Reading the Documentation

This section describes the different methods for accessing the Internet Express documentation.

Reading Documentation Using the Administration Utility

After installation of the Secure Web Server subset (IAEAPCH), the Internet Express Documentation subset (IAEDOC), and the Internet Express Administration Utility subset (IAEADM), access the Administration utility for Internet Express main menu (see Section ) at:


where hostname.domain is the host name and domain of the system running Internet Express. Follow the documentation link from this page to read the Internet Express documentation.

Reading Documentation Using the Public Web Server

You can also read the documentation without the Administration utility by using the public Web server (if you chose to configure one) to access the documentation index page at http://hostname.domain/documents/bookshelf.html. If this URL does not work, verify that the Web server configuration file, /usr/internet/httpd/admin/conf/httpd.conf, contains the following line:

Alias /documents/ "/usr/internet/docs/IASS/"

The Internet Express documentation files are installed in the /usr/internet/docs/IASS directory.

  • You can access the Documentation Bookshelf installed on your system by entering the following URL (substituting the name of your system for hostname) in your browser:


  • You can also read the installed documentation directly from the file system using a Web browser running on the same system by using the file URL:


Reading Documentation from the Internet Express CD–ROM

You can also access the Documentation Bookshelf on the Internet Express Installation and Documentation CD–ROM from your Tru64 UNIX System or a PC. The documentation is available in the following formats:

  • HTML

  • Portable Document Format (PDF)

On a Tru64 UNIX System

To read the documentation from the Internet Express Installation and Documentation CD–ROM on an AlphaServer system, follow these steps:

  1. Log in to your system as root.

  2. Insert and mount the CD–ROM, replacing drive with the name of your CD–ROM drive:

    # mount /dev/drive /mnt

    Usually this will be:

    # mount /dev/disk/cdrom0c  /mnt
  3. In a Web browser, open the Documentation Bookshelf file by entering the following URL:

  4. Click on the book you want to open.

On a PC

To read the documentation from the Internet Express Installation and Documentation CD–ROM on a PC, follow these steps:

  1. Insert the CD–ROM into your PC's CD–ROM drive.

    The Bookshelf page is automatically displayed in your browser.

    If the Bookshelf does not appear, open the following URL, replacing drive with the letter of your CD–ROM drive:

  2. Click on the book you want to open.

Reading Reference Pages for Internet Express Components

Reference pages for Internet Express components are available in HTML format from the Internet Express Reference Pages index page. These HTML reference pages can be viewed using a Web browser.

Alternatively, you can view these reference pages from a command line in a terminal window if you modify the search path for the man command.

The man command's search path needs to include the following directories for Internet Express component reference pages:


You can specify an alternative search path when entering the man command by using the M or P option; for example:

# man -M /usr/news/man active.5

You can also define the man command's MANPATH environment variable on the command line or in a file, such as your .profile file or .login file.

For example, suppose your MANPATH environment variable was defined to be the following:


If you are using the sh or ksh shell, you could modify the MANPATH to add to the search path by adding the following:

# set MANPATH $MANPATH:/usr/internet/pgsql/man:/usr/internet/openldap/man:/usr/news/man: \

# export MANPATH

If you are using the csh shell, you would use a command line like the following:

# setenv MANPATH $MANPATH:/usr/internet/pgsql/man:/usr/internet/openldap/man: \

For details about defining reference page search paths, see man(1).

Reading the Open Source Software Component Documentation

The product kit also provides documentation (in ASCII text and HTML) for software components included with Internet Express. This documentation is located in the /usr/internet/docs directory on the system where Internet Express is installed.
