About HP DCE/9000 Version 1.7

HP DCE/9000 Core Services Software

See “Establishing Peer-to-peer Trust” in Chapter 7 for more information on these important new options.

HP has added a new -roption, which refreshes a user’s credentials, to dce_login. Users are encouraged to use dce_login -rrather than kinit to refresh their credentials, since dce_login -ruses the more secure DCE Third-party preauthentication protocol, whereas kinit uses the less secure Kerberos 5 Timestamps protocol.

HP has changed the default behavior of its configuration tools to automatically enable audit filtering. In addition, the default behavior of secd has been changed to enable audit filtering at start-up, and a new secd option, -noauditfilters, had been added to disable audit filtering. See “Configuring the DCE Audit Service” in Chapter 5, and the online secd man page for more information.

HP DCE Measurement Service (DMS) to monitor resource utilization and performance of HP DCE 1.6 servers.

Support for large uids.

Support for context-switching 64-bit machine registers in DCE threads ( libcma and libdce).

Support for MC/ServiceGuard.

Support for Secure Remote Utilities (Secure Internet Services) in the InternetSrvcs product.

Features Added at HP DCE 1.7

The following features are new at HP DCE 1.7:

NSS-DCE: a DCE module for the Name Service Switch (see “Integrating DCE with HP-UX Integrated Login” in Chapter 6 for more information).

DCE support for Kerberos V5 applications through creation of configuration and keytab files.

All integrated login utilities, including ftpd, now use the Pluggable Authentication Module (PAM). There are no longer any separate

.auth binaries.

In addition, HP DCE 1.7 contains numerous bug fixes.

UX DCE Software specifications

HP UX DCE Software, or Hewlett-Packard UNIX Distributed Computing Environment, represents a significant tool in the realm of distributed system architecture. Designed primarily for enterprise environments, HP UX DCE enhances the reliability, scalability, and manageability of applications over diverse networked systems.

One of the main features of HP UX DCE is its ability to integrate various computing platforms, enabling seamless communication and resource sharing across distributed nodes. This facilitates the creation of complex applications that can operate on a multitude of systems, thus enhancing operational flexibility. DCE employs standardized interfaces, which means applications written for one platform can run on any other platform that supports DCE, promoting cross-platform compatibility.

In terms of technologies, HP UX DCE utilizes Remote Procedure Calls (RPC) as a core feature. This mechanism allows different applications to communicate and invoke procedures on remote systems as if they were local calls. Additionally, DCE includes a robust security model that incorporates Kerberos for authentication, ensuring that communication between nodes remains secure and protected against unauthorized access.

Another significant characteristic of HP UX DCE is its distributed file system, which allows for transparent file access across different machines. The DCE File System (DFS) provides a unified namespace and manages data replication and consistency across distributed storage resources. This reduces the complexity of data management and enhances data availability.

HP UX DCE also supports a variety of programming languages, making it accessible for developers accustomed to different coding environments. This versatility encourages widespread adoption and innovation, as developers can leverage existing skills to create distributed applications.

Furthermore, HP UX DCE is built for high availability, ensuring that critical applications remain responsive even in the face of hardware or network failures. Its inherent component redundancy and fault-tolerant architecture are designed to minimize downtime, which is essential for mission-critical applications in enterprise scenarios.

In conclusion, HP UX DCE Software provides a comprehensive framework for developing, deploying, and managing distributed applications. Its core features such as RPC support, a secure authentication mechanism, a robust file system, and cross-platform compatibility make it a vital resource for organizations aiming to leverage distributed computing effectively. As enterprises evolve, HP UX DCE stands out as an influential solution in the dynamic landscape of distributed environments.
