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 ] MapName

Description

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 map name, be sure to enter the map's full name. The yppoll command does not recognize map nicknames.

Flags

-h Host	Enables you to specify a server other than the default server. To find out which server the command defaults to, use the ypwhich command.
-d Domain	Enables you to specify a domain other than the default domain. To find out which domain the command defaults to, use the domainname command.

Examples

To look at a map located on a particular host, enter:
```
/usr/sbin/yppoll -h thor netgroups.byuser
```
In this example, the yppoll command displays the order number for the netgroups.byuser map located on the host named thor.
To look at a map on a domain, enter:
```
/usr/sbin/yppoll -d atlantis hosts.byname
```
In this example, the ypoll command displays the order number for the hosts.byname map located in the domain atlantis.
