ypwhich(1)ypwhich(1)NAMEypwhich - determine which host is the current NIS server or map master.
SYNOPSISypwhich [-d domain] [-V1] [-V2] [hostname]
ypwhich [-d domain] [-m[mname]] [-t[mapname]]
ypwhich-x
OPTIONS
Identifies which server is serving v.1 NIS protocol-speaking client
processes. Identifies which server is serving v.2 NIS protocol-speak‐
ing 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 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. Uses domain
instead of the current domain. 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 omit‐
ted, ypwhich provides a list of available maps. Inhibits nick‐
name translation and is useful if there is a mapname identical
to a nickname. Displays the map nickname table. This option
lists the nicknames (mnames) that the command knows of, and
indicates the mapname associated with each nickname.
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.
