  NAME

    yppoll - Checks the version of a Network Information Service (NIS) map at
    an NIS server host

  SYNOPSIS

    /etc/yp/yppoll [-h host] [-d domain] mapname

  FLAGS

    -h host     Asks the ypserv process at host about the map parameters.  If
                host is not specified, the NIS server for the local host is
                used.  That is, the default host is the one returned by
                ypwhich.

    -d domain   Uses domain instead of the default host domain.

  DESCRIPTION

    The yppoll command asks a ypserv process for the order number and the host
    that is the master Network Information Service (NIS) server for the named
    map.  If the server is a version 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.

  EXAMPLES

    To determine the version of and server for the NIS map passwd.nam for the
    client sys2, enter:

    /etc/yp/yppoll -h sys2 passwd.nam


  DIAGNOSTICS

    yppoll:  can't find host
           The specified hostname is not present in the /etc/hosts file.

    yppoll:  domainname hasn't been set on this machine
           The ypinit command probably has not been executed on this system.
           The ypinit command sets the domain name and edits /etc/nfs to
           configure it to set the domain name on subsequent reboots.

  EXIT VALUES

    The yppoll command exits with a value of 0 if successful.  If
    unsuccessful, it exits with a value of 1.
