Conventions

The name TCP/IP Services means both:

The name UNIX refers to the Tru64 UNIX operating system.

All IP addresses are fictitious.

The following conventions are used in this manual.
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 type Bold type represents the introduction of a new term. It also represents the name of an argument, an attribute, or a reason.
italic type 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 Uppercase type indicates a command, the name of a routine, the name of a file, or the abbreviation for a system privilege.
Example This typeface indicates code examples, command examples, and interactive screen displays. In text, this type also identifies URLs, UNIX commands and pathnames, PC-based commands and folders, and certain elements of the C programming language.
- 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
Getting Started

TCP/IP is an open communications standard that enables any connected host to communicate with any other connected host. The TCP/IP Services software is the HP OpenVMS implementation of industry-standard TCP/IP networking protocols.

The TCP/IP Services software allows you to communicate and share resources with remote OpenVMS systems, UNIX systems, and other systems that support the TCP/IP protocol suite.

The product consists of a number of components that implement various TCP/IP protocols. These components provide remote computing, file transfer, resource sharing, electronic mail, and network services as follows:

Table 1-1 TCP/IP Components
Remote Computing
FINGER Display information about users logged in to a remote host, such as their login user names or programs they are using.
RCP Copy files between the local host and a remote host or between two remote hosts. Requests are authenticated on the remote host or hosts using the user name supplied by RCP.
RLOGIN Connect to a remote host, which starts an interactive login session. Requests are authenticated on the remote host using the user name supplied by RLOGIN.
RMT/RCD Access magnetic tape and CD drives on a remote host as though they are available locally.
RSH Connect to a remote host, which executes the command you specify. Requests are authenticated on the remote host using the user name supplied to RSH.
RSH/PASSWORD Use the REXEC facility to connect to the remote host, which executes the command you specify. Requests are authenticated on the remote host using the user name and password supplied by RSH.
RMT/RCD Access magnetic tape and CD drives on a remote host as though they are available locally.
TELNET Log in to a remote host in a network using various options to customize the session, control output from the remote host, and negotiate compatibility differences. To start a TELNET session, enter the following command:
$ TELNET

File Transfer
FTP Create, delete, and copy files and directories between hosts. To start an FTP session, enter the following command:
$ FTP

TFTP Transfer files using the UDP protocol and no authentication. Typically used during the bootstrap process of diskless systems.
Resource Sharing
LPD/LPR Print files on remote and local hosts.
NFS Authenticate requests and provide access to remote files.
TELNETSYM Print files on remote hosts using the TELNET protocol.
Electronic Mail
IMAP View, move, copy, and delete electronic mail from your PC, and in conjunction with SMTP, create and send mail.
POP Send and receive electronic mail from your PC.
SMTP Send and receive electronic mail from remote hosts.
Programming Utilities
MIBCOMP Compile SNMP subagent source files in ASN.1 format.
RPCGEN Create programming skeletons that implement the RPC mechanism.
Network Services
BIND Name and address resolution service to distribute and manage host information.
BOOTP Answer bootstrap requests from remote devices.
DHCP Configure and maintain your IP address space including the temporary assignment of IP addresses.
Management commands Manage your TCP/IP environment. To start the management control program, enter the following command:
$ TCPIP

For online descriptions of the management commands, enter the following command:

$ TCPIP HELP

NSLOOKUP Determine if your local name server is running correctly or retrieve information from remote servers.
NTP Synchronize time between hosts.
PPP Connect a node to a network using IP or other supported network protocols.
SLIP, CSLIP Connect a node to a network over a serial connection using IP.
SNMP Monitor and manage network devices from across an internetwork.
TCPDUMP Analyze dumps and capture packets.
TCPTRACE Trace packets going in and out of the system.

Your particular installation may include some or all of the above components. For information about the components available to you, see your system or network manager.

System or network managers are generally authorized to install, configure, and manage the various TCP/IP components on your system. And, as such, many of the TCP/IP components are used primarily by system or network managers and are seldom needed by TCP/IP users. You can find the details of system management components and commands in the HP TCP/IP Services for OpenVMS Management guide and the HP TCP/IP Services for OpenVMS Management Command Reference manual.

If you are a TCP/IP user and want to manipulate files on remote systems, send and receive electronic mail, log in to remote systems, or enter commands remotely, this user guide provides the information and commands you need.
