Usually Sun style NIS setups are VERY bad. They assume an age of LONG ago, where NIS was supposed to be the "all in all"... thus Sun likes to push ALL users and handles all map types... Good Linux distros, esp. SUSE (where NIS works best) have decent yp makefiles, etc. We converted our Solaris 7 based NIS about 9 years ago to SUSE... it's currently SLES 10 based... we couldn't be happier.
Recommendation, you DON'T want "everything"... again, if it's a typical Sun NIS, it's sorta stupid. Push the users out that make sense, don't push a host map (use DNS).. etc...
We just push passwd, group, netgroup and maps for our NFS automount maps.
If you're using SSH, one things we're looking at doing is invalidating our DES crypt hashes in the passwd map and moving to key login... for some added security.

NAME
ypwhich - return name of NIS server or map master
SYNOPSIS
ypwhich [-d domain] [ [-t] -m [mname] | [-Vn] hostname]
ypwhich -x
DESCRIPTION
ypwhich returns the name of the NIS server that supplies the NIS name services to a NIS client, or which is the master for a map. If
invoked without arguments, it gives the NIS server for the local machine. If hostname is specified, that machine is queried to find out
which NIS master it is using.
Refer to ypfiles(4) for an overview of the NIS name services.
OPTIONS
-d domain Use domain instead of the default domain.
-t This option inhibits map nickname translation.
-m mname Find the master NIS server for a map. No hostname can be specified with -m. mname can be a mapname, or a nickname for a
map. When mname is omitted, produce a list of available maps.
-x Display the map nickname translation table.
-Vn Version of ypbind, V3 is default.
