The name TCP/IP Services means:
The name UNIX refers to the HP Tru64 UNIX operating system.
The following conventions are used in this manual. In addition, please note that all IP addresses are fictitious.
|A sequence such as Ctrl/ x indicates that you must hold down the key labeled Ctrl while you press another key or a pointing device button.
|A sequence such as PF1 x indicates that you must first press and release the key labeled PF1 and then press and release another key or a pointing device button.
In examples, a key name enclosed in a box indicates that you press a
key on the keyboard. (In text, a key name is not enclosed in a box.)
In the HTML version of this document, this convention appears as brackets, rather than a box.
A horizontal ellipsis in examples indicates one of the following
|A vertical ellipsis indicates the omission of items from a code example or command format; the items are omitted because they are not important to the topic being discussed.
|In command format descriptions, parentheses indicate that you must enclose choices in parentheses if you specify more than one.
|In command format descriptions, brackets indicate optional choices. You can choose one or more items or no items. Do not type the brackets on the command line. However, you must include the brackets in the syntax for OpenVMS directory specifications and for a substring specification in an assignment statement.
|In command format descriptions, vertical bars separate choices within brackets or braces. Within brackets, the choices are optional; within braces, at least one choice is required. Do not type the vertical bars on the command line.
|In command format descriptions, braces indicate required choices; you must choose at least one of the items listed. Do not type the braces on the command line.
|Bold type represents the introduction of a new term. It also represents the name of an argument, an attribute, or a reason.
|Italic type indicates important information, complete titles of manuals, or variables. Variables include information that varies in system output (Internal error number), in command lines (/PRODUCER= name), and in command parameters in text (where dd represents the predefined code for the device type).
|Uppercase type indicates a command, the name of a routine, the name of a file, or the abbreviation for a system privilege.

Part 1 provides the information on how to get started after installing and configuring the TCP/IP Services software.
Part 1 includes the following chapters:
This chapter reviews information you need to get started with the TCP/IP Services software. Topics include:
This manual assumes you installed and configured TCP/IP Services software with the configuration procedure SYS$MANAGER:TCPIP$CONFIG.COM, as described in the HP TCP/IP Services for OpenVMS Installation and Configuration manual. This menu-driven procedure configures the software components you select or all of the TCP/IP Services software components. The "out-of-the-box" defaults are designed to get your system up and running as an internet host with minimal effort.
TCPIP$CONFIG creates the database files listed in Table 1-1.
Logical names allow you to customize or modify component behavior. Logical names also point to directories, database files, and log files.
TCPIP$CONFIG defines the following logical names for the databases listed in Table 1-1:
Service-specific logical names should be defined while the service is not running. Always stop the service before defining logical names.
Most logical names require SYSTEM privileges in order to affect the service. You should use the /EXECUTIVE and /SYSTEM qualifiers on the DEFINE command line.
It is important to always use the standard, documented shutdown procedures to stop the services and to stop TCP/IP Services; otherwise, logical names may revert to their default definitions.
Many services reference service-specific configuration files. To specify different configuration options for the nodes in an OpenVMS cluster, you can modify service-specific logical name so that the configuration files are specific to each node. In clusters with a shared system disk, the default device (SYS$SYSDEVICE) is a cluster-common directory.
To specify node-specific configuration files, you can define the service-specific logical to reference a node-specific file. For example, on each node that requires node-specific customizations:
$ DEFINE/SYS/EXEC logical-name SYS$SPECIFIC:[directory]logical-name
See individual component chapters in this manual for information on how
specific components use logical names.
1.1.2 Modifying Your Configuration
After the initial configuration, you may want to reconfigure existing components or configure new ones, disable and re-enable components, add hosts, reconfigure routing, and so forth.
When making any configuration modifications, HP recommends that you run the configuration procedure TCPIP$CONFIG again.
You cannot use TCPIP$CONFIG to set up SLIP or PPP lines. See Chapter 3 for more information.
In some instances, TCPIP$CONFIG only partially configures a component (for example, when configuring a BIND name server). You may need to run additional setup programs or enter management commands to complete the configuration and fine-tune your environment.
Component-specific chapters in this manual describe additional configuration tasks and explain how to configure and manage specific components. These tasks may include:
The configuration procedure TCPIP$CONFIG saves configuration and initialization information in the file TCPIP$CONFIGURATION.DAT. You can modify the configuration dynamically or permanently, as follows:
To make changes take effect immediately and modify permanent settings, enter both the interactive SET and permanent SET CONFIGURATION commands.
The following commands permanently modify the configuration database:
Throughout this manual, all commands are assumed to be TCP/IP management commands. Any DCL commands that are mentioned are identified as such.
For a full description of the TCP/IP management commands and a discussion of how to use them, see the HP TCP/IP Services for OpenVMS Management Command Reference manual.
