yptest - test NIS configuration
yptest [-q] [-d domain] [-h host] [-m map] [-u user]
yptest calls various NIS functions to check if the NIS configuration is
correct and works as expected.
-q Be quiet, don’t print messages
Specify a domain other than the default domain as returned by
domainname(1). This option is not supported by all tests.
Query ypserv on hostname instead of the currently used one.
This option is not supported by all tests.
-m map Use the map map for the tests instead of passwd.byname. This
option should be used if the default map does not exist.
Use the account user instead of nobody. This option should be
used if the nobody account does not exist in the map used for
testing (passwd.byname or the one given with the -m option).
domainname(8), ypbind(8), ypcat(8), ypmatch(1), ypserv(8), yppoll(8),
