yp-tools binary package in Ubuntu Mantic amd64

 This package provides a number of tools for working with NIS
 installations including ypset, ypwhich, ypcat, ypmatch, yppoll,
 ypchfn, ypchsh and yppasswd.
 .
 NIS, originally known as Yellow Pages (YP), is mostly used to let
 several machines in a network share the same account information, such
 as the password file. It is an old, but simple system to share information,
 which should be used only in relatively trusted networks, due to its
 intrinsic limitations for security.
