NAME
ypwhich - list which host is Network Information System server or map master
SYNOPSIS
ypwhich
ypwhich
[-d domain ][-V1
-V2][hostname ]
ypwhich [-d domain ][-t][
-m [ mname ]]
ypwhich -x
Remarks
The Network Information Service (NIS) was formerly known as Yellow Pages (yp). Although the name has
changed, the functionality of the service remains the same.
DESCRIPTION
ypwhich lists the host name of the Network Information System (NIS) server that supplies NIS services
to a NIS client. It can also print the NIS server that is the master for mname. The mname can be either a
mapname or a map nickname. A map nickname is a synonym by which a NIS map can be referenced.
If invoked without arguments,
ypwhich prints the host name of the NIS server serving the local machine.
If hostname is specified, that machine is queried to determine which NIS server it is using.
Options
ypwhich recognizes the following command-line options and arguments:
-d Specify a domain other than the one returned by domainname(1).
-V1 List the server that is serving Version 1 NIS protocol-speaking client processes.
-V2 List the server that is serving Version 2 NIS protocol-speaking client processes.
If neither version is specified, ypwhich locates the server supplying the Version 2
(current) services. However, if no Version 2 server is found,
ypwhich attempts to locate
the server supplying the Version 1 services. Since NIS servers and NIS clients are both
backward compatible, the user seldom needs to know which version is being used.
-t Inhibit the translation of a map’s nickname to its corresponding mapname. For example,
ypwhich -t -m passwd fails because there is no map named passwd,whereas
ypwhich -m passwd translates to ypwhich -m passwd.byname
. This option
is useful if a mapname is identical to a nickname (which is not true of any HP map).
-m [mname ]
List the master NIS server for a map. No hostname can be specified with
-m. The
mname can be a mapname or a map nickname.Ifmname is omitted, a complete list of
available maps and the corresponding host names of the master NIS servers is produced.
-x Display the table that lists the nickname for each NIS map.
