in the same was as the SunOS ypserv (same format, described in ypserv man
page). If the user wants tcpwrapper style access control, they can
recompile ypserv to use that instead. This way we get securenets without
having to ship libwrap.a and tcpd.h with core FreeBSD distribution.
If /var/yp/securenets doesn't exist, ypserv allows all connections.
equivalent to the old ypserv, except that it doesn't support the
-p [port] option to force the server to use a particular port.
The server stubs and yp.h header file are auto-generated from the yp.x
protocol definition file. The auto-generated XDR routines in libc/yp
are also used. The database access code has been broken out into a
seperate module so that other NIS utilities (ypxfr in particular)
can use it.
Note that the old mknetid script is being temporarily moved here; it
will be replaced by an mknetid program which will eventually have
a home under /usr/src/libexec. (The existing script is actually
somewhat broken -- it doesn't handle hosts -- but this isn't a big
deal at this point since the netid.byname map is really only useful
fopr Secure RPC, which we don't have yet.)
