Internet Express Version 6.7 for Tru64 UNIX: Installation Guide

Chapter 1 Installation Overview

  Table of Contents


You can run the Internet Express installation procedure in a Web browser or on the command line. You choose the method you want to use early in the installation process. Chapter 2 explains how to use a Web browser to install Internet Express.

After completing the installation, perform some of the tests described in Chapter 3 to verify the installation. For troubleshooting information, see Chapter 4.


When run in a Web browser, the installation procedure provides links to this document for online help in HTML format.

Installation Prerequisites

For information on supported hardware configurations, see the QuickSpecs. Table 1-1 describes the minimum system configuration recommended for Internet Express Version 6.7.

Table 1-1 Minimum System Configuration Recommended for Internet Express Version 6.7

Maximum /usr file system disk spaceApproximately 1200 MB for a full installation of all components.
Memory256 MB
Operating system version Tru64 UNIX Version 5.1B and higher


Disk space and memory requirements can vary depending on your system configuration and the Internet Express subsets you install.

Most of the disk space required by the Internet Express Version 6.7 installation is in the /usr file system. Less than 400 KB is required in the / (root) file system and 1.6 MB in the/var file system, except that during the installation procedure, approximately 1 MB of extra space is temporarily used in the /var file system.

To avoid any potential installation errors or system misconfiguration, the installation procedure verifies that the required amount of swap space is available before installing each subset. Subsets will not be installed if the available swap space drops below 20 percent.

If this should happen, you can add another swap partition. (See swapon(8).) If you allow the installation procedure to switch your system to deferred (or lazy) swap mode, you can reboot the system for the swap mode to take effect. The deferred swap mode will allow you to make more efficient use of your swap space. Once the swap space problems are solved, you can rerun the installation procedure to install any chosen subsets that did not get installed earlier.

Certain Internet Express components require the Java Environment to be installed prior to the intallation of the subset. Table 1-2 shows the components and the minimum Java Environment (JAVAnnn or OSFJAVAnnn subset) required.

Table 1-2 Java Requirements for Components

ComponentSubset NameRequired Java
Internet Monitor IAEMON Java SDK 1.3.1 or later
LDAP Browser IAEOLDAP Java JRE/SDK 1.3.1 or later
Axis ServerIAESOAP Java JDK/SDK 1.3.1 or later
Axis/UDDI4J ClientsIAEXMLJLIBJava JDK/SDK 1.3.1 or later
Tomcat IAETOMCATJava JDK/SDK 1.4 or later


The JDK kit can be downloaded from the following Web site:

If Internet Express is already installed on your system, you do not need to remove it before installing Version 6.7 of the product. The Version 6.7 installation procedure updates your earlier version, preserving configuration files and user data. Updates from Versions 6.4 and 6.5 to 6.7 are supported, and updates from earlier versions should also work. (Earlier versions of this product are named Open Source Internet Solutions.)

Network and DNS Client Configuration Worksheets

If the installation procedure determines that your network or Domain Name System (DNS) is not configured on your system, the procedure does a minimal configuration based on information that you provide during the installation procedure. The worksheets in the following sections can help you gather and organize the information requested during installation to configure the network and DNS. In cases where you must obtain addresses, contact your Internet service provider (ISP) or system manager.

Network Configuration Worksheet

Use the following worksheet to gather network configuration data before installing Internet Express Version 6.5:

Type of InformationExampleEntry
Network interfacetu0 
Host name for this machinemyhost 
IP address for the network interface10.55.39.182 
Subnet mask255.255.255.0 
Default gateway IP address10.55.39.100 
Network daemons and static routingrouted -q 


If you intend to configure FireScreen after installing Internet Express to set up your system as a firewall, record the information for both network interfaces in the worksheet. Then use the sysman system management utility to configure the system as a gateway using the information from the worksheet. Enter the following command in a terminal window when logged in as root after the Internet Express installation has completed:

# /usr/sbin/sysman network 

See the Administration Guide for information on installing and configuring the FireScreen firewall.

DNS Client Configuration Worksheet

The Domain Name System (DNS) is a naming system that provides a service for resolving host names to Internet Protocol (IP) address (and vice versa). The implementation of DNS on most UNIX systems is BIND (Berkeley Internet Name Domain). BIND is a network-naming service that enables servers to name resources or objects and to share information with other objects on the network.

Use the following worksheet to gather DNS client configuration data before installing Internet Express:

Type of InformationExampleEntry
Is the system a DNS server or client?client 
Host name of primary name serverdnssrvr1 
IP address of primary name server10.55.39.186 

The Internet Express installation procedure invokes the bindconfig utility and allows you to configure a primary name server. To set up a secondary name server, invoke the bindconfig utility on the command line.

Internet Express Components and Subsets

The Internet Express product consists of Open Source Internet software, Internet Monitor, LDAP Module for System Authentication, and administration software developed by HP. All components are optional, except when required as a prerequisite to another component you selected. The installation procedure automatically selects all prerequisite components when you select a component that is dependent on other components.

The following software components are installed as part of the following Internet Express subsets. See the Software Description and Licensing Terms for a list of the current version numbers for the components.


Subset names appear in parentheses after the component name.

  • Majordomo Automated Internet Mailing Lists Server (IAEMAJD)

    Majordomo is a set of programs that automate the operation and maintenance of Internet mailing lists. Majordomo automatically handles requests to subscribe to, or unsubscribe from, mailing lists; it supports closed lists (subscription requests are sent to the list owner for approval) and moderated lists (all messages are sent to the list owner for approval before sending to subscribers). Lists that are set up under the control of Majordomo can be manipulated by electronic mail, so the list owner does not have to be on the system where Majordomo is running.

  • ProcMail Mail Filtering Language (IAEPROC)

    ProcMail is the mail processing language written by Stephen van den Berg of Germany. Using ProcMail, you can filter hundreds or thousands of incoming mail messages per day according to a predefined set of rules. Because the ProcMail utility understands details about most UNIX mail transport and delivery agents, it is the tool of choice for writing custom mail filtering scripts.

  • Sendmail Mail Transport Agent (IAESMTP)

    You can choose Sendmail as an option during installation. Sendmail is the BSD Mail Transport Agent supporting E-mail transport by means of TCP/IP using Simple Mail Transfer Protocol (SMTP).
