The name TCP/IP Services means both:

The name UNIX refers to the Compaq Tru64 UNIX operating system.

The following conventions are used in this manual. In addition, please note that all IP addresses are fictitious.
Ctrl/ x 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.
PF1 x 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.
[Return] 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 possibilities:
  • Additional optional arguments in a statement have been omitted.
  • The preceding item or items can be repeated one or more times.
  • Additional parameters, values, or other information can be entered.
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 text This typeface represents the introduction of a new term. It also represents the name of an argument, an attribute, or a reason.
italic text Italic text 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 TEXT Uppercase text indicates a command, the name of a routine, the name of a file, or the abbreviation for a system privilege.
Monospace text Monospace type indicates code examples and interactive screen displays.

This typeface indicates UNIX system output or user input, commands, options, files, directories, utilities, hosts, and users.

In the C programming language, this typeface identifies the following elements: keywords, the names of independently compiled external functions and files, syntax summaries, and references to variables or identifiers introduced in an example.

- A hyphen at the end of a command format description, command line, or code line indicates that the command or statement continues on the following line.
numbers All numbers in text are assumed to be decimal unless otherwise noted. Nondecimal radixes---binary, octal, or hexadecimal---are explicitly indicated.

Chapter 1
Using TCP/IP Services Management Commands

The TCP/IP Services product provides a management command interface you use to configure and manage the software. These commands let you perform the following tasks:

1.1 Entering Commands

To start the management control program, type TCPIP at the DCL prompt. For example:


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

Help is also available at the DCL prompt by typing HELP TCPIP_SERVICES.



The word command refers to commands for the TCP/IP Services software. DCL commands and UNIX commands are explicitly identified.

Table 1-1 provides guidelines for using management control program commands.

Table 1-1 Management Command Guidelines
Element Guideline
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 following examples illustrate an IP address, an Ethernet address, and a hardware address, respectively.


Default Refers to the command's behavior if optional qualifiers are omitted.
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.
Host names and IP addresses To specify a host or network name on a command line, you can enter either the host's name or the host's IP address.
Keywords You can abbreviate commands to the fewest number of characters, usually four, that identify the command. The following command lines, for example, have identical meanings:


Command examples shown in this manual are expressed using full command and qualifier names for clarity.

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, the following qualifiers are the same:


Wildcards are valid unless otherwise stated. A space between multiple elements is optional unless otherwise stated.

Numeric values Unless otherwise stated, all numeric values are decimal. Values are indicated by either a preceding equals sign (=) or a colon (:). For example:

Quotation marks On command lines, enclose the following in quotation marks when:
  • Lowercase and mixed-case names that are to be stored in a database with the exact case preserved.
  • Directory and file specifications that contain a slash (/).
  • UNIX commands entered on the DCL command line.

Consider these examples:

  1. To specify a path, enclose it in quotation marks:
    TCPIP> MAP "/usr/songbirds/canary" CANARY$DUA2:
  2. To specify host names using lowercase letters when you create a proxy entry in the database:
    _TCPIP> /HOST=("raven","crow","rook","daw")

    Note the use of the DCL command-line continuation character ( - ) that allows you to continue a long command on the next line.

  3. To specify a lowercase host name when adding the host to the hosts database, use these commands:
    TCPIP> SET HOST "eaglet" /ADDRESS =

    Note that DCL interprets all input as uppercase unless you enclose it in quotation marks. Therefore, you must use quotation marks to enter the host name in lowercase in the hosts database. To display information about a host, you can enter either uppercase or lowercase characters.

  4. Use quotes when entering a UNIX command at the DCL prompt. For example:
    $ TCPIP "ifconfig -a"
UNIX commands Follow UNIX syntax and case rules when entering UNIX commands at the TCPIP> prompt. For example, enter the ifconfig command in lowercase letters:
TCPIP> ifconfig

The following use of the ifconfig command is incorrect:


Wildcards If you specify a wildcard on a command line, you are asked for confirmation before the command executes.

You can change this default behavior with the /NOCONFIRM qualifier. For example:


VMS User_name Type User_ID Group_ID Host_name
Remove? [N]:

1.1.1 Setting Configuration Parameters

Some commands allow you to enter information in the database; others modify only the run-time parameters. Table 1-2 shows the SET commands that affect one or the other.

Table 1-2 SET Commands
Modify Permanent Database Files Modify Dynamic Memory

Note that the SET ROUTE command affects both the permanent and dynamic routing databases.

1.1.2 Modifying the Configuration Database

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

The following commands modify the configuration database:
