Administering an ISP Installation

Inspired Technologies ISP wants to deliver services for several businesses that cannot afford or do not want to spend money on an in-house Internet gateway. These businesses do, however, want Internet services such as:

• Simple Mail Transfer Protocol (SMTP) and POP3 access to e-mail.
• A Network News Transfer Protocol (NNTP) server for dedicated use (in other words, customer support).
• A Web-hosting server.
