ypwhich(1) General Commands Manual ypwhich(1) NAME ypwhich - determine which host is the current NIS server or map master. SYNOPSIS ypwhich [-d domain] [-V1] [-V2] [hostname] ypwhich [-d domain] [-mname]][-tapname]] ypwhich -x DESCRIPTION The ypwhich command identifies the Network Information Service (NIS) server that currently supplies NIS services to an NIS client. It also identifies which NIS server is the master for a map. If invoked with- out arguments, ypwhich returns the host name of the NIS server for the local machine. If hostname is specified, ypwhich checks that machine to find out which NIS master it is using. Refer to ypfiles(4) and ypserv(8) for an overview of NIS. FLAGS -V1 Identifies which server is serving v.1 NIS protocol-speaking client processes. -V2 Identifies which server is serving v.2 NIS protocol-speaking client processes. If neither version is specified, ypwhich attempts to locate the server that supplies the current v.2 services. If there is no v.2 server currently bound, ypwhich attempts to locate the server sup- plying the v.1 services. Since NIS servers and NIS clients are both backward compatible, the user need seldom be concerned about which version is currently in use. -d Uses domain instead of the current domain. -m name] Finds the master NIS server for a map. No hostname can be specified with -m. The mname argument can be a mapname, or a nickname for a map. When mname is omitted, ypwhich provides a list of available maps. -t mapname Inhibits nickname translation and is useful if there is a mapname identical to a nickname. -x Displays the map nickname table. This option lists the nicknames (mnames) that the command knows of, and indicates the mapname asso- ciated with each nickname.
