You might find the Internetworking with TCP/IP: Principles, Protocols, and Architecture, by Douglas Comer useful if you are looking for a comprehensive overview of the TCP/IP protocol suite.
DIGITAL TCP/IP Services for OpenVMS Version 5.0 completes the change initiated several releases ago when the product name changed from "ULTRIX Connection (UCX)" to "DIGITAL TCP/IP Services for OpenVMS." To complete this change, the identifier "UCX" is replaced with "TCPIP" in the following:
DIGITAL TCP/IP Services for OpenVMS is used to mean both:
The auxiliary server is the DIGITAL TCP/IP Services for OpenVMS implementation of the UNIX internet daemon (inetd.)
NFS is the DIGITAL TCP/IP Services for OpenVMS implementation of the NFS protocols, including the NFS server, the NFS client, and PC-NFS.
TN3270 means the TELNET client software that emulates IBM 3270 model terminals.
The term UNIX refers to DIGITAL UNIX operating system. DIGITAL UNIX is fully compatible with Version 4.3 and Version 4.4 of the Berkeley Software Distribution (BSD).
Host and node both mean a system connected to an internet.
The term Internet refers to the global interconnection of networks, as defined by RFC 1208, which consists of large networks using TCP/IP to provide universal connectivity, reaching the Defense Advanced Projects Research Internet, MILNET, NSFnet, CERN, and many worldwide universities, government research labs, military installations, and business enterprises.
The term internet refers to private interconnected networks that use TCP/IP to connect together and function as one, virtual network.
All IP addresses in this book represent fictitious addresses. The following conventions apply to this book.

Part 1 provides the information on how to get started after installing and configuring DIGITAL TCP/IP Services for OpenVMS software.
Chapter 1 includes the following topics:
Chapter 2 describes how to set up network interfaces.
Chapter 3 explains how to set up serial lines.
Chapter 4 discusses how to configure and manage network routing.
This chapter reviews information you need to get started with the DIGITAL TCP/IP Services for OpenVMS software. Topics include:
This manual assumes you installed and configured DIGITAL TCP/IP Services for OpenVMS software with the configuration procedure called TCPIP$CONFIG. This menu-driven procedure configures the software components you select or all of the TCP/IP Services software components. The "out-of-the-box" defaults are designed to get your system up and running as an internet host with minimal effort.
TCPIP$CONFIG CREATES several database files described in Table 1-1.
| Database | File Name |
|---|---|
| BOOTP database | SYS$COMMON:[SYSEXE]TCPIP$BOOTP.DAT |
| Configuration database | SYS$COMMON:[SYSEXE]TCPIP$CONFIGURATION.DAT |
| Export database | SYS$COMMON:[SYSEXE]TCPIP$EXPORT.DAT |
| Hosts database | SYS$COMMON:[SYSEXE]TCPIP$HOST.DAT |
| Networks database | SYS$COMMON:[SYSEXE]TCPIP$NETWORK.DAT |
| Proxy database | SYS$COMMON:[SYSEXE]TCPIP$PROXY.DAT |
| Routes database | SYS$COMMON:[SYSEXE]TCPIP$ROUTE.DAT |
| Services database | SYS$COMMON:[SYSEXE]TCPIP$SERVICE.DAT |
| Printcap database (used by LPR/LPD) | SYS$SPECIFIC:[TCPIP_LPD]TCPIP$PRINTCAP.DAT |
Logical names allow you to customize or modify component behavior. Logical names also point to directories, database files, and log files.
TCPIP$CONFIG defines the following logical names for the databases listed in Table 1-1.
See individual component chapters in this manual for information on how
specific components use logical names.
1.1.2 Modifying Your Configuration
After the initial configuration, you may want to reconfigure existing components or configure new ones, disable and re-enable components, add hosts, reconfigure routing, and so forth.
When making any configuration modifications, Compaq strongly recommends that you rerun the configuration procedure SYS$STARTUP:TCPIP$CONFIG1.
In some instances, TCPIP$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:
Throughout this manual, all commands are assumed to be TCP/IP Services management commands. Any DCL commands that are mentioned are identified as such.
For a full description of the management commands and a discussion of
how to use them, see the DIGITAL TCP/IP Services for OpenVMS Management Command Reference manual.
1.1.3 Saving Changes
The configuration procedure TCPIP$CONFIG saves configuration and initialization information in the file TCPIP$CONFIGURATION.DAT. You can modify the configuration database 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:
Compaq strongly recommends that you use TCPIP$CONFIG to start and stop the software. If you need to start the product manually, enter the following command:
$ @SYS$MANAGER:TCPIP$STARTUP |
The startup procedure enables the configured services and initializes the configured network interfaces.
To stop the product manually, enter the following command:
$ @SYS$MANAGER:TCPIP$SHUTDOWN |
The shutdown procedure involves these steps:
1 You cannot use TCPIP$CONFIG to set up SLIP or PPP lines. See Chapter 3 for more information. |
