ypserv - 4.2-2+b2 main

This package provides the ypserv and other programs, required
to implement a NIS service for shared accounts and network names.
.
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.
