Certificates in the chain are assumed to be valid for client authentication as well, when client authentication (SSLVerifyClient) is used.

8.SSLCACertificateFile file Context: Global, virtual host

This directive specifies the location of a file containing the concatenation of the certificates for certification authorities (CAs) used for client authentication.

9.SSLCARevocationFile file

Context: Global, virtual host

This directive specifies the location of a file containing the concatenation of the certificate revocation lists of CAs used for client authentication.

10.SSLVerifyClient level

Context: Global, virtual host, directory, .htaccess

This directive configures the authentication of clients to the server. (Note that this is not normally needed for e-commerce applications, but has use in other applications.)

Values for level are listed and described in TABLE B-5.

TABLE B-5SSL Verify Client Levels

Level

Description

 

 

none

No client certificate is required

optional

Client may present a valid certificate

require

Client must present a valid certificate

optional_no_ca

Client may present a certificate, but it need not be valid

 

 

Typically either none or require is used. The default is none.

11.SSLVerifyDepth depth

Context: Global, virtual host, directory, .htaccess

This directive specifies the maximum certificate chain depth that the server will allow for client certificates. A value of 0 means that only self-signed certificates are eligible, whereas a value of 1 means that client certificates must be signed by a CA known directly to the server (through the SSLCACertificateFile). Larger values permit delegation of the CA.

12.SSLLog filename

Context: Global, virtual host

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.
