DESCRIPTION
The Digital TCP/IP Services for OpenVMS product is a layered software
product that provides interoperability and resource sharing between
OpenVMS systems, UNIX[R] systems, and other systems that support the
TCP/IP Protocol Suite and Sun[R] Microsystems' NFS[TM].
The Digital TCP/IP Services for OpenVMS (TCP/IP) product provides network
file access, remote terminal access, remote command execution,
remote printing, mail, and application development.
A lower cost version of the Digital TCP/IP Services for OpenVMS product,
identified as a client, is available for users who do not require
the full complement of features available in the Digital TCP/IP
Services for OpenVMS product. The client license includes all of the
functionality of the server license with the exception that the following
server components are not included when the client license is purchased:
NFS Server, BIND Server, PC-NFS Server, and the remote BOOT Server.
Customers requiring any of those server functions should purchase the
server license. A Digital TCP/IP Client Upgrade license is also avail-
able in case the full product is required after initial purchase of
a client-only license.

NEW FEATURES
IP/Multicasting
Allows users to participate in multicast messaging, including the use
of the multicast backbone of the Internet. Saves bandwidth by limit-
ing the number of messages that must be sent.
Dynamic Load Balancing-DNS based
Ensures the work load is evenly distributed across all hosts in a clus-
ter, ensuring optimum response times for users.
RLOGIN Proxy
Provides proxy access to systems so that a host_name:user_name com-
bination can attach directly to a target system without going through
user_name:password interaction when the connection is established.
RCP-Remote Copy Procedure
Allows users to remotely copy files from any system in a network to
any other system in the network as though the files were local files.
Outbound Telnet
Allows system managers to permanently create TN device names connected
to remote devices.
OpenVMS Integration
Provides easier access to TCP/IP functions using OpenVMS DCL commands.
2
RPC/RPCGEN
RPC enables customers to run procedures on remote systems using the
latest SUN[TM] RPC libraries. RPCGEN enables customers to automati-
cally generate RPC calls.
OpenVMS 64-Bit Support
Provides users with the capability to run on 64-bit OpenVMS V7.0.
Features
Installation and Configuration
The Digital TCP/IP Services for OpenVMS V4.0 product is installed with
VMSINSTAL for VAX computer systems, or with the POLYCENTER Software
Installation (PCSI) utility for Alpha computer systems.
For configuration ease, the Digital TCP/IP Services for OpenVMS product
provides a menu-driven configuration procedure. This procedure enables
you to configure only those services and applications that you
use. It also enables you to configure all client software components
quickly without selecting individual menu options.
Communications
Communications are based on the 4.3 Berkeley Software Distribution,
implementing the following protocols and features:
o Transmission Control Protocol (TCP)
o Internet Protocol (IP)
o Internet Control Message Protocol (ICMP)
o Address Resolution Protocol (ARP)
o User Datagram Protocol (UP)
o Routing Information Protocol (RIP)
o Ethernet support
3
o FDDI support
o Auxiliary (AUX) Server (united), plus enhancements such as security
and event logging
Fiber Distributed Data Interface (FDDI) Support
FDDI is an ANSI standard for a network technology based on fiber optics.
It specifies a 100-megabit-per-second transmission rate. Digital
TCP/IP Services for OpenVMS allows OpenVMS systems to take advantage
of this technology by enabling TCP/IP communications with other
hosts in these configurations:
o On the same FDDI network
o Over a FDDI/Ethernet bridge
o Over a router
OpenVMS hosts are also able to act as an Internet gateway between FDDI
networks and one or more Ethernets.
The management of the FDDI controller is integrated with the TCP/IP
network management interface.
Auxiliary Server (United)
The united software is the TCP/IP service dispatcher for UNIX systems
which was first provided by Berkeley Software Distribution (BSD) 4.3.
This feature significantly simplifies the writing of applications and
manages overhead by reducing the number of simultaneous server
processes on the system.
The Digital TCP/IP Services for OpenVMS implementation of united:
o Listens for incoming connection requests and appropriately starts
application services. It controls dynamic process creation in the
same manner as the UNIX-based united.
o Provides a Services Database.
o Provides security features.
4
o Offers event logging.
BIND Server
Translates Domain Name System host names to IP addresses. Network managers
set up a BIND database to configure primary, secondary, and caching
servers on OpenVMS hosts. This complements the BIND resolver, the client
part of BIND that requests nodename-to-address translations from a BIND
server.
Remote Booting
Remote host booting of diskless clients using OpenVMS as the boot server.
This feature uses the BOOTP and TFTP Protocols to initiate the boot
request and to download the boot files.
UCX Management with Command-line Interface
UCX Management provides DCL-style commands to control and monitor the
UCX software components.
Simple Network Management Protocol (SNMP) Agent
SNMP is the internet standard protocol for network management over TCP/IP.
The SNMP agent communicates with network management directors to
provide information about network activity. MIB II variables are
supported within SNMP.
Security and Network Access Control
System managers use network security features to control the
accessibility to OpenVMS systems from remote Internet hosts.
Application Programming Interfaces
Digital TCP/IP Services for OpenVMS V4.0 includes the following
appplication programming interfaces:
- C socket programming interface
Provides the Berkeley socket programming interface to develop
TCP/IP networking applications in the C language.
5
- QIO programming interface
Provides a QIO programming interface to develop TCP/IP networking
applications in any OpenVMS language.
- SRIQIO interface
Provides emulation of the SRIQIO interface.
- Sun RPC, with XDR and Portmapper
Sun[R] Remote Procedure Calls (Sun RPC) are included in the UCX pro-
gramming interface. The Sun RPC library includes a library of RPC
function calls, the Portmapper module, and external Data Represen-
tation (XDR) routines.
Applications
This component includes the widespread end-user protocols for file
transfer, remote login, remote command processing, remote printing, and mail
exchange.
o File Transfer Protocol (FTP)
FTP is the internet application protocol for file transfer. It enables
users to transfer files to and from remote hosts.
o Telnet
Telnet is the internet application protocol for remote login. It enables
OpenVMS users to log into remote systems and remote users to log
into OpenVMS systems.
Telnet provides support for both character and line modes. It also
enables users to activate multiple Telnet sessions.
o Telnet 3270
Telnet 3270 enables users to make Telnet connections from OpenVMS sys-
tems to remote IBM[R] systems using a 3270-style terminal interface.
o Berkeley Remote Commands (rlogin, rsh, rexec)
Digital TCP/IP Services for OpenVMS implements the popular UNIX remote
login (rlogin), remote shell (rsh), and remote executive (rexec)
services.
6
Like Telnet, remote login (rlogin) enables users to log into remote
systems and remote users to log into OpenVMS systems.
Rsh enables OpenVMS users to execute commands on remote systems and
remote users to execute DCL commands on OpenVMS systems. Authentication
is based on either user password or proxy access.
o Remote printing
Digital TCP/IP Services for OpenVMS provides the following remote print-
ing services:
OpenVMS users can issue DCL-style PRINT commands to print files on remote
systems using the LPD protocol.
Similarly, remote users can print files on OpenVMS systems using the
LPD protocol.
OpenVMS users can also use the TELNET Print Symbiont to print files
on remote systems.
o Simple Mail Transfer Protocol (SMTP)
SMTP is the internet application protocol for mail. Users can send and
receive electronic mail to and from remote hosts.
Network File System
The NFS[TM] software supports the Network File System (NFS) V2.0 protocol
specifications. NFS is an application layer protocol that provides
clients with transparent access to remote file services.
The NFS server software promotes data sharing among clients by providing
a central data storage facility for OpenVMS and UNIX files. The
NFS server software provides two types of file access for remote clients:
o Access to OpenVMS files
o Access to files that are compatible with the UNIX Operating System.
7
Automount
As implemented in Digital TCP/IP Services for OpenVMS, the NFS AUTO-
MOUNT command transparently mounts and unmounts NFS file systems on
an as-needed basis, which is especially useful for mounting file systems
and directories that are occasionally needed.
File Conversion On-The-Fly
Maximizes interoperability between OpenVMS and other systems utilizing
the NFS protocol by providing a sequential "read on-the-fly" file
conversion capability.
PC-NFS Server
Remote PC users mount and access NFS files from OpenVMS. UID/GID iden-
tification and authentication of the remote PC user is established through
the use of the UCX Proxy Database. Once access is established, users
can print via the PC-NFS printing mechanism.
PATHWORKS Integration
Digital TCP/IP Services for OpenVMS V4.0 supports the PATHWORKS IP driver
for improved PATHWORKS and TCP/IP integration. (Requires PATHWORKS Version
5 series.)
