Configuring Domain Name Files

Create or Modify the Hosts File

Create or Modify the Hosts File

The host name data base file, (HOSTS.NET.SYS), associates internet addresses with official host names and aliases. This allows a user to refer to a host by a symbolic name instead of an internet address.

When you have configured the name server, this file serves only as a backup when the server is not running. In this circumstance, it is a common practice that HOSTS.NET.SYS contains a few addresses of machines on the local network.

To create the hosts file, perform the following steps:

Step 1. Copy the sample file, HOSTSAMP.NET.SYS, to HOSTS.NET.SYS. Step 2. Modify HOSTS.NET.SYS using any ASCII editor so that it contains

 

information about the nodes on your network.

 

To modify an already existing HOSTS.NET.SYS file, simply use your

 

editor to update and save the existing file.

 

Enter a single line for each host, including the following information:

 

[internet address] [local host name] [aliases]

 

A line cannot start with a space. Items are separated by any number of

 

blanks and/or tab characters. A pound sign (#) indicates the beginning

 

of a comment.

 

Network addresses are specified in dot format, with leading zeros

 

omitted and a period between each grouping. (See example addresses in

 

Figure 12-2.)

 

Host names can contain any printable character other than a white

 

space, newline, or comment character.

 

It is very important that you omit the leading zeros in the network

NOTE

 

addresses. If you enter the leading zeros here, the domain name

 

resolver will interpret the numbers as octal numbers.

E3000 MPE/IX, E3000/IX specifications

The HP E3000 series, particularly the E3000/IX and E3000 MPE/IX, represents a significant milestone in the evolution of business computing, developed by Hewlett-Packard (HP) during the late 1970s and early 1980s. These systems were designed to provide robust, reliable, and efficient operation for mid-sized businesses, leveraging the power of the MPE (Multi-Programming Executive) operating system.

One of the main features of the HP E3000 series is its multitasking capability. MPE/IX allows for multiple applications to run concurrently, maximizing the utilization of system resources. This is particularly beneficial for organizations that require simultaneous access to various business applications, ensuring enhanced productivity and efficiency.

The HP E3000/IX architecture is built on a powerful 16-bit or 32-bit microprocessor, enabling it to handle substantial workloads. The system architecture is known for its modular design, which allows for easy upgrades and customization. This flexibility is essential for businesses that need to adapt to changing demands without overhauling their entire computing infrastructure.

Another notable technology incorporated into the HP E3000 series is its support for a range of storage solutions. The E3000 systems were compatible with various disk drives, providing organizations with options for data storage that matched their performance and capacity requirements. Additionally, they featured advanced data management capabilities, such as built-in backup and recovery systems, ensuring that critical business information remained secure and accessible.

Beyond hardware capabilities, HP E3000/IX and MPE/IX systems provide extensive programming support. They included tools for developing custom applications, with support for languages such as COBOL, BASIC, and FORTRAN. This versatility made it easier for businesses to tailor their software solutions to their specific needs, enhancing operational effectiveness.

Networking capabilities were also a significant innovation of the E3000 series. The systems offered robust support for various networking protocols, allowing for seamless integration with other computing environments. This facilitated communication and collaboration within an organization, as well as with external partners and clients.

In summary, the HP E3000/IX and E3000 MPE/IX systems were pivotal in delivering reliable computing power to mid-sized enterprises. With their multitasking operating system, modular architecture, advanced data management, and programming support, these systems provided an adaptable and comprehensive solution for evolving business needs. The legacy of the E3000 series is evident in how it paved the way for modern enterprise computing, focusing on flexibility, scalability, and efficiency.
