Preface

The DIGITAL TCP/IP Services for OpenVMS product is Compaq's implementation of the TCP/IP networking protocol suite and internet services for OpenVMS Alpha and OpenVMS VAX systems.

A layered software product, DIGITAL TCP/IP Services for OpenVMS provides a comprehensive suite of functions and applications that support industry-standard protocols for heterogeneous network communications and resource sharing.

This manual describes the DIGITAL TCP/IP Services for OpenVMS management commands. Use it in conjunction with the DIGITAL TCP/IP Services for OpenVMS Management manual, which describes the management tasks.

Intended Audience

This manual is for experienced OpenVMS and/or UNIX system managers and assumes a working knowledge of TCP/IP networking, TCP/IP terminology, and some familiarity with the DIGITAL TCP/IP Services for OpenVMS product.

If you are not familiar with the DIGITAL TCP/IP Services for OpenVMS product, please review the DIGITAL TCP/IP Services for OpenVMS Concepts and Planning before using this manual to configure and manage TCP/IP components.

New and Changed Features

DIGITAL TCP/IP Services for OpenVMS Version 5.0 provides a new kernel based on the IPv4 kernel ported from DIGITAL UNIX Version 4.0D. ¹

Other new features include:

Dynamic Host Configuration Protocol (DHCP) that allows the system manager to provide dynamic allocation of IP addresses from a single OpenVMS host.
Gateway routing daemon (GATED) server and a comprehensive suite of interior and exterior routing protocols that offer advanced routing options.
Classless Inter-domain routing (CIDR) which allows networks to be built with variable-length subnetworks
PathMTU discovery, a mechanism that allows an IP host to determine the most efficient packet size for use on a particular path between the source to the destination host.
UNIX management utilities to assist with the management of OpenVMS systems in a mixed UNIX and OpenVMS environment.
New implementations of NTP, SNMP, and BIND.
Improved online help and a new message database for use with the OpenVMS Help Message utility (MSGHLP).

Changes to this document include:

New commands to support GATED routing: START ROUTING /GATED and SET GATED
A new command to convert existing UCX BIND configurations to BIND 8.1 format CONVERT/CONFIGURATION BIND
The removal of several obsolete commands and command/qualifier pairs. See the DIGITAL TCP/IP Services for OpenVMS Release Notes for a complete list of obsolete commands.

Note

¹ This kernel is based on the Berkeley Software Distribution (BSD) Versions 4.3 and 4.4 with enhancements from Compaq Computer Corporation.

Document Structure

This manual contains two chapters.

Chapter 1 introduces the management control program.
Chapter 2 provides command descriptions for each management command.

Terminology

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:

Registered product facility code
Management command prompt
All messages, examples, and banners
All product file names and databases
All logical names, except those retained for compatibility
All associated product documentation

DIGITAL TCP/IP Services for OpenVMS is used to describe both:

DIGITAL TCP/IP Services for OpenVMS Alpha
DIGITAL TCP/IP Services for OpenVMS VAX

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 the 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.

Chapter 1
Using TCP/IP Services Management Commands

DIGITAL TCP/IP Services for OpenVMS software provides a management command interface you use to configure, reconfigure, and manage the software. These commands let you perform the following tasks:

Modify parameters, usually to tune performance
Configure customer-developed services
Enable components that you originally opted not to run
Disable running components
Monitor the software
Customize a site-specific startup file

1.1 Entering Commands

To start the management control program, type TCPIP at the OpenVMS prompt.

$ TCPIP

At the TCPIP> prompt, enter the commands described in this manual or display online help. Type EXIT to exit the management control program or Ctrl/C to abort a command.

Help is also available at the OpenVMS prompt by entering HELP TCPIP_SERVICES.

Note

The word command refers to commands for the DIGITAL TCP/IP Services for OpenVMS product. DCL commands and UNIX commands are so identified when needed.

Table 1-1 describes the guidelines you should follow when entering management control program commands.

Table 1-1 Command Guidelines
Guideline Description

Abbreviating Keywords Abbreviate command keywords to the fewest number of characters, usually four, that identify the command.

Using Quotation Marks On command lines, enclose the following in quotation
marks ( " " ):

Lowercase and mixed-case names to be stored in a database with the exact case preserved.
Directory and file specifications with a slash ( / ).

Consider these examples:
TCPIP> MAP "/usr/songbirds/canary" CANARY$DUA2:
TCPIP> ADD PROXY COUSINS /GID=10 /UID=40 /NFS=OUTGOING -
_TCPIP> /HOST=("raven","crow","rook","daw","magpie")
TCPIP> SET HOST "eaglet" /ADDRESS = 128.33.22.1
TCPIP> SHOW HOST EAGLET

Entering Host Names and IP Addresses To specify a host or network on a command line, you can enter either the host's name or the host's IP address.

File and Directory Names When you specify OpenVMS files, follow all OpenVMS file specification rules. Likewise, when you specify UNIX files, follow all UNIX file specification rules.

Multiple Values To specify multiple host names, addresses, or options for parameters and qualifiers, be sure to separate elements with commas and enclose the entire list in parentheses.
Wildcards are valid unless otherwise stated. A space between multiple elements is optional unless otherwise stated. For example,
/qualifier=(option_a:value1,option_b:value2,value3)

is the same as
/qualifier=(option_a=value1),(option_b=value2,value3)

Number Values Unless otherwise stated, all shown values are decimal.

Address Formats Some commands require that you specify one of the following kinds of addresses:

IP
Ethernet
FDDI
Token Ring
Hardware

Be sure to use the appropriate format. The examples below illustrate an IP address, a hardware address, and an Ethernet address.
TCPIP> SET HOST CROW /ADDRESS=1.2.3.4
TCPIP> SET BOOTP MACAW -
_TCPIP>/HARDWARE=ADDRESS=08-dd-ff-2a-23-21
TCPIP> SET ARP AA-BB-04-05-06-07 CONDOR

UNIX commands Follow UNIX syntax and case rules when entering UNIX commands at the TCPIP> prompt. For example, enter:
TCPIP> ifconfig options

not
TCPIP> IFCONFIG options

Using Wildcards If you specify a wildcard on a command line, you will be asked for confirmation before the command executes.
Change this default behavior with the /NOCONFIRM qualifier. For example:
TCPIP> REMOVE PROXY GRACKLE /GID=* /UID=130
VMS User_name Type User_ID Group_ID Host_name
GRACKLE N 269 48 MAPLE
Remove? [N]:

Most SHOW commands default values to *.
DELETE commands require that you supply a parameter.

Valid Values Most management commands accept any number value you might enter. Specify values appropriate to your environment.

1.1.1 Setting Configuration Parameters

For some components, you can enter information only in a permanent database and, for others, only in dynamic memory. In addition, DIGITAL TCP/IP Services for OpenVMS can store parameter settings and other configuration information for some of the software in both locations. Table 1-2 shows the SET commands that affect only one or the other.

Table 1-2 Setting Configuration Parameters
Modify Permanent Database Files Modify Dynamic Memory

SET BOOTP SET ARP

SET CONFIGURATION SET COMMUNICATION

SET HOST SET INTERFACE

SET MX_RECORDS SET NAME_SERVICE

SET NETWORK SET NFS_SERVER

SET CONTAINER SET PROTOCOL

SET SERVICE

The SET ROUTE command works on both the permanent and dynamic routing databases.

1.1.2 Modifying Parameters

Unlike the other databases, which have similar objects, the configuration database holds diverse initialization information for various DIGITAL TCP/IP Services for OpenVMS components.

All the initialization information is node-specific except for TIME and SNMP. This information is identified by the SYSGEN parameter SCSNODE. If you change your node's name after you configure DIGITAL TCP/IP Services for OpenVMS, the startup information, by default, will not be seen by the startup procedure or by the management software.

To see the configuration that is paired to the original node name, use the /ON qualifier, which is available with all the configuration commands. To copy node-specific startup information from one node to another, use the COPY CONFIGURATION command.

The following commands modify the configuration database:

SET CONFIGURATION BIND
SET CONFIGURATION COMMUNICATION
SET CONFIGURATION ENABLE SERVICE
SET CONFIGURATION INTERFACE
SET CONFIGURATION NAME_SERVICE
SET CONFIGURATION PROTOCOL
SET CONFIGURATION SMTP
SET CONFIGURATION SNMP
SET CONFIGURATION START ROUTING
SET CONFIGURATION TIME

1.1.3 Creating and Deleting Files

The CREATE commands create the following kinds of files:

Database files
Compaq strongly recommends that you run the DIGITAL TCP/IP Services for OpenVMS configuration procedure instead of manually creating databases. See DIGITAL TCP/IP Services for OpenVMS Installation and Configuration for instructions.
Use the following commands to create database files:
- CREATE BOOTP
- CREATE CONFIGURATION
- CREATE EXPORT
- CREATE HOST
- CREATE NETWORK
- CREATE PROXY
- CREATE ROUTE
- CREATE SERVICE
UNIX style container directories
These directories are used by the NFS server software. Create and delete container directories and files with the following commands:
- CREATE CONTAINER, DELETE CONTAINER
- CREATE DIRECTORY, REMOVE DIRECTORY, REMOVE FILE
