To enter commands in File mode, you specify a file from which vcaadm reads one or more commands. The file must be ASCII text, consisting of one command per line. Begin each comment with a pound sign (#) character. If the File mode option is set, vcaadm ignores any command-line arguments after the last option. The following example runs the commands in the deluser.scr file and answers all prompts in the affirmative:

$ vcaadm -f deluser.scr -y

Interactive Mode

In Interactive mode, you must authenticate as security officer every time you connect to a board. This is the default operating mode for vcaadm. To logout of vcaadm in Interactive mode, use the logout command. Refer to “Logging In and Out With vcaadm” on page 58.

Interactive mode presents the user with an interface similar to ftp(1), where commands can be entered one at a time. The -yoption is not supported in interactive mode.

Logging In and Out With vcaadm

When you use vcaadm from the command-line and specify host, port, and device using the -h, -p, and -dattributes respectively, you are immediately prompted to log in as security officer if a successful network connection was made.

The vcaadm program establishes an encrypted network connection (channel) between the vcaadm application and the Sun Crypto Accelerator 4000 firmware running on a specific board.

During setup of the encrypted channel, boards identify themselves by their hardware Ethernet address and an RSA public key. A trust database ($HOME/.vcaadm/trustdb) is created the first time vcaadm connects to a board. This file contains all of the boards that are currently trusted by the security officer.

4000 specifications

Sun Microsystems, a pivotal player in the computing industry during the late 20th and early 21st centuries, was renowned for its innovative hardware and software solutions. Among its notable offerings were the Sun-6000, Sun-5000, and Sun-4000 series, powerful workstations and servers designed for a range of enterprise-level applications.

The Sun-6000 series, introduced in the early 1990s, marked a significant advancement in computing performance. These systems were built on the SPARC architecture, which facilitated high levels of processing power and multitasking capabilities. One of the main features of the 6000 series was its scalability, allowing organizations to increase their processing power by adding more modules. It also offered robust graphics performance, making it ideal for scientific visualization and complex data analysis.

Next in line was the Sun-5000 series. Launched shortly after the 6000 series, the 5000 line was celebrated for its reliability and ease of management. This series emphasized a balanced architecture, which combined processing capabilities with ample memory and storage options. Key characteristics included support for multiple processors, leading to improved performance for demanding applications. Additionally, the 5000 systems featured advanced input/output capabilities, ensuring fast data transfers—crucial for database applications and web servers.

Finally, the Sun-4000 series targeted businesses seeking affordable yet potent computing solutions. These servers boasted a modular design, allowing for easy upgrades and maintenance. The 4000 series was particularly notable for its support for various operating systems, including SunOS and Solaris. These systems were engineered to handle a range of workloads, from enterprise resource planning to web hosting, while still fitting into a value-driven budget.

Across all three series, Sun Microsystems prioritized compatibility and integration, ensuring that each system offered seamless connectivity with Sun's software solutions and third-party applications. Their commitment to open standards and interoperability set them apart in the competitive landscape of enterprise computing. Additionally, the use of high-quality components lent the systems durability, making them a wise investment for organizations looking to future-proof their IT infrastructure.

In summary, the Sun-6000, 5000, and 4000 series exemplified Sun Microsystems' ethos of innovation and reliability. These powerful systems catered to diverse business needs, setting benchmarks in performance and functionality that continue to influence modern computing.
