Abstract
The Guardian Gazette consists of a chapter per program, process, or subsystem, each containing a discussion of the object, the security concerns and best practice recommendations. The chapter details the Distributed Systems Management Configuration Manager (DSM/CSM) subsystem, which is used to install the new releases by HP into a running system. These releases comprise of new operating systems or revised software products updated by HP periodically. The discussion also includes various user programs, system programs, and system utilities. The Network File System (NFS) is a widely used and primitive protocol that allows computers to share files over a network. The implementation on the HP NonStop Server is based on that developed by Sun Microsystems. It allows PCs or other network hosts to create or use files on the NonStop Server via TCP/IP over a LAN. The components, configuration, and ways to secure the components of the NFS subsystem are also discussed. The chapter also highlights the RPC file that is an EDIT file containing program definitions. The definitions include the program name, program number and possible aliases for the program name, and Remote Procedure Call (RPC) Subsystem that provides a standard way to invoke services. Another important subsystem is the Tandem Service Management (TSM) subsystem that is used to manage HP S-series NonStop systems. It is a client/server application with a PC GUI client communicating with the Non- Stop Server via TCP/IE
