Creating a Cyberdog Service

This document is an addendum to Part 2 of the Cyberdog Programmer's Kit. It outlines the steps you take to implement a Cyberdog service, which provides a network protocol. A network protocol defines the conventions for communication between interconnected computers. Cyberdog supports HTTP, Gopher, FTP, Telnet, and SMTP protocols. You only need to create a service to replace an existing service or to support a protocol that is not already provided by Cyberdog. This document shows you how to implement

• a Cyberdog service class and a service ('srvc') resource
• a service's Cyberdog menu items
• a Cyberdog item class representing the kind of item that your service manipulates
• a Cyberdog stream class to retrieve data from the item's location
• parts to display the Connect To and Preferences panels

This addendum shows how to use these classes and parts to create a Finger service, which is a protocol built on TCP to query a host computer for the login status of a user. The examples shown here are based on the FingerService sample. Complete source code for the sample is on the Cyberdog Programmer's Kit CD.
