This chapter describes new features of TCP/IP Services Version 5.5 as well as behavioral enhancements.
TCP/IP Services Version 5.5 is supported on OpenVMS Alpha and OpenVMS Industry Standard 64 for Integrity Servers (I64) systems only. On VAX systems, use TCP/IP Services Version 5.3. To use TCP/IP Services Version 5.5, you must upgrade to OpenVMS Version 8.2 or higher. |
For information about installing and configuring TCP/IP Services, see the HP TCP/IP Services for OpenVMS Installation and Configuration guide.
Table 1-1 lists the new features of TCP/IP Services Version 5.5 and the sections that describe them.
| Feature | Section | Description |
|---|---|---|
| Support for HP Industry Standard 64 Server Platforms | 1.1 | TCP/IP Services runs on I64 platforms as well as Alpha platforms. |
| failSAFE IP Support for IPv6 | 1.2 | failSAFE IP supports IPv6. This version of TCP/IP Services includes new ifconfig commands for managing failSAFE IP. |
| Secure IMAP | 1.3 | Secure IMAP uses the Secure Sockets Layer (SSL). |
| IPv6 Updates and Enhancements | 1.4 | Neighbor discovery and IPv6 APIs have been enhanced. |
| libpcap API Support | 1.5 | The libpcap application programming interface (API) is supported in this release of TCP/IP Services. |
| Support for Network Time Protocol (NTP) V4.2 | 1.6 | NTP has been upgraded to Version 4.2 and supports IPv6. |
| SSH Features | 1.7 | SSH has been upgraded to Version 3.2 and supports IPv6. |
| TCPDUMP Version 3.8.3 | 1.8 | TCPDUMP has been upgraded to Version 3.8.3. |
| Updated Header Files in TCPIP$EXAMPLES | 1.9 | Header files residing in TCPIP$EXAMPLES have been updated. |
TCP/IP Services now runs on HP Itanium®-based (I64) platforms, providing essentially the same functionality as on Alpha platforms. Further information about I64 support is provided in the following sections:
The failSAFE IP service has been upgraded in this release. The IPv6 environment is now supported.
The ifconfig utility has been updated as well. For more information about this utility, enter the following command:
$ TCIPIP HELP IFCONFIG |
For more information about using the
ifconfig
utility to monitor interface failover, refer to the HP TCP/IP Services for OpenVMS Management guide.
1.3 Secure IMAP
This release of TCP/IP Services includes secure IMAP, which supports the Secure Sockets Layer (SSL). Secure IMAP provides secure retrieval and management of messages. Secure IMAP accepts connections on port 993 and encrypts passwords, data, and IMAP commands. It is compatible with clients that use SSL, such as Outlook Express, Netscape, and Mozilla. To use this feature, you must download the HP SSL kit for OpenVMS Alpha from the HP OpenVMS Security web site:
http://h71000.www7.hp.com/openvms/security.html |
If the HP SSL software is not installed, the IMAP server will communicate in non-SSL mode.
The SSL logical names are defined by the SSL startup procedure. Therefore, if you have IMAP configured to use SSL logical names for locating the certificate and key files, you must ensure that the SSL startup procedure is run before the TCP/IP Services startup procedure.
The secure IMAP configuration is controlled by the configuration file SYS$SYSDEVICE:[TCPIP$IMAP]TCPIP$IMAP.CONF.
Use the following new configuration options and logical names to manage secure IMAP:
SSL-Server-Port:1004 |
The IMAP server serves ONLY SSL client requests. Please reconfigure your client for SSL. |
Disable-Clear-Text:YES |
Disable-SSL:YES |
$ DEFINE/SYSTEM/EXECUTIVE_MODE TCPIP$IMAP_CERT_FILE SSL$CERTS:TCPIP$IMAP.CRT |
$ DEFINE/SYSTEM/EXECUTIVE_MODE TCPIP$IMAP_KEY_FILE SSL$KEY:TCPIP$IMAP.KEY |
To ensure that logical names and configuration options take effect, you
should stop the IMAP server before you change them.
1.4 IPv6 Updates and Enhancements
The following sections describe updates and enhancements to IPv6 (Internet Protocol Version 6) functionality.
For additional information about IPv6 changes, see Section 4.7.
1.4.1 IPv6 Configuration Enhancements
The support for IPv6 has been enhanced to include dynamic updates for
the
ip6.arpa
zone and updates to the IPv6 APIs.
1.4.2 Neighbor Discovery Supports Dynamic Update Requests for ip6.arpa DNS Reverse Zone
Neighbor Discovery (TCPIP$ND6HOST process) now supports RFC 3152 and can be configured to send dynamic update requests for the ip6.arpa DNS reverse zone only.
Previously, the Neighbor Discovery daemon would send dynamic update requests for the ip6.int DNS reverse zone only. (The ip6.int reverse zone is being deprecated.)
If you need to support delegations based on the ip6.int zone, make sure that the ip6.int zone gets populated correctly. For more information, refer to Section 3.1.3, Using DNAME To Rename ip6.int , in the HP TCP/IP Services for OpenVMS Guide to IPv6.
To update the zone, TCPIP$ND6HOST sends dynamic updates to the primary master name server. The name of the primary master name server is stored in the MNAME field of the SOA record for a zone. To determine the master name server, TCPIP$ND6HOST sends a query for the zone's SOA record to the name server specified in the DNS resolver configuration. To display the DNS resolver configuration information, use the TCP/IP management command SHOW NAME_SERVICE.
To make use of this feature, you must enable dynamic updates. By default, dynamic updates are rejected by DNS servers. For information about allowing dynamic updates, see the BIND Chapter in the HP TCP/IP Services for OpenVMS Management guide.
