# yppoll(8)

ask version of NIS map from NIS server

## NAME

**yppoll** – ask version of NIS map from NIS server

## SYNOPSIS

**yppoll** \[**-d** *domain*\] \[**-h** *host*\] *mapname*

## DESCRIPTION

**yppoll** asks a NIS server process for the order number and which host is the master server for *mapname*.

The options are as follows:

- **-d** *domain*

  Use the NIS domain *domain* instead of the default domain as returned by [domainname(1)](/domainname/1.md).

- **-h** *host*

  Ask the NIS server process running on *host* for information about *mapname*. If *host* is not specified, the server polled is the default server returned by [ypwhich(1)](/ypwhich/1.md).
