Internet Express for Tru64 UNIX Version 6.8 Installation Guide (14234)

http://h18010.www1.hp.com/java/download/index.html
If Internet Express is already installed on your system, you do not need to remove it before
installing Version 6.8 of the product. The Version 6.8 installation procedure updates your earlier
version, preserving configuration files and user data. Updates from Versions 6.4 and 6.5 to 6.8
are supported, and updates from earlier versions should also work. (Earlier versions of this
product are named Open Source Internet Solutions.)
1.2 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.
1.2.1 Network Configuration Worksheet
Use the following worksheet to gather network configuration data before installing Internet
Express Version 6.5:
EntryExampleType of Information
tu0
Network interface
myhost
Host name for this machine
10.55.39.182
IP address for the network interface
255.255.255.0
Subnet mask
10.55.39.100
Default gateway IP address
routed -q
Network daemons and static routing
Note:
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.
1.2.2 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.
