yppoll asks a ypserv.8 process what the order number is, and which host is the Network Information Service (NIS) master server for the named map. If the server is a v.1 NIS protocol server, yppoll uses the older protocol to communicate with it. In this case, it also uses the older diagnostic messages in case of failure.
The Network Information Service (NIS) was formerly known as Sun Yellow Pages (YP). The functionality of the two remains the same; only the name has changed. The name Yellow Pages is a registered trademark in the United Kingdom of British Telecommunications plc, and may not be used without permission.
