ypwhich - determine which host is the current NIS server
or map master.
ypwhich [-d domain] [-V1] [-V2] [hostname]
ypwhich [-d domain] [-m[mname]] [-t[mapname]]
Identifies which server is serving v.1 NIS protocol-speaking
client processes. 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 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 omitted, ypwhich provides a list of
available maps. Inhibits nickname 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.
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 without 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.
