character and press Enter you should get a
  response similar to the one shown below.

          HTTP/1.0 400 Bad Request
          Date: Wed, 10 Jan 1996 10:24:37 GMT
          Server: NCSA/1.5
          Content-type: text/html

          <HEAD><TITLE>400 Bad Request < /TITLE> < /HEAD>
          <BODY><H1>400 Bad Request < /H1>
          Your client sent a query that this server could
          not understand.<P>
          Reason: Invalid or unsupported method.<P>
          < /BODY>

  Now we are ready to connect to this server using another PC and a WWW
  Browser.

  12.  Connecting to the Linux Server

  Please refer to the diagram shown in the chapter ``Introduction'' for
  the addressing scheme used. Workstation 1 (W/S1) is on network
  172.16.0.0 and can access the Linux server directly whereas
  Workstation 2 (W/S2) is on network 172.17.0.0 and needs to use the
  gateway (router) 172.17.0.254 to access the Linux box. This gateway
  information needs to be provided while configuring the clients only on
  W/S2. Netware refers to the gateway as 'ip_router'.

  I am using W/S2 to illustrate the client setup. To setup W/S1 just
  change the address 172.17.0.5 to 172.16.0.5 and ignore all references
  to the gateway/router.

  If you do not have a router you can skip the next section and proceed
  to

  ·  ``Setup Netware Server'' if you use a Netware server.

  ·  ``Setup MS Windows Client'' if you use the Microsoft Client.

  12.1.  Setup the Linux server

  You may skip this section if you do not have a router.

  You have to configure the Linux server to recognise the router thus
  allowing Workstation 2 to connect to the Web server. In order to setup
  the Linux server you should login as root. At the server prompt type

          route add gw default 172.16.0.254

  To use this gateway everytime you boot the Linux server edit the file
  /etc/rc.d/rc.inet1 and change the line containing the gateway defini­
  tion to GATEWAY = "172.16.0.254". Make sure the line for adding the
  gateway is not commented out.

  ALT: You can add routes to the networks on the other side of the
  router. This would be done as

          route add -net 172.17.0.0 gw 172.16.0.254

  To add this route everytime you boot Linux add the command to your
  /etc/rc.d/rc.local file.

  12.2.  Setup the Netware server

  In order to setup the Netware server you should have Supervisor
  permissions or atleast Console operator permissions. If these cannot
  be got, try asking your Network Administrator to help you with the
  setup.  At the Server enable the Ethernet_II frame type on the LAN by
  typing these commands or include them in the AUTOEXEC.ncf file.

          load NE2000 frame=Ethernet_II name=IPNET
          load TCPIP
          bind IP to IPNET addr=172.16.0.2 mask=FF.FF.FF.0

  You might have to specify the slot or board number while loading the
  NE2000 driver depending on your machine configuration. (eg: load
  NE2000 slot=3 frame=.....)

  12.3.  Setup the Netware Client

  On the PC you have the choice of Win3.1,WFWG or Win95. The
  installation procedure differs between Win95 and the older windows if
  you are using the 32bit client from Microsoft or Novell. If you are
  going to use the 16bit client, the procedure is the same and you can
  refer to the Windows 3.x installation instructions. For installing the
  32bit client for Win95 skip to ``Windows 95 installation''.

  12.3.1.  Windows 3.x

  If you are using Win3.1 or WFWG you can install the Netware Client
  (VLMs) and some additional files which are provided with the TCP/IP
  diskette, namely

  TCPIP.exe, VTCPIP.386, WINSOCK.dll and WLIBSOCK.dll

  Note that the WINSOCK.dll file is different from the ones provided
  with Win95 and Trumpet. Install the Netware Client with the support
  for windows. Copy VTCPIP.386, WINSOCK.dll and WLIBSOCK.dll to the
  SYSTEM directory and TCPIP.exe to the NWCLIENT directory. Now modify
  the STARTNET.bat in the NWCLIENT directory to

          lsl
          ne2000     ---> your network card driver
          c:\windows\odihlp.exe     ---->if you are using WFWG
          ipxodi
          tcpip        ---> add this line
          nwip         ---> if you use Netware/IP
          vlm

  Create a subdirectory (say) \NET\TCP and copy the files HOSTS,
  NETWORKS, PROTOCOLS and SERVICES from /etc on your Linux server or the
  directory SYS:ETC on your Netware server. Edit the copied HOSTS file
  to add the line for your new Linux server. This will enable you to
  refer to the Linux server as http://linux.mydomain/ instead of
  http://172.16.0.1/in your WWW browser

          127.0.0.1      localhost
          172.16.0.1      linux.mydomain

  Edit the NET.cfg file in NWCLIENT directory

     Link Driver NE2000
         port 300
         int 3
         MEM D0000
         FRAME Ethernet_802.2

  ; ---- add these lines ----

        FRAME Ethernet_II

     Protocol TCPIP
        PATH TCP_CFG C:\NET\TCP
        ip_address  172.17.0.5
        ip_netmask  255.255.255.0
        ip_router   172.17.0.254     ---> add the address of your gateway only
                                    ---> if you have to use this
                                    ---> gateway to reach your HTTP server

     Link Support
        MemPool 6192       ---> the minimum is 1024. Try with different values
        Buffers 10 1580    ---> this again can be fine tuned

  ;---------------------------------
  ; You may need to add lines like these if you are using Netware/IP
  ;
     NWIP
        NWIP_DOMAIN_NAME  mydomain
        NSQ_BROADCAST   ON
        NWIP1_1 COMPATIBILITY   OFF
        AUTORETRIES     1
        AUTORETRY SECS  10

  Edit the SYSTEM.ini file in the WINDOWS directory and add this entry
  for VTCPIP.386

          [386Enh]
          .....
          network=*vnetbios, vipx.386, vnetware.386, VTCPIP.386
          .....

  Reboot your PC, run STARTNET.bat and you can now use your favorite WWW
  browser to access your Web pages. You need not login to Netware and
  you don't have to run TCPMAN (if you use Trumpet Winsock).

  12.3.2.  Windows 95

  This section explains how to install the 32bit client on Win95.
  Firstly you must install the following

          Client for Netware Networks (from Microsoft or Novell)
          Microsoft TCP/IP Protocol
          Network Adapter

  To install these items, click on My Computer, Control Panel, Networks.
  Click Add. You will now be in a window that displays Client, Adapter,
  Protocol and Service.  To install the Client for Netware Networks:

         1. DoubleClick on Client
         2. Click on Microsoft or Novell
         3. DoubleClick on Client for Netware Networks

  To install the TCP/IP Protocol:

         1. DoubleClick on Protocol
         2. Click on Microsoft
         3. DoubleClick on TCP/IP

  Windows 95 by default installs several other protocols automatically.
  Remove them by clicking on them and clicking the Remove button.
  Typically Win95 installs the Microsoft NetBeui protocol, and IPX/SPX
  compatible protocol. You can delete the NetBEUI protocol, but you will
  need the IPX/SPX protocol if you wish to login to the Netware Server.

  To setup TCP/IP click on TCP/IP, click on Properties, click on the tab
  IP address

         Enter your IP address in the "Specify an IP address "
                               box as 172.17.0.5
         In the Subnet Mask box enter 255.255.255.0

  select the tab Gateway

         Enter your gateway (router) address in the box New gateway
            as 172.17.0.254
         Click the Add button

  The gateway address should now appear under the installed gateways
  box. Now Click OK.

  You should get a message to reboot. Do so. You should now be able to
  use the Browser to connect to your HTTP Server.

  12.4.  Setup Microsoft Client

  If you are using the Microsoft Client for accessing your network, then
  this section details how to install TCP/IP for

  ·  ``Windows for Workgroups (WFWG)''

  ·  ``Windows 95''

  ·  ``Windows NT 4.0''

     Note: To enable you to refer to the Linux server as
     http://linux.mydomain/ instead of http://172.16.0.1/ in the WWW
     browser and all your intranet commands you need to edit the hosts
     file. You can add more entries for each of your other hosts
     (Netware, Unix, WinNT) as well. The Windows family keeps its HOSTS
     file in \WINDOWS or in \WINDOWS\SYSTEM depending on the version.
     Edit this file and add a line for your Linux server as:

          127.0.0.1      localhost
          172.16.0.1     linux.mydomain

          172.16.0.2     netware.mydomain
          172.16.0.3     winNT.mydomain
          172.16.0.5     ws_1

  12.4.1.  Windows for Workgroups

  This section explains how to install the 32bit client on WFWG. Firstly
  you must download the TCP/IP drivers for Windows from Microsoft. The
  current version is 3.11b and is available at ftp://ftp.microsoft.com
  or other sites as tcp32b.exe. Make sure that you have load Win32s
  before trying to load the TCP/IP-32bit driver.

  Having expanded the TCP/IP files into a temporary directory (say
  C:\TEMP), check your \WINDOWS\SYSTEM directory for copies of
  OEMSETUP.INF. If there are any, rename them. Now copy the OEMSETUP.INF
  file from the TEMP directory to the \WINDOWS\SYSTEM directory. If you
  have loaded any other TCP/IP stacks on your system, please remove them
  before you proceed.

  Start Network Setup or Windows Setup/Change Network settings

           Click the Networks button
           Click Install Microsoft Windows Network.
             Choose support for additional networks (if required)
           Click OK

  You should be prompted for your network adapter - select the appropri­
  ate one. If you are not prompted, then

            Click the Adapter button
                select an adapter (say NE2000)
                Click OK
            Click the Protocol button
                select the MS TCP/IP-32 protocol
                click OK

  You will now be prompted to configure the TCP/IP protocol stack. You
  can always reconfigure this by highlighting the TCP/IP protocol shown
  in the box Adapters and clicking the Setup button.

     In the IP address box enter 172.17.0.5
     In the Subnet Mask box enter 255.255.255.0
     Enter your gateway (router) address in the box default gateway
       as 172.17.0.254

  Click OK. The computer will ask you to restart. Do so. You should now
  be able to use the Browser to connect to your HTTP Server.

  12.4.2.  Windows 95

  This section explains how to install the 32bit client for Microsoft on
  Win95. Firstly you must install the following

          Client for Microsoft Networks
          Microsoft TCP/IP Protocol
          Network Adapter

  To install these items, click on My Computer, Control Panel, Networks.
  Click Add. You will now be in a window that displays Client, Adapter,
  Protocol and Service.  To install the Client for Microsoft Networks:

         1. DoubleClick on Client
         2. Click on Microsoft
         3. DoubleClick on Client for Microsoft Networks

  To install the TCP/IP Protocol:

         1. DoubleClick on Protocol
         2. Click on Microsoft
         3. DoubleClick on TCP/IP

  Windows 95 by default installs several protocols automatically. Remove
  them by clicking on them and clicking the Remove button. Typically
  Win95 installs the Microsoft NetBeui protocol.

  To setup TCP/IP click on TCP/IP, click on Properties, click on the tab
  IP address

         Enter your IP address in the "Specify an IP address "
                               box as 172.17.0.5
         In the Subnet Mask box enter 255.255.255.0

  select the tab Gateway

    Enter your gateway (router) address in the box New gateway
       as 172.17.0.254
    Click the Add button

  The gateway address should now appear under the installed gateways
  box. Now Click OK.

  You should get a message to reboot. Do so. You should now be able to
  use the Browser to connect to your HTTP Server.

  12.4.3.  Windows NT

  This section details how to Install the TCP/IP client for WinNT 4.0.
  Start Control Panel/ Network

           Select the Adapter tab.
               Click Add to add a new adapter (if you don't have one)

  You should be prompted for your network adapter - select the appropri­
  ate one. To add the protocols.

           Select the Protocols tab
               Click Add
               Select the TCP/IP protocol
               Click OK

  You will now be prompted to configure the TCP/IP protocol stack. You
  can always reconfigure this by highlighting the TCP/IP protocol and
  clicking the Properties button.

          Select the tab IP Address
             Mark the checkbox 'Specify an IP address'
             In the IP address box enter 172.17.0.5
             In the Subnet Mask box enter 255.255.255.0
             Enter your gateway (router) address in the box Default Gateway
                 as 172.17.0.254

  Click OK. The computer will ask you to restart. You can now use any
  Browser to connect to your HTTP Server.

  12.5.  Setup TCP/IP on Macintosh

  If you are using the Macintosh for accessing your network, then this
  section details how to install MacTCP for the PowerMacs.

  Note: To enable you to refer to the Linux server as
  http://linux.mydomain/ instead of http://172.16.0.1/ in the WWW
  browser and all your intranet commands you need to edit the hosts
  file. The format of the hosts file is different from the one used in
  Unix. The Mac hosts file is based on RFC-1035. You can add more
  entries for each of your other hosts (Netware, Unix, WinNT) as well.
  The MacOS  keeps its HOSTS file in the Preferences folder under the
  System folder. Edit this file and add a line for your Linux server as:

         linux.mydomain    A  172.16.0.1

         netware.mydomain  A  172.16.0.2
         winNT.mydomain    A  172.16.0.3
         ws_1              A  172.16.0.5

  12.5.1.  MacTCP

  This section explains how to install MacTCP. Firstly you must download
  the MacTCP files from Apple or install it from the Internet Connection
  CD.  To configure MacTCP, click the Apple Menu/ Control Panels/
  TCP/IP. In the screen change the setting for 'Connect via:' to
  'Ethernet'

  Change the 'Configure' setting to 'Manually'

         In the IP address box enter 172.17.0.5
         In the Subnet Mask box enter 255.255.255.0
         Enter your gateway (router) address in the box
           Router address as 172.17.0.254

  Click OK. You should now be able to use the Browser to connect to your
  HTTP Server.

  13.  Setting up the Intranet

  An Intranet cannot be complete without sharing the resources on the
  different platforms. You will need support for other filesystems, so
  that you can access the data available on them. This document provides
  instructions to connect Linux to the following popular filesystems.

  ·  ``NCP filesystem for Netware''

  ·  ``SMB filesystem for Windows''

  ·  ``NFS filesystem for Unix''

  These filesystems can be compiled into the Linux kernel or added as
  modules, depending on the version of Linux. If you are not familiar
  with compiling the kernel you can refer to the Kernel HOWTO
  http://sunsite.unc.edu/mdw/HOWTO/Kernel-HOWTO.html and the Module
  HOWTO http://sunsite.unc.edu/mdw/HOWTO/Module-HOWTO.html for compiling
  the kernel with modules.

  13.1.  NCPFS

  To share the files on the Netware server you will need support for NCP
  (ncpfs). NCPFS works with kernel version 1.2.x and 1.3.71 upwards. It
  does not work with any earlier 1.3.x kernel. It cannot access the NDS
  database in Netware 4.x, but can make use of the bindery. If you are
  using Netware 4.x you can enable bindery support for specific
  containers using the command Set Bindery Context at the console as:

         set Bindery Context = CORP.MYDOM;WEBUSER.MYDOM

  In the above example two containers have bindery support enabled.

  You will need to download the NCP filesystem utilities using the URL
  ftp://sunsite.unc.edu/pub/Linux/system/filesystems/ncpfs/ncpfs.tgz
  (currently ncpfs-2.0.10) from Sunsite.

  13.1.1.  Installation

  To install the ncpfs utilities, type

          zcat ncpfs.tgz | tar xvf -

  to expand the files into its own directory. In this case you will get
  a directory ncpfs-2.0.10 Change your directory to this ncpfs directory
  before proceeding with the installation. Read the README and edit the
  Makefile if necessary.

  The installation of ncpfs depends on the kernel version you are using.
  For kernel 1.2, you should simply type 'make'. Subsequently typing
  'make install' will install the executables and man pages.

  If you use Kernel 1.3.71 or later, you might have to recompile your
  kernel. With these kernels, the kernel part of ncpfs is already
  included in the main source tree. To check if the kernel needs to be
  recompiled type

          cat /proc/filesystems

  It should show you a line saying that the kernel knows ncpfs.

  If ncpfs is not there, you can either recompile the kernel or add
  ncpfs as a module. For recompiling the kernel you should type 'make
  config' and when it asks you for

  The IPX protocol (CONFIG_IPX) [N/y/?]

  simply answer 'y'. Probably you do not need the full internal net that
  you are asked for next. Once the kernel is successfully installed,
  reboot, check /proc/filesystems and if everything is OK proceed with
  the installation of the ncpfs utilities. Change directory to the
  location holding your downloaded ncpfs files, and type 'make'. After
  the compilation is finished type 'make install' to install the various
  utilities and man pages.

  13.1.2.  Mounting NCPFS

  To check the installation type

          ipx_configure --auto_interface=on --auto_primary=on

       ....wait for 10 seconds and type

          slist

  You should be able to see a list of your Netware servers. Now we are
  ready to share files from the Netware server.

  Suppose we need to access HTML files from directory \home\htmldocs on
  volume VOL1: on the server MYDOM_NW, I recommend that you create a new
  user (say) 'EXPORT' with password 'EXP123' on this server to whom you
  grant appropriate access rights to this directory using SYSCON or
  NWADMIN.

  On the Linux machine create a new directory /mnt/MYDOM_NW. Now type
  the command

          ncpmount -S MYDOM_NW -U EXPORT -P EXP123 /mnt/MYDOM_NW

  to mount the netware file system. Typing the command

          ls /mnt/MYDOM_NW/vol1/home/htmldocs

  will show you a list of all the files in MYDOM_NW/VOL1:\HOME\HTMLDOCS
  (using Netware file notation). If you have any problems please read
  the IPX HOWTO at http://sunsite.unc.edu/mdw/HOWTO/IPX-HOWTO.html for
  more insights into the IPX system.

  13.2.  SMBFS

  To share the files on the Windows server you will need support for SMB
  (smbfs).

  You will need to download the SMB filesystem utilities from
  ftp://sunsite.unc.edu/pub/Linux/system/filesystems/smbfs/smbfs.tgz
  (currently smbfs-2.0.1) from Sunsite.

  13.2.1.  Installation

  To install the smbfs utilities, type

          zcat smbfs.tgz | tar xvf -

  to expand the files into its own directory. In this case you will get
  a directory smbfs-2.0.1 Change your directory to this smbfs directory
  before proceeding with the installation. Read the README and edit the
  Makefile if necessary.

  The installation of smbfs depends on the kernel version you are using.
  For kernel 1.2, you should simply type 'make'. Subsequently typing
  'make install' will install the executables and man pages.

  If you use Kernel 2.0 or later, you might have to recompile your
  kernel. With these kernels, the kernel part of smbfs is already
  included in the main source tree. To check if the kernel needs to be
  recompiled type

          cat /proc/filesystems

  It should show you a line saying that the kernel knows smbfs.

  If smbfs is not there, you can either recompile the kernel or add
  smbfs as a module. For recompiling the kernel you should type 'make
  config' and when it asks you for adding SMB filesystem support simply
  answer yes. Once the kernel is successfully installed, reboot, check
  /proc/filesystems and if everything is OK proceed with the
  installation of the smbfs utilities. Change directory to the location
  holding your downloaded smbfs files, and type 'make'. After the
  compilation is finished type 'make install' to install the various
  utilities and man pages.

  13.2.2.  Mounting SMBFS

  In our example let us assume that the WinNT server is called
  'MYDOM_NT' and is sharing its directory C:\PUB\HTMLDOCS with a share
  name of 'HTMLDOCS' without a password. On the Linux machine create a
  new directory /mnt/MYDOM_NT. Now type the command

          smbmount //MYDOM_NT/HTMLDOCS /mnt/MYDOM_NT -n

  to mount the SMB (windows share) file system. If this does not work
  try

          smbmount //MYDOM_NT/COMMON /mnt/MYDOM_NT -n -I 172.16.0.3

  Typing the command

          ls /mnt/MYDOM_NT

  will show you a list of all the files in bsol;bsol;MYDOM_NT\PUB\HTML­
  DOCS (using Windows file notation).

  13.3.  NFS

  First you will need a kernel with the NFS file system either compiled
  in or available as a module.

  Suppose you have a Unix host running NFS with the name MYDOM_UNIX and
  an IP address of 172.16.0.4. You can check the directories that are
  being exported (shared) by this host by typing the command

          showmount -e 172.16.0.4

  Once we know the exported directories you can mount them by entering a
  appropriate mount command. I recommend that you create a subdirectory
  under '/mnt' (say) 'MYDOM_UNIX' and use that as your mount point.

          mount -o rsize=1024,wsize=1024 172.16.0.4:/pub/htmldocs /mnt/MYDOM_UNIX

  The rsize and wsize may have to be changed depending on your environ­
  ment.

  If you have any problems please read the NFS HOWTO at
  http://sunsite.unc.edu/mdw/HOWTO/NFS-HOWTO.html for more insights into
  the NFS system.

  14.  Accessing the Web

  Now that we have setup the HTTP server, the clients and interconnected
  the Linux server with the other servers, we need to make some small
  adjustments on the Linux server to be able to access these mounted
  filesystems from the Web Browser.

  14.1.  Accessing the mounted filesystems

  To access the mounted directories in your HTML pages you have two
  methods:

  ·  Create a link in DocumentRoot (/usr/local/etc/httpd/htdocs) to
     refer to the mounted directory as

          ln -s /mnt/MYDOM_NW/vol1/home/htmldocs netware
                            or

          ln -s /mnt/MYDOM_NT    winNT
                            or

          ln -s /mnt/MYDOM_UNIX    unix

  ·  to edit the file srm.conf in your /usr/local/etc/httpd/conf
     directory and add a new alias.
         # Alias fakename realname
         Alias /icons/     /usr/local/etc/httpd/icons/

         # alias for netware server
         Alias /netware/   /mnt/MYDOM_NW/vol1/home/htmldocs/
         Alias /winNT/     /mnt/MYDOM_NT/
         Alias /unix/      /mnt/MYDOM_UNIX

  And restart your HTTPd. You can access the documents on the netware
  server by referring to them as http://linux.mydomain/netware/index.htm
  for the netware files and similar notations for the others.

  14.2.  Connecting to the Internet

  You can finally connect your Intranet to the Internet to access E-Mail
  and all the wonderful information out there. I propose to write a
  brief note on how to do this in a future revision. Detailed
  explanations are available in the ISP Hookup HOWTO from
  http://sunsite.unc.edu/mdw/HOWTO/ISP-Hookup-HOWTO.html and Diald mini
  HOWTO at http://sunsite.unc.edu/mdw/HOWTO/mini/Diald for setting up
  these connections.

  14.3.  Other uses

  The HTTP server can be used in the office to provide transparent
  access to information residing on different servers, at several
  locations and directories. The data can be simple documents in Word,
  Lotus spreadsheets, or complex databases.

  The application of this technology is being typically used as
  follows:-

  ·  Publishing corporate documents

     These documents can include newsletters, annual reports, maps,
     company facilities, price lists, product information literature,
     and any document which is of value within the corporate entity.

  ·  Access into searchable directories

     Rapid access to corporate phone books and the like. This data can
     be mirrored at a Web site or, via CGI scripts, the Web server can
     serve  as a gateway to back-end pre-existing or new applications.
     This means that, using the same standard access mechanisms,
     information can be made more widely available and in a simpler
     manner.  This means that it can be used to create an interface with
     RDBMS  like ORACLE and SYBASE for generating real-time information.
     Here is a list of links to such sites on the Web.

     - Web Access -
     http://cscsun1.larc.nasa.gov/~beowulf/db/web_access.html - CGI
     gateways - HTTP://www.w3.org/hypertext/WWW/RDBGate/Overview.html

  ·  Corporate/Department/Individual pages

     As cultures change within organistions to the point where even each
     department moves towards their own individual mission statements,
     the Intranet technology provides the ideal medium to communicate
     current information to the Department or Individual. Powerful
     search engines provide the means for people to find the group or
     individual who has the answers to the continuous questions which
     arise in the normal day-to-day course of doing business.

  ·  Simple Groupware applications

     With HTML forms support, sites can provide sign-up sheets, surveys
     and simple scheduling.

  ·  Software distribution

     Administrators can use the Intranet to deliver software and up-
     dates on-demand to users across the corporate network . This can be
     done with 'Java' which allows the creation and transparent
     distribution of objects on-demand rather than just data or
     applications. This is indeed possible more easily with the newer
     versions of Linux which has builtin support for Java.

  ·  Mail

     With the move to the use of Intranet mail products with standard
     and simple methods for attachment of documents, sound, vision and
     other multimedia between individuals, mail is being pushed further
     forward as a simple, de facto communications method. Mail is
     essentially individual to individual, or individual to small group,
     communication. Several utilities are available on the Linux
     platform to setup an E-mail system like sendmail, pop3d, imapd.

  ·  User Interface

     The Intranet technology is evolving so rapidly that the tools
     available, in particular HTML, can be used to dramatically change
     the way we interface with systems. With HTML you can build an
     Interface which is only limited by the creators imagination. The
     beauty about using Intranet technologies for this is that it is so
     simple. Clicking a hyperlink from HTML can take you to another
     page, it could ring an alarm, run a yearend procedure or anything
     else that a computer program can do.

  17.1.  O'Reilly & Associates Books

  In my humble opinion O'Reilly & Associates make the best technical
  books on the planet.  They focus mainly on Internet, Unix and
  programming related topics. They start off slow with plenty of
  examples and when you finish the book your an expert.  I think you
  could get by if you only read half of the book.  They also add some
  humor to otherwise boring subjects.

  They have great books on HTML, PERL, CGI Programming, Java,
  JavaScript, C/C++, Sendmail, Linux and much much more.  And the fast
  moving topics (like HTML) are updated and revised about every 6 months
  or so.  So visit the O'Reilly & Associates <http://www.ora.com/> web
  site or stop by your local book store for more info.

  And remember if it doesn't say O'Reilly & Associates on the cover,
  someone else probably wrote it.
