NAME

ypwhich - lists which host is the Yellow Pages server
          or map master

SYNOPSIS

ypwhich
ypwhich [ -d domain ] [ -V1 | -V2 ] [ hostname ]
ypwhich [ -d domain ] [ -t ] [ -m [ mname ] ]
ypwhich −x

DESCRIPTION

The ypwhich command lists the host name of the Yellow Pages (YP) server that supplies YP services to a YP client. It can also print the YP 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 YP map can be referenced. 

If invoked without arguments, ypwhich prints the host name of the YP server serving the local machine.  If hostname is specified, that machine is queried to determine which YP server it is using. 

Options

−d Specify a domain other than the one returned by domainname(1).

−V1 List the server that is serving Version 1 YP protocol-speaking client processes. 

−V2 List the server that is serving Version 2 YP 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 YP servers and YP 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 YP server for a map.  No hostname can be specified with −m.  The mname can be a mapname or a map nickname. If mname is omitted, a complete list of available maps and the corresponding host names of the master YP servers is produced. 

−xDisplay the table that lists the nickname for each YP map.
