HP TCP/IP Services for OpenVMS Version 5.6
HP TCP/IP Services for OpenVMS Version 5.6 SPD 46.46.21
• DHCP dynamically updates BIND using a feature that
allows DHCP clients to be configured with a regis-
tered name. DHCP uses this name to assign an
address when it updates the BIND database. In ad-
dition, this release offers both a DHCP client and
server, which provides a centralized approach to the
configuration and maintenance of IP address space.
With DHCP server, the system manager can pro-
vide dynamic allocation of IP addresses from an
OpenVMS host.
Security
New Feature:
• SSH Upgrade with Kerberos Support
The TCP/IP Services for OpenVMS product includes the
secure shell (SSH) client and server, which provide se-
cure login, remote command execution, and file transfer.
TCP/IP Services for OpenVMS 5.6 includes SSH sup-
port for Kerberos, the popular network authentication
protocol from the Massachusetts Institute of Technol-
ogy. SSH password authentication method has been
enhanced to support Kerberos.
Performance and Scalability
The TCP/IP kernel has been modified to provide in-
creased performance on symmetric multiprocessing
(SMP) systems.
This complete redesign of the TCP/IP kernel provides
enhanced performance on SMP systems by removing
CPU contention among users. The new kernel uses a
dynamic spinlock to lock the main internal database. All
processing that requires locking is directed to a desig-
nated TCP/IP CPU, thereby eliminating CPU contention
with other CPU users. Essentially, network I/O be-
comes a series of asynchronous, transaction-based op-
erations.
Management Control Program
The TCP/IP Services for OpenVMS product provides the
Management Control Program, which is a comprehen-
sive, easy-to-use network management tool based on
familiar OpenVMS DCL command syntax. These com-
mands let system managers configure and monitor the
product components locally.
The flexible configuration process includes an interac-
tive configuration procedure.
Startup and shutdown files are provided for individual
services, allowing system managers to stop and start
individual services without affecting the operation of the
remaining TCP/IP Services software.
Support for both DCL or UNIX management commands
provides a choice of methods for configuring and man-
aging the network connections and the TCP/IP Services
software.
UNIX Network Management Utilities
• TCPDUMP Version 3.8.3 for IPv4 and IPv6
The TCP/IP Services for OpenVMS product provides
UNIX networking management utilities for system man-
agers who are experienced in managing and trou-
bleshooting the UNIX network subsystem. Supported
utilities include:
• arp
• finger
• ifconfig
• netstat
• ping
• ripquery
• route
• sysconfig
• sysconfigdb
• tcptrace
• traceroute
• tcpdump
Subsystems can be configured in the sysconfigtab
database.
Note that some UNIX flags and parameters may not be
supported.
Error Message Documentation
The TCP/IP Services for OpenVMS product provides
online help for error messages for TCP/IP facilities and
components. The information is included as part of the
OpenVMS Help Message utility (MSGHLP).
