YPWHICH(1) General Commands Manual YPWHICH(1)
ypwhich - return hostname of NIS server or map master
ypwhich [ -d domain ] [ -m [ mname ] [ -t ] | [ -V1 | -V2 ] hostname ]
This command is available with the Networking software installation
option. Refer to for information on how to install optional software.
ypwhich tells which NIS server supplies NIS services to an NIS client,
or which is the master for a map. If invoked without arguments, it
gives the NIS server for the local machine. If hostname is specified,
that machine is queried to find out which NIS server it is using.
Refer to ypfiles(5) and ypserv(8) for an overview of the NIS services.
-d Use domain instead of the default domain.
-V1 Which server is serving v.1 NIS protocol-speaking client pro-
-V2 Which server is serving v.2 NIS protocol 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 then attempts to locate the
server supplying 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.
-t Inhibit nickname translation; useful if there is a mapname iden-
tical to a nickname. This is not true of any Sun-supplied map.
-m Find the master NIS server for a map. No hostname can be speci-
fied with the -m option. mname can be a mapname, or a nickname
for a map. When mname is omitted, produce a list of available
-x Display the map nickname table. This lists the nicknames
(mnames) the command knows of, and indicates the mapname associ-
ated with each nickname.
