Another way to tell: is your NIS server a Linux machine? If so, it can only
be NIS (yp) as there is no NIS+ server implementation for Linux (nor will
there likely ever be one).

NIS+ support for Linux is limited to allowing Linux clients to join an
existing NIS+ network with Solaris NIS+ servers.

"ypmatch <username> auto_home" will tell you where each home directory is
being
mounted from (for NIS/YP).
