1. Introduction

1.1. Purpose

This tutorial presents a number of related topics that allow an administrator to seamlessly integrate mirroring and update services for Fedora Core. Use these services to provision a classroom, laboratory, or office. These service provisions also increase ease of use and enhance user experience. They also add to the perceived value of non-proprietary operating systems and software.

1.2. Audience

  • Fedora Core system installation and administration

  • Basic Internet protocols (HTTP/Web)

  • Using a command line interface

1.3. About Mirrors

A mirror is a server that provides a copy of one or more collections of files. Mirroring a site reduces traffic to the original source site, thus spreading the stress and bandwidth costs of many users across many sites. Side benefits of running a local mirror include very fast access through the local network, providing custom services to local users, and increasing your skills in managing Internet services.

The site from which you retrieve files to build your mirror is called an upstream mirror. If possible, choose an upstream mirror that is located close to you geographically. This reduces unnecessary traffic across transcontinental sections of the Internet, where bandwidth is limited and expensive. Use only upstream mirrors that are intended for public access, unless you have permission from the upstream mirror site administrator.
