Clients and daemons for the Network Information Services (NIS)
 The nis package allows you to use the NIS services from a NIS server or
 to set up your own NIS server. NIS is mostly used to let several machines
 in a network share the same account information (eg the password file).
 NIS was formerly called Yellow Pages (YP).
