yppoll Command
Purpose
Displays the order number (ID number) of the Network Information Services (NIS) map currently in use on the server.
Syntax
/usr/sbin/yppoll [ -h Host ] [ -d Domain ] MapNameDescription
The yppoll command uses the ypserv daemon to display the order number of the map you specify in the MapName parameter. An order number is a map's ID number and is assigned by the system. This number changes whenever a map is updated. Use the yppoll command whenever you want to make sure your servers are using the most current version of a particular map.
The yppoll command
can run on systems that have either version 1 or version 2 of the Network Information Services (NIS) protocol installed.
Be aware, however, that each version of the protocol has its own set
of diagnostic messages.
Note: When
specifying a MapName, be sure to enter the map's full name.
The yppoll command does not recognize map nicknames.
