yppoll(NADM)                    19 June 1992                    yppoll(NADM)


 Name

    yppoll - what version of an NIS map is at an NIS server host

 Syntax

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

 Description

    yppoll asks a ypserv process for the order number and the hostname of the
    master NIS 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.

 Options


    -h host
       ask 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(NADM).

    -d domain
       use domain instead of the default domain
