HP-UX Integrated Login

Operation of Integrated Login Utilities

Operation of Integrated Login Utilities

The Integrated Login utilities are login, dtlogin, dtsession, su, and ftpd. The passwd utility is also integrated to facilitate the manipulation of registries (such as the registries for technologies used by HP-UX Integrated Login.) The Secure Internet Services (SIS) version of ftpd is not integrated. The SIS versions of rlogin and telnet provide the integrated login service when login on the remote system requires a password.

The Integrated Login utilities attempt to first authenticate a user via the login technology. If the login technology is not available or fails, and a fallback technology is configured, the user is authenticated via the fallback technology. If none of the authentications succeed, then the user is denied access to the local system. Note that fallback will not occur if the login technology specifically denies access to a user (such as the user name is recognized, but the password is incorrect; or a time-based authorization does not allow the user to log in at that time).

After a user is successfully logged in, the Integrated Login utilities attempt to authenticate the user to all additional technologies configured. Any failure in this step is not fatal. The user is still allowed to log in and is appropriately warned of the failures.

Upon unlocking the HP-CDE session, the integrated dtsession attempts to refresh all credentials a user has obtained through integrated dtlogin.

If passwd successfully changes a user’s password in the login registry, it also attempts to make the change in the registries of all other technologies configured.

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.
