HP-UX Integrated Login

Integrating DCE with HP-UX Integrated Login

•Unlike user root, the cell administrator must provide cell_admin’s password when using the HP-UX Integrated passwd to change other users’ passwords in the DCE Security Registry.

•User passwords are limited to 128 characters for ftp; otherwise, passwords can be up to 512 characters.

•HP-UX Integrated Login utilities take longer to execute and require more system resources than the HP-UX equivalents.

•For operations that do not require the user to enter a password, no DCE credentials are obtained. Examples include:

-su when executed by root

-rlogin when an .rhosts file authorizes access

-Anonymous ftp

Preparing to Integrate DCE with HP-UX Integrated Login

Before integrating DCE with HP-UX Integrated Login on a system, you must prepare as follows. You can configure DCE as either the login technology or as an additional technology.

If you plan to configure DCE as the login technology:

•Configure the system as a DCE cell member.

•Set up a valid root account in the DCE Security Registry.

•Set up valid accounts in the DCE Security Registry for all users that require login access to the cell, or local login access to cell member systems. Use either dcecp or passwd_import to set up accounts.

•Decide whether to configure ux as the fallback technology, and, if so, whether to export DCE Registry data to /etc/passwd via a passwd_export entry in your crontab file. It is recommended that you use this mechanism to keep the local password file synchronized with the DCE Registry, in the event that fallback login is needed. (See “Activating HP-UX Integrated Login” in this chapter for further information.)

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.
